KENOSHA, WI (WTAQ) - Killing his father sends a 38 year old Kenosha man to prison for 30 years.

The jury found Brian Novak guilty of second-degree intentional homicide with a dangerous weapon.

Prosecutors said the son punched, stomped and beat 59 year old Michael Novak in the head with an electric guitar.

The attack happened at the father’s house in September 2010. Novak and his girlfriend had been living in that house.

The fight came after several months of conflict between the father and son, some of it due to the father’s alleged sexual interest in the son’s girlfriend.

Novak was convicted last June and was sentenced Friday.
