PER CURIAM. Eric Lee Simmons appeals an order of the circuit court denying his initial post-conviction motion filed under Florida Rule of Criminal Procedure 3.851 to vacate his conviction of first-degree murder and sentence of death. He also petitions this Court for a writ of habeas corpus. We have jurisdiction. See art. V, § 3(b)(1), (9), Fla. Const. As explained below, we affirm the postconviction court’s denial of relief as to Simmons’ guilt phase claims. We reverse the denial of relief as to the penalty phase and remand for a new penalty phase proceeding because counsel failed to fully investigate and present mitigating evidence regarding Simmons’ childhood and mental health. We deny Simmons’ petition for writ of habeas corpus. STATEMENT OF FACTS AND PROCEDURAL HISTORY Eric Simmons was convicted of the stabbing and beating death of Deborah Tres-sler, who was found dead in a wooded area in Sorrento, Florida. He was also convicted of kidnapping and sexual battery. The jury unanimously recommended a sentence of death and the trial court sentenced Simmons to death for the murder and to life in prison for each of the other charges. The facts of this case as set forth in pertinent part in the direct appeal opinion are as follows: The evidence presented at trial indicated that on December 3, 2001, at approximately 11:30 a.m., John Conley, a Lake County Sheriffs Office (LCSO) deputy, discovered the body of Tressler in a large wooded area commonly used for illegal dumping. The body was located some 270 feet from the main road. Crime scene technician Theodore Cush-ing took pictures of the body, performed a sketch of the area, and found five tire tracks near the body. The crime scene technicians took plaster cast impressions of the three tracks with the most detail for comparison purposes. Mr. Cushing noticed that the tire tracks indicated that a car made a three-point turn close to the body. All-terrain vehicle tracks were present closer to the body, but they appeared older and deteriorated. The medical examiner, Dr. Sam Guli-no, observed the victim and the surroundings at the scene on December 3, 2001, with the victim lying on her left side with her right arm over her face. Dr. Gulino estimated the time of death was twenty-four to forty-eight hours before the body was discovered. Dr. Gulino performed an autopsy, which revealed numerous injuries. Tressler suffered some ten lacerations on her head, as well as numerous other lacerations and scrapes on her scalp and face. There was a very large fracture on the right side of her head, and her skull was broken into multiple small pieces that fell apart when the scalp was opened. Dr. Gulino opined that this injury and the injuries to her brain resulted in shock and ultimately Tressler’s death. There was another fracture that extended along the base of the skull, resulting from a high-energy impact; bleeding around the brain; and bruises in the brain tissue where the fractured pieces of skull had cut the brain. There were numerous stab wounds on the neck, a long cut across the front and right portions of the neck, and other bruises and cuts. There was little bleeding from these injuries, indicating that the victim was already dead or in shock at the time of the injuries. The victim also suffered a stab wound in the right lower part of her abdomen that extended into her abdominal cavity and probably occurred after she received the head injury. There were also injuries to her anus with bruising on the right buttock extending into the anus, and the wall of the rectum was lacerated. These injuries were inflicted before death. Dr. Gulino opined that these injuries would be painful and not the result of consensual anal intercourse. The victim suffered numerous defensive wounds on her forearms and hands. There was also a t-shaped laceration on the scalp and an injury at the base of her right index finger that was patterned, as if a specific type of object, like threads on a pipe, had caused it. Dr. Gulino opined that the attack did not occur at the exact spot where Tressler was found because of the lack of blood and disruption to the area, but stated that the position of Tressler’s body was consistent with an attack occurring in that area. On December 4, 2001, Robert Bed-good, a crime scene technician, collected evidence from Tressler’s body during the autopsy. Dr. Jerry Hogsette testified that, based on the temperature in the area of Tressler’s body and the development of the insect larvae taken from Tressler’s body, Tressler had been killed between midnight on December 1, 2001, and early Sunday morning, December 2, 2001. Simmons v. State, 934 So.2d 1100, 1105-06 (Fla.2006) (footnotes omitted). Witness Andrew Montz also testified at trial. Montz was at the Circle K store near the intersection of State Road 44 and County Road 437 in Lake County late on the night of December 1, 2001, when he saw a white four-door car stopped at the traffic light. A woman opened the passenger side door and screamed for help but the driver pulled her back into the car and drove off. Id. at 1106. Montz testified that the car had a flag hanging from a window. Sherri Renfro testified she was at the same Circle K between 11:30 and 11:40 p.m. and saw a white car approach the intersection. She also saw the passenger door open and a woman screaming for help. Renfro yelled at the driver to stop but he did not, and Renfro got in her van and followed the white car but could not keep up. Renfro also noted the flag hanging from the window. Id. Montz and Renfro identified Simmons’ white car with a flag hanging from the window as the one each had seen at the intersection, and Renfro identified a photograph of Tressler as the woman she had seen screaming for help. Witness Jose Rodriguez knew Tressler from the laundromat where she worked, and testified that he often saw Simmons with Tressler, including on the night of December 1, 2001. Prior to Simmons’ arrest, Rodriguez was shown a photographic lineup and picked out a photograph that resembled Simmons. After officers learned Simmons drove a white car matching the car seen at the Circle K, sheriffs detectives Stewart Perdue and Kenneth Adams, along with fifteen other officers and a helicopter circling overhead, found Simmons at his parents’ home. The detectives spoke briefly to him and then asked him to accompany them to the sheriffs office to talk. Simmons consented and was handcuffed for the trip to the sheriffs office, but the handcuffs were removed when he arrived. Once at the sheriffs office, Simmons was advised of his Miranda rights, which he waived, and the detectives questioned him for approximately four hours, two of which were recorded on videotape. Simmons maintained throughout the interrogation that he did not murder Tressler. He told the detectives that he was with Tressler that day and, after trying to watch the Florida-Tennessee football game at his apartment in Mount Dora, she asked to be taken to the laundromat or her trailer because Simmons’ television reception was so poor. Simmons told detectives that he dropped Tressler off at the laundromat and then returned to his apartment. Although Simmons told officers he had sexual relations with Tressler two weeks before her death, his semen was later reported to have been found in her vagina. During Simmons’ interrogation by detectives Perdue and Adams, the detectives learned that blood had been found in Simmons’ car. At that