Grady County deputies and Oklahoma Medical Marijuana Authority agents searched the Supreme Grow facility in the Alex area of Grady County and found 877 pounds of marijuana, about 398 kg.[1] The sheriff’s office valued the marijuana at about $745,000.[1]

Deputies arrested four people, who were held on Immigration and Customs Enforcement detainers.[1]

The joint investigation targeted illegal operations around Supreme Grow and began in September 2026.[1] Officials said the grow kept operating after its owner surrendered an Oklahoma Bureau of Narcotics and Dangerous Drugs marijuana grow licence.[1]

Officials said other suspects linked to Supreme Grow could face charges of trafficking a controlled dangerous substance, using surveillance equipment in a felony and conspiracy to commit a felony.[1]
