With permission from the current head of the IRA, an individual known only as "Witness O" testified at this inquest on 22 March, naming four men (one of whom was Mick Murray) as responsible for the bombings. He also testified as to his belief that security services had been given adequate time to evacuate both pubs. On 5 April, the jury of 11 found that a botched advance IRA telephone warning contributed to or caused the 21 deaths and that there had been no error or omission in the police response to the given warning call which might have limited the loss of life.
