MARK H. WILSON, Appellant,

vs.

STATE OF FLORIDA, Appellee.

May 22, 2025

PER CURIAM.

Mark Howard Wilson appeals his convictions and sentences of

death for the first-degree murders of his girlfriend’s young nephews

in 2020. We have jurisdiction. See art. V, § 3(b)(1), Fla. Const. For

the reasons explained, we affirm.

I. BACKGROUND

On August 26, 2020, Sarah Baker awoke to find her sons,

twelve-year-old Robert and fourteen-year-old Tayten, brutally

murdered in her home. Their heads were beaten with a hammer

and their throats cut. Appellant Mark Wilson was the boyfriend of Sarah’s sister, Cynthia Guinan (Cindy). Five days before the

murders, Wilson, Cindy, and their fourteen-month-old daughter,

K.W., moved into a shed on the Bakers’ property at Sarah’s

insistence, after Sarah learned that their rental was infested with

fleas and had no power, and they had no food and were smoking

marijuana in the house with K.W. present.

Wilson, Cindy, and K.W. moved to the Bakers’ property on

August 21, 2020. Sarah lived there with her husband, Chad, the

victims, and her other son, who was four years old at the time. The

shed did not have a working bathroom, so Wilson had access to the

Bakers’ house to use the bathroom and kitchen, and to do laundry.

Sarah said that nothing was out of the ordinary on August 25,

2020, which was the day before the murders. Cindy had a doctor’s

appointment scheduled for the morning of the 26th to confirm a

positive home pregnancy test, and Sarah gave her and Wilson ten

dollars for gas to get to the appointment. That night, Tayten slept

in the “pool table room” and Robert slept in the living room.

Around 2 or 3 a.m. on the morning of August 26, Sarah saw Wilson

when she went outside to smoke. Wilson was on the porch

-2- sharpening his knife and was acting normal and did not seem

impaired. Sarah went to bed soon after.

When Sarah woke later that morning, she saw blood on the

floor as she entered the pool table room. When she removed

Tayten’s blanket, she saw that he was covered in blood. His throat

appeared to be severed to the bone, and he had no pulse. Tayten

borrowed Sarah’s phone the previous night, and she could not find

it so she ran to Cindy and Wilson’s door but they were not there.

Sarah then ran back to the house, screaming at Robert to call 911,

but when she removed Robert’s blanket, she saw that he too was

covered in blood. Sarah then drove to her father’s house on the

next street to call for help.

Investigators found a hammer and a fillet knife under a sink in

another detached building on the property. Both appeared to have

blood on them and were wrapped in placemats. Blood-soaked

paper towels were found in the trash outside. A note that was

handwritten by Wilson was also found. The note read:

Honey, if I could find words for what you do to make me completely whole, I would. I get so frustrated, baby, cause most of the time I come off as angry or confrontational, but you have to understand that you [sic] and [K.W.] by my side, I am way more than ordinary.

-3- I can’t even try to imagine life without you and her. I can’t lose you two. [K.W.] is so extraordinary. She really is our greatest achievement. Please promise me that she will always know that her dada is a soldier and that he loved you from day one and will always love you both until the end of time.

Wilson returned to the Baker home after Cindy’s doctor

appointment. He was informed about the murders and gave three

brief interviews to Putnam County Sheriff’s Detective Jacob

Higginbotham at the scene. In all three of these interactions,

Wilson was responsive and did not appear to be impaired in any

way.

The day after the murders, Wilson’s mother, Chrisy Adkins,

told Wilson that he needed to cooperate with law enforcement and

take a polygraph to clear his name. Wilson said he could not do

that. Adkins asked him, “[D]id you hurt those babies?” to which

Wilson responded, “Yes, Mom, I did it.” Shortly after the

confession, Adkins drove to the sheriff’s office and informed law

enforcement that she believed Wilson was responsible for the

murders. She agreed to have another conversation with Wilson

about the murders while wearing a wire.

-4- The recorded conversation between Adkins and Wilson took

place in Adkins’s car. Wilson said that he and Cindy had made a

plan in which he would kill Robert and Tayten and Cindy would kill

Sarah and Sarah’s four-year-old son. After hearing Wilson’s

admissions on the wire, law enforcement conducted a traffic stop on

the vehicle and arrested Wilson. Wilson was transported to the

sheriff’s office and agreed to speak with law enforcement and to

provide a DNA sample.

Wilson began by detailing what he and Cindy did on the

morning of August 26, which included trips to Cindy’s parents’

home, a convenience store, the doctor’s office, and their prior

residence to feed his dog. Wilson could recall in detail all the

specific roads he and Cindy traveled when making those stops.

Wilson also described having sex with Cindy early that morning,

and he recalled the medication she took for an upset stomach.

Wilson initially denied involvement in the murders, but after

learning about the recorded conversation with his mother and being

told that Cindy had implicated him and revealed their murderous

plan, he admitted using his hammer to hit each of the boys multiple

times and cutting their throats with a fillet knife. He claimed to

-5- believe that the boys were physically and sexually abusing K.W. and

said the boys were probably having sex with Cindy too, although he

later backtracked on that allegation. 1 Wilson also said that he

thought Cindy was covering up the boys’ sexual abuse of K.W.

Wilson agreed that his motive for killing the boys was “pretty much”

because he felt like they were abusing and hurting Cindy and K.W.

He also said that Cindy was messing with his head and that she

indirectly told him to kill the boys. Wilson said that he and Cindy

were using methamphetamine on the day of the murders and that

he had been awake for two to three days.

Wilson said the murders occurred in the morning on August

26 after he and Cindy returned from picking up coffee around 7:00

a.m. but before they left for the doctor appointment at 9:00 a.m. He

said Cindy was right outside while he was in the house killing the

boys and that she saw them after they were dead. Both boys were

sleeping when Wilson began the attack. Wilson claimed that he

blacked out during the attack, that his memory was “foggy,” and

1. Law enforcement investigated the allegations regarding the boys and Cindy and K.W. and found no evidence to support them.

-6- that he recalled “bits and pieces.” Wilson admitted to being “cold

and emotionless”—as opposed to upset or in a rage—while he was

committing the murders.

FDLE tested evidence for fingerprints, DNA, and blood. A

bloody handprint found on the wall near Tayten’s body was

identified as Tayten’s. Tayten’s blood and DNA were on Wilson’s

hammer. DNA matching both Tayten and Robert was found on

Wilson’s fillet knife. The blood-stained, black, hooded sweatshirt
