DENVER -- Colorado investigators Saturday said for the first time that a former prison inmate who was killed in a gunfight with Texas authorities is a suspect in the death of Colorado's prison system chief.
The evidence gathered in Texas after the death of Evan Spencer Ebel provided a "strong, strong lead" in the fatal shooting of Colorado Department of Corrections director Tom Clements, who was killed at his front door, El Paso County sheriff's spokesman Lt. Jeff Kramer said Saturday.
Kramer also confirmed Ebel had been a member of the 211s, a white supremacist prison gang in Colorado. It was not known if Ebel knew who Clements was and that he was the state's top prison official, Kramer said.
A darkly ironic connection emerged among Ebel, Clements and Colorado Gov. John Hickenlooper when the governor confirmed Friday he was a longtime friend of Ebel's father, attorney Jack Ebel.
Jack Ebel had testified before Colorado lawmakers two years ago that solitary confinement was destroying his son's psyche.
When Hickenlooper interviewed Clements for the top prison job in Colorado, he mentioned the case as an example of why the prison system needed reform, but Hickenlooper said he did not mention Ebel by name.
Hickenlooper's spokesman said Clements did not know specifically who Ebel was.
Clements was shot Tuesday night when he answered the door of his home in a wooded, rural area north of Colorado Springs.
Kramer said investigators were trying to determine whether the 211 gang was involved in Clements' death.
The Colorado Department of Corrections was also investigating Clements' death, but spokeswoman Alison Morgan declined to say whether the 211 gang was a focus of the inquiry.
Denver police say Ebel is also a suspect in the March 17 slaying of pizza delivery man Nathan Leon. Texas authorities found a Domino's pizza delivery box and a jacket or shirt from the pizza chain in the trunk of the car Ebel was driving.
Authorities previously said that car was similar to one seen not far from Clements' home the night he was killed, and bullets Ebel fired at Texas police were the same caliber and brand as the bullet or bullets that killed Clements. But until Saturday they had stopped short of saying Ebel was a suspect.
