I think a lot of assumptions were made and became accepted as fact that we now know are not true. Most of these will be resolved as more evidence becomes public. However, not all. Most cases have an unresolved question or two that is not critical to conviction and won't ever be resolved unless the perpetrator decides to provide the information. For example, LE probably doesn't have the knife and likely won't need it for a conviction. Its whereabouts won't be known unless Bryan Kohberger tells them where to find it.
Kudos to the MPD (and other LE agencies involved) for staying focused on the objective: catching the perpetrator and making sure he can be prosecuted. Satisfying the curiosity of the amateur sleuths around the country is not part of their job. Despite being heavily criticized by some, it is clear that LE was right on track in this investigation.
And don't forget the pissing cat that triggered the ring video that caught the Elantra!
Bryan Slow-burger didn't count on the Viking Kittehs!
