Thank you elmo! ITA We shouldn't split hairs over what was said when, why, and by whom. Oftentimes we don't have the context and are in danger of misinterpreting statements. I think the bigger picture is more important than single sentences picked up here and there.
The only reason to analyse things IM said would be to sleuth her and we don't sleuth family members.
I don't think it matters when she found the wallet, or whether she knew or just deducted later by looking at his things in the bathroom whether he shaved that morning or not.
If she said she saw him last in the early morning or the previous evening we should believe her and not endlessly wonder whether she was home at 2:50 pm. I don't think it's fair to go down that path. I don't think she was home, I think she would have said so if 2:50 was the last time she saw him.
NCNY has cleared up a lot of misunderstandings, thank you for that!
Focussing on Rob - he went to work, he visited a scrap yard afterwards, came home, put some cash and possibly the wallet in the garage (purposely? absentmindedly?), possibly put his bike into his car, and drove off, vanishing without a trace. At about the same time he took off from his home his phone went dead. (How weird!) His car was found the next day at the very spot in the parking lot at Deer Park Station where he used to park years ago whenever he took the train. Bike is missing along with Rob.
What does that tell us? What was he likely up to? I asked this before, want to ask it again: are there any scenic biking trails in this area which you would reach by train? Was there maybe some kind of mountain bike enthusiasts event that Friday afternoon?