point, which occurred when the interrogation was not videotaped, the detectives informed Simmons that blood was found in his car and he responded, “Well, I guess if you found blood in my car, I must have did it.” Blood found in his car was later determined to belong to Tressler after DNA testing was performed. Casts made from tire tracks found near Tressler’s body were found to match two of the tires on Simmons’ car. The rear tires of his car were different brands and were consistent with two of the three tire casts taken at the scene. The jury convicted Simmons of first-degree murder, kidnapping, and sexual battery using force likely to cause serious injury. The case proceeded directly to the penalty phase, at which the defense presented two mitigation witnesses — jail officer Sergeant Craig Leslie and Simmons’ sister, Ashley Simmons. By special interrogatory verdict, the jury unanimously found three aggravating factors had been proven and recommended a sentence of death. Subsequent to the penalty phase jury proceeding, the trial court held a Spencer hearing at which the defense presented Dr. Elizabeth McMahon, who testified that Simmons had a moderate to severe learning disability and no significant history of violence. The trial court entered an order imposing the death sentence based on finding and weighing three aggravators against eight nonstatutory mitigators. On direct appeal, we affirmed. Although we concluded that methods used by law enforcement in obtaining the eyewitness identification made by Montz and Renfro of the vehicle and Tressler were highly suggestive, we concluded the testimony was admissible because, based on the totality of the circumstances, the identification procedure did not give rise to a substantial likelihood of irreparable mis-identification by Montz and Renfro. See Simmons, 934 So.2d at 1118-19. We also found no merit in Simmons’ other claims, including his claim that the trial court erred in denying his motion to suppress his statements made to the detectives. Simmons’ motion contended that the statement was the product of an arrest made without probable cause. See id. at 1113— 14. Motion for Postconviction Relief Simmons filed his initial motion for post-conviction relief under Florida Rule of Criminal Procedure 3.851 in 2008, raising six claims, some with multiple subissues. An evidentiary hearing was held in December 2009 and January 2010 on all his post-conviction claims except his claim challenging the constitutionality of lethal injection. Forty-three witnesses testified and numerous exhibits were introduced into evidence, although Simmons did not testify at the evidentiary hearing. On August 23, 2010, the circuit court entered its eighty-seven-page order denying postconviction relief. The details of the postconviction court’s ruling that are pertinent to the issues raised in this appeal will be discussed when we discuss each issue below. In this appeal, Simmons raises five claims, some with multiple subissues. He has also filed a petition for writ of habeas corpus in this Court, raising two claims. We will discuss each issue in turn. ANALYSIS I. Guilt Phase Claims of Ineffective Assistance of Counsel Standard of Review To successfully prove a claim of ineffective assistance of counsel, both prongs of the Strickland test must be satisfied as follows: First, the claimant must identify particular acts or omissions of the lawyer that are shown to be outside the broad range of reasonably competent performance under prevailing professional standards. Second, the clear, substantial deficiency shown must further be demonstrated to have so affected the fairness and reliability of the proceeding that confidence in the outcome is undermined. A court considering a claim of ineffectiveness of counsel need not make a specific ruling on the performance component of the test when it is clear that the prejudice component is not satisfied. Ferrell v. State, 29 So.3d 959, 969 (Fla.2010) (quoting Maxwell v. Wainwright, 490 So.2d 927, 932 (Fla.1986) (citations omitted)). Because ineffective assistance of counsel claims present mixed questions of fact and law, the Court employs a mixed standard of review, deferring to the circuit court’s factual findings that are supported by competent, substantial evidence, but reviewing the circuit court’s legal conclusions de novo. See Sochor v. State, 883 So.2d 766, 771-72 (Fla.2004). “Judicial scrutiny of counsel’s performance must be highly deferential” and there is a strong presumption that trial counsel’s performance was nót ineffective. Strickland, 466 U.S. at 689, 104 5.Ct. 2052. “A fair assessment of attorney performance requires that every effort be made to eliminate the distorting effects of hindsight, to reconstruct the circumstances of counsel’s challenged conduct, and to evaluate the conduct from counsel’s perspective at the time.” Id. “[Strategic decisions do not constitute ineffective assistance of counsel if alternative courses have been considered and rejected and counsel’s decision was reasonable under the norms of professional conduct.” Occhicone v. State, 768 So.2d 1037, 1048 (Fla.2000). The defendant carries the burden to “overcome the presumption that, under the circumstances, the challenged action ‘might be considered sound trial strategy.’ ” Strickland, 466 U.S. at 689, 104 S.Ct. 2052 (quoting Michel v. Louisiana, 350 U.S. 91, 101, 76 S.Ct. 158, 100 L.Ed. 83 (1955)). Under the second prong of Stnckland, the defendant must prove that “there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Hoskins v. State, 75 So.3d 250, 254 (Fla.2011) (quoting Strickland, 466 U.S. at 694, 104 S.Ct. 2052). A defendant need not show “‘that counsel’s deficient conduct more likely than not altered the outcome’ of his potential proceeding, but rather that he establish ‘a probability sufficient to undermine confidence in [that] outcome.’ ” Porter v. McCollum, 558 U.S. 30, 130 S.Ct. 447, 455-56, 175 L.Ed.2d 398 (2009) (quoting Strickland, 466 U.S. at 693-94, 104 S.Ct. 2052). As mentioned above, “when a defendant fails to make a showing as to one prong, it is not necessary to delve into whether he has made a showing as to the other prong.” Preston v. State, 970 So.2d 789, 803 (Fla.2007) (quoting Stewart v. State, 801 So.2d 59, 65 (Fla.2001)). With these principles in mind, we turn to Simmons’ claims of ineffective assistance of counsel in the guilt phase of his trial. A. Failure to Move to Suppress the Statement as Involuntary At his trial, the State introduced evidence of the interrogation of Simmons in which, after being advised of his Miranda rights and waiving them, he ultimately stated, “Well, if you found blood in my car, I must have did it.” This statement was given in the second part of the interrogation in response to a detective truthfully informing Simmons that blood had been found in his car. Prior to his trial, Simmons’ counsel filed a motion to suppress his statements to detectives on the ground that he did not accompany them voluntarily to the sheriff’s office and was illegally arrested without probable cause. The trial court denied the motion and on direct appeal we found no merit in the claim. See Simmons, 934 So.2d at 1113-14. Counsel did not move to suppress the statement on the ground that it was extracted from him involuntarily through coercion. Now, in his postconviction proceedings, Simmons contends that trial counsel was ineffective in not moving to suppress