I’m a wife and a mother. If my husband was being questioned in the disappearance of a woman, during the time I was at work, would I be covering for him? I may have had my doubts and questioned my intuition, but when her clothes and body were found in my backyard and 10 other bodies were found just down the street from me, I would be f’ing OUT OF THERE! I would go to the police with everything I knew and get him thrown in jail.
Especially for her daughters’ sake.
He must have been late to dinner often if that’s the shortcoming of his that first pops into her mind.
I bet if it was one of Barbara’s daughters who were murdered by a serial killer, she’d want the help of the killer’s wife to bring justice for her daughter.
