A man will serve 3.5 years in an Arizona prison on multiple charges related to fentanyl trafficking.

Tomas Gamez-Robles was sentenced in Pima County Superior Court on Dec. 30 after pleading guilty to charges of attempt to transport a narcotic drug for sale, possession of a deadly weapon during the commission of a drug felony and illegally conducting an enterprise.

Gamez-Robles was arrested on March 5, 2024, in Pima County after attempting to transport 1.429 pounds of fentanyl pills for sale. At the time of his arrest, he was in possession of a firearm and approximately 0.128 pounds of methamphetamine, which he also intended to sell, according to a press release from the Arizona Attorney General’s Office.

Investigators determined Gamez-Robles was trafficking fentanyl pills, methamphetamine, and heroin to generate money, according to the release.

“Individuals who transport deadly drugs into our communities will be held accountable,” said Attorney General Kris Mayes in the press release. “My office will continue to use every tool at our disposal to combat the spread of dangerous drugs and protect Arizonans.”

Gamez-Robles was sentenced to 3.5 years in prison transporting narcotics, 3.5 years in prison for illegally conducting an enterprise, and 2.5 years in prison for the weapons charge. All sentences will run concurrently. Additionally, Gamez-Robles also was ordered to pay $4,500 to the state Anti-Racketeering Revolving Fund and to forfeit the firearm involved in the case.

The Arizona Department of Public Safety conducted the investigation, and Assistant Attorney General Sabrina Lochner prosecuted the case.
