A toddler, 2, died early Tuesday morning, after being hit by a car -- on a busy West Valley City street -- while being pushed in a stroller, by his mother.

Police say the mother was walking with her daughter, 9, and her young son.  The accident occurred on 5600 West, at about 4000 South.

Authorities say the three were crossing the busy road after dark, and outside a crosswalk.

Police are now searching for the driver of a 4-door sports car, with a fin (spoiler) on the back.  Witnesses weren't sure whether it was gray, silver or white.
