Thanks for the info Rougelatete! It's heartbreaking to find out that some of the theories on here may prove to be reality, but this has gone on far too long. SM, M and all the others who loved Sky deserve answers.
I had previously read that JB left her apartment after the Facebook post early on Nov 4th (I think Robert A posted it somewhere) but as I couldn't trace it back to a source or any evidence, I discounted it.
If your source is right about Sky being killed on October 15/16, it certainly makes the timeline more interesting.
I believe the neighbour claimed to have seen Sky between Oct 15 and Oct 23 (I've read different accounts). If true, this person may have witnessed Sky's final hours.
Around Oct 25, JB proposed waiving support if she could take the kids to Scottsdale or Russia. As someone on here guessed, that may have been a desperate attempt to avoid having to produce both children and thus exposing Sky's absence.
On Oct 26, JB last accessed the sugar daddy site. Was she hoping to get some money to flee with M and leave all her problems behind?
Around Oct 27, JB borrows her brother's car for 10 days. I'm not sure what her intentions were at that time (could have been a way to disappear with M and avoid answering questions) but ultimately this car enabled her to stage the disappearance.
On Nov 1/2, JB attends the mediation and for nearly 12 hours, she digs in her heels and refuses to agree to anything. This tells me she had not come up with a plan yet. Eventually she is worn down and agrees.
On Nov 4, SM's attorneys are notified that JB felt pressured at the mediation and she is backing out of the agreement. Again, I think she was stalling for time because she didn't have a plan yet.
On Nov 5, that Law & Order SVU episode re-airs (originally aired on Oct 19). I think this is where she came up with her plan. As Clay Terry said in an article recently, JB isn't creative.
On Nov 6, Sky is reported missing, supposedly after being left in the car.
I'm not sure how JB leaving her apt early in the morning on Nov 4 factors in. I'm also not sure how those photos released by police factor in. When were the bank ones taken? Was JB planning on disappearing with M but when she couldn't come up with the necessary funds, she was forced to set up a scenario to explain Sky's absence?
Ugh, I'm so sick of trying to think like this woman. I too think LE needs to search the landfill asap. I imagine the longer they wait, the less likely a cause of death can be determined (though maybe we're beyond that point anyway). I cannot stand to see a repeat of the CA case!
