Among those killed was 7-year-old Amari Brown, shot in the chest as he watched fireworks near his father's home in Humboldt Park late Saturday night. Police say they believe the attack was aimed at the father, whom they described as a ranking gang member.
Also gunned down was 17-year-old Vonzell Banks, who was shot as he played basketball Friday at a park named for Hadiya Pendleton, a high school student fatally shot in 2013 near President Barack Obama's Chicago home.
The wounded included a 16-year-old boy and a 15-year-old girl shot shortly after midnight Sunday as they walked in Old Town, and a 19-year-old man shot around 10 pm Saturday as two groups fought near Navy Pier after the fireworks display there.
The violence peaked from dusk Saturday until dawn Sunday, when 30 people were shot across Chicago -- nearly half the total for the entire weekend, measured from 3 pm Thursday until just before dawn Monday, Chicago Tribune reported.
Last Fourth of July, 82 people were shot, 16 of them fatally, over 84 hours. Five of those shot were wounded by police. There were no police-involved shootings this year.
The shootings this Fourth of July were primarily scattered across the South and West sides.
Englewood -- the police district with more shootings than any other in the city so far this year -- did not have a single person shot over the holiday weekend.
A number of other neighborhoods saw several shootings: Little Village, four people shot; Back of the Yards, six shot; and the Austin neighborhood, eight people shot.
Two North Side neighborhoods -- Old Irving Park and Albany Park -- each had shootings in which three people were wounded. One man died in the Albany Park shooting.
