A 7-month-old baby in a stroller was killed by a stray bullet when a man on a moped shot at a group of people on a Brooklyn sidewalk. Police Commissioner Jessica Tisch says the shooting unfolded around 1:20 p.m. Wednesday. She says two men sped down a street on a moped and one fired at least two shots at a street corner where several adults and children were standing. Mayor Zohran Mamdani said at a news conference that “There are no words that can mend the heartbreak this family is feeling.” One suspect was in custody. Police said the other was still being sought Wednesday afternoon.
