What was the cause of Nikki Grahame's death?
Nikki developed an eating disorder as a young girl and suffered from anorexia nervosa throughout her life, checking into several health institutions over the years for her condition.
Nikki's mother, Susan Grahame, appeared on on Thursday to speak about her daughter's illness. Recounting the first time she realised that Nikki was suffering from an eating disorder, Susan said: "I first noticed when Nikki was about seven and a half. First of all, it was the expression on her face.
"She just became terribly sad and I couldn't understand what was going on and then she just [became] smaller and the school was saying that she was struggling in class because she couldn't concentrate on what was happening. That was when the battle began."
