Chapter 173.

Cheng Mo got someone to make a dummy that was about the same height as Nojiri, then bought a piece of pork with skin and tied it at a comparable height to the neck.

Then he sent someone to find some sharp knives that could be bought on the market.

According to Dr. He’s many years of experience in examining injuries, the blade that cut Nojiri’s carotid artery should not be a long blade, and its length should not exceed thirty centimeters at most.

Without finding the murder weapon at the scene, we can only conduct experiments to compare the wound to see which blade best matches the wound.

And the wound was formed by a knife, indicating that the person who used the knife must be an extremely experienced, at least certainly not the first time.

And of course that includes a sharp scalpel.

A dagger, a scalpel, a sharp knife for boning, a razor for shaving, and even a bayonet for a standard rifle.

Judging from Nojiri’s facial expression and muscular reaction at the time of his death, he should have been caught off guard and had his carotid artery, as well as his throat, slit by someone wielding a knife.

So it must have been a close-range swing, and the blade must not have been long; if it had been a long blade, it would not have been able to be hidden, and would have been discovered long ago.

Nojiri neck this knife from left to right, diagonally downward cut down, from the depth of the cut and muscle reaction can be seen, the force is also a big to small process, a very sharp knife.

This murderer should be about the same height as Nojiri, because of the summer, the neck is exposed to the air, it is easier to get down.

After testing several handfuls of them one after another, none of them were able to achieve the effect of the cut on Nojiri’s neck, and the closest was actually the scalpel provided by Dr. He.

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

But comparing the wounds formed by the two, there were still differences, mainly because the opening formed at the beginning of the scalpel’s downward stroke was not quite the same shape as the wound in Nojiri’s neck.

It was most likely the murderer’s homemade knife, not a conventional one, so it was impossible to make an accurate judgment.

It looks like the murder weapon will have to be found.

As for whether or not that severed alley was the first crime scene, Cheng Mo still needed to go and survey it once more, and this time, he called Forensic Doctor He on board.

Yesterday he went there, some questions could not be seen, today bring the forensic doctor, or blood will be able to have the answer.

Cheng Mo and the others drove to the crime scene.

Because of the murder in the alley, the police station that pulled a cordon, but also arranged for people to guard, the scene was not further destroyed.

A puddle of blood on the ground had already dried.

That was the location where Nojiri had fallen after his death, and Cheng Mo asked Lu Le to bring over a photo to compare it to the imprints spilled by the white ash on the ground.

“Medical Examiner He, can you tell from the amount of bleeding on the ground that this is the first crime scene?” Cheng Mo asked, pointing at the blood marks on the ground.

Medical Examiner He squatted down to come, “Cheng Tan, according to my experience, this amount of bleeding should be more than eight hundred milliliters, a normal person’s whole body blood is about between four and five liters, one fifth of the blood loss will lead to shock, and one fourth without blood transfusion will lead to death. ”

“So, you judged this to be the first crime scene?” Cheng Mo nodded.

Coroner He nodded, “It should be.”

“The murderer killed someone and left gracefully, he also took the murder weapon with him, do you think that there was any blood of the deceased splattered on his body?”

“At close range, the carotid artery would have formed a jet, judging from the spotty distribution of blood scattered at the scene then ……,” Forensic pathologist He noticed that there were no continuous traces of spattered spotty blood seen on the ground at a certain spot where Nojiri’s body had fallen.

Cheng Mo also noticed it.

It was obvious that the murderer must have spattered blood on his body. If a person was walking on the street in broad daylight, wearing clothes with blood on them, they would definitely be noticed, but if it was nighttime and they were wearing a dark-colored dress, then they would not be easily seen.

But the time point of Nojiri’s death was between 8:00 and 10:00 p.m. If Xia Ran hadn’t lied, then it should only 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 would have been around 8:00 o’clock.

The time was right, but who would have known that he went to Charan’s place that night and prepared in advance to intercept him on the way? Was Inoue Nikiaki deliberately killing and planting evidence, a thief catching a thief, and anyway, Nojiri was already exposed to him, so it was a good idea to take advantage of it and put pressure on the Bureau of Public Works?

Or is it something else?

