86 years old man is said to have killed wife 81 saying he did it because he couldn't cope with her dementia

An elderly dementia patient was shot dead in her care home by her one-armed husband who was staying with her over Christmas. Rita King, 81, was gunned down in front of frail residents by spouse Ronald, 86, who mumbled 'she has had enough' before pulling the trigger. The couple are understood to be childless and the strain of looking after his wife had taken its toll on Mr King. One neighbour said he simply 'could not cope', while another said he was 'under great stress'. Questions were raised over how Mr King, who has been arrested on suspicion of murder, was able to smuggle a firearm and live ammunition into the secure care home inside De La Mer House in Walton-on-the-Naze, in Essex.
