The case revolves around Florence Bikundi, who owned and operated a home health care agency, and a multimillion-dollar scheme to defraud the D.C. Medicaid program. Atawan Mundu John, the defendant in this case, was employed as a personal care aide at Bikundi’s agency. This scheme led to a federal grand jury indictment in December 2014.

Indictment and Charges

As part of the investigation into the healthcare fraud conspiracy, law enforcement agents conducted multiple interviews with the defendant, Atawan Mundu John. In June 2014, one of the Medicaid beneficiaries involved in the scheme placed a recorded call to John, which lasted approximately 18 minutes. During this call, John instructed the beneficiary to lie to the FBI about receiving money or kickbacks, fully aware of the ongoing federal investigation.

John was subsequently charged with one count of attempted witness tampering. In December 2014, a federal grand jury returned a superseding indictment, charging several individuals, including John, with various offenses related to the scheme to defraud Medicaid.

Recorded Call

The recorded call between John and the Medicaid beneficiary played a crucial role in the investigation. During the call, John admitted that paying money to beneficiaries was fraud, highlighting his involvement in the healthcare fraud conspiracy. This evidence further substantiated the charges against him.

Fugitive Status

Following the recorded call and before formal charges were brought against him, John fled the area. As a result, he became a fugitive and remained at large for almost nine years. Law enforcement agencies continued their efforts to locate and apprehend him during this time.

Arrest and Plea

After nearly a decade as a fugitive, John was finally arrested on July 13, 2023, in Maryland. He has been held without bond since his arrest. On the day of his arrest, John pleaded guilty to attempted witness tampering in relation to the healthcare fraud conspiracy.


The defendant’s guilty plea was accepted by U.S. District Court Judge Beryl A. Howell, who scheduled his sentencing for November 3, 2023. During the sentencing, the court will consider the applicable sentencing guidelines and other factors to determine an appropriate sentence for John.
