I couldn't quote some things because it was closed in the previous thread.
Yes, Randy and Brandon both have alibis.
The blood stained shirt thing was super bizarre, and it felt on par with being "super clever and cute" wearing the full SWAT getup for its many different purposes (concealing identity, keeping forensics off, adding a layer of protection, generally throwing chaos and speculation into the case) and that most normal people would just trash a bloody shirt, especially if their DIL was just viciously murdered and people were looking at them very closely.
I want SO badly to say that Randy and Brandon were not involved. The shirt irks me though. It feels like another "clever/cute" attempt to see how closely the police where watching them all, mixed in with taunting and/or adding a red herring.
I personally think that this was more than likely a female in the SWAT gear. I have 3 specific women in mind with three very different motives behind it.
Two of the women have some really strong things that point to them, with specific details that would really make you go "hmmmmmmmmm".
The third one, I will just flat out say it. Brandon's sister acts SUPER defensive and weird any time an interview is given. She goes WAY out her way to defend Brandon and Randy, really aggressively and like she is about to attack. I realize this is simply some people's personalities, but it just feels so off.
So, if a mix of the other two women make you go "hmmm" and Randy, his wife, and Brandon are conveniently out of town, then who could suit up and take Missy out? She could have carried out the plan in the SWAT suit, which also could have made other people look like they were the ones in the suit.
I am not saying she did it, and my gut tells me that Randy and his crew weren't involved, but something is not quite right somewhere.
