Amazon CEO Jeff Bezos is the world’s richest man. He also enjoys his privacy. Bezos has publicly accused The National Enquirer of trying blackmail him by threatening to release intimate photos of him. Unless he calls off an investigation into how that information was obtained in the first place, that is. Private investigators working for Jeff Bezos have determined who leaked the intimate text messages. SFGate reports the investigators have concluded that it was the brother of Bezos's mistress.
