John Justin Bunting (born 4 September 1966 in Inala, Queensland) was found to be the leader of the perpetrators. When he was 8 years old, Bunting was beaten and sexually assaulted by a friend's older brother. He is reported to have "enjoyed weaponry, photography and anatomy," and grew to develop a strong hatred of paedophiles and homosexuals. At age 22, Bunting worked at an abattoir and reportedly "bragged about slaughtering the animals, saying that's what he enjoyed the most". Bunting moved to a house in Salisbury North, South Australia in 1991 and befriended his neighbours Mark Haydon and Robert Wagner. Robert Joe Wagner (born 28 November 1971 in Parramatta, New South Wales) was befriended by Bunting in 1991. Bunting encouraged Wagner to assist in the various murders. James "Jamie" Spyridon Vlassakis (born 24 December 1979), along with his mother and half-brother, lived with Bunting and was gradually drawn into helping with the murders. Vlassakis, 23, helped torture and kill his own half-brother, Troy Youde, and his stepbrother, David Johnson. He confessed in 2001 to four murders, including Johnson's, and became a key witness for the Crown. The detail he provided, supported by other evidence, helped convict Bunting and Wagner. Vlassakis was sentenced in 2002 to a minimum of 26 years and is held in isolation in an unidentified South Australia prison. Mark Ray Haydon (born 4 December 1958), an associate of Bunting, was initially the subject of "suppression orders or statutory provisions prohibiting publication" and could not therefore be identified as anything other than an alleged perpetrator. In January 1999, he reportedly rented the abandoned state bank building at Snowtown. A jury deadlocked on the murders of Haydon's wife, Elizabeth Haydon,
