A court has been shown footage of a former primary school teacher, who is alleged to have stabbed and killed her long-term partner, then purchased 50L of compost from B&Q.
Clips show Fiona Beal, 49, entering and leaving a Northampton B&Q on 13 November 2021, where she bought compost, decorative stones and bark chippings.
She is alleged to have stabbed Nicholas Billingham in the neck 12 days prior, on 1 November 2021.
Jurors were told last week that remains of Mr Billingham were found buried in the garden of their home.
