745,Locard principle

A man who pretended to be someone else actually lived in a trailer, which shows that this guy has very high requirements for the quality of life.

At least it saves a lot of hotel expenses...

But for an unemployed young man, such a combination is still quite curious. Everyone can't wait to know what this man puts in the RV.

After getting the key handed over by the man, Gu Chen directly opened the door of the RV.

However, what is surprising is that the entire RV is full of surprises. From ancient objects, to retro electronic equipment, to gold and silver jewelry, there is almost everything.

Gu Chen turned on the law enforcement recorder and entered the RV to check.

All items in the RV are packed in transparent display boxes.

Although the space inside the RV is not large, it is like a small showroom.

Lu Weiwei and Yuan Shasha followed closely, while Officer Wang escorted the man and stood at the door of the car.

"Junior Brother Gu, look at this." Lu Weiwei found two vinyl CD cases at the bottom of a cabinet.

And this is exactly what He Qi provided in the list of stolen items.

Gu Chen put on his gloves, picked up the CD box and asked the man at the door: "Where did this thing come from?"

"I...I collected it," the man said.

Gu Chen asked again: "Do you like CDs?"

"No...that's right." The man choked, not daring to raise his head, and his eyes were filled with confusion.

Gu Chen snorted coldly, pointed at all the items in the RV and asked, "Don't tell me that all the items in this were obtained legally by you?"

"It's legal." Officer Wang asked the hunched-over man to stand up straight, and said with the crime tool in his hand: "Just this thing, do you expect him to obtain it legally? It can't be stolen, right?"

"I...I didn't, I didn't steal, I didn't steal." Seeing that Officer Wang believed that the items he displayed were stolen goods, the man immediately panicked and quickly denied it.

"And this, isn't this the stolen little golden Buddha that He Qi said?" At this moment, Yuan Shasha also found a small golden Buddha necklace in the drawer of the RV.

Since He Qi was at the scene at the time, when He Qi listed the stolen items with everyone, he also asked everyone to look at the small golden Buddha around his neck.

Originally there were two small golden Buddhas, one for each of the sisters.

He Ling usually likes to wear many accessories, so the little golden Buddha has always been left on the dressing table.

Therefore, when He Qi was taking inventory of her sister's belongings, she discovered that the small golden Buddha usually placed on the dressing table was missing, which also included two retro vinyl CD cases at home.

However, two of the stolen items that Gu Chen asked He Qi to list were found in the man's RV, which made Gu Chen suspicious.

Gu Chen saw the photos of the stolen items displayed by He Qi in the photo album of his mobile phone.

Moreover, He Qi also told herself that she and her sister He Ling once had two CD boxes.

However, there were no names on the CD boxes at the scene, and Gu Chen could not determine whether they belonged to He Qi and He Lin.

But Gu Chen could still accurately compare the items on site based on the pictures previously saved on his phone.

"Their exteriors are made of vinyl material, with many pebble-like protruding patterns." Gu Chen continued to flip the objects and said, "But it is difficult to extract fingerprints from this surface."

"Yes, we have tried this before, but the results were very unsatisfactory." Lu Weiwei also echoed.

After Gu Chen thought for a while, he added: "It doesn't matter. The bag inside the CD box may be worth trying."

"I can unfold them into the super glue chamber and see what we can get out of there."

"That's right."

Lu Weiwei nodded silently, not intending to do so at first, but then thinking about it, there were currently very few clues about He Ling's death, but the stolen items from He Ling's family were found in the RV. This was undoubtedly a chance.

If you touch it correctly, all the problems will be solved; if you touch it wrongly, you can at least catch the thief. After all, the items in this man’s RV are not very clean.

When thinking that the man in front of her might be the murderer of He Ling, Lu Weiwei would not give up any clues.

Therefore, Lu Weiwei took the initiative and said: "Let me get it and send these things to the Municipal Bureau's Technical Department for testing. The answer will be available soon."

"What should he do?" Yuan Shasha asked from the side.

"Take him to the Technical Section of the Municipal Bureau." Gu Chen said.

After everyone counted the items, Gu Chen called the nearby patrol team to take over, while he took his team members, the lost items from He Ling's house, and the suspect man back to the Municipal Bureau's Technical Section.

In the evening, Gao Chuanfeng was playing games in the office. When he saw Gu Chen bringing someone over, he immediately knew something was wrong. He quit the game and asked, "Is there anything I can help you with? Team Leader Gu."

"Help me extract this person's fingerprints. In addition, help me check the CD box thoroughly to see if there are any fingerprints. If so, help me extract them. The same goes for this little golden Buddha."

"I knew it would be bad to meet you Gu Chen late at night." Gao Chuanfeng was used to it.

