Stafford Woman Sentenced to 11 Years in Prison for Conspiracy to Distribute Hydromorphone, Oxycodone, and Oxymorphone

ALEXANDRIA, VA—Robin Anne Krohn, 31, of Stafford, Virginia, was sentenced today to 143 months in prison, followed by three years of supervised release for conspiracy to distribute controlled substances.

Dana J. Boente, U.S. Attorney for the Eastern District of Virginia; Adam S. Lee, Special Agent in Charge of the FBI’s Richmond Field Office; Andrew G. McCabe, Assistant Director in Charge of the FBI’s Washington Field Office; and Charles E. Jett, Stafford County Sheriff, made the announcement after sentencing by U.S. District Judge James C. Cacheris.

Krohn pleaded guilty on July 22, 2014. According to court documents, Krohn is a former patient of Dr. Nibedita Mohanty, who was indicted on charges of conspiracy to distribute controlled substances, distribution of controlled substances, aiding and abetting health care fraud, and aiding and abetting money laundering on July 24, 2014.

Krohn was a patient of Dr. Mohanty from approximately February 2010 through December 2011. During that time, Dr. Mohanty prescribed excessive dosages of controlled substances to Krohn. Krohn both abused the medication she was prescribed, snorting up to 150 pills per day, and distributed a large portion of the controlled substances prescribed by Dr. Mohanty for a profit, earning between $3,000—$5,000 per week throughout the course of the conspiracy.

Knowing that Dr. Mohanty freely prescribed excessive dosages of controlled substances, Krohn was also responsible for recruiting a number of individuals to see Dr. Mohanty in order to obtain unnecessary prescriptions, which Krohn and her conspirators would later abuse and distribute for profit.

This case was initiated and investigated by the Stafford County Sheriff’s Office and assisted by the FBI’s Richmond and Washington Field Offices. Assistant U.S. Attorney Gene Rossi and Special Assistant U.S. Attorneys Jennifer Ballantyne and Nicole Grosnoff prosecuted the case.
