58-year-old Carlo Yandolino and his wife Rebecca have spent a decade building up their special olive oil business in Newcastle, Placer County, California.

Police say that Thursday, they believe a son neighbours say Carlo 'never mentioned' turned up, shot his father in the head, hit an employee with a rock and then went on the run. Carlo died.

Robert Yandolino has now been arrested on suspicion of murder and attempted murder. Police say they have no idea of a motive for the crimes.
