Another angle that doesn't add up to me is financial.
So in a video TS herself posted/leaked, she's demonstrating the excellent parenting approach (please note my sarcasm) of threatening/guilting her 11 yo stepson about how they're going to have to sell a sofa or figure out some other way to come up with cash so they don't get kicked out of their home because of what he's done (candle/carpet incident). What a wonderful stepmother to be so caring toward your stepson after an accident that he's clearly distressed about.... And crazy enough to think this video will make you look better or help you defend yourself in any way... I digress.
Then - in TS's own timeline of the day her stepson went missing, she's talking about buying non-necessity items like a bike and hockey equipment to give herself an alibi. Makes no sense. If you're so hard up that you can't afford to repair a damaged carpet without selling your furniture, why are you out buying a bike and hockey equipment? Additionally, if your finances are tight, I believe most programs for youth hockey provide equipment to those in need.
The whole thing is just so, so off. Poor Gannon.
Never stood a chance with this narcissistic sociopath as his stepmom. She had everyone fooled, but I hope it's her own tripping over her own lies that are her undoing in the end. I also hope she trips up enough to at least tell Al and Landen where Gannon is.
