Charles Diggs, 37, was shot and killed on Saturday, July 25, 2015, in the 1800 block of Saratoga Street in Baltimore. His death occurred during a summer 2015 surge in violence that produced a marked increase in homicides across the city.

The case remains one of several from that month that presented major challenges for investigators.

If anyone knew Charles, was in that neighborhood that day, or has information that could help, please come forward to assist the ongoing search for answers.
