Two accused of receiving cocaine in mail

A man and a woman pleaded not guilty Wednesday to charges of trafficking in cocaine after they allegedly accepted Express Mail envelopes containing kilo-sized packages of the white powder, said Suffolk District Attorney Daniel F. Conley’s office. Robert Conley, 46, and Myisha Wilkerson, 29, both of Dorchester, were arraigned in Dorchester Municipal Court on charges of trafficking in more than 200 grams of cocaine and conspiracy to violate the state’s drug laws, prosecutors said. Conley is additionally being charged with unlawful possession of a firearm and ammunition for the unregistered .38-caliber Colt revolver allegedly found when he was arrested.
