In September 2009 it was revealed that a Police Ombudsman's report on the killings was to be published on 15 September. At the same time, some details of the report were made known. Police sources said the report would expose the role of four RUC informers in "ordering or organising" the attack. The report was also said to highlight a series of major failings in the police investigation – including that not enough effort was made to identify those responsible, that police failed to speak to people of interest, that key evidence was destroyed and that there was poor record management. Shortly after these revelations, the Ombudsman postponed publication of the report as "new evidence" had emerged.
