A man fell from a moving vehicle onto a west metro freeway Monday morning, and the State Patrol is trying to figure out why. Did he jump or just fall? Was he thrown?

Authorities are looking for the vehicle involved in the incident, which occurred about 5:45 a.m. in the westbound lanes of Interstate 394 in the vicinity of Louisiana Avenue between Golden Valley and St. Louis Park.

A patrol spokeswoman said investigators have little information about the vehicle, other than it may have been a Lincoln crossover or similar light-colored vehicle.

It was not clear how many people were in the vehicle, which was moving at freeway speeds when the victim tumbled to the pavement, said Lt. Tiffani Nielson.

The victim, identified as 30-year-old William Watson of Minneapolis, was taken to North Memorial Health Hospital in Robbinsdale with critical injuries.

Traffic was light at the time of the incident, which was caught on MnDOT traffic cameras. Authorities closed two westbound lanes of I-394 for about an hour just as the rush hour began.

Nielson said the patrol has spoken to one witness but is hoping others may have seen the incident or the vehicle. Anybody with information can call the patrol at 651-582-1511.
