UPDATE, 5:15 PM: Montana Highway Patrol Sgt. Jay Nelson told MTN News after further investigation that the crash is now being considered a single-vehicle fatality. No other cars came into contact with each other in the incident.
An MHP crash report says the driver who died is a 26-year-old Missoula man. He is not being identified at this time pending notification of next-of-kin. He reportedly was wearing his seatbelt.
The crash report said the driver was headed eastbound on I-90 when he went off the left side of the road, turned right, and overcorrected. He overcorrected again, putting the vehicle into a counterclockwise spin into the median. The vehicle rolled across the westbound lanes of I-90 and came to rest just off the westbound shoulder.
Nelson says with the help of several witnesses who took video of the crash, he wants to get the word out that they are trying to find "someone who may have been a factor in what caused this crash" so they can talk with them and "rule them out."
He hopes anyone with information would call (406) 842-7000.
