Spitballing.....
I'd like to see some scenarios where JMC is NOT involved and is just a well....ya know...not nice person...
I thought of this in the very early days of the case when discussing what door JOK entered the house through. What if JOK never did enter the house and instead, was called around to the back yard? What if a couple of the guys were out there smoking say and maybe letting Chloe out? What if they saw JOK walking up to the house and said "Hey! We're back here!" and he went to the back yard where all that stuff happened.
That might explain whey no one saw him IN the house and those who testified that JOK was never INSIDE the house, aren't "lying." Maybe it was simply BA, BH, JOK and poooossssibly CA in the back yard at the time with Chloe and they would be the only ones who knew what happened. Maybe Jen knew, I don't know, but it would certainly explain how so many people are saying they didn't see him in the house because they never did see him, in the house or otherwise.
Blinds are drawn, music is playing inside, lots of people chatting and wouldn't hear what might have been going on outside. These things can't happen in the blink of eye, a fight AND a dog attack. You always here that said when a dog attacks - it all happened so fast!
I do believe that many of these people honestly believe KR is guilty, such as the O'K family, BAs wife, the other partygoers, etc... albeit maybe not seeing clearly. I don't believe it takes an entire village of conspiracy to cover up a murder, as all it really needs is 2-3 people who can use their authority to push a narrative, and others to perhaps "help it along the way" to solidify the case.
