So now the NEW timeline is based solely on his Facebook post ?? Seems awfully convenient.
I think that Facebook post was in a PAST tense. She was probably lying right there next to him when he sent it out. This would be an attempt at an alibi by a meth addict that had been up all night long stalking and waiting and watching for the right moment. However, when the right moment came, he screwed it all up because he underestimated her resistance level.
Only a drug-fueled mind, and someone who had been sipping beer all night long while waiting for his victim. could possibly see that Facebook post as a legitimate alibi. Anybody that has ever done meth knows that one of the side effects is the ability to stay awake for 24-48 hours without getting sleepy, and to drink larger quantities of alcohol without getting drunk. Both of those factors however have a huge impact on the brain and it's perception of reality. His facebook post that morning from a cellphone would fortify just how irrational he was becoming.
So where is Holly?? Well, after posting his weird alibi, he slung her over his shoulder, dragged her (who knows) to a waiting vehicle and made his escape. Somewhere along the way her lunch box got dropped and forgotten. It could have even been left right there where he made the Facebook post. Once out of the immediate search area. he had plenty of time to dispose of her. Tennessee has a lot of heavily forested area and very soft soil. She could be almost anywhere.
