Just as I suspected and mentioned earlier. The income they made when they bought the house drastically reduced. Unless he had a different job now then he did then, Shannan's sales plummeted. This confirms it with a combined income of 147k down to 90k. Losing 57k in a situation where one was living above their means to begin with puts you in dire financial straits very quickly.
I am totally sickened not only the fact he killed his wife and children, but how he disposed of them is so horrific and also telling. My first thought was so he was ok with going to work every day knowing his baby girls were close by and a constant reminder of what he had done. Then I realized one, he doesn't care about them and two, he had no intentions of sticking around anyway. He was already talking about selling the house. He was going to be out of there as soon as possible.
Gitana the video you posted of Bella was the saddest thing I've seen since reading about this case. It brought her to life and emphasied the cruelty and horrificness of this crime. Having 2 young granddaughters of similar age and knowing how much they adore my son and are totally daddy's girls makes it all so real to me. Such a sweet little girl and one that loved her daddy...UGH.. the betrayal here is disgusting.
