Milwaukee police recovered the high-powered pellet gun used to wound four teenagers and a dog, but they don’t know who the shooter was. The victims were walking along the Hank Aaron Trail Wednesday at about 7:00 P-M they were targeted. They initially thought they were being hit by bullets. Police responded by combing the area with officers armed with long guns and bringing an armored vehicle to the location. The teenagers were treated at a hospital for injuries which weren’t life-threatening.
