A grand jury is mulling Nelly’s felony drug case and will soon decide whether to indict the rapper, BOSSIP has learned.

The Tennessee Highway Patrol arrested Nelly, real name Cornell Haynes and five other men outside Nashville last spring after a search of his tour bus turned up weed, molly, methamphetamine and several handguns.

Nelly denied any involvement with the drugs or the guns, but was charged with felony drug possession, possession of drug paraphernalia and simple possession of marijuana.

BOSSIP can reveal that Putnam County District Attorney Brian Dunaway is now moving forward with the drug case, which could put Nelly behind bars for eight to 12 years on the felony drug charge alone. Nelly’s case was sent to a grand jury Oct. 28, and they’ll have until Nelly’s next court date next month to officially charge him or throw the case out.

Convening a grand jury is the first major step in the Nelly’s case being brought to trial. During the grand jury hearings, which are closed to the public, the jurors will hear from witnesses and review evidence to figure out if they should indict Nelly.
