I think this is a really great thread. A lot can be learned in hindsight by rereading these LE interviews.
Casey did have the opportunity to retrieve her "work ID."
Casey changed her story and told Lee the odor started around Cindy's b-day!
Wow! I wonder what else we might find. This is all very interesting! Good sleuthing!
I'm going to relisten to a few of his interviews and try and record several instances where he appears to laugh inappropriately. I think it could show a pattern.
Although, there are probably a ton and it could just be the way he acts.
