A native of Kerry and former Special Branch detective, O’Sullivan spent 32 years serving in the Garda Síochána, primarily based in Cork. ‘Veil of Silence: How The Irish State Covered Up an IRA Murder and Framed a Garda Whistleblower’ recounts the 1985 murder of Garda informer John Corcoran, a father of eight, who was killed by the IRA in a case that remains unsolved. For the first time, O’Sullivan – Corcoran’s Special Branch handler – recounts the events leading up to the killing, including warnings he says were ignored by Garda Intelligence sources. In early 1984, JP O'Sullivan began warning Garda HQ in writing that any action against IRA members connected to Corcoran could blow his cover. ‘Veil of Silence: How The Irish State Covered Up an IRA Murder and Framed a Garda Whistleblower’ is published by Merrion Press.
