8 p.m.

Technical Department of the Municipal Bureau, Testing Room.

Gao Chuanfeng has already started the overtime mode, and there are a lot of samples in his hand, all of which are test samples sent from major departments.

Previously, everyone was not optimistic about Gao Chuanfeng, thinking that this was just a fledgling forensic assistant, and sometimes he didn't even take care of it.

However, as Forensic Doctor Liu began to delegate power to Gao Chuanfeng, everyone gradually realized that Gao Chuanfeng seemed to be the successor of Forensic Doctor Liu.

The various tests with Forensic Doctor's acquiescence are enough to prove that Gao Chuanfeng is taking over many of the daily tasks of Forensic Doctor Liu.

Of course, this is not groundless, it was rumored earlier that Forensic Doctor Liu may be transferred out of Jiangnan City and go to work in colleges and universities in provincial capitals.

Such rumors have been spread several times, but they have not been confirmed, and Forensic Doctor Liu also confided that he will not leave the technical department of the city bureau for the time being until he finds a successor assistant.

Hands-on is Forensic Liu's style.

But now it is very different, many complex testing projects, Forensic Liu directly let the assistant complete.

Takakawa Kaede, in particular, seems to have more opportunities for independent testing.

It is precisely because Forensic Doctor Liu began to gradually take a back seat that this inevitably makes people suspicious that perhaps Forensic Liu has found a suitable successor.

Therefore, the previous various disapprovals, others may think that Gao Chuan Feng will not mind, of course, Gao Chuan Feng does not mind, but he just recorded it in a small notebook.

Gu Chen, Lu Weiwei and Officer Wang's Criminal Investigation Group 3 of the Furong Branch have always regarded Gao Chuanfeng as a friend.

Many cases were handed over to Takakawa Kaede, and he didn't seem to mind.

It is precisely because of this that when he received the same sample that needed to be tested, Gao Chuanfeng wanted to give Gu Chen priority.

This time is not unexpected.

When Gu Chen handed him the hair sample taken from Wang Dahu's head, Gao Chuanfeng was the first to make arrangements.

In addition, it was compared with the hair sample found in the hands of the deceased before, and it was quickly accepted.

"How is it?" Looking at the test form brought by Gao Chuanfeng and walked over, Gu Chen and Lu Weiwei, who were in the waiting room, immediately stood up and asked.

"The hair samples you sent before and after my meticulous examination found ...... It's really the same person. Takakawa said.

Lu Weiwei said in disbelief: "Oh my God, is the murderer really Wang Dahu? He is a friend of He Junchao." ”

"What if you get rid of the friend tag?" Gu Chen asked Lu Weiwei.

Lu Weiwei hesitated for a moment, and then said: "If you simply exclude the label of friends, it doesn't seem so surprising." ”

"So, Lu Weiwei, you determine whether a person is a murderer, and it is emotional?" Gao Chuanfeng threw the form into her hand and said with a smile: "As a policeman, you must look at the results independently and objectively, and you should not be swayed by acquaintances." ”

"Although the words are so, but ......" Lu Weiwei just wanted to say a few more words, but when the words came to her mouth, she suddenly ran out of words.

"Kaede Takakawa. Gu Chen glanced at him and continued to ask, "You should be okay with these tests, right?"

"There will be no problem. Gao Chuanfeng said in a two-hundred-percent tone: "All the testing steps, I strictly follow the way of Forensic Liu. ”

"As you can see from the tabular data of these tests, the match is extremely high, and in order to avoid mistakes, I even verified each hair separately, and the final result data is still the same. ”

"The hair samples you sent these two times are indeed the same person, I can guarantee that. ”

"Thanks, I see. After Gu Chen got Gao Chuanfeng's confirmation, the whole person seemed to agree.

But there was one thing Gu Chen didn't understand, why the scene was obviously cleaned up, and even all the items were neatly arranged, which didn't show any traces of a fight.

But such a thoughtful person, why did he make a mistake in the hands of the deceased Zhao Mengmeng?

Didn't he, Wang Dahu, know that Zhao Mengmeng had ripped off his hair when he resisted?

That's a bit of a stretch.

After all, it is very painful to rip off hair.

Normal people should know very well, but why didn't Wang Dahu realize it?

