Naaaa....RF got her out of his house the night this happened. All the noise and stomping around that the neighbors heard was a by-product of him trying to clean up the crime scene and get her loaded into his vehicle. These neighbors of his were trying to sleep, but he kept waking them up with all of the noise he was making. If they had looked out of their window at just the right moment, I'm sure they would have seen him loading something wrapped in a blanket or a sheet into his vehicle.........something pretty heavy and cumbersome. His neighbors simply weren't looking outside, or in the right direction, at the right moment.
I think he took her off and dumped her that night......"somewhere". Only after he got back into town did he meet up with CE and start to formulate a plan on what should be done next. That's when they gathered up all the digging supplies, borrowed the pickup, got the painters drop cloths, and headed out to do a more thorough job of hiding the crime. Somewhere along the way, CE must have had something in his vehicle that made him gravely concerned about trace evidence and touch evidence, thus his annoying insistence that his buddy detail his car in the days afterwards.
There's always the possibility that she was never moved again. The two of them showed up together in order to try and hide the crime. Where she was found may have been the original dumping spot that RF chose. Then again, it may not have been. They may have picked her up in one place and transported her many miles away to a more secluded area. CE knows all the answers. Whether he decides to offer it up or not is left to be seen.
