A man died last night when two semi trucks collided head-on seven miles west of New Raymer in Weld County, according to the Colorado State Patrol.

One of the trucks peeled off of Highway 14 and hit the other vehicle about 9:30 p.m., said Trooper Gilbert Mares. The trucks were headed in opposite directions.

The state patrol is investigating the cause of the crash.

Mares did not know the condition of the man in the other truck.
