Authorities claim a California dad used a knife to decapitate his 1-year-old kid

SACRAMENTO,  Calif. - A man has been arrested on suspicion of beheading his  1-year-old son,  authorities in Northern California  said.

The Sacramento County  Sheriff's Office said in a statement Friday that  officers, responding to an early morning disturbance  call, found a woman outside a home who told  officers that her husband Andrey Demskiy, 28,  had attacked him and  his mother.
Officers forced  entry into the  North Sacramento County  home when they learned Demskiy was inside with the  child. As they took him into custody, they found a  "child's severed head" in the  room where Demskiy was  being held.
Detectives said Demskiy used a knife to  decapitate his son after his wife and  mother fled the  home, according to the  release. He was in custody and ineligible for  bail and was  due in court  on Tuesday.
The sheriff's department and the county public  defender's office did not respond to emails seeking information  about whether Demskiy had an attorney who could speak on his behalf.
