An inquest found that police failings led in part to the death of Rachael Slack and her 23-month-old son Auden at the hands of her former partner.
The pair were stabbed to death at their home in Holbrook, Derbyshire, on 2 June 2010 by Andrew Cairns before he turned the knife on himself.
Here, East Midlands Today's James Roberson examines the events leading up to their deaths and speaks to friends and neighbours who believe more could have been done.
