It's interesting how we can see things so differently.
Looking at all the details released thus far, I don't see this as a video-game inspired thrill kill by a 35-year-old loner husband and father at all.
Looks more to me like CV wanted to erase his wife and son from his life so he would have more money to do as he pleased, and possibly to play with women who he found more palatable than his wife.
It appears that CV liked to talk to people, though he clearly put some people off. His brother calls it "socially awkward", sounds more like "total ahole" to me (but I'm not family, of course).
Plus, CV chose to work in a retail and customer service environment, there are photos of him with friends and family on FB, Shanna's dad seemed to have been taken in by him, etc.
From the just-released capital murder warrant, we now have some confirmation that CV complained a lot about his wife's looks, her attire, how she organized the house, how he wanted to kill her -- indicative of a controlling and possibly abusive man who resented his wife, as many of us suspected.
We know now that CV had been thinking about killing his wife for months, yet he did so after his wife decided not to go back to work and after selling their CO home ($$$). He attempted to clean up evidence of his horrific crimes, staged a crime scene, and liked to police.
I don't have an opinion about whether CV might have some mental illness at this point. But, I do believe he was probably seriously into drugs, along with alcohol, and he knew exactly what he was doing.
