Mexican National Sentenced to 24 Months in Prison for Firearms Offense

HARRISBURG - The United States Attorney's Office for the Middle District of Pennsylvania announced that Diego Edgardo Aleman-Lozano, age 25, a Mexican national, was sentenced on October 2, 2025, to 24 months in prison to be followed by one year on supervised release by United States District Judge Jennifer P. Wilson for possession of a firearm by an alien.

According to United States Attorney Brian D. Miller, Aleman-Lozano was pulled over by Pennsylvania State Police in 2021 for violations of the Pennsylvania Motor Vehicle Code. State Troopers saw a 5.56 caliber green-tipped rifle cartridge on the front passenger seat. Because Aleman-Lozano was an alien on a nonimmigrant visa and was therefore not permitted to possess a firearm or ammunition, law enforcement obtained a search warrant for the car. Upon executing the warrant, Troopers recovered a 9mm polymer semiautomatic pistol with no serial number.

This case is part of Operation Take Back America (https://www.justice.gov/dag/media/1393746/dl?inline) 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 Neighborhood (PSN).

This matter was investigated by the United States Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Assistant United States Attorney Michael Scalera prosecuted the case.

This matter occurred on date indicated but not issued at that time due to the government shutdown. Press release posted and made available following the return to normal operations.
