According to the Barron Report ( 2003 ) , one of the pistols ( a Luger ) used in Green 's killing was linked six months later to the Miami Showband killings , which left three band members dead . Both Robin Jackson and Robert Nairac were allegedly behind that attack , while Harris Boyle was blown up after the bomb he and Wesley Somerville ( another UVF and Glenanne gang member ) had placed in the band 's minibus had gone off prematurely . Martin Dillon , in his book '' The Dirty War '' , claims that Nairac was not involved in Green 's killing , nor the Miami Showband attack . In his 2015 biography of Nairac , retired diplomat Alistair Kerr produced evidence that clears Nairac of involvement in both the Green killing and Miami Showband ambush
