The body of an unidentified woman was found lying face down in an inch of water in a flood-control channel in Arleta on Saturday morning, Los Angeles police reported.
Officers, receiving a phone tip about 8:30 a.m., went to the channel near the intersection of Arleta Avenue and Devonshire Street and discovered the woman's body, Detective Art Castro said.
Police did not identify the caller.
The woman, apparently Latino and in her 40s, had mouth cuts.
Officers said, however, that they could not determine the cause of her death.
The woman's body was taken to the Los Angeles County coroner's office.
Results of an autopsy should be known Tuesday, Castro said.
