Four years ago, Chicago didn't record 400 homicides until just before Thanksgiving Day. The city has already passed that mark this year.



Chicago is on pace to have a deadlier year than 2016, when gun violence reached levels not seen in 20 years, according to data kept by the Tribune. While fewer people have been shot this year, more of them are dying from their wounds.



An analysis of Tribune data shows the percentage of fatal shootings is running about 1.3 percent higher than last year. The percentage had been declining in recent years but started to rise last year.



In 2013, about 15.5 percent of those shot in Chicago died. That percentage dropped to around 14 percent the next two years, but rose in 2016 to 15.2 percent, according to Tribune data. So far this year, 16.5 percent of the 2,150 people shot have died.



Combined with other cases, such as strangulations and stabbings, the number of homicides reached 400 on Thursday, two days earlier than last year.
