I am a super cop

Chapter 553 Take advantage of the head [seeking monthly ticket]

8 pm.

Municipal Bureau Technical Section, Testing Room.

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

Previously, everyone was not optimistic about Gao Chuanfeng, thinking that he was just a fledgling forensic assistant, and sometimes even ignored him.

However, as Liu Fayi began to delegate power to Gao Chuanfeng, everyone gradually realized that Gao Chuanfeng seemed to be Liu's successor.

The various tests with Liu's forensic acquiescence are enough to prove that Gao Chuanfeng is taking over many of Liu's daily work.

Of course, this is not groundless. It has been rumored earlier that Forensic Liu may be transferred from Jiangnan City to work in a university in the provincial capital.

Such rumors have been spread several times, but have not been confirmed. Moreover, forensic doctor Liu also revealed that he will not leave the technical department of the Municipal Bureau until he finds a successor assistant.

Doing it yourself is Liu's style of forensic medicine.

But now it is very different. For many complicated testing items, Forensic Doctor Liu let the assistant complete them.

Gao Chuanfeng, in particular, seems to have more opportunities for independent testing.

It is precisely because Liu Forensic has gradually retreated to the second line, which inevitably makes people suspect that perhaps Liu Forensic has found a suitable successor.

Therefore, others may think that Gao Chuanfeng would not mind the previous dislikes. Of course, Gao Chuanfeng did not mind, but he just recorded it in a small notebook.

Gu Chen, Lu Weiwei, and Police Officer Wang's Criminal Investigation Team [-] of the Furong Sub-bureau have always regarded Gao Chuanfeng as friends.

Many cases were handed over to Gao Chuanfeng, and he didn't seem to mind.

It is precisely because of this that when receiving the same sample that needs to be tested, Gao Chuanfeng has always given Gu Chen priority.

No surprise this time.

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

Coupled with the comparison with the hair samples found in the hands of the deceased, the results were soon available.

"How is it?" Gu Chen and Lu Weiwei who were in the waiting room immediately stood up and asked after seeing the test form Gao Chuanfeng brought over.

"The hair samples you sent before and after, after my careful inspection, I found that...these are indeed from the same person." Gao Chuanfeng said.

Lu Weiwei said in disbelief: "My God, could it be that the murderer is really Wang Dahu? He is He Junchao's friend."

"What if the friend label is removed?" 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 judge whether a person is a murderer or not, is it 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 judged by others." Around acquaintances."

"That's the case, but..." Lu Weiwei was about to say a few more words, but she suddenly ran out of words.

"Gao Chuanfeng." Gu Chen glanced at him, and continued to ask: "Your tests should be fine, right?"

"There will be no problem." Gao Chuanfeng said in a [-]% tone: "I carried out all the testing steps in strict accordance with Liu Forensic's method."

"From the table data of these tests, you can also see that the matching degree 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 twice are indeed from the same person, I can guarantee that."

"Thank you, I see." After Gu Chen got Gao Chuanfeng's confirmation, he seemed to agree.

But there was one thing Gu Chen didn't understand, why the scene was clearly cleaned up, and even all the items were neatly arranged, so there was no trace of a fight at all.

But it was such a thoughtful person, why did the deceased Zhao Mengmeng make mistakes in his hands?

Didn't he, Wang Dahu, know that Zhao Mengmeng once tore off his hair when he was resisting?

This is somewhat unreasonable.

After all, pulling hair out is very painful.

Normal people should be very clear about it, but why didn't Wang Dahu realize it?
Or was he overly nervous at the time, and neglected this point when cleaning up other traces of the scene?It seems to be the past.

However, in Gu Chen's mind, if there is something that cannot be 100% sure, Gu Chen will not regard it as absolute evidence.

This is the case now.

"Junior Brother Gu." Seeing that he was still in self-meditation, Lu Weiwei asked curiously, "What? Do you have any doubts about Wang Dahu being the murderer?"

"That's right." Gu Chen didn't shy away from it, and directly expressed his thoughts: "We've all been to the scene, what do you think of Wang Dahu's level of cleaning up the scene?"

"This..." Lu Weiwei never thought that Gu Chen would ask this, and she was stunned for a moment.

