One woman was killed and seven other people were hurt after a suspect identified as a Sudanese immigrant opened fire at a Tennessee church Sunday, police said, as federal officials told Fox News the FBI will initiate a civil rights investigation into the shooting. The suspect, 25-year-old Emanuel Kidega Samson, immigrated from Sudan two decades ago, police said. He's suspected of bringing two pistols and a mask to the predominantly white Burnette Chapel Church of Christ in Antioch, southeast of Nashville, before opening fire just after 11 a.m.
