HEMPFIELD, Pa. (AP) — A man who says he fatally beat his 92-year-old father in their home because he believed his father was a vampire has been sentenced to 10 to 30 years in prison. Douglas Novak pleaded guilty but mentally ill last November to murder, arson, reckless endangerment and risking a catastrophe charges. Authorities have said he fatally beat Frank Novak with the wooden arm of a dining room chair. Novak’s lawyer said Thursday that his client was off his medication when he attacked his father. But prosecutors say Novak told police he beat his father because the older man was hiding his phone.
