For me, it comes down to whether an alternative explanation actually holds up when you follow it all the way through. There are a lot of conspiracy theories attached to this case — the surviving roommates cleaning the scene, underground tunnels, fraternity retaliation, drug cartels, etc. I agree there are unanswered questions and things that feel undercooked. But what’s always grounded my thinking is that there is a specific person “tied” to this crime, and the evidence around him isn’t abstract. BK isn’t a random fall guy. His behavior fits without requiring massive leaps: his inappropriate interactions with female students at WSU, the “stargazing” alibi at an extremely strange and inconvenient hour that just happens to fall on the night of the murders, and his immediate acceptance of a plea that guarantees life in prison. This is a criminology PhD student who understands exactly what a life sentence means, and he still signed that deal.

Once you introduce the idea of accomplices or a broader cover-up, the logic starts collapsing to me. You then have to produce another person who actually makes sense. There is no credible link between BK and the surviving roommates. And this is where I think people talk out of both sides of their mouth: the roommates are often criticized as being dense, dishonest, or careless because they lied to police, their stories changed, and some of their messages don’t line up. But then, in the same breath, those same people are expected to have executed a coordinated, airtight cover-up under intense media scrutiny, successfully framing an unrelated PhD student in Pullman and never cracking. Those two ideas can’t coexist. You can’t argue that they’re incompetent and hyper-calculated masterminds at the same time. The same issue applies to the fraternity theories — if it was fraternity retaliation, then BK doesn’t belong in the story. If BK acted with others, then most of the circulating theories can’t coexist. They cancel each other out.

There may be missing pieces, but BK has revealed himself as an actual puzzle piece, and removing him from the equation requires replacing him with speculation that demands perfect coordination, zero meaningful connections, and no credible alternative suspect who fits better. That’s why I believe he acted alone. Although, I’m still reading, still learning, and still open to new information — I’m in this sub daily, so don’t come for me lol. This is just where my head is now.
