Norcalnative, I agree. Although we ALL have our own ways of reacting and wording.
I can't see ANYONE replying the simple "No, it's going to be a late day," 3 hours later. Even if he happen to have a 2:00p.m. lunch. Wouldn't a logical text back be, " I'm sorry I missed you text," (Even though she knows he cant bring his phone in) or perhaps, "Obviously I couldn't make it babe." It doesn't even make sense. And when things don't make sense it raises A LOT of suspicion.
What if she didn't even text, "Are you coming home?" Ex. Pre-planned. Buying anyone time. (I'm not accusing the husband.) Even if it was her deciding to act out of character, in orded to successfully throw people off, so it wouldn't appear she left on her own. 90 percent of the time when things don't add up and make logical sense there's a reason why..and behind those questions of why. Are always lies. In this case I see major lies.
It's quite obvious we don't know much, or close to the whole story..and I believe there's a reason behind why.
I've followed thousands of missing person cases, runaways, suicides in my line of work. Studied psychology/sociology for multiple years.
But still it's...
Just my opinion.
