Hugh Leonard Thompson Murphy, best known as Lenny Murphy (2 March 1952 – 16 November 1982), was an Ulster loyalist and sex abuse gang leader responsible for the murders of innocent Catholics.
Due to a lack of evidence to try him for the killings, which his followers had already received long sentences for, Murphy was released in 1982 and returned to the Shankill Road, where he embarked on a murder spree.
Details on Murphy's movements were apparently passed by Ulster loyalist paramilitaries to the Provisional IRA, who executed Murphy.
William Moore (who had confessed to detectives soon after being arrested) was portrayed in subsequent police accounts as having been in effective control of the Butchers gang during Murphy's incarceration.
However a 2017 book on the UVF asserted that John, an older brother of Murphy who escaped prosecution, had been directing the activities of the Butchers during that time.
