John Moore, a 76-year-old Danville businessman and community leader, was fatally shot outside the office building he owned on Fostoria Way on February 24, 2019. He was remembered for his role in developing the Crow Canyon Medical Center and for his involvement with local organizations; family and the community described him as energetic and devoted to service.

Investigators say Moore was shot multiple times by 51-year-old Mark Allan Sypien, who had a documented history of harassment, stalking, domestic violence and threats against Moore and his family after a bitter breakup with one of Moore’s daughters. Moore had obtained a restraining order against Sypien in 2014. Sypien reportedly fled the scene after the shooting; police issued an arrest warrant and described him as armed and dangerous.

Anyone who knew John or has information about Sypien’s whereabouts is asked to come forward.
