Authorities are investigating a shooting incident Tuesday night that damaged a window of an apartment building in Quincy, left ballistic evidence at Pope John Paul II Park, and led to the recovery of a firearm in Dorchester’s Port Norfolk neighborhood.
A woman sitting in her apartment on Hancock Street reported hearing fireworks or gunshots outside her building, which overlooks the Neponset River, Quincy Police Captain John Dougan said. Arriving officers discovered that a bullet had smashed into the window of the unit, he said.
State troopers went to Pope John Paul II, the state park on the Dorchester side of the Neponset River, where 911 callers reported people under the Neponset Street Bridge were firing a weapon.
Troopers found multiple spent shell casings near the bridge, State Police said, adding they believe the shells are connected to the damage in Quincy.
Separately, Boston police went into the Port Norfolk neighborhood and recovered a firearm, Boston police said.
Law enforcement questioned some people, but the three police agencies said they had not arrested anyone.