on the ground that the statement was the involuntary product of coercion. He contends there is a reasonable probability that his statement, “Well, I guess if you found blood in my car, I must have did it,” would have been suppressed if the motion had been made on the basis of coercion, thus changing the outcome of his capital trial. In support of his claim, Simmons contends that due to his communicative and intellectual limitations, coupled with coercive police tactics, his one-line incriminating statement should have been excluded as involuntary. Those portions of the interrogation cited as most coercive by Simmons are the following, which have been placed in context of their occurrence: MR. PERDUE [detective]:.... If I can say to the state attorney that Erie cooperated with us before we finished with that apartment over there, we might be able to get you some help. MR. ADAMS [detective]: (Inaudible) angry sometimes (inaudible) first degree murder (inaudible) electric chair, lethal injection (inaudible). THE DEFENDANT: I didn’t kill that lady (inaudible). I didn’t kill that damn lady. THE DEFENDANT: I didn’t kill her, man. MR. PERDUE: What did she do to make you mad then? THE DEFENDANT: (Inaudible) tried to help, give her a place to take a shower, let her fix something to eat. She didn’t even have a stove, she said. MR. ADAMS: (Inaudible). THE DEFENDANT: (Inaudible) didn’t do nothing, all I did was drop her off. I don’t care what witnesses say (inaudible). Later in the interview, the colloquy that can be described as the harshest portion of the interrogation occurred as follows: MR. PERDUE: See, things ain’t adding up, bro. I’m going to tell you like it is, okay, things ain’t (inaudible). THE DEFENDANT: Well, I don’t care [what you say]. MR. PERDUE: I [know you] don’t care what [I say]. I’m tired of messing around with you. You’ve got all this evidence [pointing toward you.] THE DEFENDANT: (Inaudible). MR. PERDUE: We’re fixing to dissect your apartment. We’re fixing to dissect your parent’s house. We’re going to dissect your car. You got your own friend calling here now telling me that at 9 o’clock Saturday night he talked to you on your own damn phone, and she’s with you at your apartment. You’re lying to us. I’m going to send you down the road for first degree murder [I’m going to get you a] lethal injection. THE DEFENDANT: (Inaudible). MR. PERDUE: — now is that what you want? THE DEFENDANT: (Inaudible). MR. PERDUE: I don’t want to see you die. Enough people have died. THE DEFENDANT: I ain’t killed that lady, man, I don’t give— MR. PERDUE: Bull— THE DEFENDANT: — (Inaudible). MR. PERDUE: — bull, you know who did it (inaudible). THE DEFENDANT: If I killed— MR. PERDUE: (Inaudible) killed at. THE DEFENDANT: I didn’t— MR. PERDUE: She was with you at 9 o’clock Saturday night, that was well past half time. I watched the freaking game. You’re lying, it’s showing you’re lying. Witnesses are showing you’re lying, son. We’re opening a door for you, the only door you’re going to get, come on. THE DEFENDANT: (Inaudible). MR. ADAMS: We are your only friends you got, your only friends. MR. PERDUE: And you’re lying to us. MR. ADAMS: (Inaudible). THE DEFENDANT: I ain’t kill that lady. MR. ADAMS: You killed her, Eric, was it accidentally or did you just frea-kin’ panic? I believe that’s probably what happened, but you killed her. MR. ADAMS: (Inaudible). Do you want to die? We don’t want to see you die. You’re a grown man, why don’t you fess up to it (inaudible). THE DEFENDANT: I didn’t kill that lady (inaudible). MR. PERDUE: That’s what you’re going to be saying when you’re laying there on that table and you got that IV stuck in (inaudible). THE DEFENDANT: (Inaudible) is this. I went out to my dad’s Monday. I seen the helicopter and everything flying. I watched the news. MR. ADAMS: How come you told (inaudible) you didn’t find out anything about that, you talked (inaudible) a fireman, that’s the first time you knew anything happened to her. I’m losing my patience— THE DEFENDANT: You better get out of my face like that, man, [because I ain’t did nothing.] MR. ADAMS: No, what did you say. THE DEFENDANT: I said I was on my way Monday and I seen helicopters. At the evidentiary hearing, trial counsel Janice Orr testified that after speaking with Simmons, she did not believe his statement that if there was blood in his car, he “must have did it” was a confession, but that it was a sarcastic, flippant remark. Professor Richard Leo, a sociologist and law professor with training in the psychology of police interrogation and false confessions, testified about the circumstances of Simmons’ interrogation which, in Professor Leo’s opinion, created a danger of a false confession. Professor Leo opined that Simmons’ incriminating statement was a “compliant false confession” given to put an end to the interrogation, although he also testified that he could not conclude whether Simmons’ confession was false. The postconviction court denied relief on this claim, concluding that trial counsel was not ineffective in failing to move to suppress the statement as coerced and that her decision to treat the statement as a sarcastic response to the detectives was not unreasonable. The postconviction court further found that the statement was not made in response to any allegedly coercive techniques. We do not reach the question of whether trial counsel was deficient for not moving to suppress on the ground that the incriminating statement was the product of a coercive interrogation because we conclude that Simmons has failed to meet his burden under the second prong of Strickland. See Preston, 970 So.2d at 803. Simmons has not demonstrated that, but for trial counsel’s alleged error, the result of the proceeding would in all probability be different; that is, he has not demonstrated a probability sufficient to undermine our confidence in the outcome of the guilt phase. Even absent Simmons’ statement, our confidence in the guilty verdict is not undermined in light of the remaining evidence supporting Simmons’ guilt: Mr. Rodriguez testified that Simmons was the last person seen with Tressler in the laundromat on the evening of December 1, 2001. Eyewitnesses then saw Tressler trying to escape Simmons’ car and screaming for help at the intersection of State Road 44 and County Road 437. Three eyewitnesses identified the car they saw on the night of December 1, 2001, as resembling a Chevrolet Corsica or Ford Taurus and possessing characteristics matching Simmons’ car. There was blood spatter in Simmons’ car and a large, degraded blood stain on the passenger seat. Tire track impressions taken from the area near where Tressler’s body was discovered matched the two rear tires of Simmons’ car, which were two different tire models. Simmons’ semen was found in Tressler’s vaginal washings. Dr. Gulino testified that Tressler’s autopsy revealed extensive injuries to her anus not consistent with consensual anal sex. In light of these facts and circumstances, we conclude that there is sufficient evidence to find Simmons guilty of kidnapping, sexual battery, and first-degree murder. Simmons, 934 So.2d at 1111-12. Simmons has not demonstrated a reasonable probability that absent trial counsel’s errors a different result would occur sufficient to undermine this Court’s confidence in the outcome. Because the prejudice prong of Strickland has not been proven, relief is denied on Simmons’ claim that