American Anthony Quinn Warner is passionate about technology, has little contact with neighbors and donates two homes to a girl younger than many years before detonating car bombs in Nashville.

Warner, 63, was identified by authorities as the only suspect causing a picnic car bomb outside of Nashville's telecom network company AT&T building on Christmas morning December 25, injuring three people.

Warner has worked in a number of IT jobs, once owned a company specializing in anti-theft systems and most recently as an independent computer technician for real estate company Fridrich & Clark in Nashville.

Warner's home in Antioch and office in Nashville were searched by federal agents on December 26.

Tennesse state business records show that Warner has registered to set up an anti-theft device manufacturing company Custom Alarms & Electronics.

Some neighbors described Warner as "odd."

Neighbor Steve Schmoldt has lived next door to the Warner's house for more than two decades.

Schmoldt said that his wife used to bring Christmas food to Warner, but Warner did not open the door.

"Politically, he never hung any pro-party banners or flags in the backyard or on the windows. If he had some political opinion, he couldn't show it out," Schmoldt said.

Schmoldt said the picnic car, now confirmed to have exploded on December 25, had been parked outside of Warner's home for years and just a few weeks ago, Warner made the entrance to the fence and drove in.

Rick Laude, who has been living near the Warner's house since 2010, says that "recluse" is the perfect word to describe Warner.

A cousin said that Warner "loves phones and electronics" just like his father passed away in 2011. "He is always very quiet. When the family gets together, he will come in a picnic drive, he

It is noteworthy that Warner donated a $ 160,000 home to Michelle Swing, 29 in Los Angeles, in a resignation deed on November 25.

However, Warner is believed to have notified Swing of the transfer of ownership in a letter last month.

Swing declined to disclose to the media whether she had met Warner or had any family relationships with him.

Swing studied Marketing and Business at the University of Tennessee at Knoxville.

Warner also transferred ownership of another home on Bakertown Road to Swing in January 2019.

The FBI is believed to be investigating whether Warner was motivated by the conspiracy theories that Americans were being tracked by 5G technology.

A man near the scene said he had seen a picnic car similar to an exploding car parked in the area several times in the past few weeks, suggesting that Warner may have surveyed the site before the attack.

Meanwhile, Schmoldt said that when he read about the people on the picnic car issued a warning 15 minutes before the explosion to avoid casualties, he immediately thought of Warner's devotion to pets over the years.

Schmoldt said Warner "took great care of the dogs" and even built a doorway for dogs to walk around as they get older.
