It seems to me that there is a strategy in this latest focus on SM that is not necessarily one of suspicion. Otherwise, LE would have had to eliminate entire segments of the timeline (according to various articles) to continue to state that she is the last to have seen him:
8:45 SM waves goodbye to Kyron as she departs school hall and he is at or almost at his homeroom.
9:00 Unidentified school sighting of Kyron reported initially by LE, but mysteriously dropped:
Homerooms separate into groups of approximately 6 students each. Parent/volunteer chaperone sets out with her group, including Kyron, to tour sci-fair projects in other rooms?
or
Kyron passes his classmate in hall while loosely walking around with his group and mentions he's going to view the cool e-sci-project?
10:00 Student groups return to homerooms. Parent/volunteer chaperone of Kyron's group notices he didn't return with the group
(she had to have seen Kyron when the group formed to recall him; also only 5 students returning in the group wouldn't have stood out to her if she hadn't started out with 6).
Why can't the public know if LE has confirmed that the group chaperone did take note of Kyron not returning to the class with the group. Why would the classmate make this up? This is essential to determining if this is an abduction or not.
