A white supremacist parolee possibly connected to the murders of the head of Colorado's Department of Corrections and a pizza delivery man has died from wounds sustained during a shootout with police in Texas, an official said.

Tarrant County Medical Examiner's spokesman Roger Metcalf said an autopsy has begun on the man, believed to be 28-year-old Evan Spencer Ebel. His identity must still be officially confirmed through fingerprint analysis, Metcalf said.
