I agree with you about his idiotic FAKE reason for placing SW in a shallow grave -- to fool LE that it was a spontaneous crime of passion.
BUT I would also like to add that I think he put Shanann's body in a shallow grave because he wanted to disrespect her in death as he was unable to in life due to the fact she was a strong character who stood up to him.
CW wanted to demean and desecrate her in death because he could not even be a quarter of the person she was in life and he resented her for that.
He didn't care if her body was eaten by wild animals because that was his evil, cowardly way of demeaning her and invalidating her. Just as he defecated close to her grave site and shoved her two precious girls into oil tanks. He KNEW better than anyone what crude oil would do to their little bodies. All pre-meditated.
I really hope he gets his just desserts in prison instead of donning his new mask as "Chris Found Jesus" or studying to be a preacher. I strongly believe in an eye for an eye.

CW is very lucky he didn't live in Colorado in the 1800's. He would have probably had a maximum of two days to live from the time his sorry a** was thrown in a county jail for murdering his pregnant wife and little girls.
Justice would likely have been served up frontier style, with an unknown group of men taking him from the jail during the middle of the night and the sheriff never bothering to search for the group of unknown men. Done.
