David J. Kartzmark, 25, was fatally shot on January 5, 2013, in the Humboldt Park neighborhood of Chicago. The shooting happened about 7 a.m. in the 1500 block of North Talman Avenue. Kartzmark was found with a gunshot wound to the chest and was pronounced dead while being transported to Norwegian-American Hospital.

His death was one of ten homicides recorded in Chicago during the first week of 2013, part of a surge that pushed the city’s homicide rate toward its highest level since 2008. That early-week spike underscored ongoing challenges for law enforcement and community leaders working to address gun violence in the city.

If anyone has information about Kartzmark’s killing or remembers activity in the 1500 block of North Talman Avenue that morning, please share what you know.
