Newbie here so be kind. I've noticed on my AT&T bill that an "odd" number will show up to indicate a text message was sent or received from a source other than another cell phone. For example, if I instant message my daughter at college and she has her im's set to go to her phone as a text message (versus her computer), then the bill will show an "odd" number. By odd I mean not a typical phone number (less than 10 digits). So, KC could have been texting (or receiving text) from someone on the computer via AIM or MSN Messenger....etc.
Also, is it possible KC was calling herself while she was at home to make it look (OR SOUND) like she was receiving phone calls on her cell. Busy, busy girl you know with work and all...............I know this is what it looks like on June 16th around 8am when it looks like her home phone calls her cell phone. If GA and CA are telling the truth and she was at home that morning.........what else could it have been?
