The Case of Robert and Tayten Baker

On August 26, 2020, brothers Robert Baker, 12, and Tayten Baker, 14, were brutally murdered inside their family's home in Melrose, Florida. Mark Howard Wilson Jr., the boyfriend of their aunt, had been living in an outbuilding on the family property. Wilson entered the house before dawn and killed both boys with a hammer and fillet knife. He later confessed to the murders and was sentenced to death.

Robert Baker, 12, and his older brother Tayten Baker, 14, lived with their mother, Sarah Baker, and other family members in Melrose, Putnam County, Florida. Five days before the murders, Mark Howard Wilson Jr. moved onto the Baker property with his girlfriend, Cynthia "Cindy" Guinan, who was Sarah Baker's sister, and their 14-month-old daughter. Wilson and Guinan stayed in a shed on the property. Because the shed did not have a working bathroom, Wilson had access to the main house to use the bathroom and kitchen and to do laundry. The family had no apparent history of serious conflict with Wilson that would have suggested the violence that followed. On the night of August 25, 2020, Tayten slept in the pool-table room while Robert slept in the living room. Wilson later told investigators that he believed the boys had been abusing his young daughter. The investigation found no evidence that either boy had abused the child.

In the early morning hours of August 26, Sarah Baker saw Wilson outside the house sharpening a fillet knife. Later that morning, Sarah discovered that both of her sons had been murdered. Robert had suffered multiple blows to the head from a hammer and a severe incised wound across his neck. The wound was so deep that it transected major blood vessels, the larynx and supporting muscles. Tayten had suffered multiple blows to the head and extensive sharp-force injuries to his neck. Investigators determined that he had been alive during at least part of the attack and had attempted to defend himself. A bloody handprint belonging to Tayten was found on a wall near his body. The medical examiner determined that the cause of death for both brothers was sharp-force injuries to the neck and blunt-force trauma to the head. Investigators recovered a hammer and a fillet knife associated with the murders. DNA evidence was particularly significant. Tayten's blood and DNA were found on Wilson's hammer, while DNA from both Robert and Tayten was found on Wilson's fillet knife. Wilson's blood-stained black hooded sweatshirt also contained DNA belonging to both boys.

Wilson initially became a suspect because of his proximity to the victims and evidence recovered from the scene. He subsequently confessed to his mother, telling her that he had killed the boys. His mother contacted law enforcement and agreed to participate in a recorded conversation with Wilson while wearing a wire. During the recorded conversation, Wilson made admissions concerning the murders. He was arrested and subsequently interviewed by investigators, to whom he also admitted killing Robert and Tayten. Wilson claimed that he believed the boys posed a threat to his daughter because he believed they had abused her. Investigators found no evidence supporting that belief. The physical evidence independently connected Wilson to the murders. His hammer contained Tayten's DNA, his fillet knife contained DNA from both boys, and his sweatshirt contained DNA from both victims. The prosecution ultimately established that Wilson had entered the house armed and deliberately attacked the brothers.

Wilson was convicted in October 2022 of two counts of first-degree murder, as well as burglary while armed. During the penalty phase, the jury unanimously found the aggravating circumstances sufficient to warrant death and unanimously recommended the death penalty for both murders. On January 27, 2023, Wilson was sentenced to death for the murders of Robert and Tayten. He also received a consecutive life sentence for armed burglary. The Florida Supreme Court affirmed his convictions and death sentences on May 22, 2025. Wilson subsequently petitioned the U.S. Supreme Court, which denied his petition for certiorari in November 2025.

The murders were particularly significant because Wilson was living on the family's property and had access to the home through his relationship with the boys' aunt. The court found that the murders were planned and deliberately carried out, rejecting any suggestion that the killings were justified by Wilson's belief that the boys had harmed his daughter.
