I'm still stuck on why WH feels the need to tell us that he left the ignition key in the truck, but not the "door key" (which must be the front door key, since ignition keys open vehicle doors). So many strange things about that statement. If she is in the house when he drops off the truck, she obviously doesn't need a key. She's already in the house, yes? Would he leave her the house key so that she could get back into the house? C'mon...the kid lived in that house for several years, didn't she? Is he trying to suggest that she didn't have a key to the house? What about the other daughter who got home at 2:20ish from school? Didn't he have to leave a key for her? NO! She had a key to get into the house, just like AJ did (imo). So why tell us he didn't leave the door key in the mailbox? Was he supposed to turn in his key because he was booted from the residence? Is he trying to suggest that AJ MIGHT have left the door unlocked when they met at the gas station, and someone laid in wait for her inside the unlocked house? There is a reason WH makes this front door key an issue. Why? I can't put my finger on that to save my soul.
But one thing I think I have a handle on is why we have him telling us about the sighting of the white compact car. Because someone really DID see that car in the driveway.
