A man convicted of killing a traveling salesman during a robbery is set to become Florida’s first execution of 2026 under a death warrant signed Friday by Republican Gov. Ron DeSantis, who signed off on a record 19 executions last year.
Ronald Palmer Heath, 64, is scheduled to die by lethal injection Feb. 10 at Florida State Prison. DeSantis oversaw more executions in a single year in 2025 than any other Florida governor since the death penalty was reinstated in 1976. The previous record was set in 2014 with eight executions.
Heath was convicted of first-degree murder, robbery with a death weapon and multiple forgery charges in 1990.
According to court records, Heath and his brother, Kenneth Heath, met traveling salesman Michael Sheridan at a Gainesville bar in May 1989. After hanging out at the bar for some time, the three men agreed to go somewhere else to smoke marijuana.
At some point, the brothers plotted to rob the other man, investigators said. Ronald Heath drove the group to a remote area, where Kenneth Heath pulled a handgun on Sheridan. The man initially refused to give the brothers anything, and Kenneth Heath shot Sheridan in the chest.
As Sheridan emptied his pockets, Ronald Heath began kicking the man and stabbing him with a hunting knife, prosecutors said. Kenneth Heath then shot Sheridan twice in the head.
The brothers dumped Sheridan’s body in a wooded area and returned to the Gainesville bar to take items from his rental car. The brothers made multiple purchases with Sheridan’s credit cards the next day at a Gainesville mall.
Ronald Heath was arrested several weeks later at his Douglas, Georgia, home after investigators connected him to the stolen credit cards. Officers recovered clothing purchased with the stolen cards, as well as Sheridan’s watch, according to court records.
Kenneth Heath was also charged with Sheridan’s murder, but he was sentenced to life in prison as part of a plea agreement.
Attorneys for Ronald Heath are expected to file appeals to the Florida Supreme Court and the U.S. Supreme Court.
A total of 47 people were executed in the U.S. in 2025. Florida led the way with a flurry of death warrants signed by DeSantis. The state’s final execution of 2025 was the Dec. 18 lethal injection of Frank Athen Walls, who was convicted of fatally shooting a man and his girlfriend during a home invasion robbery.
