Speaking outside the inquest, Lisa Martin, who first informed police of the problems at the care home, said she felt she had no choice but to come forward:
I came forward because I had witnessed too much poor management and care to vulnerable adults and I couldn't live with the knowledge any longer and felt I had no choice but to tell the police.
Morally I know I did the right thing but personally I have not worked for two years and the case has had a huge impact on my life.
However, I wouldn't want to dissuade people from doing the right thing if they see vulnerable elderly people being abused and neglected.
Speaking of her former colleagues, she added: "They shouldn't be allowed to work in the industry."
