WORCESTER, Mass. (AP) — A Massachusetts man previously charged for attempting to use a wheelchair to smuggle cocaine now faces additional drug charges.

Emmanuelli Rojas-Moraza, 40, was held without bail in federal court Thursday for allegedly signing for a kilo of cocaine shipped to his Clinton home, the Telegram & Gazette reported.

The defendant's lawyer described him in 2014 as a mentally disabled drug mule for murderous Dominican drug lords. Rojas-Moraza was arrested on state narcotic charges last month after authorities reported intercepting a kilo of cocaine sent to his address for the second time in nine months.

Assistant U.S. Attorney John T. Mulcahy said Thursday he expected those charges would be dismissed following the federal charge.

A U.S. Postal inspector alleged that Rojas-Moraza signed for the drugs during a sting operation conducted Jan. 24, according to an affidavit filed in U.S. District Court in Worcester.

He is currently charged with possession with intent to distribute cocaine, which carries a sentence of up to 20 years in federal prison.

Rojas-Moraza’s lawyer, Joseph F. Hennessey, said outside the courtroom that he couldn’t immediately comment on whether his client planned to use mental health in his defense.
