Suspect Behind Nashville Bombing Not on Police Radar VOA News U.S. investigators say the man behind Nashville's Christmas Day bombing was "not on our radar" as they continued to work to determine a motive in Friday's explosion that injured three people. "He was not someone that was identified as a person of interest for the bureau, and so we were not familiar with this individual until '¦ this incident," said David Rausch, director of the Tennessee Bureau of Investigation, while speaking to reporters via a Zoom conference. Authorities on Sunday identified 63-year-old Anthony Quinn Warner as the man who blew up a motor home at dawn in a neighborhood of Tennessee's southern city of Nashville, killing himself. The blast damaged dozens of buildings and disrupted telecommunications systems in the neighborhood, which is filled with country music bars and restaurants. Investigators used DNA and other evidence such as locating the vehicle identification number from the motor home and tips from the public to link Warner to the explosion. Rausch said on Monday that Warner's mother was cooperating with the investigation but that the motive for the explosion was still not clear. He said Warner's only arrest was for a 1978 marijuana-related charge. .
