Inmate Loses Challenge to Mississippi's Execution Method

By  | 

Jackson, Miss.
The U.S. Supreme Court has declined to hear a death row inmate's challenge to Mississippi's method of execution by injection.

The court issued its order without comment Monday.

The 5th U.S. Circuit Court of Appeals last November upheld a Mississippi federal judge's dismissal of a lawsuit filed by Roger E. Thorson against Corrections Commissioner Christopher Epps.

A three-judge panel of the 5th Circuit said most of Thorson's claims about the protocol were speculation.

Thorson was sentenced to death for killing a former girlfriend on the Mississippi Gulf Coast in 1987.

Thorson's case marked the second time the 5th Circuit had considered a challenge to Mississippi's lethal injection protocol.

In 2008, a challenge was brought by Leo Dale Bishop and was rejected. Bishop was executed for his role in a 2000 slaying.
