Police investigating the 33-year mystery of estate agent Suzy Lamplugh's murder have begun further searches in Worcestershire following "new information".
Ms Lamplugh was declared dead in 1994, presumed to be murdered, after going missing aged 25 in 1986.
She had left her west London offices to meet a mystery client known only as Mr Kipper.
The Metropolitan Police said officers had commenced the searches in Pershore today, at a site near a meadow which was dug up in 2010.
The force said they received information about Ms Lamplugh's disappearance following publicity of the search of a property in Sutton Coldfield - which previously belonged to the prime suspect's mother - in November 2018.
Her murder is considered one of the most notorious cold cases in recent criminal history.
Here are the key events in the case to date:
July 28, 1986
Miss Lamplugh leaves her estate agency office in Fulham, west London, at 12.40pm to meet a client called Mr Kipper.
At 10pm, her white Ford Fiesta is discovered in Stevenage Road, Fulham. The doors are unlocked, the handbrake is off and the ignition keys are gone. Her purse, still containing £15, is in the pocket of the driver's door.
A massive police hunt is launched.
The Suzy Lamplugh Trust is set up by Suzy's parents, Paul and Diana Lamplugh, to tackle violence and support stalking victims.
With few leads, the police inquiry into the disappearance is closed. The file remains open.
John Cannan is jailed for life with a minimum of 35 years for the murder of newlywed Shirley Banks in Bristol. He is also sentenced for a rape and an attempted kidnap.
Miss Lamplugh is officially declared dead, presumed murdered.
