On the evening of December 7, 2015, 68-year-old Ying Guan Chen was shot after leaving a wedding reception at the Golden Imperial Palace restaurant in Sunset Park, Brooklyn. Surveillance footage shows another guest, 46-year-old Wu Long Chen, follow Ying Guan Chen to the corner of Seventh Avenue and 61st Street. There, Wu Long ambushed him and shot him multiple times in the head, chest, and arm. Ying Guan Chen staggered into a nearby Popeyes, told employees in Mandarin he was going to die, and was taken to Lutheran Medical Center, where he died of his wounds.

Investigators tied the attack to a decades-old family feud originating in a village in China. Prosecutors say Wu Long harbored a grudge over a building dispute that had seriously injured a relative more than 20 years earlier; unable to find the relatives he blamed, he targeted their father despite Ying Guan having no direct role in the original dispute. Wu Long fled to Texas after the shooting and was arrested in Laredo on December 31, 2015; he was charged with second-degree murder and criminal possession of a weapon.

Does anyone have information about Ying Guan Chen’s life in Brooklyn or who might have known about lingering tensions from the old dispute?
