Jimbo,its an urban legend spread from word of mouth and tsismis,they arent kidnapped for body-parts,I have heard the same thing when I was in central america,guy goes to party,given spiked drink,wakes up on waste ground with a crudely stitched wound where his kidney was,do a search on it,that legend has run all around the world,the easiest place to buy body-parts like kidneys is india,at least then your going to get a match in the hospital.
