Police theorized she may have been sitting or standing by a
fountain in the Art Institute’s south plaza when she was attacked.
The assailant apparently then dragged her into the bushes. She
apparently was sexually assaulted, police said.
Police said thousands of persons must have passed the site and
one man told them he heard a scream about 2 P.M. but did not in-
vestigate because no one else seemed to be paying attention.


  1. The New York “seizure” and “smoke” emergency studies are re-
    ported by Darley and Latané (1968) and Latané and Darley (1968), re-
    spectively. The Toronto experiment was performed by Ross (1971). The
    Florida studies were published by Clark and Word in 1972 and 1974.

  2. See a study by Latané and Rodin (1969) showing that groups of
    strangers help less in an emergency than groups of acquaintances.

  3. The wallet study was conducted by Hornstein et al. (1968), the
    antismoking study by Murray et al. (1984), and the dental anxiety study
    by Melamed et al. (1978).

    Hafner (1988).

    1960 TV debates with John F. Kennedy—and thereby to the elec-
    tion—was the poor performance of Nixon’s makeup man.

  3. This finding—that attractive defendants, even when they are found
    guilty, are less likely to be sentenced to prison—helps explain one of
    the more fascinating experiments in criminology I have heard of (Kur-
