SEVIERVILLE — An FBI investigation has resulted in drug charges against six Sevier County residents, according to documents filed this week in the federal district court in Knoxville.

Juan Lopez Gallardo; Jairo David Posadas, aka Alex Martinez; Josedad Delacruz, aka Mateo; Serguin Castro-Carias, aka Jose; Nolvia R. Carillo; and James Carroll Hickman were named in an indictment unsealed this week.

They are facing charges of possession of cocaine with intent to distribute and conspiracy to distribute cocaine.

The FBI was in Sevier County Thursday making arrests at several locations in Sevier County, although no information was made available on the charges until the indictment was unsealed Friday.

Both the FBI and U.S. Attorney General’s Office declined to comment on the case. Local law enforcement offices have also referred questions to the FBI.

But documents filed in federal court indicate the FBI launched an investigation into the group last spring using controlled buys, surveillance and other means to build a case against the group.

That includes controlled purchases of cocaine on more than a dozen occasions through the investigation.

At one point in 2020 they recorded a transaction involving the sale of eight grams of cocaine, according to the affidavit.

They got information last summer that the group was looking to buy “kilogram quantities” of cocaine, the documents said.

Court records show federal authorities are holding Posadas and Castro-Carias.

Records at the Sevier County Jail show that Delacruz, Castro-Carias, and Gallardo were held there Thursday before being transferred to another facility Friday. The records also show an individual named Jairo David Medrano was also held at the jail and transferred to another facility.
