Once this mind is opened, things are different.

The sources of ether and carbon monoxide can be explained.

Zhang Zuo can get it.

The previous case confirmed that Zhang Zuo was a rich second generation with a bit of messy ability, but now Bai Song began to recall some things in his mind, and he felt more and more wrong.

Bai Song thought about Zhang Zuo's affairs for a long time, and then began to diverge his thinking, remembering a lot of things.

...

"Bai Song, I'm all going to the cafeteria, aren't you going?" Qin Wushuang stood at the door of the conference room.

"White pine??? white pine. ”

If Director Ma Donglai was here, he would have waited quietly for Bai Song to finish thinking about it, but the Qin detachment didn't have such a deep understanding of Bai Song.

"Huh?" Bai Song relieved himself, "Qin detachment, what's the matter?"

"What are you thinking?" Qin Wushuang asked curiously.

"Oh oh, oh, the case. Bai Song gently patted his forehead twice with his one-handed index finger and middle finger: "It's a little conjecture." ”

"Hmm, then I interrupted your thinking?" Qin Wushuang was a little embarrassed.

Bai Song was quite moved, after contacting so many leaders, the Qin detachment is really the most leaderless, which is also the characteristic of technical personnel.

"No, no, I just got into a dead end. There are some things that don't make sense just by thinking about them, you have to actually look them up. Bai Song stretched.

"That's simple, if there is anything that needs to be checked, our detachment, including the sub-bureau, will definitely support you. Qin Wushuang breathed a sigh of relief when he heard this.

"Qin detachment", Bai Song stood up at this time, "I have an idea, but it is not very easy to verify. ”

Bai Song didn't slow down, otherwise he wouldn't have sat for a long time.

"You say. Qin Wushuang nodded.

"I want to go to prison. ”

"Yes. ”

"I want to interrogate Wang Ruoyi again. ”

"No problem. ”

"I want to drive a school bus in and see if Wang Ruoyi can drive. ”

"But... What are you kidding?" Qin Wushuang was stunned for a moment: "Do you know that it's a prison, test cars for prisoners, how is this possible." ”

"Driving a school bus, there is a secondary brake, and the automatic transmission is OK. There will be no danger, I'll take the co-pilot. Bai Song said.

"Hmm...," the Qin detachment thought for a moment, "The question is, how can you be sure that the person you are talking about will cooperate with you?"

"If she is not worthy of me, then it is likely that there is a ghost in her heart, and in this way, I will make up my mind to check Zhang Zuo. Bai Song said: "After all, it is easier to check the people in prison. ”

"You're afraid of startling the snake, aren't you?" Qin Wushuang thought for a while: "Tell me about the Zhang Zuo you mentioned." ”

"Good. Bai Song began to tell the ins and outs of what he found in these cases, and talked for more than ten minutes.

...

"In other words, it is possible that Zhang Zuo has substances such as ether and carbon monoxide in his hands? I think it is necessary to investigate this matter directly, and there is no need to check the one you said..."The Qin detachment suddenly said: "Wait, you haven't told me yet, why do you want to try Wang Ruoyi's driving skills?"

"I met a friend named Zheng Can, who bought his driver's license in the first place. In previous years, driver's license management was chaotic, and there were quite a few places where it was easy to obtain a driver's license. Bai Song said: "I think about it now, at the beginning, when Wang Ruoyi was in the case, she had just learned her driver's license, and in her situation, it was not very realistic to learn it well." Moreover, she doesn't have a car herself, I've been to her house, her house is a villa, and there is no car in the yard, only her father has a car.

In this Li Yanan incident, Li Yanan encountered a case of death, and his spirit was highly stressed.

And after Wang Ruoyi killed people and broke the corpse at that time, he drove a large MPV model from Tianbei District to Jiuhe District, and then he had to roll down such a heavy iron bucket by himself, not that it couldn't be done, but this required a more reliable car skill and skill.

I now have reason to suspect that Zhang Zuo was also involved in this murder. ”

"But didn't you just say that Zhang Zuo is infatuated with Wang Ruoyi?" asked the Qin detachment.

"The situation at that time was generally believed to be something that Wang Ruoyi controlled to do on the left. Bai Song said: "Is there a possibility, in fact, from beginning to end, Zhang Zuo is controlling Wang Ruoyi?"

"I know that this Wang Qianyi you are talking about, this person is indeed not a simple person, and Wang Ruoyi you mentioned, according to some of her situations you have talked about, is also a very shrewd person, right?"

"Very shrewd indeed. Bai Song nodded: "But it is really possible for a little girl of this age to drill the horns, and it is not impossible to be used by others."

I really didn't think about it that way before, after all, I think this little girl can always avoid detection, and she is a smart person.

But later, in the first and second trials, I found out that she didn't want to defend anything at all, and even gave me the feeling that she didn't want to live anymore and was bent on dying.

When you think about it today, there may be a problem here. ”

"Well, it stands to reason that this is indeed the case, and of so many murderers I have met over the years, none of them really want to die. I have dealt with several scenes, that is, I really had a conflict with my wife, and I was bent on death, and after one party killed the other party in this kind of scene, I committed suicide directly. Apart from this kind of people, there are not many murderers who really want to die. Qin Wushuang said.

"Well, as you said, it's true, I also thought it was strange before, but I didn't think about Zhang Zuo this aspect, and I still judged people by their appearance. Bai Song gestured with his hand: "This person has a problem." ”

"If it's really what you said, Zhang Zuo is really not an ordinary person, this matter really can't be investigated, in case there are finally some clues, it's not good if you can't find it anymore, after all, Wang Ruoyi has already pleaded guilty to the law... Well, let's go to dinner first, and talk to Wei Ju when we eat later, by the way, you can tell me about Zhang Zuo's other situation by the way. ”

...

A lunch that was supposed to be celebrated, because of the old age of Bai Song and the Qin detachment, it became two groups.

The theme cannot be changed, all departments must leave, the murder case has been solved, and even if it is to handle the case, it is impossible to leave so many people.

Therefore, on behalf of the Municipal Bureau, the Wei Bureau thanked the participating teams and expressed the concern of the city leaders for all the police, and hoped that everyone would make persistent efforts to become bigger and stronger, and create more brilliance.

However, at the same time, Wei Ju's heart had already drifted out of the clouds.

Individually, the Qin detachment mentioned to him the possible source of ether, but it was only a few whispers, and he didn't need to listen to the truth.

However, Qin Wushuang is a very strict person, and Wei Ju knows it. So Qin Wushuang said that it was possible, then there would be seven or eight.
