HSTF Investigation Leads to 17 Years in Prison for Tucson's "Queen of the South," Bringing Her Reign to a Close
TUCSON, Ariz. – On Sep. 22, 2026, Senior United States District Judge Raner C. Collins sentenced Amanda Rachelle Miller, 35, of Tucson, to 204 months (17 years) in prison, followed by 36 months of supervised release, for leading a large-scale drug trafficking organization that distributed fentanyl, methamphetamine, and other dangerous drugs in Arizona. Miller was also ordered to pay a $25,000 fine, $25,000 in community restitution, and a $400 special assessment.
Miller directed the enterprise for more than three years while a fugitive in Culiacán, Sinaloa, Mexico, leading to three separate federal criminal indictments. As the self-described “Queen of the South,” she supervised couriers, orchestrated bulk drug deliveries, and managed cross‑border money laundering, in total involving dozens of co-conspirators. She also claimed to have conceived the idea for brightly colored “rainbow fentanyl” to boost slumping sales for the Sinaloa Cartel—a marketing tactic the DEA has identified as targeting children and young adults.
Several of Miller’s co-conspirators also received significant sentences.
Alberto Gabriel Aranda-Ramon, a Tucson-based principal leader who coordinated multi‑kilogram fentanyl and methamphetamine deliveries, supervised couriers, and laundered proceeds through straw purchases of luxury vehicles, was sentenced on Aug. 26, 2025, to 198 months (16.5 years) in prison, followed by 60 months of supervised release. Judge Collins also imposed a $25,000 fine, $25,000 in community restitution, and a $900 special assessment.
Michele Oller was sentenced to 120 months (10 years) in prison, followed by 60 months of supervised release, and was ordered to pay a $5,000 fine and $5,000 in community restitution on Feb. 4, 2025. Oller supervised regional distribution, coordinated deliveries, and collected commissions on multi‑kilogram drug transactions.
On Aug. 27, 2024, Rodrigo Lopez‑Lozoya was sentenced to 120 months (10 years) in prison, followed by 60 months of supervised release, and a $100 special assessment. Lopez-Lozoya transported 17 kilograms of methamphetamine from a Tucson stash house where agents later seized an additional 115 kilograms of methamphetamine, 16.5 kilograms of cocaine, two kilograms of heroin, and 12 firearms.
Yehoshua Kilp, identified as one of Miller’s bulk drug customers, was separately prosecuted in the Western District of Washington, where Chief U.S. District Judge David G. Estudillo sentenced him to 168 months (14 years) in prison for leading a drug cell tied to Aryan prison gangs in the Pacific Northwest. His sentence included accountability for laundering proceeds benefiting Miller. The Arizona charges were later dismissed.
During the multi‑year investigation, law enforcement seized substantial criminal proceeds from the organization, including approximately $134,444 in U.S. currency; luxury clothing, accessories, and jewelry valued at approximately $87,158; eight vehicles valued at $211,213 (including Forgiato Technica 22” rims worth $12,000); and fourteen firearms valued at over $9,000. Agents also seized Aranda-Ramon’s high‑end sneaker collection, which was forfeited to U.S. Customs and Border Protection and donated to the St. Vincent de Paul Society of Southern Arizona, where it was sold and 100% of the proceeds were used to assist families experiencing poverty in central Tucson.
In total, $58,000 in community restitution was ordered. Sixty‑five percent will be paid to the Arizona Criminal Justice Commission’s Crime Victim Services, which administers crime victim assistance statewide, and 35% will be paid to the Arizona Health Care Cost Containment System, designated to receive federal substance abuse block grant funds.
“These sentences reflect the strength of the partnership between federal, state, and local law enforcement in confronting one of the most prolific fentanyl trafficking networks operating in southern Arizona,” said United States Attorney Timothy Courchaine. “Miller, Aranda-Ramon, and Oller led a coordinated effort to flood our streets with extremely destructive narcotics, and their incarceration makes our community safer. We will continue to relentlessly pursue every organization that threatens the people of Arizona with fentanyl and other dangerous drugs.”
“DEA continues working diligently at targeting and dismantling these dangerous drug trafficking organizations who are poisoning Americans,” said, DEA Special Agent in Charge Apolonio “Polo” Ruiz. “Working with our law enforcement partners is paramount and necessary when standing united to build a Fentanyl Free America.”
“Leading a drug trafficking organization from outside the United States did not put Amanda Miller beyond the reach of law enforcement,” said U.S. Marshal Van Bayless for the District of Arizona. “This sentence reflects years of work by investigators and prosecutors across agencies to hold her accountable. The U.S. Marshals Service is proud to stand with our partners in protecting Arizona communities from the harm caused by fentanyl and other dangerous drugs.”
