Florida executed a 45-year-old man Thursday who confessed to the rape and murder of a child nearly twenty years ago. 

Eddie Wayne Davis was put to death by lethal injection at 6:43 p.m. by the state’s Department of Corrections in Starke, Florida. The U.S. Supreme Court denied a last minute appeal Thursday, just three days after the Florida Supreme Court also rejected his appeal, according to the News Service of Florida.

The New York Daily News reports the Florida court rejected Davis’ claim Monday that he suffered from a metabolic disorder that might cause him to have a painful reaction to one of the drugs administered during the execution. 

Davis is the third prisoner put to death in Florida after the botched execution of Clayton Lockett in Oklahoma earlier this year. Lockett eventually died of a heart attack in the execution chamber after one of his veins collapsed while the lethal drugs were being administered, according to The Guardian.

Witnesses of Davis’ execution said everything went as planned. 

"Initially you could see him fall asleep, he would yawn, the mouth would open and then close, then you would see deep breaths getting shorter and shorter and shorter, and finally stopping," said John Koch, a Florida reporter who has covered 67 executions, according to The Associated Press

Davis was convicted in 1995 for first-degree murder, kidnapping and sexual battery in the death of 11-year-old Kimberly Waters. 

Davis confessed to breaking into an ex-girlfriend's apartment in 1994. There he found the young girl sleeping. Prosecutors claimed that he woke up the girl and raped her. 

Following the rape, he took her to a nearby Moose Lodge where he suffocated her with a piece of plastic and then threw her body in a dumpster.

Lt. Terry Storie was just a young officer when he found Waters’ body in the dumpster in Lakeland, Florida, twenty years ago. He said the scene was so shocking that he nearly quit the police force. Storie said he remained in contact with the girl's family through the years and was on hand to see Davis executed. 

“I stayed to see this to an end," he said, adding that he planned to retire soon. 

Members of the victim’s family were also present at the execution.

"It's finally over. Twenty years, four months and six days. We finally have justice," Tom Brimer, Waters' uncle, said.
