Montgomery County police arrested Dashiell for beating a 28-year-old man to death at a family gathering in Gaithersburg Saturday night.
According to NBC Washington, police responded to a report of an assault shortly before 11 p.m. at the 100 block of Steven Court. When they arrived, they found Justin Carter, 28, lying on the ground. Carter was taken to a hospital, where suffered blunt trauma injuries and died thereafter.
