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.

I

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

1. We have jurisdiction. See art. V, § 3(b)(1), (9), Fla. Const.

-2- 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

2. Priscilla and her two children spent the previous night with relatives.

-3- 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).

-4- 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

-5- 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

4. Modlin lived near the Kaczmar home and spent time with Kaczmar the day before the murder.

-6- 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.
