Two men are in federal custody after authorities say they conspired to distribute tens of thousands of fentanyl pills and opened fire on federal agents during an attempted arrest in Phoenix this week.
According to the U.S. Attorney’s Office for the District of Arizona, Drug Enforcement Administration agents took Eduardo Valenzuela Lopez, a Mexican national, and Jael Gonzalez Banuelos of Phoenix into custody Tuesday following a confrontation tied to a suspected narcotics transaction.
Investigators allege the pair had been negotiating and organizing the sale of approximately 50,000 fentanyl pills throughout February. When agents moved in to inspect their vehicle near the location of the arranged deal, authorities say Valenzuela Lopez fired shots in their direction. No injuries were reported in the exchange.
The arrest was carried out by the Drug Enforcement Administration, which said agents recovered the suspected fentanyl pills from inside the vehicle’s passenger compartment. A firearm was also found on the driver’s side floorboard.
Federal prosecutors allege the quantity involved exceeds 400 grams of fentanyl — a threshold that carries significant penalties under federal law. If convicted, the two men face a mandatory minimum sentence of 10 years in prison, with the possibility of life behind bars. The charge also carries potential fines of up to $10 million and a supervised release term ranging from five years to life.
Valenzuela Lopez is described by authorities as being in the United States unlawfully.
Both men made their initial court appearances Wednesday, marking the beginning of what could become a high-stakes federal case amid ongoing efforts to combat fentanyl trafficking across Arizona and the Southwest.