Nojiri’s wife Keiko is also suspected, from the couple had been quarreling before, Keiko also knew her husband’s relationship with Xia Ran, and even designed to drive away Xia Ran, the results of Nojiri and Xia Ran instead of breaking off the relationship, Keiko as a wife, she is a motive for murder.

But she only drove Xia Ran away before, but she didn’t have any excessive behavior towards her husband, could it be that she couldn’t stand it anymore this time? Keiko mentioned that Nojiri was going to buy her pastries from Apricot Flower House, but Xia Ran never saw them, did Nojiri not go to buy them, or did this Xia Ran lie?

No matter who it is, there is always a person who lied, but whether Nojiri went to Apricot Blossom House to buy pastries or not, directly go to Apricot Blossom House to inquire about it, it’s not that difficult to know.

Three o’clock in the afternoon.

Case summary and meetup.

“I’ll start, the victim of this case Nojiri Taro, thirty-one years old, Tong Yuan foreign bank customer specialist, into the Tong Yuan foreign bank less than a year, before it is said to be working in Qingdao, the specific what to do, not clear, his work is mainly to maintain and open up new customers, the Tong Yuan foreign bank is to do foreign trade, the main business is the cotton yarn and non-ferrous metals, Nojiri Taro was killed before, according to his colleagues in the foreign bank introduction He generally does not sit in the foreign bank, just come over every day to report, and then went out to run the business, specifically where to go, this only he knows, anyway, he did business is still very good, performance in the foreign bank of the commissioner is not the best, not bad, is considered the middle level, the day of the incident, it is very strange, he did the day shift in the foreign bank, did not go anywhere, less than half past five, he left early from work! ……”

“Old Lin?” Cheng Mo interjected.

“I know what Inspector Cheng wants to ask, indeed before he left work, a phone call came into the foreign bank, it was for Nojiri, claiming to be her wife, after Nojiri answered the phone call, it didn’t take long before he left work and went home, he didn’t even take his own briefcase ……” Lin Huarong continued to describe the the information he had gotten from his own investigation.

“I also went to the Apricot Flower House and asked, and I haven’t seen Taro Nojiri among the people who went to the Apricot Flower House to buy pastries at that point in time that afternoon.”

“Chief, if it’s not that Nojiri Taro didn’t buy the pastries, then his wife Keiko is lying.” Lu Le reacted quickly and immediately thought of the crux of the matter.

“What if Nojiri just forgot, or didn’t want to buy them, and since the person died anyway, there’s no evidence that Keiko lied?” Cheng Mo affirmed Lv Le’s analysis, but it was only one scenario, not unexplainable.

Lu Le was speechless over it.

“Old Lin, did Nojiri bring back his briefcase?”

“Brought it back, but there’s nothing of value inside.” Lin Huarong nodded, he was also an old inspector, the victim’s belongings, this was an important clue, naturally, he had to get it back.

“This briefcase of his hasn’t been touched, right?”

“What Detective Cheng means is to have the fingerprint trace inspection team check it?” Lin Huarong froze for a moment, not understanding why Cheng Mo thought so.

“It’s not a bad thing to check, you didn’t leave anything on it, did you?”

“No, such an important object, how could I dispose of it at will.” Lin Huarong busily said.

“Old Xu, what did you find out when you investigated Nojiri Taro’s social connections?” Cheng Mo turned his head to Xu Qinghe and inquired.

“I visited a few of his clients, and they all said that he is low-key and humble, and apart from being a bit of a womanizer, he doesn’t have any major problems, and I haven’t heard that he has offended anyone.” Xu Qinghe replied.

“Detective Cheng, if it’s not a vendetta, and it’s not going for property, or an acquaintance committing the crime, then it’s a love killing.” Lin Huarong said.

“No matter what the motive of the murder is, the most important point for us at the moment, that is the search for the murder weapon, I went to the funeral parlor today, and did a morning test with the medical examiner He, and went to the scene, I was not able to determine what kind of murder weapon the murderer used to kill the person, but what can be determined is that that severed head of the alley is the first scene of the crime, the murderer left calmly after the murder , and has not been discovered, he should have planned everything long ago and made preparations, this is a premeditated murder!”

Cheng Mo set the tone.

This was a murder case, the nature was set.
