I thought about the length of time we're talking here, the large cash withdrawal(s)afterwards...No one was counting on the call to the roommate factor IF it was premeditated, or if not premeditated at least hoping she had not spoken with anyone between pay phone call and PTL to let them know she had been in contact with SM. Maybe if it wasn't planned, things unfolded, hence the large cash withdrawal with an initial knee-jerk reaction intent to leave the area, but hesitancy KNOWING, even if they thought they covered their tracks THAT night, sooner rather than later LE WOULD come knocking simply due to the past relationship; they needed to be around at least for the first knock, right? And maybe they thought, stupidly so, one knock and Tammy & Sid's 'charm' was all it would take to send LE along their merry way. But oh, how wrong they were.....So maybe, and I'm eluding to things gently here, they had to put disposal 'on ice' for a while, just a couple weeks to get their heads together and not look like they were GTHOD, but meanwhile 'hey, there IS still the problem in the freezer we need to deal with, Sid.'
I wonder if all storage facilities where someone could store a chest freezer w/ electricity were checked, and again, gently as I may, all power tools accounted for and thoroughly analyzed, etc. Reason tells me they would not have kept any devices used on her though.
