Lorna Dawson was a student in Edinburgh in 1977, when 17-year-olds Helen Scott and Christine Eadie were murdered after a night out at the World's End pub.

Decades later, she helped to convict the women's killer - using pioneering techniques to identify soil samples that had been taken and retained from Helen Scott's bare feet.

Lorna has since reported and advised on over 150 court cases, as professor and head of soil forensics at the James Hutton Institute.

She also talks to Anna - in this fascinating episode of OnFARM - about how soil forensics can be used to help fight rural crime such as machinery or metal theft.
