June 13, 2013 — -- Edward Snowden, a former contractor for the National Security Agency, slipped out of the U.S. in late May, traveling to Hong Kong with computers full of secret documents in order to expose what he called "horrifying" U.S. government surveillance capabilities.
He began in the shadows, leaking top secret files to The Guardian and The Washington Post, but just a few days after the first stories broke, Snowden stepped into the media spotlight himself, confessing to being the papers' source and telling viewers a little bit about himself.
Since then, little by little, the details of Snowden's life – the parts he left out -- have emerged, providing a picture of a smart kid who dropped out of high school only to embark on his own patchwork college education on his way to working for one of the most shadowy espionage agencies in the world. Here's what we know so far:
