Steven Allen Steve Myllo, a 38-year-old white man, was found murdered in Castle Rock, Colorado, on September 10, 1986. Investigators linked his killing to another homicide in Arizona that occurred a few days earlier when they learned the same person was responsible for both deaths. Myllo’s vehicle had been stolen, and that theft became an important link tying the crimes together.

Authorities ultimately identified and arrested a single suspect and pursued legal action in connection with the two murders. The case resulted in a conviction and a life sentence for the perpetrator, closing a violent sequence that had terrorized two communities.

If anyone knew Steven, his routines, or saw his vehicle around that time, please share what you remember.
