U.S. Seeks Extradition for Former 'Survivor' Producer Charged With Killing Wife

New documents from Mexican authorities detail the couple's tumultuous relationship via accounts from family, friends and witnesses.

Federal prosecutors in Los Angeles have formally requested that former Survivor producer Bruce Beresford-Redman be extradited to Mexico to stand trial on an aggravated homicide charge, the Associated Press reported.

Beresford-Redman is charged in Mexico with the killing of his wife, Monica, whose body was found in April in a sewage tank at the Moon Palace Hotel in Cancun.

On Monday, Mexican authorities shipped more than 400 pages of investigative documents, which led to the extradition request. The documents detail the couple's tumultuous relationship, via statements from friends, family and witnesses, and also include forensic reports.

Beresford-Redman, who is also a co-creator of Pimp My Ride, has publicly said he is innocent but has not yet entered a formal plea. His attorneys have attacked Mexico's investigation and its case, saying there was evidence that would exonerate their client.

According to the documents, Monica Beresford-Redman's friends and sisters told Mexican authorities that the couple had been having marital problems long before their trip to Cancun. One friend recounted an early strain on their relationship occurred when Bruce Beresford-Redman racked up more than $5,000 in phone sex charges, a bill his wife sent to his mother to pay.

The L.A. restaurant owner also became suspicious of her husband and his relationship with an assistant, according to the documents. He admitted having an affair but rejected her calls to get a divorce, according to statements from her friends and sisters.

The filings also provide recollections from a resort worker who described seeing the couple in a heated argument before her body was found April 8.

A concierge recounted taking a complaint from a British family that heard commotion in the room the couple shared with their young children. The woman told authorities she asked the producer about the incident, and he admitted arguing with his wife the night investigators think she was killed, but he told her "it won't happen again."

Stephen Jaffe, a spokesman for Bruce Beresford-Redman's defense lawyers, said there was no indication that the documents had been given to the attorneys yet. "Until such time as they have been delivered, they cannot comment on their authenticity," Jaffe said.
