Augustin Borja-Gaona, a 56-year-old Mexican national, was sentenced to 21 months in prison for unlawful reentry into the United States. The sentencing was announced by the United States Attorney’s Office for the Eastern District of Oklahoma.
Borja-Gaona, who has used multiple aliases including Augustine Borja and Genaro Borja-Reynoso, was found unlawfully present in Pittsburg County, Oklahoma. He pleaded guilty on August 18, 2025, to reentering the U.S. without permission after being previously removed in 1999, 2002, 2007, and 2012.
The case resulted from an investigation by the U.S. Department of Homeland Security’s Immigration and Customs Enforcement Division and the Pittsburg County Sheriff’s Office.
According to officials, “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.”
The sentencing hearing took place in Muskogee before Judge Robert J. Shelby of the United States District Court for the District of Utah, sitting by assignment. Borja-Gaona will remain in custody until he is transported to a federal prison facility to serve his sentence.
Assistant U.S. Attorney Erin Cornell represented the government at sentencing.
