twin detective

Chapter 137

It was almost midnight when Ning Zhi came back after completing the notes.

The office is very quiet, with the unique tranquility at night.

Ning Yuan fell asleep at some point, lying on the desk, with a clean cup in his hand, it looked like it hadn't been touched, but Ning Zhi glanced at it, and immediately saw the extra cups in the trash can. That empty milk powder stick.

This thing is convenient and affordable, and it is a must for home travel, but for a grown man, it can't really be used as dinner.Ning Zhi wanted to wake him up and let him eat an apple, but after hesitating for a while, he decided to give up.

He seemed to have slept soundly, lying there like a well-behaved kitten.Even Ning Zhi put an extra coat on his back, but nothing happened.

Ning Yuan didn't sleep very well that night, he was drowsy, and even dreamed about the sets on the stage.For a while it was a majestic fairy palace, and for a while it was a big green tree.

The strangest thing is that Mr. Wang also appeared on stage as an actor.He turned into Titier's grandfather, no longer kind and peaceful, but cruel and violent. The child just said something very ordinary, and he took out a kitchen knife and chopped off his right palm...

God, what a nonsensical nightmare this is.

The moment Ning Yuan woke up, he was even a little grateful for the alarm clock at hand.When he looked up, he saw his brother standing in front of the whiteboard for an unknown how long, but the whiteboard was covered with dense handwriting.

What is written on it, Ning Yuan can guess even if he doesn't read it.He got up and had a simple breakfast, and then spent most of the day in the laboratory. When he saw his brother again, it was already the evening case analysis meeting.

Ning Zhi still stood on the left side of the curtain as usual, and simply linked the photos taken at the crime scene with the points already mentioned before.Ning Yuan followed one by one, and when he looked up again, he found that the photo had been changed, and it looked like a dusty footprint.But the location they are in is a place they haven't been to yesterday.

Looking at the structure here, it should be the side entrance of which teaching building, but the exact location is still to be discussed.Ning Yuan recalled subconsciously, but saw his brother raised his chin in the direction of Fang Ye, "You tell me."

"This is the side entrance of the new film and television building. When you come out from this side, you can directly see the promenade and sculptures on the opposite side, but the location here is relatively remote. After asking, I found that most people would not choose to go this way." Fang Ye responded. Standing up, he pointed to the photo again.

"It is precisely because of this that there is a lot of dust here, but there are few footprints. On the second step, I found a footprint, which can be determined to be 42 yards. The suspect is a male. Of course , this alone cannot be sure that it is left by the suspect, I suspect it because there is a drop of blood next to it."

"It's here." Ning Zhi cooperated with the laser pointer and spun around the blood drop, "From the appearance, this should be a blood drop. After laboratory testing, it can be confirmed that it is the blood of the deceased."

"There are a lot of people on campus. Even if he fled through the side door, the suspect should have cleaned up the blood on his body, and the victim was left at the scene without taking him away, so the drop of blood on the steps should have been taken away by him. It was left unintentionally when the palm was severed."

Fang Ye responded to this sentence in a timely manner, and motioned Ning Zhi to turn the PPT to the next page, "This is the black plastic bag in which the severed hand was placed. I have checked it carefully and found no loopholes or nail scratches. The scratches and the drop of blood should have been accidentally dropped by the suspect when he was packing the bag, otherwise, there might be a lot of blood dripping, and we can better judge the direction in which the suspect fled.”

"The gloves found at the scene have been confirmed. I found an auntie of the sanitation worker in the school, and she made it clear that these are the cleaning tools they often use." Zhi cut the PPT for everyone to see clearly, and soon turned to the next page. On it was a photo of a sanitation worker's overalls, which was the most common style of orange vest.

"The filament found on the button of the deceased can be confirmed to be made of nylon, which is consistent with the fabric of work clothes seen on the market, but to determine its origin, we need to wait until we find the clothes the suspect was wearing at the time. to make a comparison.”

The wound of the deceased was on the neck, extending to the main artery, and the murder weapon held by the murderer was only about the length of an ordinary ruler. At such a close distance, blood must have been splashed on his body, and it is very possible that the bloody clothes were burned afterward. of.

There are many green plants at the side door, and most of the lights are small chandeliers for outdoor decoration, and the lighting effect is not very great.

The light there was very dim, and the suspect was wearing overalls, wearing a mask, and carrying the most common black garbage bag in his hand. Standing on the steps, he would not attract attention at all.He then walked across the footpath, threw the bag into a nearby trash can and fled.

Moreover, it may be the same road they took last night.

