"Dalton Tyler, Roof’s roommate, told ABC News that Roof spoke of starting a civil war and that he advocated racial separatism. “He was big into segregation and other stuff. He said he wanted to start a civil war. He said he was going to do something like that and then kill himself,” Tyler said.
Scott Roof, who identified himself as Dylann Roof’s cousin, told me over the telephone that “Dylann was normal until he started listening to that white power music stuff.” He also claimed that “he kind of went over the edge when a girl he liked starting dating a black guy two years back.”
This scenario recalls a manifesto written by Elliot Rodger, who on May 23, 2014 gunned down six people in Isla Vista, California: “How could an inferior, ugly black boy be able to get a white girl and not me?”
“Dylann liked her,” Scott Roof said. “The black guy got her. He changed. I don’t know if we would be here if not …” Roof then abruptly hung up the phone."
