There are a number of interested non-runners from work who are following this thread. A longtime lurker co-worker of mine wrote a good summary for those new to the story...current as of Thursday night. It's missing all of the analysis of sweat patterns, but I'm not sure that adds much.
Quick summary:
Philly area guy, late 40s, local media personality (radio?) -- very active in blogging, tweeting, facebooking (i.e. bigtime attention whore). Gets into running about 2 years ago, turns out to be decent for a bigger guy (~7 min miles for 5k, ~8 min miles for longer races). Profusely blogs every training run and race, complete with GPS splits, selfies, etc. Buys Boston marathon gear many months in advance of 2015 race and wears it everywhere.
Takes his kids out of school for a couple of days so they can come cheer him on at the Boston marathon this year. REALLY hams it up on social media (including patriotism, etc.), Gets "scolded" somehow for taking the kids out of school, or maybe it was no more than having their absence being listed as "unauthorized" (whatever that might mean).
Decides to get ultra-sanctimonious, calls out the principal on social media for being so square, blogs about how his kids learned more about life -- hard work (qualifying for and then finishing the Boston marathon), patriotism, history (as a tourist), etc. -- than they would in a year of school. (all this in spite of the rules about authorized absence being clearly understood by all, and clearly broken here) And look -- even more attention for our man!
Another local runner decides to look up his Boston qualifying race (Lehigh Valley marathon, 2014 I think), sees a 3:11 (3:25 was required for age 45-49), realizes this is about 10 standard deviations faster than any other race he's ever run (i.e. a billion to one chance of being legit).
Letsrunners join in and go through every one of the ~18k pictures from the race, for the ~1050 runners. The only runner in the entire field (they checked the entire >1000 runners, by bib number and also in the lost and found photo section) who was not photographed anywhere on the course except the finish line was our guy. Among the 50 finishers immediately before and the 50 finishers immediately after our guy, there are an average of >12 photos per runner. But for our guy, just the finish line photo. The race was chip timed, but being a smaller event, only had mats at start and finish lines.
More sleuthing on social media history. Our guy brags incessantly about every race he's done (and lots of training runs too), EXCEPT this incredible breakthrough performance of a lifetime that got him his Boston qualifier. And bragged incessantly about how he was going to be running Boston, well before even posting a qualifying time (or anything remotely close to that level of performance in any race distance). Recall the Boston gear mentioned above...
The walls are closing in, he takes all his social media feeds to private status, and issues a few lame rebuttals. Claims to have GPS watch record of the LV marathon but won't release it. They trace a handful of sockpuppet posters on letsrun (defending the cheater) to have all come from the same IP address in Camp Hill, PA. Close to where our man lives...
Local Philly media outlets (who had previously broadcast the story on him calling out the school principal) are now picking up the story of how he cheated, and describing the damning photographic evidence (i.e. summarizing the letsrun thread).
