Mexican National Sentenced to 37 Months in Prison for Illegal Reentry and Possession of Firearm

TUCSON, Ariz. - Jessica Guillen-Morales, 38, of Sonora, Mexico, was sentenced on August 12, by United States District Senior Judge Raner C. Collins to 37 months in prison, followed by 36 months of supervised release. Guillen-Morales previously pleaded guilty to Reentry of a Removed Alien and Alien in Possession of a Firearm.

On November 19, 2023, Tucson Police Department officers executed a search warrant at Guillen-Morales' residence and found approximately six firearms, including rifles, along with ammunition. Law enforcement officials determined that Guillen-Morales was previously convicted of the federal offense of Conspiracy to Transport Illegal Aliens in November 2012.

Law enforcement officials also learned that Guillen-Morales, a citizen and national of Mexico, had been previously removed from the United States on November 1, 2023, and did not have legal authority to be in the country.

This case is part of the National Public Safety Partnership (PSP), which was established by the U.S. Department of Justice to provide an innovative framework to enhance federal support of state, local, and tribal law enforcement and prosecution authorities in enhancing public safety. PSP began as a pilot program, the Violence Reduction Network, in 2014 and is designed to promote interagency coordination by leveraging specialized law enforcement expertise with dedicated prosecutorial resources to promote public and community safety. PSP serves as a DOJ-wide program that enables participating sites to consult with and receive expedited, coordinated training and technical assistance, and an array of resources from DOJ to enhance local public safety strategies. This model enables DOJ to provide jurisdictions of different sizes and diverse needs with data-driven, evidence-based strategies tailored to the unique local needs of participating cities to build their capacities to address violent crime challenges. PSP has engaged with more than 60 sites since the program's inception.

The Tucson Police Department and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) conducted the investigation in this case. Assistant U.S. Attorneys Julie A. Sottosanti and Adam Rossi, District of Arizona, Tucson, handled the prosecution.
