Water samples taken to be tested for cyanide and heavy metals in the wake of the mysterious deaths of two young Kako brothers have returned negative, but retesting is to be done after concerns were raised about the handling of the samples.
Blood samples taken have also returned negative. However, Deputy Chief Medical Officer Dr Karen Boyle expressed that a lack of specialized containers to store the water samples may have affected the results.
The doctor related that water samples were sent to the Institute of Applied Science and Technology (IAST) to be tested, but she was uncertain of the methods used by the institution and its capacity for testing.
