The lawyer for the Ohio kidnapper Ariel Castro, who held three women captive for almost a decade, has said that his client should have been tested to see whether suicide watch was needed.
Craig Weintraub told Cleveland newspaper the Plain Dealer that he did not understand the rationale behind denying Castro the opportunity to be assessed for suicidal tendencies.
Being on suicide watch would have meant that he was checked up on every 15 minutes.
Mr Weintraub added: "He's still a human being, this is still a civilised society. There's still an obligation to prevent our inmates from committing suicide."
The victims of Ariel Castro - Michelle Knight, Gina DeJesus and Amanda Berry - have been made aware of his suicide, but will not be commenting, according to a CNN editor.

Castro had been incarcerated since August 5 at the Correctional Reception Center, a prison processing facility outside Columbus, the state capital, about 150 miles southeast of Cleveland.

He was housed in protective custody which means he was in a cell by himself and rounds are required every 30 minutes at staggered intervals.
A thorough review of this incident is underway.
Prison medical staff tried to revive Ariel Castro after he was found hanging in his prison cell but failed, according to CNN.
Castro was taken to The Ohio State University Wexner Medical Center where he was pronounced dead at 10.52pm local time.
