1) We have witnessed staged disappearances before here in WS.
Elaine was noted as having depression issues, and everyone in her life stated some sort of mental state or change recently. I will assume these were all likely due to the multiple negative and disappointing things she had been going through lately.
Her car was likely not there from Saturday through Thursday, so someone dumped it. Either Elaine herself or whoever knows where she is.
2) Indeed there are a lot of questions about the video of her leaving that night. The mere fact that the entire, unedited video has not been released doesn't mean the homeowners are involved. Maybe LE is purposefully withholding some information. But, they absolutely should not do that with family members. The thing is, we don't know what the mother knows.
But, if that video was edited and they are refusing to hand over the full contents, then it is grounds to assume they are hiding something. If it was me and I had nothing to hide, I'd provide the video of every minute for the time she was seen walking out and up through today!
What's really going on here?
