OK, my brain is in overdrive! Still reading past threads, on #15 now, so I'm almost there!
I won't think anybody's ideas are crazy, unless I get told bumble bees with semi-automatic weapons are responsible for these murders.
Plenty of us have tried to figure out who and why the main target was. Gary has been the person many people think could be due to his dabbling in drugs other than pot. Some have suggested Kenny might be to blame, and some have mentioned DS.
As far as I know, nobody knows for sure how long Gary had been in town. We don't know if he came to help his cousins out, and had been there for a week, or if he had relocated and was living with Chris or living in Chris's former home. Plenty seem to think Chris and Dana had moved back in together, but no confirmation on that. I believe Chris's home is a 3 bedroom, so plenty of room for two bachelors, and one bedroom for an office.
I personally don't believe Kenny had anything to do with the murders. I think he preferred the camper to sharing a larger place with Chris, or nephew BR.
I cannot see DS as being capable emotionally or physically to have killed anybody.
And I think the two FB threats are just baloney like so much of everything else that's on there. I'm still leaning toward ex-LE or people hired from out of town to carry out the murders hired by a business acquaintance we may not even know about. I'd bet my last nickel it's not family.
OK, end of babble! Maybe someone can expand on these ideas, or come up with a new angle not yet discussed.
