Autopsy results confirm that an Elmhurst man fired the shots that killed his wife and adult children before he took his own life Saturday.
During a well-being check Saturday evening, officers found the bodies of Francis and Joan Stack, both 82, and two of their children, 48-year-old Francis Stack Junior and 57-year-old Mary Stack.
All had been shot to death.
The adult children were both severely disabled.
Friends say Joan Stack's health had recently declined, and she was bedridden. Neighbors say both parents were devoted to their children and often brought them back home from the facilities that cared for them, to spend time with the family.
