You know, I do agree with this ... but I still don't get how they could make such a bad decision, under the influence of whatever, and get so lucky in terms of disposing of any evidence, especially a body.
For a theory to answer these questions a couple of things come to mind.
First- drugs. If they provided her drugs, possibly even slipped her something, then this could lead to them fearing for their own futures (or atleast some of them because it doesn't
have to be all 3 involved even though that seems to be the most likely thing with this line of thinking).
Secondly- Bruising, scrapes, redness, swelling. If she had any of this going on then they could've feared it would be misread as some type of assault rather than her hitting her head or whatever in a stupor. And maybe that is even the missing piece of the puzzle- Maybe one of them was carrying her, pulling her, etc and accidentally caused an injury that led to her demise. Would they be worried no one would believe it's an accident? Or even if they do believe people will believe it was unintentional it still makes them potentially (and almost certainly) technically negligent (which could still lead to criminal and/or civil penalties).
And 1 and 2 could also be in combination.
I still think, until I hear otherwise, the dumpster is a potential place for a body to have been disposed. Was it checked before it was emptied? I've seen no confirmation that it was and I've read unconfirmed reports it WAS dumped before it was checked.
If so, then convoluted conspiracy theories are not necessary to explain how they could've gotten rid of a body via mystery guests, drug dealers, corrupt law enforcement, etc.. Throw the body in the dumpster with the plan to play dumb, claim she was not exactly sober but OK when she left the apartments, and then imply blame for her demise on a random stranger/homeless person type scenario. ...assuming the body is found.
But....
Instead, dumpster goes unchecked. Body goes to the landfill. Landfill goes unchecked until the point the search was looking for a needle in the haystack (there have been landfill searches for bodies that come up empty when they know the body was there). With no body/evidence found at the landfill any of the 3 that were involved can now return to Bloomington knowing a body won't be found and so no worry that some trace evidence might tie them to the crime. Iow, that would explain the bravery and gamble to return to Bloomington.
I'd say the flaw in the above theory is simply the lack of any evidence of any crime. But, maybe LE wasn't looking in the proper direction until it was too late.... if even looking for such evidence at all. That would be a question we'll likely never really know an answer to unless this goes to trial at some point. We're not going to know how hard they looked for blood, vomit, or other trace evidence and exactly how wide an area or how thoroughly checked either. Not the kind of thing they will easily volunteer either way.
