Elmhurst Police say they were conducting a well-being check Saturday evening when they came upon the bodies of 82-year-old Francis Stack, his wife, 82-year-old Joan Stack, and their two adult children, 57-year-old Mary Stack and 48-year-old Francis Stack Jr.
A caregiver to daughter Mary Stack for close to 15 years, Aguina says the Stacks children both had severe mental retardation and had been living in assisted living for several years, once their parents were no longer able to care for them.
