Ennis resident Patti Sue Pederson died in a two-vehicle accident early Tuesday afternoon.
Pederson, 56, was heading toward Bozeman on Montana Highway 84 about seven miles east of Norris when she veered across the center line and collided head on with an oncoming vehicle. She was pronounced dead at the scene.
The other people involved in the crash were from Billings and treated at Madison Valley Medical Center and released.
Madison County undersheriff Roger Thompson said the cause of the accident is still unconfirmed, but alcohol doesn’t appear to be involved.
Multiple fire department units from Harrison Fire Department, Madison Valley Rural Fire Department along with Ennis Ambulance and the Harrison Quick Response Unit responded to the scene. The road was completely blocked and closed for several hours as a result of the accident. Montana Highway Patrol is investigating the crash.
