The man thought to have been behind Nashville’s Christmas Day explosion reportedly told a neighbour days before the incident that “Nashville and the world” were never going to forget him.
Anthony Quinn Warner, 63, killed himself and injured three people nearby when a bomb in his camper van exploded in the heart of the city.
Neighbour Rick Laude has told The Associated Press he was speechless on learning authorities had identified Warner as the suspect in the powerful blast, which also damaged dozens of buildings.
Warner had smiled and said: “Oh yeah, Nashville and the world is never going to forget me.”
Mr Laude said he did not think much of the remark and thought Warner only meant “something good” was going to happen for him financially.
“Nothing about this guy raised any red flags,” Mr Laude said. “He was just quiet.”
“I knew that he was just a recluse,” he said.
As investigators continued to search for a motive, body camera video released late Monday by Nashville police offered more insight to the moments leading up to the explosion and its aftermath.
Car alarms and sirens wailed as a police dispatch voice called for all available personnel and people stumbled through downtown streets littered with glass.
Warner left behind clues that suggest he planned the bombing and intended to kill himself, but a clear motive remained elusive.
