Attorney General Mayes Announces Sentence for Fentanyl and Methamphetamine Dealer, Sentencing Pending for Co-Defendant

TUCSON — Attorney General Kris Mayes today announced that Andronico Arvizu III was sentenced to five years in prison in Pima County Superior Court on February 3, 2026, following his guilty plea to Attempt to Transport for Sale or Sell a Narcotic Drug, a class 3 felony; Misconduct Involving Weapons by a Prohibited Possessor, a class 4 felony; and Illegally Conducting an Enterprise, a class 3 felony.

“Trafficking fentanyl and methamphetamine puts lives at risk and tears families and communities apart,” said Attorney General Kris Mayes. “Those who choose to profit from addiction and violence will be held accountable, and my office will continue working with our law enforcement partners to dismantle these criminal networks.”

Between June 16 and September 17, 2025, Arvizu knowingly participated in a drug-trafficking enterprise in Pima County alongside his co-defendant and significant other, Priscilla Cassandra Fimbres. Arvizu assisted Fimbres in selling fentanyl pills and jointly possessed approximately 12 pounds of methamphetamine intended for sale.

On June 18, 2025, Arvizu drove Fimbres to a planned drug transaction involving approximately 2.1 pounds of fentanyl pills. On September 17, 2025, Arvizu was found in possession of a Ruger LCP 9mm handgun despite being legally prohibited from possessing a firearm due to his criminal history.

The court sentenced Arvizu to five years in prison for Attempt to Transport for Sale or Sell a Narcotic Drug, to be served concurrently with five years for Illegally Conducting an Enterprise. He received 139 days of presentence incarceration credit. Upon release, Arvizu will serve two years of probation for the weapons offense. The court also ordered the forfeiture of the firearm and payment of $4,500 to the State Anti-Racketeering Revolving Fund.

Fimbres pled guilty to Misconduct Involving Weapons by a Prohibited Possessor, Attempt to Possess a Dangerous Drug for Sale, and Illegally Conducting an Enterprise. She faces a sentencing range of 3.5 to 8.75 years in prison, followed by up to four years of probation. Her sentencing is scheduled for February 10, 2026.

The Arizona Department of Public Safety investigated the case and it was prosecuted by Assistant Attorney General Sabrina Lochner.
