CHRISTCHURCH, New Zealand (AP) — The man accused of the New Zealand mosque attacks smirked as his lawyer entered not guilty pleas to terrorism, murder and attempted murder charges today before a judge who set his trial for next May.

The courtroom was filled with 80 survivors and family members of the 51 who were slain, while about another 60 watched the hearing on video in an overflow room at the Christchurch High Court. Four cultural advisers and other staff were assigned to help the victims and family members understand the proceedings and the next steps in the case.

A man who addressed the survivors said they had been praying during the holy month of Ramadan and that the Muslim community would help and support each other during the coming weeks and months.

Brenton Tarrant, the 28-year-old Australian accused of the attacks, appeared at the hearing via video link from a small room at the maximum security prison in Auckland where he’s being held. The link was muted and he didn’t attempt to speak.

Other than smirking a couple of times, Tarrant showed little emotion during the hearing. When Judge Cameron Mander asked if he could hear and see what was going on in the courtroom, Tarrant nodded. At times he looked around the room and stretched his neck.

The judge did not allow cameras or video in the courtroom although did approve a sketch artist commissioned by The Associated Press.

Tarrant has been charged with 51 counts of murder, 40 counts of attempted murder and one terrorism charge in relation to the March 15 shootings.

Mander said the findings of two mental-health assessments showed Tarrant had no issues related to his ability to enter pleas and stand trial. The assessments are standard in murder cases.

The judge scheduled a six-week trial to begin May 4. Tarrant will remain in custody ahead of his next hearing in mid-August.

Outside the court, police and court security staff escorted a man away after he got into an argument with survivors and family members, who later said the man was saying things supportive of white supremacist ideology.

Police said they arrested a 33-year-old man and charged him with disorderly behavior.
