Henry "Hank" Skinner came within 45 minutes of lethal injection in March 2010 before the U.S. Supreme Court stepped in -- and ultimately handed him a legal reprieve.
But as another execution date looms, pressure is mounting on Texas officials to grant Skinner's long-standing request to have crime-scene DNA tested before it's too late.
"Executing Mr. Skinner without testing all the relevant evidence would suggest official indifference to the possibility of error in this case and needlessly undermine public confidence in Texas's criminal justice system," said a letter from former Texas Gov. Mark White and 16 other current and former Texas lawmakers, prosecutors and judges, dated October 27 and sent to Gov. Rick Perry, Attorney General Greg Abbott and Gray County District Attorney Lynn Switzer.
Skinner, 49, was convicted of the New Year's Eve 1993 killings of his 41-year-old live-in girlfriend, Twila Busby, and her two adult sons in the Texas Panhandle town of Pampa. He is set to die Wednesday.
He has strongly denied any involvement in the crime and claims that the DNA analysis of untested evidence will prove his innocence and help determine the real killer.
