(Kingsbury, IN) - A woman has died from injuries sustained in a snowmobile collision with a motor vehicle in Kingsbury over the weekend.

This morning, the Indiana Department of Natural Resources reported the death of Alysen Walls, 21, of South Bend. She had been in critical condition with a severe head injury since the Saturday night crash.

According to DNR, the woman was a passenger on a snowmobile driven by Spencer Laskowski, 20, of Osceola, Indiana. Conservation Officer Alex Neel said the snowmobile was traveling in a yard when it crashed into the front end of a motor vehicle parked in a driveway in the 300 block of U.S. 6.

Walls was flown by helicopter to Memorial Hospital in South Bend. Laskowski was treated at Northwest Health for minor injuries, DNR said.

There was a driver in the vehicle parked in the driveway with the engine running at the time of the crash. Walls and Laskowski were not wearing a helmet or any other protective gear as recommended when riding on a snowmobile.

Though the driver's blood-alcohol level was not released, alcohol is considered a contributing factor in the crash.
