ABINGDON, Va. - Seven people who conspired with doctors, including an Annandale-based doctor convicted of distributing more than 7,000 oxycodone pills, 34,000 milliliters of hydrocodone-chlorpheniramine solution (also known as "Tussionex"), and 107,000 milliliters of promethazine-codeine solution, were arrested this week.

A federal grand jury sitting in Abingdon indicted those arrested on August 26, 2025. Arrested this week were: Obioma Alozie Ndubuka, a.k.a. "Bankroll," 31, of Gaithersburg, Maryland; Raymono Alfonzo Russell II, 24, of Bowie, Maryland; Cameron Isaiah Lewis, 23, of Bowie, Maryland; Elhadj Malick Diallo, 31, of Silver Spring, Maryland; Zion Oluwademilade Adeduwon, 24, of Bowie, Maryland; Kenechukwu Brian Okwara, a.k.a. "Kene," 29, of Bowie, Maryland; and Yared Michael Tesfaye, a.k.a. "Yar," 28, of Montgomery Village, Maryland.

The grand jury has charged all seven defendants with conspiracy to distribute and possess with the intent to distribute oxycodone and hydrocodone-chlorpheniramine solution and obtaining promethazine-codeine solution by fraud, two counts of possessing with the intent to distribute hydrocodone-chlorpheniramine solution, and four counts of obtaining drugs by fraud.

According to court documents, in at least 2023 and 2024, Rotimi Iluyomade, and the named co-conspirators entered into an agreement to distribute more than 7,000 oxycodone pills and more than 34,000 milliliters of hydrocodone-chlorpheniramine solution to individuals in multiple states. In addition, the co-conspirators agreed to acquire and obtain promethazine-codeine solution by fraud.

As part of the conspiracy, multiple individuals visited Iluyomade's medical clinic to obtain fraudulent prescriptions for promethazine-codeine solution, as well as fraudulent prescriptions for oxycodone pills and hydrocodone-chlorpheniramine solution, also known as "Tussionex." The individuals provided Iluyomade with lists of multiple "patients" with fake identifying information or different variations of names and false addresses, and requested prescriptions be sent to pharmacies throughout the United States for the "patients" on the lists. At least 70 of the illegal controlled substance prescriptions were transmitted to and/or filled at pharmacies in the Western District of Virginia.

The Drug Enforcement Administration, the Federal Bureau of Investigation, the Virginia State Police, the Salisbury, Maryland Police Department, the Loudoun County Sheriff's Office, the Russell County Sheriff's Office, Nebraska State Police, HHS-OIG, and the Food and Drug Administration (FDA) are investigating the case.

Valuable assistance was provided by the United States Attorney's Office for the District of Maryland (Greenbelt Division) and Maryland Department of Public Safety and Correctional Services.

Assistant U.S. Attorneys Lena Busscher and Randy Ramseyer are prosecuting the case.

Acting United States Attorney Robert N. Tracci and Special Agent in Charge Reid Davis of the FBI Washington Field Office's Criminal Division made the announcement.

An indictment is merely an accusation. The defendant is presumed innocent until proven guilty.
