COLUMBUS, Ohio -- There are new questions about the mental health of a grandfather charged in the murder of his 19-year-old granddaughter.
Family says 72-year-old Booker Moody suffers from dementia and thought his granddaughter was an intruder.
"It was an accident, that's how I look at it. He didn't know who was at his door,” said Moody’s daughter Traci Brown.
He's charged with killing his 19-year old granddaughter Wednesday night.
"Everyone has the right to defend their home but you need to make sure what you're shooting at,” said Eric Delbert, a law enforcement officer and owner of L.E.P.D. firearms.
Delbert said this case may be tough to decide.
"It's more than likely it's not a murder charge as much as it is a negligent but that's for the prosecutors to figure it out. It's unfortunate. It's unfortunate all the way around,” said Delbert.
Family said Moody suffers from dementia.
"The prevalence (of dementia) increases with age,” said Dr. Marian Schuda at Riverside Methodist Hospital at OhioHealth.
Dr. Schuda has not treated Moody but specializes in senior health. She said if family knows a loved one has dementia they need to take extra precautions right away.
"Really have to see the household dangers differently when you have someone who might get confused and be frightened,” said Dr. Schuda.
Moody's daughter says they took care of him from time to time. But on August 15th, cops are still trying to figure out why the 72-year-old grandfather fired his shotgun through his window, killing his granddaughter.
"I wasn't here so I don't know,” said Brown. "He said he doesn't know what happened."
This weekend, he remains behind bars.
"It was just a misunderstanding. it was an accident,” said Moody’s daughter.
Prosecutors said they're still waiting for police to finish the investigation before they can decide on keeping, changing, or dropping the grandfather's murder charge all together. His arraignment has been rescheduled for this Monday.
