Juan Martinez-Serrano, 29, was shot and killed on November 4, 2017, in Chicago’s Archer Heights neighborhood. His death occurred during a year when the city faced a sharp rise in gun violence; by August 2017 Chicago had recorded over 500 homicides, and community-level violence and gang activity were frequently cited as drivers of the violence in neighborhoods like Archer Heights.

Martinez-Serrano’s death was recorded alongside many others that year in local homicide records and memorial projects that document victims of gun violence. Did anyone in Archer Heights or who knew Juan see or hear anything that could help explain what happened that night?
