Inmate Sentenced for Drug Conspiracy While Serving Time for Prior Drug Cases

TULSA, Okla. – A man serving twenty years in the Oklahoma Department of Corrections for several prior drug offenses was sentenced today for federal Drug Conspiracy charges, announced U.S. Attorney Clint Johnson.

U.S. District Judge Sara E. Hill sentenced Shane Eugene Miller, 39, to 252 months followed by five years of supervised release.

“Miller ran an extensive drug conspiracy from prison with the aid of contraband cell phones and other co-conspirators,” said U.S. Attorney Clint Johnson.  “The use of a contraband cellphone by prisoners cannot be tolerated.  The actions of Miller threatened our communities with dangerous narcotics.  My office, in conjunction with our law enforcement partners, will continue to prosecute individuals who deal drugs, whether they are in prison or out.”

“This investigation demonstrates the FBI’s commitment to ensuring those who pollute our communities with dangerous drugs are brought to justice,” said FBI Oklahoma City Special Agent in Charge Doug Goodwater. “We will continue to work side by side with our law enforcement partners to dismantle criminal enterprises, regardless of where they operate.”

Miller conspired with others to operate a drug conspiracy while in custody at the Department of Corrections. Court documents show that Miller used contraband cellphones to communicate about the drug distribution of methamphetamine and fentanyl. Miller further directed others to negotiate with buyers and collect payments. 

Brenda Raelene Blakeley, 65, of Oklahoma City, was sentenced in March 2025 for Possession of Methamphetamine with Intent to Distribute. Judge Hill ordered Blakeley to 235 months imprisonment, followed by five years supervised release. Blakely was stopped by law enforcement in 2023. Officers found methamphetamine concealed in the vehicle.

Cierra Michelle Warner, 32, of Ponca City, was sentenced in March 2025 for Use of a Communication Facility in Committing, Causing, and facilitating the Commission of a Drug Trafficking Felony. Judge Hill ordered Warner to 24 months imprisonment, followed by one year of supervised release. Warner helped communicate with co-conspirators to coordinate the distribution of fentanyl.

Johnathan Allen Perryman, 43, pleaded guilty to Distribution of Fentanyl and is awaiting sentencing.

Miller will remain in custody pending transfer to the U.S. Bureau of Prisons.

The FBI, the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Muscogee Creek Nation Lighthorse Police, and the Tulsa Police Department investigated the case. Assistant U.S. Attorneys Adam Bailey, Attila Bogdan, and Joel-lyn McCormick prosecuted the case.

The case was investigated under the Organized Crime Drug Enforcement Task Forces (OCDETF).
