What they saw in front of them surprised everyone.

Previously, everyone just wanted to talk to He Ling about the Watchmen.

I didn't expect it.

No one thought of it.

came to He Ling's house to look for her, and encountered this situation.

He Ling's sister He Qi was dizzy and fainted on the ground again.

"Ms. Ho. Lu Weiwei took a look, quickly ran back to help her up, and pinched He Qi's middle with her fingers, which made He Qi wake up from her dizziness.

"Police...... Comrade policeman, my sister she ...... How could she be like this?"

"She was fine before, I told her to go to bed early last night, why is it like this today?"

Seeing that He Qi couldn't cry, Gu Chen didn't care about her, but habitually took out the white gloves from the equipment bag.

After admitting the law enforcement memory, he handed it to Yuan Shasha on the side and said, "Xiao Yuan, you help me take it well, and take pictures of every angle." ”

"No problem. Yuan Shasha, who was familiar with Gu Chen's work, immediately took over the law enforcement recorder and began to shoot accurately as far as Gu Chen's eyes could see.

Judging from He Ling, who was hanging at the top of the stairs, she had two ropes wrapped around her neck.

One is an orange power extension cord and the other is a black cord.

Her hands were tied behind her back with white ropes, and her feet were also tied with white ropes.

The whole human body was just suspended from the railing of the staircase.

However, what is shameful is that He Ling's upper body is wearing a dress, similar to a hip-hop T-shirt, loose and fat, and the length can cover the base of He Ling's legs.

is to wear a pair of skinny denim shorts in the summer, and basically you can't see that He Ling is wearing pants.

But what makes people feel ashamed is that He Ling's waist down is full of fruit.

Gu Chen didn't care about these, no matter how good-looking his body was, in front of Gu Chen, it was just a cold corpse, a corpse to be studied for progress.

The cause of death is obvious, it was a single sharp blade assassination, and He Ling died of internal bleeding.

"This is a typical reasoning case. Officer Wang looked at He Ling's corpse in front of him and couldn't help but sigh with emotion: "This is too terrifying, isn't it? What is the murderer going to do? Demonstrate to us?"

The picture of He Ling being hung at the top of the stairs really shocked everyone present, just like He Qi who fainted, everyone was greatly shocked.

She ...... She hasn't gotten married yet, and she has just fallen out of love, why is this like this?" He Qi came to Gu Chen's side crying, and cried with grief:

"She's still so young, and she's still a lot of youth, but now she's dead at home, and she's hanging on the stairs, who is so ruthless?"

"Oh my God, what the hell is going on!"

"Ms. He, you calm down first, don't get excited, okay?" Seeing He Qi's emotional collapse, Gu Chen motioned to Lu Weiwei beside him and quickly pulled her aside.

Of course, Lu Weiwei was not idle, she clasped He Qi from behind with both hands, and pulled He Qi down the stairs like a subdued criminal.

"What is this all doing. Officer Wang tugged at his collar, and he was also angry:

"The previous threat letter, the Watchman, was already bad enough, but now that I finally have a new clue, I thought that the quiet would be about to break through, and I came to this again?"

Officer Wang is very angry now.

To be precise, he would never have imagined that he would discover so many strange things in a row.

If he had known that this kind of thing would happen, Officer Wang would not have agreed to come to He Ling again this morning.

Of course, many things are only regretted and then remembered how to do them.

If all of this is predestined, then even if you miss the time, it will happen again at some point in the future.

Officer Wang was panicked, the most important thing was that He Feng and he were old classmates and good friends, but now He Feng's affairs made him at a loss, and He Ling's sudden death also made him unexpected.

Therefore, Officer Wang felt that everything had not been going well recently, so he could only look at Gu Chen with an indifferent expression on the side.

Only Gu Chen can maintain his original intention and remain calm enough in this terrible environment.

"Gu Chen, what do you think?" Officer Wang said breathlessly.

