Increase In Violence In Chicago Weeks Ahead Of Mass Shooting

Much of Illinois' gun violence can be linked to weapons coming in from neighboring states with weaker gun laws and restrictions.

After the July 4 mass shooting in Highland Park, a suburb a few miles north of Chicago, Chicago Mayor Lori Lightfoot offered to help. On Twitter, she said, "we grieve with the families of the deceased and injured. Law enforcement is working hard to bring the shooter into custody."

The city of Chicago is all too familiar with gun violence. That same July 4 weekend police saw more than 60 people shot in the city. 

That weekend's tally included a woman killed in a popular tourist spot — Chicago's Chinatown, in what local media called a shootout near a karaoke bar.
