Nashville explosion: Anthony Warner died in explosion, was 'bomber,' authorities say

Anthony Q. Warner, 63, has been identified as the "bomber" in the Christmas day explosion in Nashville by U.S. Attorney Don Cochran.

Cochran announced the update to the investigation in a Sunday afternoon news conference.

"Anthony Warner is the bomber. He was present when the bomb went off, and he perished in the bombing," Cochran said.

DNA found at the scene was matched to samples taken at another location searched by investigators, TBI Director David Rausch said Sunday. The TBI was involved in testing the evidence.
