EL PASO, Texas — A U.S. Border Patrol agent, assigned to the Ysleta Border Patrol Station detained a Mexican National and convicted murderer attempting illegal entry into the United States Nov. 7.

The agent, while performing assigned line-watch duties south of the Padres Overpass, arrested Miguel Marines-Patino approximately two miles west of the Ysleta Port of Entry.

At the Ysleta Border Patrol Station, agents identified Marines-Patino, a.k.a. Pedro Rodriguez-Ruiz, and discovered his immigration and criminal history.

In July 1986, Marines-Patino was arrested for murder by police in Chicago, Ill., resulting in a conviction with a 24-year sentence. Marines-Patino was previously removed from the U.S. on two occasions, the last one being to Mexico on March 16, 2017, through Brownsville.

Federal authorities in El Paso filed a federal criminal complaint Friday morning, charging Marines-Patino with illegal re-entry after deportation. If convicted, Marines-Patino faces up to 20 years in federal prison. He remains in federal custody pending a detention hearing expected to occur next week in U.S. Magistrate Court in El Paso.
