It turned out that because this case is of great importance, during the investigation, the special investigation team deliberately restricted the investigation authority. The police were only assigned different tasks, but they could not fully understand the entire investigation.

Therefore, not many people know that the special commission team is investigating the lighthouse incident. Moreover, although locals know about the lighthouse murder case decades ago, they are not familiar with the name Liu Caiyun.

Therefore, the police asked this question only after Zhao Yu claimed that Dou Zili's mother was Liu Caiyun.

Zeng Ke understood what it meant, so he quickly introduced the whole story of the lighthouse case to several police officers. When they learned that Liu Caiyun was the wife of the tower guard, he finally showed surprise.

"Ah? No way? It's that... that..." An older policeman had a deep memory of the Lighthouse case. After hearing this, he hurriedly looked at Dou Zili and asked in surprise, "Captain Dou, is this... true? Auntie is... Liu Caiyun!? And you..."

"Hmph! It's true and fake, it's true!" Zhao Yu said to Dou Zili, "Captain Dou, you should be very clear in your heart. Since I decided to investigate the Lighthouse case, you should have thought that sooner or later I will find out about this matter!

"Don't think that your mother has no household registration, and the information in Doujiazhuang shows that both your parents have died, so we will not check it down!"

What Zhao Yu said is not a false statement. Although he is setting up a trap, he is not aimless. What he said before was that waiting for Wu Xiumin and Ran Tao to take their place was actually waiting for this important result.

Despite their age, the police station archives still contain photos of Liu Caiyun from that year. When Wu Xiumin and Ran Tao met Dou Zili's mother, there was no need for DNA at all. They just need to compare the photos to confirm her identity.

Moreover, Wu Xiumin is a psychologist. When she and Ran Tao entered Dou Zili's house and had a "happy" chat with the old lady, she became more convinced that the old lady was Liu Caiyun who had been missing for decades!!!

This news is undoubtedly the most important. Only by confirming that Dou Zili's mother is Liu Caiyun, all their previous assumptions and speculations can be established.

Once you confirm your identity, you will have a motive for murder!

"Dou Zili, don't you admit it?" Zhao Yu sneered, "You are the child of the tower guard couple back then! Cai Xiangbin killed your father and raped your mother. Now, Cai Xiangbin's nephew Cai Jinda has made up an unreliable script to slander your parents. You can't swallow this, so you have to kill someone to retaliate!"

After Zhao Yu finished speaking, the whole audience was quiet, and the air seemed to solidify. Everyone's eyes looked at Dou Zili standing in the center of the venue.

"Hehe...hehe...hahaha..." Unexpectedly, after a few seconds of silence, Dou Zili actually burst into laughter, making people feel goosebumps.

"Team leader Zhao, I admit that it's mine that I didn't report this matter!" Dou Zili said with a strange look on his face, "But you don't have to arrange me like this, right? I'm saying that I'm the murderer, but it's a bit over it? Even if my mother is Liu Caiyun, even if Cai Jinda slandered her, I don't necessarily have to kill anyone? Those are six dead, and I can't afford this charge!"

"You still dare to argue!" Zeng Ke said, "Actually, your target is only Cai Jinda, but you had an accident when you killed him! So, you might as well just do it and kill more people!"

"Ah? This...accident?" The old policeman was incomprehensible.

"Sir, sir, please, please..." At this time, the wet policeman ran in with his cell phone and said to Zhao Yu anxiously, "Can you answer our Director Wang's call?"

"I'm not available! Are you going to confess immediately if you haven't seen the prisoner?" Zhao Yu waved his hand and said in an orderly tone, "This is it, you might as well turn on the hands-free and let your Director Wang and your colleagues in the police station listen together!"

"Team Leader Zhao! It's appropriate to joke!" Dou Zili shouted in a hurry and said angrily, "Please use your brain and think about it carefully. Is it okay? I am the captain of the criminal police. Although I have no great achievements, I still understand the minimum principles and principles! Even if I want to seek justice for my mother, I can have many ways, such as...

