Agreed. Too bad (?) there's absolutely no evidence that anything of the kind happened.
The problem with that whole scenario -- and most people's slavish adherence to it -- is that, while it's consistent with what we know (Lauren being intoxicated, other people being around her and aware of her intoxication, the same people not seeming to be entirely forthcoming with police later on), there's no direct evidence of it. No body. Nothing of Lauren's found in the possession of someone who shouldn't have it. No phantom cell phone pings placing Lauren or anyone else in an out-of-the-way location. No telltale internet searches for "reviving someone after an overdose" or "how to dispose of a body." No blood, vomit, or other body fluids indicating that Lauren had an adverse, possibly fatal reaction to anything she was taking. Zilch.
