NASHVILLE The man authorities believe was responsible for setting off a Christmas Day bomb that injured three people and damaged dozens of buildings in downtown Nashville told a neighbour days before the explosion that Nashville and the world is never going to forget me.

Rick Laude said he saw Anthony Quinn Warner standing at his mailbox on Dec. 21 and pulled over in his car to speak with him. After asking how Warners elderly mother was doing, Laude said he casually asked him, Is Santa going to bring you anything good for Christmas? Laude said Warner smiled and then said, Oh, yeah, Nashville and the world is never going to forget me.

Laude, 57, a commercial truck driver, said he didnt think much of the remark and thought Warner only meant that something good was going to happen for him. He said he was speechless later when he read that authorities had identified Warner as the suspected bomber.

Nothing about this guy raised any red flags, Laude said. He was just quiet.

THIS IS A BREAKING NEWS UPDATE. APs earlier story follows below.

With federal officials having identified the man believed to be behind Nashvilles Christmas Day bombing, authorities now turn to the monumental task of piecing together the motive behind the explosion that severely damaged dozens of downtown buildings and injured three people.

While officials on Sunday named Anthony Quinn Warner, 63, as the man behind the mysterious explosion in which he was killed, the motive has remained elusive.

We hope to get an answer. Sometimes, its just not possible, David Rausch, the director of the Tennessee Bureau of Investigation said in a Monday interview on NBCs Today show. The best way to find motive is to talk to the individual. We will not be able to do that in this case.

In just a few days, hundreds of tips and leads have been submitted to law enforcement agencies. Yet thus far, officials have not provided information on what possibly drove Warner to set off the explosion. According to officials, he had not been on the radar before Christmas. A TBI records report released Monday showed that Warners only arrest was for a 1978 marijuana-related charge.

It does appear that the intent was more destruction than death but again thats all still speculation at this point as we continue in our investigation with all our partners, Rausch added.

Furthermore, officials have not provided insight into why Warner selected the particular location for the bombing, which damaged an AT&T building and continued to wreak havoc on cellphone service and police and hospital communications in several Southern states as the company worked to restore service.

Forensic analysts were reviewing evidence collected from the blast site to try to identify the components of the explosives as well as information from the U.S. Bomb Data Center for intelligence and investigative leads, according to a law enforcement official who said investigators were examining Warners digital footprint and financial history, as well as a recent deed transfer of a suburban Nashville home they searched.

The official, who was not authorized to discuss an ongoing investigation and spoke to the AP on condition of anonymity, said federal agents were examining a number of potential leads and pursuing several theories, including the possibility that the AT&T building was targeted.

Korneski said Sunday that officials were looking at any and all motives and were interviewing acquaintances of Warners to try to determine what may have motivated him.

The bombing took place on a holiday morning well before downtown streets were bustling with activity and was accompanied by a recorded announcement warning anyone nearby that a bomb would soon detonate. Then, for reasons that may never be known, the audio switched to a recording of Petula Clarks 1964 hit Downtown shortly before the blast.

Warner, who public records show had experience with electronics and alarms and who had also worked as a computer consultant for a Nashville realtor, had been regarded as a person of interest in the bombing since at least Saturday, when federal and local investigators converged on the home linked to him.

Federal agents could be seen looking around the property, searching the home and the backyard. A Google Maps image captured in May 2019 had shown a recreational vehicle similar to the one that exploded parked in the backyard, but it was not at the property on Saturday, according to an Associated Press reporter at the scene.

On Sunday morning, police formally named Warner as being under investigation.

Officials said their identification of Warner relied on several key pieces of evidence, including DNA found at the explosion site. Investigators had previously revealed that human remains had been found in the vicinity.

In addition, investigators from the Tennessee Highway Patrol recovered parts from the RV among the wreckage from the blast, and were able to link the vehicle identification number to an RV that was registered to Warner, officials said.

Were still following leads, but right now there is no indication that any other persons were involved, Korneski said. Weve reviewed hours of security video surrounding the recreation vehicle. We saw no other people involved.

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. Suddenly the warning stopped, and Downtown started playing.

The RV exploded shortly afterward, sending black smoke and flames billowing from the heart of downtown Nashvilles tourist scene, an area packed with honky-tonks, restaurants and shops.

Buildings shook and windows shattered streets away from the explosion near a building owned by AT&T that lies one block from the companys office tower, a landmark in downtown.

But on Sunday, just blocks from where the bombing took place, tourists had already begun to fill the sidewalks on Lower Broadway, a central entertainment district. Some took selfies while others tried to get as close as possible to the explosion site, blocked by police barricades.

Earlier Sunday, the officers who responded provided harrowing details, at times getting choked up reliving the moments that led up to the blast.

This is going to tie us together forever, for the rest of my life, Metro Nashville police Officer James Wells, who suffered some hearing loss due to the explosion, told reporters at a news conference. Christmas will never be the same.

Officer Brenna Hosey said she and her colleagues knocked on six or seven doors in nearby apartments to warn people to evacuate. She particularly remembered a startled mother of four children.

I dont have kids but I have cousins and nieces, people who I love who are small, Hosey said, adding she had to plead with the family to leave the building as quickly as possible.
