The partner of Holbrook woman Rachael Slack has issued a statement after a jury found she was unlawfully killed.
Robert Barlow said the findings of an inquest at Derbyshire Coroner’s Court should be used to help police safeguard potential victims.
Rachael Slack, 38, her former partner Andrew Cairns, 44, and their son, 23-month-old Auden, died from multiple stab wounds.
They were found at a cottage in Well Yard in Holbrook on June 2, 2010.
Jurors decided Auden was also unlawfully killed and Mr Cairns, who was found with them, took his own life.
