since we are now in yet another thread I want to make a few comments/observations.
from all appearances all the key people in question were wasted that night, however one chooses to define the term wasted. I've been there many times in the past and I can tell you from personal experience that when one is in that state, details are lost. what I did, what I had to drink, how much I had to drink, what I might have said to someone, and the order of events for the night are lost. not lot due to any convenient excuse but when one is in a blackout, the brain loses its ability to remember deetails.
countles people are sitting in prisons doing time for crimes of which they have no recollection. countless people have woken up in a hospital bed not recalling that they drove and got into an accident. none of this amounts to any legal defense, it is just fact.
I don't trust anyones timeline from the night unless it was captured on a video camera. seconds become minute, minutes become hours and it is all a blur.
I seeriously doubt these guys could have had the presence of mind (or lack thereof) to have formed a plan at 4 something in the morning to dispose of a body. sure it is possible but I think it highly unlikely.
what appears to me (and I am not bashing Lauren) is that she was on a mission to party and it looks lik she wore out her welcome everywhere she went that night. the more sensible in the crowd called it a night around midnight. a handful of peope were (apparently) still awake at 4 a.m. that does not mean they caused her any harm. who knows what she did after she left that last known location. she could have met up with a stranger under the guise of someone offering a ride or even more party favors (if you know what I mean).
I just have a hard time believing that this group caused her harm or disposed of her body with so little time to formulate a plan, to actually carry it out, and still three weeks later, no one is spilling the beans.