After listening to the conclusion, Ning Yuan couldn't help but think of this scene. He looked up again and found that the possible roadmap had indeed been displayed on the PPT.Not only the floor plan found by the team, but also a few pictures that the school posted on the bulletin board for the guests for exchange activities.

"This is the rough road map. The suspect came out from the side door, bypassed the path downstairs, and arrived at the trash can. I personally infer that the murderer should be familiar with the terrain and have lived and worked nearby for a long time. But you have to judge him For the specific circumstances of the crime, let’s see the conclusion of the doctor.”

Ning Zhi pointed to the road map and came to a rough inference.

Outside the sidewalk is the driveway, and cameras are installed on the street lights. In comparison, the suspect is more likely to choose the sidewalk under cover.Ning Yuan made a comparison, and took the USB flash drive to his brother's place.Ning Zhi replaced the PPT without any hassle, and then returned to his seat.

It's been some time since they separated, but it's a tense crime scene and laboratory again when they don't know goodbye.Fang Yuan stared at the person, feeling a little inexplicable for a while, she felt that she seemed to be still trapped in the embarrassing atmosphere of being explicitly rejected by Ning Yuan, but she couldn't tell what it was exactly.

However, this is work, she can only force herself to focus on the PPT, not on Ning Yuan.

Ning Yuan didn't notice the gazes from the audience, but adjusted the PPT to the position he needed, and what appeared on the screen was a knife.The lights in other places in the conference room were dim, which made the knife more dazzling. Ning Yuan circled it with a laser pointer and began to describe the condition of the tool.

"This is an osteotomy knife commonly used for amputation or bone setting in orthopedic surgery. Its specification is a flat blade, about 23 centimeters long and about 8 centimeters wide. Judging from the cross-section of the injured palm of the victim, the murder weapon is this kind of knife. The possibility of a scalpel is relatively large. In addition, the wound on his neck was also caused by a flat-bladed tool, and it is initially judged that the suspect used only one knife."

"The reason why it can only be speculated based on the function is that there are not many tools on the market that can cut bones in a short time, and the cross-sections of the two wounds are very flat, but because of the special location, the murderer only used thorns and The method of cutting, rather than stabbing, so there is no way to determine the specific length of the murder weapon through the depth of the wound, and we can only identify it after finding the tools."

In the laboratory, Fang Yuan had also seen the specific shape of the two wounds. She subconsciously helped Ning Yuan explain, and found that the other party smiled at her.

The smile could be seen in the eyes, but Fang Yuan felt as uncomfortable as fine sand got in the eyes accidentally.

"Well, that's it. Junior sister is quite right." Ning Yuan summed it up briefly, and walked towards the audience, "The specific situation of the deceased will not be confirmed until after the autopsy. Team Ning has notified the school and family members There."

"Is this kind of scalpel the murder weapon?" Fang Ye pursed his lips while looking at the photo on the PPT, and covered his wrist, "I suddenly felt a pain in my bones."

"The specific specifications are still uncertain, but it should be this kind of scalpel."

scalpel.

After Ning Yuan's voice fell, there was no one to answer for a long time. The meeting room was quiet for a while, and finally Ning Zhi spoke up, "This case is quite similar to the last one. It's just that it looks like a case in the industry." Committing the crime, without other specific evidence, cannot be considered a serial case.”

These are only inferences from the objective situation of traces and tools.

However, there is still no way to give a specific explanation for the slap print on the deceased's face, the pinch mark on the neck, the severed palm and the ring on the little finger, and the eye-catching word "net".

However, these marks or redundant behaviors are the things that can truly reflect the suspect's motives for committing crimes.

Ning Zhi was still thinking about these things until he got home from the meeting. When Ning Yuan brought some snacks and went in, he found that there were a few more A4 papers on the desk, all of which were densely packed with black notes.There are also books on criminal psychology and semiotics next to the computer. You can tell what he is doing just by looking at it.

Being interrupted during his thinking can simply make even the best-mannered person fall into a state of rampage. Ning Yuan put the tray and went out to read. Who knew that at eleven o'clock he was ready to wash and go to bed, and when he went in to check the situation, he found him My brother is actually still in the study, and the computer screen is just the page of HowNet, obviously looking up documents.

"How many hours did brother sleep last night?"

After Ning Yuan and the others finished reading the paper, they raised their hands and waved in front of the computer.Touching the cup next to him, he found that the glass was already cold, and the small snack plate was basically untouched.

Did you stay up late last night?

How many hours did you sleep?

As long as this kind of question is asked, it is simply the prelude to be beaten.

Ning Zhi could feel that he was instantly filled with the desire to survive, and was so anxious to find a solution, that he hurriedly made up a lie and rushed to the bathroom.
