Nursing home team leader Garry Davis, told his Facebook friends that ‘I hate old people' and days before two patients in his care were found dead in their beds, he predicted they would die. Those facts were enough to put him in the frame as a doctor became convinced that foul play was responsible for the deaths of these two patients. The patients, whilst suffering from dementia, were otherwise in good physical health. Davis argued that the text messages were ‘black humour'. But the judge did not believe him. He killed for the sake of it – and could not resist flaunting the power he had over the life and death of Gwen and Ryan. Davis, 27, began his sentence in 2016 and won't be due for a parole hearing until 2046.
