Evan Ebel, the man suspected of killing Colorado prisons chief Tom Clements, probably would still be behind bars were it not for a law approved by legislators and Gov. John Hickenlooper in 2011, reports the Denver Post. The law, which had Clements’ approval, allowed inmates such as Ebel to earn time off their sentences for the months and years they had spent in administrative segregation, commonly known as solitary confinement. That changed the previous rules that provided inmates time off for good behavior, but that time could be earned only outside administrative segregation. Ebel had spent most of his adult life in so-called ad-seg. From the time he entered prison until just days before his release on mandatory parole, Ebel was a menace to himself and others. Newly released documents outline his attacks on guards and fellow inmates, death threats against guards, and a total of 28 disciplinary write-ups. Ebel walked out of prison Jan. 28, about 115 days earlier than he would have under the 2011 law.
