Georgia’s pardons board denied Marcus Wellons clemency on Tuesday
The US state of Georgia has carried out the first execution in the US since a botched lethal injection in Oklahoma in April.
Marcus Wellons, who raped and killed a 15-year-old in 1989, died by injection of a single drug late on Tuesday.
A last-minute appeal over the source of the drugs failed at the Supreme Court.
Wellons is the first of three set to die in the next 24 hours, after nine executions were stayed since one in Oklahoma went wrong seven weeks ago.
He was pronounced dead at 23:56 (03:56 GMT), more than an hour after the execution began, a Georgia corrections spokesperson said. No obvious complications were reported.
Officials in Oklahoma halted the April execution of Clayton Lockett after he began making noises, and he died of a heart attack less than an hour later.
Like Oklahoma, Georgia refuses to say where they are obtaining drugs for lethal injections, or if they are tested.
Lawyers for Wellons, as well as others on death row, have challenged such secrecy in court.
John Winfield in Missouri is scheduled to be executed at midnight on Wednesday, followed by the execution of John Ruthell Henry at 18:00 local time on Wednesday in Florida.
Georgia and Missouri both use a single sedative pentobarbital. Florida uses a three-drug combination – midazolam hydrochloride, vecuronium bromide and potassium chloride.
