A woman and her three daughters from Butterworth were found dead inside their rondavel on Sunday.
Police spokesperson Colonel Priscilla Naidu says the 38-year-old mother, Bongeka Buso was found hanging from a rope while her daughters' bodies were discovered inside.
She says a friend who visited the deceased early on Sunday morning made the shocking discovery.
Colonel Naidu says the bodies of her five-year-old daughter, Oratile and eight-year-old Orabile were found on their beds, allegedly poisoned while the 14-year-old Anathi was found lying on the floor next to the bed with a knife in her neck.
She says the motive is unknown, but it is suspected that it could have been driven by poverty.
The Provincial Commissioner, Lieutenant General Nomthetheleli Mene, expressed sadness and concern at their deaths.
"It is a deeply concerning and heart-breaking issue that women facing poverty can be driven to such despair. Socioeconomic challenges can exacerbate their vulnerability to mental health issues. Addressing poverty and promoting mental health support is crucial to prevent such tragedies. As we commemorate Women’s Month, I urge women to raise their voices and speak out," she said.
