U.S. Attorney Ashley C. Hoff and FBI Special Agent in Charge Christopher Combs made the announcement today. A federal jury was presented evidence that Ferris visited a Temple pharmacy on multiple occasions in July and August of 2019, attempting to fill an out-of-state prescription for Fentanyl patches, according to the release. Ferris purposely identified himself as an FBI agent, that was on an out-of-town assignment, and used false documentation as well as a fake FBI identification card on a lanyard to get pharmacists to fulfill his request.
