Police were responding to a report of shots fired Friday when they encountered the RV blaring a recorded warning that a bomb would detonate in 15 minutes, Metro Nashville Police Chief John Drake said. Police evacuated nearby buildings and called in the bomb squad. 

The RV exploded shortly afterward.

Some of the calls were about an audio message warning about the bomb. Others reported the blast itself.

Additional information has surfaced that police were given a tip about the suspect, Anthony Warner, over a year ago.

Warner’s girlfriend told them he was building bombs in his RV.
Police went to her home, but never talked to Warner.

Warner died in the explosion.

The motivation behind the bombing still eludes investigators.
