Seven people were indicted Tuesday in a conspiracy to traffic cocaine between South Carolina and Mexico, according to the U.S. attorney office.

A grand jury in Charleston charged them with conspiring to distribute more than five kilograms of cocaine, according to U.S. Attorney for South Carolina Bill Nettles' office. The indictment alleges the conspiracy began in or around July 2011.

Those indicted were Jose Alfredo Sierra-Reynoso of Saint Matthews, Michael Clark (aka Bizzy B) of Holly Hill, Lonnell McFadden (aka June) of Holly Hill, Marion Jerome Mack (aka Jigga) of Holly Hill, Adryenne R. Johnson of Lexington, Allen Washington (aka Dirty) of Holly Hill and Harold Robinson of Holly Hill.

The indictment is the culmination of an Organized Crime Drug Enforcement Task Force investigation conducted by DEA Charleston Task Force, the Dorchester/Summerville Metro Narcotics Unit, HSI Border Enforcement Security Team and the State Law Enforcement Division.

More than 75 law enforcement officers from federal, state and local agencies executed arrest warrants and served search warrants in several South Carolina counties, according to the announcement.