"Looks like we're going to have to get a long report ready again. Gu Chen also shook his head, and said a little nothing: "At present, He Ling died of excessive blood loss. ”

"But judging from the fact that she was tied up, she should have been coerced, but the tools of this binding are somewhat amateurish, like some items in the house. ”

"You mean...... The rope that binds He Ling comes from the family?" asked Yuan Shasha.

Gu Chen nodded, and then asked He Qi, who was crying at the staircase, "Ms. He, if you want to investigate and deal with it as soon as possible, who killed your sister, please stop crying and cooperate with our investigation, okay?"

Gu Chen's words seemed to wake up the crying He Qi.

She was stunned, quickly wiped the tears from the corners of her eyes, and then said: "As long as you can find the brute who killed my sister, you can tell me how to assist in the investigation, I will listen to you." ”

"You come to me now. Gu Chen beckoned and motioned for He Qi to hurry over.

He Qi didn't hesitate, and came to Gu Chen's side in three or two steps.

"Where did this rope come from?, are you familiar?" Gu Chen asked.

"This ......" He Qi tried to calm down, and then leaned his head closer.

After a while, He Qi suddenly realized: "I know, the rope used to tie my sister's hands and feet is on the blinds in the room." ”

"Is it in the room?" Gu Chen asked again.

He Qi nodded, pointed to the staircase and said, "Just above, the first room at the staircase." ”

"Wait here, I'll take a look. Gu Chen's voice fell, and he ran to the top of the duplex in three or two.

Pushing open the door of the first room, I saw that the curtains had been pulled up and the ropes had been torn off.

"Is it on the curtains?" asked Officer Wang.

Gu Chen nodded silently: "That's right, the rope does come from the curtain." ”

Glancing at Yuan Shasha, Gu Chen said again: "Xiao Yuan, you go downstairs and bring our toolbox." ”

"No problem. After receiving the order, Yuan Shasha ran down the stairs as soon as possible, went to the trunk of the police car downstairs, and retrieved the toolbox that Gu Chen wanted.

At the same time, everyone began to put on gloves and foot covers, and then put on head coverings, striving not to leave a single hair of their hair on the scene.

After helping He Qi put on the trap protective equipment, Gu Chen also waited for Yuan Shasha's toolbox.

After a brief hesitation in unpacking, Gu Chen went out with a can of special powder spray.

The average person pulls the blinds and does not leave fingerprints on the ropes.

But if you tie it with ropes, you can't do it.

After Gu Chen untied the rope on He Ling's body, he slowly placed her body at the corner of the corridor, and then took out a special powder spray and sprayed it on the rope.

These equipment were all treasures from forensic assistant Gao Chuanfeng, and Gu Chen rarely used them.

But in order to save on-site inspection time and procedures, Gu Chen sometimes had to prepare some in the trunk of the vehicle.

Unlike other police officers, Gu Chen's team had to carry several special toolboxes in addition to wearing necessary police equipment.

In order to bypass the technical department, do it yourself, and collect evidence from some operational experiments on site, so that the detection effect can be quickly achieved.

Subsequently, the test results can be sent to the technical department of the municipal bureau, which greatly saves the workload of the forensic team of the technical department of the municipal bureau.

This is also why, Gao Chuanfeng always likes to give preference to the samples of Gu Chen's team for careful testing.

The reason is very simple, from the very beginning, Gu Chen has already completed the preliminary work required by forensic medicine by himself.

The technical department of the municipal bureau only needs to test and collect evidence for specific projects in accordance with Gu Chen's special requirements.

It can be said that Gu Chen helped forensic assistant Gao Chuanfeng remove a large number of necessary tests, and also chose to focus on the operation.

Such efficiency greatly helps both parties save time.

That's it at the moment.

Gu Chen used the special powder spray given by Gao Chuan Feng to spray the rope, hoping to display fingerprints on the special area.

But unfortunately, Gu Chen didn't find any fingerprints on the rope.

