The tally doesn't count a woman run over on Lake Shore Drive early Sunday. Her boyfriend, who also was hit in traffic, told police they were fleeing a group of armed robbers, and detectives have located evidence of a group of men in the area.



By Tuesday morning, the tally of those shot in Chicago this year was around 1,500, according to data compiled by the Tribune, with at least 250 killed. By this time last year, 957 had been shot, with 164 killed.



So far, shootings are up more than 50 percent this year, although the pace of increased violence had slowed from earlier this year, when Chicago was on track to see shooting victims nearly double.



Chicago police have said the violence has been fueled by gang conflicts and a proliferation of guns, mixed with weak gun law enforcement. The department has blamed most of the violence on a core group of about 1,300 people whom they have used data analytics to pinpoint. The department has called them "strategic subjects."



It can be tougher to pinpoint exactly when that violence can explode, with spikes that can spring up on any warm weekend. Over Mother's Day weekend, more than 50 people were shot, eight fatally, in the most violent weekend in Chicago since September.



The 60 homicides this month have outpaced those in each of the previous three years in Chicago, according to Tribune data. By May 30, 2015, there had been 45 homicides, with 41 by the same date in 2014 and 47 in 2013.