Or was he overly nervous at the time, and overlooked this while cleaning up other traces of the scene?

However, in Gu Chen's heart, what was not 100% sure of something, Gu Chen would not use it as absolute evidence.

This is the case now.

"Senior Brother Gu. Seeing that Gu Chen, who was holding the test form, was still in self-meditation, Lu Weiwei asked with some curiosity: "What's the matter?" Do you have any questions about Wang Dahu being the murderer?"

"That's right. Gu Chen also did not shy away from it, and directly said what he thought in his heart: "We have all been to see the scene, what do you think of Wang Dahu's level of cleaning up the scene?"

"This ......" Lu Weiwei didn't expect Gu Chen to ask this, and the whole person was also stunned.

But looking back, the scene at that time was indeed very clean, all kinds of items were neatly placed, except for Zhao Mengmeng who fell to the ground and was strangled to death, Lu Weiwei didn't even feel any traces of fighting and struggling at the scene.

"The site was deliberately cleaned. Lu Weiwei said with great certainty: "Even the floor tiles are clean, and there are no traces of struggle and friction." ”

"It can be said that the murderer has created a big problem for us, that is, the traces have disappeared, and it is impossible to judge what happened at that time, but on the contrary, we can deduce a scene at the scene. ”

"Yes. Gu Chen affirmed Lu Weiwei's statement, and asked: "It is such a thoughtful murderer who must clean up any clues, why did he let a few hairs fall into the hands of the deceased Zhao Mengmeng?

"Gu ...... Senior Brother Gu. Hearing Gu Chen say this, Lu Weiwei, who was not clear before, immediately realized from Gu Chen's side that it seemed that the situation was not as simple as she imagined.

"So, you mean, this seemingly unintentional clue is actually a hint that the murderer deliberately left us with the police?" asked Lu Weiwei.

Gu Chen nodded: "That's right, because it's too unreasonable, although we can easily find a few Wang Dahu's hairs from the deceased Zhao Mengmeng's hands, can this show that Wang Dahu is a murderer?"

"However, those hairs are indeed Wang Dahu's, what do you say about that?" asked Gao Chuanfeng, a forensic assistant.

Gu Chen clasped his hands to his chest, and after a moment of quiet hesitation, he said: "If the hair is Wang Dahu's, it makes me feel unbelievable, because to get the hair, you don't necessarily have to tear it off." ”

"Gu Chen, what do you mean......" Listening to Gu Chen's prompt, Gao Chuanfeng seemed to have thought of something, so he hurriedly asked, "What do you mean, it could also be Wang Dahu's own hair that fell out?"

"Yes. Gu Chen turned around and said with great certainty: "That's what I mean, the murderer may be able to collect some of the hair that he fell out of Wang Dahu's house in other ways." ”

"For example, the comb we use to comb our hair often leaves a drop of hair, if the murderer deliberately puts these hairs in the hands of the deceased Zhao Mengmeng, is the real murderer Wang Dahu?"

"Gu ...... Senior Brother Gu, you are simply too talented. Lu Weiwei listened to Gu Chen's explanation, and she was so excited that she didn't know what to say at the moment.

Gao Chuanfeng also admired and said: "Although my job is to provide technical appraisal support to your case handling team, we will speak with facts." ”

"But sometimes, the facts that the eyes see may only be the appearance, Gu Chen, you are right, what you said is completely possible. ”

"Kaede Takakawa. Gu Chen walked up to him and asked, "Where are the hair samples I gave you?"

"Inspection...... What's wrong with the testing room?" asked Takakawa Kaede.

"Can you show me again?" Gu Chen said.

Gao Chuanfeng sneered and laughed, "Gu Chen, do you not believe in my level?"

"It's not. Gu Chen said.

"Then what do you want a hair sample for?" said Takakawa again.

Gu Chen smiled: "Re-check and see if there is anything missing." ”

Originally, Gu Chen still hoped that the detected hairs were not consistent, but now it seems that the reasonable reasoning in many places needs to be torn down and reforged.

Gao Chuanfeng naturally knew that Gu Chen liked to get to the bottom of the case.

As long as there are doubts with different interpretations, he will definitely pursue them to the end, especially if he can't be sure whether it is evidence or not, let alone something.

