A woman was found dead Thursday at the bank of the Los Angeles River in Long Beach, and authorities were working to determine if foul play was involved in her death.
Police received a call about 1:30 a.m. about a person lying on the rocks of the river, just south of the Ocean Boulevard bridge, said Long Beach police Lt. John Kanaley.
Responding officers found the woman deceased along the river's bank, Kanaley said.
