The conference room was silent and dull, and the expressions on everyone's faces were extremely solemn.

Director Wang cleared his throat and continued: "As far as I know, there has never been such a major criminal case in Yangcheng since the founding of the People's Republic of China. The occurrence of this case is not only a major test for your front-line case-handling personnel, but also a major test of our leadership ability at the decision-making level. We were given a one-month deadline and asked to crack the case and catch the murderer within a month. Here, I would like to say to you that I believe that our public security officers and police officers are invincible swords, and as long as the sword is unsheathed, it will be invincible and invincible. As long as we show the dauntless spirit of not being afraid of hardships and hardships, and devote ourselves wholeheartedly to the investigation of cases, we will certainly be able to unite as one, overcome difficulties, and achieve final victory. I have faith in you. ”

Speaking of this, Director Wang's tone was no longer as depressed as before, but became more and more passionate. Liu Panneng was inspired by his words, and his mind was full of belief in victory. He couldn't help but raise his eyes and look around, and found that everyone, including Liu Pancheng, was full of fighting spirit at this moment under the encouragement of the director, and everyone's eyes were also firm and resolute.

"Alright, I'll stop here if I want to boost morale." The director instantly calmed down and regained a steady tone, "I know that time is very precious to you now, and you must race against time to devote yourself to solving the case, so I won't take up more of your time to talk nonsense." Next, let Team Liu sort out and summarize the current progress of the investigation of the case with you, and then we will discuss and deploy the next work tasks. The director turned his face to Liu Pancheng, "Team Liu, I'll leave it to you to preside over below!" ”

"Okay." Liu Pancheng exchanged a look with the director, nodded, and said, "Before getting into the main topic, I want to explain that since it has been raining from the time of the case to the present, the rain has brought great difficulties to the scene investigation and evidence collection, and there is not a lot of key evidence that we can collect at present. ”

Liu Pancheng paused, cleared his throat, raised his voice a few points, and continued: "Now, let me first talk about the situation of the three victims. After further forensic examination, the cause of death was basically the same as the preliminary judgment at the scene, and all three people were hit hard in the brain with blunt objects, causing them to die on the spot. Judging from the injuries on the victim's brain, the murder weapon was similar to a baseball bat or a hammer. At present, the comrades of the Criminal Science Institute have taken some material samples from the victim's wounds, pending the results of further analysis. ”

After Liu Pancheng introduced the situation of the three victims in one breath, he turned to the director of the criminal department present and asked, "Does the criminal department have any additional explanations?" ”

The person who was asked shook his head slightly: "This is the situation at the moment, there is nothing further to add." ”

"I'd like to add something here." Director Wang suddenly interjected at this time, "Due to the limited conditions for handling cases in our sub-bureau, after asking for instructions, the Provincial Public Security Department specially appointed an expert in criminal identification to assist us in handling the case. On behalf of the leaders of our sub-bureau and all the cadres and police officers involved in this case, I would like to express my sincere gratitude to him for being able to participate in the investigation of the case in his busy schedule. ”

"Wang Ju, don't say that, everyone is for work. The nature of this case is extremely bad, and the leaders of the provincial department attach great importance to it, and we also want to help you to solve the case as soon as possible and bring the criminals to justice. The technical expert sent by the provincial department immediately said modestly.

"We continue to analyze the case." Liu Pancheng brought the topic back to solving the case, "Now let's talk about the situation of the vehicles involved." It was confirmed that the white Jinbei van parked at the scene was indeed a cash transport vehicle of Xinfa Bank. The car drove out of the administrative building of the Xinfa Bank near Yanfei Road at about half past seven this morning, which is commonly known as the 'big courtyard' inside the bank, and was originally scheduled to deliver the cash and treasury bonds to the two business offices in the new and old towns, respectively, before the bank opened for business, but it was robbed shortly after leaving the 'big courtyard'. ”

