Police sources tell CBS Philadelphia the shots rang out a little after 4 a.m. on the 1100 block of South 11th Street. Some gunshot victims were rushed to various area hospitals by Philadelphia medics while some arrived in private vehicles.

Around 11 p.m., people were exiting a venue in the River North neighborhood and standing on the sidewalk when a vehicle pulled up and someone in the car opened fire on the crowd, Chicago Police Superintendent Larry Snelling said at a news conference.

One juvenile died in the hospital and, what police believe, might be another is dead at the scene of a mass shooting in downtown Indianapolis. Indianapolis Metropolitan Police Department officers say that 7 people were injured in one mass shooting near Illinois and Washington streets,
