At least four major U.S. cities were reeling from an onslaught of mass shootings over the weekend that left at least 38 people wounded, six dead and police officials alarmed that the surge in gun violence is a prelude to a bloody summer as the nation emerges from the pandemic.

Police in Austin, Cleveland, Chicago and Savannah were all investigating on Sunday mass shootings that erupted over a six-hour streak that began around 9 p.m. on Friday and spilled over into Saturday morning.

"It’s very disturbing what we’re seeing across the country and the level of gun violence that we’re seeing across the country. It’s disturbing and it’s senseless," Savannah Police Chief Roy Minter, Jr. said at a weekend news conference after one person was killed and eight others, including an 18-month-old baby and two teenagers, were wounded.

On Sunday morning, Savannah police were working to identify the suspect or suspects who rolled up in a dark-colored sedan and unleashed a barrage of gunfire around 9 p.m. Friday on a group of people standing in front of a home in a residential neighborhood of east Savannah. Minter identified a 20-year-old man killed in the ambush as Arthur Milton of Savannah.
