George Gibson was 47 when he was murdered in his West Chester, Ohio, home on June 22, 2000. He was a veterinarian pathologist. Investigators found he had been shot multiple times—seven times in the head, once in the neck, and once in the chest—after a mysterious phone call prompted him to leave work early. His two Bernese Mountain dogs were also found shot.

Detectives say the killer likely entered through a basement window and lay in wait before the attack; the extreme number of wounds has been described as overkill, suggesting personal motive or deep-seated anger. There were no signs of robbery or obvious high-risk factors. Investigators examined Gibson’s personal and work connections and later learned he had used a dating phone service, which prompted additional lines of inquiry. Leads over the years have included witness accounts, a suspect sketch, and DNA analysis, but the case remains unsolved.

Anyone with information about Gibson, that night, or contacts from his dating service is asked to contact the West Chester Police Department or Ohio Bureau of Criminal Investigation.
