Former Survivor producer Bruce Beresford-Redman has been convicted of murder in the 2010 death of his wife.

Beresford-Redman, 43, was sentenced to 12 years in prison on Thursday for killing his wife Monica, who disappeared in Cancén after a shopping trip nearly five years ago. Her body eventually was found in the sewer of the Moon Palace resort, where the family was staying.

Suspicion immediately fell on the producer. Mexico authorities said Beresford-Redman hit his wife in the head with a metal tube, bat or stick and then choked her to death before dumping her body in a hotel sewer.

But Beresford-Redman maintains his innocence. “Everyone seems to have decided that I killed my wife,” he told 48 Hours Mystery in 2012. “I didn’t kill my wife – I really didn’t.”

However, Monica’s sisters told the show they believe their brother-in-law killed their sibling. The pair had reportedly been having marital problems prior to her death, and Monica was upset that Beresford-Redman was having an affair.

“I told her, ‘Monica, don’t worry. You know, come back here, just move on with your life,’ ” Monica’s sister Jeanne Burgos told 48 Hours Mystery. “You’re just going to build up your life again and you’re going to be happy again.”

Beresford-Redman’s lawyers plan to appeal the conviction, CBS News reports.
