Colorado corrections officials are investigating whether a paroled white-supremacist prison-gang member at the center of the investigation into the execution-style slaying of state prison chief Tom Clements was ordered by the gang to do a “hit,” the Denver Post reports. “What’s not known is whether this was ordered or a crime of opportunity,” said a Department of Corrections employee. The source said a gang leader in prison, called a “shot caller,” could order a member to kill someone. Shortly after Clements’ slaying Tuesday night, Colorado placed all 20 of its prisons on modified lock-down. The suspect was identified as Evan Spencer Ebel, 28, a parolee and as a member of a white-supremacist prison gang known as the 211s. Ebel led Texas authorities on a wild chase and shootout yesterday. He was wounded and was on life support and considered brain-dead at at Ft. Worth hospital.
