"Before I go much further with posting details of the investigation, I would very much like to post a little more about Maura's life before the disappearance. If you knew Maura, please contact me at becarriedaway@hotmail.com"

I found the supervisor interview very interesting. It looks like Maura was upset about something her sister said. Perhaps, she hurt Maura's feelings without knowing it? I'm trying to see it through a siblings point of view. I have 4 siblings too, like Maura. Every once in a while, over the years feelings can get hurt over a small thing said or misunderstanding. I may be way off base, but it appears Maura may have been upset over something her sister said or Maura was misunderstanding her sister in some way over their conversation. Perhaps, Maura was just super sensitive that day and took something wrong.
Hope this makes sense!
