Did I miss it? (The article is dense.) I'm not seeing how the authorities identified him. I see lots of identifying information from disparate sources, which when taken collectively does seem damning. But not how it all got put together, nor any discussion of why now.

I mean the guy offered his own $10m bounty if you could track him down.

I knew back when the Boeing data got out, that it was a fatal mistake and he'd be hunted down. It obviously wasn't easy since the $10m would have been enough incentive for the army of internet super sleuths. I don't care at all about what the bits and pieces are, what I want to know is the HOW. as per the title
