Sue Lawford had only met Sharon Johnston once before she helped her travel thousands of miles to end her life, risking a 14-year prison sentence in the process. The retired teacher and NHS worker decided to chaperone Sharon - who was paralysed after an accident at home - to Dignitas believing she deserved a "choice" in how she died.
Sharon's accident was a freak event that could have happened to anyone. She'd gone upstairs to wash and change and put her pyjamas on early but as she came back down, she lost her footing and crashed headfirst to the bottom. And that was it, she just couldn't move. She'd fractured several bones in the top of her neck and was paralysed.
She was left with virtually no movement in her body, apart from some movement in one hand which allows her to operate her specially adapted wheelchair. She was doubly incontinent and relied on carers four times a day.
