When the ship arrived in Baltimore on December 18, the documents state, the three men had planned to deliver those drugs at the Port Covington Wal-Mart, near the cruise terminal, to Loxly Johnson and Shenika Nicole Graves, who appear to have driven to Baltimore from Virginia. Johnson, also known as Desmond Williams, is a Jamaican citizen and a legal permanent resident of the United States, according to the documents. He, Excell and Graves were indicted by a grand jury on charges of conspiring to import drugs into the country. Customs officials were tipped off by Elhadad David, a ship security officer for Royal Caribbean.
