Some of these do appear to be mysterious. Dorothy Kilgallen (in the last paragraph) would not seem to be because of the timeline. However, as a teenager I do remember thinking at the time that it was weird that she had died of a combination of alcohol and sleeping pills - ruled accidental. Weird to me because she had been so outraged and disgusted that the actor Alan Ladd had died of same. She had said it was totally preventable and that no one should die that way. She said it was too easy to prevent that happening.
