CHRISTCHURCH, NEW ZEALAND: The man accused of the New Zealand mosque attacks smirked as his lawyer entered not guilty pleas to terrorism, murder and attempted murder charges Friday 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

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. It wasn’t immediately clear if the man had been arrested.

Janna Ezat wore a shirt that she’d designed which featured an image of her son Hussein Al-Umari, who was killed in the attacks. She said the court hearing had made her angry.

“Before I was OK and calm and believe in this life my son died and he is in a good place,” she said. “But when I saw the terrorist, he was just, he’s nothing. Just sitting like that. Pretending that he’s innocent and nothing is wrong.”

“It’s not easy to lose your child. Not only my child but 50 people,” Ezat said. “It’s unfair. It’s unfair. And he was laughing.”

Abdul Aziz, who is considered a hero for confronting the gunman at the Linwood mosque, said he wouldn’t say the suspect’s name.

“He’s a coward. And behind the cell, he’s laughing,” Aziz said. “He should have laughed when I faced him. Then I would see how he laughed. He run like a dog. He run like a chicken.”

In the March 15 attacks during Friday prayers, 42 worshippers were killed at the Al Noor mosque and seven were killed at the Linwood mosque. Two more people died later at the Christchurch Hospital.

The shooter live-streamed much of the attack on Facebook.

Tarrant had earlier published a 74-page manifesto espousing a white supremacist philosophy and detailing his plans to attack the mosques.

New Zealand’s Prime Minister Jacinda Ardern has vowed never to say the accused man’s name. Last month she helped lead a global pledge named the “Christchurch Call,” aimed at boosting efforts to keep internet platforms from being used to spread hate, organize extremist groups and broadcast attacks.
