A judge yesterday halted a murder trial for the second time after two jurors requested to be exempted from service because of forthcoming exams. Mr Justice Gareth Lugar-Mawson was furious the requests were made after the seven-member jury had been empanelled and given directions yesterday. 'I am not cross about the request,' he said 'What I am furious about is this letter was not handed in when it should have been.' The judge said he could not put the trial at risk by forcing any juror to continue and again formally discharged the panel. A third panel will be formed today for the trial of Chukwuemeka Kweli Emeka, 25, accused of murdering his domestic helper and ex-girlfriend, Glenda Giron Lorio. The two jurors who were excused submitted written requests for exemption during a break after the jury was empanelled. The prosecution was about to open its case. The pair said they were due to take examinations, but they had not informed the court of this when they were sworn in after their names were drawn. Defence barrister Peter Lavac told the Court of First Instance that Emeka was frustrated and angry about the matter. Prosecutor Peter Callaghan said he was as anxious as the defendant. Mr Justice Lugar-Mawson said if jurors wished to be exempt from service, they had to write to the Registrar of the High Court or make an application to the trial judge before they were sworn in. 'The defendant is quite right to expect a fair and an expeditious trial. He has not yet received that,' the judge said. The trial hit its first hurdle on Friday after a juror fell asleep during the testimony of a prosecution witness. Mr Justice Lugar-Mawson told that jury it was being discharged for 'very good legal reasons'. The prosecution says Lorio, 31, allegedly beaten to death by Emeka, might still have been alive when she was stuffed through a manhole into a sludge-filled drain. Police found her body in the drain at the former British Military Hospital in Yau Ma Tei on May 23 last year. It has been alleged that Lorio wanted to end the relationship with the defendant because of physical and verbal abuse. She went to live in the former hospital, where the Philippines Consulate operates the Filipino Workers Resource Centre for domestic helpers involved in disputes with employers.
