Police have identified the man fatally shot in Brownsville on Christmas Eve as 46-year-old Marcin Iwanowicz, and for the first time, his family is sharing their story.

News 12 spoke with Iwanowicz’s father on Thursday, a day after the shooting. He said his son left their apartment around 6 a.m. on Christmas Eve, telling him he would be back by 10 a.m.

When hours passed and his son didn’t return, the father said he began calling him repeatedly — but never got an answer.

It wasn’t until around 9 p.m. that police came to their home and told the family that Iwanowicz had been killed.

“I didn’t sleep all night. I just cried half of the night. I didn’t eat nothing,” said his father, Stanislaw Iwanowicz. “I’m old, you know… if you’re young you take everything differently. What am I supposed to do… to die?”

Police say the shooting happened just before 10 a.m. near the corner of Powell Street and Belmont Avenue, outside a clinic where Iwanowicz was receiving care.

Officers responding to a 911 call found him lying on the sidewalk with a gunshot wound to the chest. He was taken to One Brooklyn Health–Brookdale University Hospital Medical Center, where he was pronounced dead.

Investigators spent hours at the scene collecting evidence, including shell casings. A bullet hole was also visible in the wall of the building near where the shooting happened.

Police say no arrests have been made and the investigation remains ongoing.

Iwanowicz’s father said their family came to the United States from Poland, and the loss of his son has left him devastated.

Anyone with information about the shooting is urged to contact Crime Stoppers at 1-800-577-TIPS.
