The arrests came after members of the LCSO Tactical Enforcement Unit and the Special Operations Section conducted a traffic stop and search warrants in Inwood, West Virginia, and in Leesburg on June 13.

During the course of the investigation, which began in March, one of the suspects sold an AR-15-style rifle during a controlled operation, according to the sheriff's office. The firearm is in the possession of the Loudoun County Sheriff’s Office.

Jeremy E. Black, 30, and Lindsey M. Siford, 32, both of West Virginia, were taken into custody June 13 after the traffic stop on Route 9 near Hillsboro. Both Black and Sifford had a concealed firearm in their possession, and approximately eight grams of cocaine and drug paraphernalia were also found inside the vehicle.

Black was charged with four counts of distribution of a schedule II narcotic and three counts of possession of a firearm while distributing a schedule II narcotic.

Siford was charged with two counts of distribution of a schedule II narcotic and one count of possession of a firearm while distributing a schedule II narcotic.

Following the traffic stop, a search warrant was conducted at a residence associated with the investigation on Belmont Drive in Leesburg, according to the LCSO. Inside the home, 92 grams of cocaine and other suspected narcotics and narcotics distribution products were located. A resident inside the home, Andrew O. Nickle, IV, 24, was charged with two counts of distribution of a schedule II narcotic, one count of a possession of a firearm while distributing a schedule II narcotic, and two counts of possession with intent to distribute a schedule II narcotic.

A search warrant was also conducted at Black’s home in Inwood, West Virginia, with the assistance of the West Virginia State Police.

Additional charges are pending against all three suspects, all of whom remain held at the Loudoun County Adult Detention Center without bond.
