Sorry, I keep throwing random bits in here as they come to me...
I just wanted to add that this whole situation feels pretty calculated to me, so wherever he is, it was a pre-planned spot. I’m thinking the hikes may have been a way for her to check out certain locations and plan without seeming suspicious. I wonder if hiking was something they did often? It’s kind of chilly and the kids seem kind of young to just head out on a hike... but that’s just me. I also think in sudden accidents where people panic (say an unexpected injury), it is much harder for them to “act normal” and play things off. If they have played the scenario out in their heads for some time, they’re mentally ready. The backwards interview was weird & doesn’t quite fit for me, but being kicked out of the house was probably unexpected and led to some deviation from the “plan.”
I am also curious about the prescription that was apparently called in for the stomach issue? That would have been Monday morning, yes? Was it filled? Perhaps that’s where they drove off to? I’m also wondering about potential side effects of whatever it was... drowsiness?
