Although it’s hard to totally put KAK’s involvement to rest on this case after everything we kept hearing about him, I agree with what you are saying.
I think things we considered suspicious at the time, was not KAK trying to cover up his involvement in the girls’ murders but him trying to cover up his CSAM operation, since he knew A/shots had been talking with Libby.
His commenting as A/shots to another young teen, that he was supposed to meet up with Libby was just him playing his A/shots role. He was probably thinking by playing the comforting guy, he could manipulate these children even more.
KAK also is a liar levels above our comprehension. LE finally nailed him on the CSAM charges and were suspicious of his connection to the murders. They interrogated him hard. KAK realized he could walk a line of lies with LE because they were so desperate. He could play them for preferential treatment, and since he has no conscious, doing this on the back of two dead children didn’t matter at all to him. He played that game until someone finally ratted out RA.
I think Libby was handled more brutally during the murders simply because she was the least cooperative of the victims.
It took awhile for me to come around to it, but I believe these two beautiful girls were murdered by a tiny disgusting man for no other reason than to fulfill his sick selfish fantasies. No one else helped him.
My opinion, of which there have been many.
My opinion, until further notice.
