Threatening message left for former Perth College chaplain on pornography charge Pictured is Matthew David O'Meara, the former Perth Colleage chaplain who is alleged to have been in possession of child pornography. A THREATENING voicemail left on the mobile phone of a former Perth College chaplain on trial for child pornography possession has been played in the District Court today. Matthew David O'Meara is on trial over four counts of possessing child pornography after thumb drives were found with photos of young girls on them at the school in August 2010. Andrew McCarthy was receiving counselling from Mr O'Meara during his marriage breakdown to a Perth College teacher and on Wednesday he told the court he saw a USB in the chaplain's laptop at the time. On January 5 this year, Mr O'Meara received a threatening phone call on his mobile phone. His lawyer Laurie Levy asked Mr McCarthy yesterday if he had anything to do with the call. Mr McCarthy denied any involvement. Today, case officer Detective Sergeant Sean Bell said when the message was forwarded to him to investigate, Mr O'Meara was "adamant it was from Andrew McCarthy." The recording was played in court this afternoon. In it, a man is heard saying, "oi c***, go witness against f***ing (inaudible) and see what happens." Sgt Bell said he had ruled out the call coming from Mr McCarthy or any other witnesses involved in the District Court trial. The message was played as part of the police evidence, which started today. During the evidence, Sgt Bell said that the seized thumb drives were not tested for fingerprints or DNA because the procedures damaged the USBs and did not always produce results. Mr Levy put it to Sgt Bell that since the issue of forensic evidence was brought up in the first trial, such tests should have been conducted. Sgt Bell said there still was no reason to do the forensic tests.
