The victim, in his 20s, was taken by emergency medical personnel to North Memorial Health Hospital, where he died, police said. Officials have yet to release his identity.

As with Friday night’s killing, no arrests have been announced, and police have not addressed a possible motive.

O’Hara said the majority of road closures are around the Mississippi River’s Boom Island, where the “Red, White & Boom” fireworks show takes place, and Bde Maka Ska, the largest in the city’s Chain of Lakes.

The chief reported Saturday afternooon that “for the first time in recent years, we did not see widespread chaos involving groups recklessly firing fireworks at people and property. While gun violence remains a serious concern — and historically spikes during this week — the absence of dangerous fireworks activity is a clear reflection of the success of MPD’s holiday safety plan and the dedication of our officers.”

The chief credited “our proactive strategy” on July 4th with the arrest of a man downtown who had a pistol without having a permit to carry a firearm and the towing of a vehicle filled with illegal fireworks.
