This Was The Moment a Gunman Opened Fire Last Night in Minneapolis, 8 People Shot

Eight people were hospitalized after a shooting late Monday at an unofficial July Fourth celebration at a riverside park in northeast Minneapolis, an official said.

The shooting happened at Boom Island Park at 11:30 p.m., according to the Minneapolis Park Police Department.

Park Police and the Minneapolis Police Department responded to reports of an unidentified person firing shots into the crowd. No formal Independence Day events or fireworks were planned at the park or along the river where visitors gathered to enjoy the holiday on their own, said Dawn Sommers, a spokesperson for the Minneapolis Park and Recreation Board.

Many who attended the gathering left before police arrived, Sommers said.

"A majority of the shooting victims later arrived at local hospitals on their own, where police were notified by the hospitals," she said.

Several of those injured were in critical condition Tuesday. Police haven't released details about the victims. Park police have not made any arrests, Sommers said.
