Xu Yao assigned another task to Mo Xiaoqing:

"Mo Xiaoqing, I have an important matter for you. I heard from the doctor at the hospital that Huang Zhixiang's condition is not good. She has nightmares every night and hides in the quilt during the day and does not communicate with anyone. We originally planned to get clues from her, but considering her physical condition, we will not take a tough questioning approach, but use indirect means. Do you understand what I mean?"

Mo Xiaoqing stood up from the stool and answered with full energy, "Yes, I understand. Captain Xu wants me to communicate with Huang Zhixiang as a friend and get information from the side."

Xu Yao gave her a knowing look and continued, "Have your forensic department and technical department come out with the report on the dismemberment scene?"

"Almost all of them have come out. After testing, we confirmed that the blood in the body-crushing room was human blood, from the deceased Xiang Xinyi.

Two sets of fingerprints appeared at the scene, one set was confirmed to be from the deceased, and the other set was compared and found to be from the reporter Huang Zhixiang.

Regarding the three sets of footprints, the one at the door is very consistent with the sole prints of Huang Zhixiang's shoes sent by Team Xu, so it can be confirmed that they were left by Huang Zhixiang's shoes.

As for the two sets of footprints on the corners of the chemical barrels, we can only confirm that one set is female and the other is male.

However, the hair that Team Xu took off the wall at the time was found to be Xiang Xinyi after testing. From the set of female footprints, it can be seen that she was standing with her back against the wall at the time, so it can be inferred that the female footprints came from the deceased Xiang Xinyi."

Xu Yao interrupted, "So the remaining set of footprints is very likely to be left by the deceased?"

"Yes, it is very likely."

A police officer at the meeting exclaimed, "It seems that we have really encountered a highly intelligent murderer this time. He cut off the victim's head when dumping the body, probably to cover up the identity of the deceased. Our national DNA database is not perfect yet, and we cannot confirm the identity of the deceased through DN comparison.

Moreover, there is only one set of footprints left at the crime scene, not even fingerprints or very subtle physical evidence of hair.

Captain Xu, could such a highly intelligent crime really be committed by a madman? Even if he has accomplices, how can a madman listen to the arrangements of normal people?"

Xu Yao put his hands on the desk and said calmly, "This is not unreasonable. Maybe."

Every time he thought about the problem, he couldn't help but take out a cigarette from his pocket, lit it, and said, "I later sent someone to investigate carefully. This Deng Yaohua is not a mental patient in the strict sense, but has schizophrenia."

As soon as Xu Yao said this, the whole conference room began to discuss it. After listening to it, Mo Xiaoqing suddenly realized it and couldn't help but exclaimed, "Oh, yes, I remember. At that time in the room, the Deng Yaohua who just came in and the Deng Yaohua who came in later behaved like two completely different people. Captain Xu meant that another personality of Deng Yaohua killed the twins, and he also found an accomplice."

"It is very possible, but all of this is just speculation. We have to wait until Deng Yaohua and his accomplices are arrested and brought to justice, and then the truth can be revealed through interrogation. You know, investigation is about..."

Before Xu Yao finished speaking, the people in the conference room answered in unison:

"Evidence."

"Very good, no more nonsense, everyone should work together. Go go!"

Xu Yao began to arrange the work in an orderly manner, "Old Wang, send two teams to continue to watch the vicinity of Deng Yaohua's house, and the other team will keep an eye on Deng Fu's family at all times."

The battle started, and the battle began.

The police officers came out in droves, dividing the work and cooperating.

At twelve o'clock in the morning, the report came that there was no movement near Deng Yaohua's house.

Li Fu's family. Li Fu's wife went out to buy groceries at 7 o'clock, and then stayed in the mahjong hall.

Li Fu stayed in the pork stall and went to the bathroom twice.

Li Fu's son Li Dexing was playing a game in the basketball court of the community in long clothes and long pants.

The situation on Mo Xiaoqing's side was not optimistic either. Huang Zhixiang curled herself up into a ball, hid in the quilt and refused to communicate.

Liu Xiaobo led a group of police officers to knock on doors and check door to door along the area marked by Xu Yao, and found clues.

A middle-aged woman said that when she went out to take out the garbage, she found a set of brand-name sportswear in the vegetable garden on the side of the house. The

middle-aged woman also said that even her 18-year-old son liked the sportswear very much, and most young boys now have one.

Liu Xiaobo confirmed that the clothes worn by the man in black that night were very similar to this one.

Xu Yao asked Liu Xiaobo to send him the location of the middle-aged woman's home and to take a careful photo of the sportswear and send it to him, not missing even the details.

Then he quickly sent the sportswear to the technical department for inspection.

Xu Yao then began to work. He first scribbled on a paper map, and then asked a computer expert from the technical department to hack into a QQ space.

Suddenly his eyes lit up and he exclaimed loudly: I know who the black man is?

Xu Yao asked Liu Xiaobo not to move and would drive to pick him up in 20 minutes.

After getting in the car, Liu Xiaobo asked in confusion, "Boss, where are you taking me?"

"To catch the man in black!"

Liu Xiaobo exclaimed, "Captain Xu, you know who the black man is, awesome!"

"I can't say I'm 100% sure, but at least 99% sure."

The black jeep drove into an old neighborhood and stopped outside the iron fence of the basketball court.

The police officer who was watching in the dark saw Captain Xu get off the car and hurried over to report the situation, "Captain Xu, we've been watching him."

"Okay, thank you for your hard work, you guys should withdraw first.

A mere high school student naturally does not require much police force. Xu Yao jumped into the basketball court and interrupted this unique game.

Before Li Dexing could react, Xu Yao grabbed Li Dexing's arm with lightning speed and pushed him down on the basketball court with a backhand. He took out a pair of handcuffs and handcuffed him, "Let's go, take him back for questioning."

Li Dexing was not convinced at all and shouted loudly, "Why did you arrest me? Do you police want to abuse your authority!"

Xu Yao got angry and punched him, "Why did you arrest you? That's a good question, you should know better than any of us."

Xu Yao's eyes were extremely intimidating, and Li Dexing's tone became hesitant.

"I...how do I know? I didn't break the law!"

"Whether it's illegal or not, you know it very well. You will know everything after the interrogation. Take him away!"

Liu Xiaobo was also confused. In fact, up to now, he still couldn't figure out how Captain Xu was sure that the man in black was Li Dexing.

A detective is a detective. His brain circuits are naturally more powerful than those of ordinary people.

The interrogation was scheduled for 3:30 pm. Before the interrogation began, Xu Yao stayed in the conference room and asked a young police officer to help him.

The blackboard was filled with dense writing. Xu Yao was facing the blackboard in deep thought. Suddenly, he said, "Pen, give me a pen."

A pen was handed to him. Xu Yao looked at it carefully and was immediately furious. "What did you do? You asked me to write on the whiteboard with a white carbon pen?!"

A trembling voice sounded, "I'm sorry, Captain Xu?"

and a red pen was handed to him.

Xu Yao said unhappily, "White."

He couldn't help but mutter in his heart, why are the brains of young police officers nowadays getting worse and worse?

"Now help me retrieve the surveillance footage before the twins disappeared."

Then two minutes passed, five minutes passed...

There was no response.

Xu Yao turned his head and saw the young police officer sitting in front of the computer, touching the mouse with trembling hands.

When he looked up and saw Captain Xu's angry eyes, he stammered, "Captain Xu, I'm sorry! I haven't found it yet."

Xu Yao asked him to stand aside, and he decided to do it himself. After struggling for a long time, he still couldn't find the surveillance video, so he shouted,

"Mo Xiaoqing!"
