Suspected Christchurch terrorist Bernton Tarrant apparently vowed to kill Muslims a day before the attack - and was praised after the heinous act by his followers on social media.
An anonymous user thought to be Tarrant wrote on notorious right-wing blogging website 8Chan on Thursday: 'I will carry out an attack against the invaders, and will even live stream the attack via Facebook.'
He shared a link to a video so his supporters in other timezones could watch the massacre and said: 'By the time you read this I should be going live.'
In a reference to the Viking version of heaven, Tarrant added: 'If I don't survive the attack, goodbye, godbless and I will see you in Valhalla'.
Tarrant also posted images of his ammunition and weapons on social media before his attack.
But he was not picked up by police because he was not on the terror watchlist.

Prime Minister Jacind Ardern confirmed in a press conference: 'Those, as far as I am advised, currently in custody were not on security watchlist.
'It is a question if they were known from a security perspective. They were not on any active watchlist.'
Tarrant also told his followers to read his 73-page manifesto that he posted online so that he could be remembered.
The post was written under an anonymous name but was widely circulated on social media by Tarrant's fans.
Once the attack began, fans cheered him with statements such as 'HEIL BRENTON TARRANT.'
After the news broke on social media and television, his followers began making threads about the attack and praising him for his role in the massacre.
