The only thing I've really noticed on the threads is that just about everyone's talking about the England guy, for reasons having nothing to do with "the focus of the investigation." I haven't seen any report of an acutal investigation, so maybe I've missed something other than all this speculation. If so, I'd be happy if you link it here.
So, assuming I'm entitled to speculate as much as the next guy (or gal), here's why I think Alvin Watts is the more likely shooter:
1. He's almost 20 years older than England.
2. His facebook posts sound like he's a VERY angry, thuggish-type guy with a pretty out of control temper. Frequent fights and confrontations with little or no provocation. Even his ex-girlfriend posts that it's his own fault she broke up with him because he bullied and threatened a 68-year-old heart patient. That's just one example of about 4 or 5 I found in reading just a couple pages of his facebook posts. It sure doesn't look like he had many friends in that town.
3. By contrast, England's facebook page seems to show a guy grieving over the death (suicide, I believe) of his fiancee, the mother of his illegitimate infant child. Lots of posts about the stress of him trying to care for the baby and be a single father. Lots of posts about the grief of losing his fiancee. Lots of posts about grieving the killing of his father. Some posts about him thinking about "ending it all." He sounds depressed and suicidal, not really rageful or even angry.
4. I don't see any messages on England's facebook page about him being involved in fights or confrontations.
5. England's facebook seems to have a lot of local friends and family members trying to help and support him.
6. The white truck, reported to have been the getaway vehicle in the shootings, belongs to England. Just another reason I think it more likely England was driving the truck and Watts was shotgun...literally.
Based on all the above, my speculation is that an older, possibly sociopathic, possibly with criminal background, Alvin Watts meets England somewhere, forms a friendship with him, and is the very dominant one in the friendhip. Purely talking out of my hat here, like everyone else, but I can see Alvin Watts being the shooter, and being a pretty typical multiple shooter, as far as typical goes there. I don't see it as easily with the younger guy, England.
Very good analysis.
Watts would seem to to the leader.
I read all their facebook posts, going back 6 months, and I am really surprised either of them would do such a thing as murder. So very sad.
