And it has gotten profoundly weird. 

First, it appears that this was a suicide bombing with the remaining tissue samples found on site being identified as Anthony Quinn Warner , a 63-year old “IT Guy”, who transferred his house to some random woman in California in late November, and the truck was blaring the Petula Clark song Downtown before it detonated.

There are also scattered reports that the bombing might have been motivated by 5G conspiracy theories: 

Anthony Quinn Warner was responsible for the Christmas morning explosion that rocked downtown Nashville, officials said Sunday, and he was killed in the blast.

Investigators matched human remains found at the scene with Warner’s DNA, confirming suspicions that he blew himself up in a recreational vehicle, Tennessee Bureau of Investigation Director David Rausch told reporters. Law enforcement said they were still investigating a motive behind the incident.

Warner, 63, was unmarried and rarely ventured from his home, according to neighbors, living for years with his parents and then by himself. He once owned an alarm company, and he protected his home with an array of security cameras, rarely returning a neighborly wave and not responding to an offer of Christmas dinner, neighbors said in interviews.

………

In November, Warner transferred his property at 115 Bakertown Rd. to a Los Angeles woman for “$0,” according to property records of a quitclaim deed. The woman said in a brief telephone interview that the FBI told her not to discuss the matter and declined to comment.

A Nashville real estate firm, Fridrich & Clark Realty, confirmed that Warner worked there as a computer consultant for about 15 years before announcing his retirement earlier this month. “The Tony Warner we knew is a nice person who never exhibited any behavior which was less than professional,” co-owner Steve Fridrich wrote in a statement.

The officers heard a strange recorded warning, which started to play a 15-minute countdown, coming from the RV. Officers started knocking on doors, contacting dispatch to get access codes to buildings, clearing them floor by floor, warning residents who answered to gather family members and safely evacuate.

“That’s stuff that I’ll never forget, the sound of the announcement saying … ‘Evacuate now,’” said Amanda Topping, one of five officers who spoke to reporters during a morning news conference. “Just odd. And I’m pacing back and forth because I kept on having to turn pedestrians around.”

The RV began to play music — officer Tyler Luellen told reporters he later learned it was “Downtown” by Petula Clark. The officers prepared themselves, some going back to their cars for heavier gear.

While it is unknown whether the AT&T building was the intended target, experts on critical infrastructure said the Christmas morning episode makes clear that federal and local authorities and the private sector ought to find ways to reduce their vulnerability, either through moving key pieces to more fortified locations or building in redundancies.

As Alice Liddell would say, “Curiouser and Curiouser.”
