Demonic dad allegedly beheads 1-year-old son with knife after violent attack on wife, mother-in-law: sheriff

A demonic California dad has been arrested for allegedly beheading his 1-year-old son Friday in an early-morning frenzy of violence that also injured his wife and her mother, according to police.

Andrey Demskiy, 28, is accused of first attacking his wife and mother-in-law just after 4 a.m., the Sacramento County Sheriff’s Office said.

The two women fled the residence to await authorities. Demskiy refused to answer the door for responding sheriff’s deputies.

They “forced entry” into the home upon learning the tot was still inside with his father, who may have “possibly injured the child after throwing him,” the sheriff’s office said. Demskiy was found “uncooperative and physically resistive.”

They allegedly discovered the demented dad and the severed head of his young son in the bedroom, according to the statement. He allegedly used a knife to carry out the sick killing.

Demskiy was taken into custody and booked into Sacramento County Main Jail. He is ineligible for bail, the sheriff’s office said.

The alleged infanticidal maniac’s mother in law was transported to the hospital for injuries that were considered non-life-threatening.

Demskiy is due back in court on Dec. 24.
