Colorado prison chief Rick Raemisch has ordered a review of the circumstances leading to the murders of six inmates at Sterling Correctional Facility over the past four years, officials said Wednesday. Cody Gray, who was serving a life prison sentence for a sex offense, was the latest casualty. He killed Monday morning in a general population cell, said Adrienne Jacobson, spokeswoman for the Colorado Department of Corrections. The review will consider whether mistakes have been made in the classifications of inmates, which dictates whether they are placed in secure prisons. “It’s a high number,” Jacobson said, referring to the six murders. “Mr. Raemisch is not pleased. We’ll look at whether there is an issue at Sterling. Or if it is related to the prison’s size.” [read the full story here]
