Spring Valley Man Charged with Distributing Potent Synthetic Opioid that Resulted in Overdose Death of Pacific Beach Resident

SAN DIEGO - A federal grand jury returned an indictment today charging Matthew Ray Calas of Spring Valley with distributing a powerful synthetic opioid-N-Pyrrolidino Protonitazene-that resulted in the death of a 67-year-old San Diego resident.

According to court records, Calas advertised drugs for sale on Craigslist using coded language. In text messages with the victim, Calas offered to sell the victim "red devil nitazene," a smokeable crystal powder. The victim was found on the floor holding drug paraphernalia, suggesting he died shortly after ingesting the substance. Three months later, Calas sold more of the "Red Devil" to an undercover law enforcement officer.

Calas is also charged with Possession with Intent to Distribute Fentanyl, Butonitazene, and Methamphetamine; Possession of a Firearm in Furtherance of a Drug Trafficking Crime; and Felon in Possession of a Firearm and Ammunition.

N-Pyrrolidino Protonitazene (often abbreviated NPP) is a synthetic opioid in the nitazene family. Nitazenes are a class of laboratory-made opioids that were originally developed decades ago in pharmaceutical research but were generally not approved for medical use. Some newer nitazene analogs have emerged in the illicit drug supply and are associated with overdose deaths. It is extremely potent and has opioid effects similar to fentanyl and other powerful opioids. Naloxone (Narcan) can help reverse opioid overdose effects from NPP, though multiple doses may sometimes be needed with very potent opioids.

Special agents and officers with the Drug Enforcement Administration's Overdose Response Team led the investigation. This case is the result of ongoing efforts by the U.S. Attorney's Office, the San Diego County District Attorney's Office, the Drug Enforcement Administration, Homeland Security Investigations, the San Diego Police Department, the La Mesa Police Department, National Guard Counterdrug Task Force, the California Department of Health Care Services, and Naval Criminal Investigative Service to investigate and prosecute the distribution of dangerous illegal drugs-fentanyl in particular-that result in overdose deaths. The Drug Enforcement Administration created the Overdose Response Team as a response to the increase in overdose deaths in San Diego County.

This case is being prosecuted by Assistant U.S. Attorney Keith D. Ellison.
