Castro was pronounced dead at Ohio State University Medical Center after he was found hanging in his prison cell Tuesday night.
He had been housed at the State Correctional Reception Center in Orient, Ohio, south of Columbus, where he was in protective custody and checked every 30 minutes.
Jaye Schlachet, Castro's attorney, released a statement Wednesday morning:
"We requested the opportunity for a forensic psychologist to evaluate Ariel Castro when he was in county jail and the state's prison reception center. Local and state authorities denied our requests. There is an institutional failure beyond Ariel Castro and the citizens of Ohio are entitled to something better. It's just sad."
