I'm one of those people that don't entirely believe the furniture store sighting of EB and Zahra. I firmly believe that a person (good with dates or not) would know what date a child in their care died. That is something that will stick in a person's mind. I also believe that there is no reason for EB to lie about the date that Zahra died. What would the purpose of that be? I can see about telling lies as to how the child died, who killed her, who dismembered her and who "dumped" her but not the date.
There is a connection between at least two of the women at the furniture store and someone that is not in all of this mess but is on the outskirts of it. I also find it extremely odd that for some unknown reasons the security camaras had not been turned on that day. Also, and I need some help remembering this part exactly, wasn't there conflicting stories from the 3 furniture store workers?! Like two said that EB and Zahra was there on the 25th and another one said that it was EB, Zahra and an unidentified woman?!
I don't believe more than half of what comes out of EBs mouth but I do tend to believe her on the date of death.
