COLUMBUS, Ohio — The family of Cleveland kidnapper Ariel Castro planned to claim his body Thursday as investigations sought to determine how a man who was perhaps Ohio’s most notorious prisoner managed to hang himself with a bedsheet while in protective custody.

Castro was a month into his life sentence for holding three women captive in his home for a decade when he committed suicide Tuesday night.

Two reviews ordered Wednesday by Ohio Department of Rehabilitation and Correction Director Gary Mohr were under way, prisons spokesman JoEllen Smith said.

One inquiry will look into the suicide itself, and the other is examining whether Castro received proper medical and mental health care leading up the suicide.
