Of all the murder victims and unexplained deaths on UM, some of them could have had run-ins with serial killers where they met their fate. Who do you think might have been victims of serial killers? I've listed a couple:

Tara Calico-I still acknowledge the theory given by the Sheriff in Belen, New Mexico, but there are numerous other possibilities. Tara could have been one of the many victims of David Parker Ray, who lived only a couple hours away from her home.

Phillip Fraser-The composite sketches of the hitchhiker look very much like Michael Wayne McGray. He also seemed to fit the demeanor type, as indicated by his seemingly calm attitude after Phillip's death (he most likely killed before). The hitchhiker seemed to be a drifter (and not homeless per se) and able to take care of himself plus seemed to travel a lot, which could explain how the RCMP arrived at a conclusion that the hitchhiker is familiar with the Toronto and Seattle areas.

Although unconfirmed, the Blind River Rest Stop murders have been attributed to Ronald Glenn West.
