A federal grand jury unsealed a 15-count indictment on Nov. 9 charging five Salt Lake County residents for their alleged roles in an organized criminal enterprise. The indictment includes charges related to the distribution of fentanyl, methamphetamine, and cocaine, with prosecutors alleging one sale of fentanyl resulted in a person's death.
