Samuel Harris, 44 and known as JR, was shot multiple times and killed while walking his dog Tequilla near Mitchell Street SW and Joseph E. Lowery Boulevard in Atlanta on a February evening. Police arrived around 8:49 p.m., and Harris was pronounced dead at the scene; the dog was also killed during the encounter, which began as a robbery.

Investigators arrested two men in connection with the killing. Brandon Baker, 36, was taken into custody in April. In October authorities arrested a second suspect, 41-year-old Ricky Pierce. Both face charges that include murder, aggravated assault, armed robbery, and possession of a firearm during the commission of a felony; Pierce faces an additional gun charge. A third man arrested in April had his charges dismissed and was released in June.

Two people remain in custody and are awaiting trial for their alleged roles in the robbery and fatal shooting. Does anyone who knew Samuel or who was in that neighborhood that night have information to share?
