The Tennesseean uncovered a Metro Nashville Police Department report from April 2019 in which Warner's girlfriend, who has not been named, told police he "was building bombs in the RV trailer at his residence."
Police had been called to the girlfriend's Antioch, Tennessee, home after her lawyer, Raymond Throckmorton III, became concerned over comments she had made. Throckmorton had previously served as counsel for Warner in a civil matter but did not represent him in August of 2019. According to documents seen by The Tennesseean, he told officers at the time Warner "frequently talks about the military and bomb-making," and "knows what he is doing and is capable of making a bomb."
After speaking with Throckmorton and Warner's girlfriend, police stopped by Warner's Bakertown Lane home and observed an RV in his backyard. According to the report seen by The Tennessean, it was fenced off, and officers were unable to see into it. They did note that it was surrounded by "several security cameras and wires attached to a[n] alarm sign on the front door."
According to The New York Times, a report of the incident and an inquiry into Warner was forwarded to the FBI and the Defense Department. Both organizations reported that they had no records of Warner.
Authorities are still speculating about what motivated Warner, but David B. Rausch, the director of the Tennessee Bureau of Investigation, told "The TODAY Show" on Monday, "it does appear that the intent was more destruction than death."
Warner was the only casualty in the blast, though several people reported injuries.
Rausch insisted that Warner had not previously been under investigation by the bureau.
"He was not on our radar," he told "TODAY." "He was not someone that was identified as a person of interest for the bureau. So we were not familiar with this individual until this incident."
"It's pretty obvious to me that somebody didn't do what they were supposed to do," Throckmorton told News Channel 5.
The bomb's explosion was captured in police bodycam footage early on Christmas morning by several officers who had been called to the scene.
"It kind of looked like a big prop from a movie scene, all the glass breaking at once," Officer Amanda Topping said at a press conference on Sunday.
The RV blast took place outside of an AT&T facility and caused damage to more than 40 buildings.
