This is JMO, and/or gut feelings, but I can't get over that these murders were "personal" and not about business. ( I could be wrong and have been before).
Some things that make me lean this way are:
Covering Chris Sr. with a sheet. They beat him, shot him and who knows what? But someone couldn't look at him after that. To me, that's a sign of remorse (small, but still there) someone wasn't as cold-blooded as the others.
Another reason I feel this way is the babies were left alive.
IMO, CRsr and Dana, fought like hell to save their family. The killers knew they would, that suggests to me that someone knew them personally.
The number of shots to HHG ? That to me was personal to. I'm an outsider, looking at her as a young, caring, mother. A little nieve, not very mature due to her age and upbringing, didn't even drive a car. Kinda "stuck" at the house and situation she was in. Who? would have that kind of hatred for her?
KR, shot once, sounds like they just wanted him dead and out-of-way as quickly and painlessly as possible. Again, to me; a sign of some kind of caring.
HR is the only one I feel was shot while she slept another sign they were easier on her.
Gr, FR and CRjr, I feel, there was some hatred for them to.
I can't get over that from the beginning, the main reason or plan was the murder of this family.
What do the rest of you think?
