Coniston massacre
Brooks was killed on or about 7 August 1928, and his body was partly buried in a rabbit hole. No eyewitnesses to the actual murder were ever identified, and there are conflicting accounts of the discovery of the body and subsequent events.

It was claimed by Royal Ulster Constabulary (RUC) Special Patrol Group (SPG) officer John Weir, that the UVF killers were Robin Jackson (who was also allegedly involved in the 1974 Dublin car bombings as well as a series of sectarian killings), Robert McConnell, and Harris Boyle. The men, including Weir, were all members of the Glenanne gang, which was made up of rogue elements of the RUC, Ulster Defence Regiment, regular British Army, and the UVF Mid-Ulster Brigade. These allegations were published in the 2003 Barron Report, which was the findings of an official investigation of the bombings by Irish Supreme Court Justice Henry Barron. In the same report, Weir claimed that he had received information from an informer that British Army captain Robert Nairac was also involved in Green's killing. The 1993 Yorkshire Television documentary "The Hidden Hand: The Forgotten Massacre" states that Robin Jackson and his UVF comrades were controlled by Nairac, who was attached to 14th Intelligence Company. Secret Intelligence Service operative Captain Fred Holroyd also asserted that Nairac had executed Green, who was, according to Holroyd, commander of the Provisional Battalion of North Armagh. Captain Holroyd claimed that Nairac boasted about the killing and had shown him a colour polaroid photograph of Green's corpse taken after the killing. Holroyd also told the Garda Síochána that he had received a photograph of Green some months prior to his killing. Holroyd enlarged the photograph and had it distributed. He believed from that time until Green's death, 4 Field Survey Troop, one of the three sub-units of the 14th Intelligence Company led by Captains Nairac and Tony Ball, had Green placed under surveillance. Nairac's claim has been discounted by two Garda investigations which revealed that the polaroid was one of a series taken of Green's body by a Garda officer the morning following his fatal shooting.
