The Arizona Attorney General's Office has delivered a tough sentence to a father and son duo for their roles in the fentanyl trade. Augustin Nava-Nunez will serve a decade in prison, while his son Agustin Nava Jr. is facing two years behind bars with an extra two years of supervised probation. According to the Arizona Attorney General's Office, Nava-Nunez pleaded guilty to a charge involving the sale of narcotics, specifically fentanyl, and had a prior felony conviction.
Nava-Nunez's son met a slightly more lenient fate, sentenced for his part in the illegal enterprise, after both were caught in a long-term investigation that kicked off in mid-2024. "My office has been directed to aggressively investigate and prosecute those who are part of the network of fentanyl dealers infiltrating our communities," stated Attorney General Mayes. The observation of multiple drug transactions, by law enforcement, revealed the father-son dynamic at play – with Nava Jr. handling the exchanges at his father's direction.
The investigation, which began on July 15, 2024, utilized surveillance techniques to track the two individuals around Phoenix, documenting their illicit activities. On October 21, 2024, authorities discovered that Nava-Nunez was in possession of significant quantities of fentanyl. They seized approximately 7,500 pills weighing .777 grams from a trashcan in the backyard of the residence he shared with his son.
Justice was served on June 18, 2025, when Nava-Nunez received his 10-year sentence to be served at the Arizona Department of Corrections. Nava Jr., saw the inside of a courtroom slightly earlier, on May 20, 2025, when he was sentenced to a two-year stint in corrections, followed by, supervised probation. The AG's Office Criminal Division led the prosecution, delivering yet another blow to the narcotics distribution networks operating within Arizona.
For those interested in the details of the case, the Attorney General's Office has provided the indictment online. Furthermore, images of Nava-Nunez at the time of his booking can be accessed for visual record. These resources offer a closer look at the consequences faced by those who choose to engage in the sale and distribution of dangerous narcotics such as fentanyl, a persistent challenge in communities statewide.
