State police say a 43-year-old Owosso woman has died in a snowmobile crash in southwestern Michigan.

Troopers called to a wooded area of Berrien County early Saturday found the woman dead at the scene. Her name has not been released by authorities. Investigators say she was a passenger on the snowmobile and suffered a major head injury when she was thrown from it during the crash. A 31-year-old Owosso man who was driving the snowmobile suffered serious back and pelvis injuries and was listed in serious but stable condition at a Kalamazoo hospital.

Investigators say both victims were not wearing helmets and a preliminary investigation suggests that alcohol may have been a contributing factor in Saturday's crash. (JK)
