PER CURIAM. Joseph Smith appeals his convictions for first-degree murder, kidnapping, and capital sexual battery and his sentence of death. We have jurisdiction. See art. V, § 3(b)(1), Fla. Const. For the reasons that follow, we affirm the convictions and the sentences imposed by the trial court. I. FACTS AND PROCEDURAL HISTORY On February 20, 2004, Joseph Peter Smith was charged with one count of sexual battery by a person over eighteen years of age upon a child less than twelve years of age and one count of kidnapping for the alleged abduction of and sexual battery upon Carlie Jane Brucia, an eleven-year-old female. That same day, Smith was also indicted on one count of first-degree murder for the killing of Ms. Brucia. The trial court record reflects that on February 1, 2004, Carlie Brucia left the Sarasota home of a friend between 6:10 and 6:15 p.m. to walk home. The mother of the friend called Carlie’s mother to verify that permission had been given for the young girl to walk home alone. The mother advised that she had not given permission and immediately sent Carlie’s stepfather to transport Carlie. When the stepfather arrived at the house of the friend, Carlie had already left. At approximately 7:30 p.m., after attempts to locate Carlie failed, a 911 call was made to report her missing. Law enforcement officers canvassed the area where Carlie would have walked from her friend’s house to her home until 3 a.m. and continued the search throughout the morning of February 2, 2004. At approximately 12 p.m., a bloodhound tracked the scent of Carlie to the area behind a car wash located on Bee Ridge Road, where the dog suddenly lost her scent. The proprietor of the car wash was advised that police officers and dogs were outside the business, and that the police were securing the area. The proprietor spoke with law enforcement and learned that a young girl was missing. He informed law enforcement that he had motion-sensitive cameras installed around the car wash and offered to review them to see if anything of use had been captured. A recording from one of the cameras, which was located at the rear of the car wash, revealed that at approximately 6:21 p.m. a girl (subsequently identified as Carlie) was led away from the car wash by a man dressed in what appeared to be a mechanic’s uniform. On the evening of February 2, 2004, a video of the apparent abduction was released to the media and an Amber Alert was issued for Carlie. On the morning of February 3, 2004, the wife of a former business associate of Smith saw the video on television, recognized the man in the video as Smith, and asked her husband to also view the video. The husband watched the video a number of times and recognized the man in the video as Smith: I worked with him at the shop, so I knew what he looked like. The sneakers, the back of his — the way his hair was cut, the way that he walked, his gait was just like Joe walking through the shop. I mean, he’s got a different type of walk to him. And then when I watched him ... reach for the girl ... the way he reached for it was — I’ve seen him pick up tools like that, you know.... I knew it was him. The husband called the police, spoke with Detective Vincent Riva, and provided Riva with Smith’s current address. Riva and his partner proceeded to the address in an unmarked vehicle and were met there by two other officers. After a neighbor advised that someone was in the residence, the detectives approached the front door and knocked, but when no one responded, a detective called his supervisor and was advised that Smith was on probation. He then called Smith’s probation officer and asked her to respond to the address. After the officers had been at the residence for approximately forty-five minutes, Smith’s sister arrived at the scene and advised that she would retrieve her brother. When Smith exited the house, a detective interrogated Smith with regard to his activities on the day of the abduction without specifically asking whether he had been at the car wash. Smith provided a timeline of his actions on February 1, which did not place him at or near the car wash that day. When a detective requested permission to examine Smith’s tattoos, Smith inquired as to the purpose of the visit by law enforcement. A detective advised that they were investigating an abduction, to which Smith replied that he had no knowledge of an abduction. When Smith was confronted with a still photo from the car wash video, Smith responded: “That looks like me, but it’s not me.” A detective requested permission from Smith to search both the room in the house that Smith rented and his car, which was parked at that location. Smith consented and signed a written consent form. The search of Smith’s room did not reveal anything of evidentiary value (although the detective did see a number of mechanic’s uniforms in the closet). However, when Smith’s vehicle was searched, a spoon was discovered under the front seat which appeared to have been used to melt or burn narcotics. A search of the trunk of the car revealed a cardboard box, which contained another spoon similar to the first and a syringe. When the probation officers arrived, the officers advised them of the items found in the car, and Smith was arrested for violation of probation and possession of drag paraphernalia. As the vehicle search was being conducted, an owner of the house where Smith was living arrived in a yellow station wagon. When asked about Smith’s whereabouts on February 1, she recalled that at around 6:30 p.m., Smith had engaged in a telephone call with his estranged wife from that residence. The detective explained that based on this information, the homeowner had basically established an alibi for Smith, he was “temporarily cleared” in the investigation, and the detectives left the residence to pursue other leads in the abduction case. However, later that day at approximately 6:30 p.m. (Tuesday, February 3), the husband of the woman with whom the detectives had interacted at the residence earlier that day appeared at the police station and informed the detective that his wife’s recollection of the events from the evening of February 1 was inaccurate. The husband explained that Smith had borrowed his yellow station wagon at approximately 3 p.m. on February 1 and did not return it until approximately 7 a.m. on February 2. The husband also identified Smith as the individual on the car wash video and relinquished the station wagon to the Sarasota County Sheriffs Office (SCSO). After receiving Miranda warnings from the detective assigned to the abduction case, Smith invoked his right to counsel. During the evening of February 4, 2004, John Smith, the brother of the defendant, arrived at the SCSO and was interviewed by FBI agents. John informed them that although he was not on good terms with his brother, he had received a phone call from Smith at approximately 8 p.m. on Sunday, February 1, the night of the abduction. John refused to speak with his brother at that time. On Monday night, John and his girlfriend saw the abduction video on television. John recognized his brother in the video based upon the abductor’s face and hair, and the fact that the abductor was wearing a mechanic’s uniform. The girlfriend believed that the abductor was Smith because Smith had a distinctive walk due to prior back surgery. That same night, Smith appeared at John’s house at approximately 11 p.m. Smith was apparently under