MS-13 member Heriberto Martinez was sentenced to life for the cold-blooded execution-style murders of a 19-year-old woman and her 2-year-old son over the mother's apparent disrespect of the street gang in Long Island, NY as reported by William Murphy for Newsday.
MS-13 is among the more degenerate gangs.
It originated in Los Angeles, CA but now operates in at least five countries with more than 30,000 members. In the United States MS has so-called cliques in 40 states and about 8,000 members. Its money making rackets principally include drug trafficking and the flesh trade. In Northern Virginia 12 MS-13 gang members "have been locked up for child sex trafficking in the past two years" as reported by Pamela Brown for WJLA:
"We're seeing most of the cases coming from MS-13 with regards to sex trafficking and we've seen a number of those cases from the past year," said John Torres, Special Agent in Charge with ICE Homeland Security Investigations. "For us it's a disturbing trend."
In October 2012 the Treasury Department designated MS-13 as a transnational criminal organization under Executive Order 13581 which freezes their U.S. assets and bans Americans from conducting business with them, and in a follow-up move added six of the gang's purported leaders to the economic blacklist as reported by Jerry Seper for The Washington Times.
