Police Detective

Sometimes, Bai Song can be like a dragon going out to sea, winning with one blow. When faced with some cases, he can rush forward quickly without stopping for a moment.

But sometimes, he can still be calm when facing big things, especially after what happened last time.

As an open class, Bai Song listened from beginning to end without showing any impatience. After class, he and Wang Huadong invited Ding Jianguo to dinner.

The reason why he wanted to accompany him was because Wang Huadong was afraid of embarrassment when inviting guests, and with such an invitation, even if the girl didn't agree, it wouldn't be embarrassing. They are all "teaching assistants" and have lunch at work.

As for Ding Jianguo, he agreed to the two of them, but they just ate in the cafeteria.

This is a bit embarrassing, neither of them have meal cards, and the one who is treating us is...

However, this is a good start. In Wang Huadong's words, this is a reason to treat the young lady to dinner next time.

After they separated, Bai Song got into Wang Huadong's car. As soon as he got in the car, he immediately took out his mobile phone and dialed the number of the Qin detachment.

"Qin Detachment, I have an idea that I want to test." Bai Song said bluntly.

"Wait a moment." The Qin detachment was having a meeting in the city and left the meeting place directly.

After almost twenty seconds, Qin detachment said: "You said it."

"I want to do a test on the money that is currently seized about Tian Huan."

"Test? How to test?" Qin detachment was a little confused, "We have tested the money and there is nothing contraband."

"Has every one been checked?" Bai Song asked.

"That's definitely not the case, but the fourth team also hired professional drug detection dogs from the sixth team." Detachment Qin didn't understand what Bai Song wanted to say.

When Bai Song didn't speak, detachment Qin added: "Whatever you think, just say it."

"Okay", Bai Song was not afraid of being abrupt, and said directly: "This pile of money, especially the bottom few piles, I want to test whether the paper contains highly toxic substances."

"Is there any specific poison conjecture?" Qin detachment said calmly. As a forensic doctor, his understanding of this aspect is far better than that of Bai Song. Naturally, he also knows the benefits of narrowing the detection area.

"Botulinum toxin." Bai Song expressed his guess: "But I have no idea which strain it is."

"Botulinum toxin?" Detachment Qin thought for a moment, "Okay, I understand. I will arrange for someone to be sent to the Criminal Division for Prosecution immediately."

"Thank you, Detachment Qin. Wang Huadong and I will also rush over." Bai Song hung up the phone.

…

After turning off the phone, Wang Huadong immediately turned the car around and without asking, set foot on the road to the Criminal Division.

"Why is there poison in money?" Wang Huadong asked.

"I'm not sure, it's just a guess." Bai Song said truthfully.

"You've never made any unreasonable guesses. Stop being too pretentious and tell me." As a member of the project, Wang Huadong is extremely eager to know more.

"I have been planning a perfect crime about Tian Huan." Bai Song looked out the car window: "How can I make Tian Huan die because of me."

"So?" Wang Huadong still didn't understand.

"Have you seen the video of Tian Huan's interrogation?" Bai Song asked.

"I have read it several times. I have also participated in interrogations and found no problems." Wang Huadong shook his head and was a little distracted while driving.

"Do you still remember that he had a habit when flipping through transcripts?" Bai Song asked.

"Habit? What kind of habit can you have when reading transcripts?" Wang Huadong struggled to recall and said uncertainly, "He prefers to spit?"

"Yes." Bai Song said: "He is from the south. When he lives in the north, he will feel dry to some extent. I don't know why. Every time he turns over the paper, he likes to dip it in saliva. This habit is stronger than the average person. I compared it with Lei Chaoyang last time, and this is even more true, because Lei Chaoyang is also from the south."

Wang Huadong was even more confused. What does this matter?

"What do you think would be Tian Huan's plan if I died in the car accident in April and Tian Huan's mission was completed?" Bai Song did not answer directly.

"Run away, let's talk about going abroad." Wang Huadong blurted out.

"Of course this is true, but in a case like this, is it safe if he escapes?" Bai Song said: "ZZ has committed crimes that cannot be extradited to many countries, but if he kills me, he will have no one to protect him wherever he goes, and he will be extradited sooner or later. "

"So," Bai Song said with certainty, "Tian Huan himself doesn't know that if he successfully completes the task, he will definitely not survive. The people behind him will not even let the driver go, so how can they let him go? So? , Tian Huan will definitely die, and the cause of his death is related to the existing clues, but it is difficult to guess.

According to common sense, if Tian Huan didn't tell us about the money we seized, we wouldn't be able to find it.

However, after the case failed, Tian Huan used the money to fight the matter on his own.

In other words, this money is part of Plan B.

However, if he succeeds, what will he do with the money when executing Plan A?

He must know that he cannot carry so much cash on the plane, but will he really give up so much money? Of course it's impossible.

At this time, Tian Huan definitely wants to keep the money privately, and he has no relatives in Tianhua City. At this time, it is impossible for him to dare to go to the bank to exchange or deposit the money. Then he has only one option, which is to hide it. In a place where no one knows. In the future, if he has the opportunity to return to China, or if his family and friends come to Tianhua City, he can still withdraw the money.

And Tian Huan likes money so much, so he must count it. After all, when it comes to escaping, he hasn't bought the ticket yet, so there is no need to race against time. He will definitely count the money with his own hands.

This money may have been in the millions before, but the bottom part could not be spent from the beginning of the plan. This was part of Plan B.

Therefore, if there are some highly toxic ingredients in the bottom few piles of money, Tian Huan, who likes to count money with saliva, will die.

Moreover, the poisoning time is not instantaneous. If it is botulinum toxin, it usually takes several hours.

He counted the money, hid it, left, and died of poison.

After he died, we couldn't even find the source of the money and the toxins, because he hid them himself.

At that time, it will be really difficult to solve the case of his death. "

"Would he still spit on moldy money?" Wang Huadong was a little confused when he heard this. He can relate to this.

"The moldy money is evidence to us. We will definitely use gloves until the case is over. The money will also be sent to the People's Bank for replacement. But to him, it is money." Bai Song curled his lips: "What rich people like you don't understand is that if 100 yuan falls into a cesspit, many people will find a way to get it out, let alone so much money?"
