Henry "Hank" Watkins Skinner, 48, is a former oil field and construction worker who was scheduled to be executed on March 24, 2010. The U.S. Supreme Court granted a stay the day he was set to die. The high court heard oral arguments in the case on Oct. 13, 2010.

Skinner was sentenced to death in a 1993 triple slaying of his girlfriend and her two sons. Skinner claims his innocence, insisting for 15 years that DNA evidence could exonerate him.

Prosecutors maintained Skinner isn't entitled to testing of evidence that wasn't tested before his 1995 trial. Skinner contends that he was so incapacitated by alcohol and drugs on the night of the killings that he could not have bludgeoned to death Twila Jean Busby, 40, and stabbed her two adult sons, Elwin "Scooter" Caler, 22, and Randy Busby, 20 in the Texas town of Pampa.
