First I heard of her, but I searched and she had suffered colon cancer. It may have returned with a vengeance, or the treatments did her in.
R.I.P.
Was she murdered? During the heyday of gossip columnists like Hedda Hopper or Walter Winchell, their columns would never say that, say, Darryl Zanuck had sex with a 16 year old girl. It would be implied but you would have to read between the lines. Kyle Roth showed no such restraint. You can make a lot of enemies that way. Unless she had some "dead man's switch", there could have been a hit on her, perhaps not as blatant as what happened to Jeffrey Epstein or Whitey Bulger. The "dead man's switch" may be what keeps Julian Assange and Ghislane Maxwell alive.
