Sydney - The family of the Australian man arrested for the slaughter of 50 Muslim worshippers in New Zealand said Sunday they were stunned and "shattered" by his horrific deed.
"We're all gob-smacked, we don't know what to think," Brenton Tarrant's grandmother, Marie Fitzgerald, told Australia's Channel Nine network.
"It's just so much... to take in that somebody in our family could do anything like this," Fitzgerald said from her home in New South Wales state.
Tarrant grew up in the small town of Grafton and showed no signs he would later become enthralled with white nationalist ideology while travelling in Europe and then turn that hatred into violence.
"It's only since he travelled overseas I think that the boy has changed, completely," she said, adding that as a teen, Tarrant was interested mainly in computer games.
