PERHAM —The Otter Tail County Sheriff's Office has released the identify of the 25-year-old man who died after his pickup crashed into an oncoming BNSF train Thursday morning west of Perham, Minn.

Derick Brehm of Vergas was driving a 2014 Chevy Silverado pickup when he struck the eastbound train at approximately 10:50 a.m. The crossing is controlled by a stop sign. Authorities say it is unclear as to why Brehm didn't hear the train.

The crash happened at the intersection of County Highway 80 (Main Street) near R D Offutt Co, according to Rich Luth, a hobbyist who operates the Otter Tail Channel and monitors railroad traffic through Perham.

The truck appeared to be pushed east along the track, to the intersection of county highways 80 and 51 near Kenny's Candy Co., according to eyewitnesses. That's over a half mile.
