Investigators in Tennessee Blast Looking at Link to Suburban Nashville Home VOA News U.S. authorities are continuing to investigate the Christmas Day vehicle explosion in the southern city of Nashville, Tennessee, looking for clues in a home about 18 kilometers from the blast site. Investigators suspect a link to a resident of the duplex in the suburb of Antioch. They say the person might have blown himself up in the recreational vehicle that had been parked in an area filled with country music bars and restaurants. But authorities are running down hundreds of tips about the blast and have not reached any conclusions about the explosion, which they have described as an "intentional act" and "deliberate bomb." The Friday morning blast damaged dozens of buildings and sent three people to the hospital with what police said were noncritical injuries. Neighbors near the home said a light-colored recreational vehicle like the one that blew up had been parked in the backyard for several months. Authorities say they have not found any evidence so far that point to other possible conspirators or threats of other explosions. .
