During the search of the houses of Dutroux, several video tapes were found. They were never looked at. Some of them showed Dutroux constructing the dungeon in which Lejeune and Russo were held. Had police looked at it, they would have found the dungeon containing Lejeune and Russo. The video tapes had been in possession of the police since December 1995. They had been passed on to the prosecutors in the case, but not to the judges. Furthermore, some of the video tapes were returned to Dutroux by police officer René Michaux without ever being looked at.
