A photo exhibit called "How Did I Get Here?" by Ada Trillo at a Philadelphia gallery is "bringing attention to sex trafficking" by Mexican pimps in the United States as reported by CBS News: "inside the 'Twenty Two Gallery' at 22nd and Latimer, two dozen black and white photos hang of Mexican sex workers."
Last April in a federal courthouse in Brooklyn, NY eight members of the Rendon-Reyes Trafficking Organization pleaded guilty to racketeering and other charges for their roles in forcing "young women from Mexico and Latin America to prostitute themselves in places like New York and Georgia" as reported by the Daily News.
More sex slaves exist in Mexico than any other country in the world according to the 2016 Global Slavery Index from Walk Free Index as reported by David Gagne for Insight Crime:
The report highlights how trafficking networks and other criminal groups profit from exploiting marginal populations, especially women and children. By some estimates, 70 percent of all modern slavery cases in Mexico involve organized crime groups. This includes the kidnapping of mostly girls and women for forced prostitution and mostly boys and men for forced labor.
The "drug cartels are believed to be involved in sex trafficking, the document says, using the same organized crime networks used to move drugs and weapons to smuggle human victims across the border into the United States."
