Solving the case: Combining the police dog's olfactory genes at the beginning

Chapter 320 The secret lies within a few inches

Located next to a green belt on the campus of Jiangzhou University of Science and Technology, there is a large trash can.

On weekdays, the storage buckets used by sanitation workers on the street are of the same type. Unfortunately, they are placed in the corner and are not very eye-catching.

This location is relatively remote, because it is close to the back of the teaching building and a certain distance from the main road, so the trash can is semi-abandoned.

There was no obstruction above the green belt, the lid was open, and a female corpse was lying inside.

The limbs were upside down, the head had been bent, and the spine at the neck had been broken, probably caused by the fall.

Luo Fei could see this detail at a glance.

In the field of profiling, every step I took here was within the clue range. Every detail of the body in the barrel was infinitely magnified, revealing the past of the case.

There were a large number of wounds on the woman's chest and abdomen, which should have been pierced by sharp objects.

The blood has long solidified, and there are still many flies flying around at this moment, which shows that it has been a long time.

The weather was not warm, but the stench still drifted through the thin air-conditioning into the respiratory tracts of the people around.

The other party's victim should have been a few days ago.

He never expected that such a thing would happen.

"Principal, director, I really don't know about this matter! I haven't been able to contact him in recent times. I have negotiated with this student's father, but there are no clues..."

"Sorry, Mr. Duan, I offended you."

It is also more consistent with the time given by Dan Duan Baoping when he reported the crime.

The plot was so bad that the principal and several directors looked gloomy and helpless.

At this time, the dean and even the principal rushed over. They were all shocked when they saw that the police had arrived. It was difficult for the teachers and students of the school to explain that such a thing happened suddenly.

Such an outstanding young girl passed away in such a miserable manner. It is truly an unacceptable tragedy.

The next moment, Duan Baoping roared like a ferocious beast and charged towards the surrounding crowd.

The school janitor and some security guards covered their noses and moved aside, but in order to maintain order, they could not flee the scene directly.

Recalling the scene just now, he almost collapsed.

The temperature here was too low, and coupled with the current weather, it took a few days for the stench of the corpse to come out.

The moment he saw the female corpse, Duan Baoping had already passed out.

This is the only way to calm him down.

Luo Fei and the others compared the girl in the contract based on Duan Baoping's previous introduction and the photos and personal information provided. They found that the girl was indeed the missing female student Duan Ying.

At the same time, he kept yelling and asking why they wanted to kill their children.

I haven't seen each other for a while, and I'm still curious where he went?

Luo Fei and the others also collected some information at the scene.

Not only does she have a cheerful and lively personality, but she is also kind to others and has excellent communication skills. It can be said that she is a girl that everyone loves.

On weekdays, Duan Ying's classmates, some of his roommates, and friends all come here.

"Comrade police, what is going on?"

At this time, the comatose father woke up.

After all, something happened on campus, and he, the counselor, must be held accountable.

If the other party continues to make trouble like this, this place may really become a mess.

Facing the principal's inquiries, a fat man hurriedly stepped forward. The other person was Duan Ying's counselor.

The two parties negotiated for a long time, and then they realized that they and Duan Ying were out of touch.

But today, she was suddenly found in the trash can by the school janitor, and she was found in such a tragic death state...

It was obvious that he had completely lost his self-control due to a brief period of madness. Luo Fei stepped forward to stop and comfort him, but he was able to break away...

Because Duan Ying plays a very important role in their circle.

In other words, no one knew where this girl had gone in the past few days.

It looked like the other person had been dead for a while, and the blood stains on his body had long dried, and there were even some signs of freezing.

After seeing their sisters become like this, without exception, they all turned pale, looked frightened, and some even started vomiting...

So Luo Fei acted as the cruel person and slapped the opponent on the back of the neck with his bare hands, knocking him out.

But everyone acted very sad afterwards, without any exaggeration.

"This...what is going on?"

No one here wanted to start a fight with the poor father.

