Houston Man Sentenced to 25 Years in Federal Prison for Counterfeit Drug Trafficking and Money Laundering

Byron A. Marshall, a 45-year-old resident of Houston, has been sentenced to federal prison for his involvement in a counterfeit drug trafficking and money laundering scheme. The announcement was made today by U.S. Attorney Damien M. Diggs of the Eastern District of Texas.

Marshall pleaded guilty to charges of conspiracy, trafficking in counterfeit drugs, and money laundering conspiracy. U.S. District Judge Marcia A. Crone handed down a sentence of 300 months in federal prison.

The indictment against Marshall outlined his involvement in the scheme, which spanned from April 2014 to August 2021. Marshall collaborated with ten others, including Adam P. Runsdorf, the owner and president of Woodfield Pharmaceutical LLC, a company based in Boca Raton, Florida.

According to information presented in court, Marshall utilized Woodfield Pharmaceutical’s manufacturing facility and employees in Houston to produce more than 500,000 pints of counterfeit cough syrup. Marshall’s drug trafficking organization sold the counterfeit drugs across Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina, Tennessee, Wisconsin, California, Florida, Arkansas, and Ohio. Prices generally ranged from $100 to more than $1,000 per one-pint bottle. Depending on the market and brand of cough syrup, prices went as high as $3,800 to $4,000 per pint.

During the conspiracy, Marshall communicated directly with Runsdorf regarding production of the counterfeit cough syrup.  At Runsdorf’s request, Marshall paid Woodfield Pharmaceutical in cash only, and Woodfield employees mailed the cash directly to Runsdorf in Boca Raton. 

“Mr. Marshall was the ringleader of a drug trafficking organization responsible for selling counterfeit drugs across most of the southeastern United States and many other states,” said U.S. Attorney Damien M. Diggs.  “Drug trafficking organizations like this are a cancer to our nation and present a substantial threat to our communities.  Today’s significant sentence should send a clear message to such organizations that the Eastern District of Texas along with our federal, state, and local law enforcement partners will remain laser-focused on crippling drug trafficking organizations that choose to distribute drugs and other poisons in our communities.”       

All eleven defendants charged in the indictment pleaded guilty.  Eight have been sentenced including Marshall. Adam Runsdorf and Tunji Campbell pleaded guilty to conspiracy, trafficking in counterfeit drugs, and money laundering conspiracy. Campbell, who partnered with Marshall to hatch the scheme, was sentenced to 135 months imprisonment. Runsdorf was sentenced to 72 months imprisonment and ordered to forfeit $5 million and a McLaren sportscar. Chauntell D. Brown pleaded guilty to conspiracy and trafficking in counterfeit drugs and was sentenced to 72 months imprisonment. Cheryl A. Anderson, Ashley A. Rhea, Maria Anzures-Camarena and Kalpen Patel, each pleaded guilty to conspiracy and were sentenced to 60 months imprisonment. Three others are awaiting sentencing.
