Authorities say a woman's upper body has been found at a Los Angeles County sewage treatment plant and it's believed her lower half turned up two days ago at another plant miles away.

Investigators are treating her death as a homicide.

Sheriff's Lt. Mike Rosson says workers checking a clogged line found the woman's head and upper torso on Monday at the plant in unincorporated Bassett east of Los Angeles.

A woman's legs and pelvis were discovered in Carson on Saturday.

The plants are connected by large sewer lines. Rosson says the woman's may have dropped through a manhole and been mangled by a treatment system pump before wastewater was sent to the processing plants.

Authorities will try to determine her identity and what killed her.

Correction: Remains were found two days after first discovery, not three.
