CHRISTCHURCH, New Zealand • A New Zealand judge on Friday ordered that the man accused of killing 50 people at two Christchurch mosques undergo two mental health assessments to determine if he’s fit to stand trial.

High Court judge Cameron Mander made the order during a hearing in which 28-year-old Australian Brenton Harrison Tarrant appeared via video link from a small room at the maximum security Paremoremo prison in Auckland.

Tarrant was wearing handcuffs and a gray-colored sweater when he appeared on a large screen inside the Christchurch courtroom, which was packed with family members and victims of the shooting, some in wheelchairs and hospital gowns and still recovering from gunshot wounds.

Tarrant had stubble and close-cropped hair. He showed no emotion during the hearing. At times he looked around the room or cocked his head, seemingly to better hear what was being said. The judge explained that from his end, Tarrant could see the judge and lawyers but not those in the public gallery.

Tarrant spoke only once to confirm to the judge he was seated, although his voice didn’t come through because the sound was muted. It wasn’t immediately clear if his link had been deliberately or inadvertently muted.

Mander said nothing should be read into his order for the mental health assessments, as it was a normal step in such a case. Lawyers said it could take two or three months to complete.

The courtroom was filled with more than two dozen reporters and about 60 members of the public. A court registrar greeted people in Arabic and English as the hearing got underway. Some of those watching got emotional and wept.

The judge said Tarrant was charged with 50 counts of murder and 39 counts of attempted murder. Police initially filed a single, representative murder charge before filing the additional charges this week.
