LAREDO—At the same time that Mexican cartels appear to be gearing up for war, Homeland Security officials are making a public plea for information on suspicious cross-border activity.
“Obviously, arms going to Mexico is a big part of that—that building up between the cartels,” said Timothy Tubbs, acting special agent in charge of Homeland Security investigations (HSI) in San Antonio. HSI is the investigative arm of Immigration and Customs Enforcement (ICE) and is responsible for investigating transnational crime and threats.
