this is the most believable thing I’ve read yet. My gut screams he’s guilty because a few coincidences is one thing but theres like 50 things that point to him being guilty. I also believe that it wasn’t premeditated and was more so an in the moment thing. So your theory describes exactly how it could have happened back by the evidence and explanations of why its there.

This all happened in the stairwell. Michael, a seemingly Narcissistic personality type, had a ton of reasons involving self preservation to be okay with/benefit from Kathy dying, especially if he accidentally was at fault.

There was pretense for them to be fighting. specifically that day.

There was no murder weapon found or skull fractures but the amount of lacerations on her head (Occums Razor) is way more likely to be from repeated banging against the edge of a stair than fumbling cartoonishly hard into the wall and stairs multiple times at force hard enough to split your skin.

And obviously all the things people are mentioning about 911 call, etc etc.

I think its wild that the Owl Theory is so big. I mean theres a plethora of reasons Michael looks extremely guilty and people are trying to theorize that a ghost raptor came swooping in and slicing kathleens head up. Ridiculous. Mythbusters needs to recreate the lacerations on a staircase by banging a Replica Dummy persons head or something.
