The car dealer felt puzzled, but he found that after Lu Yunyao said this, all the police relaxed.

The car dealer quickly thought of what this Fairy Yaoguang said: “Master, are you looking for a car?”

Lu Yunyao nodded: “Where is the Toyota GT88 you bought last year.”

The car dealer was very impressed with this car. He spent 50,000 yuan to buy it, and there was huge room for appreciation. The car dealer even thought that it might be upgraded to 300,000 yuan, which was the biggest bargain he had picked up in the past two years.

“Master, is there anything wrong with this car? I bought it formally.”

Lu Yunyao smiled: “All the formalities are in place. The police are grateful that you didn’t touch the car. It’s just that this car is a crime scene, and the police are going to investigate now.”

“Criminal scene?” The car dealer didn’t understand how a car could be a crime scene, but he still fulfilled his civic duty and took people to the warehouse. On the way, he said: “I did clean it carefully. If it was a crime scene, would it be considered a crime?”

Old detective A patted him on the shoulder: “If you knew it was a crime scene and helped clean it, it would be a crime. If you didn’t know, it wouldn’t be considered a crime. I hope you won’t be too diligent.”

The car dealer laughed dryly and said: “I cleaned it quite well. I’ll clean it less thoroughly in the future.”

After removing the car cover, a car that looked brand new was parked quietly.

Usually, when dealing with such a water-soaked car, the seller will be given part of the money first, and the transfer will be carried out after the buyer is found.

Because the car dealer was sure that he could make money from this car, he registered the car directly under his own name. He first took the vehicle license from the car.

When he saw the two words ‘Song Lian’, his spine couldn’t help but feel cold, and his tone changed: “That’s the murderer who killed 7 college students, right? What did he do to this car?”

At that time, the live broadcast of the Public Security Bureau was interrupted only halfway, but it was enough for people to see clearly that the person Lu Yunyao detained was a middle-aged woman.

The dealer remembered that this car was sold to him by an old lady!

The transfer of the vehicle will store the information of the previous person. When the car dealer thought about bargaining with the murderer at that time, his spine was cold: “Am I lucky to be alive? I should have followed his price at that time.”

The young criminal psychologist laughed: “Don’t worry, he deals with so many people every day, he won’t kill them all.”

What Lu Yunyao thought was that if the car dealer followed the other party’s price, it would make Qi Tianshu feel weird, and he might even be worried about his life.

The car dealer was asked to leave the warehouse, and the car door was opened. Using the luminol reaction, everyone could see the sprayed blood sample.

The black ceiling cloth was cut open, and the sponge inside absorbed the blood. The blood had faded to brown, but when it was sent to the laboratory, it was known how much ML of blood this spray would absorb at that time.

Judging from the traces all over the car, the traces here were enough to nail Qi Tianshu’s murder.

In addition, Qi Tianshu also left DNA on the victim’s wife. Even if there was no victim’s body, this murder case was enough to convict Qi Tianshu.

There was a reason why the Public Security Bureau was holding on to this case. Qi Tianshu pursues perfect crime. His mild obsessive-compulsive disorder helped him construct a crime scene that cannot be traced back to evidence at present. Even the murder case of seven college students who make a living has no corresponding evidence at present.

The black rubber gloves, raincoats, and other items were fully burned and have become a completely unrecognizable pile of ashes. The current technical means cannot prove that it contains the victim’s blood information and Qi Tianshu’s DNA information.

These ashes can only be sealed up, hoping that the technology will be reformed and upgraded again in the future so that the information can be separated and captured.

Lu Yunyao gave the people of the Public Security Bureau hope. She said implicitly: “There should be corresponding changes next year, and there may be a way by then.”

After Lu Yunyao confirmed the vehicle, she couldn’t help. She came out of the warehouse to bask in the sun and soon met a familiar person.

This person was He Xiong. When Lu Yunyao connected with [Fairy Yueyue] before, this policeman had appeared on the screen. He also suspected that Lu Yunyao was involved in the case of the kidnapping of the bear child Mumu. Later, Xiong was slapped in the face, so naturally, Lu Yunyao didn’t need to come with him.

He Xiong looked at Lu Yunyao with some entanglement in his eyes.

The leader of the Public Security Bureau brought He Xiong over and greeted Lu Yunyao, saying: “Thank you, Miss Lu, for your advice on solving the case. Miss Lu, have you considered joining the public security system after graduation? Your ability is perfect for solving cases.”

He Xiong said: “I’m sorry, I suspected that Miss Lu was involved in the trafficking incident at the time.”

“It’s human nature.” Lu Yunyao said with a smile: “Officer Xiong is serious and responsible, so he would have such a suspicion.”

An intern under Officer Xiong suddenly rushed over, and he knelt to Lu Yunyao with a plop: “Master, I beg you to help me find my sister. I beg you.”

The leader of the Municipal Bureau glanced at the kneeling person and said to He Xiong: “Hurry up and pull up your intern. What does this look like?”

He Xiong pulled the intern up and said: “What’s wrong with you? Tell me why you asked Miss Lu to find someone. Isn’t there a live broadcast of the abduction? Being a police officer has a certain weighting coefficient, and you will be picked sooner or later, right?”

Lu Yunyao glanced at He Xiong more. He seemed to be pulling people, but in fact, he was reminding the intern to quickly explain his situation.

He Xiong was looked at by such a clear gaze, as if he was seen through, and turned his eyes away uncomfortably.

The intern said with tears in his eyes: “I registered for the special session for human trafficking, but I found one thing. All the special sessions for human trafficking are currently difficult to solve directly by the Public Security Bureau. In several cases of human trafficking, the people ended up abroad.”

“In addition, almost all the people trafficked were alive. I suspect that my sister is dead. There is also a guess that my brother-in-law killed her. He has already obtained a green card and will soon immigrate and will not come back. Even if I am drawn into the next special session for human trafficking, it will be too late.”

This week’s special session for human trafficking was suspended because of Qi Tianshu’s incident. Next week, there will be two consecutive days of special sessions for human trafficking.

For the trainee police, even if he was drawn the next time, there would be big trouble. The current international relations between China and the United States are not good. Once his brother-in-law goes abroad, it may take a long time to extradite him, in terms of current international relations.

The trainee police didn’t want to see such a thing happen, so he knelt to beg Lu Yunyao.

Lu Yunyao said: “I understand, but I have to ask the leaders of the Public Security Bureau about this matter.”

From the trainee police officer’s appearance, his sister was indeed gone, and the connection between the siblings had been broken. Whether to further help solve the case still depends on the opinion of the Public Security Bureau.
