- Domestic violence among elderly couples was brought into focus by the death of 81-year-old Mary Russell in 2010.

- Mrs Russell, of Leigh-on-Sea, Essex, made eight 999 calls in the seven months before she died.
- She first reported violence to police in 2003, when she was found standing on her doorstep with blood pouring from her nose by a neighbour.
- Her husband, Albert Russell, was arrested after his wife's death but it was decided that there was not enough evidence to prosecute the 88-year-old, who has since died.
- A serious case review found police were failing to deal with the hidden problem of domestic violence among elderly couples.
