Looks like FD was angling for a Frazee defense. No body, no crime. In fact, these Einsteins thought, "no body, NO INVESTIGATION." He planned it out. Get up early, drive a borrowed vehicle, ride his bike the last leg, overpower, remove, dispose, be back at 4JC while the sex shower was still running. His alibi script tells me that he fully expected the meeting with KM and the Greek phone call would cover for his absence, which means he expected being gone only a short time. MOO
Further, I think, if he did dispose of his beloved bicycle, he removed the labels to, in his pygmalion mind, render it identifiable. I think he thought no one would find ALL of his trash bags or connect them in any way, hence a little in this one, a little in that one. If no one were looking for JD, nobody'd get excited about some soiled paper towels and a bike logo, or so he must have reasoned. He's sunk. His DNA in the inside of a double pair of gloves and hers on the outside. Sunk.
And all for what? Money. To cover up his failures as a businessman, as a provider, as a husband, as a man. AS A HUMAN BEING.
Thank God for GF, stepping in, and protecting the children at all cost.
He's ruthless. Arguably soul-less.
LWOP for him and his co-conspirators. No one's safe if they're loose.
MOO MOO MOO
