Searches of a back garden in connection with the murder of estate agent Suzy Lamplugh have continued for a fourth day.
Tarpaulins remain in place and it's understood a shed was lifted today and a garage dismantled.
Miss Lamplugh was declared dead, presumed murdered, after going missing aged 25 in 1986, having left her west London offices to meet a mystery client known only as Mr Kipper.
Specialist forensics teams have been focusing their activity on the rear garden of a semi-detached house in Sutton Coldfield, West Midlands, which once belonged to the mother of prime suspect John Cannan.
The Met Police have told ITV News Central that work will continue at least until tomorrow, while on the ground it's thought it could continue into next week.
