A central Illinois woman and her son are charged with conspiracy to manufacture and distribute methamphetamine, according to federal prosecutors.

U.S. Magistrate Jonathan Hawley ordered Denise Taylor of Mason City held by the U.S. Marshals Service and set a detention hearing for Oct. 9. Her son, 23-year-old Brendin L. Williams, is in the custody of the Illinois Department of Corrections and is scheduled to appear in court with his mother.

U.S. Attorney for the Central District of Illinois Jim Lewis said Wednesday that Taylor was arrested Tuesday. He did not give details of the case against the woman and her son. However, Lewis said the two allegedly distributed more than 500 grams of methamphetamine from 2010 to September 2014.

It wasn't immediately known if Williams or Taylor have legal representation.
