Investigations into multiple killings in Mthwalume on the KZN south coast have taken another grim turn with the discovery of a fifth body. The dead woman's remains were found in the veld less than 24 hours after Tuesday's discovery of a fourth murder victim. Kwazulu-Natal SAPS Spokesperson Thembeka Mbhele says it cannot yet rule out the possibility of a serial killer. She has urged the community to remain calm and be vigilant.
