A Glenburn man told cops his demons told him to “just do it, kill her, put her out of her misery.”
Ethan Herbert, 19, was arrested after allegedly trying Sunday to kill his grandmother with a hatchet and a knife.
Herbert faces charges of attempted murder, domestic violence elevated aggravated assault, and domestic violence aggravated assault.
The grandmother was taken to the hospital, where part of her skull was removed.
She had been trying to keep her grandson from fighting with his grandfather when she was allegedly attacked.
The grandparents had banned him from their house before the fight.
Cops said Herbert blamed “The Grim Reaper” for ordering him to attack his grandmother.
Police said she tried to escape as she saw him throwing a knife at her.
During the attack, Herbert said “I’’m sorry Grammie, but I have to,’” the woman told police.
After he said that, he started walking toward her with a “hatchet swinging it violently at her head and arms,” a police report said.
