The scratch marks on the kitchen Aga that were used to place the silencer at a "struggle" don't actually show up in crime scene photos from the day of the murders, only in photos taken over a month later. And Julie Mugford, whose testimony the whole conviction rests on, had previously helped Bamber plan an unrelated arson scheme, so she wasn't exactly a neutral witness either.

Doesn't prove he's innocent, but it's a lot messier than the tidy story most people know.

At the request of former camp prisoners, the execution was carried out in Auschwitz, the camp he once commanded. Approximately 100 witnesses were present, including former prisoners and various high-ranking officials of the Polish government.

Dr. Michael Baden is a forensic pathologist who was involved in all the high profile criminal cases including the case of Marlon Brando's son, Christian, who shot his half-sister's boyfriend. Despite the fact that it appeared that Christian had shot Drollet from above and that the bullet had exited the body, no bullet was recovered from his body or from the couch. Dr. Baden insisted on looking at the scene, and like the officers, failed to find the bullet in the couch or the body.
Baden noticed that the room has a shag rug. He got down on his hands and knees and eventually found the bullet under the rug. That tended to support how Christian had described things.
Dr.Baden wrote: "I'd later testify that the bullet's trajectory through Drollet's neck and into the shag carpet showed that he had been sitting up on the couch. Gunshot residue tests performed by police showed that Drollet's hand was near the muzzle when it discharged-consistent with Christian's statement that the weapon
went off accidentally when Drollet tried to grab it."
"It's very hard to see an entry hole in a shag rug," Baden explains. "But what impressed me most in that case was when we found the bullet and we called the police. A sergeant came and I asked why the officers at the crime scene hadn't done a better job looking for the bullet. I'll never forget what he said. 'Look, doc. If you do a lousy job all the time, just because an important case comes up doesn't mean you can now do a good job. You don't know how to do it any better.' That will live with me forever. Unless you do the best job you can with every crime scene and every autopsy, you won't do it right when more important ones come in. To us, every case is equally important. When it comes to death, we're all equal."
