Forty years after she vanished, the disappearance of estate agent Suzy Lamplugh continues to trouble Metropolitan Police officers, who are preparing to move the case to an inactive phase next year. Lamplugh, 25, disappeared on July 28, 1986, after leaving her Fulham office to meet a client, identified in her diary only as "Mr. Kipper." Her white Ford Fiesta was later found abandoned nearby, and she was declared presumed dead in 1993.

Detectives are particularly haunted by the fact that Lamplugh's body has never been found. Det Ch Insp Teresa Foster, the senior investigating officer, believes Lamplugh may have been targeted by a stalker. She suggested that Lamplugh might have been placed in the office window to attract customers due to her perceived attractiveness, and that a predator may have lured her into a false meeting.

This theory aligns with the work of Lamplugh's parents, who established the Suzy Lamplugh Trust to campaign on personal safety and operate the National Stalking Helpline. Foster expressed her wish to "bring Suzy home," emphasizing the ongoing impact of the unsolved nature of the case.

The investigation into Lamplugh's disappearance was one of the UK's largest missing persons operations. Uniquely, it remains the only Metropolitan Police case still managed using a 1980s card index system, maintained in the hope that a handwritten detail might one day be significant. In a year's time, the inquiry will transition to an "inactive phase," meaning that while new information will still be considered, the dedicated team will cease active work on the case.

John Cannan, identified as the prime suspect, died in prison in November 2024. He was serving a sentence for the 1987 murder of Shirley Banks. Although a file was sent to prosecutors in 2002, Cannan was never charged in connection with Lamplugh's disappearance, and no forensic evidence has linked him to the case.
