Same gun used in killing of Colorado prisons chief and Texas shootout, authorities say

Colorado authorities said Monday that the same gun a white supremacist fired in a gunbattle with Texas police last week was also used in the shooting death of Colorado's prisons director.

Texas police killed Evan Spencer Ebel, 28, after a high-speed chase Thursday through Decatur, Texas.

He is also considered a suspect in the death of Tom Clements, executive director of the Colorado Department of Corrections, who was shot at his home near Denver last Tuesday, Colorado authorities say. He is believed to have shot and killed a pizza delivery man and used his uniform to get to Clements' front door without raising suspicion.

Monday's ballistics report "goes well beyond" Texas officials' determination last week that shell casings at the scene of the shootout were from the same type of ammunition, the Colorado Springs Metro Crime lab said in a statement.

Ebel had been paroled in January from a Colorado prison, and there is strong evidence to connect him to a white supremacist prison gang called the 211 Crew, which experts say demands that some of its members commit crimes once they leave prison.
