A Canyon Country man was sentenced to state prison Monday for killing his father.

Sean Matthias Miller, 48, of Canyon Country, was sentenced to 11 years in state prison for the murder as part of a negotiated plea deal.

Miller pleaded no contest in May to voluntary manslaughter in the death of his father, Jack Miller, 74.

Deputies initially responded the initial call of a family disturbance inside a home in the 14800 block of Narcissus Crest in Canyon Country at 6:50 p.m., according to Sheriff’s Department officials.

The victim, Jack Miller, was found dead by sheriff’s deputies responding to calls of a family dispute on June 15, 2015, the prosecutor said.

Sean Miller picked up a bat and hit his father and then kicked him, according to a statement from the case’s prosecutor, Carmelia Mejia.

The case was investigated by the Los Angeles County Sheriff’s Department.
