Priscilla M Mercado, 28, was fatally shot on April 7, 2012, in the Brighton Park neighborhood of Chicago. Reports indicate she was shot in a porch or hallway area, a reminder that gun violence in 2012 often happened close to victims’ homes and in their own neighborhoods.

Her death occurred during a year when Chicago saw a sharp rise in homicides and gun-related killings, with more than 500 homicides recorded in the city by year’s end.

Does anyone have information about Mercado, her last known whereabouts, or the circumstances on April 7, 2012 that could help shed light on what happened?
