"I … I … I … I'll check the location of Captain Dou's mobile phone now," Zeng Ke said in a panic. "Leader, you … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You … You …
"Oh …" Zhao Yu nodded and picked up his phone.
If Zeng Ke hadn't reminded him, he wouldn't have thought of this. Yesterday, when he was talking to the little fish girl, Captain Dou had watched them carefully for a long time.
If the little girl's mother was arrested by Dou Zili, then he was likely to know the little girl. Therefore, Captain Dou should have noticed it.
Now that Wu Xiumin was investigating this matter, if she was really targeted by Captain Dou, she might really be in danger.
According to Bureau Chief Wang Chenggang, Captain Dou had gone to deal with the fight at the dock yesterday. However, no one could be sure that he was in the Quliang Police Station!
Thinking that Wu Xiumin might be in danger, Zhao Yu quickly dialed Wu Xiumin's number. But, before the call was connected, Zhao Yu suddenly hung up.
No …
No …
Suddenly, Zhao Yu seemed to have thought of something. He turned off his phone and put it on the table.
"Hey, team leader, it's urgent. What are you waiting for?" When he saw that Zhao Yu hadn't made a call, he became even more anxious.
"That's not right …" Zhao Yu's eyes froze, as if he was thinking about something. After a few seconds, he gently shook his head and said, "Don't worry, Sis Wu will be fine!"
"Nothing? Why? " "That kind of anesthetic mixture is not something that ordinary people can make. Captain Dou must have learned it from the little girl's mother! Obviously, Captain Dou was a major suspect! Leader … "
"Um … Zeng Ke …" Zhao Yu said meaningfully, "Have you noticed that Captain Dou has laid a perfect trap for himself? So, how could he possibly break it with his own hands?"
"Ah? What did you say? "Zeng Ke grinned in surprise.
"It would be great if Captain Dou really did something to Wu Xiumin!" Zhao Yu sighed softly. "But, he's not that stupid! Think about it carefully … Even if we know that Captain Dou is the child of the lighthouse couple! Even if the cigarette butt had his saliva and fingerprints on it! Even if we know that he learned how to use tranquilizers from the criminals that he caught, we can't believe it! But — what can we do? "
"So what?" Zeng Ke was stunned. After thinking for a long time, he finally understood. "Do you mean that even if we suspect him, we can't make him confess?"
"Yes!" Zhao Yu nodded. "Captain Dou is the captain of the criminal police, so he knows all the criminal procedures very well! So, no matter how suspicious we are, even if we interrogate him, as long as he clenches his teeth, we can't do anything to him! "
"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 being alive is very small … "
"Yes!" Zhao Yu then said, "In the vast sea, if Captain Dou hides the body and the murder weapon, we can't find them at all! That's his strongest point! "
"This … So …" Zeng Ke frowned and said, "Captain Dou has nothing to fear now? He's not afraid of us investigating his background at all! So … He just needs to do nothing? Then … "He pondered for a moment, then said," Can we try conventional methods, such as an alibi or something? "
"I don't think that will work!" Zhao Yu shook his head. "I'm afraid that he has prepared everything for such a big trap!
"Motherf * cker, you really can't judge a book by its cover. I didn't expect this sloppy smoker to deceive all of us!"
"Well, this is probably the most bizarre case I've ever seen in my life!" Zeng Ke said as he called out the location of Captain Dou's mobile phone. According to the mobile phone, Captain Dou was indeed in the Quliang Police Station. It seemed that, as Bureau Chief Wang Chenggang had said, he was still dealing with yesterday's dock fight.
"Team Leader, in that case … Is there nothing we can do about him?" Zeng Ke gritted his teeth and asked, "We should at least search his house. What if we can find something like a tranquilizer?"
"No! Before we obtain absolute evidence and have full confidence, we must not act rashly and alert the enemy! Otherwise … "Zhao Yu narrowed his eyes and said," We really won't have a chance! "
As soon as he finished speaking, Zeng Ke immediately realized what Zhao Yu meant. He opened his eyes wide and asked eagerly, "Team Leader, do you have a way to deal with him?"
"What a joke! Otherwise … How could I be your team leader? " Zhao Yu looked at the computer screen and said coldly, "I can't guarantee anything else, but when it comes to setting people up, I'm an expert!
"Come on, Zeng Ke, we're going to be very busy! If the real murderer is not Captain Dou, that's fine. But, if it's really him, I'll make sure that he shows his true colors! "
…
Since they had determined their target, Zhao Yu and Zeng Ke began to work on their plan to solve the case. During this time, Zhao Yu called several people in succession. In addition to Wu Xiumin and Ran Tao, he also called Gao Facai.
These people were Zhao Yu's most trusted people, so he told them the situation without concealing anything.
The three of them, including Gao Facai, had the same reaction as Zeng Ke. No one had expected that Captain Dou, who was in charge of the criminal police, would suddenly become a major suspect in the island murder case!
However, what Zhao Yu said was reasonable, so they had to take it seriously.
Finally, Ran Tao promised Zhao Yu that he would rush to Doujiazhuang at the speed of a rocket to investigate Captain Dou's background.
Wu Xiumin was still responsible for finding the immediate family members of the lighthouse couple for DNA comparison.
Gao Facai also volunteered that he would find a way to get the formula of the tranquilizer that the little girl's mother had used to see if it was consistent with the one used in the island murder case.
As for Zeng Ke, he continued to investigate Captain Dou's detailed information to see if there were any new discoveries.
When it came to solving cases, Zhao Yu was already considered an experienced expert. His experience told him that once he had a definite target, it would not be so difficult to investigate!
As Zhao Yu expected, when they turned their attention to Captain Dou, they quickly found more clues.
The first person to bring back the news was Gao Facai. Through forensic tests, he had confirmed that the formulas of the two tranquilizers were exactly the same.
What was even more amazing was that not only were the formulas the same, but even the ratios were exactly the same! In other words, the tranquilizer used by the murderer in the island murder case was the same batch of tranquilizers that the little girl's mother had used to steal!
Gao Facai said that this kind of tranquilizer formula had been circulated in the hospital, but because of its low stability, it was quickly eliminated. If anyone was still using it, it must have been prepared by hand. So, it was almost certain that the two were the same batch.
In addition, Gao Facai had previously checked the drug residues in the bodies of the victims in the island murder case and suspected that the tranquilizer used by the murderer had expired.
Therefore, they had reason to suspect Captain Dou. It was very likely that when Captain Dou had arrested the little girl's mother, he had stolen the tranquilizer that she had made. Then, he had used that batch of tranquilizers to knock out the crew members on Yongjin Island!
However, the tranquilizer alone was obviously not enough. They could only prove that the tranquilizer had come from an arrested thief, but they could not prove that Captain Dou had drugged the victims.
