Four more members of the Anderson Drug Trafficking Organization pleaded guilty this week to federal charges of selling cocaine in the Broadway-Fillmore neighborhood.

The latest members of the family-run drug ring headed by Theresa Anderson to admit their guilt are Melvin Calhoun, her husband; Dion Anderson, her son; and Anquensha and Toshia Hodge, two of her daughters.

All four pleaded guilty to conspiracy to distribute cocaine base, joining Anderson and two other family members who previously pleaded guilty.

Assistant U.S. Attorney Melissa M. Marangola said Leo Mellerson, a boyfriend of one of the daughters and the last remaining defendant in the case, also is expected to take a plea deal.

The pleas are the result of an investigation by the Drug Enforcement Administration and State Police.
