yeah...when I first posted the article, I wanted to see if anyone else thought he was a little insincere (almost fake?) in the video before I stated my opinion. Now I know it's not just me.
However, he could also just be camera-shy.
As far as Luke not calling in their disappearance until 7:15pm when Mike and him talk all the time, I don't think it is too suspicious.
I'm almost 100% certain that before the disappearance Mike had occasionally left his phone at home or didn't charge it the night before so it was dead. I'm thinking Luke thought this was one of those situations. Maybe, Tina and Luke weren't on good terms(which I understand is sometimes common for older stepchildren) or he knew she would be busy with work so he didn't bother texting her. My sister and I text a few times during the day and occasionally she or I will forget to charge our phones and we won't hear a reply back until later in the evening when either of us gets back home from work.
One thing I think is interesting is that where the car was found at(Ralson and Papago) wasn't the usual way to get to Tina's work. If I was driving from their home, I would turn left when exiting their family compound. However, where the car was found, you would have to turn right when leaving their house. I don't have a theory. Just thought it was interesting.
Also, I keep reading that her purse was at home. Was it just the purse or was her wallet in there too?
