Respectfully snipped:
This is a very interesting theory and one I had certainly not considered. I wonder if LE has looked into the background of anyone connected to Allison to see if they can discover anything potentially nefarious that would cause something this extreme. It makes me wonder, if this is the case, what on earth someone would be involved with where a murder would be considered a warning/retaliation - particularly when the murder of someone as wholesome as Allison seemed to be was the result. I mean, you see it in movies, but in real life? Scary stuff.
