Institution Annual Report
Sending Money, Mail, & Property
Columbia Correctional Institution (CCI) protects the public by detaining adult male felons committed by state courts to the DOC and by readying these men for custody reduction and eventual reintegration into society. Protection of the public is both an immediate and long-range focus, as virtually all inmates will eventually be released. Through a philosophy of strict and constructive treatment, both perspectives are met.
