The next morning, when Wang Xue pushed open the door of the interrogation room, Fan Debiao leaned against the chair with his head hanging down and there was no movement. Wang Xue thought he was asleep, so she walked over and pushed him, but found that she had pushed him without any response. Wang Xue pushed him hard again, and Fan Debiao fell down from the chair and lay on the ground.

When Wang Xue looked at it, she saw that Fan Debiao's pupils were dilated, and there was a huge mark on her neck, and her eyes were congested. Wang Xue looked at Fan Debiao's mouth and saw that her tongue had turned purple and black.

When Fan Debiao died, he was strangled to death in the Public Security Bureau. After such a big incident, Wang Xue immediately reported to her superiors. The first ones came were the detachment leader Guo Lei and the team leader Fu Pengchao. When Guo Lei saw that the suspect died in the interrogation room of the Public Security Bureau, he immediately ordered the blockade of the scene and reported to the director. When Mi Yi heard the news that Fan Debiao was dead, he was shocked. An important suspect, an important clue was cut off. Moreover, the person died within the Public Security Bureau. It was hard to believe that if the case could not be solved, it would become the number one scandal within the public security this year. Don’t do it as the director, and don’t think about the position of deputy director. Go home and mop the floor.

Mi Yi immediately ordered a thorough investigation of the case, and all the people who were on duty at the Public Security Bureau last night, who had been in and out of the Public Security Bureau and who had stayed in and out of the Public Security Bureau, were not allowed to leave without authorization, and they would be monitored for twenty-four hours a day until the murderer was found.

The director said, and the entire public security bureau was mobilized. All the police officers on duty last night were controlled and everyone had to undergo rigorous interrogation. Wang Xue also immediately went to the surveillance room to plan to retrieve the surveillance video from last night. However, she found that for some reason, half of the cameras in the bureau were broken, and the interrogation room and the corridors were broken, and only a few at the door were good. However, the Public Security Bureau is a super large unit, with hundreds or thousands of people coming in and out every day. It is impossible for everyone to thoroughly investigate it, which makes the case even more difficult.

When Guo Lei learned that the surveillance was broken, he knew that it was obviously man-made. When summoned the on-duty officer who was responsible for watching the surveillance last night, the person below reported that there was no on-duty officer at all yesterday. Xiao Wu, who was originally in charge of duty, suddenly took a temporary leave because his wife gave birth to a child at home, so no one was on duty in the monitoring room all night. Xiao Wu was likely to be the suspect. Guo Lei immediately ordered and immediately summoned Xiao Wu for questioning.

But after Xiao Wu came, based on his testimony, his family and the hospital's proof, Xiao Wu had never left the hospital last night. So who was the murderer? The case once again entered a dead end.

Through the day and day inspection, almost everyone inside the Public Security Bureau was interrogated, but everyone was either not on duty in the bureau last night or had a certificate of absence. However, the staff on duty had colleagues who could prove each other that they had been together last night. Guo Lei had no choice but to temporarily stop the interrogation of the internal personnel, turn the direction to the periphery, and start to investigate whether there were strangers who sneaked into the Public Security Bureau to commit crimes last night.

However, after one night of investigation, Guo Lei was very depressed to find that there were no vehicles passing outside the Public Security Bureau last night. Jiangnan City is not a first-tier city, but just a third-tier city. And now it is winter again. The temperature is as low as minus one or two degrees at night. There are not many cars on the street, let alone people. The investigation once again fell into a deadlock.

The next morning, in the director's office, the atmosphere was dull and serious. Mi Yi and Wang Huasheng sat on the sofa and kept smoking. Wang Xue and Guo Lei stood in front of them and didn't even dare to show off one.

After a while, Wang Huasheng suddenly said: "You two are dereliction of duty. You know that Fan Debiao is an important witness, but you two didn't send anyone to look at him when you left, which led to his murder. Now that he is dead, the clues are cut off. You guys, how can this case be solved? The leaders of the provincial department all know about this. He has issued a death order to solve all three cases within a week. If it cannot be solved, you, you, and Director Mi, will all be laid off!"

"What, one week? Dad, have you made a mistake? Such a complicated case, how can one week be enough? I think it will take at least one month!" Wang Xue said aggrievedly.

Wang Hua waved his hand angrily and said, "Don't call me dad. We are working now. You and I are superiors and subordinates. I don't have the careless daughter as much as you. An extremely important suspect died in your hands. Do you think, can you bear this responsibility?"

Wang Xue was scolded by her father and almost burst into tears. She pouted and her cigarette was filled with tears: "Yes, Secretary Wang!"

Sitting on the other side, Mi Yi saw the father and daughter who were so angry, and hurriedly became a peacemaker and said, "Hey Xiaoxue, don't be impatient, use your brain more and start your own thinking. Think about it, the criminals dare to kill people in our Public Security Bureau so openly. What does it mean? It means that the murderer is very familiar with our Public Security Bureau. He even knows which corner has a camera and which camera is broken. So, you have to put your skills into our internal personnel. Some things found at the crime scene are very likely to have traces left by the murderer. You must think carefully and seriously."

As soon as Mi Yi said this, Wang Xue suddenly remembered an important clue. She snatched: "By the way, Director Mi, we found a burning filter cigarette at the scene of the crime. This brand is very special and belongs to high-end cigarettes. Among the internal personnel of our public security, there are not many people who can smoke this kind of cigarette."

Mi Yi nodded in appreciation: "Yes, look, right? I just said I wanted to use my brain and you thought of an important clue. Very good. Follow this clue and check it out immediately to see which comrades inside us smoke, and which comrades smoke the kind of cigarette left at the crime scene. Anyone who smokes that kind of cigarette, no matter who it is, will be strictly examined!"

Wang Xue and Guo Lei gave a conditional salute: "Yes!"

The two retreated from the director's office and were about to investigate the internal personnel again. At this moment, a police officer ran to the two of them.
