Soil found in murder suspect Adrian Muir’s car was very similar to earth in Pamela Jackson’s moorland grave in Calderdale, a court heard.
Samples of soil were discovered on mats in the footwell of Muir’s Kia and on gloves inside the car.
A soil expert told Muir’s murder trial the dirt was compared to earth taken from Miss Jackson’s grave on the moors near Ripponden.
Prof Laura Dawson said she rated the similarities between the grave soil and the dirt found in Muir’s car at 8.5 out of 10.
Prof Dawson said the samples taken from the grave site were of soil from underneath the surface, meaning a person would have had to have been digging to get it on themselves.
Prosecutors claim Muir murdered Pamela at her home on The Crescent, Chester-le-Street, County Durham, in March.
She was missing for almost two months before her body was discovered buried on the south Pennines near Muir’s home town of Halifax.
Prosecutors claim Muir transported her body in his car 120 miles to the moors where she was found.
Muir, 50, of Calder Terrace, Halifax, denies murder.
The trial continues.
