Arizona Correctional Officer Accused of Smuggling Ammunition for Sinaloa Cartel Faction

San Luis Río Colorado, Sonora — Mexican security forces arrested a 22-year-old Arizona correctional officer accused of acting as a logistics operator for a Sinaloa Cartel faction, seizing more than 5,400 rounds of ammunition from her vehicle, authorities said.

The suspect, identified by Mexican officials as Yanet “N” and in Mexican press reports as Yanet Dowden, was stopped during a surveillance operation near a bridge linking Sonora to Arizona. Mexico’s Security Cabinet said the cartridges were hidden under the seat of her Jeep Wrangler.

Investigators also recovered several firearms, including an AK-47, according to the Mexican newspaper Excelsior, which reported that she was carrying an Arizona Department of Corrections, Rehabilitation & Reentry identification card listing her as a “Level II correctional officer.” She turned 22 on Saturday, according to one of her social media accounts.

Excelsior reported that she is linked to Los Mayos, one of two factions inside the Sinaloa Cartel. Los Mayos is commanded by Ismael “Mayito Flaco” Zambada Zicairos, son of Ismael “El Mayo” Zambada, who co-founded the cartel with Joaquín “El Chapo” Guzmán. The rival faction, Los Chapitos, is run by Guzmán’s two sons, Iván Archivaldo Guzmán Salazar and Jesús Alfredo Guzmán Salazar.

Mexico’s Security Cabinet said the seizure dealt a blow to the cartel’s operations. “These actions impair the operational capacity of criminal groups and prevent weapons and ammunition from being used to incite violence,” the cabinet said in a statement.

The arrest underscores Mexico’s long-standing complaint that large quantities of weapons and ammunition are smuggled into the country from the United States. Mexico has strict gun laws and only one store where civilians can legally purchase firearms.

The Mexican government filed a $10 billion lawsuit against U.S. gun manufacturers in 2021, arguing that at least 70% of the firearms trafficked into Mexico originated in the United States. Officials accused the companies of knowingly selling to traffickers who bought guns for the sole purpose of smuggling them across the border.

The U.S. Supreme Court blocked the suit from proceeding in June 2025, ruling that federal law shields gun companies from liability when their firearms are used to commit crimes. In her opinion, Justice Elena Kagan wrote that Mexico’s case failed to identify specific criminal transactions that the defendants allegedly assisted.

“It does not pinpoint, as most aiding-and-abetting claims do, any specific criminal transactions that the defendants (allegedly) assisted,” Kagan wrote.

The Post sought comment from Mexico’s Attorney General’s Office and the Arizona Department of Corrections, Rehabilitation & Reentry.
