Joy Martin

Photo of Joy Martin, an elderly woman with light skin and straight gray hair. The photo shows only the left half of the face.Name: Joy Martin.
Died: May 28, 1999.
Age at death: 69.
Cause of death: Murder.
Location: Wanganui, New Zealand.
Disability: Terminal cancer.

Details:
As she lay dying of cancer, Joy’s daughter injected her with a lethal dose of morphine.

After Joy was dead, her daughter wrote a book about killing her mother and was arrested.

Joy’s portrait on this memorial comes from the cover of her daughter’s book. It includes only half her face because on the book’s cover, her daughter used photo manipulation to combine half her face with half of Joy’s. In keeping with my policy of giving the killer as little publicity as possible, the daughter’s part of that image has been cropped out. –Editor
