Three MS-13 gang leaders from El Salvador face life in prison after being convicted of murder, racketeering and weapons offenses in New Jersey, authorities said.

Juan Pablo Escalante-Melgar, 31; Elmer Cruz-Diaz, 33 and Oscar Sanchez-Aguilar, 25, were also involved in extortion, drug trafficking and witness tampering between September 2014 and October 2015, the U.S. Attorney’s Office for New Jersey said in a statement Tuesday.

Escalante-Melgar and Sanchez-Aguilar told a member and a recruit to kill a suspected rival gang member so that the recruit could become a full member of MS-13, officials said.