the influence of drugs, and John sent his brother away. When asked if he could identify that the abductor captured on video was his brother, John replied: I don’t have any concrete evidence[,] it’s just, it looks like him, it walks like him, the more I look at that video, the more I look at him, the more I look at the video[,] it just well, total resemblance, if it’s not him. During the interview, the FBI agent asked, “Have you ever thought about going to see him and asking if he did this?” John replied that if Smith had abducted the child, he would not confess; instead, “he will die with that secret. If it’s him. You won’t get it out of him.” John then suggested that the only way to obtain any information from Smith would be to engage in trickery. John advised that if someone informed Smith that he or she had engaged in improper conduct similar to that for which Smith was being investigated, Smith would most likely open up and provide details about his own actions. Later that evening, after the interview concluded, John informed the FBI agent that he wanted to see his brother. SCSO personnel advised the FBI agent that Smith had retained counsel, and any meeting would need to go through Smith’s attorney. The next morning, Thursday, February 5, 2004, the public defender arranged a meeting between Smith, John, and their mother. The mother exited the interview room after approximately forty-five minutes, and John remained with Smith for an additional thirty minutes. When he exited the interview room, John commented that Smith “came close, but he didn’t say anything.” After exiting the room, neither John nor his mother was debriefed by law enforcement, and no surveillance was placed upon them when they left the building. On the evening of February 5, 2004, John called the FBI agent from his cell phone and stated: “I guess you heard, what do you want to do?” Although John’s cellular phone had never been tapped by law enforcement, John apparently believed that it had, and the FBI agent then realized that Smith must have provided John with information about Car-lie. Two FBI agents along with one local officer travelled to John’s residence, and John then directed the law enforcement officials to a local church. When they arrived at the church, John provided the investigators with an area in the field behind the church where they should look for a body. While at the church, John received a call from Smith. John eventually confirmed that Carlie’s body was located approximately fifty yards from a group of concrete blocks out in the field. After other officers arrived at the church and based upon the directions provided by John, Carlie’s body was found in a wooded area of the field. She was lying on her back, naked below the waist except for a sock on her right foot, with her right leg stretched out and her left leg bent back and curled under her left buttock. A deep ligature mark was visible on her neck. The FBI agents returned to the SCSO with John to obtain a second statement. John confessed to the agents that he lied to them during the morning meeting when he stated that Smith had not made any statements about Carlie. John now related that Smith had initially said, “I’m sorry I did this to you.” After Smith’s mother left the room, Smith informed John that on the night in question he ingested what he believed was cocaine and that everything that occurred afterwards was a blur. According to John, “It felt like he was afraid to say ‘you know she’s dead’ so I just said, ‘okay, Joe she’s dead, fine, where is she? Where is she? We gotta find her. Where is she?’ ” Smith then revealed that Carlie was in a field near a church on Proctor Road. John advised the agents that he had not provided them with this information after the earlier meeting because he did not believe his brother and because Smith never stated that he had murdered Carlie. John explained that after he left the jail with his mother, they proceeded to the church on Proctor Road, and John looked for the body without success. That night, John spoke with Smith by telephone and advised him that he had been to the church but could not find the body. Smith then informed John that he had engaged in a sexual act with the girl in the car, and “it got carried away.” When John asked if Smith had sexual intercourse with her, Smith responded in the affirmative. When John inquired if Carlie was dead, Smith responded, “I don’t know, she could be.” John decided to call the FBI agents after Smith admitted the sexual conduct and because, when John asked for specific details with regard to Carlie’s location, Smith requested his attorney. John also revealed that during the phone call at the church, Smith admitted that he had “rough sex” with Carlie before he strangled her. Subsequent to his arrest, Smith was transferred from the Sarasota County Jail to the Manatee County Jail. Before Smith’s capital trial, discussions between Smith and family members were recorded at the jail and were later played in the presence of the jury during the trial: February 9, 2004— MOTHER: Oh, Joe, the best thing that ... you can do is try to explain it was an accident. SMITH: But it was an accident, Mom. MOTHER: I know that Joe. SMITH: You don’t think I would do that on purpose, Mom. MOTHER: No. No, I don’t. I don’t think so at all Joe. Not at all. I know you better than that. But everyone ... is up in arms, the community, the press, the ... governor, the mayor. You just don’t know, Joe. SMITH: Yeah, Mom. You know what my charges are, right? MOTHER: Yeah, I do. Yeah, I do. You want me to tell [your estranged wife] anything? SMITH: Yeah, Mom. Teh her that— does she know what happened, the drugs and everything? MOTHER: Yeah, she knows. SMITH: That I didn’t mean to do it. She knows I’m not an animal, right? February 10, 2004,— JOHN: You had to have met the girl before, the young girl. SMITH: No. JOHN: Because she knew you. SMITH: No, John. JOHN: Not to mention the fact that she don’t look nowhere [sic] 11 years old. I was thinking 16 or 17. SMITH: That’s what I thought, too. February 19, 2004■ — ■ JOHN: How much time did you spend with her? SMITH: It was — I was so far out there. You know, I ... JOHN: [D]id it happen right there and then you drove there? SMITH: It wasn’t very long. JOHN: An hour? Two hours? Did you go back afterwards to look again? What made you pick that place? SMITH: Quiet. JOHN: She started something in the car? SMITH: Yeah. JOHN: Where did you finish? There? And what made you finish it? SMITH: [Inaudible] scared. JOHN: Scared? SMITH: I’m telling you. The adrenaline. I don’t know. I just, I don’t know. JOHN: Oh, what’s some more things that I — like you were just driving around and you copped, right? SMITH: John, I was doing in the car and everything and— JOHN: And then what? You saw her walking? SMITH: Yeah. Actually running. JOHN: And then you parked somewhere. SMITH: Uh-huh. Yeah.... SMITH: I do love [my daughter]. I didn’t do any of this to hurt anybody. JOHN: What I originally ... wanted to do way back in the beginning, I never got to do it because I couldn’t find it, remember I wanted to open (inaudible) shop? SMITH: Yeah. JOHN: Didn’t happen. I couldn’t find the material. SMITH: That was bad. That was a bad idea anyway. JOHN: You’re probably right, but he [sic] could have sold it for big, big bucks. Your kids could have went to college. SMITH: No. John, it was a bad, bad idea. Not only because of what it would have done