Lisa Marie Gurrieri, 19, and her 20-year-old boyfriend Brandon Rumbaugh were found shot to death in the bed of a borrowed white Ford F-150 near Bumble Bee Road north of Phoenix, close to Black Canyon City. The couple had gone camping to celebrate their one-year anniversary on October 17, 2003; their bodies and sleeping bags were discovered the next day after friends found the truck parked in a dirt area. A disposable camera recovered at the scene contained last images of the couple; their video camera is missing and has never been recovered.

The Yavapai County Sheriff’s Office opened a homicide investigation. Early on there were no immediate signs of robbery or struggle. Investigators questioned a man described as jealous who passed a polygraph and later moved out of state, and they considered a possible link to a later similar crime whose suspect died before he could be questioned. No arrests have been announced and the case has gone cold, though evidence has been re-examined with tools such as genetic genealogy and a $10,000 reward remains for information leading to an arrest.

Did anyone who knew Lisa or Brandon, or who was in the Black Canyon City area in October 2003, ever see the couple or that white Ford F-150?
