PLYMOUTH, Minn. — A Minnesota woman is hospitalized after she was trapped in her overturned car on an icy pond for 18 hours.

Authorities say 67-year-old Nancy Breberg, of Centerville, was looking for a hotel in Plymouth when she veered off the road, crashed through a fence, landed on the pond and became trapped in her vehicle.

An officer at the scene told KMSP-TV the ice was breaking around the vehicle when she was found by a bicyclist Saturday, 18 hours after the crash. She was taken Hennepin County Medical Center. Hospital spokeswoman Christine Hill says Breberg remains in critical condition Monday.

Officials say the vehicle wasn’t visible to passing motorists.
