At least 29 people were wounded and three people -- including a 16-year-old boy -- were killed by gun violence during another bloody Chicago weekend.
Jamal Lockett, 16, was fatally shot in the chest Saturday afternoon in the city's South Shore neighborhood. CBS Chicago reports that, according to police, Jamal was arguing with other young men about whether a bicycle had been stolen.
Community activist Andrew Holmes was handing out flyers near the crime scene, urging area residents to contact police if they have any information about the fatal shooting.
"These kids need to graduate instead of being buried," Holmes told CBS. "They just need to graduate. So I carry this cap and gown to remind parents."
Also killed over the weekend in Chicago were Jeremiah Arnold, 26, and Andre Brown, 33, the Chicago Sun-Times reports.
Meanwhile, at least 29 people were injured by shootings between Friday evening and late Sunday. One man was shot in the back Sunday evening, while another was grazed in the face in the city's Chatham neighborhood around 10:50 p.m. in the 700 block of East 79th Street, the Chicago Tribune reports.
No arrests have been made to date in the shootings.
Last weekend, over the Memorial Day holiday weekend, 10 people were killed and more than 40 people were wounded in Chicago. Among those killed was a 14-year-old boy who had been eating pizza with his sister in the city's Uptown neighborhood. Andre Alejandro, 22, was charged last week in the fatal pizzeria shooting.
Homicides in the city so far this year are up nearly 50 percent compared to 2011.
The violent weekend prompted Mayor Rahm Emanuel and Chicago Police Superintendent Garry McCarthy to discuss the city's anti-gang strategy, which includes the targeting of "problem" liquor and convenience stores the mayor believes are serving as a catalyst for crime.
A rally in the city's Austin neighborhood Sunday, hosted by anti-violence group CeaseFire, addressed the upsurge of fatal gun violence in Chicago thus far this year. Participants urged area residents to help look out for each other and to stay safe, ABC Chicago reports.
"We are going to help them understand that violence is not good behavior and that it should not be the norm in the community," Tio Hardiman of CeaseFire, also a HuffPost Chicago blogger, told ABC.
