Two Larimer County Sheriff's Office deputies died Tuesday evening in a motorcycle crash on U.S. Highway 12 in Idaho [1, 4].

The incident represents a significant loss for the Colorado law enforcement community, as the deputies were killed while off-duty during a trip outside their home state.

According to reports, the collision occurred on Tuesday, June 17, 2026 [3]. The crash involved two deputies and one other man, all of whom died [1, 2].

Investigation into the cause of the accident indicates a head-on collision [2]. Reports said a woman driving a truck attempted to pass another vehicle in a no-passing zone, which resulted in the truck striking the motorcyclists head-on [5].

The Larimer County Sheriff's Office is mourning the loss of the two deputies [1]. The crash took place on a stretch of U.S. Highway 12, a route known for scenic travel but potential hazards during passing maneuvers [4].

Authorities have not yet released the names of the deputies or the other male victim [1, 2]. The driver of the truck involved in the collision has not been identified in available reports [5].

The death of multiple law enforcement officers in a single off-duty accident often triggers multi-agency investigations to determine if criminal negligence occurred. In this case, the reported illegal passing maneuver suggests that the investigation will focus on traffic violations and potential charges for the driver of the truck.
