AKIPRESS.COM - A young white man suspected of killing 9 at The Emanuel African Methodist Episcopal Church was caught, the Associated Press said June 19.

Six women and three men were killed.

Dylann Storm Roof, 21, had complained that "blacks were taking over the world" and that "someone needed to do something about it for the white race," according to a friend who alerted the FBI. He was arrested with his gun after an all-night manhunt, authorities said.

President Barack Obama called the tragedy yet another example of damage wreaked on America by guns.

Surveillance video showed the gunman entering the church Wednesday night, and Charleston County Coroner Rae Wilson said the gunman initially didn't appear threatening.

"The suspect entered the group and was accepted by them, as they believed that he wanted to join them in this Bible study," she said. Then, "he became very aggressive and violent."

Roof was arrested without incident Thursday in Shelby, North Carolina, after a motorist spotted him and tipped police. His previous record includes misdemeanor drug and trespassing charges.

U.S. Attorney General Loretta Lynch said the attack would be investigated as a hate crime.
