Mexican National Sentenced to More Than 17 Years in Federal Prison for Smuggling Liquid Meth into U.S. in Propane Tanks

DEL RIO, Texas - A Mexican national was sentenced in a federal court in Del Rio to 210 months in prison for importing 163 kgs of liquid methamphetamine from Mexico into the United States, announced U.S. Attorney Justin R. Simmons for the Western District of Texas.

According to court documents, on June 5, 2022, Paul Ivan Palmero-Martinez, 51, pulled up to the Eagle Pass Port of Entry driving a Ford F350 tow truck. He stated that he was traveling from Piedras Negras to San Antonio to purchase motor bikes for his business in Mexico, and that he had nothing to declare.

U.S. Customs and Border Protection officers (CBPO) directed Palmero-Martinez to secondary inspection, where he stated he was traveling to San Antonio to purchase an engine. A CBPO opened the back compartment of Palmero-Martinez's vehicle and located two large propane tanks that looked and smelled as if they were recently painted. A K9 alerted to the smell of narcotics. Further inspection revealed anomalies in the propane tanks, which were then cut open to reveal six large packages of methamphetamine with a total weight of 168.2 kgs.

Palmero-Martinez told ICE Homeland Security Investigations agents that a co-conspirator was supposed to pay him for transporting the methamphetamine to San Antonio. He further admitted that he had previously transported the F350 from Mexico to San Antonio through the Del Rio Port of Entry to establish a crossing history and that he received $800 from the co-conspirator for doing so.

Following his arrest, Palmero-Martinez was charged in a four-count indictment. He pleaded guilty to one count on Sept. 19, 2022. Chief U.S. District Judge Alia Moses presided over the case.

ICE HSI investigated the case.

Assistant U.S. Attorney Brett Miner prosecuted the case.

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.
