Watched it last night. Very disturbing and can't stop thinking about it. I just googled it to find out more but to be honest the documentary was pretty comprehensive.
Initially I felt sorry for Shan'ann, with a failed marriage at a young age, but then I admired her for getting back in her feet and building her own home. However, there was a stage during the documentary that I started to dislike Shan'ann. She always had to capture every event on camera, which was intrusive and forced, and she seemed very assertive, maybe controlling....perhaps emasculating. However, I never believed she killed the girls. I've watched enough crime programmes to suspect him, not immediately but quite soon. There's usually a reason why a middle aged man suddenly gets into shape....usually a health scare or affair!
It was sickening how he planned to kill his wife and then felt he had to kill the little girls too. And then to think he could beat the lie detector! His cold callousness was the worst...
The thing that puzzled me, which I read when I googled was the fact they filed for bankruptcy two years after marrying, yet they both worked and she had her own large house prior to marriage.
