The suspect allegedly behind the Christmas Day bombing in downtown Nashville has been identified as 63-year-old Anthony Quinn Warner, two law enforcement sources confirmed to Fox News.

Authorities believe Warner owned the RV that exploded in downtown Nashville early Friday, sources said. He also is believed to be deceased from the blast.

Warner was believed to have lived at the home in Antioch, Tenn., searched for several hours Saturday by the FBI and several other law enforcement agencies. The home address on Google Earth shows the same RV parked in different places on the property dating back several years.

It appears to be a “lone wolf” situation, but the motive remains under investigation. Authorities do not believe the city of Nashville is in danger.

Police said the RV sounded warnings to evacuate and a 15-minute countdown to clear the area. The voice of the woman on the recording is believed to be a robotic, computerized voice, the sources said.

The RV also blasted a song before it detonated, which was identified by law enforcement as “Downtown” by Petula Clark.
