A St. Joseph woman was injured in a one-vehicle crash Wednesday night in Cass County.

The Sheriff’s office says the woman was one of four people in a vehicle that was involved in a rollover crash on Crystal Springs, west of Indian Lake Road in Pokagon Township, shortly before 8 p.m.

Weather conditions are believed to have been a factor, but not alcohol or drugs.

The injured woman had to be extricated from the vehicle and was transported to Lakeland Hospital in Niles. Her condition is unknown.
