The couple had taken their two children on a family vacation to an exclusive resort in Cancun, during which Beresford-Redman reported Monica missing. After she was found dead of apparent strangulation in a sewer on April 8, he was quickly named a "person of interest" in the death and recently returned to the U.S. even though he had been asked to remain in Mexico while the investigation continued. "I am devastated at her loss and I am incensed at the suggestion that I could have had anything to do with her death. I am innocent," Beresford-Redman said in a statement, calling the charges a miscarriage of justice. But Monica's best friend, Mariza Alyrio, has believed the opposite all along. "I think he killed her because she stood up to him," she told In Touch in April.