to you, to be there and see that, but they would have followed you and they would have implicated you. SMITH: Tell mom this, okay? Because [the priest] came, I talked to him for quite a while about, you know, how I was brought up.... And then I did an Act of Contrition, which means he wipes all my sins away. You know, we did confession. I confessed to everything. Murder, all types of stuff. You know what I mean? Anything that could be— you know, I just confessed to everything. In addition to these conversations, on April 9, 2005, a letter from Smith to John, written in code, was intercepted by jail personnel. During trial, a cryptanalyst testified that the code had been broken and the message contained in the letter was the following: I WLSH L HAD SOMETHLN JULCY TO SAY OH OK THE BACKPACK[] AND CLOTHES WENT IN FOUR DIFFERENT DUMPSTERS.... I LEFT IT OUT IN THE OPEN I DRAGED THE BODY TO WHERE ST WAS FOUND DESTROY THIS AFTER DECIFERING IT AND SHUT UP. Sarasota County medical examiner Dr. Vincent Vega concluded that Carlie died as a result of strangulation because there was a ligature mark around her neck, and there were no other evident injuries to her head or torso. Dr. Vega testified that a shoelace was consistent with the type of ligature that would make the indentations on her neck. The marks on the neck were deeper in the front than in the back and appeared to criss-cross in the back. These findings led Dr. Vega to conclude that during the strangulation, the ligature was not tied, but was held in the perpetrator’s hands while he was standing behind the victim. Dr. Vega explained that if sufficient pressure is continuously applied to cut off the blood supply to the brain, unconsciousness will ensue in approximately eight to ten seconds; however, application of this pressure must continue for two to four minutes for death to result. Although Dr. Vega did not locate any defensive injuries on the body, he noted that ligature marks were found on the victim’s wrists, indicating that she had been bound. There were also bruises on the inside of her right thigh and in the shin area of her right leg indicative of blunt-force trauma. Dr. Vega testified that these bruises could have been caused by a struggle with the perpetrator. Dr. Vega also testified that abrasions on the side of the body indicated that the victim had been dragged. Oral, anal, and vaginal swabs obtained from the body tested negative for semen. However, Dr. Vega testified that the presence of insect larvae and decomposition of the body impeded his ability to obtain optimal results from such testing. Dr. Vega further testified that he observed damage to the hymen membrane of the child. According to Dr. Vega, this injury was consistent with a pre-mortem loss of tissue due to penetration (i.e., sexual activity). However, Dr. Vega also noted that the larvae present on the victim could have caused the hymenal defect, and it merely appeared that the victim had suffered a premortem injury. Dr. Vega expressed the opinion that, based upon all of the available evidence, the victim had been sexually battered. In support of this conclusion, Dr. Vega explained that case reports and studies have demonstrated that ligature strangulations are most common in female victims and are highly associated with sexual batteries. Dr. Vega also reached his conclusion based upon the state of the victim’s clothing when she was found; i.e., she was naked from the waist down. Lastly, Dr. Vega reached his conclusion based upon Smith’s statements and DNA testing results which revealed the presence of semen on the back of Carlie’s shirt. An FBI team supervisor testified that the semen sample found on Carlie’s shirt matched Smith’s DNA profile at all thirteen relevant locations on the DNA strand. The supervisor testified that the likelihood of randomly selecting a DNA profile of a Caucasian male that matched the DNA sample found on the shirt was 1 in 32 quintillion. An FBI hair-and-fiber analyst testified that two head hairs recovered from the yellow station wagon that had been relinquished to the SCSO were consistent with the hair of the victim. Further, seven fibers that were removed from the station wagon were consistent with the fibers contained in the red shirt that Carlie was wearing on the day of her abduction and murder. Smith chose not to testify on his own behalf and waived his guilt-phase closing statement. The jury convicted Smith of first-degree murder, sexual battery upon a child less than twelve years of age, and kidnapping. During the penalty phase, the State presented evidence that Smith was on drug offender probation during the time of these crimes. Dr. Vega testified that he believed Carlie was conscious when the ligature was applied to her throat because there was no evidence of an injury that would have produced unconsciousness. Moreover, the ligature marks on the wrists indicated that she was restrained. Finally, the State offered victim-impact statements written by Carlie’s father, mother, stepfather, and a teacher. Smith presented nineteen penalty-phase witnesses, who provided the following evidence: (1) Smith was extremely helpful to his friends, family, and neighbors; (2) Smith loved animals; (3) Smith’s father had a drinking problem; (4) Smith appeared to have a good relationship with his children and loved them; (5) Smith began taking drugs at an early age, and addiction and relapse pervaded his adult life; (6) Smith suffered from chronic back pain and became addicted to prescription drugs; (7) Smith had expressed the desire to cease his drug use; (8) Smith’s life began to unravel after he discovered the body of his best friend after a drug overdose; (9) Smith had been hospitalized or admitted to treatment programs for his drug addiction over a period of years and also for depression and suicidal thoughts; (10) Smith had no disciplinary problems and had not engaged in violent acts while he was in jail; (11) Smith sought spiritual counseling; and (12) if Smith received a life sentence, he would be housed at the highest level of security, and it was highly unlikely that his security status would ever change. Smith declined to testify during the penalty phase; however, he requested an opportu nity to make an allocution statement before the jury. The trial court declined to permit allocution before the jury unless Smith agreed to be subject to cross-examination by the State. Smith was allowed to provide such a statement during the later Spencer hearing. In rebuttal, the State presented a letter written by Smith to another inmate housed in the Manatee County Jail that had been intercepted. The letter expressed a desire for violence on his brother John and requested that a violent act be committed upon another inmate. On December 1, 2005, the jury recommended a death sentence by a vote of ten to two. During thé Spencer hearing, defense counsel explained that he would not call any experts to testify with regard to mental-health mitigation and would only introduce this mitigation through documentary evidence. The trial court inquired of both defense counsel and Smith with regard to this decision. Smith then offered the testimony of Dr. Vega, who testified that when he viewed the photos of Smith, he identified injection marks that were consistent with intravenous drug use. Smith offered an allocution statement to the court which provided, in part: After a little time went by, I had called my wife and I had