WEST HAVEN — A woman was hit by a car and killed Friday as she was attempting to round up two loose horses.

Lori P. Peterson, 53, had followed the horses across 1800 South, at 2100 West, when she was hit by a passing car at about 5:30 p.m., according to Weber County Sheriff's Lt. Lane Findlay. Others were helping Peterson to catch the horses that had escaped from a nearby pasture.

First responders attempted CPR on Peterson, who was unconscious and appeared to have suffered a massive head injury from the collision, Findlay said. Peterson was later pronounced dead at a local hospital.

Findlay said the 55-year-old male driver of the vehicle that hit Peterson was also evaluated at the hospital for possible shock and anxiety.

The incident remained under investigation, although police don't expect filing any criminal charges against the driver. The horses were eventually rounded up by a neighbor and were not harmed.
