Just when Zhang Zhan's family was having dinner, members of the Criminal Investigation Team of Gaohe City Police Station were also having dinner. However, they only ate lunch boxes, and they were working in the police station while holding lunch boxes.

Such a big case happened, and even the city leaders were alarmed. They called and said that they would be solved by one week, which put a lot of pressure on the criminal investigation team. So even when the time came after get off work, everyone did not stop working and went home. They stayed consciously and continued to work and continue to solve the case.

The criminal investigation team leader Jiang Yunye was standing in front of a demonstration board and pondering. On the demonstration board were photos of the scene, as well as a picture of the grimace that was just drawn by the painter based on the description of the bodyguard of the deceased in this case.

The situation of the case was clearly understood based on the after-deduction. At about 2:30 this morning, the murderer climbed over the wall and sneaked into the house of the deceased Fang Xiaoguo, entered the house through the side door, and first knocked out a bodyguard on duty in the surveillance room. He closed all the surveillance facilities in the house and took away the computer hard drive with the videos, and then took away the M9 saber the bodyguard carried with him. Finally, he came directly to Fang Xiaoguo's room, and while Fang Xiaoguo was not awake in his sleep, he used this saber to kill him.

The entire crime process should be no more than ten minutes in total. The murderer moves quickly and has clear goals, and is definitely a veteran of murder. Moreover, this murderer has a high ability to counter-invest. No clues can be left for solving the case at the crime scene and the entire deceased's residence. Not to mention fingerprints, even the footprints he came over the wall were completely destroyed when he left. The only thing that was not damaged was some traces on the wall. However, these traces were not very useful for solving the case, which could only prove that the murderer came in and left here.

According to Jiang Yunye's intuition, he judged that the murderer was definitely not an ordinary person. Moreover, the killing method reminded him of the murder of a gangster in Miaowang Street a few months ago. Both of the dead were also killed by someone's throat cut with a sharp blade, and there were no traces of them available for detection at the scene.

Although this does not mean that these two cases were done by the same person, they have one thing in common, that is, they are sophisticated in the way of committing crimes and leave almost no trace. People with such abilities are either veterans of crimes or professional killers. It is not easy to catch them.

While Jiang Yunye was still pondering, the door of the Crime Team's office was pushed open and two police officers came in. One of them saw everyone eating, and immediately said with a smile: "You all have something to eat? Are there any portions for me and Li Nan?"

Someone immediately replied: "Yes, on the table, one serving per person, go get it myself."

The other police officer who came in was Li Nan, a female policewoman. Today, she ran outside for a day in order to investigate the case. Although she was tired and hungry, once she came in, she didn't have time to care about the issue of eating, but came directly to Jiang Yunye and said, "Captain Jiang, we are back."

Jiang Yunye came back to his senses from his thoughts, turned his head to see the policeman, and nodded and said, "Oh, how about it, have you found anything?"

Li Nan shook his head and said, "In the afternoon, we investigated the movements of Jin Tianya's family in recent days, and there was no notice worth paying attention to. After being injured by Fang Xiaoguo's bodyguard, Jin Tianya has been staying in the hospital these days and has never been to any place. His wife also takes care of him in the hospital all day long and has basically never left the hospital. As for their niece Wu Lan, in addition to visiting Jin Tianya these days, she has basically stayed at home and has rarely seen any records of going out."

After a pause, Li Nan said again: "Captain Jiang, I think today's case should have nothing to do with Jin Tianya's family. If they have the ability to find someone to avenge their daughter, they would not have let Jin Tianya come to the door with a kitchen knife alone. Moreover, I have observed that when they learned that Fang Xiaoguo died, they were all very unexpected and surprised. That expression was not like being fake. They did not know that this happened in advance."

Jiang Yunye nodded after hearing this and said, "I understand. Thank you for your hard work. Let's have a meal first. After the meal, let's discuss the case."

Li Nan then said, turned around and went to the table over there to get his lunch box. A police officer who was eating immediately stood up and helped Li Nan take a lunch box and handed it over. He whispered: "Li Nan, I kept this for you, and it contains the braised pork you like."

Li Nan smiled, took the lunch box and said thank you, and then began to sit down and eat. However, the police officer did not leave, but sat down next to her and said, "I also think this case has nothing to do with Jin Tianya's family. If you can kill Fang Xiaoguo so easily, how can you get in touch with ordinary citizens? Team Jiang asked you to investigate the trends of Jin Tianya's family, and I think it's a waste of time."

Li Nan smiled when he heard this, and lowered his head and ate the meal, saying, "The captain has the captain's consideration. Would he not know what you said? Besides, no matter what, Fang Xiaoguo was killed at this time, and the Jin family is suspected of being unable to escape. If we don't investigate carefully, how can we rule out the possibility of their crime?"

The policeman had nothing to say. At this moment, another policeman came over and whispered: "I said, do you think this case can be solved in a week? There are too many people who want to kill Fang Xiaoguo. I will investigate one by one. When will I find out? Also, a scum like Fang Xiaoguo deserves to die. I feel really uncomfortable being busy with people like him."

The police officers around Li Nan also said with a similar feeling: "That is, Fang Xiaoguo had committed so many cases before, but the superiors never said so harshly that they would solve the case within a time limit. Now it's his turn to die, and it has become a major case that the city focuses on. It's really not worth it to have us so tired for such a scumbag!"

Most of the members of the serious crime team have such a worthless feeling, and Li Nan has it, but she is also a policeman after all, and she still has the least organizational discipline. So she raised her head and glared at the two colleagues, saying, "What are you complaining about? Isn't it the responsibility of our police? Fang Xiaoguo is a scumbag, but he cannot use means other than the law to deal with him. Killing people is a violation of the law, and if you break the law, you will be arrested. What's there to be long-winded? Speak less nonsense and have a meal!"

Although Li Nan is not a leader in the Crime Team, she is the only female policewoman in the team and looks pretty good. Many unmarried male police officers are all very interested in her. These two police officers happen to be Li Nan's suitors, so when she was scolded by her, she immediately shut up and lowered her head to eat, and she never dared to complain anymore.
