On Thursday, Florida carried out the execution of a man convicted of the fatal shooting of two individuals during a home invasion robbery. This marked the 19th execution in the state for the year.

Frank Athen Walls, aged 58, was administered a lethal injection at approximately 6 p.m. at Florida State Prison located near Starke. He was declared dead at 6:11 p.m. Walls had been sentenced to death in 1988 for his involvement in two murders, as well as charges of kidnapping, burglary, and theft.

Initially, the Florida Supreme Court overturned his conviction, mandating a retrial. However, in 1992, Walls was once again found guilty and sentenced to death.

According to the Associated Press, at precisely 6 p.m., the curtain to the execution chamber was raised. Walls lay strapped to a gurney, draped mostly under a blanket, with his left arm extended for the IV insertion. A Catholic priest sat at the gurney’s foot, extending his right hand toward Walls’ lower leg.

Following rulings from both the state and U.S. Supreme Courts, Frank Athen Walls was executed for the 1987 double murder, drawing a conclusion to years of appeals and confessions.

In a brief statement before his execution, Walls expressed his remorse, as conveyed by Alex Lanfronconi, a spokesperson for Governor Ron DeSantis.

“Good evening, everyone,” Walls reportedly said. “I appreciate the opportunity to say what’s on my heart. If any of the members of the family are here, I am sorry for all of the things I did, the pain I caused, and all of that you have suffered all these years.”

The execution started after Walls issued the statement, and the priest remained next to Walls, appearing to pray.

After tying them up, Alger managed to break loose and confront the attacker. Walls cut Alger’s throat and shot him in the head as the airman fought back, then moved to Peterson and shot her as she struggled.

The day after the bodies were found, Walls was arrested after his roommate notified police about his odd behavior.

Investigators searched the home and reported finding items from the crime scene. Walls later confessed to the killings.

Following his conviction, DNA evidence connected Walls to the May 1987 rape and murder of Audrey Gygi. He pleaded no contest, sparing him another trial and a potential death sentence.

Walls also admitted responsibility for the killings of Tommie Lou Whiddon in March 1985 and Cynthia Sue Condra in September 1986 as part of a deal with prosecutors.

His attorneys appealed the convictions in state court, claiming he should be disqualified from execution because of his intellectual disability and other medical issues. However, last week the Florida Supreme Court ruled against Walls.

The U.S. Supreme Court also denied his request for a stay of execution on Thursday afternoon.

Walls woke up at about 5:10 a.m. Thursday, and according to corrections department spokesperson Jordan Kirland, he remained compliant.

Officials did not say whether any family members of the victims would attend the execution.

Forty-six men have been executed by court order so far in the U.S. this year, and more than a dozen others are scheduled to be put to death next year.

The Supreme Court reinstated the death penalty in 1976, and since then the most executions Florida had carried out in a single year was eight, set in 2014.

Florida has executed more individuals this year than any other state, followed by Alabama, South Carolina and Texas, with five each.

Florida’s lethal injections use a sedative, a paralytic and a drug that stops the heart, according to the Department of Corrections.
