The incident, which took place at Musa, Brown River, outside Port Moresby, saw Blackfort Bill pursue Brenton Awai with a bush knife, and severed his head, killing him instantly.
He returned to his in-laws’ house and told them of the killing.
The two had been drinking that night when Bill had an argument with his wife. He got angry when the deceased left and ran after him with a bush knife.
He was found guilty to wilful murder after a trial was conducted.
He apologised to the court for his actions and pleaded for mercy, saying he has a young family.
