Dallas men convicted in East Texas federal drug trafficking conspiracy

PLANO, Texas – Two Dallas men were found guilty of federal drug trafficking violations in the Eastern District of Texas, announced Acting U.S. Attorney Jay R. Combs.

Corey Buchea Grant, 31, and Calvin Autae Thompson, 36, were found guilty by a jury of conspiracy to distribute and possess with intent to distribute heroin and crack cocaine following a six-day trial before U.S. District Judge Sean D. Jordan on November 3, 2025.

According to information presented in court, Grant worked at a “trap house” in East Dallas, which was managed by Thompson, where multiple types of drugs were sold, to include heroin, cocaine, crack cocaine, and heroin laced with fentanyl. Drugs supplied by the two were believed to be responsible for a fentanyl overdose death in Lewisville, Texas.

According to information presented by prosecutors, drug dealers went to the Dallas “trap houses” to purchase the drugs, which would then be distributed in the Eastern District of Texas. Evidence presented by the court included cell phone messages, social media messages, cell phone location data, financial records, and testimony of cooperating defendants.

At sentencing, Grant and Thompson face up to life in federal prison.  The statutory maximum sentence prescribed by Congress is provided here for information purposes, as the sentencing will be determined by the court based on the advisory sentencing guidelines and other statutory factors. A sentencing hearing will be scheduled after the completion of a presentence investigation by the U.S. Probation Office.

This case is part of Operation Take Back America a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).

The case was investigated by the U.S. Postal Inspection Service, Internal Revenue Service – Criminal Investigations, U.S. Marshals Service, Dallas Police Department, U.S. Secret Service’s Dallas Digital Evidence Forensics Lab, Lewisville Police Department, and the Drug Enforcement Administration. This case was prosecuted by Assistant U.S. Attorneys Heather Rattan and Eric Erlandson.
