Having dealt with a number of homicide cases involving women in the past, the court said the practice has become widespread when sentencing a Finschhafen woman this week to 15 years in jail.
The court sentenced Mosoreng Lindong of Laleng village after she pleaded guilty to the charge of manslaughter.
She admitted to killing an Osemba Urah on 17 February, 2017, at Ass Mambu black block in Lae.
She spent 8 months in pre-trial custody and will serve a remaining balance of 14 years and 4 months in jail.
Her co-accused was unable to appear in court as she had recently given birth and was still recovering. She will be sentenced by the court at a later date.
Lindong and three others attacked the deceased at her house after they broke the door using a timber.
The same timber was used to hit the deceased on her head several times, before dragging her out of the house where one of them stabbed her with a knife.
The assault continued outside when cassava branches were used to hit the deceased, causing her to fall unconscious.
Neighbours came to her rescue and took her to the hospital however, she succumbed to her injuries on 8 March, 2017.
