Police have called off their search of a property as part of the latest investigation into the disappearance 32 years ago of estate agent Suzy Lamplugh, but have vowed to keep the case open.
No evidence was recovered from the garden of the house which belonged to the mother of chief suspect John Cannan.
Since October 29, officers from the Metropolitan and West Midlands forces have been on the site of the property in Sutton Coldfield.
Det Chief Supt Richard Wood said: “Suzy was a young woman when she was reported missing on July 28, 1986.
“She is presumed dead and is believed to have been murdered. Her body has never been found and no one has ever been charged as part of the investigation.
“This has been a landmark case for the Met, both in terms of its scale and complexity, and because of the huge sense of tragedy of a young woman’s life being cut short and the uncertainty around what happened to Suzy.”
Paying tribute to the courage and strength of her family, he stressed: “The case remains open and the Met remains committed to bringing Suzy’s killer to justice. We will continue to assess any new information that comes in.”
Suzy vanished while on a viewing. Both her parents have since died, not knowing what became of her.
The case is a constant reminder to agency bosses to keep their own staff safe and have checking and alarm procedures in place.
