In addition to her well-documented history of depression and erratic online behavior, the trans former Amazon employee who was arrested and charged with one of the biggest bank data breaches in history earlier this week also threatened to shoot up an unnamed social media, Bloomberg reports, citing court documents filed by prosecutors.

Paige Thompson, 33, was arrested during a raid of her house Monday morning and charged with illegally accessing Capital One’s files. Sensitive data belonging to more than 100 million people who have applied for credit cards at Capital One may have been exposed, including names, dates of birth and about 140,000 social security numbers.

But Thompson's roommate and landlord, a convicted felon named Park Quan, was also arrested after agents found more than a dozen guns and explosive material in his room. In arguing that Quan, who has at least three prior felony convictions mostly relating to illegal possession of firearms, should also be detained, prosecutors said the firearms were related to their case since Thompson had been subject to multiple restraining orders, and had made "express threats to harm herself or others."

"In fact, in late May 2019, Person 1 threatened to 'shoot up' the office of a California social media company," prosecutors wrote in a filing, referring to Thompson. A person familiar with the case said that "Person 1" is Thompson.

Following Thompson's arrest, Amazon and the FBI have been trying to determine if she accessed files belonging to any other AWS customers or other companies and institutions that are mentioned in her social media posts.

Remember, there actually was a shooting at the offices of YouTube not too long ago.

Italian banking giant UniCredit also said it was investigating the possibility of a breach, as did Ford, and the Ohio Department of Transportation. On Thursday, Linda Lacewell, New York’s financial services superintendent, said UniCredit had alerted her office to "the possible loss of consumer data related to the Capital One data breach."

Michigan State University, which was also mentioned, said it had found no evidence of a breach.

Amazon said it has so far found no evidence that Thompson hacked into the files of other customers.
