Eighty-eight-year-old Ernest Rayfield began Sunday morning in his Springfield home by asking his wife if she wanted breakfast, according to police.
He ended it by allegedly stabbing her to death in the bedroom they shared.
Rayfield then covered his 87-year-old bride, Mary Agnes, with a blanket, called their daughter, knelt by his wife's lifeless body and waited for police to arrive, according to court documents.
When questioned by investigators, Rayfield admitted to the crime and said that he "couldn't take it anymore." A source said that his wife was ailing and may have had Alzheimer's disease.
The Rayfields' daughter received a call from her father about 11:40 a.m., in which he said that he'd stabbed his wife because "he had had enough," according to court documents.
Police said that they responded to the home on Madison Road near Sherman, in Springfield, Delaware County, and found Rayfield kneeling next to his wife on the floor of their bedroom.
Mary Agnes Rayfield had stab wounds to her chest, and her upper body was "covered in blood," court documents said. She was pronounced dead there.
A knife was found on the bed above the couple, police said.
Rayfield allegedly waived his rights and told police that when he awoke, he'd asked his wife if she wanted breakfast.
Instead, he said, she told him that she wanted him to leave the house, according to court documents.
He grabbed a knife from the kitchen and when she told him to get out again, Rayfield said that he "couldn't take it anymore" and stabbed her several times in the chest, police said.
Rayfield was charged with murder and related offenses. He remains at the Delaware County Prison without bail.
The killing is the second in the township this year, after five years without a homicide.
The first occurred in June, when an Iraq war veteran was allegedly killed by his girlfriend's estranged husband.
