I agree that they should have been watching him the whole time. I too do not understand why no one has answered where the wife was at the time and where is she now. One neighbor even alluded to the fact they have a small child. Anyone else heard this? I can't imagine a murder happening at my house and not being aware of it and my house is much larger than his. Also, why would the pregnant girl go with him to his house if they were not on friendly terms?
