I can't think of a reason, either. Unless I consider that she may not have been telling the truth.
And like I said yesterday (I think)--in my heart of hearts I don't believe that.
During my searches for something else, I did come across the link where it is mention Jenn was possibly in bed:
Jenn's boyfriend--Snipped Quote: Nothing out of the ordinary. I`ve known Jennifer for about the last 12 months, and we talked periodically throughout the day every day, every night before she goes to bed, every morning before, when she wakes up. We`d recently just come back from a vacation, and we talked throughout the day on Monday, and then Monday evening, she called me `round about 10:00 o`clock. She was in bed. She was tired from the vacation that we had just recently taken, had a long day at work. We talked briefly. No problem at all. We both said we missed each other and we were looking forward to the next time we were going to spend with each other.

A couple of comments on this, Truth. He says they talked briefly and I expect that is the most accurate statement we would get on it. There is probably a long distance record that has exact duration on it but that is close enough. I expect briefly to be about 5 minutes or less. This says they had already talked that evening. This was essentially a good night call. Whether immediately followed by yawning and going to sleep alleged ping data has something to say about that.
Secondly, this is from an original interview. This is where I saw (and I believe I have it filed away somewhere) his statement "every morning before, when she wakes up".
I expected that meant earlier than going to work, and that lack of a call from her and lack of answering the phone indicated she wasn't there. To me this was very significant. In addition to no postive indications of her being there that morning, you have this very substantial information that she wasn't there to place or take a call they had every morning.
But it got sidelined into a she called him on in car on way to work, and of course she didn't make it to work. I tried hard to get a confirmation that no calls normally took place earlier and that it was unexpected for Jennifer not to place a call earlier, or whether Rob tried earlier and no answer.
If that's the facts, then so be it, although I was hoping for harder clarification than the next to nothing that's been said, and it would have to be said by her bf.
"every morning before, when she wakes up" doesn't sound like when she starts driving to work a couple of hours after waking up. But if it is, and there was zero anticipation of getting or placing a call prior to driving to work, then I'll consider his statement clarified.
Until then, it's a big question and indicates to me she wasn't there early to participate as their usual routine.
