Maybe she killed herself because A. her child is missing; B. she was stunned and wounded by the brutality of Grace's inquisition; and C. the two together were more than a young woman in the middle of a "messy" divorce could handle. Maybe she just took a deep breath and looked square in the eye of sheer, rabid MEAN and without her child, couldn't quite see the point in surviving. I don't know why she killed herself, and neither does Nancy Grace, but I feel very sorry for this young mother regardless. I hope her child is found safe and returned to what is left of his family soon. And I wish we could all learn not to be so damned quick to rush to judgement.
maybe D. she had something to do with the the child being missing.
