Bruce Beresford-Redman, a former producer on Survivor and Pimp My Ride, has been detailed by Mexican police.
He's suspected of killing his wife.
Earlier today, the body of Monica Beresford-Redman was discovered in a sewer at the Moon Palace resort in Cancun, where the couple had been on vacation.
According to Bello Rodriguez, the attorney general for the area, a security guard at the hotel witnessed Bruce and Monica arguing Monday night and added that Beresford-Redman tried to hit his wife.
Beresford-Redman, who reported Monica missing on Tuesday, has been detained as a person of interest in the case. Officials conducting toxicology tests to see if he had consumed drugs in the past week report that he had scratches on his neck.
No cause of death has been determined.
