In March 2023, 67-year-old Sueng Chul Choi was working a late-night shift at an Upper East Side deli when a man wearing a hooded hazmat suit entered the store. The assailant ordered a customer to the ground, went behind the counter and began to pistol-whip Choi. During the assault a gun discharged and Choi was struck in the head; he was pronounced dead after emergency responders arrived.

Choi had emigrated from Seoul in 1978. Friends and family said he had been somewhat estranged from relatives, having divorced and with his children living far away. Police later arrested a 42-year-old man in connection with this incident and linked him to other gunpoint robberies across boroughs.

What details about Choi’s final shift, the suspect’s movements before and after the deli, or witnesses at the scene might help clarify exactly what happened that night?
