Police say they believe a fight over candy preceded the slaying of an Atlanta rapper over the weekend. Mario Hamilton, also known as Slim Dunkin, was killed at a recording studio on Memorial Drive on Friday night. Police said Hamilton got into an argument with another man prior to his death. “This fight spilled out into this area where he was attacked and bear. Based on the evidence we have, whoever he was fighting with secured a weapon and shot him,” Detective David Quinn of the Atlanta Police Department said. So far, no witnesses have come forward.
