A 20-year-old woman has pleaded not guilty at the Central Criminal Court to the murder of a woman in Laytown, Co Meath.
Emma McLoughlin, 19, was stabbed to death outside a supermarket on 2 June last year.
Kelly Noble from Seaview in Laytown has also denied a second charge of unlawfully producing a knife in the course of a dispute or a fight, in a manner likely to inflict injury.
A jury has been sworn in to hear the case, which is due to begin on Thursday and could last up to three weeks.
