The Virginia Supreme Court has upheld the death sentence of a man who killed his cellmate and another inmate at the state's most secure prisons and vowed to keep killing unless he was put to death.
The court issued its ruling on Thursday after a mandatory review of Robert Gleason's sentence.
Gleason was serving a life sentence for murder in 2009 when he killed his cellmate, Harvey Watson Jr. After warning prison officials he would kill again if not sentenced to death, Gleason strangled inmate Aaron Cooper in an adjoining outdoor recreation cage at Red Onion State Prison in July 2010.
