TUSCALOOSA, Ala (Reuters)- Alabama on Thursday executed by lethal injection a man who went on a shooting rampage that killed four people after a night of drinking alcohol and taking drugs in 1992.
Jason Oric Williams, 43, was pronounced dead at 6:19 p.m. local time at the Holman Correctional Facility in Atmore, Alabama, said Department of Corrections spokesman Brian Corbett.
Williams was the first inmate put to death in Alabama using pentobarbital, and his execution was the third in Alabama this year. He had been on death row for 18 years. Williams was the 18th person executed in the United States this year, compared with 46 executions in all of 2010.
Authorities said that after a night of ingesting alcohol, LSD, prescription drugs and crack cocaine in February 1992, Williams went to the home of Gerald Paravicini, his wife and stepson.
The family had taken Williams in two weeks earlier after his ex-wife demanded he leave her home.
When Clair Paravicini's son, Jeffery Carr, opened the door, Williams shot him in the face. He then shot Gerald Paravicini in the chest and neck, killing him.
Williams broke Clair Paravicini's jaw with the butt of a 22-caliber automatic rifle and took her purse with her checkbook, credit cards and $530. Clair and her son survived the attack.
Williams, then 23, left and went to a nearby home. When Linda Barber opened the door, Williams shot her in the face and head, killing her instantly.
He then killed her husband, Fred Barber, and the couple's son Bryan, who was asleep in his bedroom. Another son struggled with Williams and escaped after being shot in the hand.
A jury found Williams guilty of capital murder and attempted murder and recommended the death penalty.
Williams did not request a last meal. He ate from the vending machine in the visitation yard and had hot wings and a sandwich before he was put to death.
Williams' last words were: "I hope that the family of the victims will forgive me for what I have done," Corbett said.
The corrections department changed its protocol to use pentobarbital instead of sodium thiopental in its lethal injection cocktail after Hospira Inc., the only U.S. supplier of sodium thiopental, announced earlier this year it would no longer manufacture the drug.
As a result, several states have switched to pentobarbital, a sedative often used to euthanize animals.
