No inside source. But I have three reasons to believe that she did not drive that Hummer there nor did she send that text.
1. Up until 3:15 pm she had been in constant contact with friends and family. All of that stopped at that time. There was that ONE , one word text, in reply to her brother. But it did not ping in the area that her Hummer was found.
2.But besides that, she did not follow up with her 11 yr old sone who was home alone. The sister said that the 11 yr old was given a cell phone so that he could call Michelle EVERY DAY as he left the school bus to walk home alone.
That call to his mom was always between 3:30 and 3:45pm. She either answered him or called back on every occasion. But NOT on this day.
So, imo, she did not just drive away from Dales and go shopping or go on a work call, because she would have checked in with her son first. And she did not do so that afternoon.
3. Also, Dale told LE that Michelle drove away 10 minutes later. If that were true I believe that LE would have seen her on the exit camera, driving away with the decals on the Hummer. And I think that Dale would be off the list as the top suspect in that case. Since he is still their prime susopect, I don't think the cameras have corroborated his version of the events that afternoon/