trial counsel was ineffective for failing to move to suppress his incriminating statement on the grounds that it was coerced. We turn next to Simmons’ other contentions that trial counsel was ineffective in the guilt phase of the trial. B. Stipulation to Irrelevant Evidence and Failure to Argue Sexual Encounter Was Consensual Simmons next contends that trial counsel was ineffective in stipulating to the fact that vaginal washings from the victim contained Simmons’ semen. The stipulation, which was read twice to the jury, stated: Ladies and gentlemen, the parties have agreed and stipulated that an analysis of the vaginal washings from Ms. Tressler produced Mr. Simmons’s semen in her vagina. This evidence is offered for the sole purpose of establishing that Mr. Simmons and Ms. Tressler had a sexual encounter. It is not relevant to the sexual battery charge herein as that charge involves allegations of anal penetration and it is not to be considered by you in any way as to that charge. Additionally, Simmons contends that the error was compounded by trial counsel’s failure to present the testimony of Simmons’ neighbors that Simmons had a consensual sexual encounter on the day of the victim’s murder. Edwin T. Johnson testified at the evidentiary hearing that he and his wife Deborah were Simmons’ neighbors in an apartment building in Mt. Dora for several months in 2001. Johnson testified that on Saturday, December 1, 2001, he and his wife were on their own patio where they overheard Simmons and a woman having what sounded like consensual sex next door. They did not see the woman and did not observe them having sex. Deborah Johnson testified that she did see Simmons’ female companion at the apartment complex on December 1, 2001, around 4 p.m., and she identified a photograph of that woman, who was said to be Tressler. Mrs. Johnson testified that she does not remember speaking with trial counsel and that she never received a subpoena from anyone, although she and her husband were available to testify. At the evidentiary hearing, trial counsel Janice Orr explained her decision to stipulate to the semen found in the vaginal washings by noting that after she had unsuccessfully argued to exclude the semen evidence, she believed the stipulation would be less damaging than live testimony on the presence of the semen. The stipulation included the statement that the DNA was not relevant to the charge of sexual battery and, Orr testified, she believed that she had tried to include in the stipulation the fact that the sexual encounter was consensual, but ultimately was not successful. Regarding her failure to present evidence that the sexual encounter was consensual, trial counsel testified that Simmons told her he did not have sex with Tressler on the day of the murder. Thus, although she was aware that Simmons’ neighbors were prepared to testify that they heard Simmons having consensual sex with someone who was probably Tressler on December 1, 2001, Orr believed Simmons’ version of events and also believed that the neighbors’ testimony would not be helpful because they did not actually see anything. As noted earlier, there is a strong presumption that trial counsel’s performance was not ineffective. See Strickland, 466 U.S. at 689, 104 S.Ct. 2052. Trial counsel made a strategic decision that the stipulation to semen found in Tressler’s vagina would have less of an adverse impact upon the jury than extensive live testimony concerning the semen. On this point, Simmons has failed to prove that trial counsel’s performance was deficient. Additionally, trial counsel’s decision not to call Simmons’ neighbors to testify was also a strategic decision. Orr testified that she believed their testimony would not be very helpful and was in conflict with what Simmons had told her about his actions on that day. She testified that Simmons told her he was not having sex with Tressler that day, but that they were cleaning the porch. Orr believed the Johnsons were incorrect in their assumptions about what was occurring on the porch and decided not to present their testimony. Accordingly, trial counsel was not deficient for failing to call Simmons’ neighbors at trial. Even if counsel’s performance was deficient in either of these respects, Simmons has failed to demonstrate that absent counsel’s errors, there is a probability of a different result sufficient to undermine our confidence. If the stipulation had not been presented, the fact of Simmons’ semen in the victim’s vagina would have been admitted by way of expert testimony. Moreover, even if counsel had made clear in the stipulation that the sexual contact was consensual, and had presented the testimony of the Johnsons to establish that fact, evidence of consensual sex hours prior to the murder would not diminish the incriminating effect of the eyewitness testimony, evidence of Tressler’s blood found in Simmons’ vehicle, and evidence that his tires matched casts of those taken where Tres-sler’s body was found. Accordingly, Simmons is not entitled to relief on this claim. C. Failure to Present Expert Testimony on False Confessions Simmons next contends that trial counsel was ineffective for failing to present the testimony of an expert in false confessions at trial. Professor Leo testified at the evidentiary hearing that because Simmons had a low I.Q. and communicative difficulties, he was: (1) more vulnerable to pressure and likely to confess; (2) more likely to seek guidance from authority figures to mold his behavior; (3) more likely to be submissive; (4) more likely to avoid conflict; and (5) more likely to not understand the consequences of his actions. Although Professor Leo testified that Simmons’ incriminating statement was a “compliant false confession,” he also testified that he could not conclude whether Simmons’ confession was in fact false. The postconviction court in the instant case denied relief on this claim, concluding that Professor Leo’s opinion that the statement was a “compliant false confession” was not supported by the facts and that there was no nexus shown between any coercive tactics and Simmons’ final statement that he “must have did it.” The postconviction court also noted that had the expert testimony been offered at trial, it would have been excluded. Simmons now contends that his admission that if blood was found in his car, he “must have did it” would have had less significance to the jury had trial counsel presented this expert testimony on false confessions. However, we conclude that Simmons has failed to demonstrate ineffective assistance of counsel for failing to present an expert in false confessions at trial. Orr testified that she did not view the statement as a confession but as a sarcastic comment made in frustration and intended to terminate the interrogation. Further, Simmons has never testified that his incriminating statement was in fact false. Finally, even if Professor Leo had been presented at trial to testify that the circumstances of the interrogation could lead to a false confession, such would not have significantly diminished the incriminating effect of the other evidence. Simmons has not demonstrated that trial counsel was deficient in failing to present Professor Leo or a similar expert at trial; nor has he demonstrated a reasonable probability that, had trial counsel done so, the verdict would have been different, such a probability being one sufficient to undermine