A website apparently giving a glimpse into the mind of Charleston massacre shooter Dylan Roof has surfaced on the internet.

The website – registered on the 9 February 2015 – is entitled The Last Rhodesian. It's only content is a 110MB compressed file containing photos, and a 2,500 word manifesto filled with racist diatribes.

In his manifesto, Roof writes about his hatred of black people beginning with the Trayvon Martin case which led him to visit white supremacists websites which wrote about Black-on-White crime.

In the rambling text, he describes how he was "never the same" after visiting the websites that detailed white Americans being killed by blacks, and which claim racial problems in Europe are worse, as it is the "homeland of White people".

Roof goes on to vent racist anger at Jewish people and Hispanics, while describing people from East Asia as potential "allies" of the white race.

After almost two thousand words explaining justifying what he is about to do, he concludes:

"I have no choice. I am not in the position to, alone, go into the ghetto and fight. I chose Charleston because it is most historic city in my state, and at one time had the highest ratio of blacks to Whites in the country. We have no skinheads, no real KKK, no one doing anything but talking on the internet. Well someone has to have the bravery to take it to the real world, and I guess that has to be me."

The homepage features an image of Russell Crowe from the Australian movie about a neo-Nazi group Romper Stomper, where he lies dying in a pool of blood.

At the bottom of the page there is also an option to download pictures of Roof in a number of poses including a number of him wearing the jacket with the flags of Rhodesia and Apartheid-era South Africa, and holding a gun.

Warning signs

This follows news that Roof allegedly told friends that he was "going to hurt a bunch of people" at a college in Charleston seven days before allegedly opening fire in a church and killing nine black worshippers.

Christon Scriven, a black friend of the 21-year-old, told the Washington Post he was so concerned by the outburst that he hid Roof's .45-caliber handgun in the air-conditioning vent of a mobile home.

Roof was given back his weapon days before the fatal shooting, after a girl living in the trailer said she wanted it out of the house.

Scriven describes Roof as an extremely unhappy person who drank heavily and moved around between his divorced parents' homes because he felt unloved, according Reuters.

"My reaction at the time was, 'You're just talking crazy,'" Scriven told the Post. "I don't think he's always there."
