It doesn't have to be something unusual or extraordinary to be interesting. Personally I found it pretty interesting simply to see how the wheels of justice turn, just like I used to watch detective shows when I was a kid.

One odd little thing that caught my eye: the way they used archive.org to establish some history of the victim's Wikipedia page. I would have expected that they would have used Wikipedia's own edit history for that. It made me wonder if the FBI agent just didn't know about the Wikipedia edit history, or if they thought archive.org was a more reliable source.
