Moo, My personal theory came down to the recent LE interviews (a few days ago) with Snell from State of Idaho Police, and Moscow PD Chief.
Interview with State of Idaho Police Officer Snell
Moscow, Idaho, Police Chief James Fry told NewsNation he believes the initial hours of the high-profile investigation were handled properly.

Interview with Moscow PD Police Chief Fry
Investigators continue to look into several leads, including a 2011-2013 white Hyundai Elantra that could have been at the scene the night of the murders.

A few notable things was the focus of their investigations are largely digital evidence gathering and getting the full context (moo, motive, events leading up to the killing) Although they’re still on the subject of tracing the vehicle whereabouts (evidence of its location preceding to the murder) this was not discuss in the interview. They are specifically asking “possible witnesses”who may have seen something unusual a day or two before the murder, they further reiterate their need for additional (social media) pictures and videos. For obvious reason, LE were not asking the general public for help, they’re asking those who “knew”. (Victims inner circle, friends and acquaintances or sm followers)
Moo, What happened in those two days leading up to the murder? They’re college students, more likely they partied together or separately on Friday night then on Saturday night E and X were at a frat party and K&M were at the bar. Moo, They were with people they’re acquainted with (as per video evidence with K&M and E and X reports their presence in the frat party gathering). They were surrounded by people they knew.
Moo, the most likely scenario for me is a different group within their inner circle, could be in a frat/sorority were in some sort of dispute with E and X or all four of them (hence 2 roommates were spared). An individual or two may have harbor hatred, envy or both imo, this was probably talked about among this other group (group of 2 to 4 people) and likely started off as a simple venting conversation. They are most likely another student/s who may have fantasized about something like this before and probably have an idea on how they wanted to kill people. Perhaps there was an inciting incident that caused them to react with violence. Moo, this conclusions were due to the fact that LE seems to suggest that there were people who knew about what happened as per their press release “
Investigators believe someone has information that adds context to what occurred on the night of the murders and continue requesting additional pictures, video, and social media content.”
Moo, I’ve seen some people believe that the killer may have been a pro, however one does not need to be a pro to evade police for a few months and sometimes for years or forever. There are various cases were a killer successfully elude investigators due to not having enough evidence but it did catch up sooner or later.
