Officials with the Colorado Department of Corrections said the death of Benjamin Davis is being investigated as a suicide. They didn’t reveal which prison the death happened in or whether it happened in a cell or somewhere else in the facility.

Evan Ebel, a parolee member of the gang, allegedly shot and killed Clements at his house in 2013. Ebel was out on parole after a clerical mistake. He cut off his ankle monitor before he is believed to have gone to Clements’ home in Monument.

Clements was one of two Coloradans police say Ebel killed — Denver-area resident Nathan Leon was the other — before he was killed by police in a shootout in Texas.

At the time, investigators believed Ebel had been in contact with two other members of the gang — Thomas Guolee and James Lohr. Reports then swirled about a possible hit list on the state’s DOC staff crafted by the 211 Crew.
