Investigators said on Sunday that in the explosion on Christmas morning, the suspect swayed in downtown Nashville, Tennessee, and was identified as 63-year-old Anthony Quinn Warner and died in the explosion.
Authorities told reporters that state and federal investigators compared the DNA at the explosion site with items collected from Warner and relatives.
Douglas Korenski, the head of the FBI’s Memphis foreign office, said investigators also matched the RV identification number, which officials said was blown up by a vehicle registered with Warner Corporation.
The surveillance video obtained by investigators showed that no other people were seen around the vehicle when the explosion occurred.
Nashville Police Chief John Drake said: “We can tell you that Anthony Warner is the perpetrator of this terrible crime.”
Donald Q. Cochran, the U.S. Attorney in Central Tennessee, added that Warner was killed by a bomb “present” and was killed in the explosion.
Officials declined to say whether they have determined which explosives were used. Kolensky said that investigators are also trying to find the possible cause of the explosion, which occurred at 6:30 am local time on December 25, when the police were responding to the shooting in the area.
Respondents heard the warning that the RV speaker system about to be parked outside the AT&T building exploded. The police also heard the vehicle playing the song “Downtown” sung by Petula Clark.
At another press conference earlier on Sunday, one of the responders, James Wells, described the loss of a foothold and temporary deafness after the vehicle exploded.
The company said on Sunday that an estimated 41 companies were damaged in the bombing, including the AT&T building, which suffered “significant” damage. Nashville’s 911 system was temporarily suspended, planes at Nashville International Airport were grounded, and services in Kentucky and Alabama were suspended.
The company said in a statement on Sunday that it has restored power to the building’s multiple floors and deployed 25 temporary satellite base stations to the city.
The company said that although more than 90% of AT&T’s wireless network can still work, only a small part of its business and broadband services can operate normally.
