I have no idea; thought maybe I just 'missed' her. Perhaps she is not alive; even if she were divorced; she would be mentioned: so maybe 'not alive' is the case.
You would think her status would at least, have come up somewhere by now.
Berg's mother was mentioned on the day he was brutally murdered. The papers said she was to distraught to be interviewed. My heart goes out to her for the loss of her son. I hope she's not as deluded as her husband.
