Thomas Cameron, who's 83, was charged with attempted murder after February's knife attack on eighty year old Doreen, who played dead to escaped after being stabbed in the neck, arms and hands in their bed.

Police found Cameron distressed, wearing a bloodied t-shirt and bleeding from a neck wound himself -  who told them 'get it over and done with and kill me now'.
