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.
  • 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.

Russian opposition leader Alexey Navalny was detained upon his return to Moscow on Sunday, which came five months after he was poisoned with the nerve agent Novichok. He returned despite being warned that he would be arrested.

The latest: Navalny was stopped at a customs checkpoint and led away alone by officers. He appeared to hug his wife goodbye, and his spokesman reports that his lawyer was not allowed to accompany him.
