Los Angeles teens arrested after mother, stepfather found in shallow graves

Cadavers help police solve crimes? Absolutely. At the University of Tennessee's Forensic Anthropology Center, a.k.a. the Body Farm, cadavers are left to rot under various environmental conditions so scientists can learn just how bodies decompose - and how long it takes them to decompose. Forensic scientists use the data to better locate and recover human remains - and solve crimes.

(CBS/AP) LOS ANGELES - A teenage girl and her boyfriend are being held in connection with the murders of the girl's mother and step-father, whose bodies were found in shallow graves in Norwalk and Long Beach, according to a report.

The 15-year-old girl and a 16-year-old boy were arrested late Wednesday night on suspicion of murder. Their names have not been released because of their age.

Los Angeles County sheriff's Lt. Mary Leef says the girl's mother and stepfather were reported missing from their Compton home Tuesday "under suspicious circumstances." Relatives of the missing couple pointed detectives to the teenagers.

According to local station KTLA the girl had been seen discarding some of her mother's belongings, neighbors said.

The woman's body was found Saturday in a vacant lot in Norwalk. The man's body was found late Wednesday buried in a shallow grave about 15 miles away in Long Beach.

Police have not said anything about a possible motive. The coroner's investigators are working to determine the causes of death.
