In a statement before the execution, Arthur read out the names of his children. "I'm sorry I failed you as a father. I love you more than anything on earth," he said, his voice cracking.
The execution was to have begun at 6 p.m. but was delayed by appeals to the U.S. Supreme Court. If the execution had not begun by midnight, the state would have had to seek another execution date, AL.com reported.
Alabama Attorney General Steve Marshall said he hoped Wicker’s family can begin to recover.
"Thirty-four years after he was first sentenced to death for the murder of a Colbert County man, Thomas Arthur's protracted attempt to escape justice is finally at an end,” Marshall said. “Most importantly, tonight, the family of Troy Wicker can begin the long-delayed process of recovery from a painful loss."
