Ok......how about he snuck in one of the entrances during the party? Poked around and if seen, everyone just assumed he was a guest?
I'm reaching....I know!
Everyone in that house knew everyone else. Everyone was known to the Ramseys or to their closest friends. There were no strangers there.
No need to bother, bonfire...Rte66 has every base covered. Already said that everyone there was known by the others. The prosecutor needs Rte66 and it will all be over...like yesterday.
Seriously, I'm not naysaying what has been presented here, but I can't accept there's nothing there against Karr for the murder until I get it from a shall-we-say more official source, after every "i" is dotted and "t" crossed.
Hopefully it will be done that carefully.
