LOL - Haleigh's relatives' arrival times are a big fascination on this Forum ! :crazy:
I agree that LE most probably does know all these call times and hopefully we will know them for certain one day as well. Until then, they are a piece of the puzzle and an important one, IMO. And while we can not pin them down with certainty, we can try to determine the feasability of calls made within a particular time frame. This can be tedious and I appreciate your willingness to dig down into the data, Whisperer.
As to the arrival times, LE may be able to rely upon cell phone ping records, with the caveat that the ping is the phone, not the owner. IMO, all arrival times at that mh from the moment Haleigh stepped off the bus until the scene until the first patrol car arrived are extremely important. And arrival times that occured shortly after the arrival of LE, may lead to clues as to the whereabouts that evening of the arrivees.
