An execution is scheduled to take place in Tennessee Thursday for a blind death row inmate who fatally set his estranged girlfriend afire.

Lee Hall, who is also known as Leroy Hall Jr., is scheduled to be executed for setting fire to Traci Crozier as she sat in her car in Chattanooga. At the time of the killing, he could see.

Hall’s lawyers say he would be just the second blind person to be executed in the U.S. since 1976. He became functionally blind in prison because of improperly treated glaucoma.

Clarence Ray Allen, who was legally blind and was confined to a wheelchair, was executed by lethal injection in 2006 for ordering three killings while serving time in his prison cell.

“If confined to prison for the remainder of his natural life, Mr. Hall bears no practical risk of harm to anyone,” his lawyers wrote in a court filing.

Hall has chosen to die by the electric chair. He had a choice allowed for inmates convicted before January of 1999.

Hall’s lawyers are requesting Governor Bill Lee delay the execution so the courts can consider claims one of the jurors in the case was biased.
