Dylan claims he hung out with Michael all the time yet when he asked him about the reference...it appears they were not together for those two weeks.
In 2000, the company was a start up ISP and Michael's desk was a cardboard box according to Dylan. The photo shows something entirely different with the caption: Photo of Michael de Bourcier c2000
I find it strange the police (and subsequently the PI) don't know where this person is buried if it only takes a phone call. The funeral service company may not tell Dylan (which again is odd because it is not a problem in the US for anyone to be given that info), but LE should have easy access.
I am finding a few discrepancies in Dylan's account of things. This sounds more like a made for TV movie or a series than an actual false identity case.
