The gunman behind the massacre of 49 people in two New Zealand mosques flashed a white power sign during a brief court appearance on Saturday, but he was not on any terrorist watch-list and appeared to have no criminal history.
Tarrant, 28, grew up in the small town of Grafton in northern New South Wales, where he graduated high school before earning some fitness qualifications and going on to find work at a local gym in 2009.
The gym’s owner, Tracey Gray, described him as a hard-working trainer but said he appeared to have been changed by his travels in Europe and Asia – which social media posts suggested included trips as far afield as Pakistan and North Korea.
“I think something must have changed in him during the years he spent travelling overseas,” Gray told national broadcaster ABC.
“Somewhere along the lines, experiences or a group have got a hold of him,” she said.
Gray’s speculation was backed up by a rambling, hate-filled, manifesto Tarrant posted to social media ahead of the Christchurch killings.
In the 74-page screed, he says he first began considering an attack in April and May of 2017 while travelling in France and elsewhere in Western Europe.
He mentions being shocked at the “invasion” of French cities by immigrants and his “despair” at the French presidential vote that year which saw pro-European centrist Emmanuel Macron defeat his far-right opponent Marine Le Pen.
In a brief biographical sketch included in his manifesto, Tarrant describes himself as “just a ordinary white man … born in Australia to a working class, low income family”.
His childhood was “regular” and, he insisted, issue-free. He “barely” achieved a passing grade in school and had no interest in pursuing higher education.
According to media reports, his father died of cancer in 2010 and gym owner Gray said she believed he had a mother and sister still living in Grafton.
Tarrant left the gym in 2011 and his travels, he says, were funded by money he made investing in Bitconnect – an open source cryptocurrency that collapsed in early 2018 amid charges it was a glorified Ponzi scheme.
Two modified semi-automatic weapons – reportedly AR-15s – two shotguns and a lever-action gun were used in Friday’s deadly rampage, and photos of the weaponry with distinctive writing on them were posted on social media days before.
Scrawled in English and several Eastern European languages were the names of numerous historical military figures – many of them Europeans involved in fighting the Ottoman forces in the 15th and 16th centuries. A few took part in the Crusades, centuries earlier.
His manifesto said he took “inspiration” from other right-wing extremists including racist Norwegian killer Anders Behring Breivik, who murdered 77 people in Norway in 2011 motivated by his hatred of multiculturalism.
Tarrant described Oswald Mosley, a notorious British fascist leader and anti-Semite from the 1930s, as “the person from history closest to my own beliefs”.
