I watched it again last night - so sad. I knew (IMHO) the husband did it from the get go. Just a hunch I guess, but the blood on the bed (shot), the missing daughter, and blood spatter in the van. But what convinced me, is where her body was dumped - in his trash bin at work! He also showed no real concern or signs of emotion for someone he loved so dearly. In my heart of hearts I believe Abby was dumped alongside her mother - they just didn't find her.
