Mexican National Charged After Killing of Attempted Carjacking Victim in Tucson, Arizona

TUCSON, Ariz. – Julio Cesar Aguirre, 42, of Mexico, was charged by criminal complaint on July 2, for Attempted Carjacking, Use and Discharge of a Firearm During and In Relation to a Crime of Violence, and Alien in Possession of a Firearm. Aguirre had his initial appearance in federal court in Tucson today.

According to the complaint, Aguirre shot and killed a male driver with a 9mm caliber handgun, while attempting to carjack the victim’s Toyota Tundra on the morning of June 30, in Tucson, Arizona.

Tucson Police Department (TPD) officers who were called to the scene spoke with witnesses before being directed to a nearby residence for a potential burglary. When they arrived at the home, the residents explained that a Hispanic male with a bleeding arm, matching Aguirre’s description, had entered their backyard and threatened them with a gun, demanding they turn over their vehicle to him. The individual later fled.

Shortly thereafter, TPD officers located Aguirre, who was hiding in a nearby storage shed. Officers also found a Smith & Wesson 9mm caliber pistol within Aguirre’s reach. Aguirre was taken into custody without further incident.

A search of Aguirre’s record revealed that he is a Mexican citizen, illegally present in the United States. Aguirre was arrested over 10 times from 2007 to 2013 for immigration-related crimes and was last removed from the country in 2013 pursuant to a court order.

The federal prosecution of this case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhoods (PSN).

TPD and the FBI Phoenix Division’s Tucson office are conducting the investigation in this case. The United States Attorney’s Office, District of Arizona, Tucson, is handling the prosecution on the federal charges. TPD and the Pima County Attorney’s Office will have an ongoing and parallel investigation into additional felony state charges, including homicide.

A criminal complaint is a formal accusation of criminal conduct. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