asked to come home, but on February 1st, I found out that she didn’t want me.... I lost my business, my family, and my self-control was really coming apart fast. I just wanted to die on that day. So I went out, copped a bunch of heroin, cocaine, and began injecting it hoping I would overdose .... I was so high, I’ve never experienced a high like that. It was different than any other time. I think it was mixed with something else. ... I want you to know that I take Ml responsibility for the crimes. I don’t know how this all happened. I was very angry at myself and very high. I knew that getting high was wrong but I could not stop.... I’m not trying to make excuses for what happened, but I really don’t remember much about anything on that day after about 4:00 p.m. On March 15, 2006, the trial judge sentenced Smith to death for the murder. The trial court determined that the State had proven beyond a reasonable doubt the existence of six statutory aggravators: (1) Smith committed the felony while he was on probation, see § 921.141(5)(a), Fla. Stat. (2003) (moderate weight); (2) the murder was committed while Smith was engaged in the commission of a sexual battery or kidnapping, see § 921.141(5)(d), Fla. Stat. (2003) (significant weight); (3) the murder was committed for the purpose of avoiding lawful arrest, see § 921.141(5)(e), Fla. Stat. (2003) (great weight); (4) the murder was especially heinous, atrocious or cruel (HAC), see § 921.141(5)(h), Fla. Stat. (2003) (great weight); (5) the murder was cold, calculated, and premeditated (CCP), see § 921.141(5)(i), Fla. Stat. (2003) (great weight); and (6) the victim was under twelve years of age, see § 921.141(5)(Z), Fla. Stat. (2003) (great weight). The trial court concluded that Smith had failed to prove the existence of any statutory mitigating circumstances. The trial court found a total of thirteen non-statutory mitigating circumstances: (1) a long and well-documented history of mental illness (moderate weight); (2) a long and well-documented history of drug abuse (moderate weight); (3) longstanding severe pain from back injuries that contributed to his addiction (little weight); (4) Smith repeatedly sought help for his problems (little weight); (5) Smith was repeatedly denied treatment or received inadequate treatment (little weight); (6) positive qualities, including-(a) skills as a mechanic, plumber, and carpenter; (b) performance of kind deeds for others; (c) love and support with his family; (d) despite his incarceration, attempts to exert a positive influence on family members; (e) artistic skills; and (f) he cares about animals (moderate weight); (7) providing information that led to the resolution of this case (very little weight); (8) his family assisted law enforcement with Smith’s knowledge and cooperation (slight weight); (9) demonstration of spiritual growth (moderate weight); (10) maintenance of gainful employment (slight weight); (11) he is á loving father to his three daughters (moderate weight); (12) remorse (little weight); and (13) he is amenable to rehabilitation and a productive life in prison (little weight). In imposing a sentence of death, the trial court found that the aggravating circumstances in the case far outweighed the mitigating circumstances. The trial court also held that, with the exception of the probation aggravator, “[e]ach one of the aggravating factors in this case, standing alone, would be sufficient to outweigh the mitigation submitted in this case.” This direct appeal followed. The State has filed a cross-appeal, which presents a single claim. II. DIRECT APPEAL A. Confrontation — DNA testimony Smith first asserts that the State violated the Confrontation Clause of the Sixth Amendment to the United State Constitution when it failed to present the biologists who performed the DNA tests on the known sample taken from Smith and the unknown semen sample taken from the victim’s shirt. According to Smith, this highly significant forensic evidence required cross-examination of the person(s) who conducted the actual tests. During trial, the State instead presented the testimony of the FBI team supervisor, a forensic DNA examiner who interpreted the data, formulated the conclusions, and prepared the official report. In evaluating whether a Sixth Amendment violation occurred, it is essential to examine the role of the team supervisor in the evaluation of the semen sample found on the victim’s shirt. During a proffer, the supervisor explained her role as the manager of a DNA-analysis team as follows: I determine what items of [sic] exams will be conducted on which items. And I have the biologists who actually do[ ] the bench work for me. I then draw the conclusions, interpret their results and write the report and then testify, if needed. When further asked to explain her duties as a team supervisor, she explained: I manage the case, the case comes in, it gets assigned to me to be the DNA or serology manager. By that it means that I am in charge of talking with the contributors, determining what items will be worked. Then from there determining what stains will be worked. If the biologists have a question, they, you know, they can always come and talk to me about what exams to do and if further testing needs to be done. When asked if she interprets the results of the tests conducted by the biologists on her team, the supervisor responded, “Yes, I do. I draw all the interpretations and all the conclusions based on their work— an example would be if they test for blood, they will write the results of the test, but then it is my interpretation that says blood is there on that item of evidence.” (Emphasis supplied.) She also testified that this protocol is standard for the FBI serology/DNA lab. The supervisor also explained that the biologists on her team make notes and keep records of every test that they complete on a sample, that the notes become part of the file in the ease, and that she uses the notes to reach her conclusions and prepare the final report. The supervisor testified that she was the individual who compared the DNA sample taken from the victim’s shirt to that of Smith and determined that these specimens matched at all thirteen relevant locations on the DNA strand. She was also the individual who calculated the probability of selecting an unrelated individual at random from the pertinent sample group who would have the same DNA profile as that found on the shirt. In Crawford v. Washington, 541 U.S. 36, 124 S.Ct. 1354, 158 L.Ed.2d 177 (2004), the United States Supreme Court held that testimonial out-of-court statements that are introduced against a defendant violate the Confrontation Clause unless the de-clarant is unavailable and the defendant had a prior meaningful opportunity to cross-examine that witness. See id. at 68-69, 124 S.Ct. 1354. Smith contends that this ease presents the same issue as that confronted in State v. Johnson, 982 So.2d 672 (Fla.), cert. dismissed, — U.S.