Xin Chris Gu was 31 when he was killed in an execution-style shooting outside a karaoke bar in Flushing, Queens, on the morning of February 12, 2019. Gu had been celebrating the Lunar New Year with more than 100 guests and had just launched his new real estate development company, KG Management, before he was shot as he waited for an Uber around 2:30 a.m.

Investigators say the killing was part of a murder-for-hire plot tied to business rivalry. Authorities identify Qing Ming Allen Yu as the alleged mastermind; Gu had worked for Yu’s Manhattan company, Amaco, before resigning in 2018 to start his own firm, and several clients and employees reportedly followed Gu to his new venture. Antony Abreu is named as the shooter, Zhe Zack Zhang as the getaway driver, and another co-conspirator is identified as You You. Abreu was reportedly rewarded with an expensive Richard Mille wristwatch for his role.

All four men were arrested and charged in connection with the murder-for-hire. Did anyone at the celebration or in the Flushing area that night see something that could help clarify how the plot was carried out?
