Emmitt Weaver tried calling a friend after shooting his wife, Betty, Tuesday afternoon.
When his friend's daughter answered the phone, the 66-year-old retiree told her he shot his wife and planned to turn the gun on himself.
In her 911 call, the woman hyperventilated while reciting some of Emmitt's last words to a dispatcher.
"Evidently him and his wife had a fight and he had a gun and the gun went off and he said she was dead and he was going to kill himself as soon as he hung up the phone," the woman breathlessly said.
Just after 2:30 p.m., authorities suited up in bulletproof vests and entered the Weavers' home through the garage.
They heard a shot -- the sound of Emmitt shooting himself in the heart.
Inside, the officers found Emmitt dead in an easy chair with a single wound to the chest. Betty, also 66, lay a short distance away, face down on the floor, with bullet wounds above her heart and in the middle of her back.
"You don't accidentally shoot someone twice," Sandusky County Sheriff's Det. Capt. James Consolo said.
Police discovered Emmitt had a second 40-caliber Glock loaded and stowed between his thigh and the chair. They found the murder weapon, a 45-caliber semi-automatic handgun, on the floor next to his chair.
Consolo said the home was clean and tidy, showing no signs of a struggle between the couple prior to the shootings.
The Weavers married and built their York Township home in 1984. They both had children from previous relationships.
Investigators learned from family members and friends the couple engaged in an increasing number of arguments in recent years, and some speculated they might have considered divorcing.
Consolo said money troubles did not seem to be a factor, though family problems might have been.
"It's pretty cut and dry," he said.
Emmitt's children -- Jason Weaver of Sandusky and Rhonda Weaver of Bellevue -- were at the couple's home with a cleaning crew Wednesday afternoon.
Rhonda came to the door, but said the family was still too upset to talk about the shootings.
"We have no statement right now," she said.
One of Betty's daughters, Angela Knittle of Vermilion, was not home Wednesday afternoon and did not return requests seeking comment.
"I feel for all the family members with the situation that occurred," Sandusky County Sheriff Kyle Overmyer said. "Hopefully we don't see any more of these."