Gu Chen, who was not discouraged, then came to the curtain and sprayed all corners, but to Gu Chen's surprise, there were no fingerprints found in several key areas where the ropes on the curtain shutters were removed.

Seeing that Gu Chen's operation had made no progress, Officer Wang was also a little anxious: "This murderer is obviously prepared, he will not leave fingerprints at the scene, which is a bit troublesome." ”

Gu Chen frowned slightly, and said, "The entire residence has traces of being turned over, and the drawers have been opened, it looks like this is a burglary scene." ”

Looking back at He Ling's body, Gu Chen said again: "This shows that the purpose of the murderer entering this residence is very likely to be theft." ”

But in the process of his theft, He Ling happened to return home late at night and found the thief. ”

Although the thief had never killed anyone before, this time, he decided to kill someone. ”

According to the situation at the scene, Gu Chen made his own preliminary inferences.

"It could be so. Lu Weiwei walked to Gu Chen's side and agreed: "We have also seen a lot of burglary scenes, true and false, false and true, but today's crime scene definitely does not look like a deliberate mess." ”

"Judging from the mess of various items, it is very real, although these details cannot be seen by ordinary people, but we have seen it many times, and it will not be unclear. ”

"Of course I knew it was burglary. Officer Wang clasped his hands to his chest and frowned slightly: "But since this murderer is stealing, why did he choose to kill He Ling after meeting her?"

"But even if he killed He Ling, why did he hang her on the guardrail of the stairs, this is too arrogant, right? ”

Gu Chen said indifferently: "If you can't explain something, you can put it aside for a while, and choose a place that can be explained." ”

Gu Chen would never be entangled in this kind of thing.

Just like in exams, questions that you won't do can be put aside first.

It's impossible to spend a lot of time studying this question and give up on other topics because you can't do it.

If you do, it will be tragic to wait until the end of the exam.

The reason why Gu Chen's case-handling efficiency is extremely high is that he adopts the method of examination.

And the case is often a whole and needs to be broken through with multiple points.

Even if you hit a nail on the nail in this question, you can try something else.

When all the clues have made a breakthrough, going back and solving the difficulties can have a counter-evidence effect.

Gu Chen began to look for fingerprints throughout the residence......

In the end, Gu Chen found that there were still some fingerprints that could be extracted.

However, considering that some of the extracted fingerprints and palm prints are relatively blurry, they do not look like new fingerprints.

Maybe it's just a family member, or another friend, who stayed behind when they legally entered the home.

Gu Chen was still a little hesitant, and was ready to collect it first, send it to the Technical Department of the Municipal Bureau for archiving, and then consider extracting the fingerprints of other family members for archiving.

This is also the difficulty and pain point of fingerprint extraction.

However, after a series of searches, Gu Chen still found two hairs of unknown origin.

One of them was found at the top of the stairs, while the other was found on He Ling's body.

However, since neither hair has a root, a full DNA profiling test was performed on them.

There was a tissue under the stairs where He Ling's body was hung.

Gu Chen thought at first, maybe He Ling stayed behind when he was violated.

So Lu Weiwei was called and asked Lu Weiwei to help examine and dispose of He Ling's body.

And he examined the paper towels he found, hoping to find some biological evidence from them.

But the test result was negative, and Gu Chen did not find any suspicious points on the tissue.

At the same time, Lu Weiwei also did a preliminary examination of He Ling's body.

Especially on He Ling's body, no other biological fluids were found.

Therefore, the conclusion provided by Lu Weiwei to Gu Chen was that He Ling was most likely attacked by Xing, but the murderer did not leave any biological evidence that could be collected by the police.

"Since it was not violated, the paper towel was of little use. After Gu Chen folded the tissue, he still put it in the evidence bag.

That is to say, He Ling is likely to have found out that the murderer was stealing after returning home, and was attacked by the murderer. Officer Wang began to hypothesize the possibilities and said:

But later, after subduing He Ling, the murderer found that He Ling had some posture and tried to do wrong to He Ling. ”

But He Ling resisted desperately, making it difficult for the murderer to succeed, and finally in a hurry, the murderer stabbed He Ling. ”

"Let's just say that. It was not good for Gu Chen to completely reject Officer Wang's statement, after all, this might be consistent with the assumptions he had put forward before.

