Seven people were shot in downtown Chicago over three hours early Sunday, including an attack in River North that wounded four people when someone fired from a car on State Street.

The mass shooting occurred around 1 a.m. in the 400 block of North State Street, the same block where two men were wounded in a drive-by shooting just two weeks ago.
