Mara Salvatrucha, a widespread mostly Salvadoran gang seen by some as a rival in violence to the Mexican Mafia, is now believed to have ties to al-Qaeda.
“They’re out to make a name for themselves. They’re basically into anything,” says Sgt. Dionisio Cortez, a former Los Angeles-area cop who now serves as an educator for the south Texas gang task force. “They’re into smuggling humans. They’re into smuggling narcotics. They’re into killing people for any little reason. They’re very ruthless.”
