While the manhunt is in progress

Chapter 597
When Song He saw a pile of Luo Province case information appearing on his desk, the blood vessels in his forehead jumped suddenly. He immediately closed his eyes and took a deep breath, fearing that he could not hold back and slap Qi Weigang's seemingly honest and honest face. A cunning face.

After a while, Song He opened his eyes, with fire flashing in his eyes, as if he was about to burst into flames at the next moment: "Old Qi, I have something I don't know whether to say or not."

"Talk!" Qi Weigang waved his big hand, and his big face forced the sparks in Song He's eyes: "As long as you can get these cases down, you can say that the sun belongs to your family!"

Song Hewen paused, gritted his teeth and said, "You are a living bandit!"

Zhou Kai and others rarely saw Song Heneng being deflated, and they burst into laughter.

"Well, that's right! I'm a bandit." Qi Weigang also laughed, and simply accepted the title of bandit, and then pushed the case information in front of Song He: "Come on, Master Song, it's been a hard day these days." is you."

Song He was speechless when he saw this, looked at the case materials in front of him, and couldn't help but feel sad for the busy life in the next few days.

If Song He could calmly handle Lu Jing's extortion after bargaining, then Qi Weigang's behavior of blocking the door and robbing made him feel even more urgent.

After all, Qi Weigang can only stay in Yucheng for a week. Now that these cases are added to the daily communication content, the arrangement of time and content will inevitably become more and more compact.

However, what pleased Song He was that Qi Weigang only said that he had ideas for solving the case, and did not need to catch the suspect in one step.Otherwise, let alone a week, I'm afraid I won't be able to finish these cases in a month.

"Old Qi, although you want to build your reputation, don't expect to become fat in one bite." Song He hastily flipped through the case information, took out one and threw it to Qi Weigang, and said seriously:

"I'll help you go through this case from beginning to end, and give you ideas for the rest, and you can go back and figure it out yourself."

Qi Weigang glanced at the case at the end, smiled with bright eyes, and patted Song He's shoulder vigorously, his voice was thunderous: "It's still Song Daoyi! I didn't say anything! When you come to Luo Province in the future, you will say hello, and I will definitely be the most considerate of you." all!"

Faced with Qi Weigang's unscrupulous personality, Song He was also helpless. After glaring at him, he stopped talking and began to carefully analyze the piles of case materials, allowing Zhou Kai and Wu Xuerui to start studying and investigating according to the process.

Five days later, after cramming time to finish the study tour, Song He and others gathered with Qi Weigang in the meeting room of the case center and began to discuss several cases that Qi Weigang had brought from Luo Province.

"I have to say that the cases selected by Lao Qi are still very representative." Song He glanced at the smug Qi Weigang unhappily, and continued: "Most of them are old unsolved cases. What is being discussed is the case that has been delayed the longest.”

Song He said that he used the projector to enlarge the materials that he had worked so hard to sort out, and the case data that appeared on the projector also made everyone understand immediately that this was a murder that happened 25 years ago.

"The victim of this case was a woman, and the time of death was between one and three in the morning." Song He stood on the podium, showing a sense of familiarity in his gestures: "The crime took place in an urban area. In the sparsely populated suburbs on the edge, there are no people living within a two-kilometer radius."

"So, this makes it impossible for the deceased to be heard even if he shouted for help when he was killed. At the same time, this also means that the probability of witnesses is almost zero."

"However, there are a few doubts here. One is that the deceased's job is a typical nine-to-five job, and she often goes home as soon as possible after get off work. What made her suddenly change her itinerary without notifying her family in advance."

"Also, as far as the vertical distance between the crime scene and the nearby road exceeds 100 meters, did the deceased appear there actively or passively? In these two cases, how did they appear there?"

"Under the level of criminal investigation at the time, it was difficult to obtain answers to all the above questions. So the real breakthrough point of the case lies here."

Song He changed a projection while talking, but it was a report and a photo of the scene.

"The traces at the scene show that the murderer violated the victim before killing him." Song He pointed to the report and said, "This also caused the murderer's biological information to be left at the scene."

"I took a look. The murderer's biological information is well preserved, so this will be the key evidence for us to identify the real murderer."

Qi Weigang raised his hand and said: "I know that biological information identification can directly identify the murderer, but no matching results have been obtained in the past few years. Even with the fuzzy matching method of family gene comparison, no clues have been found so far."

"I know." Song He nodded, turned another page of the projection, pointed to the photo above and said, "So we need to narrow the scope of investigation as much as possible, if we can limit the suspects to a general range, We're one step closer to winning."

Qi Weigang nodded, looked at Song He excitedly, raised his hand in a gesture of invitation: "Please start your performance!"

Song He was frustrated for a while, took a deep breath and continued: "This case has been dragging on for more than [-] years, and the difficulty is not ordinary. Fortunately, the investigation team back then left enough photos of the scene to provide us with some help .”

"Look at this first. This is the clothes worn by the deceased. Please look at the buttons of this shirt."

The photo shows a white blouse. Although it looks a bit old now, it was a very fashionable and popular style back then, and most people are very determined to buy such a valuable blouse.

And when everyone focused their eyes on the buttons of the shirt, Wu Xuerui frowned suddenly: "This style of buttons is not easy to untie."

"That's right." Song He said and zoomed in on the photo, but saw that the button on the shirt was a round shape. At first glance, it looked like a circle, but when you looked closely, you could find that it was more like a hexagon. .

"It was a fashion back then, but it was difficult to undo the buttons." Song He continued to zoom in on the photo: "And as we all know, the button positions of women's shirts and men's shirts are opposite from left to right."

"But you see, the buttons and buttonholes of this shirt are all intact. In other words, the shirt was not torn apart violently, but was undone button by button by the murderer."

As soon as he finished speaking, there was a burst of whispers in the conference room.

Song He continued after everyone's discussion was over: "As far as the current situation is concerned, among all similar cases in the country, there are very few who can unbutton the buttons in an orderly manner like the murderer."

"And this phenomenon shows that the murderer has good living conditions and growth environment, and even has a corresponding educational background and social status. At the same time, when the murderer did it, the deceased either lost the ability to resist, or did not resist at all. .”

"If the person loses the ability to resist, then the murderer must have the ability and tools to move the victim. If there is no resistance, then the relationship between the murderer and the deceased is extremely close, and his true identity will inevitably be limited to a very small range. .”