our confidence in the result. Accordingly, relief on this claim is denied. D. Failure to Present Terry Simmons’ Testimony at Trial Simmons also argues that trial counsel was ineffective in failing to call Simmons’ father, Terry Simmons, to testify that: (1) Simmons did not run from the officers, thus he did not have consciousness of guilt; (2) Tressler had loose bowels during Thanksgiving which may have been the source of DNA evidence in Simmons’ car; and (3) Tressler’s blood found in the car may have come from scratches obtained from helping Simmons move a bougainvillea bush with “ferocious thorns.” This argument is without merit. The decision not to call Terry Simmons at trial was a strategic one. “[Strategic decisions do not constitute ineffective assistance of counsel if alternative courses of conduct have been considered and rejected and counsel’s decision was reasonable under the norms of professional conduct.” Occhicone, 768 So.2d at 1048. First, both trial counsel Jeffery Pfister and Janice Orr testified that they did not call Terry Simmons as a witness because they were concerned about his prior felony conviction for manslaughter, which stemmed from a bar fight, and the possibility that the jury might believe that violence was an inherited family trait. Pfister testified that the decision was a judgment call based in part on a stipulation between the defense and the State that Simmons spent all of December 2, 2001, with his father. This December 2 date was significant because part of the defense at trial was to argue that Tressler was killed on December 2, 2001, and not December 1, 2001. Pfister further testified that they believed the stipulation would also prevent admission of evidence of Terry Simmons’ conviction. Accordingly, trial counsel was not deficient because the decision not to call Terry Simmons was reasonable under the circumstances. Moreover, failure to present Terry Simmons’ testimony was not prejudicial for several reasons. First, Simmons’ failure to run when the officers came to his father’s home looking for Simmons does not prove innocence. Second, Cathy Simmons, Simmons’ mother, had already testified that Tressler had loose bowels on Thanksgiving. Third, Terry Simmons testified at the evidentiary hearing that he did not see any scratches on Tressler, but did testify that Simmons asked for a Band-Aid for her. Simmons has not established the second prong of Strickland in that he has not shown that, but for counsels’ failure to present Terry Simmons’ testimony, there is a reasonable probability the outcome of the trial would have been different — that is, a probability sufficient to undermine this Court’s confidence in the outcome of the trial. Thus, relief is denied on this claim. E. Failure to Call Shirley Harness and Carrie Marie Petty to Testify; Failure to Adequately Question Jerry Linton In this claim of guilt phase ineffective assistance of counsel, Simmons contends that trial counsel’s failure to call Shirley Harness and Carrie Marie Petty, and failure to adequately question defense witness Jerry Linton at trial, constitutes ineffective assistance of counsel because they could have provided exculpatory information. Harness would have testified that there was no animosity between Simmons and Tressler, but that two brothers named Rodriguez, who frequented the laundromat where Tressler worked, hated Tressler and had threatened to kill her if she did not stop being a “snitch.” Carrie Marie Petty would have testified that she saw an individual named John Yohman with Tres-sler on four or five occasions and they seemed friendly. Yohman had provided a statement to police that he saw Tressler at the laundromat close to midnight on December 1, 2001, and that there was a white vehicle parked outside, although at the evidentiary hearing, Yohman denied having associated with or spoken to Tressler. Simmons contends that Petty’s testimony coupled with Yohman’s denials concerning her would have created reasonable doubt in the jurors’ minds. As to Jerry Linton, Simmons’ cousin, trial counsel presented his testimony at trial that he met Tressler at Simmons’ apartment in November about one week before the murder. At the evidentiary hearing, Linton testified that Tressler told him that her abusive ex-boyfriend was lurking around town, had beaten her to the point that she limped, and that she was on the run from him. Accordingly, Simmons contends that had trial counsel elicited this evidence at trial, it would have suggested to the jury that either Yohman or the abusive ex-boyfriend committed the murder, thus creating reasonable doubt concerning Simmons’ guilt. Trial counsel testified that she and her full-time investigator attempted unsuccessfully to locate witnesses Harness and Petty. At the evidentiary hearing, Harness admitted that she was living “on the run” during the time frame in which the murder took place and that she was moving from place to place. She also testified that she was using drugs and alcohol during that time period. Petty testified that she worked at a restaurant that was within 100 to 200 feet of the laundromat where Tressler worked, but stopped working at the restaurant one to two months after Tressler’s murder. Postconviction counsel did not provide evidence that the witnesses were actually available at the time of trial, and did not provide evidence of what efforts are normally used to locate an unavailable witness. “A defendant cannot establish ineffective assistance of counsel based on counsel’s failure to call a witness who is unavailable.” White v. State, 964 So.2d 1278, 1286 (Fla.2007); see also Evans v. State, 995 So.2d 938, 943 (Fla.2008) (finding that trial counsel was not ineffective for failing to call an unavailable witness at trial where reasonable efforts were made to find the witness). Accordingly, Simmons has failed to demonstrate trial counsel’s performance was deficient as to witnesses Harness and Petty. Trial counsel did present the testimony of Jerry Linton at trial. He testified that he met Tressler at Simmons’ apartment in November about one week before the murder. Simmons claims that trial counsel should have also questioned Linton about his conversation with Tressler in which she told him that a former ex-boyfriend or ex-husband pushed her off a horse and then either kicked her or punched her. Additionally, Linton could have testified that Tressler told him she left Marion County to get away from the individual. At the evidentiary hearing, Linton testified that he observed Tressler limping when he first met her in October. Linton testified that when he asked her if she had gotten hurt, Tressler told him how she had received the injuries. Linton, however, did not know when the injury occurred or when she left Marion County. Trial counsel Orr testified that she did not recall why she did not ask Linton at trial about the conversation he had with Tres-sler. The postconviction court denied the claim, concluding that the testimony would not have been admitted at trial because it was hearsay without any exception. We agree that this claim lacks merit because Linton’s hearsay testimony would likely have been found to be inadmissible. Trial counsel cannot be ineffective for failing to pursue meritless questions or arguments. See Owen v. State, 986 So.2d 534, 543 (Fla.2008) (citing Melendez v. State, 612 So.2d 1366, 1369 (Fla.1992)). Even if the evidence had been admitted at