MISSOULA, Mont. -

Authorities have released the names of two individuals killed Wednesday in a rollover crash on I-90 outside of Drummond. Granite County authorities tell NBC Montana Katrina May, 23 years old and David Crow, 24 died in the crash. Both are from Colorado.

Crow was a sophomore at Montana State University, according to a school directory. May was a recent MSU graduate, according to a recent MSU press release.

Troopers tell NBC Montana the SUV they were in veered off into the median, then overcorrected and rolled.

Authorities say both occupants of the vehicle were ejected. The victims did not appear to be wearing seatbelts.

One trooper tells NBC Montana that an Army medic and a doctor drove by the scene of the crash, and stopped and tried to help out. Traffic was delayed on the Interstate for at least 30 minutes near the scene of the crash.

Officials are still investigating, and it is not yet clear if alcohol or speed were factors in the crash.
