NASHVILLE, Tenn. (WKRN) — Metro Nashville Police Chief John Drake held a news conference Wednesday afternoon to provide an update on the downtown Nashville bombing.  

On Tuesday, News 2 obtained documents showing Metro police received a complaint last year that Anthony Warner, the man accused of detonating a bomb in downtown Nashville early Christmas morning, was making bombs in an RV at his Antioch home.

Chief Drake explained MNPD’s response after Warner’s girlfriend told police he was making bombs in his RV. Ultimately, police did not have a search warrant and did not search the RV. An attorney representing Warner told police he would not let his client allow police to search his property.

“I believe the officers did everything they could legally. Maybe we could’ve followed up more, hindsight is 2020,” Chief Drake said.

Chief Drake said he would put a plan in place to work more closely with the FBI.

“We don’t have an officer on the Joint Terrorism Task Force, which is connected to the FBI. And so that was brought to my knowledge as well, so we’ll start that, put an officer on that team to eliminate any gaps.”

Chief Drake said MNPD would continue to investigate emphasized multiple agencies ran criminal history checks on Warner and did not find any violations. The only known criminal history for Warner was a 1978 drug charge.

“As we find out what gaps there may have been, what we could have done differently, we’ll address it.”

Earlier Wednesday, News 2 obtained the frantic 911 calls from Christmas morning reporting sounds of gunshots followed by the explosion from an RV. 

Since the bombing, ABC News confirms federal investigators are looking into whether Anthony Warner may have been motivated, at least in part, by “paranoia over 5G technology,” but that they also found writings that contained ramblings about assorted conspiracy theories, including the idea of shape-shifting reptilian creatures that appear in human form and attempt world domination. 

The FBI is in Nashville providing victim assistance and crisis intervention resources. As of Tuesday night, the team had completed more than 220 needs assessments to determine what resources were needed.
