Blansit confessed to killing his mother, 45, after they got into an argument over grades, said DeKalb County Sheriff Jimmy Harris.
She died of blunt force trauma with a baseball bat, Gregg said.
Investigators said they found scratches on Blansit, a student at the University of Alabama at Birmingham, when they met him at the scene, CNN affiliate WAFF said.
Mentone is a town of about 500 in northeast Alabama. Blansit’s father said his son had been home several weeks and they were waiting for his grades, Gregg said. The father was at work during the day, the chief said.
Tyler Blansit was the couple’s only child, Gregg said.
