Is known to be a fact that Sandusky’s wife knew?
No, but I think a lot of folks assume it because he was allegedly abusing boys in his home, right under his wife’s nose, on a regular basis. I’m not so sure, since not only is love blind, but it’s blinding. People often just can’t perceive bad things about the people they love, even if the truth would be obvious to everyone else.
I have to admit that I do not know for a fact that she knew. I believe there was enough evidence that she looked the other way, especially when Sandusky would take these kids down to the basement. What wife wouldn’t ask questions?
