SAN ANTONIO – A Mexican national was arrested in San Antonio on criminal charges related to his alleged illegal possession of a firearm.

According to court documents, Sergio Lopez Rodriguez, 48, was arrested during a surveillance operation conducted by the Lone Star Fugitive Task Force (LSFTF) on Feb. 20. Federal law enforcement agencies had learned that Rodriguez was in the United States illegally and had previously been removed from the country in 2015. In addition to the deportation, Rodriguez was convicted of theft in 2009, of forgery in 2013, and also had been arrested and charged with unlawful possession of a firearm by a felon. A state arrest warrant was issued for Rodriguez on Jan. 28.

A filed criminal complaint alleges that, on Feb. 20, LSFTF members surrounded Rodriguez’s vehicle while he was parked a gas station pump. During the arrest, officers allegedly located a handgun, a magazine and .40 caliber ammunition, along with a glass pipe, torch lighter and .9 grams of a crystal-like substance. The complaint also alleges that Rodriguez informed officers that he possessed an AK-47 magazine inside a bag located in the vehicle.

Rodriguez was booked into the Bexar County Jail for his outstanding warrant and, due to his immigration status, Immigration and Customs Enforcement lodged a detainer. He is federally charged with one count of illegal alien in possession of a firearm. If convicted, he faces up to 15 years in federal prison and a $250,000 fine. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

Acting U.S. Attorney Margaret Leachman for the Western District of Texas made the announcement.

The U.S. Marshals Service, Immigration and Customs Enforcement, and the Bureau of Alcohol, Tobacco, Firearms and Explosives are investigating the case, along with the Office of the Texas Attorney General, Bexar County District Attorney’s Criminal Investigation Division and Bexar County Sheriff’s Office.

Assistant U.S. Attorney Fidel Esparza III is prosecuting the case on behalf of the United States.

A criminal complaint is merely an allegation and all defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
