It has been said by neighbors that they hardly ever saw the family outside - maybe once or twice they saw Rusty playing basketball with Noah. So it probably was hard for anyone to really know what was going on with Andrea or the family, unless they were close friends or family.
I know they were hardly ever outside. My point is why? Why keep kids cooped in? In that little bitty house? It's a nice neighborhood. Kids are out playing, people in their yards, cutting their grass, etc. What was Rusty-OJ-Van Dam-Yates (ROVDY) up to? What kind of dad doesn't even walk around the block with his children? Ride bikes with them, etc? Looks like maybe he was piling the pressure on?
At least walk to the park down the street? This is a real nice area. The kids were killed in June. Daylight savings time and lot's of light after "ROVDY" got off work. Why keep them in the house? Why not help his wife? Get them out of the house. Take some pressure off of her? Where was this guy?

Why not put a camera in every household and let the social workers watch your house...