"I've heard Forensic Doctor Liu say a long time ago that you, Gu Chen, may be the best policeman he has ever seen, and he didn't use one of them to describe you, I feel that you are just different from other policemen. ”

"But when I asked Forensic Doctor Liu, what is different about your Gu Chen, Forensic Doctor Liu told me that it is persistence and seriousness, especially in terms of work, these two characteristics are particularly prominent. ”

"Compared with other police officers, they often hope that our technical department will not only help them identify the results they need, but also help them solve problems through our technical identification. ”

"But you are not like Gu Chen, you are in charge of the case throughout the whole process, and our forensic doctor has become your assistant. ”

"Haha, it's not that serious, right?" Gao Chuanfeng didn't say anything, and Gu Chen didn't know what kind of image he had in the eyes of their forensic doctors.

"So...... Those two hair samples?" Gu Chen asked again.

"I'll take you there. "What else can Gao Chuanfeng say? I can only take Gu Chen and Lu Weiwei to the testing room together.

After stepping on the switch with his foot and opening the air valve, Gao Chuanfeng took the hair samples sent before and after to Gu Chen.

At this moment, the hair was placed on a white paper and wrapped in a transparent forensic bag.

Gu Chen first put on white gloves, and then, in chronological order, first took out the hair extracted from the deceased Zhao Mengmeng's hand, put it under a strong light, took out a magnifying glass, and repeatedly observed the hair.

Lu Weiwei was like a serious elementary school monk, standing behind Gu Chen, stretching her neck from time to time to observe the details.

After Gu Chen completed the testing of the first hair sample, Gu Chen took out the second hair sample, that is, the hair sample that Wang Dahu personally took from his head, which was also placed under a strong light, and picked up a magnifying glass to observe it carefully.

Different from the first observation, Gu Chen quickly found the abnormality when he tested it for the second time.

"Not true. Gu Chen suddenly frowned.

Gao Chuan Kaede didn't know why and said, "What...... What's wrong? You're saying I'm not doing the right thing?"

"It's not that you're testing the wrong thing, it's that the hair sample isn't right. ”

Listening to Gu Chen's ambiguous reply, forensic assistants Gao Chuanfeng and Lu Weiwei were stunned.

After the two looked at each other, they didn't understand what Gu Chen meant.

"Senior Brother Gu, aren't these two hair samples Wang Dahu's? Why did you detect something wrong so quickly? Could it be that there was a mistake in Gao Chuanfeng's previous test?"

"That's not what it means. Gu Chen turned around directly and said with a smile: "Previously, we had two hair samples that were sent to the technical department one after another, so there was no comparison. ”

"But now it's different, two hair samples are in front of you, and you can see at a glance if there is anything abnormal. ”

Lu Weiwei frowned slightly, hurriedly walked in front of Gu Chen, and began to carefully observe the two hair samples.

Soon, Lu Weiwei also found something suspicious: "Senior Brother Gu, what do you mean...... The length of the two hair samples is inconsistent?"

"Huh?" When Gao Chuanfeng heard this, he also hurried closer, and then said: "It seems that yes, I didn't pay much attention to it before, and the hair sample you sent behind was indeed a little different from the one sent before." ”

Afterwards, Gao Chuanfeng also walked in front of the sample, pointed to the hair sample sent before, and said, "This is the hair sample you took from the deceased, and the sample sent by the two of you personally afterwards is obviously much longer." ”

"That's right. Gu Chen nodded, and said affirmatively: "Wang Dahu, I have met Lu Weiwei, he had a haircut yesterday, and he also over-permed his hair, the length of his hairstyle is obviously more representative of the hair samples we brought later, because it is only so long." ”

Gao Chuanfeng turned his head to look at the second hair sample, and then hurriedly looked at the first hair sample, and then suddenly realized: "So, this Wang Dahu shouldn't have such long hair since yesterday, right?"

