Montana: Cal Erickson Mullen and Jason West with fatal DUI Interstate 15 crash; Mullen sentenced to prison for 5 years hard time

West admitted to having four alcoholic drinks earlier in the night. Court documents said his BAC varied from 0.10 at the scene to .08 in a blood test. He also showed signs of impairment in four out of six field sobriety tests.

West is facing three felony charges of criminal endangerment for driving after drinking and inattentively. Prosecutors filed one count per passenger in his vehicle.

After reconstructing the crash, Montana Highway Patrol troopers determined “that a driver paying attention to the road would have had sufficient time and distance to either stop or slow and steer around a hazard in the road,” court documents say.
