Such an awful story. In brief: a woman, Tara Newbold, complains repeatedly to the police that her partner is violent but the police do nothing. She is then found dead and despite the fact that she has 37 injuries on her body, including seven broken ribs and a partially collapsed lung, the coroner decides that the cause of death is cocaine toxicity. The partner is charged with, and found guilty of, "grievous bodily harm with intent."
