Tucson Man Gets 5 Years for Metal Rod Beating on Pascua Yaqui Land

A 38-year-old Tucson man has been sentenced to five years in federal prison for beating a man with a metal rod as he walked home near the Pascua Yaqui Reservation last December, leaving the victim with a broken arm. Sonny Reyes Lozano, an enrolled member of the Pascua Yaqui Tribe, struck the victim approximately eight times with the rod during the December 14, 2025 confrontation.

United States District Judge Rosemary Márquez handed down the 60-month sentence on August 19, followed by three years of supervised release, according to FBI Phoenix. The attack left the victim with a fractured ulna, and the case was formally resolved after Lozano pleaded guilty to a single felony count of Assault Resulting in Serious Bodily Injury, per the U.S. Department of Justice.

Already Under Federal Supervision When He Struck

At the time of the attack, Lozano was actively serving a term of federal supervised release stemming from a prior conviction, the Justice Department said. That detail proved significant at sentencing: prosecutors noted the December assault amounted to a violation of existing court oversight, an aggravating factor that fed into the ultimate five-year term out of a maximum allowable 10 years under 18 U.S.C. § 113(a)(6), the statute governing assault resulting in serious bodily injury.

Federal prosecutors filed the case in the U.S. District Court for the District of Arizona on December 23, 2025, under docket number 4:25-cr-05654, according to court records reviewed by PacerMonitor. The case was processed through the federal court's Tucson division. The criminal investigation itself was a joint effort between the FBI's Tucson office and the Pascua Yaqui Police Department, the same DOJ release notes.

Why the Case Landed in Federal Court

Because Lozano is an enrolled Native American and the assault occurred within Indian Country, jurisdiction fell to federal prosecutors rather than Arizona state courts. Under the federal Major Crimes Act, the federal government holds authority to prosecute major violent offenses — including felony assaults involving serious bodily injury — committed by enrolled Native Americans within tribal land, according to the Nebraska Law Review.

The Pascua Yaqui Reservation, known as New Pascua, sits roughly 10 to 15 miles southwest of downtown Tucson and covers between 773 and 1,200 acres, home to a resident tribal population of more than 3,000 members, per background compiled by Tribal Justice. Judge Márquez, who presided over the sentencing, has served on the federal bench in Tucson since her Senate confirmation in May 2014, after previously working as an Assistant Federal Public Defender and a Pima County public defender.

Part of a Broader Pattern in Tucson Federal Court

Lozano's sentencing landed on the same day as another major violent crime resolution tied to the same tribe. Enrolled Pascua Yaqui member Santiago Luis Valencia Jr. was sentenced in Tucson federal court to 87 months in prison for a fatal assault on the reservation, the Justice Department announced, a case Hoodline previously reported. Together, the two sentencings point to a continuing stream of federal prosecutions arising from violent incidents on Southern Arizona reservation land, a pattern also reflected in a separate federal indictment covered by Hoodline in 2024 involving a fatal altercation on the same reservation.