He ran to the trash can and stretched out his hand to touch his daughter, but was stung by the shocking look and his eyes turned red for a moment.

"Xiaoying, my daughter, my child!"

In such a situation, he must be the one to blame.

But he felt extremely aggrieved, and he really didn't know what the reason was.

Others have already guessed the relationship.

The dean and counselors all came together. Now they, the higher-ups on campus, need an explanation for this matter. Otherwise, there is no way to explain it to other teachers and students.

If such a big case occurs, it will soon be posted on the Internet, and the situation will ferment much faster.

"Now it can be basically determined that the cause of death was first being stabbed with a sharp weapon and then being thrown downstairs, or falling from a height and breaking the spine. Both of these may lead to the final death. The specific cause of death has to wait for the forensic doctor to find out more. diagnosis results."

"Now we need to go up there to survey the scene. Teachers, please arrange for other onlookers to evacuate. Otherwise, it will affect our case handling process."

"Okay, okay, no problem..."

The dean and others immediately began to evacuate the surrounding students, but this behavior was completely unnecessary.

On university campuses, such terrorist incidents spread quickly like wildfire in the spring breeze, and the discussion and fermentation of the matter on the streets only contributed to the flames.

At this moment, Luo Fei and the others were not in the mood to care about this, but walked directly upstairs.

Everyone, including Zhang Wei, could see that in order to cause such a death, they had to be thrown from the teaching building, which was probably the first scene of the crime.

At present, Duan Ying's body and her father Duan Baoping have been temporarily sent back, and other on-site evidence collection work has come to an end for the time being...

The first group of people walked up the corridor with people coming and going and arrived outside a classroom.

This is the equipment room that stores some arts and crafts required by the grade group. Judging from the location, this is the best place to throw the body.

Luo Fei has already calculated it below using his talents in the profiling field.

The scene of the first crime must be among them!

When they pushed the door open and entered, they were stunned on the spot.

The scene was actually the scene where the murder occurred, with bloodstains everywhere and overturned tables and chairs, but what was surprising was that there were no traces of cleaning...

It's like the crime happened here, but the guy who committed the murder turned around and left without even bothering to clean up the mess.

What kind of crazy murderer is he? "This is too crazy. They didn't even clean up the scene. It's simply unreasonable."

"It's very possible that he did this on purpose, but there are some reasons that don't make sense. Wouldn't such an arrangement leave clues?"

"Clues will definitely be left behind!"

Luo Fei answered decisively.

"I think there are two reasons why the other party didn't clean this place up."

"The first is that the other party intends to kill people here, and is not afraid of it. Only by doing this can he convince himself not to care, because he is mentally prepared for concealing the truth in the future or for the incident to be exposed. The psychological strength of such a guy is It’s amazing.”

"The second is that the conditions do not allow it. The blood stained situation here is very messy. The murderer must have considered the environment when he committed the crime. It is best to leave as soon as possible after killing and dumping the body. If you stay here and get stained with blood, you will be killed by students once you go out. They noticed.”

Luo Fei's analysis made sense, and Zhang Wei and others nodded.

When they came up just now, they found that there were quite a lot of students coming and going on this floor.

Although no one has entered this equipment room, there is a risk of being noticed if there is any flaw in the equipment room.

"It seems that the murderer has been confirmed to be someone from this school, otherwise he wouldn't have been able to handle it so easily."

"Why don't we check the last person who entered here? If this is a murder scene, there will definitely be clues."

"I just thought of this, but the monitoring distance on this level is limited."

Luo Fei pointed to the distance.

"The surveillance on this floor is on the other side of the corridor. There is no coverage here, so it happens to be a blind spot."

"I think the perpetrator must have thought of this too."

Zhang Wei and the others sighed after hearing this.

"Ugh."

"The next step is to find a needle in a haystack. There are so many people in this school. If we investigate them one by one, even if we go through all the suspects, it will probably take a lot of time."

Lin Jie also added on the side.

