On December 5, 1905, 19-year-old Mrs. Annie Killhoff died at her home from an abortion performed there that day. Two physicians, Joseph Vassumpaur and Charles Boddiger, were arrested, Vassumpaur as the principle and Boddiger as an accessory. Patrick Dillon was also held as an accessory. The case, however, never went to trial, for reasons not provided by the source. Annie's abortion was typical of pre-legalization abortions in that it was performed by a physician.
Note, please, that with issues such as doctors not using proper aseptic techniques, lack of access to blood transfusions and antibiotics, and overall poor health to begin with, there was likely little difference between the performance of a legal abortion and illegal practice, and the aftercare for either type of abortion was probably equally unlikely to do the woman much, if any, good.
