Just jumping off your post in reference to RL's trip to the refuse transfer center:
Actually, believe it or not, I think this piece of information is helpful to RL. We know the transfer center closes at 4:00pm and the Abby's pic of BG was @2:30.
In theory, That gives RL less than 1.5 hours to "walk/force" the girls to his property, do god only knows what, murder them, (maybe also clean them off in the river and clean himself off in the river *complete speculation on my part), collect whatever evidence from the scene, go back to his house to more than likely clean up better (with soap at least since he will be seen in public), put said evidence in garbage bags, then get in his truck to get to the transfer station before it closes at 4:00pm.
That's a lot, IMO. Also, and most importantly: Landfills have specific protocols of how they dispose of refuse so garbage can be found by knowing when it came in. IMO, taking evidence himself (where people keep records and give receipts) to a transfer center on the day the girls were murdered would be the most idiotic thing RL or anyone could do if they didn't want to get caught.
This part of Indiana is not urban. It would make so much more sense if a person who just committed a gruesome murder to not go personally to the dump and drop their trash there after they just got done killing two girls. It would make more sense for that said person to burn it, bury it, throw it into a river 50 miles away, throw it in a random dumpster, etc... But not take it immediately to a transfer center where the evidence could be tracked and traced specifically back to him. Honestly. :facepalm:
