Arizona’s ‘Queen of the South’ drug trafficker sentenced to 17 years in prison

The woman known as the “Queen of the South” was sentenced to 17 years in prison for her role in a drug trafficking ring.

Amanda Miller, 35, will have three years of probation that follow her prison sentence for leading a large-scale drug trafficking organization that distributed fentanyl, methamphetamine and other dangerous drugs in Arizona. The sentence followed three separate federal criminal indictments.

Miller managed the drug enterprise for three years while a fugitive in Culiacán, Sinaloa, Mexico. She supervised couriers, orchestrated bulk drug deliveries and managed cross-border money laundering, involving dozens of co-conspirators.

“Leading a drug trafficking organization from outside the United States did not put Amanda Miller beyond the reach of law enforcement,” U.S. Marshal Van Bayless said in a press release. “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.”

According to authorities, Miller claimed to be responsible for coming up with the idea of brightly colored “rainbow fentanyl” pills, a marketing tactic that targeted children and young adults to boost sales for the Sinaloa cartel.

Several of Miller’s co-conspirators have also been sentenced:

• Alberto Gabriel Aranda-Ramon: 16 1/2 years in prison, followed by five years of supervised release (Aug. 26, 2025)
• Michele Oller: 10 years in prison, followed by five years of supervised release (Feb. 4, 2025)
• Rodrigo Lopez-Lozoya: 10 years in prison, followed by five years of supervised release (Aug. 27, 2024)
• Yehoshua Kilp: 14 years in prison (prosecuted in Washington state)

Additionally, $441,815 in proceeds was seized by the DEA, and the defendants were ordered to pay a total of $58,000 in community restitution.

“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,” U.S. Attorney Timothy Courchaine said. “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.”
