Spokeswoman JoEllen Smith says 53-year-old Castro was found hanging in his cell around 9:20 p.m. Tuesday at the Correctional Reception Center in Orient. Prison medical staff performed CPR before Castro was transported to a hospital, where he was pronounced dead.
Just last month, Castro was sentenced to life in prison plus 1,000 years on his guilty plea to 937 counts including kidnapping and rape.
