In January, the National Enquirer published leaked text messages between Amazon CEO Jeff Bezos and former TV anchor Lauren Sanchez, as part of its investigation of their alleged affair.
Now, Bezos has tasked his personal chief of security, Gavin de Becker, with tracking down the party (or parties) responsible for the leak, reports the Daily Beast. In particular, he's said to be investigating the possibility that Michael Sanchez, Lauren's brother, was involved.
The 64-year-old de Becker is an established security expert, who founded a private security firm used by federal agencies to protect government officials and public figures. He's also something of a celebrity in his own right: De Becker consulted in the criminal prosecution of OJ Simpson, wrote a New York Times-bestselling book, assisted President Ronald Reagan with security, and made two appearances on "Oprah" to discuss his work.
