Authorities said on Sunday that they believe Anthony Quinn Warner was responsible for the Christmas Day explosion that rocked downtown Nashville, Tennessee, and that the 63-year-old died in the blast.

What's new: Four days before the explosion, Warner told a neighbor that “Nashville and the world is never going to forget me," per AP. The neighbor told the news agency that nothing about Warner raised any red flags. “He was just quiet," the neighbor said.

  • Investigators confirmed on Sunday that human remains found at the scene matched Warner's DNA.
  • The Metro Nashville Police Department also released footage of the moment the explosion took place on Sunday evening.
A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.
  • The FBI searched Warner's home in Antioch, a Nashville suburb, on Saturday.
  • Officials said they linked the vehicle identification number of the RV at the blast site to an RV registered to Warner.
  • Authorities do not believe anyone else was involved in the explosion, which injured at least three people.

What they're saying: "We're still following leads right now, there is no indication that any other persons were involved," Doug Korneski, FBI special agent in charge of the Memphis field office, said during a Sunday afternoon press conference.

  • "We still have work to do. Our evidence response teams will continue to process the scene downtown and our agents will continue to follow on every, and each and every tip that we receive," Korneski added.
  • Authorities also said they "were not in the position" to speculate on a motive for the bombing.

The big picture: Investigators have been looking into more than 500 leads and tips that have emerged since the Christmas morning blast.

  • The explosion occurred after a recorded voice blared from the RV, telling residents to evacuate the area and giving a countdown. Also playing was the 1964 song "Downtown" by Petula Clark, who sings about how "the lights are much brighter" and "you can forget all your trouble."
  • AT&T continued to work Sunday to restore cellphone service and emergency service communications after the explosion caused widespread outages in central Tennessee and neighboring states.
  • At least 41 buildings were damaged, the state's governor said Saturday.

Editor's note: This article has been updated with the police release of video footage of the explosion, details of the song that played and new information about Warner.

Taiwan's President Tsai Ing-wen told CNN Thursday that a small number of American troops are on the island for training purposes and she has "faith" the U.S. would defend the democracy against a Chinese military attack.

Why it matters: This is the first time a Taiwanese leader has publicly acknowledged the presence of U.S. troops on the self-governing island since the last U.S. garrison left in 1979, when Washington switched formal diplomatic recognition to Beijing.

The president of New York City's firefighters union told reporters Wednesday that he's advised unvaccinated members to ignore Mayor Bill de Blasio's COVID-19 vaccine mandate for city workers, per Reuters.

Why it matters: Under de Blasio's order that's due to take effect Friday, unvaccinated city employees would be placed on unpaid leave. But Uniformed Firefighters Association head Andrew Ansbro said he told members that "if they choose to remain unvaccinated, they must still report for duty," according to Reuters.
