It's true we haven't known his identity until recently, but as a true crime community, we've been discussing the killer's likely intelligence or lack therof for a month and a half.
When the police (rightly IMO) withheld all evidence except about the Elantra, we hypothesized that it was a very clever person who could kill four individuals in two rooms without leaving evidence behind.
Now we know who the culprit is, and we hear from his colleagues and professors that he was so, so brilliant, although he was a difficult character.
That leaves many of us speculating that if he is a criminologist, a PhD. candidate, what mistake did he make that led to him?
Eventually we find out that his Master's thesis seems very substandard, incomplete, done online, and done too late in the semester.
IMO it is worth a discussion, because if he were ACTUALLY brilliant, this may have become a perfect crime. I'm elated he's not as brilliant as claimed, or this would be a cold case for future generations of LE to pull out of a cardboard box in Idaho.
