On September 24, 1927, 35-year-old Martha Kohnke died in Chicago from a criminal abortion performed that day. Nurse Emma Schultz was held by the coroner on October 5.
Schultz had also killed Mary Bambrick on October 5, 1911, but that case never went to trial.
Keep in mind that things that things we take for granted, like antibiotics and blood banks, were still in the future. For more about abortion in this era, see Abortion in the 1920s.
