The woman obviously never "really" knew the man she married. I'm sure there were small, suttle hints that he subconsciously revealed on being infatuated with his step-daughter as well as hanging out in the basement (like the way he looked at her, how he touched her, the amount of attention he gave her, etc.). No telling how long he would have gotten away with this before escalating it to physical assault/abuse/rape. It would have only been a matter of time. Fortunately he was stopped.
Well, not only will he lose his wife and home, but he will lose his job and have a VERY hard time finding another with multiple felony convictions and jail time on his record. He should be charged as a sexual predator too. Jason
