Investigators find human remains at Nashville Christmas explosion blast site hinting at possible ‘suicide bombing’

Federal prosecutors and Nashville police are following more than 500 leads and tips in their investigation into an explosion that rocked downtown Nashville, Tennessee on Christmas morning.

The explosion left at least three injured and caused a massive telephone, internet outage.

Federal agents searched the home of a possible person of interest in the Nashville suburb of Antioch.

Before the explosion witnesses reportedly heard a recorded voice from the RV, saying, “Evacuate now. There is a bomb. A bomb is in this vehicle and will explode.”

The voice then started a 15-minute countdown and the RV played music.

Officers, responding to an early morning call on Friday for shots fired, encountered the RV as the recording played, police said. The officers began evacuating nearby buildings.

The RV exploded around 6:30 a.m. CT, according to authorities.

At least 40 buildings and businesses were damaged.

Investigators have supposedly found tissue samples found at the scene were human remains, AP reported.

US media reported that investigators believe that the blast was likely the result of a suicide bombing.

Governor Bill Lee after visiting the site of the explosion said that the “damage is shocking and it is a miracle that no residents were killed.”
