Fall Maddie: Verdächtiger beginn Missbrauch an 72-Jähriger - Blick
According to this article, which I read with the help of a translator built into my browser, it was two acquaintances who burgled CB's place and discovered a video camera, and a "video cassette" which is reported to have held "disturbing recordings". This article also notes that CB took off his mask after the attack (of the elderly American woman) as he sat on the end of her bed. The robbers found the blackened goggles worn by the victim in CB's bedroom. According to this article, there was a teenage victim who had been tied to a post and attacked as well.
From this article, it sounds like there was more than one attack recorded on the video cassette. The cassette was left inside a camper van which was scrapped. I suspect it was BP who scrapped it for him (like others here have suggested). Its a shame police didn't find that video. But CB also somehow still had a copy of the video of the attack against the American woman. We know this b/c he is said to have shown it to someone in a bar on the 10th anniversary of her disappearance. I recall reading that CB's friend MT (the guy he was caught stealing diesel with, and who had lived with him for awhile).... had told the burglars he didn't want to see the video of the elderly woman being raped. MT is now convinced that CB is guilty. I wonder if the plea for information was from police to anyone else who the burglars may have shown that video tape to? If they were willing to show MT, they were probably also willing to show other associates as well.
I also wonder who the teenage victim was? I hope she will come forward to talk to LE and report what happened to her if she hasn't already. I can only image the reasons why a victim wouldn't have wanted to come forward then or now.
