GROSSHANS, J.

The parties in this postconviction case appeal the circuit court’s order that vacated Leo Louis Kaczmar, III’s death sentence

but upheld his first-degree murder conviction. 1 For the reasons given below, we reverse the grant of penalty-phase relief. We affirm in all other respects. We also deny Kaczmar’s petition for habeas corpus relief.

One December morning in 2008, Eva Mitchell and her husband observed a home on fire in Green Cove Springs, Florida. Eva called 911, while her husband ran up to the home, kicked open the back door, and shouted to determine if anyone was inside. No one responded.

Law enforcement and firefighters soon arrived at the home.

They learned that in the days leading up to the fire, the home had been occupied by Kaczmar, his wife and children, his uncle, and his father’s girlfriend—Maria Ruiz. Once the fire was contained, law enforcement located a burned and bloodied body near the kitchen. The officers would soon discover it was the body of Maria Ruiz.

This discovery gave rise to an investigation, with canvassing efforts being one of the initial steps. From discussions with a

neighbor—Julia Ferrell—law enforcement learned that a heated argument had occurred at the Kaczmar home in the early morning hours before the fire. Ferrell indicated that Kaczmar’s voice was discernable during the argument.

Meanwhile, a fire investigator took steps to determine the cause and origin of the fire. To this end, the investigator identified and collected six areas of fire debris, five of which would later test positive for the presence of gasoline.

As the initial investigation was taking shape, Kaczmar’s wife Priscilla arrived at the home and called Kaczmar. 2 During the conversation, she passed the phone to Officer John Parker who asked Kaczmar to come to the home. Kaczmar complied.

Upon arriving at the home, Kaczmar showed Officer Parker a receipt indicating that Kaczmar had purchased gas that morning near Jacksonville. Kaczmar told Officer Parker that he had been fishing in the Jacksonville area.

Later that day, officers asked that Kaczmar report to a nearby police station in order to discuss matters relating to the fire and the

discovery of Ruiz’s body. Kaczmar agreed and was driven to the station by his mother and stepfather. At the outset of the interview, Detective Charlie Sharman advised Kaczmar of his constitutional rights, which Kaczmar acknowledged by signing a form. 3 In the exchange that followed, Kaczmar generally denied involvement in the arson and other wrongdoing. Although he repeated his earlier story that he had been fishing in Jacksonville, he acknowledged being alone in the home with Ruiz from roughly 11:00 p.m. to 2:00 a.m.—just hours before the fire.

Midway through the interview, Detective Sharman pressed Kaczmar about some of his injuries and the condition of his clothing. Kaczmar responded that he wanted an attorney if that line of questioning continued. However, Kaczmar promptly reengaged Detective Sharman in discussion. In response, Detective Sharman reminded Kaczmar that he had the right to a lawyer during the interview. Not invoking that right, Kaczmar returned to talking about matters pertaining to the active police investigation.

3. See Miranda v. Arizona, 384 U.S. 436, 467 (1966) (requiring police to advise suspects in custody of certain things—including the right to silence and the presence of a lawyer—prior to interrogation).

Kaczmar ultimately left certain articles of clothing at the station, including a sock that he smeared his own blood on during a break in the interview.

Weeks later, after law enforcement uncovered more evidence implicating Kaczmar (including that he purchased a small amount of gasoline from a nearby gas station moments before the fire was observed), a grand jury indicted him on charges of first-degree murder, attempted sexual battery, and arson. The State gave notice that it sought the death penalty for the murder.

Meanwhile, Kaczmar’s post-indictment conduct and conversations were brought to the prosecutor’s attention and became sources of evidence at trial. After his arrest, Kaczmar was confined in the Clay County Jail, where he spent significant time with William Filancia, a fellow inmate who was frequently housed with Kaczmar. At some point after Kaczmar started talking about his case, Filancia reached out to his attorney, Richard Kuritz. Kuritz, in turn, spoke with the prosecutor and Detective Sharman, setting up a meeting with them.

Eventually, Detective Sharman enlisted the services of an undercover officer, Detective Charles Humphrey, who agreed to

portray himself as “Carlos,” a friend of Filancia. Detective Sharman gave Detective Humphrey a map that Kaczmar had drawn, which showed the way to Christopher Ryan Modlin’s home. 4 Soon after being given the map, Detective Humphrey began visiting Kaczmar at the jail. During the four visits, the two discussed (1) putting gasoline-soaked clothes at or under Modlin’s home in an effort to frame him, (2) intimidating witnesses to come forward in support of Kaczmar, and (3) arranging to have Kaczmar’s wife Priscilla pay “Carlos” $300 for these purported services.

Several months after Detective Humphrey’s last jail visit, Kaczmar’s case went to trial. The State called numerous witnesses, including the medical examiner (Dr. Jesse Giles), two DNA experts, Julia Ferrell, Kaczmar’s wife, Detectives Sharman and Humphrey, and a fire investigator and analyst. Additionally, the State presented physical evidence tying Kaczmar to the crime scene. This included photographic and video evidence showing Kaczmar purchasing gasoline minutes before the fire. The State also played recordings of Kaczmar’s interview with Detective Sharman and

three of his conversations with Detective Humphrey. Following the State’s case, Kaczmar asked for a judgment of acquittal on all charges, which the trial court denied.

As for the defense case, Kaczmar’s counsel called one witness, Detective Michael Goldner, who testified about his search of Kaczmar’s truck. According to the detective, he observed nondescript stains and collected evidence of them. But neither he nor other law enforcement sought to have the stain-related evidence tested.

Ultimately, the jury found Kaczmar guilty on all charges. And following the penalty phase, it recommended a sentence of death by a vote of 11 to 1. Accepting that recommendation, the court sentenced Kaczmar to death.

Kaczmar appealed, raising nine issues for our review.

See Kaczmar v. State (Kaczmar I), 104 So. 3d 990, 998 (Fla. 2012). We concluded that he had failed to show reversible error in connection with his first-degree murder conviction. Id. at 998- 1006. But as for the penalty phase, we found that the State had not proven three of the four aggravators and determined that such error was not harmless. Id. at 1007-08. Consequently, we reversed

Kaczmar’s death sentence, remanding for a new penalty phase. Id. at 1008.

On remand, Kaczmar waived his right to present mitigation, doing so against his counsel’s advice. See Kaczmar v. State (Kaczmar II), 228 So. 3d 1, 6 (Fla. 2017). Prior to jury selection, the trial court gave the following preliminary statement to the jury pool:

Good morning, ladies and gentlemen. My name is William Wilkes, and I’m the Judge that will be handling this case.

This case has a little history to it so let me explain your duty today. It’s different than most trials we ever have.
