Chicago police say separate weekend shootings across the city left at least 10 people dead and dozens wounded.
The violence peaked early Sunday with several shootings, including one in a courtyard on the city's South Side that left eight people wounded. The Chicago Sun-Times and WLS-TV compiled the shooting death totals.
Police Patrol Chief Fred Waller said Sunday that in some cases, gang members are using large summer crowds as cover. He says they "shoot into a crowd, no matter who they hit."
Chicago Police Superintendent Eddie Johnson planned a Monday news conference to discuss the violence.
Police have said violent crime has declined overall. Still, anti-violence protesters have recently shut down freeways in Chicago to voice their outrage.
