MS-13 doesn't fear prison, President Trump or even death. But there is one thing that scares the hell out of tattooed members of the murderous Central American gang: La Sombra Negra. Spanish for "The Black Shadow," La Sombra Negra is a mysterious paramilitary organization that is part death squad, part vigilante group, and dedicated to responding in extreme kind to MS-13's ruthlessness. MS-13 members captured by La Somba Negra purportedly have been sexually tortured and dismembered before being dispatched with a bullet, their bodies left to be discovered by family or fellow gang members.
