May 24, 1996. Glendale, Arizona. 19-year old Diana Shawcroft and her 19-year old best friend, Jennifer Lueth, leave their apartment to visit a nearby convenience store, but they never return and are last seen climbing into a pick-up truck with an unidentified man. Three months later, Diana and Jennifer’s bodies are discovered 100 miles away in a remote desert area in Yavapai County and it is determined that they were the victims of a homicide. After their families set up a memorial shrine at the crime scene, photos of the victims are stolen from there, but even though the killer is believed to be responsible, they are never identified.

October 17, 2003. Scottsdale, Arizona. 20-year old Brandon Rumbaugh and his 19-year old girlfriend, Lisa Gurrieri, leave on an overnight camping trip to Yavapai County, but never return home. Two days later, Brandon and Lisa are found shot to death inside their sleeping bags in the bed of their pick-up truck in a remote area located off Bumble Bee Road. The investigation turns up some intriguing leads, including the discovery of a broken disposable camera containing photos of Brandon and Lisa which were taken shortly before they killed, but the “Bumble Bee Road Murders” remain unsolved.

On this week’s episode of “The Trail Went Cold”, we travel to Arizona to explore two unsolved double homicides in which a pair of victims were found murdered in remote desert areas of Yavapai County.
