Detectives with the Hall County Sheriff's Office are investigating what they believe to be a murder-suicide in West Hall.
Maj. Woodrow Tripp said Harold and Linda England, both 62, were found dead at their home Friday at 3633 Pleasant Hill Road near McEver Road.
"Their son came to check on them," he said. "When no one came to the door, he used a spare key to find them."
The 911 call came in about 3:47 p.m.
The couple died of gunshot wounds, investigators said, and a weapon was found on the scene.
When asked which of the deceased was suspected of pulling the trigger, Tripp said, "We believe he (Harold) did, at this point."
There was no sign of forced entry and all of the doors of the home were locked.
Investigators said Linda England was in "poor health," and a hospice nurse arrived at the home as investigators were working.
Family members were gathered at the home after the Englands were found dead but declined to comment.
Deputies had obtained a search warrant Friday of the Englands' home to continue their investigation.
"That's a normal part of the investigation for anything that would not be considered a natural death," said Sgt. Stephen Wilbanks, a spokesman for the agency.
Wilbanks said that search is to be certain the sheriff's office can rule out other causes.
