A man has been arrested for fatally shooting 45-year-old Yan Zhiwen, a delivery person for the Chinese restaurant Great Wall in New York City. Police charged Glenn Hirsch, 51, with murder and gun possession after identifying him as the man who allegedly gunned down Yan in Queens on April 30 while Yan was delivering food on his scooter. Hirsch has a history of increasingly violent encounters with the restaurant’s owner, Kai Yang, after he claimed he wasn’t given enough duck sauce for an order in November, police said. Yang offered him more duck sauce for free and refused his demand for a refund, which escalated into Hirsch calling the police. Since then, Hirsch had allegedly targeted Yang and his employees by waiting outside the restaurant, slashing Yang’s tires and pointing a gun at Yang. Hirsch has at least 10 prior arrests, including one instance of armed robbery, police told the New York Daily News. New York Police Commissioner Keechant Sewell described Yan, who leaves behind a wife and three children, as “a beloved member of his Queens community whose tragic murder in April was heartbreaking” in a tweet Thursday.
