Robert Jr. Gardner was 28 when he was found shot and killed in Baltimore, Maryland, on June 28, 2017. The killing happened outdoors in a high-crime area during a summer that saw a sharp rise in homicides across the city, most involving firearms.

Investigators faced barriers common to many cases from that period: incidents occurring in public spaces, few willing witnesses, community mistrust of police, and staffing shortages. No suspects have been publicly identified and no arrests have been announced in Gardner’s case.

Did anyone in Baltimore know Robert Jr. Gardner, or does anyone have information that could help bring answers in this unsolved homicide?
