KUSA - Evan Spencer Ebel, 28, led authorities on a harrowing, 100-mph car chase near Bowie, Texas Thursday that ended after he crashed into a semi and then opened fire before being shot down by his pursuers, authorities said.
Colorado authorities are heading to Texas to investigate the possibility that Ebel may have murdered Colorado prison chief Tom Clemments Tuesday and Domino's pizza driver Nathan Leon on Sunday.
Ebel has a lengthy criminal record, according to the Colorado Department of Corrections.
His record includes convictions for robbery, felony menacing, and assault on a correctional officer.
