Her lawyer, Jim McMillan, declined comment, the Daily News reported.
Federal authorities say Henry Butler was arrested after driving away from his Thousand Oaks, Calif., home on Aug. 3. He was accused of smuggling cocaine from Los Angeles to New York using overnight shipping.
While investigators were trying to get permission to search Butler's home, local police saw Daniels-Butler drive off in a Mercedes Benz, according to a federal complaint charging her with evidence tampering.
The police stopped her for a traffic violation and, with her consent, searched the car. Inside, they found a loaded semiautomatic handgun, an unloaded Tech-9 assault weapon, ammunition and $39,500 in alleged drug proceeds, the complaint said.
The name of Butler's attorney was not immediately available.
