DENVER -

Colorado is trying to stop the use of solitary confinement for inmates with a serious mental illness as more states rethink whether the punishment poses a greater risk to society when inmates are released.

The mental health impacts of the punishment has received more attention in Colorado after the slaying of former state corrections Director Tom Clements last year. The suspect was a former inmate who had been released after serving eight years in prison, much of it in solitary confinement.
    
A House committee on Tuesday approved legislation that would prohibit placing inmates in solitary confinement if they have a serious mental illness.
    
New York, California, and Massachusetts are among states this year considering proposals to limit the overall use of solitary confinement, according to the American Civil Liberties Union.
