Two Dallas residents, Corey Buchea Grant and Calvin Autae Thompson, have been convicted of conspiracy to distribute and possess with intent to distribute heroin and crack cocaine in the Eastern District of Texas. The verdict was delivered by a jury after a six-day trial before U.S. District Judge Sean D. Jordan on November 3, 2025, according to Acting U.S. Attorney Jay R. Combs.
Court proceedings revealed that Grant operated at a "trap house" in East Dallas managed by Thompson. The location was used for selling various drugs including heroin, cocaine, crack cocaine, and heroin laced with fentanyl. Authorities believe drugs supplied by Grant and Thompson contributed to a fentanyl overdose death in Lewisville, Texas.
Prosecutors described how drug dealers would acquire narcotics from these Dallas locations for distribution throughout the Eastern District of Texas. Evidence presented during the trial included cell phone messages, social media communications, location data from phones, financial documents, and testimony from cooperating defendants.
Grant and Thompson could each face up to life in federal prison at sentencing. The statutory maximum sentences are determined by Congress; however, the actual sentence will be set by the court after considering advisory guidelines and other legal factors following a presentence investigation conducted by the U.S. Probation Office.
The prosecution is part of Operation Take Back America—a national effort led by the Department of Justice aiming to combat illegal immigration, dismantle cartels and transnational criminal organizations (TCOs), and address violent crime through coordinated use of resources from programs such as Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
The investigation involved multiple agencies: 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. Assistant U.S. Attorneys Heather Rattan and Eric Erlandson prosecuted the case.
"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," said officials.
A sentencing hearing date will be scheduled after completion of further investigation.
