McALESTER, Okla. (AP) - A career criminal who was convicted of raping and killing a young mother from Mississippi more than 20 years ago was put to death in today (Tuesday) in McAlester, Oklahoma.
Frank Duane Welch was pronounced dead at 6:21 p.m. after receiving a lethal mixture of drugs at the Oklahoma State Penitentiary.
Welch was executed for the death of Jo Talley Cooper, whose murder went unsolved for nearly a decade.
Welch was serving time in prison for a kidnapping charge in 1997 when he was linked by DNA to the killings of Cooper and Grady County resident Debra Stevens.
Cooper, a Mississippi native who earned a master's degree in communication at the University of Oklahoma, was three months pregnant at the time of her death.
