Nashville bombing motive proves elusive

Investigators are analyzing a computer and portable storage drive that belonged to 63-year-old Anthony Quinn Warner in an attempt to determine why he may have detonated a bomb in Nashville, Tenn., on Christmas morning. Warner is the prime suspect in the investigation and was the only person who died in the explosion outside an AT&T building that injured three people and knocked out power as far away as Kentucky.

What do we know about Warner? Police have said he wasn’t on the radar before the explosion. But he had recently given away a vehicle and transferred the title of his Antioch, Tenn., home of decades in exchange for no money, an official speaking on condition of anonymity told Associated Press.
