When Jim Crabtree learned last May that his mother and wife had been shot by his father, who then committed suicide, he felt not horror, but relief.
Crabtree had been struggling to take care of his 62-year-old wife, Rita, who was diagnosed with Alzheimer’s disease six years earlier. His parents were able to watch after her each day while he was at work. But his mother, 80, was forced to use to a wheelchair with severe joint pain and arthritis and his 84-year-old dad had begun to develop dementia.
