The three men — Dominic Davis, Akeem Mapp, and James Paul — were arrested in June after a joint investigation by the Watertown Police and the Suburban Middlesex County Drug Task Force. Their home was raided by a NEMLEC SWAT team. The raid found cocaine, methamphetamine, ecstasy (MDMA), Ketamine, marijuana, three firearms, and approximately $10,000 in cash. This week, the Middlesex DA’s office announced the indictments from Nov.
