A 12-year-old boy in the Bolivar area was found dead of what is described as blunt force trauma on Sunday.
Now the child’s father, Chad Baker, faces charges of first-degree murder.
A relative found the boy’s body outside a barn at his grandparents’ home.
Baker is said to suffer from schizophrenia.
He has been charged in the past with endangering the welfare of a child.
He and his sons lived near Stockton.
The boys’ mother is deceased.
