Ok, so my theory is that based on the expert her lawyers are calling, they are going to argue that Sunny groomed/abused Holmes over the course of their relationship (probably by calling attention to the age difference/power dynamic difference when they first met), which left her with trauma that led to her making the decisions she made.
So “Battered Woman Syndrome” [1] but applied to fraud instead of assault/murder.
If that’s the case, it really seems like they aren’t going to argue that Holmes didn’t deceive and commit fraud, but that her PTSD is a defense.
Novel. This may have worked in the 1980s, the era of the the Twinkie defense [2] and other ways of arguing diminished capacity, but I’m not sure it’ll be successful here.
