The 14-year-old boy's mother, 42, was found dead in the family's corrugated iron-shack home, and the body of his three-month-old sister in a nearby field.
His 58-year-old grandmother and seven-year-old brother died in hospital.
The boy's two other sisters, aged eight and nine, ran to their neighbours during the killings and raised the alarm early on Friday morning.
