(UPDATED 12:15 AM)

After a night of delays, including last-minute appeals to the U.S. Supreme Court, Georgia death row inmate Marcus Wellons was lethally injected Tuesday night.

Georgia Department of Corrections spokesperson Gwen Hogan confirmed Wellons' died at 11:56 p.m., after the execution started at 10: 41.

The 59-year-old death row inmate was the first person to be lethally injected since the botched Oklahoma execution in April.

ORIGINAL STORY

The Supreme Court has refused to grant a last-minute reprieve to a Georgia death row inmate who would be the first person executed in the United States since a botched lethal injection in Oklahoma seven weeks ago.

The justices turned down an appeal from Marcus Wellons, convicted in the 1989 rape and murder of a 15-year-old girl in suburban Atlanta.

Among his appeals was a challenge to the secretive process used by Georgia to obtain lethal injection drugs from unidentified, loosely regulated compounding pharmacies.

Wellons is one of three men scheduled to be executed in a 24-hour period starting Tuesday night.

No one has been executed in the U.S. since April 29.
