A Georgia man convicted of killing his former girlfriend three decades ago is scheduled to be put to death Wednesday in what would be the state’s first execution in more than four years.

Willie James Pye, 59, was convicted of murder and other crimes in the November 1993 killing of Alicia Lynn Yarbrough. The planned lethal injection using the sedative pentobarbital is set to happen at 7 p.m. at the state prison in Jackson.

In their request for clemency, Pye’s lawyers called the 1996 trial “a shocking relic of the past” and said the local public defender system had severe shortcomings in the 1990s.
