SPANISH FORK, Utah (AP) — A baby survived a car crash in a frigid Utah river after being strapped in a car seat upside-down for about 14 hours before being found by a fisherman.

Police said Sunday the 18-month-old girl's condition was upgraded from critical to stable but critical condition at a Salt Lake City hospital, but her 25-year-old mother, Lynn Groesbeck of Springville, was found dead in the car.

Police Lt. Matt Johnson says a fisherman discovered her car on its top about 12:30 p.m. Saturday in the Spanish Fork River in Spanish Fork near Provo.

He says a nearby resident reported hearing "something" about 10:30 p.m. Friday, but was unable to locate anything out of the ordinary.

Police say the infant was found hanging upside down above the river water that flowed through the car.
