I know a lot of this has been mentioned, but for my own sake I'm going to state my opinion lol
1. I have a very bad feeling about the neighbor....although I never like people who refuse to take a poly---shows they're hiding something IMO
2. She left her car somewhere else. I've personally done that before and have gotten an itch to go get it, I've walked very far, I've gotten rides from neighbors/friends, etc very, VERY early in the morning. I think this would be the ONLY viable excuse to leave (since they've checked her phone for booty calls, etc)
3. It IS possible for a guy and girl to have a platonic relationship. I am an only child and have many guy friends who my b/f would trust me with, even to stay the night.
4. I would def. want to talk to everyone at that bar, as a partier, there is always an after-party and most of the time the skeezy, weirdo who was at the bar all night alone will attempt to tag-along---so will older men. Could be possible acquaintances from earlier in the night were attempting to meet up and when KS and her friend were found sleeping, the perp snuck her out.
5. I really, really don't trust the neighbor most of all. Had to put that out there again.
Had to get all that off my chest, thanks

Let's bring KS home!
