Nurse convicted of insulin murders

Victorino Chua, a nurse who described himself as evil, was convicted of using insulin to murder two patients at a British hospital in 2011. He was cleared of a third murder charge but convicted of attempting to cause grievous bodily harm to that patient.

Chua, 49, was found to have injected insulin into saline bags and ampoules while working at a hospital in Stockport. Other nurses who were not aware of the tampering then used the bags and ampoules, leading to inadvertent insulin overdoses.
