Curtis Windom, 59, was executed by lethal injection in Florida on Thursday for the 1992 murders of three people.
His death marks the 11th execution in the state this year.
Windom was convicted of killing Johnnie Lee over a $2,000 gambling debt, then fatally shooting his girlfriend, Valerie Davis, and her mother, Mary Lubin.
According to reports, he shot Davis at her apartment and Lubin while she was stopped at a nearby intersection.
The execution was carried out at 6:17 p.m. local time at Florida State Prison. His final words were reported as unintelligible by media witnesses.
The U.S Supreme Court had rejected his final appeal a day earlier.
His attorneys had argued that his original legal representation was unqualified.
Despite his conviction, some family members of the victims opposed the execution.
In a statement released by Floridians for Alternatives to the Death Penalty, they expressed disappointment with the state’s decision, calling the process a “dog-and-pony show.”
The statement also revealed they had maintained contact with Windom over the years and had forgiven him.
Windom’s case is part of a broader rise in executions across the U.S. this year, with 30 people executed so far, the highest number since 2014.
Florida leads with 11 executions, followed by Texas and South Carolina with four each.
Most executions in 2025 have been carried out via lethal injection.
However, two used firing squads and three involved nitrogen hypoxia, a controversial method condemned by UN experts as cruel and inhumane.
The death penalty remains a divisive issue in the U.S. It has been abolished in 23 states, while three others; California, Oregon and Pennsylvania have official moratoriums.
Former President Donald Trump, a vocal supporter of capital punishment, recently stated he would seek the death penalty for murder cases in Washington, D.C as part of a broader anti-crime agenda.
