The Bourne Counterattack

Chapter 173 What is the murder weapon?

Cheng Mo found someone to make a dummy that was about the same height as Nojiri. He also bought a piece of pork with skin and tied it at the same height as the neck.

Then send someone to find some sharp knives available on the market.

According to Forensic Doctor He's many years of experience in examining injuries, the blade that cut Nojiri's cervical artery should not have been a long blade, and the length should not exceed 30 centimeters at most.

When no murder weapon was found at the scene, experiments could only be conducted to see which blade most closely matched the wound.

Moreover, the wound was caused by a single knife, indicating that the person who used the knife must be extremely experienced, at least it was definitely not the first time.

Of course, a sharp scalpel is also included.

Daggers, scalpels, boning knives, razors for shaving heads, and even standard rifle bayonets were brought.

Judging from Nojiri's facial expressions and muscle reactions when he died, he should have been caught off guard, and someone slashed his neck arteries and throat with a knife.

Therefore, this must be a close-range sword swing, and the blade must not be long. If it was a long blade, it would have been discovered long ago if it could not be hidden.

Cheng Mo and others drove to the crime scene.

That was the spot where Nojiri fell to the ground after his death. Cheng Mo asked Lu Le to take the photo and compare it with the marks of white ash on the ground.

It looks like the murder weapon needs to be found.

However, when comparing the wounds formed between the two, there are still differences. The main reason is that when the scalpel was first used, the shape of the opening formed was different from the shape of the wound on Nojiri's neck.

This is probably a homemade knife made by the murderer, not a regular knife, so it is impossible to make an accurate judgment.

Forensic Doctor He nodded: "Probably."

"Forensic Doctor He, can you tell from the amount of bleeding on the ground that this is the scene of the first crime?" Cheng Mo asked, pointing to the blood mark on the ground.

As for whether the dead end alley was the scene of the first crime, Cheng Mo needed to investigate again. This time, he also called forensic doctor He.

"So, do you think this is the scene of the first crime?" Cheng Mo nodded.

The pool of blood on the ground had dried.

"The murderer killed someone and left calmly, taking away the murder weapon. Do you think there was any blood splattered on him?"

Forensic Doctor He squatted down and came over: "Tan Cheng, according to my experience, the amount of bleeding should be more than 800 milliliters. A normal person's whole body blood is between four and five liters, and one-fifth of the blood loss is , they will go into shock, and a quarter of them will die if they don’t receive blood transfusion.”

The knife on Nojiri's neck was cut diagonally downward from left to right. It can be seen from the depth of the knife edge and the muscle reaction. The force is also a process from large to small, and the knife is very clean.

I tried several in succession, but none could achieve the effect of the knife on Nojiri's neck. The closest thing was the scalpel provided by Dr. He.

He went there yesterday, but there were some questions that he couldn't tell. Today, if he brought a forensic doctor or blood, he would be able to get the answer.

Because a murder had occurred in the alley, the policeman in the patrol room had put up a cordon and arranged for people to guard the scene, so that the scene was not further damaged.

Because the scalpel is sharp enough, the incision is also the deepest.

The murderer should be about the same height as Nojiri. Because of the summer, his neck is exposed to the air, making it easier to kill.

"At close range, the carotid artery will form a jet. Judging from the spot distribution of blood scattered at the scene..." Forensic doctor He noticed that there was no continuous sputtering on the ground where Nojiri's body fell to the ground. Dotted traces of blood.

Cheng Mo also noticed.

It was obvious that the murderer must have been splattered with blood. If a person walks on the street wearing bloody clothes in broad daylight, he will definitely be noticed, but if it is late at night and he wears dark clothes, it will not be easy to be seen.

But the time of Nojiri's death was between 8 o'clock and 10 o'clock in the evening. If Xia Ran didn't lie, then it should have been about a quarter of an hour for him to walk from Xia Ran's house to this location, so the time of Nojiri's death was around eight o'clock. look.

The time was right, but who would have known that he went to Xia Ran's place that night and was prepared to intercept and kill him on the road?

Was it Inoue Hizaki who deliberately killed people and framed them, and the thief caught the thief? Anyway, Nojiri was already exposed to him, so he could use it to put pressure on the Ministry of Industry and Commerce Bureau?

