(NEW YORK) -- The man involved in a high speed car chase and shootout in Texas, who police are eyeing for the murder of Colorado's prisons chief and a pizza delivery man earlier in the week, is a paroled Colorado inmate and white supremacist gang member with the word "hopeless" tattooed on his body, sources tell ABC News.
Evan Spencer Ebel, 28, has been tentatively identified as the shooter who opened fired at police in Texas when they pulled him over during a routine traffic stop on Thursday, sources told ABC News. He is believed to have shot one deputy three times and then started a 100 mph car chase across two Texas counties while continuing to shoot at officers.
The chase ended when the driver was hit by an 18-wheel truck. The suspect emerged from the wreck and kept shooting at cops until he was cut down by return fire, according to Wise County Sheriff David Walker.
The suspect was flown to a hospital in Fort Worth, where he is awaiting organ harvesting, though police said he was "legally deceased" after the shootout.
Ebel has been in and out of jail the last 10 years, and was a part of a white supremacist prison gang, sources say.
He had the words "hopeless" and "Evil Evan" tattooed on his body, friends say.
Police are checking fingerprints and examining the weapons found to determine whether Ebel also killed Colorado prison executive Tom Clements on Tuesday.
Clements, 58, was shot and killed at his home. Neighbors told police they saw a black, "box style" car in the neighborhood at the time of the murder.
The driver involved in the Texas shootout on Thursday was driving a black Cadillac with Colorado license plates matching the "box style" description.
Police are also investigating whether Ebel was involved in the murder of a pizza delivery man in Denver on Sunday. Texas authorities said evidence found Friday in the suspect's car -- including a Domino's pizza uniform jacket and a cardboard pizza box -- may link him to the unsolved murder of Nathan Leon, 27, who was killed delivering pizzas near Golden, Colo.