"Yes. Gu Chen picked up the first hair sample and said: "The hair dragged by the deceased Zhao Mengmeng's hand has a round end, which means that the owner of the hair has not had a haircut for a long time, which also confirms Wang Dahu's previous hairstyle." ”

"But look at this second hair sample. Gu Chen took the hair sample taken by Wang Dahu himself to everyone and said, "See, the ends of the hair are flat, because Wang Dahu just got a haircut yesterday, so the ends of the hair are flat." ”

"But the deceased Zhao Mengmeng, she was killed today, so I deduce that the murderer should have stolen Wang Dahu's hair before his haircut and stuffed it into Zhao Mengmeng's hands, trying to frame Wang Dahu in an attempt to achieve the purpose of diverting the attention of our police. ”

Hearing Gu Chen's words, forensic assistants Gao Chuanfeng and Lu Weiwei also hurriedly checked the two samples one by one according to Gu Chen's words.

As Gu Chen deduced, the hair tips of the hair samples in the deceased's hands were obviously round, while the tips of the hair in the second sample were obviously flat.

Although it may not be easy to distinguish such a difference with the naked eye, if you look at it with a magnifying glass, the situation will be clear at a glance.

"It's horrible. Lu Weiwei saw that she took it like this, and the whole person also gasped: "This murderer, after the murder, actually used Wang Dahu's hair to seriously divert the attention of our police. ”

After thinking about it, Lu Weiwei said again: "Oh no, since it is the hair in the hands of the deceased, it is the hair before Wang Dahu's haircut, but he didn't perm his head before the haircut, but why is the hair in the hands of the deceased Zhao Mengmeng obviously showing traces of perm?"

"Lu Weiwei. Gao Chuanfeng saw that Lu Weiwei didn't know why, and he also felt that Lu Weiwei didn't seem to have jumped out of her fixed thinking, so he helped Gu Chen explain:

"It shouldn't be difficult to perm a few strands of hair to have the look of a tin foil perm, just treat those hairs. ”

"That's right. Gu Chen also explained with a smile.

"So that's the case?" she glanced at Gu Chen, and then said happily: "Senior Brother Gu, if it weren't for you, this Wang Dahu might have to be wronged, it seems that the case should be handled carefully and carefully, especially the judgment of the authenticity of the clues." ”

"Maybe most of the time, the murderer is just hiding clues, but it's much more clever to fake clues. ”

Gu Chen also smiled faintly: "Actually, it's nothing, there are many cases handled, for this kind of clues that are too obvious, and there is an obvious contrast with the surrounding environment, I will ask myself, is the situation I saw really like this, so I will find these suspicious points." ”

"Gu Chen. "Forensic assistant Gao Chuanfeng has already admired the five-body cast at this moment.

He directly gave a thumbs up and said: "Your guy's observation power is really beyond the reach of ordinary people, and I haven't found any problems, but you can see through it at a glance, and you really have you." ”

"So now?" asked Lou.

"Immediately return to the interrogation room of the Seremban substation to investigate the suspect who can collect Wang Dahu's hair. Gu Chen said.

......

......

9:20 p.m.

Gu Chen and Lu Weiwei returned to the interrogation room with the results of the latest investigation.

At this moment, Wang Dahu almost fell asleep.

And Officer Wang is no different.

Because Wang Dahu was detained in the interrogation room, He Junchao also came to ask about the situation.

When he learned that his good brother Wang Dahu might be the murderer, He Junchao almost collapsed.

Standing outside the interrogation room, he fought with Officer Wang for 300 rounds, and was persuaded to retire and go back to the police dormitory first, and report the situation at any time.

I also saw Gu Chen and Lu Weiwei return to the interrogation room.

Officer Wang, who was eating noodles at the moment, quickly put down his chopsticks and asked with a smile: "Gu Chen, Lu Weiwei, what are the results of your investigation? Is the hair in the deceased's hand Wang Dahu's? His brother He Junchao is also waiting for the result, you can talk about it." ”

After Gu Chen and Lu Weiwei looked at each other for a short time, Wang Dahu, who was on the opposite side of his hairstyle, also stopped eating noodles at this moment.

seemed to be waiting for his innocence, and his expression was much calmer than when he first entered the interrogation room.

"Yes, Officer Gu, Officer Lu, is the hair sample already out? Am I innocent?" Wang Dahu smiled innocently, picked up the chopsticks in his hand, and was about to send noodles to his mouth.

As a result, Lu Weiwei was stunned and choked the noodles that Wang Dahu had just put in her mouth: "Don't hide it from Wang Dahu, these two hair samples are yours." ”

......
