A federal grand jury has returned a 17-count superseding indictment that prosecutors say traces a major meth operation straight back to a Tennessee prison cell. The indictment, handed up on June 17, 2026, charges 11 people in a methamphetamine trafficking conspiracy alleged to have pumped large quantities of the drug across southern Middle Tennessee, with Lawrenceburg and Pulaski at the center of the action. Court filings say contraband cell phones were the lifeline of the ring, used to coordinate distributors and runners, and that the accused ringleader worked with his sister on the outside and a roster of local residents to move product across multiple counties.
According to a press release from the U.S. Attorney’s Office for the Middle District of Tennessee, 38-year-old Corey Byrd is alleged to have directed much of the conspiracy from a Tennessee Department of Correction cell by using smuggled cell phones between 2023 and August 2025. Prosecutors say the superseding indictment includes 17 counts and seeks forfeiture of six firearms allegedly connected to the offenses. The announcement credits the FBI Nashville Field Office, the Tennessee Bureau of Investigation, the Pulaski Police Department, the Giles County Sheriff’s Office and the Lawrence County Sheriff’s Office with teaming up on the investigation.
Local coverage from WSMV lists the defendants named in the superseding indictment, including Corey Byrd; his sister, Tiffany Byrd of Lawrenceburg; Robert Miles of Lawrenceburg; and several residents of Pulaski. That report notes that each of the nine other defendants is accused of trafficking at least 500 grams of methamphetamine. WSMV also reports that prosecutors allege Robert Miles possessed more than 500 grams of meth, fentanyl and a firearm during an August 28, 2025 incident, and that Assistant U.S. Attorney Zachary T. Hinkle will prosecute the case.
Indictment Outlines Multi-kilogram Meth Ring And Weapons Counts
The U.S. Attorney’s Office says the superseding indictment alleges that the conspiracy ran from at least 2023 through August 2025 and that members distributed 500 grams or more of methamphetamine. Defendants charged with conspiring to distribute 500 grams or more face potential penalties that can include life in prison, depending on the quantity proven at trial. The firearm charge tied to the August 28, 2025 seizure carries a mandatory minimum five-year sentence that must be served consecutively to any other prison term. Prosecutors say the government is also seeking forfeiture of firearms and other assets allegedly linked to the trafficking operation, according to the U.S. Attorney’s Office for the Middle District of Tennessee.
How Investigators Say The Prison-Based Ring Worked
Prosecutors and local reporting describe Byrd as allegedly running a kind of command-and-control center from behind bars, using contraband cell phones in his prison cell to direct the operation. Outside coordinators, including his sister, are accused of handling purchases, assigning runners and managing the money flow. WSMV reports that Tiffany Byrd served as a primary outside contact who distributed methamphetamine to sub-distributors and directed street-level couriers. Authorities say the network depended on a core group of higher-level distributors who broke down larger drug shipments and passed them to smaller operators working in and around Lawrenceburg and Pulaski.
What Comes Next
All 11 defendants are presumed innocent unless and until proven guilty in court. An indictment is a set of allegations, not a finding of guilt. The assigned federal prosecutor, identified in local reporting as Assistant U.S. Attorney Zachary T. Hinkle, will guide the case through the Middle District of Tennessee’s docket and may seek asset forfeiture tied to the alleged drug proceeds and firearms. Local officials say the case highlights ongoing worries about contraband cell phones inside correctional facilities and the role those devices can play in keeping organized drug operations alive even after key players are locked up.
