A woman's dismembered body has been found on a San Fernando Valley freeway.

The body, originally thought to be a dead dog's, was reported shortly before 9:30 p.m. Wednesday on the southbound Interstate 5 in Sun Valley.

Lt. Robert Davis says it appears that the woman was struck by several cars and the impact dismembered her.

Davis says it's unclear what the woman was doing on the freeway. He says investigators at first thought she had jumped from an overpass but that has now been ruled out.

Coroner's officials withheld the woman's name until her family is notified.
