Some time in February, 1916, Mrs. Ruth Camp died from complications of an illegal abortion performed in Denver, Colorado.
Dr. Bennett Graff was found guilty of murder in Ruth's death, and sentenced to 11 - 13 years in prison. Graff protested "stoutly" and appealed the conviction.
Graff was also charged in the death of another woman from an illegal abortion, but I've been unable to get any details of that case.
Note, please, that with overall public health 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.
