We can come up with theories till the cows come home but the truth always seems to be the most simple thing that comes to mind.
Gannon caused a little accident, TS got mad and flew off the handle, she ranted and she raved, she hit Gannon, she yelled, look what you have done, how many times have I told you not to play with fire, it got out of hand, her temper exploded, im sure their was trouble in her marriage even at that time and all her pent up rage came pouring out, Gannon got hurt, she knew he would tell, she possibly took his phone so he wouldn't, couldn't text his Dad or his Mom about what was going on, that's why he didn't have it.....
she realizes as she calms down what she just did, Gannon is hurt, cant take him to the doctor, cant let his Dad know, what can I do?
Ive got to get out of this somehow, and she did what a unstable person does when they know whats coming, she faked his disappearance, she did it and now she is stuck with it...….IMO..
I just hope he is found, I pray he is found,!!!!
