Summary of Offense:
Allen pleaded guilty in the 1986 shooting death of his ex-girlfriend Gail Titsworth in Oklahoma County. He was convicted in 1987. Titsworth had broken off the relationship with Allen three days before the killing and had sought a protective order. She was picking up her two sons at a child-care center when Allen shot her four times. He then struggled with a police officer and was shot in the head. Allen spent months in mental hospitals after his arrest to be treated for depression and his head injury. He was deemed competent at a 1987 hearing but won a new competency hearing in 1997 after the Supreme Court ruled that Oklahoma's competency standards were too high. In the subsequent hearing, Allen was again ruled competent.
