Unfortunately, Jean passed away in 2010 and it’s unlikely that police will ever be able to conclusively connect their prime suspect, convicted killer Peter Tobin, due to the deterioration of physical evidence. Jean’s information helped investigators form a psychological profile of the killer and the man’s many Bible references led to the “Bible John” nickname.

The key information in the case came from Helen Puttock’s sister Jean, who had driven in the same taxi as her sister and the suspected killer the night she was murdered. All three victims had been beaten and raped prior to their murders and had all met the killer at the same Glasgow club, the Barrowland Ballroom. Regarded as Scotland’s biggest manhunt, the hunt for Bible John has turned up multiple suspects over the years, but his identity has never been proven in the 45+ years since the murders of Patricia Docker, 25, Jemima McDonald, 32, and Helen Puttock, 29, occurred. Unfortunately, investigators have concluded that it would have been impossible for Fowler to have commited most of the murders given his movements at the time, so it is likely that the other killer or killers remain at large. The DNA of serial killer Bobby Fowler, who passed away in 2006 while in prison, was discovered on the body of Colleen MacMillen, who went missing in 1974. Given that the murders span almost a 50 year period, it is believed that there have been multiple killers along the Highway of Tears, with only one suspect ever being implicated definitively in some way. Perhaps the most infamous of these is the Highway of Tears in British Columbia, a 720 km (450 mi) stretch of Highway 16 between Prince George and Prince Rupert that has seen at least 18 (and possibly as many as 40) predominately aboriginal women murdered between 19. While the United States is generally thought of as the serial killer capital of the world, Canada has had its fair share of heinous murders, including more than a few that remain unsolved. Despite a few promising leads, including most recently the discovery of a Blue AMC Gremlin suspected of having been the killer’s car, the case remains open.

The truly disturbing part of the whole case was that each of the children -Mark Stebbins, 12, Jill Robinson, 12, Kristine Mihelich, 10, and Timothy King, 11 - were discovered fully-clothed and washed, and were held anywhere from 4 to 19 days before being killed. Due to children being the only targets, the investigation set off a wave of mass hysteria in the state of Michigan at the time, with parents understandably obsessed with educating their children on “stranger danger” and instituting many neighborhood watch initiatives. The killer received their nickname because each child was bathed prior to their murder, suggesting the killer had some form of twisted parental instinct. The Oakland County Child Killer, better known as “The Babysitter,” is an unidentified serial killer who murdered at least four children in Oakland County, Michigan between 19.
