First of all, the rows of conspicuous bottles and cans on the shelves, those with yellow and black biohazard markings, even if you open them, you can't tell the real ingredients.

Unobtrusive, unexpected, and accessible in case of emergency, Jack's gaze swept over the bits and pieces on the table, including the pen, and he dismantled everything that could be used as a container.

Finally, his eyes fell on the corpse on the ground, and he was a little dizzy, and he should have given priority to checking the deceased's belongings.

"Garcia, help me check that Nichols' medical records show that he has asthma or a similar respiratory illness?"

"No, he's in good health, he doesn't even have high blood pressure." Garcia's reply was quickly heard over the intercom.

"That's it, I think we've found the 'antidote.'" Jack flashed the nebulizer in his hand to Dr. Kimura.

At the same time, Dr. Kimura made a new discovery.

"The 'notes' you made me look at look like a draft of a paper, with references and a table of contents, and some notes written in red pen on the side, like a teacher revising the paper."

"So Nichols was really mentoring a student, and we were right in the first place." But then Jack was a little depressed.

"But Garcia has already compared that the list of people related to the bookstore does not involve biochemistry or microbiology, and the bookstore also mainly sells literary and first-edition used books."

Why don't you write a paper without signing it first, how can people check it?

"No, no, let me finish, I don't think this paper was written by a student majoring in natural sciences or biology, it's a social science paper, and it devotes a lot of chapters to the establishment of a classification system for injuries and mobile emergency rooms."

Dr. Kimura showed a few pages of the relevant content in front of Jack's eyes, and some familiar sentences came into his eyes.

"It's unfortunate that the country is unprepared, every household has to be equipped with at least two months' dose of ciprofloxacin, and hospitals need to set up a biosafety level 4 decontamination department."

Jack's mind flashed to him, their thinking was limited to science and engineering students, but what if the guy who caused the trouble was a damn liberal arts student.

"Garcia, do another cross-search of the list of students and bookstore-related people from all the universities in the local area related to social sciences, urban planning and management, public policy."

A short time later, Garcia's excited answer came over the intercom.

"Bingo, got you, there's a guy named Chad Brown, who attends the University of Maryland's School of Public Policy, and is the same person as Chad Brown, the former clerk at the bookstore."

"That's him!" Jack hands the respirator to Dr. Kimura.

"Rhett handed it over to you, doctor, analyze the drug ingredients as soon as possible, and those four patients may be saved."

He walked quickly out of the lab and into the cleaning tent.

When Jack and Hodchner, who were waiting outside, rushed back to the command center, Garcia sent Chad Brown's details to him.

When Jiejie sent these materials into the conference room, General Whitworth also walked in with a copy of them.

"Chad Brown, who has been pursuing a Ph.D. on and off for five years at the University of Maryland's School of Public Policy, currently has no stable job, and his ex-girlfriend has filed for a physical restraining order against him."

"He was arrested twice for attending a protest rally in Washington, D.C., and he applied for a general assistant position at Fort Detrick four times, all of which were denied."

As soon as Jiejie's words fell, General Whitworth opened the information he had brought.

"This was Chad Brown's job application, and the reason for the rejection was that he had failed a psychiatric evaluation, and that psychologists thought he was too radical and mentally unstable."

General Whitworth's face was a little gleeful.

"He had a strong obsession with getting into Fort Detrick and a desperate quest for identity, so he found Nichols." Jiejie continued.

"I reached out to his dissertation advisor, and in his opening paper, he talked about how to easily make anthrax, and I believe it was because of this similarity that he and Dr. Nichols hit it off."

"And Chad Brown's sister, I just talked to her, and they haven't been in touch for years, but his sister told me about Quiet Hill Park, where he once proposed to a girl and was rejected."

He then worked in a bookstore to earn tuition to support his studies, but was fired by his boss because of frequent arguments with customers.

"So both the bookstore and the park mean rejection for him, that's the motivation." Hodchner said as he dialed Emily's phone, "Rosie and Emily should be at his house by now." ”

"I was about to call you, and while I didn't catch anyone, I think I found out how Chad Brown was going to release anthrax, and he put powder into a light bulb and smashed it on the ground, which was like an anthrax bomb."

Emily spoke quickly on the phone, "I found fragments of a light bulb in the trash can for testing, and Rosie found a tagged subway map. ”

"So what do we do next?" Jiejie asked anxiously.

General Whitworth held up a finger to signal everyone to be quiet, then dialed a phone call, whispered a few questions, and hung up with a solemn face.

"Dr. Nichols was once commissioned by the Senate to write a classified study simulating an anthrax attack on the Washington subway system."

He specifically noted that the main line, which is the red line, is the most vulnerable to attack, and the tunnel has strong winds, the largest flow of people, and the most significant lethality.

"I recommend immediately arranging personnel at all stations on the main line and closely monitoring them."

Hodgner pondered for a moment, shook his head and objected, "It can be arranged to be deployed in the subway station immediately, but I don't think the target of his attack is the main subway line." ”

General Whitworth, who had already shown some kindness to the BAU group, couldn't help but blow his beard.

"Didn't you say that he and Nichols agreed with each other and copied his ideas?"

"We also said that the location he chose had potential meaning for him, and now we have found it, which represents the meaning of rejection and denial."

Hodchner looked at the general seriously, and his tone was very affirmative, "There is another place where he has been rejected again and again, and where is that?" ”

"It's Fort Detrick!" Rosie, on the other side of the phone, said loudly.

"There's no way he's going to get in." General Whitworth retorted loudly, "Not even a fly can fly in without my consent." ”
