On October 16, 1936, 26-year-old Katherine DiDonato, mother of two, was admitted to Roosevelt Hospital to be treated for complications of a criminal abortion. Katherine's husband reported that the abortion had taken place three days earlier. Detectives were told that Katherine had bought pills from drug clerk Hyman Kantor, who had then recommended Dr. Aloysius Mulholland to perform an abortion.
Katherine died at 2 AM on October 23. Both Mulholland and Kantor were arrested and charged with homicide.
