The two people killed in a crash Monday evening were two girls; they were 12 and 6 years old.
Big Horn County Coroner Terry Bullis said the girls were from the Busby and Lame Deer area.
They died after the vehicle they were in, a 2006 GMC Yukon, driven by a 15-year-old male, drifted out of the eastbound lane on U.S. Highway 212. A report by the Montana Highway Patrol states the vehicle rolled when it hit a culvert, ejecting three of the six passengers. The report also says that alcohol may have been a factor in the crash.
The other passengers were a 13-year-old girl, a 5-year-old boy, and a 15-year-old girl.
The MHP report says no one was wearing a seatbelt and everyone was taken to the emergency department in Lame Deer. Their current conditions are unknown.
A 2001 Dodge Stratus driving through the scene struck one of the ejected passengers.
The driver and two passengers of the Stratus, all females in their early 20's, were also taken to the Lame Deer emergency department. Their conditions are also unknown.
Terry Bullis said the names of the girls killed in the crash will likely be available Tuesday afternoon.
