ELMHURST, Ill. — An 82-year-old suburban Chicago man shot and killed his wife and two adult children before turning the gun on himself, DuPage County Coroner Richard Jorgensen said Sunday.

Francis Stack killed wife Joan Stack, 82, and their children Mary Stack, 57, and Francis Stack Jr., 48, Jorgensen told the Chicago Sun-Times (http://bit.ly/1rHPkXt) after autopsies scheduled Sunday. Police officers performing a well-being check found the four family members' bodies in their Elmhurst home Saturday evening.

Elmhurst police said in a statement that officers found the victims "with visible gunshot wounds." Police recovered a weapon at the scene.

Sunday afternoon four white crosses with the victims' names were set outside the home.

Neighbors called the Stacks loving and doting parents.

"They were good people," neighbor Jane Bock, 89, said. "They were so good to those kids. That was their life. It was built around those kids."

Kim Zoeller, president and CEO of the Ray Graham Association for the Handicapped, said Francis Stack Jr. and Mary Stack received services and housing from the organization for decades.

"The family was very involved and continued to be very involved," Zoeller said. "They were a very dedicated family to their children. We are all very shocked and very sad about what has transpired."

Peter Sterchele said he couldn't ask for better neighbors than the Stacks.

"They were very great people," Sterchele said. "They were very humble. They were quiet but not overly quiet. They were nice."

Elmhurst police said their detective section was investigating the deaths.
