MS 13 Y MS 18 TODOS UN SOLO CORAZON

Many Mara Salvatrucha members cover themselves in tattoos. Common markings include "MS", "Salvatrucha", the "Devil Horns", the name of their clique, and other symbols.^[37] A December 2007 CNN internet news article stated that the gang was moving away from the tattoos in an attempt to commit crimes without being noticed.^[38]
Members of Mara Salvatrucha, like members of most modern American gangs, utilize a system of hand signs for purposes of identification and communication. One of the most commonly displayed is the "devil's head" which forms an 'M' when displayed upside down. This hand sign is similar to the same symbol commonly seen displayed by heavy metal musicians and their fans. Founders of Mara Salvatrucha borrowed the hand sign after attending concerts of heavy metal bands.