"For example, I can take legal measures or something!"

"Take legal measures?" Zhao Yu shook his head, "If your mother is not afraid of being exposed by the media, why do you have to hide your identity for so many years?"

"Really..." Dou Zili said with an innocent look on his face, "Why don't you believe me? OK! OK! Even if I don't want to expose it, I don't want to take legal measures! Then I have a solution!

"Everyone in Qu Liang knows that those who run the boat must give me face. As long as I give orders, let alone a small crew, no matter how big the film team is, they can still be bombarded away! But..." Dou Zili clenched his fists and said, "I can't kill anyone?"

"Okay, Team Leader Zhao, I know if I'm wrong? I really don't want to hide it from you in this matter!" Dou Zili said repentantly, "It's really not easy for my mother to hide her identity for so many years. I really don't want to involve her because of the case and then sprinkle salt on her wounds again! It's wrong to conceal the truth. Please have a lot of it, don't play with me, okay?"

Dou Zili's words were immediately effective. The police officers who had already doubted him were persuaded again, looking at Zhao Yu with almost begging eyes, wanting to plead for him.

"Beautiful! Beautiful!" Zhao Yu clapped again and nodded, "Captain Dou is really a good skill. It's really a talent to be a mere criminal police captain! It seems that you have to be a little serious with you, and you will know how many eyes Prince Zhao has! Zeng Ke, close the door and let the dog go!"

What!?

Everyone was stunned and retreated one after another.

Zhao Yu hurriedly raised his arm and added: "Just kidding, just relax the atmosphere! Hahaha... Zeng Ke... big screen!"

"Oh!" Zeng Ke agreed and immediately projected the information of the little girl selling fish onto the big screen.

"Please look everyone!" Zhao Yu pointed to the screen and introduced, "This person is a female thief who was arrested last year. This person used a manual-made drug to faint the wealthy businessman's family, and then stole it. In the end, he was caught by our amazing Captain Dou!

"We have verified the formula for that drug, guess what?"

"What's wrong?" Seeing that the police officers were stupid, Zeng Ke had to make a fuss for Zhao Yu himself.

"Hehe!" Zhao Yu switched the screen, "The formula of this kind of drug is exactly the same as the drug that was dizzy for the victims of the Isolated Island murder case!!!"

"Oh?" The police officers then understood what Zhao Yu meant and were speechless again.

"Okay, since we have found such an important clue, we should chase it!" Dou Zili waved his hand and signaled, "I remember that female thief, she absolutely can't make it herself, and she must have accomplices. So, as long as we find her accomplices, we can find the clues?"

"Haha, if the daffodils don't bloom, you're going to pretend to be garlic for me!" Zhao Yu pointed at Dou Zili with his hand, "The person who stole the female thief's pill and then used it to make the crew members confused is you!"

"How can I tell this?" the police officers were shocked.

"Isn't this nonsense? What do I do with the thief's pill?" Dou Zili shook his head.

"Who knows what you keep for? You must not think of good things in your mind?" Zhao Yu complained, "The forensic doctor has tested that the drug in the crew is in the same batch as the female thief, and it has expired.

"If it was done by the female thief's accomplice, there is no need to use expired products, right? Besides, according to our verification, the female thief used to be a pharmacist in a county hospital, and she had no accomplices at all! But you said just now that you know her?"

"She can't say that she doesn't have accomplices? This is ridiculous..."

Before Dou Zili finished speaking, Zhao Yu raised his eyebrows and said hard: "Don't worry, I didn't point at you and would confess my guilt easily. We have just started! Let's talk about cigarette butts! We found many Hongmei brand cigarette butts near the crime scene, which are the signs that Captain Dou often smokes!"

"Tsk, there are so many people smoking!" Dou Zili was helpless, "It might be that I left there?"
