Illegal Alien Sentenced For Unlawful Entry And Document Fraud

MUSKOGEE, OKLAHOMA - The United States Attorney's Office for the Eastern District of Oklahoma announced that Roberto Lopez-Mendez, a/k/a Roberto Lopez Mendez, a/k/a Roberto Lopez, age 27, a Mexican national unlawfully present in Haskell County, Oklahoma, was sentenced to six months in prison for one count of Document Fraud, and six months in prison for one count of Illegal Entry - Misdemeanor. The Court ordered the sentences to be served concurrently.

The charges arose from an investigation by the U.S. Department of Homeland Security's Immigration and Customs Enforcement Division and the Stigler Police Department.

On July 28, 2025, Lopez-Mendez pleaded guilty to the charges in federal district court. According to investigators, on June 9, 2025, Lopez-Mendez, who was illegally present in the United States, knowingly possessed a United States of America Permanent Residency Card, which he knew to be forged, counterfeited, altered, falsely made, or which was otherwise unlawfully obtained.

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 Honorable Raúl M. Arias-Marxuach, Chief Judge in the United States District Court for the District of Puerto Rico, sitting by assignment, presided over the hearing. Lopez-Mendez will remain in the custody of the U.S. Marshals Service pending transportation to a designated United States Bureau of Prisons facility to serve a non-paroleable sentence of incarceration.

Assistant U.S. Attorney Erin Cornell represented the United States.