Gu Chen's busyness is his own busyness.

Sometimes when dealing with Gu Chen, Gao Chuanfeng actually had a fulfilling life. At least Gu Chen was a tireless guy.

"Bring this person and everything to the testing room for me." Gao Chuanfeng straightened his shirt and then walked to the testing room with his head held high.

Officer Wang was escorting the man, and Yuan Shasha followed behind with items that needed to be tested.

Lu Weiwei chose to sit down next to Gu Chen.

Although the results haven't come out yet, Lu Weiwei looked at Gu Chen's indifferent expression and actually already had the answer in her heart.

"Junior Brother Gu, do you think this man is the one who killed He Ling?"

"Actually, there is no need to test. He is also the biggest suspect. The fingerprint test is just for double insurance." Gu Chen turned to look at Lu Weiwei and said:

"A forensic evidence scientist once said: Without exploration, there will be no discovery."

"But you know, Senior Sister Lu, we almost ignored those CD boxes. By the way, if these CD boxes hadn't been found in the RV, I wouldn't have easily thought that this guy might be the murderer of He Ling.

Although the test is still in progress, Gu Chen has actually predicted the results based on his own experience and judgment.

Verification is just to be more convincing.

Gu Chen knew that the results might not be detectable from the surface of the CD box, but the bag inside the CD box might be worth trying.

Any slight clue may bring unexpected gains.

Based on his own knowledge, Gu Chen actually already knew Gao Chuanfeng's next steps.

These CD cases can be put into the super glue compartment.

Gu Chen knew that this would have a dramatic effect, but it was also true.

Gu Chen learned everything from the forensic records...

According to Gu Chen's instructions, Gao Chuanfeng must inspect every bag in the first CD box in the inspection room.

But unfortunately, Gao Chuanfeng found nothing.

So Gao Chuanfeng began to test every bag in the second CD box.

At this time, Gu Chen also put on his equipment and stood next to Gao Chuanfeng, waiting quietly.

By the way, I will help Gao Chuanfeng.

But when he turned to the second to last bag, Gu Chen suddenly found a hair dyed red.

Recalling that He Ling had red hair before, Gu Chen became more cautious and excited at the moment.

It seems the truth is getting closer...

If this CD box was really stolen from He Ling's family, then this red hair must be He Ling's hair.

Gu Chen took out his mobile phone and took a photo of the hair to obtain evidence, then used long tweezers to carefully take it out.

The hair is intact and has roots, which is exactly what Gu Chen needs.

Afterwards, Gu Chen directly handed the hair sample to Gao Chuanfeng and warned: "Help me identify this hair to see if it belongs to He Ling."

"Yes, the workload has increased again." It felt like various tests came one after another throughout the night. Gao Chuanfeng's wish to sleep in was shattered, and he could only nod reluctantly:

"Okay, let's leave it for now. Code the number and fill in the sample test details. I'll do it together later. By the way, I'll compare it with the previous test of He Ling's body. Anyway, there are a lot of things to do tonight. I'll give you Gu Chen the rest of the night.

."

"That's good work." Gu Chen said with a smile, and then used long tweezers to hold the next CD bag in his hand and put it on a strong light source for inspection.

But at this moment, Gu Chen made a new discovery.

Gu Chen discovered that with the help of a special light source, there seemed to be a long fingerprint mark on the CD bag.

He had already read the autopsy report that Gao Chuanfeng had given to him before, especially He Ling's fingerprints. Gu Chen had browsed it many times, with pictures and detailed descriptions.

One of the hints is that He Ling's right ring finger fingerprint has a unique ribbing.

Therefore, Gu Chen relied on his expert memory to quickly extract the picture of the ring finger fingerprint on He Ling's right hand from the previous autopsy report from the information database in his mind.

As Gu Chen blinked twice quickly, Gu Chen used the visual editing function to quickly photograph the fingerprint mark with the help of a special light source and archive it in his mind.

Later, in the autopsy report, the fingerprint of He Ling's right ring finger slowly overlapped with the fingerprint picture she had just taken using the visual editing function.

But when the two pictures overlapped, Gu Chen surprisingly discovered that the special fingerprint on the CD bag exactly matched the fingerprint of He Ling's right ring finger.

The so-called unique ribbing also matches perfectly after overlapping.

Gu Chen almost laughed out loud. He threw the CD bag in his hand onto the testing table and said, "There are fingerprints on this bag, and it's the fingerprint of He Ling's ring finger on her right hand."

"You've found fingerprints before even testing? And it's He Ling's fingerprints?" Gao Chuanfeng was also stunned for a moment.

Although Gu Chen could always bring him unexpected surprises sometimes, after all, testing is a rigorous science and there is no room for sloppiness.

