Don't show affection at the crime scene

Chapter 17 Murder Weapon
Luo Shixian's eyes lingered on Su Zhiqian's face for a moment, then immediately returned to the projector, and said, "Jin Min doesn't trust Zhao Tianyong from the movements of turning her head several times. The key to the problem lies in the relationship between the two." According to the interviews conducted by the colleagues of the second team for several weeks, the relatives and friends of the victim said that the deceased kept himself clean and had a certain sense of crisis. The autopsy report given by the forensic doctor proved that the deceased did not drink too much that night, excluding the possibility of losing his mind after drinking. This information can tell us that Jin Min and Zhao Tianyong know each other but are not familiar with each other, and may have met several times."

"Well..." An Ningshuang nodded, and another confusion appeared in his mind, and asked: "Boss, the accident happened around two o'clock in the morning. It was so late, and a man and a woman who were not familiar with each other met in a bar. According to common sense, they There is only one possibility that they will leave at the same time!"

Indeed, the bar is an excellent place for an affair, and the men and women who come here always have impure thoughts.Under the influence of alcohol, it is normal for men and women on the dance floor to indulge themselves, let the explosive songs dominate their minds, and look for prey for tonight's spring festival.

Human nature likes novelty. Many people have completely different personalities from those in front of them and those behind them. We cannot rule out the possibility that Jin Min is also this kind of person.

"First of all, we need to confirm whether Zhao Tianyong, Zhang Ying, and Jin Min knew each other. Tomorrow, we will visit the relatives and friends of the two victims to see if anyone knows their relationship." Luo Shixian did not deny An Ningshuang's intention Point of view, and tell the way to confirm the two people's conjectures.

"Okay." After An Ningshuang responded, she turned her head to look at Su Zhiqian, and said, "Doctor Su, does your coming here mean that you have finished reading the materials!"

"Yes." After Su Zhiqian replied, she sat next to An Ningshuang very naturally.

"Forensic Doctor Su, did you find something?" Luo Shixian turned around and stared at her with short hair.

Su Zhiqian nodded, it's no surprise that he guessed the purpose of his visit, after all, Luo Shixian is an expert in this area.Thinking about it this way, she said: "We analyzed the case before and concluded that Gu Manman's case may be the murderer imitating the crime based on Zhang Ying and Jin Min's death, because the two deceased who were killed last month are related to Gu Manman's case. , There are certain differences in essence. However, I compared the photos of the deceased taken from the scene, and found that the wounds of the three deceased were similar in shape, and they should come from the same murder weapon."

"Su Forensic Doctor, you mean that the three cases were committed by one person." Luo Shixian had a look of surprise on his face, summarizing the meaning of Su Zhiqian's words.

"Many details of the three cases were handled differently. This shows that the murderer tried his best to conceal the difference between the first two cases and the Gu Manman case. However, the murderer ignored one important point. The wounds of the deceased were not Liar." Su Zhiqian explained her judgment to the two, and then she said: "In addition, the murderer used a common fruit knife. According to the wound conditions of the three deceased, the blade length is 18mm. The knife is about 20 centimeters long, and Zhang Ying and Jin Min’s fatal neck injuries judged that the angle of the knife edge is between 80 and 90 degrees. Among them, judging from Gu Manman’s amputated lower limbs, the murderer should have used an ax as a tool, the murder weapon The head is about 380 to 385 mm long, the blade length is about 80 to 85 mm, the length of the striking surface is about 40*20 mm, and the weight is around 500 grams."

When An Ningshuang heard this, her eyebrows hung down, and she sighed: "Fruit knives and axes are very common tools in daily life, I'm afraid it's not easy to lock the target."

"That's right! I'm also worrying about this!" Su Zhiqian nodded in agreement, and immediately added: "However, things are not that bad. The murderer can control each knife to two centimeters, which shows that his knife skills are very good. Accurate, it takes more than five years to practice such an ability."

"What you said makes sense." Luo Shixian continued the topic. After thinking for a while, he said, "Doctors are good at using scalpels. In addition, chefs often need to use knives. Of course, this alone cannot It is ruled out that the murderer is suspected of other occupations."

"Yes." Su Zhiqian replied.

Luo Shixian thought for a moment, then continued: "Zhao Tianyong is a mobile phone store operator, does he have such knife skills?"

"I'm afraid I have to ask Xu Ruyi about this." Su Zhiqian replied.

An Ningshuang patiently listened to the two people's questions and answers, and suddenly seemed to think of something, and hurriedly said: "Boss, Zhao Tianyong is a gangster, and he must have done a lot of things with guns and knives."

"In this case, forensic doctor Su also witnessed a person. It is not ruled out that he did the trick. Zhao Tianyong went to lure the three victims." Luo Shixian said.

As a people's policeman, you must not let go of any clues related to the case.

"Understood. Boss, when we ask Zhang Ying and Jin Min's relatives and friends tomorrow, this person's information cannot be ignored." An Ningshuang wrote down this point.

"Yes." Luo Shixian replied, "Continue watching Gu Manman's video."

"Okay!" As soon as An Ningshuang's voice fell, she pressed her finger on the mouse, and the screen switched quickly.

Seeing that they were about to watch the next video, Su Zhiqian focused on the projector, and the video began to play.The three saw that Zhao Tianyong was still standing in the same direction as the previous two videos. Compared with the previous two videos, this time his state was obviously relaxed.Holding a glass of wine in his hand, he took the initiative to approach the crowd, and many people greeted him on the way. The computer showed that the time was almost one o'clock in the morning. There was a person in his arms, and the two walked out of the crowd. Stepping away from the dance floor, it happened to be one o'clock. "

"The person in Zhao Tianyong's arms is Gu Manman. When I saw her, she was wearing a black vest and white hot pants." Su Zhiqian said.

Gu Manman's back was turned to the camera. Sheng Nanfeng had previously said that someone had seen Zhao Tianyong take away the person. Counting this surveillance video, there were both witnesses and physical evidence.

"Forensic doctor Su, great!" After a compliment, An Ningshuang stretched her waist, glanced at the time on the wall, and said, "Boss, look that I have completed the task! Hey, it's one o'clock in the morning, you Aren't you going to reward me and Su Forensic Doctor?"

After finishing the work at hand, Su Zhiqian was really hungry.Thinking about it carefully, after returning from the airport, I was busy with things yesterday, and I was scrambling to solve all three meals.

"What do you want to eat?" Luo Shixian was accustomed to what An Ningshuang said, so he opened the takeout app on his phone and asked.

"Haha, I can eat anything!" An Ningshuang grinned, tilted her head, and asked the woman with short hair beside her, "Forensic doctor Susu, just order whatever you want, our old family has rich mines."

"I'm not picky about food." Su Zhiqian curled his lips and smiled, and his reply was neither humorous nor polite.

"That's it! Boss, I'm always the same. Just watch what forensic doctor Su eats! Hee hee..." An Ningshuang smirked, and threw the problem to Luo Shixian.

"Okay." Luo Shixian was not annoyed and lowered his head to order.

Su Zhiqian had no extra thoughts about the interaction between the two. He glanced at the content of the case analysis question board, and a thought popped up in his mind: "Captain Luo, there is one thing that confuses me."
