Early on the morning of Thursday, April 23, dozens of federal, county, and local law enforcement agencies converged on the DHA Enterprises marijuana grow facility located just south of Hennessey at 6925 U.S. Highway 81, just north of the intersection of E650 Road (Exxon Road) and Highway 81 on the east side.
According to a media release from the U.S. Department of Justice, a federal drug investigation with ties to Hennessey has resulted in a sweeping indictment involving dozens of suspects connected to a nationwide black-market marijuana operation.
A federal grand jury unsealed the indictment on April 21, 2026, charging 51 defendants across 67 counts. The case alleges a large-scale conspiracy to grow and distribute illegal marijuana across multiple states, with Hennessey among several Oklahoma communities linked to the activity.
According to investigators, the operation ran from March 2025 through April 2026. Marijuana was allegedly produced at grow sites in locations including Hennessey, then distributed across the country to states such as Texas, Mississippi, Kansas, and North Carolina.
In a coordinated takedown, more than 100 law enforcement personnel executed arrests and search warrants across Oklahoma and beyond. Of the 51 individuals charged, 28 have been arrested, while 23 remain at large.
Authorities report seizing approximately 61,000 marijuana plants and more than 550 kilograms of processed marijuana during the operation.
Prosecutors allege the network included grow operators, brokers, and transporters working together to move marijuana through stash houses and into illegal markets across state lines.
The investigation involved multiple agencies, including the Homeland Security, DEA, Oklahoma Bureau of Narcotics, FBI, U.S. Marshals Service, EPA, the Kingfisher County Sheriff’s Office, Hennessey Police Department, and others.
