It's her old man. She was subservient to him and depended on him for validation of her own life. So why would she turn him in ?
See it all the time on a lesser scale. How many girl friends or wives would turn in the old man on vague suspicion....Sure, if they knew the extent of what he had planned, but who would think that would happen....She was described by childhood friends as not too bright and her first marriage was arranged.
And this dude beat his first wife.
In a case this big they have to charge her regardless of any mitigating circumstances...Irony is she has gotten rid of the psycho hubby, but won't be able to enjoy it.
She may end of doing life for his nonsense.
