DAWSONVILLE, Ga. -- Authorities say a mother and her disabled son were discovered dead in a Dawsonville home on Friday.
The grisly scene was in the Biscayne subdivision off of Harmony Church Road near Georgia Highway 400.
The boy's father came to pick him up for regular visitation but when he got there, no one came to the door. And that wasn't typical.
The sheriff described how the father said those routine visits normally started.
"When he comes to visit, the kid comes to the door and is excited to see him," Sheriff Billy Carlisle said.
Feeling that something was wrong, the father called 911. But once inside, deputies found a devastating scene.
"Once inside the house, the deputies in the room adjacent to it saw two bodies," the sheriff said.
Detectives said Dustin's body was lying on a couch and his mother Nina Hicks was next to him on a pallet. Both had gunshot wounds to the head.
Investigators said the mother's wound was self-inflicted.
"It's pretty tragic to see that a mom shoots her own child," Wooten said.
Geraghty lives down the street and learned of his neighbors' deaths while walking his dog.
"We don't all know each other very well, maybe, but still – to hear news like this it really makes you stop and think," he said. "It's a sad, sad day."
The scene was just as unsettling for deputies.
"It's not something that I've experienced," the sheriff said. "Usually in a murder-suicide, it's couples or significant others in some type of relationship."
Officials said crews on the scene found evidence that may reveal the mother's motive.
"Basically, his health issues had gotten worse and she didn't want to be living without him," Wooten said.
Investigators didn't say if the mother left a note. They are working on establishing a timeline of when the shootings took place.
