Many victims are immigrants who are taken advantage of by traffickers-usually don't speak English and won't go to the police for fear of being deported

Aging populations poor diets, & limited health insurance systems=increased organ disease.
Poor people are often approached and promised a large sum of money if they will let doctors take a "hunk of meat" from their bodies. The traffickers then take the kidney and sell it on the black market. In this particular case,the victim received less then 1% of the amount agreed upon.
