Ebel, 28, who led Texas authorities on a 100-mph car chase that ended in a shootout Thursday, March 21, 2013, may be linked to the slaying of Colorado's state prison chief. / AP Photo/Colorado Department of Corrections KAUFMAN, Texas Authorities are investigating whether the killing of a Texas county prosecutor earlier this year is linked to the slaying of Colorado's prison director. Kaufman police chief Chris Aulbaugh said Friday the FBI is checking to see if the January shooting death of Kaufman County Assistant District Attorney Mark Hasse is connected to Tuesday's killing of prison chief Tom Clements. Hasse was killed about 100 miles away from where former Colorado inmate and white supremacist Evan Spencer Ebel died Thursday after a shootout with deputies. Investigators are trying to determine if Ebel is linked to Clements' death. Meanwhile,shell casings from the shootout are the same make and caliber as those found at the home of Clements after he was killed. The information comes from an application to search the wrecked car of Ebel. Authorities are trying to determine whether the black Cadillac Ebel drove was the same seen outside the home of Clements.
