He announced that his mass killed over social media and filmed it live on the internet. He shared a 74-sided online manifesto that zipped sarcastic jokes about popular culture, repeatedly known internet memes and striving to mint new ones.
He presented his explanation in a "Q. and A." format, as in an interview, besides imagining the reactions.
"I'm sure journalists will love it" he wrote after answering "yes" to his own question "where are you fascist?"
The man accused him of killing 49 people on Friday in a shootout at two mosques in Christchurch, New Zealand, identified in court papers on Saturday as Brenton Harrison Tarrant, is a 28-year-old bodybuilder and personal trainer from the small town of Grafton, Australia. He is the son of a local junkie who made a hobby to compete in Ironman triathlons.
But after his father, in 2010, the life of the suspect took him in an unexpected direction. He invested in cryptocurrency, completed his gym job and took an idiosyncratic tour through North Korea, Pakistan, Eastern Europe, France and elsewhere.
And his travels – apparently solo – killed him deeply into the online world of white nationalist message cards.
Mr. Tarrant now appears to have become the first accused mass murderer to conceive to kill himself as a meme; It seems that he was both inspired by social media and practiced it, hoping that his video, images and text would become viral.
"Terrorism is the propaganda of action and the terrorist is always as interested in his audience as his victim," said Reid Meloy, a forensic psychologist and consultant to the Federal Bureau of Investigation, paraphrasing Russian anarchist Mikhail Bakunin from the 19th century.
"But social media makes this vector much more powerful," says Dr. Meloy. "We are hosting the virus, and we are accelerating its spread."
The suspect's parents differed early in their childhood, according to his father's death in The Daily Examiner, Grafton. Mr Tarrant's mother was not mentioned in the death row, suggesting that she may have been deployed from her father.
According to the ram, his father competed in 75 triathlon races, including troubling Ironman triathlons in both Australia and Hawaii.
A woman of the same name as Mr Tarrant's sister played the drums in local rock bands, according to local news reports.
"Just an ordinary white man" from "a working class, low income family", Tarrant wrote in his manifesto. "I had regular childhood, without any major problems. I had little interest in the education at my school, barely achieved the approved course. I did not attend the university because I had no great interest in everything that was offered in the universities to study."  It is unclear how he developed an interest in cryptocurrency, but he wrote in his manifesto that his profits from investing in the Bitconnect crypto course enabled him to travel.
The Australian news on Friday published a photograph of him with a tour group near Samjiyon Grand Monument in North Korea. His manifesto also draws attention to visits to Poland, Ukraine, Iceland and Argentina.
References throughout his manifesto indicate that he was deeply immersed in white nationalist internet forums. He also seems to have developed a detailed interest in American politics.
To make his case for the effectiveness of memes, he pointed to a candidate in the 2016 Republican President's primary he apparently turned out to be boring: "No one is inspired by Jeb Bush."
"Where / are you a Donald Donald Trump? "Mr. Tarrant asked himself in the manifesto. "As a symbol of renewed white identity and common purpose? Sure. As a policy maker and leader? Dear God no."
He wrote that somehow his attack was specifically aimed at an American audience.
"I chose firearms for the impact it would have on social discourse, the extra media coverage they would give and affect what might have on the United States policy and thereby the world's political situation," he wrote.
He hoped "to create conflicts between the two ideologies of the United States on the possession of firearms to further the social, cultural, political and racial division," thus "to ensure the death of" the potpipe dream ".
He claimed that he was not the type to seek fame. "19659002]" I will soon be forgotten, "he added." As I do not care. After all, I am a private and mostly introverted person. "
Mr Tarrant is hardly the first accused murderer to take a cue from social media or enjoy his reaction.
In 2015, an armed robber in Roanoke, Va. Attempted to stream video about his killing of two local TVs Next year, a gunman who attacked an Orlando, Fla., night club paused between shots to post on his own Facebook page.
But mass murderers often try to invent themselves to outdo their predecessors, among others. otherwise through the use of the media, Mr. Meloy, the forensic psychologist, noted, and Mr Tarrant seems to have broken new ground in his self-conscious efforts to surf the webfandom's waves.
He opened his video on his death by reciting the slogan of preteen and youth fans of a wildly popular YouTube channel devoted largely to humor and video games (although sometimes affected by allegations of anti-Semitic or anti-Muslim b igotry): "Remember, lads, subscribe to PewDiePie."
creator of PewDiePie, Felix Kjellberg, published on Twitter that he was "sickly" by the association, and in the process it inevitably helped to publish death.
"Have you read violence and extremism through video games, music, literature, cine mom?" Mr Tarrant asked himself and responded with sarcasm: "Yes. Spyro dragon 3 taught me non-nationalism. Fortnite trained me to be a killer and Sparkling on my enemies. "
Spyro the Dragon and Fortnite are both popular video games and the" floss "is a dance movement popular with class schools that characters in Fortnite sometimes perform.
He even urged other white nationalists to be creative.
"Painting, writing, singing, dancing, reciting poetry. Hell, even mother," Tarrant wrote. "Memes have done more for the non-nationalist movement than any manifest."
He later recommended "pointed humor and memes" and appealing "to today's anger and black comic nature".
For his own account, during a month's period during his travels in Europe during the spring of 2017, [radical] was radically liberalized. .
One month later, on May 7, the French presidential candidate Marine le Pen – whom Tarrant termed milquetoast because she demanded the expulsion of only illegal immigrants – was defeated by the liberal president Emmanuel Macron.
"I found my feelings swinging between raging anger and suffocating despair at the alien invasion of France," he wrote, referring to the immigrants he saw there.
His curren t-address is in Dunedin, New Zealand, according to court records. He wrote in his manifesto that he began planning an attack two years ago and settled on the mosques in Christchurch two months ago.
He originally wrote a much longer manifesto, which stretched to 240 pages, he wrote. But he seemed to have had other thoughts.
"In a moment of incredible self-criticism," he wrote, "I removed the whole work and started again, two weeks before the attack itself".
He wrote that he intended to survive the attack. But as he wrote, he seemed to be wrestling with the likelihood that he would perish.
His questions to himself alternate between the present and the past, as if he is uncertain that he will live at his represented interview. 19659002] "I will see you in Valhalla," he wrote at the end.
