A court sentenced a former top bureaucrat to six years in prison Monday for killing his socially reclusive son in Tokyo earlier this year.

The Tokyo District Court found that Hideaki Kumazawa, 76, a former vice minister for agriculture, forestry and fisheries, stabbed his 44-year-old son Eiichiro in the neck and chest multiple times on June 1, causing his death from massive blood loss.

Prosecutors had sought an eight-year term. While acknowledging that the son's violence at home was behind the murder, they noted there were other ways the situation could have been resolved.
