Witness Andrew McCarthy 'remembered seeing' USB in Matthew David OMeara's laptop A MAN who was receiving counselling from a Perth College chaplain in 2010 has told a District Court child pornography trial how he saw a USB in the reverends laptop at the time. Matthew David O'Meara is in trial over four counts of possessing child pornography after thumb drives were found with images of a young girl on them at the school in August 2010. Today, while Andrew McCarthy gave evidence, the jury heard how the matter had already gone to trial last year. Mr McCarthy was seeing Mr O'Meara in 2010 for counselling while his marriage to a Perth College teacher was breaking down. It was during last year's trial that Mr McCarthy came forward, telling the court today that he approached prosecutors after hearing Mr O'Meara's testimony. He said after the October 2012 trial he had told friends that he remembered seeing a USB in Mr O'Meara's lap top. "It stuck out like a sore thumb," he said. Mr O'Meara's lawyer Laurie Levy said earlier this year, his client had received a telephone threat about giving evidence in the latest trial. Mr Levy asked Mr McCarthy if it was him or if he asked someone to make the call. Mr McCarthy said he knew about the threats, but did not make them.
