Constance Margaret Fisher: A Tragic Tale of Mental Illness and Murder

Early Life

Constance Margaret Sirois was born on March 26, 1929, in Oakland, Maine. She was abandoned by her birth parents and later adopted by the Sirois family. In 1946, at the age of 17, she married Carl Marion Fisher, a WWII veteran. The couple had three children: Richard, Daniel, and Deborah Kay.

First Incident: March 8, 1954

On March 8, 1954, Constance Fisher drowned her three children in the bathtub of their home in Waterville, Maine. Her husband, Carl, returned home to find the door locked and contacted Dr. Richard Chasse, who had been treating Constance for depression. They broke down the door and discovered the bodies of the children.
  • Richard Fisher, aged 6, found drowned in the bathtub
  • Daniel Fisher, aged 4, found in bed
  • Deborah Kay Fisher, aged 1, found in bed
Constance was found unconscious under a bed, having attempted suicide by drinking liquid shampoo. She left a suicide note explaining that she had drowned the children to "save them from evil" and that God had ordered her to do so. She was diagnosed with paranoid schizophrenia and deemed unfit to stand trial. Constance was committed to the Augusta State Hospital.

Second Incident: June 30, 1966

After being released from the hospital in 1959, Constance Fisher returned home. However, on June 30, 1966, she repeated the horrific act, drowning three more of her children in the bathtub of their home in Fairfield Center, Maine.
  • Kathleen Fisher, aged 6, found drowned in the bathtub
  • Michael Fisher, aged 4, found drowned in the bathtub
  • Nathalie Fisher, aged 9 months, found drowned in the bathtub
Constance was again found not guilty by reason of insanity and recommitted to the Augusta State Hospital. ...Read More
