Officials in southeastern Montana have released the names of the two people who died when the car they were in collided with a school bus on icy roads on the Northern Cheyenne Indian Reservation.

The Rosebud County coroner's office says the crash Thursday morning east of Lame Deer killed 28-year-old Aubree Wallery and her father, 59-year-old Steven Wallery.

Both are from Billings.

The Montana Highway Patrol says Aubree Wallery was driving east on U.S. Highway 212 and going downhill on a slope that curved to the right when her car crossed the center line and collided with the westbound bus.

One person on the bus suffered minor injuries.
