For Immediate Release
U.S. Attorney's Office, District of Nevada

LAS VEGAS – A federal jury convicted a purported medical assistant for the distribution of large quantities of illegal prescriptions for opioids without a legitimate medical purpose.

According to court documents and evidence presented during the eight-day trial, David A. Litwin (64) conspired with a licensed physician and others to sell prescriptions, including oxycodone, hydrocodone, Xanax and Soma, to persons without any legitimate medical purpose for the drugs. Over the course of several years, Litwin helped to operate a medical practice known as New Amsterdam Medical Group that purported to be a pain specialty center. However, Litwin and his co-conspirators utilized that pain specialty center to sell fake prescriptions to hundreds of people, including multiple individuals who filled the prescriptions in order to sell opioids unlawfully on the secondary market.

On September 22, 2023, Litwin was found guilty of conspiracy to distribute oxycodone and seven counts of distribution of oxycodone. United States District Judge Kent J. Dawson presided over the jury trial, and sentencing is scheduled for December 21, 2023.

United States Attorney Jason M. Frierson for the District of Nevada, Assistant Special Agent in Charge Kevin Adams for the DEA Las Vegas District Office, and Special Agent in Charge Spencer L. Evans for the FBI made the announcement.

The case was investigated by the DEA and FBI. The case is being prosecuted by Assistant United States Attorneys Nadia Ahmed, Edward Veronda, and Jean Ripley.
