(Scroll down for video) A prisoner who warned a judge that if he is not executed he will keep on killing more prisoners, was executed, according to a statement by prison officials in Virginia.

The man who strangled his prison cellmate and fulfilled the promise to continue killing if not executed, has been executed in Virginia's electric chair.

Robert Gleason Jr. was pronounced dead by authorities at 9:08 p.m. Wednesday, at the Greensville Correctional Center.

The 42-year-old prisoner, was the first prisoner in the U.S. this year to choose to die in the electric chair. In Virginia and nine other states, inmates may choose electrocution or lethal injection.

Gleason had fought last minute attempts by former lawyers to stop the execution. He said that he deserved to die for what he did.

Gleason was serving a life sentence for a murder when he killed his cellmate. He choked another inmate.
