How Many People Did Mary McKnight Murder, and Why?



Episode 47: How Many People Did Mary McKnight Murder, and Why?

Accurately recognizing and treating many diseases, including mental illness, was not prevalent in the 19th or early 20th centuries. Rural farm communities were accustomed to injuries and illnesses that often resulted in death. Some deaths could not be explained that’s just the way it was.

 On Monday, April 20, 1903, Gertrude Murphy left her three-month-old baby, Ruth, in the care of her sister-in-law, Mary McKnight. Gertrude left the baby with Mary to help with work at a new house she and her husband, John Murphy, were building on a nearby piece of land. When Gertrude and John came back at lunch time, Mary told them that baby Ruth had died. Baby Ruth’s death was only the beginning of a cascading series of deaths that resulted in the exposure of a mass murderer living in a little town in northern Michigan.
