I am sitting on the confused fence with you!.
All IMO
Calvin was pushed/tossed down the cellar stairs after being shot. When? Early in the afternoon. Had to have been in the daytime before Pam comes home from work.
Someone did try to clean blood up in the kitchen, but it wasn't a big area.
Blood is found in the back yard, with the old gun that appears to be Edward's. The holster was in his chair, along with a piece of fish for supper that night thawing in the kitchen, the window overlooks the Phillip's back porch. He had spoken to his girlfriend and mentioned cooking fish for supper. I can't verify time of that call.
Pam comes home, killer is there, Ed sees this through his window, runs out with his gun. Doesn't shoot, nor call 911.
Ed lays in the back yard until ? Because they both wind up in Pam's car and driven away to be found burned the next day, Nov 19
Both loaded up in Pam's car .
Kit took off his dog tags and laid em on the shelf with Calvin's phone and wallet. Ok.O H and they were hung on kite string(appearing)

Pam's phone winds up in Joan's yard. Joan takes it to AT&T, several weeks later, I think.
A 22 casing was found in the ?kitchen, if I heard correctly today.
A 45 casing was found 5 months later, mysteriously. Where was that casing found in relation to this cellar door?
All those cops went in there and they looked at Calvin's wallet, did they look at/take the phone? Why not look at the item on the string?
Joan and son now get their subpoena's squashed completely and don't have to testify. Whereas, it should have been they have to come to court and can take the 5th. Why would either need to take the 5th?????
Has anyone done a timeline?
