Hey, took a break to make and eat dinner and I missed the new development. So, here's what I think about the Waste Management visit. IF PF did it, he sent those text messages to buy time...and it worked. It was over 10 days before anyone suspected anything right? You buy time to get a headstart and cover your tracks. So, in that time he could have taken half a dozen trips to the dump and no one would have thought anything of it. If there was evidence for him to dispose of, I'm confident he already did it.
Why did he go today? Well, he clearly isn't consumed with searching for Kelsey, so he's probably going about his business as usual. I think the trip was probably in the normal course of his business. And why did he bring help and stay in the truck? Well, it's 100% obvious he wants nothing to do with the media and everyone is watching his every move, so he asked some friends to help so he didn't get recognized and hounded by media.
Those are my thoughts.....
