But murders were down 23% compared to same point a year ago, and the city tallied 19% fewer shooting incidents.
Most of the shootings are connected to gang violence in the city. In Chicago right now, police have more unsolved crimes than they do solve crimes.
Police arrested 46 people over the weekend for gun-related offenses and seized 60 firearms, adding to the total of 5,600 firearms seized in the city to date.
Chicago has recorded more than 300 murders so far in 2018, more than any other US city but about 100 fewer than the city had seen at this time previous year. Giuliani falsely stated that there were "63 murders" in Chicago this weekend, despite the reports that 63 were wounded and 11 killed.
Shooters, he said, targeted large groups of people at block parties, a funeral, and other outdoor events.
The youngest survivor is an 11-year-old shot in the leg.
Waller said the summer heat brings crowds out to the streets, particularly when violence has taken place.
The violence peaked early Sunday, including one shooting on the city's South Side that injured eight people.
Police Superintendent Eddie T. Johnson told reporters at a press conference on Monday that the weekend shootings were "not random" and instead were fueled by gang conflicts in the city.
Chicago, one of the most populous metropolitan areas in the United States, turned into what one paramedic described as a "war zone" over the weekend as 70 people were shot, eleven fatally, in multiple shootings across the city. Police said they've been working around the clock this weekend and that the department has seen a citywide reduction in shootings by 17 percent this year. "At no time did Stroger go on bypass or "lockdown" its trauma unit", the spokeswoman said.
Chicago's gun violence has drawn widespread attention, including from Mr Trump and his lawyer, Mr Giuliani, who blamed the problem on Chicago's long-time "Democratic rule" in a series of tweets on Sunday and Monday. While we shouldn't condone the use of tactics which close down infrastructure in the name of free speech, it's clear that the residents of the city have plenty to be upset about.
"We just have too many guns on the streets of Chicago".