"Yes, we don't know much about this girl named Duan Ying yet, so we can't analyze the identity of the murderer."

While the three of them were discussing the matter, Luo Fei had already returned to the equipment room.

There are many reasons why no one visits this place.

Maybe it's because I haven't used it in courses recently.

Or maybe only teachers come here occasionally to pick up things on weekdays, so it is normal for this area to be idle for a long time.

And the person who knows the conditions here must also be a member of the school.

This range is already very small!

The reason why Zhang Wei and the others found it troublesome was that they had no clue.

But I am different!

With the profiling field and the narrow thinking space, it is not difficult to decipher the clues in this classroom full of doubts and flaws.

So Luo Fei started walking around the wall in the room, observing the area in the middle from all directions.

There were mottled blood stains on the ground, and some even spattered on the table, but the swaying handicrafts were not broken, indicating that the fighting and killing process between the two parties was not intense.

This makes the case interesting.

If the murderer and Duan Ying had a secret meeting here or there were other reasons, then it can be explained.

But if that were the case, how could it turn into murder? Could it be that it was planned in advance?

"Team leader, what are you looking at?"

At this critical moment, Zhang Wei and the others came over and interrupted Luo Fei's thoughts. This was a bit embarrassing.

He could analyze the actions and details of both parties here at a glance, but a sudden sentence pulled him back from his thoughts.

"It's nothing, I'm just thinking about the process of their crime. It's still too early to investigate the perpetrators. There are many suspects. If you rush to investigate, you may alert the snake. Let's use the elimination method to find out some details first, and try to find them right away. .”

Luo Fei said seriously.

He Xin suddenly pointed to the footprints under the table, which were several messy footprints.

"Team leader, look, there are bloody footprints here!"

Luo Fei was a little surprised when he heard that. He didn't expect that there were also footprints under the pillar. How did he get the footprints there?

Could it be that the victim and suspect rolled underneath?

Several people followed He Xin's gaze downwards and saw a few messy footprints in an area where the blood was solidified. It was still relatively clear now.

It can be seen from the lines on it that these are the shoe prints of two people.

However, the sizes are relatively small, not like men's shoe sizes, but more in line with women's foot shapes and styles...

Two girls?

Luo Fei put his hand on his chin, thinking about the suspect. Could it be that the murderer is also a woman? No, it's not that simple.

This is very likely to be a cover-up, so no conclusion can be made hastily.

"The friction on one of them is quite serious. It looks like it was after a struggle, so there is a high chance that it belongs to the victim."

"another……"

Zhang Wei lay on the ground and shined a flashlight inside.

"The steps were very hard and not messy. If we go by the on-site reconstruction, this should be the murderer's footprints. But why does the blood stain under this footprint feel a bit weird?"

"It seems that someone has deliberately smeared it...the blood was not splashed, and the stain marks were smooth, which is contrary to common sense."

Luo Fei knelt down and looked there carefully.

"Huh, interesting trick, but unfortunately it's still too immature."

Several people on the side did not understand what the team leader meant.

Luo Fei raised his hand and pointed at the area that looked like it had been smeared, and his tone became serious.

"If there are two people here, one is the murderer and the other is the victim, then there should be only two types of footprints."

"But if one of the footprints was carefully modified, or the blood stains flowing on the ground were smeared and then stepped on again, then it proves that there is a third party here for the purpose of concealing the truth."

"This murderer also has an accomplice. To be precise, he is not necessarily an accomplice, but more like a scapegoat who willingly was suspected."

"A man who is truly willing to sacrifice his life to stop the truth!"

Speaking of this, Luo Fei took a breath of cold air. This situation was indeed a bit speechless. There were obstacles everywhere for them and the police.

"The secret lies within a few inches!"

"As long as we find the person who deliberately rectified the scene, then everything will be revealed."

As soon as these words came out, the three people next to them looked bitter.

It is already difficult to find the murderer, but it seems to be even more difficult when such variables appear.
