Tremayne Franklin, a 33-year-old Chicago resident, was killed in a shooting on November 30, 2012. His death came amid a sharp rise in violence across the city that year, when Chicago recorded 506 homicides — the first time since 2008 the count exceeded 500.

2012’s spike in killings was linked in reporting to unusually warm weather and changes in policing strategies. That March set a record for warmth and saw 53 homicides, and the city also dismantled specialized gang units as the police department shifted toward community policing. Franklin’s shooting occurred during a weekend when multiple people were shot, reflecting the wider problem of gun and gang-related violence and strained local resources.

If anyone has information about Franklin’s death or remembers events from that weekend in late November 2012, please come forward.
