The mother has taken and passed a polygraph. The police will not comment on the father or the neighbor taking one, which makes me think that they probably haven't, or the results weren't squeaky clean. Applying Occam's Razor makes me tend to believe the father and this neighbor are somehow involved. I've noticed in the interviews that I've seen of the couple that the husband rarely, if ever, looks into the camera. It's like how Susan Smith was in interviews when her kids allegedly "were kidnapped". It makes me very uneasy as to what the husband knows or might have done.
I agree.
