The members of my family who are from/still live in Mexico (Sinaloa) have told me that if I ever visit I should be weary of people seeking to take me and sell me off into the sex trade.
I was told a story about a family of tourists. They went out to have dinner at a restaurant. There was a table of men who wouldn't stop eyeing them, particularly the beautiful, blonde daughter.
One of the men supposedly walked up to the father and told him "Your dinner for you and your family has been paid for. Enjoy it. This is the last one you'll have with her", as he looked over at her.
The family didn't finish their dinner, they just got up, and left. As they were driving away, Dad realized they needed gas, so he had to pull over at the next stop. Once he did, another vehicle drove up, 4 men jumped out, armed and visibly so, and took the daughter away. By the time anyone could do/say anything they were gone. No one sent for ransom, no one heard from her or her abductors again.
I have no idea if that's just an urban legend, but I damn sure fuckin' hope it is.