But it is unlikely that the murderer committed the crime without leaving a trace.

Gu Chen was convinced of this......

From the toolbox, Gu Chen took out the super glue and processed the power extension cord on the spot to find fingerprints.

But it's a pity that Gu Chen still didn't find what he wanted.

"It seems that the murderer committed the crime with gloves. After Gu Chen completed the on-site fingerprint collection, it was basically conceivable that the fingerprints collected in the room were actually very likely to come from He Ling's family or friends.

looked at He Ling's corpse again, the other rope wrapped around his neck.

Gu Chen found that it had been ripped from an old clock radio at the top of the stairs.

Gu Chen used super glue to treat it again, of course, including the ends of those shutter ropes, although there were also some very small hats, but after processing, he didn't find too many problems.

It can be said that Gu Chen has basically done everything he can do. Even all the imprints were compared, but the case was still clueless.

Lu Weiwei, who saw Gu Chen's concerns, comforted and said: "It's okay, these clues can't be done overnight, since the murderer is so cunning, he must also be a veteran, and he may pay special attention to the traces." ”

Looking at the several fingerprint samples that Gu Chen extracted, Lu Weiwei said again: "Besides, we have already extracted some fingerprints. ”

"Although it may not have much effect on the case, it can also be archived, and I will write the report if it is a big deal. ”

"Lu Weiwei, have you improved your consciousness?" Officer Wang saw that Lu Weiwei was like asking Gu Chen to share the pressure, and couldn't help but teasing: "Then I will also hand over my report to you to write in the future." ”

"Roll the calves. Lu Weiwei refused.

Although he could see that Gu Chen was not in a good mood, he didn't seem to have made much breakthrough in the collection of clues to the case.

So Lu Weiwei spoke very quietly, for fear of disturbing Gu Chen's analysis.

Gu Chen stood up straight, turned to He Qi and said, "Ms. He, you tap on the stolen items at home and give me a list of believers, the more detailed the better." ”

"Yes, I'll do it. He Qi endured his grief, took the pen and paper handed by Yuan Shasha, and began to tap the stolen items at the scene.

At the same time, Yuan Shasha also followed closely behind, reminding the matters that need attention.

It will take some time to complete all the checklist work.

But Gu Chen didn't urge.

For a full hour and a half, everyone was accompanying He Qi to tap the items.

The blank sticky notes gradually began to be full of details.

"Okay, that's basically all I remember missing, and if there's anything missing, I'll keep you informed. ”

He Qi handed the written details to Gu Chen.

Gu Chen nodded slightly, and reminded: "Don't live in this house first, and let your parents not come back first, in addition, we have to block the scene." ”

"I understand. He Ling knew that the police wanted to protect the scene and avoid secondary damage to the scene, so she agreed: "I'll give you the key, and then notify the family, can you see it?"

"Yes, thank you for your understanding and support. Gu Chen took the key handed by He Qi and said to Yuan Shasha: "Xiao Yuan, you are now going to pull a cordon, block the scene, and notify the nearby patrol team by the way, so that they can pay attention to the suspicious people around." ”

"Senior Brother Gu, what do you mean...... The murderer may still be at the scene?" asked Yuan Shasha.

Gu Chen nodded slightly: "Those who can clearly know the trajectory of this house should be acquaintances, and they chose to commit crimes late at night, so it is obvious that He Ling will not go home at that time." ”

Glancing at everyone, Gu Chen said again: "So the murderer committed the crime yesterday, and today may be near the scene, don't rule this out, let everyone not be lazy and lax, if you find any suspicious people nearby, go directly to interrogate, and you can ask a little bit." ”

"You know, it's just casting a net to catch fish. Yuan Shasha said with great conviction.
