On February 9, 2015, 49-year-old Ling Tan was found shot multiple times at close range inside his home on Coach Side Lane in Pittsford, New York. Monroe County deputies discovered the body after a domestic disturbance call; standing in the driveway were his 19-year-old son, Charles Tan, and his wife, Qing Tan. Investigators recovered a shotgun from the family garage believed to be the weapon used in the killing, and deputies noted prior calls to the home for domestic disputes.

Charles Tan, then a Cornell University sophomore and a Canadian citizen, was arrested and charged with second-degree murder. His case went to trial in Monroe County Court in September 2015; the defense presented evidence of alleged abuse in the household. The jury hung, and the presiding judge later dismissed the state murder charge for insufficient evidence. Subsequent federal investigation into how the shotgun was obtained led to federal firearms charges.

If anyone knew the Tans or has information about the events leading up to February 9, 2015, please come forward with what was seen or heard.