trial, Linton would not have been able to testify when the injury or violence occurred or whether Tressler still feared her former ex-boyfriend or ex-husband. Accordingly, Simmons has failed to demonstrate that trial counsel’s performance was deficient or that he was prejudiced by counsel’s deficiency, as required in Strickland. F. Mismanagement of DNA Expert Dr. James Blake At trial, in an apparent effort to cast doubt on the State’s DNA testing procedures, Simmons presented by telephone the testimony of Dr. James Blake, an expert in DNA analysis, who testified that he analyzed certain items of evidence for the defense. He also testified that he did not test several swabs sent to him because he observed no visible blood on them and because trial counsel had not requested they be tested. After the FDLE could not obtain a DNA profile from the presumptive blood stain on Simmons’ car seat cushion due to the degraded condition of the sample, the State submitted the seat cushion sample, along with a sample of Tres-sler’s mother’s blood, to a laboratory for mitochondrial DNA (mtDNA) sequencing. Brian Sloan, a forensic DNA analyst with Orchid Cellmark forensic DNA laboratory in Dallas, Texas, who performed the mtDNA sequence, explained that mtDNA is inherited maternally and that the mtDNA sequence is a better technique than the Short Tandem Repeat (STR) technique to use on degraded blood samples. See Simmons, 934 So.2d at 1108. Sloan compared the mtDNA extracted from Simmons’ car seat cushion to the mtDNA of Lee Daubanschmide, Tressler’s mother and found that each of the samples had an anomaly in the same place. He concluded that the two mtDNA sequences were consistent. In his opinion, Tressler’s mother or anyone maternally related to her cannot be excluded as contributing to the blood stain on the seat cushion from Simmons’ car. During cross-examination, Dr. Blake agreed that a mother’s mtDNA is maternally inherited and would have the same mitochondrial DNA sequence as her daughter. Simmons now claims, as he did before the postconviction court, that trial counsel’s failure to properly prepare Dr. Blake to testify and failure to present his testimony in person rather than by telephone constitutes ineffective assistance of counsel because any benefits from his testimony were diminished. Simmons also argues that Dr. Blake’s testimony that Tressler’s mother was a good source of mitochondrial DNA actually bolstered the State’s case. Further, Simmons contends that when trial counsel asked Dr. Blake about samples he never tested, this could have led the jury to believe that Simmons was hiding information. At the evidentiary hearing, trial counsel testified that she could not secure Dr. Blake’s presence at the trial because the defense could not afford to cover his expenses, although the costs of trial were paid by the State because Simmons was declared indigent by the trial court. She also testified that she would have preferred to have him testify in person rather than by telephone, although she believed his testimony at trial was helpful overall. The postconviction court denied relief on this claim, concluding that even if there was some confusion over Dr. Blake’s testing of the swabs, such does not reach the level of ineffective assistance of counsel. Dr. Blake’s admission on cross-examination that the victim’s mother was a good source of mtDNA was simply a statement of recognized scientific fact. We agree with the postconviction court that Dr. Blake’s testimony on cross-examination that Tressler’s mother was a good source of mitochondrial DNA was an acknowledgement of a fact and no amount of preparation could have changed Dr. Blake’s response to that particular question. Simmons does not make clear how having Dr. Blake testify by telephone because of a lack of funding constituted ineffective assistance on the part of trial counsel. Additionally, although trial counsel may have been confused about which samples she sent to Dr. Blake for testing, Simmons has not demonstrated that this simple mistake rises to the level of deficiency required to support a claim of ineffective assistance of counsel. Accordingly, because Simmons has failed to demonstrate that trial counsel’s performance was deficient in regard to Dr. Blake, and further fails to demonstrate how Simmons was prejudiced thereby, relief is denied on this claim. G. Mismanagement of Blood Stain Expert Stuart James Simmons further asserts that defense witness Stuart James, a forensic scientist and blood stain pattern analyst, was mismanaged or should not have been called as a witness because he did not support the defense proposition that the absence of a large amount of blood in Simmons’ vehicle indicated that Tressler was not killed in the vehicle. In addition, Simmons claims James’ testimony was harmful because he testified that the blood spatter evidence was speculative and that the absence of blood on a defendant’s person does not mean he is innocent. At the evidentiary hearing, trial counsel Orr testified that she discussed the case with James on numerous occasions. According to her testimony, Orr did not feel it necessary to spend a great deal of time preparing him for trial because they already spent a lot of time reviewing the case and because he was a well-known expert who had testified frequently. Trial counsel testified that when James began testifying, she thought he was confusing this case with another because his testimony was very different from their previous conversations. For instance, Orr testified that James previously told her that the absence of a large amount of blood definitively indicated that the murder had not taken place in Simmons’ car. At trial, James’ testimony was more tentative. James noted that he preferred to testify about blood stains he could see as opposed to testifying about the absence of blood stains, because the absence of blood could have several potential explanations. Additionally, he testified that he often tells defense attorneys that an absence of blood on the defendant’s clothes does not necessarily mean that the defendant is innocent. Nevertheless, because of the fairly limited blood stains and absence of more supporting evidence, he could not conclude that a beating, stabbing, or gunshot wound had occurred in the car. He also testified that, based on the injuries and the autopsy report, he could not draw the conclusion that the murder occurred inside the vehicle. Nor could he say whether Tressler was transported in the car after the wounds took place. Thus, some of James’ testimony was unanticipated by trial counsel. Although some of James’ testimony was unanticipated, Simmons failed to establish that this resulted from a lack of preparation. Trial counsel met with or discussed the evidence with James on numerous occasions. Moreover, Simmons has not shown that, absent trial counsel’s alleged errors, there is a reasonable probability that a different outcome would result, thus undermining this Court’s confidence. James’ testimony still allowed trial counsel to argue that Tressler was not killed, wounded, or transported while injured in the car because the “fairly limited” amount of blood stains was not sufficient for him to reach that conclusion. Because ineffective assistance of counsel has not been demonstrated in this claim, relief is denied. H. Failure to Discover and Present Testimony of John Fitzpatrick’s Involvement in the DNA Testing In