Danie Krugel
Danie Krugel is the inventor of the "Matter Orientation System" (MOS), a device which supposedly magically combines DNA and satellite tracking technology to track people across the globe. How this works has never been fully explained, although quantums have been mentioned several times. The MOS or "Bodyfinder" is a contender for James Randi's $1 million prize, but Krugel has so far refused to come forward and test his invention.
[edit] Madelein McCann
Krugel is most famous for putting his nose into the disappearance of Madeleine McCann in 2007 and reportedly produced a map and search pattern to find her. Naturally, to cover up the possibility of him being wrong, he released this statement: "I know that even if she was moved after July 2007, there will still be evidence of her presence in this area."
