closed off with a bulldog clip. He seated his victims in the kitchen, released the clip on the tube, and let gas leak into the room. The Brabin Report pointed out that Christie's explanation of his gassing technique was not satisfactory because he would have been overpowered by the gas as well. It was established that all three victims had been exposed to carbon monoxide. The gas made his victims drowsy, after which Christie strangled them with a length of rope. As with Eady, Christie repeatedly raped his last three victims while they were unconscious and continued to do so as they died. When this aspect of his crimes was publicly revealed, Christie quickly gained a reputation for being a necrophiliac. One commentator has cautioned against categorising Christie as such; according to the accounts he gave to the police, he did not engage sexually with any of his victims exclusively after death. After Christie had murdered each of his final victims by ligature strangulation, he placed a vest or other cloth-like material between their legs before wrapping their semi-naked bodies in blankets (in a similar manner to the way in which Beryl's body had been wrapped), before stowing their bodies in a small alcove behind the back kitchen wall. He later covered the entrance to this alcove with wallpaper. Arrest Christie moved out of 10 Rillington Place on 20 March 1953, after fraudulently sub-letting his flat to a couple from whom he took £7 13s 0d (£7.65 or about £ as of ). The landlord visited that same evening and, finding the couple there instead of Christie, demanded that they leave first thing in the morning. The landlord allowed the tenant of the top-floor flat, Beresford Brown, to use Christie's kitchen. On 24 March, Brown discovered the kitchen alcove when he attempted to insert brackets into the wall to hold a wireless set. Peeling back the wallpaper, Brown saw the bodies of Maloney, Nelson and MacLennan. After getting confirmation from another tenant in Rillington Place that they were dead bodies, Brown informed the police and a citywide search for Christie began. After leaving Rillington Place, Christie had gone to a Rowton House in King's Cross and booked a room for seven nights under his real name and address. He stayed for only four nights, leaving on 24 March when news broke of the discovery at his flat. Christie wandered around
