Police found an Elantra on video, and put out a bulletin to other law enforcement agencies in the area to see what they could find in regards to that vehicle, during the timeframe in question. WSU police did just that, and came up with Bryan Kohberger. So the car led police to him.
Later on, thanks to IGG, DNA led them to the same man. That's what I mean by two independent lines of inquiry, coming up with BK.
That idea that investigators couldn't pin down the year of the car is absolutely meaningless when you put those two things together. It proves that they were initially wrong about the year, not that it wasn't his car.
His phone had no business being in the area on those 12 of so occasions prior. If it was the daytime, that's one thing. The late night/early morning trips show that this was a scouting mission, just what you'd expect from a guy who wanted to commit the perfect crime. He would have wanted to not only get a lay of the land, but get a lay of the land during the time in which he'd be committing the crime.
This WIFI thing is new to me, but his phone magically going out of service during the precise time in question, a time that fits perfectly with his car's movements and the phone data they do have, is ridiculous on its face. No one is going to believe that's a coincidence, not with the rest of it.
Again, I believe slam dunk. By the time we hear the rest of it, it'll be a solo slam dunk contest.
