Authorities say a couple found dead in a murder-suicide at George Wyth State Park in Waterloo suffered from health problems.

The Waterloo-Cedar Falls Courier reports autopsies confirmed that 86-year-old Neil Miller shot and killed his wife, 83-year-old Marilyn Miller, before taking his own life. Their bodies were found Saturday morning. They lived in Waterloo.

Police Capt. Dave Mohlis says the Millers had medical issues and that people who knew them say the couple didn't want to go to a nursing home.

They'd been married 65 years.
