The trial of a 37-year-old man accused of murdering his partner Jean Quigley in the North last year has been adjourned until tomorrow. Stephen Cahoon, of Harvey Street in Derry, has pleaded not guilty to murdering the 30-year-old mother-of-four at her home in Cornshell Fields, Derry, in July 2008. The trial was due to get underway this morning, but the jury members were sent away for over half an hour and, when they returned, they were told that, in light of the complexity of the case, it was to be postponed until tomorrow. Mr Justice Patrick McCarthy told them there were a very large number of witnesses and both sides were endeavouring to reduce the complication. Jean Quigley, who was two months pregnant at the time, was beaten to death at her home on July 26th last year. Her partner, Stephen Cahoon, was arrested in Donegal town in August 2008 and chose to have his trial in the Republic instead of the North.
