My bet is on Abby. She's been so super-supportive of her father from Day 1. And, her emotional states are volatile. Plus, there's the repeat act of her eavesdropping on conversations, which could very likely have fueled her suspicions and (if she did, in fact, witness Ben reading a bedtime story to Tom and showing him fatherly love after such an awful fight with her mother) her intent to coax him out of bed with the purpose of drowning him in the river. She knew him well enough to know he couldn't swim. And the blood spatter analysis likely revealed the height of the killer, which - if lower than normal - points to a child. And we don't have many key characters of a non-adult height to choose from. It will be interesting to see how this actually pans out. Im not 100% convinced it's Abby, but if I had to put money on it..... PS: I like the idea mentioned earlier that Ben would fess up if Abby is charged. Hadn't considered that, but very likely.
