FRANKFORT, Ky. (WKYT) - UPDATE:
After an investigation and autopsies, the Franklin County Coroner thinks both Charles and Dora Kelly died from natural causes.
He says Charles Kelly died from underlying health condition from lung disease complication dehydration.
The coroner believes he died about three days before his wife, Dora Kelly.
He also thinks Dora Kelly died from natural causes from an enlarged heart.
Both were tested for carbon monoxide. Those results show 5% or less from both of them. We're told that consists with a person that smokes.
Days after their bodies were found investigators are still trying to determine how a Franklin County couple died.
Sheriff Pat Melton says they should have a better idea once toxicology results come back.
"Hopefully the autopsy will be very revealing on this investigation," Melton said.
When police and fire vehicles surrounded the home on McCann Lane Friday afternoon neighbors didn't know what to think.
"I was shocked, what happened, nobody knew," said Debbie Redmon. She has lived next to 76-year-old Charles "Porkey" Kelly, and his wife, 55-year-old Dora Kelly, for years.
Sheriff's deputies went to the home on a welfare check and found the bodies of the couple. Sheriff Melton says there were no signs of foul play and Coroner William Harrod says the cause is undetermined. Melton says his deputies had been to the home before, at least four times in February and a few more times in March.
"One was an attempt to hurt herself, she was actually transported on that one," Melton said.
During one of those visits a deputy called for help.
"The living conditions were so deplorable there that one of the deputies actually called adult protective services," Melton said.
While authorities wait for a cause of death neighbors say they'll miss the quiet couple who kept to themselves.
"They were super nice neighbors, they didn't bother you," Redmon says.
The coroner says he should have a preliminary cause of death in about a week, but the official cause could take more than a month.
The Kellys were buried Thursday. Instead of flowers their family asked for donations to the Franklin County Humane Society.