-, 129 S.Ct. 28, 171 L.Ed.2d 930 (2008), and that Johnson should control the outcome here. In Johnson, this Court held that a report prepared by a Florida Department of Law Enforcement analyst, which established the illegal nature of the substances that Johnson possessed, was admitted in violation of Crawford where the analyst who prepared the report did not testify during trial — instead, the report was introduced through her supervisor. See 982 So.2d at 673-74. We concluded that the report was testimonial in nature because the report there was clearly prepared in anticipation of trial and designed to establish an element of the crime. See id. at 680. An accusatory document such as the report there should only be admissible where the preparer is unavailable and the defendant had a prior opportunity to conduct cross-examination of the person who prepared the report. See id. at 680-81. Similarly, in State v. Belvin, 986 So.2d 516, 518 (Fla.2008), we held that admission of a breath-test affidavit violated the Confrontation Clause where the technician who performed the test did not testily during trial. Thus, in each of these cases, the person who prepared the report of the relevant results did not testify. See also Johnson v. State, 929 So.2d 4, 6 (Fla. 2d DCA 2005) (noting that the supervisor “did not conduct this particular test, but he was able to testify about the general procedures used by FDLE in preparing such reports”). We have carefully considered both Florida and federal cases, and we conclude that the instant case is distinguishable from both Johnson and Belvin. Here, it was the supervisor in her capacity as the head of an FBI DNA-analysis team who evaluated the raw test results obtained by the biologists on her team and compared the DNA sample found on the victim’s shirt to the sample taken from Smith. She was the person who concluded that Smith’s DNA matched the DNA from the shirt and calculated the probability of a random individual from the pertinent sample group submitting a DNA sample that matched the sample obtained from the shirt. Thus, although the FBI team supervisor did not perform each actual test on the material found on the shirt and the buccal swab taken from Smith, she was the person who interpreted the data obtained from the testing and formulated the conclusions that incriminated Smith in the sexual battery. Thus, while the results that the supervisor obtained in this case were indubitably testimonial in nature, she was present at trial and subject to cross-examination with regard to those results. At least two federal courts have held that the Sixth Amendment Confrontation Clause does not require an expert to have performed the actual laboratory work to permissibly testify with regard to conclusions that he or she has drawn from those results. In United States v. Moon, 512 F.3d 359, 362 (7th. Cir.), cert. denied, U.S. -, 129 S.Ct. 39, 172 L.Ed.2d 19, and cert. denied, — U.S.-, 129 S.Ct. 40, 172 L.Ed.2d 19 (2008), the Seventh Circuit Court of Appeals concluded that “the Confrontation Clause does not forbid the use of raw data produced by scientific instruments, though the interpretation of those data may be testimonial.” (Emphasis supplied.) Similarly, the Fourth Circuit Court of Appeals held that a Confrontation Clause violation did not occur where the chief toxicologist of a lab reviewed the data from tests conducted by technicians at the lab and issued a report based upon that data where the toxicologist testified at trial with regard to his conclusions. See United States v. Washington, 498 F.3d 225, 228 (4th Cir.2007) (“While Dr. Levine did not see the blood sample and did not conduct any of the tests himself, three lab technicians operating under his protocols and supervision conducted the tests and then presented the raw data from the tests to him.”). We find the rationale followed by the federal courts in Moon and Washington to be persuasive with regard to the challenge raised by Smith. Accordingly, even though the FBI team supervisor did not actually perform the testing to extract DNA samples from the shirt and from Smith, her testimony did not implicate the Confrontation Clause because she, as supervisor, formulated her own conclusions from the raw data produced by the biologists under her supervision and control on her team, and she was subject to cross-examination with regard to those conclusions. Accordingly, relief on this claim is denied. B. Sexual Battery Opinion Testimony Smith next asserts that the trial court erred when it permitted Dr. Vega to present opinion testimony that the victim had been sexually assaulted. Smith asserts that to allow Vega to testify with regard to commonly understood facts invaded the province of the jury and created the possibility that the jury would forgo independent analysis of the evidence to determine whether a sexual battery occurred. We have explained that “[t]he determination of a witness’s qualifications to express an expert opinion is peculiarly within the discretion of the trial judge, whose decision will not be reversed absent a clear showing of error.” Ramirez v. State, 542 So.2d 352, 355 (Fla.1989). Section 90.702, Florida Statutes (2005), provides: If scientific, technical, or other specialized knowledge will assist the trier of fact in understanding the evidence or in determining a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify about it in the form of an opinion; however, the opinion is admissible only if it can be applied to evidence at trial. Section 90.704, Florida Statutes (2005), further provides guidelines for the data upon which an expert may rely to reach an opinion or conclusion: “If the facts or data are of a type reasonably relied upon by experts in the subject to support the opinion expressed, the facts or data need not be admissible in evidence.” This Court has previously allowed a qualified expert to testify that, based upon the circumstances surrounding the discovery of the victim’s body, a sexual battery likely occurred. Specifically, in Dailey v. State, 594 So.2d 254, 258 (Fla.1991), this Court addressed and rejected a challenge similar to that raised by Smith here: During the penalty phase, the judge qualified Detective Halliday as an expert in homicide and sexual battery and allowed him to testify that because the victim’s body was found nude and her clothing scattered, it was highly likely that a sexual battery or attempt had occurred. Dailey claims that this testimony was only common sense and it was error for the court to permit expert testimony on a matter that is within the common understanding of the jury. Halliday, however, had extensive training and experience in homicides and sexual batteries; his expert testimony was helpful in consolidating the various pieces of evidence found at the crime scene. This would not necessarily be within the common understanding of the jury. We find no error. We conclude that, with the exception of the testimony discussed below, the trial court did not abuse its discretion when it permitted Vega to present opinion testimony as to whether this victim had been sexually battered. During trial, Dr. Vega testified that various aspects of the crime scene were consistent with sexual battery: (1) the victim was discovered naked below the waist;' (2) there was evidence of tearing to the victim’s hymen, and one possible cause of that tearing could have been penetration during a sexual battery; (3) bruises on the body could have been caused by a struggle with her attacker; and (4) it is more likely that the victim’s jeans and underwear were removed before she was dragged to the location where her body was found, rather than pulled off while she was dragged, based upon the uniformity of the abrasions found. The fact that there were alternative explanations for the condition of the body does not render Dr. Vega’s testimony inadmissible. Rather, it was for the jury to decide what weight to accord