"During a check for a plug in a line, they discovered a human torso. The head was actually still attached to the body. It was very much damaged." (Via KCAL)

Police say they believe the discovery is related to remains found Saturday in another water treatment plant in Carson. Employees there reportedly found two legs, a foot, and a pelvis. (Via WBNS)

The two sets of remains most likely flowed into the plants through the Los Angeles County Sanitation District’s sewer system.

Police suspect the body entered the system intact through a manhole before the treatment process pulled it apart. (Via KNBC)

Crews are reportedly in the process of draining the sewage system's tank to find the body's other missing parts, including the left arm. (Via KCBS)

A medical examiner is expected to confirm if the remains belonged to the same body and determine the cause of death.
