This whole thing was just awful I've watched a few videos about it too and apparently he says he could've killed anyone and been justified for it because of his love for Nicole? And then apparently when he arrived in Colorado Shannan had a headache and he said he was giving her painkiller but it was actually a drug that would've made her miscarry because Nicole said she wanted to give him his first son. But because he confessed everything they didn't even bother investigating her.

Although I do believe if it wasn't Nicole he would've met someone else and still done it, apparently he was bisexual too and had an affair with a man.
