Tucson’s ‘Queen of the South,’ Who Claimed She Dreamed Up Rainbow Fentanyl for the Sinaloa Cartel, Gets 17 Years
Amanda Rachelle Miller, a 35-year-old Tucson woman who called herself the “Queen of the South,” was sentenced to 17 years in federal prison for running an Arizona drug trafficking organization for more than three years while a fugitive in Culiacán, Sinaloa, the U.S. Attorney’s Office for the District of Arizona said in a Sept. 25, 2026, release. She also claimed to have come up with brightly colored “rainbow fentanyl” to boost slumping sales for the Sinaloa Cartel, prosecutors said.
The sentence
Senior U.S. District Judge Raner C. Collins sentenced Miller on Sept. 22 to 204 months in prison and 36 months of supervised release. He also ordered a $25,000 fine and $25,000 in community restitution, according to the release. Prosecutors said her organization distributed fentanyl, methamphetamine and other drugs in Arizona. They said she supervised couriers, arranged bulk deliveries and managed cross-border money laundering involving dozens of co-conspirators. The DEA has described the rainbow-pill tactic as aimed at children and young adults, the release said.
From a Tucson motel to Culiacán
According to a July 2024 release from the same office, agents first arrested Miller on Nov. 12, 2020, as she ran from a downtown Tucson motel. The motel was the target of a drug investigation, and agents found drugs, more than $25,000 in cash and two ledgers there. After being placed on pre-trial release, she fled to Mexico. In 2021 an undercover officer posing as a bulk buyer contacted her over social media. Prosecutors alleged she told him she was “direct from [the] [S]inaloa [C]artel.” She was caught in Culiacán and deported to the United States on May 30, 2024.

Her co-defendants
Alberto Gabriel Aranda-Ramon, described as a Tucson-based principal leader who laundered money through straw purchases of luxury vehicles, received 16.5 years. Michele Oller got 10 years. Courier Rodrigo Lopez-Lozoya also got 10 years. He moved 17 kilograms of meth from a Tucson stash house, where agents later seized 115 more kilograms of meth, 16.5 kilograms of cocaine and 12 firearms. In Washington state, bulk customer Yehoshua Kilp got 14 years for leading a drug cell that prosecutors tied to Aryan prison gangs.
Agents seized about $134,444 in cash, eight vehicles and 14 firearms. They also seized Aranda-Ramon’s sneaker collection, which was donated to charity, the release said. U.S. Attorney Timothy Courchaine called it “one of the most prolific fentanyl trafficking networks operating in southern Arizona.”
