1928: Fatal work of unknown perpetrator

On February 2, 1926, Alberta Handy, a 38-year-old Black woman, died of a botched abortion in Chicago.
The perpetrator was never caught.

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.