Or is there something else?

Nojiri's wife Keiko was also suspected. The couple had been quarreling before. Keiko also knew about her husband's relationship with Xia Ran, and even designed to drive away Xia Ran. As a result, Nojiri and Xia Ran not only did not break off the relationship, Keiko, as his wife , she had the motive to kill.

But she just drove Xia Ran away before, but did not do anything drastic towards her husband. Could it be that this time she couldn't bear it anymore?

Keiko mentioned that Nojiri wanted to buy her pastries from Xinghualou, but Xia Ran didn't see it at all. Did Nojiri not buy it, or did Xia Ran lie?

No matter who it is, there is always someone who has lied. But if Nojiri went to Xinghualou to buy cakes, he can just go to Xinghualou and find out. This is not a difficult matter.

3pm.

Case summary and meeting.

"Let me start by saying that the victim in this case, Taro Nojiri, is 31 years old. He is an account specialist at Tongyuan & Co., Ltd. He has been with Tongyuan & Co. for less than a year. He was previously said to be working in Qingdao. It is unclear what he does specifically. His job Mainly to maintain and develop new customers. Tongyuan Foreign Trade Co., Ltd. is engaged in foreign trade, and its main business is cotton yarn and non-ferrous metals. Before Taro Nojiri was killed, according to his colleagues at the foreign trade company, he usually did not work at the foreign trade company, but only came to report every day, and then he went to work. He went out to run a business. Only he knew where he was going. Anyway, his business performance was very good. His performance was not the best among the specialists of foreign companies, nor was it bad. He was considered to be in the middle of the pack. On the day of the accident, he was very It's strange, he worked a day shift at a foreign trade company and didn't go anywhere. Before half past five, he got off work early and left..."

"Old Lin?" Cheng Mo interrupted.

"I know what Cheng Tan wants to ask. It is true that before getting off work, a call came into the foreign bank. It was for Nojiri, claiming to be her wife. After Nojiri answered the call, he went home from get off work not long after, even himself I didn’t even take my briefcase..." Lin Huarong continued to describe the information he obtained from his investigation.

"I also went to Xinghualou to ask. At that time that afternoon, no one who went to Xinghualou to buy pastries saw Nojiri Taro."

"Boss, if Taro Nojiri didn't buy pastries, then his wife Keiko lied." Lu Le reacted quickly and immediately thought of the key to the problem.

"What if Nojiri just forgot or didn't want to buy it? Anyway, the person is dead and there is no evidence to prove that Keiko lied?" Cheng Mo confirmed Lu Le's analysis, but this was just a situation and not unexplainable.

Lu Le was speechless.

"Old Lin, have you brought Nojiri's briefcase back?"

"I brought it back, but there was nothing valuable in it." Lin Huarong nodded. He was also an experienced police officer. The victim's belongings were important clues, so he had to get them back.

"His briefcase has not been touched, has it?"

"What Detective Cheng means is that we need the fingerprint inspection team to check?" Lin Huarong was stunned for a moment, wondering why Cheng Mo would think so.

"It wouldn't be a bad thing to check it out. You didn't leave anything on it, right?"

"No, how can I dispose of such an important item at will?" Lin Huarong said hurriedly.

"Old Xu, what did you find when you investigated Taro Nojiri's social connections?" Cheng Mo turned to Xu Qinghe and asked.

"I visited several of his clients, and they all said that he is low-key and humble. Apart from being a little lecherous, he has no major problems. I have never heard that he has offended anyone." Xu Qinghe replied.

"Detective Cheng, if it wasn't a vendetta and it wasn't for property, but an acquaintance committed the crime, then it was a love killing." Lin Huarong said.

"No matter what the motive for the murder is, the most important thing for us at the moment is to find the murder weapon. I went to the funeral home today, did a morning test with Dr. He, and went to the scene again, but we couldn't identify the murderer. What kind of weapon was used to kill the person? But what is certain is that the alley with the severed head was the first scene of the crime. The murderer left calmly after the murder and was not discovered yet. He should have planned everything long ago. , be prepared, this is a premeditated murder!"

Cheng Mo set the tone.

This is a murder case, its nature has been determined.
