The jury in the trial of the Sligo man accused of murdering 14-year-old Melissa Mahon has heard that she took a pregnancy test which was positive before she went missing in September 2006. Two teenage girls have been giving evidence via video-link on day 12 of the trial of Ronald McManus at the Central Criminal Court. They said they were with Melissa Mahon in the toilets of a McDonalds when she took a pregnancy test and one said Melissa was "kind of happy, kind of delighted in a way". The 14-year-old went missing in Sligo and her remains were found on the shore of Lough Gill in February last year. The 44-year-old defendant, also known as Ronnie Dunbar, of Rathbraughan Park, Sligo, has pleaded not guilty to murdering the schoolgirl.
