Police say they are preparing to shelve the investigation into the murder of Suzy Lamplugh, 40 years after her disappearance in 1986, following what they describe as one final appeal for information. Multiple reports say officers are releasing or referencing a new image of Lamplugh as part of the renewed effort to prompt witnesses or people with relevant knowledge to come forward. The outlets describe the step of moving to shelve the case as the culmination of a long-running investigation into what happened to Lamplugh and where her body may be located. Police are asking members of the public to contact investigators with any details that could help clarify the circumstances of her death or assist with locating remains. Both sources frame the decision as ending the investigation’s active phase while still allowing a final opportunity for information that may improve understanding of the case or contribute to resolving outstanding questions. The family’s continued search for answers is cited alongside the police appeal.
