Marcus Wellons: First US execution since botched procedure in Oklahoma

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.

Shortly afterwards John Winfield was executed in Missouri for two killings.

The men were among three set to die within 24 hours, after nine executions were stayed since one in Oklahoma went wrong seven weeks ago.

A last-minute appeal by Marcus Wellons over the source of the drugs used to kill him failed at the Supreme Court.

He was pronounced dead at 23:56, more than an hour after the execution began, a Georgia corrections spokesperson said. No obvious complications were reported.

John Winfield was executed by lethal injection just after midnight on Wednesday for killing two women in 1996.

Officials in Oklahoma halted the execution of Clayton Lockett in April after he began making noises, and he died of a heart attack less than an hour later.

Like Oklahoma, Georgia and Missouri refuse to say where they are obtaining drugs for lethal injections, or if they are tested.

Lawyers for Marcus Wellons, as well as others on death row, have challenged such secrecy in court.

John Ruthell Henry is scheduled to be executed at 18:00 local time on Wednesday in Florida.
