A decomposed body was found Monday in the Castaic area near Interstate 5, and investigators are trying to determine whether it is that of a Newhall woman who has been missing for two weeks, authorities said.
The body, believed to be that of a white woman about 18 years old, was found shortly after 1 p.m. behind a strip mall being built near the junction of the 5 and 126 freeways, according to the Los Angeles County Sheriff's Department.
