A website featuring photos and a racist manifesto purportedly linked to Charleston church shooting suspect Dylann Roof surfaced on Saturday.

Authorities are currently trying to authenticate the website, lastrhodesian.com, which contains dozens of photos of a man who appears to be Roof holding confederate flags and wearing racist symbols. One photo shows him burning an American flag. Another shows a .45 caliber handgun, a gun similar to the one allegedly used in the church shootings.

There is also a lengthy manifesto in which the author says he was awakened by the Trayvon Martin shooting and that “it was obvious (George) Zimmerman was in the right.” It is filled with derogatory rants against several ethnic groups, including blacks, Jews, Hispanics, and east Asians. As for patriotism, the author says “I hate the sight of the American flag.”

Towards the end, in a section titled “An Explanation”, the author writes that he “chose Charleston because it is the most historic city in my state, and at one time had the highest ratio of blacks to whites in the country.”

The Associated Press reports that the FBI is aware of the website and is looking into its authenticity. But the writings are in line with what he told his friends and what he said before allegedly opening fire inside Emanuel AME Church on Wednesday night.

Internet records show that the website was registered on Feb. 9th via a Russian registry service, a common tactic used by those to obscure personal details or hide who is behind any particular website.