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

"The scene was cleaned up on purpose." Lu Weiwei said with certainty, "Even the floor tiles are clean, and there are no traces of struggle or friction."

"It can be said that the murderer created a big problem for us, that is, the traces disappeared, and it was impossible to judge what happened at that time. On the contrary, we can infer a scene."

"Yes." Gu Chen affirmed Lu Weiwei's words, and asked again: "It is such a meticulous murderer who has to clean up any clues, why did he let a few hairs fall into the hands of the deceased Zhao Mengmeng? Could it be that the murderer I don’t know, is this undoubtedly a clue for our police investigation?”

"Gu... Junior Brother Gu." Hearing what Gu Chen said, Lu Weiwei, who hadn't understood the reason before, immediately realized from Gu Chen that the situation was not as simple as she imagined.

"So, what do you mean, this seemingly unintentional clue is actually a tip left by the murderer to our police?" Lu Weiwei asked.

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

"But, those hairs are indeed Wang Dahu's, so what do you say?" Forensic assistant Gao Chuanfeng asked.

Gu Chen folded his hands on his chest, hesitantly hesitated for a moment and then said: "If the hair belongs to Wang Dahu, it makes me feel unbelievable, because to get the hair, you don't have to tear it off."

"Gu Chen, what do you mean..." Hearing Gu Chen's prompt, Gao Chuanfeng seemed to have thought of something, so he hurriedly asked, "You mean, it might be Wang Dahu's own hair that fell off?"

"Yes." Gu Chen turned around and said with certainty: "That's what I mean, the murderer may be able to use other methods to collect some of the hairs he fell from Wang Dahu's house."

"For example, the comb we use to comb our hair often leaves some hair that fell out. If the murderer deliberately put these hairs in the hands of the deceased Zhao Mengmeng, could the real murderer be Wang Dahu?"

"Gu... Junior brother Gu, you are simply too talented." Listening to Gu Chen's explanation, Lu Weiwei was so excited that she didn't know what to say.

Gao Chuanfeng was also full of admiration: "Although my job is to provide technical appraisal support for your case handling team, we will speak with facts."

"But sometimes, the facts seen by the eyes may be just appearances. Gu Chen, you are right. What you said is completely possible."

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

"Testing... the testing room? What's the matter?" Gao Chuanfeng asked.

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

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

"No." Gu Chen said.

"Then what do you want a hair sample for?" Gao Chuanfeng asked again.

Gu Chen smiled: "Check again 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 overthrown and recast.

Gao Chuanfeng naturally knew that Gu Chen always 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 is not sure whether they are evidences or not, let alone something.

"I've heard from Forensic Doctor Liu that you, Gu Chen, may be the best policeman he has ever seen, and he didn't use 'one' to describe you. It feels like you are different from other policemen."

"But when I asked Fayi Liu, what is different about you and Gu Chen, Fayi Liu told me that it was persistence and seriousness, especially when it comes to work. These two characteristics are particularly prominent."

"Compared to other police officers, they often hope that our technical department will not only help them identify the results they need, but also hope that through our technical identification, they can help them solve real problems, including reasonable reasoning."

"But Gu Chen, you are different. You are leading the whole process of the case, and our forensic doctor has become your assistant."

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

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

"I'll take you there." What else could Gao Chuanfeng say?He could only bring 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 gave Gu Chen the hair samples sent twice before and after.

The hair at this moment was placed on white paper and wrapped in a transparent evidence collection bag.

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

Lu Weiwei stood behind Gu Chen like an elementary school monk who was seriously observing, stretching her neck to observe the details from time to time.

After Gu Chen completed the test of the first hair sample, Gu Chen took out the second hair sample, which was the hair sample Wang Dahu took from his own head. Observed.

Different from the first observation, Gu Chen quickly discovered the abnormality during the second inspection.

"No." Gu Chen frowned suddenly.

Gao Chuanfeng didn't understand, so he said: "What...what's wrong? You mean that my test is wrong?"

"It's not that your test is wrong, but the hair sample is wrong."

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.

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

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

"But it's different now. Two hair samples are right in front of you, and you can tell at a glance whether there is any abnormality."

Lu Weiwei frowned slightly, and hurried to Gu Chen, and began to carefully observe the two hair samples.

