The commissioner of the Georgia Department of Corrections has scheduled an execution for a man convicted in the 1990 killing of a fellow inmate.

Georgia Attorney General Sam Olens on Tuesday announced that the execution of Warren Lee Hill has been scheduled for 7 p.m. on July 18.

Authorities say Hill attacked Joseph Handspike as he slept and beat him to death with a board. Hill was serving a life sentence at the time for the 1986 slaying of his 18-year-old girlfriend, who died after being shot 11 times.

Authorities say Hill attacked Handspike when he was asleep and unable to defend himself and beat him badly in the upper body and face. He was convicted in July 1991 on charges of malice murder, felony murder and aggravated assault.
