Without any new info coming out, I just keep going over what we do know. Because of JB's OCD, I'm going to assume she's organized and probably a meticulous planner. I don't think her story was hatched overnight in a panic. I think every decision she made and action she took had a specific purpose and was well thought out in advance.
Working backwards:
Reports Sky missing. WHY? Because she knows he's gone and she needs an explanation.
Calls SO for help. WHY? SO lives about 14.5 miles/25 mins from gas stn (further than SJ or NB). JB wanted the extra time to create bigger window of opportunity for someone to snatch Sky. Maybe she thought SO would believe her story and be a good witness.
Walks to that specific gas station. WHY? Knows they are out of gas (apparently a common occurrence at that location) so she doesn't have to bother with gas can.
Leaves car unlocked. WHY? Makes abduction story more believable without need for broken windows or door locks.
Leaves "Sky" in car but takes M with her. WHY? Creates opportunity for snatching without leaving a witness.
Parks car along 112th Ave NE. WHY? She's familiar with area (used to live there?). Knows there are no cameras.
Car "runs out" of gas. WHY? Because she drove it until the fuel light came on.
Leaves her phone at home. WHY? So she can't call for help or be tracked via pings.
Goes out early Sunday morning. WHY? Fewer potential witnesses around? Her friends and family will be at church?
Emails friend saying Sky is sick. WHY? Wants someone to corroborate a part of her story.
Borrowed brother's car for 10 days. WHY? I'm not convinced she borrowed the car specifically because of Sky however, the car allowed her to set up the whole kidnap story. I wonder what the story would have been if she didn't have the car.
Questions I'd like answers to (other than the obvious one of where is Sky and what did JB do to him): Was Sky ever even in the Acura? Would dogs be able to tell if the scent was just in the car seat and blanket vs the car itself? What if she rubbed Sky's blanket on the backseat? Given her compulsive clothes washing, would she still have unwashed items of his, including blanket, days after he was gone? Can dogs pick up human scent on laundered items? Whose fingerprints were found on harness of car seat? Was M's car seat in the back or front seat of the car? An Integra is tight in the back and it wouldn't have taken much for M to reach over and touch "Sky". I wouldn't be surprised to learn M was actually sitting up front. Why didn't JB's brother see the kids when he dropped off the car? Did she give an excuse or deliberately set it up to avoid the possibility? What reason did she give police for calling SO that morning? If she had a sick child she was trying to get to a hospital, why not call a cab and deal with the car later?
*sigh* I know Sky will be found eventually but it's infuriating that she has the power to end this (and has for a month) but instead she's sitting in her brother's apartment playing on the internet.
