So, to play off what you are saying and what KariKae wrote in the post above yours, when Det. Gates said in the press conference on Friday, June 19th that ""Terri is the last known person to have seen Kyron alive before he disappeared," (
http://www.cbsnews.com/8301-504083_162-20008192-504083.html?tag=contentMain;contentBody), that LE don't necessarily think that Kyron ever made it school that Friday morning? Do LE have perhaps have confirmation (perhaps from Kaine that he saw Terri and Kyron leave that morning from their home) that Kyron was with Terri that morning but they don't think that Terri *and* Kyron both made it to school that morning? Which means that, in terms of their investigation, Terri would indeed be the last know person to have seen Kyron alive that morning (it just would not have been at 8:45 at Skyline, like has been reported).
Perhaps they only have confirmation on Terri, who spoke with the PTA President (who later changed her story to say that she only saw Terri?) and with Kyron's teacher? And they don't have anyone else saying that they actually saw Kyron that morning. What about the classmate who said he spoke with Kyron that morning?
And then there is the issue of Kyron's clothing. The LE has put out that Kyron was wearing a CSI shirt and cargo pants when he went missing. That is the outfit that he has on in the photo of him taken in front of his science project, which is what has also made people believe it was taken on the same day/Friday. If that picture was not taken on Friday morning, and perhaps taken the day before, was he wearing the same outfit two days in a row?