Dr. Vega’s opinion based upon any alternative explanations. See Delap v. State, 440 So.2d 1242, 1253-54 (Fla.1983); see also Dailey, 594 So.2d at 258 (detective’s testimony that it was highly likely a sexual battery occurred was admissible because it “was helpful in consolidating the various pieces of evidence found at the crime scene”). The testimony of Dr. Vega assisted the jurors in deciding what happened, not who was responsible for the acts perpetrated against the victim. Cf. Martinez v. State, 761 So.2d 1074, 1079 (Fla.2000) (“[A] witness’s opinion as to the guilt or innocence of the accused is not admissible.”). Accordingly, we conclude that Dr. Vega’s opinion that the evidence pointed to a sexual battery here was properly admitted. We agree with Smith, however, that the trial court should have excluded one portion of Dr. Vega’s testimony — that ligature strangulation is “highly associated” with sexual battery. Dr. Vega failed to provide any basis whatsoever to support a purported connection or correlation between these two elements, no evidence of such a connection was found here, and Dr. Vega had no research, data, or other material from which he drew this conclusion. Since it is impossible to determine from Dr. Vega’s testimony whether the facts or data were of a type reasonably relied upon by experts to support the opinion expressed, it is impossible to evaluate whether Dr. Vega’s conclusion is scientifically supported or even valid. Absent adequate explanation of data, research, or other material from which this conclusion was drawn, we conclude that Dr. Vega should not have been allowed to express the opinion of a purported abstract connection between ligature strangulation and sexual battery. However, defense counsel did not object to this particular statement, nor did the defense ask Vega to provide more detail with regard to this statement during cross-examination. Accordingly, this challenge was unpreserved. We have held that “[t]he failure to contemporaneously object to a comment on the basis that it constitutes improper ... testimony renders the claim procedurally barred absent fundamental error.” Sexton v. State, 775 So.2d 923, 932 (Fla.2000) (emphasis supplied). To warrant reversal on the basis of fundamental error, “the error must reach down into the validity of the trial itself to the extent that a verdict of guilty could not have been obtained without the assistance of the alleged error.” Walls v. State, 926 So.2d 1156, 1176 (Fla.2006) (emphasis supplied) (quoting Brown v. State, 124 So.2d 481, 484 (Fla.1960)). We conclude that Dr. Vega’s testimony with regard to the ligature strangulation/sexual battery connection did not rise to the level of fundamental error. As previously discussed, there was a plethora of evidence, including semen that matched the DNA profile of Smith and Smith’s confession to his brother that he engaged in “rough sex” with the victim, to support a conviction on this charge. We have no doubt that even if Dr. Vega had not presented this testimony, the jury nonetheless would have convicted Smith of capital sexual battery. Accordingly, no harmful error occurred, and Smith is not entitled to relief on this basis. C. Statements by John Smith Smith next asserts that the trial court erred when it refused to suppress statements by his brother, John, which related to comments made by Smith with regard to the sexual battery and murder of the victim. According to Smith, John obtained these statements while he was acting as an agent of the FBI and the SCSO. We disagree. This Court has stated that “[a] trial court’s ruling on a motion to suppress comes to us clothed with a presumption of correctness and, as the reviewing court, we must interpret the evidence and reasonable inferences and deductions derived therefrom in a manner most favorable to sustaining the trial court’s ruling.” Connor v. State, 803 So.2d 598, 605 (Fla.2001) (quoting Murray v. State, 692 So.2d 157, 159 (Fla.1997)). Nevertheless, “mixed questions of law and fact that ultimately determine constitutional rights should be reviewed by appellate courts using a two-step approach, deferring to the trial court on questions of historical fact but conducting a de novo review of the constitutional issue.” Id. (citing United States v. Bajakajian, 524 U.S. 321, 336 n. 10, 118 S.Ct. 2028, 141 L.Ed.2d 314 (1998)). We have previously addressed the state-agent concept and the constitutional issues presented by the use of state agents: In Massiah [v. United States, 377 U.S. 201, 84 S.Ct. 1199, 12 L.Ed.2d 246 (1964) ], the United States Supreme Court announced for the first time that the Sixth Amendment prohibits law enforcement officers from interrogating a defendant after his or her indictment and in the absence of counsel. Consequently, statements “deliberately elicited” from a defendant after the right to counsel has attached and in the absence of a valid waiver are rendered inadmissible and cannot be used against the defendant at trial. 377 U.S. at 206[, 84 S.Ct. 1199], Nevertheless, incriminatory statements by a defendant will not be excluded merely because the statements are made after judicial proceedings have been initiated and in the absence of a valid waiver. Rather, law enforcement officials must do something that infringes upon the defendant’s Sixth Amendment right. While the “deliberately elicited” standard is clearly satisfied when the police directly interrogate or question a defendant in some fashion, it also may be satisfied by less direct types of questioning. See State v. Wooley, 482 So.2d 595, 596 (Fla. 4th DCA 1986). Usually, determining whether the “deliberately elicited” standard has been met becomes an issue in eases ... where incriminatory statements from a defendant were obtained through persons other than the police who allegedly acted as police informants or surrogates. Rolling v. State, 695 So.2d 278, 290 (Fla. 1997) (footnote omitted). We held in Rolling that “a violation of a defendant’s right to counsel turns on whether the confession was obtained through the active efforts of law enforcement or whether it came to them passively.” Id. at 291 (emphasis supplied). For example, in Malone v. State, 390 So.2d 338, 339 (Fla.1980), an inmate and a detective established a plan whereby the inmate would be transferred to another jail. The inmate would then visit the defendant in civilian clothes and tell the defendant that he had been released, and that the inmate would attempt to retain an attorney for the defendant. See id. We held that the trial court erred when it failed to suppress the defendant’s statements to the inmate indicating that the defendant had killed the victim and providing directions as to where the body was located. See id. In so holding, we concluded that the statements were “directly elicited by the State’s stratagem deliberately designed to elicit an inciiminating statement from [the defendant].” Id. (emphasis supplied); cf. Dufour v. State, 495 So.2d 154, 159 (Fla.1986) (inmate was not a state agent where the inmate approached the authorities on his own initiative and, after speaking with authorities, the inmate was “neither encouraged nor discouraged from obtaining further information”). We conclude that the record supports the determination by the trial court that John Smith was not acting as an agent of the State. First, both statements that John provided to FBI agents are transcribed in the record. Not once in either