Seven Hundred and Sixtieth Chapters Reveal the Truth

"I... I, I, I, I will check the location of Dou Zili's cell phone now," Zeng Ke said in a panic, "Team leader, you... you, you, you, you, hurry up and call Sister Wu?"

"Oh..." Zhao Yu nodded repeatedly, and reached out to pick up the phone.

If Zeng Ke hadn't reminded him, he really wouldn't have thought of this. Yesterday, when he was talking to the little girl selling fish, Dou Zili had been watching seriously for a long time.

If the little girl's mother was arrested by Dou Zili, then he probably knew the little girl. Therefore, Dou Zili should have been aware of it.

Now Wu Xiumin is investigating this matter, if Dou Zili is really following her, it might be really dangerous.

Just now, after listening to Director Wang Chenggang, Dou Zili went to deal with yesterday's wharf fight. However, no one can be sure now, he must be at the Quliang police station!

Thinking that Wu Xiumin might be in danger, Zhao Yu hastily pressed Wu Xiumin's phone number. However, before the call was connected, Zhao Yu suddenly hung up again.

No……

wrong……

In an instant, Zhao Yu didn't know what to think of, and turned off the phone and put it on the table.

"Hey, team leader, it's urgent. What are you waiting for?" Zeng Ke quickly retrieved the phone's location, and became even more anxious when he saw that Zhao Yu hadn't called.

"No..." Zhao Yu's eyes froze on one point, as if stuck on a certain thought, and after a few seconds, he shook his head gently and said, "Don't worry, Sister Wu is fine!"

"It's okay? Why?" Zeng Ke turned around and asked, "That kind of anesthesia mixture is not something that ordinary people can make. This must be what Dou Zili learned from the girl's mother when he was a child! Obviously, Dou Zili has a serious suspicion! Team leader... "

"Hmm... Zeng Ke..." Zhao Yu said meaningfully, "Have you noticed that Dou Zili has already set up a perfect good situation for himself, so how could he break this good situation with his own hands?"

"Ah? You said...what did you say?" Zeng Ke grinned in surprise.

"It would be great if Dou Zili really attacked Wu Xiumin!" Zhao Yu sighed softly, "But he wouldn't be that stupid! Think about it carefully, even if we know that Dou Zili is the tower guard." Even if, the cigarette butt is covered with his saliva and fingerprints! Even if, we know that his method of using tranquilizers is learned from the criminals he caught! But so what!?"

"So what?" Zeng Ke was stunned for a moment, and finally realized after thinking for a long time, "What do you mean, even if we suspect him, we can't make him confess?"

"Yes!" Zhao Yu nodded, "Dou Zili is the captain of the criminal police, and he knows all the procedures of criminal crimes very well! So, no matter how much we doubt, even if it is an interrogation, as long as he clenches his teeth, there is nothing we can do about it." He!"

"So..." Zeng Ke scratched his head, "So... we still have to find Guo Yihang! But... now it seems that the possibility of Guo Yihang still alive is very slim..."

"Yes!" Zhao Yu said, "In the vast sea, if Dou Zili hides the corpse and the murder weapon, we will never be able to find it! This is his most powerful point!"

"This... so..." Zeng Ke frowned and said, "Dou Zili is confident now? He is not afraid of us going to investigate his background at all! All he needs to do is... do nothing? Then..." He pondered After a while, he said, "Can we try the conventional methods, such as alibi or something..."

"I think it's probably useless!" Zhao Yu shook his head, "If he can handle such a big round, I'm afraid he has already prepared everything!

"Grandma is an idiot. You really can't measure people by their looks. I never thought that this sloppy smoker would fool all of us!"

"Well, this is probably the most bizarre case I've ever seen in my life!" Zeng Ke had called out the location of Dou Zili's cell phone while speaking. According to the location of the mobile phone, Dou Zili was indeed in the Quliang police station.

It seems that he was just dealing with yesterday's wharf fight just as Director Wang Chenggang said.

"Leader, since this is the case...then we have nothing to do with him?" Zeng Ke gritted his teeth and asked, "We should at least search his home, what if we can find something like a sedative? "

"No! Before we have absolute evidence and complete confidence, we must not startle the snake! Otherwise..." Zhao Yu narrowed his eyes and said, "We really have no chance!"

As soon as he finished speaking, the clever Zeng Ke immediately sensed the taste in Zhao Yu's tone, hurriedly widened his eyes, and asked eagerly: "Why, team leader, don't tell me...do you have a way to deal with him?"

"Joke! Otherwise... how can I be your team leader?" Zhao Yu looked at the computer screen and said coldly, "I can't guarantee other ideas, but when it comes to yin people, I am an expert The expert in!

"Come on, Zeng Ke, next, we have a lot of work! If the real culprit is not Dou Zili, then it's fine, but if it's really him, I have to let him reveal his true colors!!!"

...

After determining the target, Zhao Yu and Zeng Ke began to design their plan to solve the case. Meanwhile, Zhao Yu called several people in succession, besides Wu Xiumin and Ran Tao, there was also the forensic doctor Gao Facai.

These few people were the people Zhao Yu could trust the most, so he told them the situation without any concealment.

Including Gao Forensic Doctor, the reaction of the three people was the same as that of Zeng Ke before. They felt incredible. No one could have imagined that Dou Zili, the captain in charge of the criminal police, would suddenly become a major suspect in the island murder case!

However, what Zhao Yu said was well-founded, and he couldn't tolerate them not taking it seriously.

In the end, Ran Tao made a promise to Zhao Yu that he would rush to Doujiazhuang with the speed of a rocket to investigate Dou Zili's background;

Wu Xiumin is still in charge of finding the immediate relatives of the tower guard couple for DNA comparison;

The forensic doctor Gao Facai also volunteered, saying that he would find a way to get the sedative formula used by the little girl's mother to see if it was the same as the sedative in the island murder case?

On Zeng Ke's side, continue to investigate Dou Zili's detailed information to see if there are any new discoveries?

As far as solving cases is concerned, Zhao Yu is already an experienced expert. Experience told him that once the detection has a definite goal, it will not be so difficult to investigate!

Sure enough, as Zhao Yu expected, when they turned their attention to Dou Zili, they quickly found more clues.

Gao Facai, the forensic doctor, was the first to bring the news back. Through forensic tests, he has confirmed that the formulas of the two sedatives are exactly the same.

What's even more amazing is that not only the formula is the same, but even the ratio is exactly the same. In other words, the sedative used by the murderer in the isolated island murder was the same batch of sedative used by the mother of the little fish seller to steal it!

Gao Facai said that this sedative formula used to be circulated in hospitals, but because of its low stability, it was quickly eliminated. If there are still people using it now, it must be prepared by hand. In the case of manual preparation, it can almost be determined that the two are the same batch.

In addition, the forensic doctor Gao had previously checked the drug residues in the body of the deceased in the Gudao case, and suspected that the sedative used by the murderer in the Gudao case showed signs of expiration.

Therefore, they had reason to suspect Dou Zili. It is very likely that when Dou Zili arrested the little girl's mother, he got the sedative prepared by her. Then, he directly used the batch of sedatives to stun the crew on Yongjin Island!

However, the sedative alone is obviously not enough. They can only prove that the sedative came from an arrested thief, but they cannot prove that Dou Zili gave the drug to the victim.

Therefore, if they want to really reveal Dou Zili's true colors, they still lack something more important...
