You make a good point! I wonder if Ryan just doesn't remember?
DEFINITELY think this speaks to Bo's TRUE character (even further). Think they got the wrong dude--maybe he had something to do with helping Bo get rid of the body...but I don't think Ryan did it.
https://www.fox5atlanta.com/news/381458225-video Yeah, just saw this a bit late, but damn. This sheds light on his past motivations IMO.
I have always thought Bo took her to the house on Snapdragon and raped her for days before killing her. They (or he) burned the house down. I think Bo made Ryan the accessory and that is why Ryan kept quiet, or Bo convinced him he did it while Ryan was strung out.