"At present, we have verified that a piece of glass on the door of the vehicle involved in the case was smashed and that the tool used should be the same tool used to kill the three victims, an object similar to a baseball bat or a hammer. However, given that the glass of the cash truck is specially treated, we prefer the latter. In addition, the vehicle involved in the case should have been hit during the time period of the crime. The rear right rear of the vehicle had shattered the lamp shade and fragments of the lampshade were collected on the ground at the rear of the vehicle. At the same time, the comrades of the Criminal Division also found traces of peeling paint in the depression where the body was impacted. When identifying the paint residues, the comrades of the Criminal Division identified two kinds of white paint. After further comparison, we preliminarily deduced that one of the white paints was likely to come from the vehicle that caused the accident. However, our case handling conditions here are limited, and we cannot analyze these two white paint samples, so we need to use the identification technology of the provincial department. The final sample analysis results may take some time. Once we have the results of the analysis, perhaps we can start with the paint composition and find out the make and model of the vehicle that caused the accident. ”

"Team Liu, I'm sorry, I'll interrupt." The technologist politely interrupted, "You'd better not expect too much from this. First, the samples extracted are very small, and there may be no effective substances at all; Second, even if the extraction is successful, it does not mean that the case can be solved. ”

"Why is that?" Wang Kui asked puzzled.

"If the car is damaged or repainted, there's a good chance we're not picking up the original paint from the car. Even if we can analyze the substances contained in the paint, we may not be able to trace the make and model of the car. "There are so many uncertainties. If we follow this lead as a key piece of evidence, it may delay time. ”

"We'll take your suggestion seriously." After Liu Pancheng pondered for a while, he continued, "In addition, according to the identification of the damage to the vehicle and the location of the collision, we ruled out the possibility that the vehicle that caused the accident was a small car, and preliminarily identified it as a vehicle such as a van. In addition, judging from the tire marks left at the scene, the speed of the two cars should not be very fast at the time of the collision, and the brake marks are not long. Considering that it was a rainy day at the time, the two cars should have collided at close range. Liu Pancheng adjusted his sitting posture and tapped his fingers twice on the tabletop, "However, I want to focus on the tires here." When the comrades of the Criminal Division Institute analyzed and compared the tire marks at the scene, they found that the tire marks of the two groups were exactly the same, but they differed in the degree of wear. Based on this, they determined that the two sets of tire marks came from two cars. In other words, the vehicle involved in the accident and the vehicle involved in the case at the scene used the same brand of tires. At present, we have the brand of tires used in the vehicle involved, which is an important clue for us. Wang Kui, you arrange the personnel to do a survey of the vans on the market now to see which brands of vehicles use this tire. ”

"Okay." Wang Kui, who was named, immediately responded, and then lowered his head and wrote in the notebook in front of him.

"Team Liu, can I ask a question?" The deputy director of Qu, who came with Liu Panneng, raised his hand in front of him and said loudly.

Liu Pancheng immediately turned his gaze to him and said in a deep voice: "You ask!" "Why are we chasing the vehicle that caused the accident now? Is there evidence that the car was the perpetrator's means of transport? ”

A question from Deputy Director Qu caught the attention of everyone present, and they all focused their eyes on him. For a while, Deputy Director Qu looked a little embarrassed, and subconsciously lowered his head. In fact, he knew very well in his heart that in his capacity, he would not have had the right to speak at a meeting of this level. The only purpose of his coming here is to receive the task and follow the arrangement, so that when he returns to the office, he can assign work and implement the tasks at the meeting.

And Liu Panneng, who was sitting next to him, also looked a little unnatural under the eyes of everyone. He moved his upper body uneasily in his seat, and glanced at Deputy Director Qu out of the corner of his eye, a little reproaching him for speaking casually. Liu Panneng is a person who doesn't like to be in the limelight, and he also doesn't like the style of his subordinates who deliberately highlight themselves to attract attention.

After everyone glanced at the deputy director, they turned their eyes back to Liu Pancheng's face, waiting for him to respond.
