ST. LOUIS • Sixteen members of an alleged drug trafficking ring that distributed and sold heroin throughout St. Charles and Madison counties have been indicted on an assortment of federal charges.

Ten people were arrested in a Tuesday morning sweep by the FBI. They face charges of conspiracy to distribute heroin, firearms violations and money laundering. A total of 16 members of the alleged drug ring were indicted by a grand jury in September in U.S. District Court in St. Louis.

Four members were previously arrested and two remain at-large, the FBI said.

Cortez "Tez" White, 32, of Florissant, and Samantha Street, 23, of St. Louis County, allegedly served as the coordinators of the network, according to the charges, and used cellphones to oversee the trafficking and direct the drug runners. White also is charged with intent to distribute marijuana.

The group was responsible for the distribution of more than one kilogram of heroin, according to the indictment, then pocketed the profits.

Also arrested Tuesday were: Donald "Lil Don" White, 29, of St. Charles; Darnell "Lil Red" Lathan, 31, of Florissant; Charles Peoples, 31, of St. Louis; Reginald Davis, 33, of St. Louis County; Stephany "Ann" Fowler, 35, of St. Louis; Clarissa "Red" McCary, 36, of Florissant; Bridgett Corbett, 28, of O'Fallon, Mo.; and Philip Pratt, 26, of Pagedale.

The FBI continues to look for Orbia "Pops" Carthen, 52, of St. Louis County and Kevin Mulvill, 29, of Alton. Both were indicted with the others in September. Anyone with information about their location should call the FBI at 314-589-2500.

The investigation was launched in April 2009 after the FBI received a tip about the network. The FBI's Safe Streets Gang Task Force made the arrests in St. Louis, St. Louis County and St. Charles County.
