I read everything I could about this case when it was hot. My gut says: It was someone at the party, one of last hangers-on. Everyone's passed out or left or outside havin' a smoke, she was leaving to go meet the cab, "Hey I can give you a ride down the block to the cab." and that's it. She got in his car, it was almost 5am on a Sunday, the US 60 is right there, take that east to Idaho Rd... She got in a car with someone who she didn't really know. After the crazy night she had her judgment would have been off. Couple blocks to meet the cab but "hey, I can just give you a ride to where you're going, where is it?" I've been to 1000 parties (many in that area) and that's how it usually is, couple of hangers-on still up, talking, maybe looking for some action, or that lone creepy guy (we used to call the Dahmers) no one really knows who they are / he is- friend of a friend, maybe some dude(s) walking and saw a party going on and slipped in for a few free drinks or whatever. That's just my gut. Popped on to see if there's been any movement on this. Happened a few miles from here. Bugs the hell outta me.
