Duluth police said an argument between Fredrick Rogers and his parents escalated to violence Saturday afternoon.
Investigators said Rogers pulled a gun on his parents, grazing his mother with a bullet and seriously wounding his father. Paramedics rushed the two to Gwinnett Medical Center, where the father later died.
The shooting occurred during the noon hour Saturday inside a home in the 3300 block of Ennfield Lane near Ennfield Way in Duluth.
Family members and neighbors told Channel 2 Action News reporter Tony Thomas that they were unaware of any longstanding problems in the family.
"We never had any problems," said Carlos Harris, a relative.
"I'm just so sad that this happened because he was a friend to everybody," neighbor Debbie McHugh said.
Rogers was being held in the Gwinnett County jail without bond. He's charged with murder and aggravated assault.
Police told Channel 2 Action News reporter Rebecca Lindstrom that the mother is out of the hospital and doing all right.