his next claim, Simmons argues that trial counsel was ineffective in failing to investigate, discover, and introduce evidence regarding DNA expert John Fitzpatrick’s involvement in this case. Testimony presented at the evidentiary hearing showed that on January 12, 2002, Fitzpatrick, the Florida Department of Law Enforcement (FDLE) analyst who initially handled the forensic evidence in this case, altered the computer data for a DNA proficiency test he was given beginning on December 4, 2001. Fitzpatrick altered the data on the sample sheet in the computer in an effort to provide correct labeling information for two test samples which he had erroneously switched during one of the steps in his proficiency examination. Fitzpatrick did not advise his supervisors of his testing error or of his attempt to correct it in the computer. After his computer alteration was discovered on January 24, 2002, Fitzpatrick was asked to resign in lieu of being fired. Robyn Rags-dale, FDLE laboratory analyst and statewide technical leader for biology in 2001, testified that FDLE conducted a quality assurance review of Fitzpatrick’s eighteen open cases and his thirty-four recently completed cases and issued a report on February 2, 2002. This quality review disclosed no additional instances of mislabeling of samples or switching of samples during testing. Fitzpatrick did not testify at trial and all the evidence was retested by Shawn Johnson, the FDLE analyst who did testify at trial as to DNA evidence, the rape kit, and other swabs and slides submitted as part of the investigation. Simmons now contends that trial counsel was ineffective in her investigation and failure to present evidence concerning Fitzpatrick. Simmons argues that the State’s case would have been severely weakened had the jury been informed of Fitzpatrick’s involvement because trial counsel could have argued to the jury that the blood evidence was tainted, could have been contaminated, and was falsified. At the evidentiary hearing, trial counsel testified that she was aware of the problem with Fitzpatrick and agreed that her investigator had prepared a spreadsheet summarizing all of the physical evidence in the case. The spreadsheet noted that there were three pieces of physical evidence handled by Fitzpatrick. The files that trial counsel received from the public defender’s office also contained information regarding Fitzpatrick. Accordingly, Simmons has failed to demonstrate that trial counsel’s performance was deficient as it relates to failure to discover or investigate Fitzpatrick’s involvement in the case. We also disagree that trial counsel was ineffective in failing to present evidence concerning Fitzpatrick at trial in order to speculate to the jury that the DNA evidence was contaminated or falsified. The evidence presented at the evidentiary hearing established that Shawn Johnson retested all the items handled by Fitzpatrick, and Simmons presented no evidence at the eviden-tiary hearing that the forensic evidence in this case was contaminated, tainted, or falsified. Thus, we conclude that trial counsel was not ineffective in failing to present evidence concerning Fitzpatrick’s initial involvement with the DNA analysis. We also conclude that Simmons has failed to show a reasonable probability that, but for counsel’s failure to present evidence concerning Fitzpatrick, the outcome of the trial would have been different — a reasonable probability being one sufficient to undermine this Court’s confidence in the outcome of the trial— based on Fitzpatrick’s alteration of the proficiency test data, his resignation, or his involvement with the DNA evidence in this case. Evidence presented at the eviden-tiary hearing demonstrated that Fitzpatrick initially handled the forensic evidence in this case and, before he resigned for falsifying information on his proficiency test, he had tested most, but not all, of the DNA evidence. Shawn Johnson testified at the evidentiary hearing that he retested all the items tested by Fitzpatrick, and that the blood stains in Simmons’ car were submitted to FDLE after Fitzpatrick left the agency. Simmons has not demonstrated that Johnson’s test results are inaccurate or incorrect. The argument proffered by Simmons that the jury could believe the DNA evidence tested by Johnson was tainted has no basis in fact and is mere speculation. Accordingly, Simmons cannot demonstrate that, absent trial counsel’s alleged errors in regard to Fitzpatrick, there is a probability of a different result sufficient to undermine this Court’s confidence in the outcome of the trial. For these reasons, relief is denied on this claim. II. Guilt Phase Brady and Giglio Claims Simmons raises several claims in this section. First, he contends that the State willfully withheld exculpatory and impeachment evidence concerning John Fitzpatrick in violation of Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963). He also contends that the State presented, or failed to correct, false or misleading testimony from Sherri Renfro and Jose Rodriguez in violation of Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972). Standard of Review Claims under both Brady and Giglio present mixed questions of law and fact. See Sochor, 883 So.2d at 785. This Court defers to the lower court’s findings of fact if they are supported by competent, substantial evidence. See Hurst v. State, 18 So.3d 975, 988 (Fla.2009); see also Taylor v. State, 62 So.3d 1101, 1114 (Fla.2011) (noting that “[questions of whether evidence is exculpatory or impeaching and whether the State suppressed evidence are questions of fact, and the trial court’s determinations of such questions will not be disturbed if they are supported by competent, substantial evidence”). This Court reviews the trial court’s application of the law to the facts de novo. Hurst, 18 So.3d at 988. To establish a Giglio violation, the defendant must show that: (1) the prosecutor presented or failed to correct false testimony; (2) the prosecutor knew the testimony was false; and (3) the evidence was material. See Tompkins v. State, 994 So.2d 1072, 1091 (Fla.2008). “If there is a reasonable possibility that the false testimony may have affected the judgment of the jury, a new trial is required.” Craig v. State, 685 So.2d 1224, 1226 (Fla.1996). “In order to establish a Brady violation, the defendant must demonstrate that (1) favorable evidence, either exculpatory or impeaching, (2) was willfully or inadvertently suppressed by the State, and (3) because the evidence was material, the defendant was prejudiced.” Mungin v. State, 79 So.3d 726, 734 (Fla.2011). The materiality prong is met where the defendant demonstrates a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different, with a reasonable probability being one that is sufficient to undermine confidence in the outcome. Id. We first discuss the alleged Brady violation concerning John Fitzpatrick. Simmons contends that the State committed a Brady violation when it failed to provide the defense with evidence of Fitzpatrick’s misconduct on his proficiency examination. Trial counsel Janice Orr testified at the evidentiary hearing that she was aware that Fitzpatrick had been involved as an analyst in the case and further, that she had access to the public defender’s files which included information about Fitzpatrick. The trial court also found based on competent, substantial evidence that the prosecutor had