Amanda Rice Stevenson is 96 years old.
She also allegedly shot and killed her nephew last night by firing a round from a .357 Magnum into his chest.
St. Augustine Police Department spokesman Mark Samson says the cops got a call just before 9 p.m. Sunday about a possible heart attack at a house in St. Augustine.
Instead, police found 53-year-old John Westley Rice dead on the floor, with blood coming out of his mouth and multiple blood splatters around the scene, Samson says.
Stevenson, who police found in another bedroom in the house, was taken from the home while cops collected evidence -- including the .357 Magnum handgun -- and she was eventually determined by police to be the shooter.
Samson says Rice was shot "over a domestic situation" while he was lying in bed, but exact details of what happened haven't yet been released.
Rice's wife told police her husband was watching football when she left the house at 5:30 p.m., and when she returned at 8:45 p.m., she found her husband lying dead on the bedroom floor, leaning against a door.
It's unknown how many times she's been arrested since her birth in 1915, but yesterday's murder charge marks her third arrest in St. Johns County, according to records from the sheriff's office.
An arson charge from 1995 was later dropped, and her other arrest, in 2007, doesn't come with details.
