Troopers were called to the house when a family member asked them to do a welfare check.
Monroe County Coroner Bob Allen said the couple may have been dead for a few weeks.
Allen also believes the deaths were the result of a homicide-suicide.
He said Diana Buckley, 60, shot Michael, 62, and then herself.
The coroner said there was a note left behind which stated the couple had medical issues. The note also stated that they were now "in a better place."
Neighbors were shocked to hear the news on this quiet street.
"They were nice people. We never had a problem with them. They practically stayed in the house all the time. Sometimes you would see them come and go, but in the winter time? No. They were old," said Vicky Williams, a next-door neighbor.
The coroner is not sure when the couple died.
However, he said there were letters in the mailbox post-marked from February 5th.
Neighbors said they had no idea, especially because the past few snowstorms someone even came and plowed the driveway.
An autopsy for the Buckley's is scheduled for Monday.
