The Moors murders were a series of child killings committed by Ian Brady and Myra Hindley in and around Manchester, England, between July 1963 and October 1965. The five victims—Pauline Reade, John Kilbride, Keith Bennett, Lesley Ann Downey and Edward Evans—were aged between 10 and 17, and at least four of them were sexually assaulted. The bodies of two of the victims were discovered in 1965, in graves dug on Saddleworth Moor; a third grave was discovered there in 1987, more than twenty years after Brady and Hindley's trial. Bennett's body is also thought to be buried there, but despite repeated searches it remains undiscovered.
In England and Wales, life imprisonment is a sentence that lasts until the death of the prisoner, although in most cases the prisoner will be eligible for parole after a minimum term ("tariff") set by the judge. In exceptional cases a judge may impose a "whole life order", meaning that the offender is never considered for parole, although they may still be released on compassionate grounds at the discretion of the home secretary. Whole-life orders are usually imposed for aggravated murder, and can be imposed only where the offender was at least 21 years old at the time of the offences being committed.
