A husband and wife were stabbed by their son at their homestead in Umsunduzi near Pietermaritzburg on Thursday, police said.
Witnesses alleged that they were arguing about food when the son attacked them with a table knife, said Captain Joshua Gwala.
The 65-year-old man was found inside the house with multiple stab wounds to the throat and stomach. His 56-year-old wife sustained three stab wounds.
Gwala said her body was found near the gate where she had collapsed when she ran to call for help.
The 22-year-old suspect was subsequently arrested, said Gwala. The table knife - the supposed murder weapon - was also recovered.
