Charles Newton Powell was killed in Yuma, Arizona, in the early hours of June 25, 1992. Powell, a construction foreman in town for a job, was staying at the Hacienda Motel on Fourth Avenue. A motel witness heard a knock, later saw an unknown person speak with Powell, and then heard what they first thought was a slamming door but was a single gunshot. The witness then saw someone running from the scene.

Yuma police responded and found Powell dead from a gunshot wound; investigators produced a composite sketch of the fleeing person and questioned several people but never developed enough evidence to make an arrest. The case remains unsolved and cold decades later. If anyone was in or near the Hacienda Motel that night or recognizes the composite description, please come forward with information.
