Street gang MS-13 was operating an underage prostitution ring where girls as young as 12 were working as prostitutes. Men would pay between $40 to $100 for 15 to 30 minuets of sex. The price for the sex was depending on how young the girl was, with sex with younger girls costing more. A gang member who acted as the pimp would carry a machete in order to ensure that the customer paid and was not violent with the girl.
A majority of the girls were runaways, with gang members recruiting them at school, parties or through mutual friends.
The MS-13 gang has between 1,500 to 3,000 members active in the Washington D.C. area.