of these statements do the agents ask John to speak to his brother to determine whether Carlie was alive. While the agents on one occasion asked John, “Have you ever thought about going to see him and asking if he did this,” the agents did not further pursue this line of inquiry. It was John who volunteered that the only way to persuade Smith to talk would be to engage in trickery. However, in response to this statement by John, the agents did not request that he trick Smith in an effort to locate Carlie. The agents encouraged John to contact them further only if he had forgotten something. Further, after the morning meeting with Smith and his mother, when John informed the FBI agent that Smith “came close, but he didn’t say anything,” the agent did not question John further with regard to that statement. Second, there is no indication that law enforcement arranged the morning meeting between John, Smith, and their mother. During the hearing on the motion to suppress, an FBI agent testified that after John provided his first statement, he subsequently called and demanded to see his brother. The agent followed the chain of command and eventually informed John that it was not possible to arrange a meeting with Smith that night because Smith had requested an attorney. SCSO personnel confirmed that the FBI agent was informed that a visit was not possible that night and could only be arranged through the public defender. It was the public defender who eventually requested the visitation between John, his mother, and Smith. Thus, the record reflects that law enforcement did not affirmatively arrange the meeting between John and his brother. Instead, law enforcement initially blocked John from seeing Smith and required that he arrange a meeting through the public defender. Finally, John’s actions refute any contention that he was working as a State agent. John misled law enforcement with regard to the morning meeting with his mother and Smith. John then traveled with his mother to the church where Smith informed him that the victim’s body was located, and searched for the body. It appears that John may have been seeking some personal benefit for himself or his family, but not as a state agent. On February 19, 2004, when Smith advised John that it was a “bad idea” for John to search for the body, John replied, “You’re probably right, but he [sic] could have sold it for big, big bucks. Your kids could have went to college.” Finally, when Smith provided John with a note written in code that explained what happened to the victim’s belongings, John did not decipher the code for the State or relinquish the note voluntarily. The State was required to enlist the services of a cryptanalyst to decipher the message. Based on these record facts, and the absence of any facts to support the agency theory, we conclude that the trial court properly denied suppression of John’s statements. D. Juror Challenges Smith next challenges the trial court’s refusal to strike nine jurors for cause. According to Smith, each of the jurors he sought to strike for cause provided sufficiently equivocal responses to generate a reasonable doubt as to their fitness to serve as jurors in this case. We have described the duty of an appellate court to review denials of for-cause challenges as follows: The test for determining juror competency is whether the juror can lay aside any bias or prejudice and render a verdict solely on the evidence presented and the instructions on the law given by the court. See Lusk v. State, 446 So.2d 1038, 1041 (Fla.1984). “In evaluating a juror’s qualifications, the trial judge should evaluate all of the questions and answers posed to or received from the juror.” Parker v. State, 641 So.2d 369, 373 (Fla.1994). A juror must be excused for cause if any reasonable doubt exists as to whether the juror possesses an impartial state of mind. See Bryant v. State, 656 So.2d 426, 428 (Fla.1995). The trial court has broad discretion in determining whether to grant a challenge for cause, and the decision will not be overturned on appeal absent manifest error. Overton v. State, 801 So.2d 877, 890 (Fla.2001). Kopsho v. State, 959 So.2d 168, 170 (Fla. 2007). We have considered Smith’s challenges with regard to each of the nine jurors and agree with Smith that the trial court erroneously denied two for-cause challenges. The first juror whom the trial court should have stricken was juror number 29. Juror 29 indicated that he possessed knowledge about the case because one of his employment duties was to update the internal computer-information network for the business, and he “broke” news to his staff as this case unfolded. When the trial court asked juror 29 whether he had formed impressions about the case, he replied, “yeah,” after which the following dialogue occurred: COURT: Okay. Can you tell me what those are? JUROR: I have a daughter who is the same age that Carlie was and, you know, up until that time, we had allowed her to ride her bike in our neighborhood. Now, with things being what they are, we decided that all of that is now supervised even though she’s now 13. My impression being that, you know, having seen the videotape and everything that came out and that he made the confession, my thought is, okay, well, he’s accused, he probably did it. Those are the thoughts that are in my mind. COURT: Do you feel that that impression or opinion that you have ... is so strong that it would always color your decision, would affect your decision in this case? Or do you feel that you can completely set that aside and any decision that you would make in this case as to the guilt or innocence of Mr. Smith as it relates to these charges would be based solely on the evidence that you received here in this courtroom and my instructions to you on the law? Or do you feel that those impressions that you have are going to bleed over and might fill the gaps for you here at the trial? JUROR: Well, having a great respect for the judicial system, I think I would do my very best to be impartial and understanding that it would have to be based on the evidence. I would have to look at it in a very black and white manner, which is what I would like to consider myself being, a person of integrity who would be able to say that, you know, if this is what the law says, then we have to go by what the law says. So, for me, it would be a matter of integrity. (Emphasis supplied.) Although juror 29 eventually stated that he would follow the law as a “matter of integrity,” we conclude that this statement was totally insufficient to overcome (1) his expressed opinion that Smith “probably did it,” (2) his employment duty to follow the Brucia case and provide updates to his coworkers, and (3) the fact that he changed his behavior towards his daughter based upon the events of the instant case. We also conclude that the trial court erred when it refused to strike juror 89 for cause. Juror 89 painfully explained that he had been a witness in a capital case where his daughter was murdered and that the experience was “[v]ery, very painful.” When questioned further by the State, the prospective juror professed that “time is a great healer,” and stated that that he could follow the instructions given by the trial court as well as be fair during the trial. It is apparent from voir dire that this juror sincerely felt that he could be fair and impartial if he were selected to serve on this case. Although we do not