Tenancingo: the town sex trafficking built
Tenancingo is a town built on sex trafficking, where families dupe young women from across Mexico into becoming sex slaves.
The women, often from Mexico's indigenous population, are wooed by men with grand homes.
Needing money for their families, the women discover too late they're being sold into prostitution - often in the US. One Mexican charity estimates there are 1,000 traffickers in Tenancingo out of a population of 10,000.
Sanctuary for Families, a New York group helping trafficking victims, saw a 150% increase in the number of cases between 2010 and 2011.
