*This post is purely conjecture regarding the psychology of and the type of person that could harm others in the way these poor kids were murdered if it was by a serial killer sub-type. I think it’s important to talk about and identify how/why this happens and the differences between motives behind these types of crimes which is what profilers do when looking for a perpetrator of violent crime.
As I write this I am assuming, for arguments sake, that this person was mostly unknown to the group and had no link to the Greek life because IMO, they did not know the layout of the house because if they did, I also believe there would have been 6 victims instead of 4. If this person was familiar at all with the victims, common sense tells me it would have been common knowledge to easily know how many roommates lived there and where to find them sleeping in their beds.
I do not think any one of the victims was specifically targeted per se because why risk trying to kill 4-6 other people when there was only one target?
And since we’ve broached the subject of contemplating what type of killing this was; i.e. Personal, Random, a mix of both, organized, disorganized, high IQ, low IQ, etc… Right now, with the evidence we have, I posit the theory he is (I will use the pronoun “he” because statistically speaking and by the sheer force and stamina it would take, “he” is most likely the correct description) a Thrill Killer, which is a serial killer subtype: Psychology research states they literally kill for the stalking, hunting, and the sheer act of it and are the least common type because there’s usually no rhyme or reason for their abhorrent and inhumane actions. They’re also (depending on how disorganized they are) more difficult to catch because of the randomness of their behavior.
Thrill killers are different from mass murderers (who aren’t considered a subtype), traditional serial killers, and “mission oriented” serial killers.
Here’s some interesting information I found regarding serial killer subtypes:
