The Disappearance of Helen Claire Frost

And who or what was responsible for her disappearance?
There are the suspects in the Highway of Tears cases. Three serial killers have been charged and convicted of some of the crimes. Cody Legebokoff, Peter Arp and Edward Dennis Isaac. Another, Bobby Jack Fowler, has been implicated, but died before charges could be brought. Fowler is perhaps a likely consideration. He was a construction worker who travelled across the whole of the Americas and is known to have spent time in British Colombia. His DNA was found on one of the Highway of Tears victims, Colleen Macmillen. He was strongly suspected of the killings of Gale Weys and Pamila Darlington in the early seventies. The authorities in Canada believe he is connected to at least ten other deaths. His first suspected killing dates back to 1969. He was known for picking up hitchhikers. To his twisted thinking, women who asked for a ride where also asking to be raped or assaulted.
Yet, on the other hand, it is easier to attach unsolved deaths and disappearances to already known killers than to seek out more hidden suspects. Certainly, there are dissenting voices on the Canadian police force regarding the involvement of Fowler in any of the Highway of Tears murders. The sad fact remains that almost nothing more is known about what happened to an unhappy and troubled seventeen-year-old today than when she first went missing in October of 1970.
