DECATUR, Texas

Investigators from three Colorado police agencies rushed to Texas to determine if a man identified as a parolee, who was critically wounded by Texas police after a harrowing 100-mph car chase, is linked to the slaying of Colorado’s state prisons chief.

The black Cadillac the suspect drove, with Colorado license plates, matched the description of a car spotted outside Tom Clements’ home in Monument, Colo., just before he was fatally shot while answering his front door Tuesday evening.

Evan Spencer Ebel, 28, was gravely wounded in the clash with police Thursday. Authorities said he was not expected to survive and was hooked up to equipment for organ harvesting.

Colorado investigators immediately headed to Texas to determine whether Ebel was linked to Clements’ slaying and the killing Sunday of Nathan Leon, a Denver pizza delivery man. Police in Colorado would only say the connection to the Leon case is strong but would not elaborate or say if they believe Ebel killed Clements and Leon.

The Denver Post first reported Ebel’s name, and that he was in a white supremacist prison gang called the 211s. A federal law enforcement official confirmed his identity and gang affiliation to The Associated Press. The official was not authorized to speak publicly about the case and spoke to the AP on condition of anonymity.
