we're also being told d.n.a. tests are being conducted on human remains found at the scene. today, federal agents raided the home of a person of interest in connection with the explosion. cbs news has learned that law enforcement has identified the man as anthony quinn warner. this google maps image, obtained by cbs news, shows an r.v. behind the wood fence, matching the description of the vehicle that exploded in nashville. an f.b.i. bulletin from the weapons of mass destruction directorate said warner had a similar make and model r.v., and the google street view shows an r.v. parked in the yard of the warners' home. today, part of the downtown area remains a crime scene. >> it's like a giant jigsaw puzzle created by a bomb that throws pieces of evidence across multiple city blocks. >> reporter: there is a picture emerging. investigators have been able to trace the movements of the r.v., and the person driving it back, almost five hours before the blast.

on friday, at 1:20 a.m., it was at the intersection of korean veterans boulevard and second avenue south. at 5:28 a.m., a 911 caller reported that shots were fired in the area. later, there was another 911 call from someone telling the police the recording from the r.v. said the bomb was going to explode. was parlice arrived on scene, the r.v. was spotted parked outside the at&t building. officers noticed blinds and clothes covering the windows. shortly thereafter, the warning of an imminent bomb started blaring through the streets. >> if you hear this message, evacuate now. >> command to all units, this is an explosive device. >> reporter: after the blast, sources say shell casings from a gun were found at the scene, perhaps set off by the large explosion. more leads for investigators to follow, along with about 500 tips.

and right now, it looks like the motive in this incident may be tied to that at&t building. sources are telling cbs news that investigators are looking for leads, trying to see if there were any threats made against that building. remember, the explosive-laden r.v. was parked right near that at&t building. adriana. >> diaz: jeff pegues outside f.b.i. headquarters in washington, thank you. today, tennessee's governor toured downtown nashville, tweeting later that the damage is shocking, and it's a miracle no residents were killed. mola lenghi is there tonight. mola, good evening. >> reporter: well, adriana, as you can imagine, this is not how folks here in nashville expected to begin christmas morning, especially the ones in the downtown area who woke up to police banging on their doors telling them to evacuate. but many of thosepeople credit those very officers with likely saving their lives. this is not what noelle rasmussen expected to see on christmas morning-- parts of her apartment building blown to

the officers didn't explain the threat that ultimately left more than 40 downtown buildings damaged and vehicles in flames. but it all became horrifyingly clear as the family drove away from their apartment building. >> the explosion happened, i saw this huge fireball in the sky, at least twice as tall as our building. i grabbed his arm, and i said, "babe, that's us. that's-- that's us. our house exploded." >> reporter: what was the immediate reaction? >> it was totally surreal. >> reporter: three people were injured. we're told they are going to be okay. meanwhile, the police chief here says that his officers tell him they don't want to be called heroes, insisting they were just doing their job. adriana. >> diaz: it's hard to imagine the pain and the fear they must have been feeling in that moment. mola lenghi in nashville, thank moment. mola lenghi in nashville, thank you. tonight, new pain for the unemployed. their covid benefits have run out, with president trump still

graham was actually with the president on the golf course friday, and graham tweeted the president is "more determined than ever to increase those payments," and graham said he hopes congress is listening. but when it comes to congress, it was house republicans that rejected an effort by democrats to increase these stimulus payments this week. and, adriana, unless the president signs this bill as is, it's looking less and less likely that those checks will go out any time soon. >> diaz: paula reid in florida. thank you. the stimulus bill includes billions for vaccine distribution. today, covid cases worldwide topped 80 million. the u.s. is by far the global leader in confirmed cases with nearly 19 million. more than 331,000 people have died here, and the holidays could make things worse. cbs' lilia luciano is in los angeles. >> reporter: with covid infections smashing records and hospitals pushed to the brink, there is new fear tonight of a post-christmas surge.
