The Waigani National Court convicted Lucy Jacob after it found sufficient evidence she stabbed her husband on his chest with a knife, which led to his death.
All witnesses who gave evidence in court said the couple had been arguing that afternoon while traveling in a PMV.
It was also put before the court that the couple had been consuming hard stuff and coffee punch on that PMV since they left the Erima Service Station.
The court however, accepted that she stabbed her late husband with the knife with intent to cause bodily harm to him after he tried to beat her up.
Medical examination of the deceased’s body stated a 22mm stab wound was found on his chest.
The offense took place around 5:30 that afternoon, a time of the day which the court said had sufficient light for people to witness the act.
It was found that after stabbing her husband, Jacob and the deceased got off the PMV during one of the stops.
Witnesses also told the court that the deceased shouted in the truck when he was stabbed.
Jacob will return to court on Oct 4 where submissions will be made regarding her sentencing. She remains in custody at Bomana.