Soon, Lu Weiwei also found something suspicious: "Junior Brother Gu, what do you mean...the lengths of the two hair samples are not the same?"

"Huh?" Gao Chuanfeng hurriedly got closer when he heard it, and then said again: "It seems to be true. I didn't pay much attention to it before. The hair samples you sent later are indeed somewhat different from the ones sent before."

Afterwards, Gao Chuanfeng also walked up to the sample, pointed to the hair sample sent earlier and said: "This is the hair sample you took from the deceased. It is obviously much longer than the sample you sent yourself later."

"That's right." Gu Chen nodded, and said with certainty: "I have met Wang Dahu and Lu Weiwei, he had his hair cut yesterday, and he also permed his head, the length of his hairstyle is obviously more representative of the hair samples we bring later , because it's only so long."

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

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

"But take a look at this second hair sample." Gu Chen brought the hair sample that Wang Dahu personally took out in front of everyone and said, "See? The ends of the hair are flat, because Wang Dahu just had his hair cut yesterday, so The ends are flat."

"But the deceased, Zhao Mengmeng, was killed today, so I infer that the murderer stole Wang Dahu's hair before a haircut, and stuffed it into Zhao Mengmeng's hands, in an attempt to frame Wang Dahu and divert the attention of our police. the goal of."

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

As Gu Chen deduced, the hair sample in the deceased's hand had obviously round ends, while the second sample had obviously flat ends.

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

"It's terrible." Lu Weiwei gasped when she saw this result, "This murderer actually used Wang Dahu's hair to divert the attention of our police after the murder."

After thinking for a while, Lu Weiwei said again: "Oh, that's not right, since the hair in the dead man's hand was the hair before Wang Dahu's haircut, but he didn't perm his head before the haircut, but why the hair in the dead Zhao Mengmeng's hands is obviously permed What about traces?"

"Lu Weiwei." Seeing that Lu Weiwei didn't understand, Gao Chuanfeng also felt that Lu Weiwei didn't seem to have jumped out of the fixed thinking, so he helped Gu Chen explain:
"It shouldn't be difficult to perm a few hairs to look like a tin foil perm hairstyle. You just need to deal with those few hairs."

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

"So that's the case?" She glanced at Gu Chen, and said fortunately: "Junior Brother Gu, if it weren't for you, this Wang Dahu might have been taken advantage of. It seems that we should be careful in handling the case, especially for the clues. false judgment."

"Perhaps most of the time, the murderer is just hiding clues, but forging clues is much smarter."

Gu Chen also smiled slightly: "Actually, it's nothing. There are too many cases handled. When there is a clear contrast between such obvious clues and the surrounding environment, I will ask myself, is what I see really true?" Is that so? That’s why I discovered these doubts.”

"Gu Chen." Forensic assistant Gao Chuanfeng was already in admiration at this moment.

He directly gave a thumbs up and said: "Your observation ability is really beyond the reach of ordinary people. I didn't even notice the problem. You can see through it at a glance. You really have it."

"So now?" Lu Weiwei asked.

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

……

……

9:20pm.

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

At this moment, Wang Dahu was almost falling asleep.

The same is true of Officer Wang.

Since 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 had three hundred rounds of tongue-in-cheek wrangling with Police Officer Wang. He was persuaded to retreat and go back to the police dormitory. He Junchao then agreed to leave and ordered noodles for the two of them.

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

Police officer Wang, who was eating noodles at the moment, quickly put down his chopsticks, and asked with a smile: "Gu Chen, Lu Weiwei, what is the result of your investigation? Is the hair on the dead man's hand Wang Dahu's? I’m also waiting for the result, but you can talk about it.”

After Gu Chen and Lu Weiwei looked at each other briefly, they found that Wang Dahu, who was opposite him, also stopped eating noodles at this moment.

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

"That's right, Officer Gu, Officer Lu, have the results of the hair sample been produced? Am I innocent?" Wang Dahu smiled innocently, picked up the chopsticks in his hand, and was about to put noodles into his mouth.

As a result, Lu Weiwei choked up the noodles that Wang Dahu had just put into his mouth in a daze, "To tell you the truth, Wang Dahu, these two hair samples belong to you."
