PICTURED: 'Paranoid' homeowner James Yoo, 56, whose Arlington home exploded after suspect fired over THIRTY flares is believed dead - as social media posts include calling his ex-wife a 'witch' and 'f*** America'

A homeowner who allegedly fired more than thirty flares at SWAT officers before his home exploded had a bizarre online history - as he called his ex-wife a 'witch', and wrote a series of anti-America posts. 

James Yoo, the Arlington man suspected of triggering an explosion at his Virginia home, was a paranoid conspiracy theorist who believed that the U.S. government wanted to kill him, DailyMail.com has learned.

Yoo is presumed dead after his property erupted into a fireball, police confirmed on Tuesday. Human remains were found within the charred property.  

His now-deleted LinkedIn account contained a string of bizarre ramblings, including a recent post from December 1 that claimed his neighbors were spies who wanted to carry out his assassination.

His profile described him as the former Head of Information and Physical Security for an international telecommunication company.'

Yoo’s name has now been officially released by Arlington County police, after public records linked the long-time Virginia resident to the address where the blast took place late on Monday night.

The 56-year-old, described by fellow residents of North Burlington Street as a ‘loner’, believed that locals were carrying out surveillance operations on his house and relaying information to the U.S. authorities.

‘Jamie/Rosemary and Lance and her two children are spies and act as buffers collecting my information and then delivering to their handlers,’ Yoo wrote in the unhinged social media entry.

He bizarrely claimed that they were ‘working with the witch and the alien’ plotting a ‘surprise attack’ against him on December 7, the anniversary of the Pearl Harbor attack.

The posts refer to his ex-wife as a 'witch,' and anti-U.S. slogans including '#F---AMERICA.' 

He ranted: ‘This is how White people operate and have the luxury of outnumbering all other ‘races’ by almost 7 to 1 in 'Merica.’

Yoo provided no evidence for his unfounded allegations, but DailyMail.com can reveal that he has a long history of filing lawsuits against state and federal authorities.

He launched a 2018 case in New York against family members, including ex-wife Stephanie, and Rochester General Hospital for allegedly detaining him against his will.

But his suit was thrown out by judges, who dismissed it as ‘frivolous.’

‘The Court has carefully reviewed each page of Plaintiff's submissions. Plaintiff's Complaint consists of delusional-sounding allegations intermixed with other statements that seem more factual,’ the court document reads.

‘Plaintiff believes he is the victim of conspiracy against him by his sister, his ex-wife, and others including RGH. Plaintiff believes, for example, that his sister, ex-wife and RGH conspired to prevent him from obtaining an attorney.’

Dismissing his complaint, the judges said that Yoo ‘apparently believes there is a connection between the alleged conspiracy, the terrorism on September 11, 2001, and the current investigation into the 2016 presidential election by Special Counsel Robert Mueller.’

Yoo had made attempts to contact Mueller, the court documents show, to warn him of those so-called links.

DailyMail.com can also reveal that his ex-wife Stephanie had filed for divorce on March 30 2017, citing ‘the irretrievable breakdown of their relationship.

She won a court ruling rubber-stamping their split in the December of the following year.

Yoo was told to pay her a sum of $80,000 as well as buy her out of her share of their now-destroyed former martial home for the sum of $150,000.

The divorce records make no mention of any custody arrangements, suggesting the couple did not have any children.

A police spokeswoman said they had come to execute a search warrant when the suspect, believed to be Yoo, discharged 30 to 40 shots of the flare gun.

Emily Saxon, a 30-year-old nurse, said that blast sounded like an 'earthquake' and the shockwaves felt like 'a car had run through my living room'

Sam Kin, a 25-year-old consultant who lived next door to Yoo, filmed the police trying to coax the 56-year-old out of the house.

He said the explosion was 'traumatizing' after getting hit by the shockwave.

'I am going to see my therapist right now,' Kim told DailyMail.com

Astounding video showed the house erupt, sending debris in all directions as a SWAT vehicle sat outside. The sky was lit up in bright orange as glowing particles of the explosion fell down over the Virginia neighborhood.

Huge plumes of smoke cast a thick dark fog over the street, obscuring parked cars and darkening the scene.

Neighbors said a man inside the home fired a flare before the explosion - although it is unclear why. Multiple rounds are said to have been blasted out of a weapon, prompting a call to police, who quickly arrived at the scene.

After SWAT teams arrived, the unidentified person inside the duplex began firing at officers, it is claimed. They prepared to enter the property - only for it to explode in a huge blast that sent debris and a fireball roaring into the sky.

No serious injuries were suffered by police, though authorities said the fate of the suspect inside was unclear, unable to get into the house. The FBI has since joined the investigation into unpicking exactly what happened on Monday night.

In their latest update, Arlington Police said: 'At approximately 4:45 p.m. on December 4, the Arlington County Police Department was dispatched to the 800 block of N. Burlington Street for the report of possible shots heard. 

'The preliminary investigation indicated a suspect discharged a flare gun approximately 30 – 40 times from inside his residence into the surrounding neighborhood. No property damage or injuries were reported related to the discharge of the flare gun.

'During the course of the investigation, officers obtained a search warrant for the suspect’s residence and attempted to make contact with the suspect over the telephone and through loudspeakers. 

'The suspect did not respond and remained barricaded inside the residence. As officers were attempting to execute the search warrant, the suspect discharged several rounds, from what is believed to be a firearm, inside the home. 

'Subsequently, at approximately 8:25 p.m., an explosion occurred at the residence. The investigation into the circumstances of the explosion are ongoing.

'The Arlington County Fire Department responded to the scene to extinguish the fire. As of approximately 10:30 p.m., the fire is under control and crews continue to battle small spot fires.

'Three officers reported minor injuries and there were no transports to the hospital related to this incident. The investigation is ongoing.'
