In the early hours of Friday morning, John Tabbut made a desperate 911 call.
"I thought I had an intruder in the house, and I shot the intruder, but the intruder's my wife," Tabbut said on the 911 call.
She was actually his fiancee, 62-year-old Nancy Dinsmore.
"We were supposed to get married this Saturday. Oh, God," said Tabbut to the 911 operator.
Startled by a noise just before 3 a.m., Tabutt fired a single shot with his .38-caliber revolver at a moving figure in the hallway.
But instead of shooting a stranger, his fiancee was shot in the chest
"Is she conscious right now, yes or no?" asked the 911 operator.
"Honest to god, she looks dead," Tabbut responded, "No she's breathing, she's breathing, hang in there honey, hang in there."
The ambulance arrived within minutes, but it was too late.
Fire units arrived to find that Dinsmore was not breathing.
The Winter Springs Police Department believes Tabbut's grief was genuine.
"The initial investigation and site at the scene does not indicate any type of foul play," said Chief Kevin Brunelle.
In a telephone interview, Dinsmore's daughter Arlene said, "She was a good mother. She was a good person."
Nancy Dinsmore will be laid to rest this week in Maine where she'll be buried next to her first husband of 35 years.
