Thanks for your explanation! Since HN cut of your URLs, the similarity between the filenames didn't jump to my eye. You're right, 2007 doesn't mention Puncher, it only mentions his close colleague Birchall. Both were publishing articles together around the time [1-4], so I find it hard to believe that he wouldn't work on such a high-profile case that was being solved by their computer software [2]. Since Buzzfeed authors talked to Birchall and Puncher’s family, I trust their accounts of his involvement.
