Yavapai Silent Witness is reminding us about a Cold Case involving a double homicide that happened 18-years ago. In addition, a $10,000-reward is being offered for information that leads to an arrest and conviction. On Friday, October 17-th, 2003, Brandon Rumbaugh and his girlfriend Lisa Gurrieri left Scottsdale for an overnight camping trip north of Phoenix. The couple borrowed a 2000 white Ford F-150 pickup and was to return the following day. When they did not return, a search began. The vehicle and their bodies were found off I-17 on Bumble Bee Road. Both had been shot to death. A borrowed video camera was missing from the scene with its case left behind. A broken disposable camera was also found nearby and had several photos of the victims. Detectives would like information on one picture, a light fixture on the inside of a building.
