An Upper Marlboro man was sentenced to eight years in federal prison and ordered to pay $20.85 million in restitution for his role in a money laundering scheme, officials said.

Adanegbe Osemwenkhae, 41, took on a managerial role in a major money laundering scheme from 2020-24, the Department of Justice said in a news release Wednesday.

Osemwenkhae and other conspirators were accused of laundering over $20 million in stolen money from about 15 victims, including a county government, a school district, a college and a medical center.

The release states that Osemwenkhae “used and controlled several different encrypted electronic communication accounts to supervise and manage the money laundering conspiracy.”

“Osemwenkhae directed and worked with members of the conspiracy to create limited liability companies to serve as shell entities; open bank accounts and/or cause bank accounts to be opened in the name of their shell entity; and receive and launder fraud proceeds,” officials said.

He also “helped coordinate the flow of fraudulent proceeds through various bank accounts” and determined how to split funds among those involved in the conspiracy.

Osemwenkhae pleaded guilty in April 2025 to serving as a manager and supervisor of the money laundering conspiracy.

Judge Matthew Maddox imposed the sentence, which also includes one year of supervised release, Wednesday.

Osemwenkhae is one of 14 people in two cases charged in the scheme. Others include Lakeisha Parker of Baltimore; Kevin Colon of Curtis Bay; Victor Killen of Hyattsville; Fatoumata Boiro of Largo; Martin Ogisi of Severn; and Emily Gil Arias, Lorena Perez Herrera, Yahya Sowe and Blondel Ndjouandjouaka, all of Silver Spring.

Many of them have received federal prison sentences and owe millions of dollars in restitution.
