The suspect in the massacre at a historic black South Carolina church has been arrested as the nation mourns the killing of nine victims. Twenty-one-year-old Dylann Roof was detained Thursday morning during a traffic stop in North Carolina. A friend of Roof’s said he wanted to start a new civil war. In a photo posted on Facebook, Dylann Roof is seen wearing a black jacket that prominently features the flags of Rhodesia, now Zimbabwe, and apartheid-era South Africa from when the two African countries were ruled by the white minority. Another photo appears to show Roof posing in front of a car with a front plate that reads “Confederate States of America.”

Sylvia Johnson: “I spoke with one of the survivors, and she said that he had reloaded five different times. And her son was trying to talk him out of doing that act of killing people. And he just said, 'I have to do it.' He said, 'You rape our women, and you're taking over our country. And you have to go.’”

The Department of Justice is investigating Wednesday’s attack as a hate crime, motivated by racism or other prejudice.
