(Shutterstock) (Newser) – Florida police say they have uncovered an online prostitution ring that was allegedly run by a 17-year-old girl. Alexa Nicole De Armas was arrested on Friday after police caught wind of the ring; four female students at Sarasota County's Venice High reportedly told their teachers that Alexa and a male student had pushed them to join the ring. Per police documents, Alexa and a second student came up with what the Herald-Tribune terms a "business plan" before the school year began. Their alleged intention was to pimp out fellow teens in exchange for money and alcohol. Deals were arranged via Facebook messages, and WWSB reports the girls said Alexa used Facebook to facilitate things because she doesn't have a cell phone. Students say three deals were made, and police say at least one sex act did take place: John Michael Mosher, 21, allegedly had sex with a 15-year-old against her will after forking over $40 and a bottle of liquor; he has been arrested. Police got a search warrant for Alexa's Facebook account, and say they found communications regarding participants, how to split the money, and pricing, which apparently topped out at $100. The Herald-Tribune prints one such exchange to a "business partner," which reads: "Why pimp out old hoes when I have fresh young hoes I can give up for money? As long as I'm getting paid I'm trafficking all these [expletive]." Alexa is charged with human trafficking of a person younger than 18. Police say a third person will be arrested today.
