I really want to know how the husband and three older children didn't know anything about this. 
From what I understand when the husband went to jail his wife and kids moved into HIS house.
He was sentenced to 9 years in the poky and she lived there for perhaps 7 years or so. She moved out 2 years ago leaving the home empty and when husband got out of jail he returned to the home.
It has been reported that the cellar was fix up as an apartment and through the years other people had rented it out.
It was the husband that found the bodies when he went to clean up the place when he got out.
I with hold any judgment simply for the fact of the mug shot that to my mind shows a woman totally confused. Sort of like renting out a relatives home for a few years and the new renters find body's in the basement and the police say you put them there.
Have to wait for DNA tests and total investigation before calling her any names.
