Marcin Iwanowicz, 46, was shot and killed on the morning of December 24, 2025, outside the St. Jude Treatment Center near Powell Street and Belmont Avenue in the Brownsville/Midwood area of Brooklyn. He had ridden his scooter to the clinic around 6:00 a.m. for his regular methadone treatment and was due home by 10:00 a.m. to help his father prepare the family’s holiday meal. Family members say he was their right hand and a helpful neighbor.

Authorities say an assailant approached Iwanowicz just before 10:00 a.m. and demanded money. When Iwanowicz said he had nothing, a physical confrontation followed and the suspect produced a firearm, shooting him in the chest. Emergency crews took him to Brookdale University Hospital Medical Center, where he was pronounced dead. Investigators recovered shell casings and noted a bullet hole in the building wall; police described the shooter as wearing all black with a yellow hooded sweatshirt and were reviewing nearby surveillance footage. No arrest had been announced in the days after the shooting.

The family, who emigrated to the United States years earlier, had already endured the loss of Marcin’s mother nine years earlier. The scooter he rode that morning remained parked outside the clinic the next day. Did anyone in the area see what happened or have surveillance footage from that morning?
