A Detroit block party last night ended in mayhem when a gunman fired into the crowd, killing a 20-year-old man and injuring nine others, the AP reports. One man is said to be critically wounded, while eight others ranging in age from 21 to 46 were "seriously injured," the news agency notes. Around 400 people were enjoying the evening, barbecuing and watching a basketball game, when shots rang out, with witnesses on the scene grabbing their kids and fleeing, leaving overturned strollers in their wake, ClickOnDetroit.com reports. "Through the grace of God, no children were shot," Detroit's assistant police chief says, per the AP. Authorities speculate the shooter was going after the dead man, the news agency notes, but it's been hard to gather info as the Detroit Free Press reports that party attendees aren't being cooperative with police.
Meanwhile, a shooting at a block party in Philadelphia left seven people injured last night, the AP reports—and per NBC Philadelphia, three of those injured were children. Lt. John Walker of the Philly Police says the gunman in this case apparently just started shooting in the street at around 10 last night, hitting anyone in his path. An 18-month-old girl was grazed on the neck by a bullet; also hit were an 11-year-old girl in the knee and shoulder, and a 13-year-old boy in the chest, per NBC. All three kids are said to be stable condition at Children's Hospital of Philadelphia.
