The woman wanted by police in connection with the rape and murder of a neighbour, who was killed in a suspected life policy scam, could face investigation for more similar cases.

Nombuso Zondwa Ndwandwa, 41, is believed to have conspired with the late Wanter Dlamini's daughters Nonhlanhla and Mapume Mthunywa to take out a death benefit policy on her.

Police said when the policy matured, they plotted to kill Dlamini.

Dlamini, 62, was raped and murdered last month. Her body was later dumped on the side of the road to make it look like she was killed in a car accident.

This would have enabled the claimants to cash in on the R80,000 insurance payout.

Mpumalanga police spokesperson Brig Leonard Hlathi confirmed yesterday that they were investigating a number of cases, including the poisoning of Dlamini's eldest son three years ago.

"For now we cannot say much, but we can confirm that investigations into Ndwandwa include those of two other deceased people on whom she also took out life insurance.

"There's another one involving Dlamini's surviving last-born son. For now we are asking the community to help us find her so that she can help in our investigations. We will leave no stone unturned."

Hlathi said Nonhlanhla, 30, confessed to the murder and revealed how she held her mother's legs while her boyfriend and that of her sister, Mapume, gang-raped her.

Nonhlanhla, Mapume, 39, and Nonhlanhla's 36-year-old boyfriend have since been arrested and appeared in the Barberton magistrate's court. They have not been asked to plead and are expected to apply for bail next month.

Dlamini's other daughter, Bessie van der Merwe, said her "loving and forgiving" mother was killed like a dog.

Van der Merwe told Sowetan on the day her mother died, she tried to talk her out of going to her now arrested daughter's house in Extension 11 in Barberton.

Police are also looking for Moses Nkunzi Mosemba, 36, regarding the case. Anyone with information should contact detective Lt-Col Senzo Dawie on 071-685-1364.
