The trial has opened for Cody Molica, 39, accused of killing his 80-year-old father, Richard Molica, in Rohnert Park in January.
The Press Democrat reports prosecutors argue Cody Molica shot his father and staged the scene to look like a fight, noting he waited 15 hours to report the death. The defense claims Molica acted in self-defense, alleging the victim fired first.
The incident followed a domestic violence arrest involving the father and son just days earlier.
