Detectives launched an investigation Friday afternoon in Malibu, where the body of a woman was found in a lagoon along Pacific Coast Highway, authorities said.
The body was found just before 1 p.m. along the 23000 block of Pacific Coast Highway, according to Deputy Marvin Crowder of the Los Angeles County Sheriff's Department Information Bureau.
Deputies responding to a report of a possible dead body pulled the woman from the water, Deputy Juanita Navarro-Suarez said in a written statement. She was pronounced dead at the scene.
The body, described as that of a woman in her 30s, was found nude, lying in water about 2 feet deep.
But the circumstances surrounding the death remained a mystery Friday night.
"At this time, cause of death remains undetermined, pending the examination by the LA County Department of Medical Examiner-Coroner," Navarro-Suarez said.
Detectives said it appeared the body had been in the water for less than 30 hours. There were no obvious signs of trauma.
Investigators had not connected the death to any missing persons cases, sheriff's officials said.
