I looked back to the post you are referring to about the meeting on the 28th, and I don't read it the same as you. I thought it meant that Gail met with the PI on the 28th and picked up the info he had collected, not that he had seen Matt on the 28th in Chattanooga. I think the wording of the original post (timeline) was a little misleading.
Just my :twocents:
Personally, I am not as concerned as to what day MP was seen at the ATM and meeting up with this unidentified person in a coffee shop as I am to who this unidentified person may be and IF there were photos taken of this unidentified person by the PI Gail hired......IMO..And as I see it, IF Gail saw a picture of this unidentifed person that could very well be reason enough Gail hasn't been seen or heard of in over two months now....IYKWIM......JMHO
