BOZEMAN, Mont. (AP) The Montana Highway Patrol says a collision between a pickup truck and a semitrailer near Three Forks killed a 19-year-old UM student from Helena and injured two others.

Sgt. Pat McCarthy says the pickup slid across the interstate median Sunday afternoon and collided with a semi headed in the opposite direction. Killed in the crash was Joseph Michael McKeon, who authorities say was driving the pickup back to Missoula after attending the Bobcat-Grizzly Football game in Bozeman.

An 18-year-old woman who was riding in the truck was taken to a hospital, as was the 57-year-old man who was driving the semi.

Their names have not been released.

Authorities say speed and winter road conditions played a role in the crash, and alcohol was not a factor.
