When I was in college, (in the 80s), a guy that I was dating, invited me to a party. We all played a drinking game, and I got drunker than I had ever been in my life. After coming out of the bathroom, I noticed everybody was gone and I asked the party thrower where my friend was. He said that he had gone 'out for burritos' and would be right back. (my 'friend' later told me that this guy had told him that we wanted to be alone). Well, things got bad real quick, and I spent the next 7 hours or so, wondering if I was going to make it out alive. but here's the weird thing...I knew if I came up 'missing, my friend wouldn't say a thing. I was on my own. This guy was a star baseball player from the town's college and I was just a local girl from the wrong side of the tracks. I was in deep trouble and knew it. This guy was a psycho. In LS's case, I think there might be something like this going on. I have hardly any doubt that at least one of her friends knows something...either who she left with or maybe where they ditched her. There was just too much interaction, too much fighting, too many hard feeings, too much lost memory. This girl didn't just vanish. I'm wondering what kind of domino effect the fight caused. It could go one of several ways...but I think that fight is the most important clue...because it shows a group mentality and frame of mind. IDK, but even for a hard partying crowd, this night seems extreme. This is just my opinion, but I know from my daughter, (who's college age), how drunk girls are still treated. They are blamed for creating drama and just about anything goes...kind of a 'you brought this on yourself' mentality. Anyway, I think LS's mother is right to be suspicious of the friends. MOO.
