Old grudge possible motive in triple murder

Father, sons fatally stabbed in Shaanxi province on Lunar New Year's Eve

A court in Shaanxi province said on Thursday that it will review a ruling made in the 1990s that might have been at the root of a triple homicide during this year's Spring Festival.

A man identified in local media as Zhang Koukou, a villager from Hanzhong's Nanzheng district, allegedly stabbed three neighbors with a knife on Feb 15, which was New Year's Eve on the lunar calendar.
