New documents have been released which show that Brittany Kilgore was killed because she refused to participate in S&M activities with the man and two women accused of killing her. Louis Perez got Brittany to go to dinner with him in exchange for helping him do some moving. He bragged to friends he was going to get Brittany to participate in bondage. She refused and it ultimately cost her life. Previously Lopez and his two female companions had kidnapped someone and held her hostage until she agreed to play. I guess they thought this time would work too. It didn't.
