She writes a letter to the Sheriff, no less, asking for help.
This seems to be the only time that Casey reaches out for anything or anyone and it just feels like this is important for some unknown reason. It's just a gut thing with me. After listening to GA's interview, at first I thought it was on the up and up, but listening to it again, I believe some things are not forthcoming and true to his best recollection. His past experience in LE makes me believe he was well prepared for the task in that interview. But this request from KC to the Sheriff has me scratching my head and I wonder does anyone feel the same. If KC and GA had the problems that have been reported in the interviews, why ask for him in particular? Some "THING", information, past/present that only the two of them could discuss because there is no doubt, secrets were being kept between LA & KC, CA & KC and now GA & KC....which also makes that statement by LP about "C, L and K all know the truth" stand out like a big clue...with no mention of G in the statement.
