A 10-year-old boy was killed after a semitrailer hit a disabled pickup on U.S. Highway 287 Thursday night outside of Cameron.

The Montana Highway Patrol said the pickup had hit two elk and was parked partially in the northbound lane with no lights. A semi heading north hit the truck and caused it to go off the side of the road.

The boy, who’d been a passenger in the truck, was pronounced dead at the scene.

Trooper Hayden Mannetter said the boy was outside of the pickup when it was hit. He said the incident is still under investigation.

A 44-year-old man from Harrison and another 12-year-old boy inside the pickup were uninjured. A 54-year-old man from Spring City, Utah, driving the semi was also uninjured.

Madison County Sheriff Phil Fortner said the corner’s office was not going to release the name of the boy.

MHP said it was the fourth fatality on state roads so far this year.