question this sincerity, we nonetheless conclude that the trial court should have stricken juror 89 for cause. Despite the earnest expression of beliefs and the good intentions of juror 89, we cannot accept that a parent who testified as a witness during his own daughter’s murder trial could not be influenced, albeit unintentionally, by such a painful and tragic experience. Although these two jurors should have been stricken for cause, Smith is not entitled to relief because the failures here constituted harmless error. We have explained that “where a trial court has awarded additional peremptory challenges to a defendant, each such additional challenge is treated as having replaced one that was expended on a juror who should have been but was not struck for cause.” Conde v. State, 860 So.2d 930, 942 (Fla. 2003). Accordingly, “[a] defendant cannot demonstrate prejudice if the trial court grants the same number of additional per-emptories as cause challenges that were erroneously denied.” Busby v. State, 894 So.2d 88, 97 (Fla.2004). The trial court here granted Smith three peremptory challenges in addition to the original ten challenges that he received. Thus, because the failure to strike jurors 29 and 89 constitutes harmless error, Smith is not entitled to relief. E. Admission of Photographs In his next challenge, Smith contends that the trial court erroneously admitted photos of the victim’s body. The standard of review for the admission of photographs is abuse of discretion. See Davis v. State, 859 So.2d 465, 477 (Fla. 2003). This Court has explained: “The test for admissibility of photographic evidence is relevancy rather than necessity.” Crime scene photographs are considered relevant when they establish the manner in which the murder was committed, show the position and location of the victim when he or she is found by police, or assist crime scene technicians in explaining the condition of the crime scene when police arrived. This Court has upheld the admission of autopsy photographs when they are necessary to explain a medical examiner’s testimony, the manner of death, or the location of the wounds. However, even where photographs are relevant, the trial court must still determine whether the “gruesomeness of the portrayal is so inflammatory as to create an undue prejudice in the minds of the jur[ors] and [distract] them from a fair and unimpassioned consideration of the evidence.” In making this determination, the trial court should “scrutinize such evidence carefully for prejudicial effect, particularly when less graphic photos are available to illustrate the same point.” Douglas v. State, 878 So.2d 1246, 1255 (Fla.2004) (alterations in original) (citations omitted) (quoting Pope v. State, 679 So.2d 710, 713 (Fla.1996); Czubak v. State, 570 So.2d 925, 928 (Fla.1990); Marshall v. State, 604 So.2d 799, 804 (Fla.1992)). The admission of photographs will also be upheld if they are “corroborative of other evidence.” Czubak v. State, 570 So.2d 925, 928 (Fla.1990). At the same time, the admission of the photographs of a deceased victim also “must be probative of an issue that is in dispute.” Almeida v. State, 748 So.2d 922, 929 (Fla.1999). Nonetheless, we have also explained that “[t]hose whose work products are murdered human beings should expect to be confronted by photographs of their accomplishments.” Chavez v. State, 832 So.2d 730, 763 (Fla.2002) (quoting Henderson v. State, 463 So.2d 196, 200 (Fla.1985)). Finally, with regard to the impact of gruesome photos upon the jury, this Court has noted: It is not to be presumed that gruesome photographs will so inflame the jury that they will find the accused guilty in the absence of evidence of guilt. Rather, we presume that jurors are guided by logic and thus are aware that pictures of the murdered victims do not alone prove the guilt of the accused. Henderson, 463 So.2d at 200. The record reflects that the trial court carefully considered each of the photographic exhibits and even requested that the State speak to Dr. Vega with regard to the photos that he thought would best illustrate his testimony. See generally Philmore v. State, 820 So.2d 919, 932 (Fla. 2002) (trial court’s preliminary screening weighed in favor of admissibility). The trial court also excluded some photos that were proffered by the State. For example, the trial court admitted photo 53 to illustrate the testimony that the victim’s wrists were bound, but excluded photos 54 and 55. We consider the challenged photos based upon the purpose for their admission. Exhibits Sk and 35A — These photos depict the body of the victim as she was discovered in the field behind the church. Exhibit 34 is a side view of the lower half of her body. Exhibit 35A, which is clearly the more graphic of the two, is a photo taken from the foot of the body and depicts the victim’s spread legs and exposed genitalia. The image reflects decomposition of, and insect larvae on, the body. One of the disputed issues during trial was whether the victim was sexually battered. Dr. Vega testified that vaginal and anal swabs taken from the body tested negative for sperm. However, Dr. Vega explained that optimal testing was compromised by the presence of larvae and decomposition. These two exhibits were relevant to Dr. Vega’s testimony that the genitalia of Carlie had been affected by outside forces, which may have played a role with regard to the lack of evidence of a sexual battery. Therefore, we conclude that the trial court did not abuse its discretion when it admitted these photographs. Exhibit J$ — This exhibit depicts the right calf of the victim, which exhibits prominent abrasions. Although animal predation on her ankle is visible, around this injury is larval activity. Dr. Vega utilized this exhibit to support his conclusion that the body had been dragged across a concrete-like surface before it was deposited in the field behind the church. On cross-examination, Dr. Vega agreed that the positioning of the victim’s shirt (i.e., pushed up on the right side of her body with her right shirt sleeve pulled down off of her right shoulder) could have been caused by the dragging of the body, but that most likely her jeans and undergarments had been removed before she was dragged based on the uniformity of the abrasions on her legs. The uniformity and smoothness of these abrasions also led Vega to conclude that the dragging occurred while the victim was either unconscious or dead. Accordingly, exhibit 42 was admissible and relevant to illustrate Dr. Vega’s testimony with regard to the nature and extent of the injuries, and also to establish the manner of, and circumstances surrounding, the victim’s death. See Philmore, 820 So.2d at 931 (citing Jackson v. State, 545 So.2d 260, 265 (Fla. 1989); Wilson v. State, 436 So.2d 908, 910 (Fla.1983)); see also Engle v. State, 438 So.2d 803, 809 (Fla.1983) (noting that admitted color photos were “especially useful in showing the drag marks on the victim’s body”). Exhibit 4.8 — This last contested exhibit depicts the inner thigh of the victim with two surgical incisions. Dr. Vega explained that when he first examined the body, he found what appeared to be a bruise on the inside of her thigh. He incised the skin in two places, and pooling of blood under the skin confirmed that at or around the time of death, she suffered a bruise to her inner thigh. Dr. Vega testified that such a bruise could have been caused by a struggle between the
