"I know he was having an affair," Carla Burgos told Radar Online. "And she found out."

Bruce Beresford-Redman is at the center of an investigation into the death of his restaurateur wife.

He has been described as a nice guy who was frequently away from his family while working on television series as CBS' long-running "Survivor" and ABC's zany driving game show "Crash Course," according to the Associated Press. He also worked on "Pimp My Ride," for MTV.
