CANCUN, Mexico (AP) — Mexican investigators say they are waiting for the results of forensic tests before deciding whether to arrest a Hollywood television producer in the death of his wife.

Quintana Roo state Attorney General Francisco Alor says investigators are waiting for the results of forensic tests on the body of Monica Beresford-Redman.

He gave no details on the tests at a news conference Monday.

Former "Survivor" producer and "Pimp My Ride" creator Bruce Beresford-Redman is barred from leaving Mexico and his passport has been confiscated.

His wife was found dead in a sewer at the Moon Palace resort last week. Investigators say witnesses saw the couple arguing the night before the producer reported her missing.
