At some point over the Early May bank holiday weekend in 1998, William and Patricia Wycherley were shot and killed in their home in a suburb of Mansfield, England, by their daughter Susan and her husband, Christopher Edwards. The Edwards then buried the bodies in the garden behind the house and went on to use the Wycherleys' identities to commit various acts of fraud intended to fund their hobby of collecting expensive Hollywood memorabilia.
The crime went undiscovered until 2012, when Christopher contacted his stepmother to ask for money and confessed. At this point the Edwards were living in Lille, France, having moved there when the UK's Department for Work and Pensions requested an interview with William Wycherley to assess his needs, as he would have been approaching his 100th birthday. They eventually agreed to surrender themselves to police at St Pancras railway station in October 2013 after travelling back to the UK.
The couple were found guilty of murder in June 2014 and were sentenced to life imprisonment with a minimum term of 25 years. The case was the basis for a 2021 docudrama miniseries titled Landscapers.
