James Pierre, 52, unlawfully prescribed pills to people posing as patients at West Parker Medical Clinic, a Houston pill factory, from June 2015 to July 2016, court documents show.

Pierre, along with his medical assistant, wrote hundreds of people illegal prescriptions for hydrocodone and carisoprodol, a combination of controlled substances known as the “Las Vegas cocktail,” according to the trial.

So-called “runners” tricked scores of people into posing as West Parker patients, paying about $220 to $500 in cash for each visit in exchange for prescriptions, investigators said.

Throughout the program, West Parker made approximately $1,750,000 from prescriptions, according to investigators, and over $300,000 went to Pierre.

Pierre is convicted of one count of conspiracy to illegally distribute and dispense controlled substances and seven counts of illegal distribution and dispensing of controlled substances.

Pierre is due to be sentenced on June 27 and faces up to 20 years in prison for each charge.

To date, a co-conspirator has pleaded guilty to conspiring to unlawfully distribute controlled substances, officials said.

Assistant Attorney General Kenneth A. Polite Jr. of the Justice Department’s Criminal Division; US Attorney Jennifer Lowery for the Southern District of Texas; and Special Agent in Charge Daniel C. Comeaux of the DEA’s Houston Division made the announcement.

DEA Houston was investigating the case.
