In the United States, the Gulf Cartel has been responsible for several kidnappings, primarily in the McAllen metropolitan area. Investigators believe that more unreported kidnappings have occurred in nearby locations. When victims are kidnapped by the drug cartels on American territory, kidnappers usually hide them in the trunk of a car and take them to Mexico. FBI investigators said that victims are "kidnapped, threatened, assaulted, drugged and transported into Mexico to meet with Cartel members." Reports indicated that kidnappers working for the Gulf Cartel train with paintball equipment "to practice simulated kidnapping schemes in order to prepare for the actual kidnapping they intended to commit." In one reported incident, Isaac Sanchez Gutierrez, a man from Palmview, Texas, said he faced an ultimatum: pay $10 million to the Gulf Cartel, or transport 50 drug loads from Mexico into the U.S. in order to free his kidnapped brother.
