Exactly! This is pretty evident from the FB exchange the other day, as well...
I also find it odd that only Amber and her mom seem to be willing to go on SM to clear up inconsistencies, provide info, answer questions - anything, to help the investigation. I haven't heard much from Katelin's immediate family. Although I have no right to judge how a family responds to something of this nature, I do hope that KA's family speaks out soon to help provide additional details that might help bring their loved one home.
It would be nice to know if she met with any friends while on her visit home, what her mood was, how she felt about returning to AZ, if she was excited or scared to start school, why the family friend couldn't drive her to the airport, if it was normal to shop at Springfield Mall or if her computer history shows her looking up the stores there or researching how to catch the metro from the mall itself. Was it commonplace to take the metro to the airport? Was she a seasoned traveler; would she know how to navigate metro and airport check-in by herself? Did she do online check-in from home, showing she had every intention of catching the plane? Had anyone heard from her at all once she was dropped off at the SD's house? (If she was a frequent texter, she probably was contacting someone in between the time her mom dropped her off there and the time she made it to the mall?). Just any of these questions would help provide a little more info… jmo