informed Simmons’ public defender that Fitzpatrick was the analyst who initially worked on the DNA samples in Simmons’ case. Orr testified that she did not recall whether Fitzpatrick was fired, but when the case went to trial, she knew there had been a problem with his work. Trial counsel also agreed that her files contained a spreadsheet prepared by her investigator at the time of trial which indicated Fitzpatrick had worked on some of the evidence in the case and that he was fired. Trial counsel testified at the evidentiary hearing that she did not pursue the Fitzpatrick proficiency testing problem and his leaving FDLE because “it became a nonissue.” Shawn Johnson, another FDLE DNA analyst, retested all the evidence after Fitzpatrick resigned and the results were consistent with Fitzpatrick’s. Simmons is correct that when he was represented by a public defender, the trial court did enter an order compelling disclosure of a number of items relating to the forensic testing, including all proficiency test results of any analyst who performed work in the case. Fitzpatrick’s proficiency testing information and a document prepared by Fitzpatrick appearing to be a report on the testing he did in this case were not specifically provided. Whether or not the State should have disclosed the Fitzpatrick draft report and the material concerning his proficiency testing, it is clear that Simmons’ subsequent trial counsel, Janice Orr, was well aware that there had been a problem with Fitzpatrick, and knew that he had been the initial examiner in the case and, she believed, that he was fired. “Although the ‘due diligence’ requirement is absent from the Supreme Court’s most recent formulation of the Brady test, it continues to follow that a Brady claim cannot stand if a defendant knew of the evidence allegedly withheld or had possession of it, simply because the evidence cannot then be found to have been withheld from the defendant.” Oc-chicone, 768 So.2d at 1042. Even if the specifics of the proficiency testing problem were not provided to counsel, Simmons cannot establish that the evidence was exculpatory or impeachment evidence nor can he establish that the evidence was material and thus prejudicial. Fitzpatrick’s conduct on the proficiency test was not exculpatory in the case, nor did his lack of proficiency and lapse in integrity impeach the DNA and other forensic results that were testified to at trial by Johnson, who independently retested the evidence. There was no indication that any of the evidence was tainted by Fitzpatrick during the investigation. Finally, even if the evidence of Fitzpatrick’s misconduct and the FDLE’s handling of that misconduct had been introduced, there is no reasonable probability — measured by whether our confidence in the outcome is impaired or undermined — that the proficiency testing evidence would have resulted in a different verdict in the case. Thus, relief is denied on this Brady claim. We turn next to Simmons’ Giglio claims. Simmons also contends that the State willfully presented false testimony or failed to correct testimony of Sherri Ren-fro and Jose Rodriguez, which the prosecutor learned was false. During Renfro’s testimony at trial in September 2003, she acknowledged that she was placed on probation in April 2003 for a conviction of dealing in stolen property. She testified at trial, however, that she was not “in trouble with her probation officer” or “at risk of going to jail.” At the evidentiary hearing, Renfro testified that at the time of the trial, she was fearful of violating her probation because she did not have a stable residence or a job, and was pregnant. Renfro was asked at the evidentiary hearing about a May 13, 2003, report of her probation officer, in which the probation officer stated that she informed Renfro she was currently in violation of her probation and directed her to report for transfer papers to change her probation to Lake County. Renfro testified that she did not feel that she was in violation because she had contacted her probation officer to get transfer papers and had been honest with her. On June 10, 2003, the prosecutor, William Gross, called and left a message at the probation office notifying them that Renfro had moved to Lake County. Renfro testified that she did not recall being in violation of probation, but recalled the transfer; and said that she was not using the state attorney’s office to try to avoid the risk of being charged with a violation of probation. Renfro agreed that on June 3, 2003, she asked for help from the state attorney’s office to get into a women’s shelter because she was pregnant and homeless. A state attorney investigator made an unsuccessful telephone call to attempt to locate a shelter bed for Renfro. On July 22, 2003, Renfro was given a suspended twenty-day jail sentence on the condition that she complete her probation requirements by September 22, 2003. The prosecutor wrote a letter to Judge Boylston dated September 25, 2003, which was six days after Simmons’ trial ended, which advised the court that Renfro had been unable to pay fines and costs by September 22, 2003, because she could not find work due to her pregnancy. The prosecutor testified at the evidentiary hearing that at the time of trial, he did not know that Renfro owed any money or was under any specific obligations imposed by Judge Boylston. He also testified that he never asked a probation officer to give Renfro any kind of special treatment and that he kept apprised of her location and whether she had a place to stay so he would know where to locate her at the time of trial. Renfro also testified at the evidentiary hearing that she violated her probation by possession of drugs several months after Simmons’ trial. The postconviction court found that the State had not knowingly presented false testimony at trial. The court further concluded that because Renfro’s testimony at the evidentiary hearing was inconsistent regarding whether at the time of trial she was afraid that she would be charged with violating probation, it would assume for the purpose of the ruling that Renfro lied at trial. Even so, the postconviction court concluded that the false testimony was not material because a second witness corroborated her eyewitness testimony and because she gave her witness statements to police well before any incentive to lie arose. We agree that Simmons failed to establish that the State knowingly presented or failed to correct any false testimony at trial and that, even if Renfro’s testimony on the question was false, prejudice has not been established. Thus, relief on this aspect of Simmons’ Giglio claim is denied. Simmons also contends that the state presented false testimony of Jose Rodriguez, who testified at trial that he knew Tressler from the laundromat and that he saw Simmons with Tressler on the night of December 1, 2001. Rodriguez was arrested on unrelated charges on December 2, 2001, prior to his December 5 interview by police in which Rodriguez was shown a photographic lineup and picked out a photograph of a person who resembled Simmons. Rodriguez testified at trial that the State had done nothing to reduce his sentence or provide him with any preferential treatment, although he did testify that the police contacted his bondsman to try to help him get out of jail. The police did not give him any money or post bond for him. The postconviction court held that Rodriguez d
