Perpetrator
Authorities concluded that 63-year-old Anthony Quinn Warner, a longtime Nashville resident,[46][47] was the bomber, that his remains were found in the wreckage, and that there was no indication anyone else was involved.[1][48][49]
Warner was raised in Nashville's Antioch neighborhood and graduated from Antioch High School in the mid-1970s.[48] His father, Charles Bernard Warner, had been a BellSouth employee in Nashville, which merged with AT&T in 2006.[50] Anthony Warner worked in a series of information technology jobs,[48] including as an independent computer technician contracted with a real estate firm, and had owned a company licensed to produce burglar alarms from 1993 to 1998.[20][49] He served two years' probation for felony marijuana possession in 1978 but had no other arrests or criminal record.[48][42] Late in his life, Warner was involved in a family dispute that went to court after he transferred ownership of a family home to himself directly before his brother Steve's death in 2018; the case was dismissed in 2019.[40]
In the weeks before the bombing, Warner quit his job, gave away his car, and executed a quitclaim deed transferring his Nashville duplex home to a Los Angeles woman for $0.[9][48] He had previously executed a quitclaim deed for a different Nashville house in 2019, transferring his interest in the home to the same woman.[51] Reportedly, Warner had told the woman to whom he gave his car that he had cancer, but it is not known whether that was true. A neighbor said that just before Christmas, Warner had said, "Nashville and the world is never going to forget me."[52] Credit card and receipt records examined by investigators showed that Warner had purchased components that could be used to make bombs.[43][53]
Authorities initially said that Warner had not attracted the attention of police before the bombing,[1][54] but it was later revealed that Warner's friend Pamela Perry and her attorney had met with police on 2019.08.21. Perry said that Warner had been making bombs in the RV, and her attorney, who previously represented Warner, said he believed her.[55][56][57][58] Police were unable to make contact with Warner; did not enter Warner's home, yard, or RV; and closed the case as unfounded after an officer observing the home for a few days reported no evidence of bomb-making.[57][59]
Search for motives
Investigators searched Warner's home in Nashville after the bombing[4] and seized several items, including a computer and a portable storage device.[53] Google Street View images of his address appeared to show an RV similar to the one used in the bombing.[63][64] Neighbors of the property told WKRN-TV news that they recognized the RV in the image released by police, saying that it had sat unused for years until Warner began giving it renewed attention about a month before the bombing and that it had disappeared from the property days before the bombing.[65] Neighbors called him reclusive[49]
