No one knew where he lived, what phone number he used, what car he drove," Kelly said. A call to Corley's lawyer wasn't immediately returned Thursday. The case was pieced together by Detective David Leonardi, who said the dealers used a language called the "5 percenter" where every number and letter had its own word and members decoded messages about drug orders. The wiretaps also netted information on illegal guns and a possible killing in South Carolina.
