The two people who died in a crash with a Busby school bus on Thursday have been identified as a father and daughter from Billings.
It happened on Highway 212 between Ashland and Lame Deer.
Aubree Wallery, 28 years old, was driving a 2015 Mitsubishi Lancer, and her father Steven Wallery was in the passenger seat.
Montana Highway Patrol says the Mitsubishi was heading east and negotiating a right curve when the small car crossed over the center line and crashed head-on into the Busby school bus heading west.
Both died at the scene; Aubree was wearing her seat belt, Steven was not, according to the MHP.
A 27-year-old male school bus monitor was inured and taken to the Lame Deer hospital. The MHP says the 43-year-old school bus driver and student on the bus were not injured, but were both to the Lame Deer hospital to be checked out.
Speed was considered a possible factor, according to the MHP. Alcohol and drugs were not factors, troopers said. Road conditions were extremely slick at the time.
Agencies that responded were Ashland QRU, Ashland Fire, BIA, Lame Deer Ambulance, Lame Deer DES, Montana Department of Transportation, Montana Highway Patrol, Montana Motor Carrier Service, Rosebud County Sheriff's Office and Rosebud County Coroner.
