Herman Roberts was 22 when he was found shot to death in Creel Park in South Fulton, Atlanta, on October 10, 2017. Investigators determined he had been shot seven or eight times at close range. A father of two and an aspiring hip-hop artist, Roberts’ music equipment and personal effects — including his wallet, an iPad, and a computer used for his work — were missing from the scene.

Authorities have said he may have been lured to the park under the pretense of filming a music video and then ambushed, though his mother, Tonia Martin Roberts, doubts that story and believes he knew his assailants. Investigators have also considered an accusation that Roberts stole money as a possible motive. No arrests or publicly identified suspects have been announced and the investigation remains open.

If anyone has information about Herman Roberts, his movements before October 10, 2017, or the missing items, please come forward and share what you know.
