SACRAMENTO, Calif. (KCRA) —The father of a 9-year-old boy is under arrest on suspicion he attacked and killed his own son with a hatchet while the boy slept on a couch, said Sacramento police.

"Just a horrific case," said Matt Young, a Sacramento Police spokesman.

At 11:52 p.m. Tuesday night, Young said police received two emergency calls from a residence on Atrisco Circle, in the north area of Sacramento.

A 9-year boy was found dead inside the home, the victim of "devastating injuries to his head," Young said.

"It's just awful. I can't imagine a father doing that to his own child," said Monica Roberts, a neighbor.

The father was identified as Phillip Hernandez, 36.

Hernandez broke through a sliding glass door before attacking his son, said a news release from police.

"It's a horrific story. Detectives are having a hard time and more importantly, the family is devastated," Young said.

A neighbor told KCRA3 the victim lived with his father, grandmother and an older brother.

"There is still no explanation for Hernandez's actions," read a news release from the Sacramento Police Department.