Gu Chen was talking nonsense in front of a professional like himself, and Gao Chuanfeng had to fight him no matter what for the sake of face.

But this is no longer important. Gu Chen has used his special ability to perform highly overlapping correction on these fingerprints, and there is no problem at all.

What Gu Chen needs is only the result. As for the process, he doesn't mind letting Gao Chuanfeng do it for him. This is also Gao Chuanfeng's responsibility.

After obtaining this information, Gu Chen was already confident that at least this CD box came from He Ling's family.

Therefore, now Gu Chen discovered that this suspicious guy actually possessed items stolen from the murdered He Ling's home.

From this point of view, this man has nothing to do with it.

Moreover, Gu Chen conducted a mitochondrial DNA test on the two hairs found at the crime scene to rule out the possibility that He Ling's mother and siblings had been at the scene.

What Gu Chen did was to see if these people had alibi.

But it is also true that on the night when He Ling was murdered, none of her family members were at the residence, and there were all witnesses.

Gu Chen already had enough evidence, and it would take time to wait for the test. Gu Chen couldn't wait any longer, so he directly called his team members and prepared to take the man back to the interrogation room of Furong Branch.

Seeing that Gu Chen had arranged for everyone to leave, Gao Chuanfeng, who was working hard in the testing room, glanced back and asked, "Gu Chen, aren't you here waiting for the results?"

"I already know what the results are. I'll take the suspect back to Furong Branch. When I get there, you should have the test results. Just send them to me." Gu Chen said.

Gao Chuanfeng smiled: "You are quite clever."

"Then I'll trouble you." Gu Chen walked to the door and paid attention to Gao Chuanfeng.

Then he took off his protective clothing outside the door and led everyone back to Furong Branch.

When I returned to Furong Branch, it was already 11 o'clock in the evening.

Many patrol officers on night duty at the Furong Branch have also come and gone several times.

Without further ado, Gu Chen directly called Officer Wang and Lu Weiwei to take the suspect back to Interrogation Room No. 1 of Furong Branch.

Yuan Shasha was responsible for staying in the third group office, waiting for Gao Chuanfeng's fax.

"Go in and do your best there." Officer Wang didn't have such a good temper. He directly pushed the man into the interrogation room No. 1 and pointed at the interrogation room.

The man looked around in panic, and he was also very nervous at this moment.

Whatever Officer Wang said, the man did not dare to refute and sat across from him obediently.

After Lu Weiwei adjusted the camera, she sat back next to Gu Chen, nodded and said, "Junior brother Gu, you can start."

"Okay." Gu Chen opened the transcript, raised his head and asked, "Tell me your name, age, and ID number."

"I...my name is Gao Desheng. I am 34 years old. My ID number is..."

Gao Desheng explained everything clearly according to Gu Chen's request.

After Gu Chen finished recording, he raised his head and asked again: "Why did you kill He Ling?"

"Wha...what? Should I kill He Ling? He...Who is He Ling?"

"Stop pretending." Gu Chen snorted coldly: "We already have sufficient evidence in our hands to prove that you were the murderer of that woman."

"Comrade policeman." Gao Desheng stood up anxiously and retorted directly: "You...don't just accuse people casually. Why did I kill someone? I didn't."

"Sit down." Officer Wang banged the table angrily, scaring Gao Desheng so much that he didn't dare to make a mistake, and he sat back down in his seat obediently.

Gu Chen curled his lips and smiled: "It doesn't matter if you don't tell me, I can help you sort it out."

Opening a page of information report, Gu Chen said: "You should have stolen that little golden Buddha, right? And that CD box."

"I..." Gao Desheng hesitated. He didn't know how to reply for a long time, but he still managed to say: "But how can you prove that it belongs to the deceased's family?"

"Nothing else." Gu Chen took out a printed color picture of the Little Golden Buddha and said, "This Little Golden Buddha is obviously He Ling's personal belongings, but it appears here with you. Why do you think it is here?"

"But...but there are so many small golden Buddhas of the same style in the world, why do you think they belong to the deceased?"

Gao Desheng seems to have been prepared...

From Gu Chen's difficulty in finding clues at the scene, it is easy to see that the murderer seems to be a master at clearing traces.

In many places that the police must inspect, it is obvious that someone left a hand and did not leave any traces of themselves on the scene.

Of course Gu Chen knew this, so he put down the color picture of the little golden Buddha and said, "It doesn't matter if you don't admit it, but how do you explain the CD box?"

"C...CD box? What's wrong with the CD box?" Gao Desheng raised his eyes, looking confident.

However, at this moment, Yuan Shasha held the faxed document and handed it directly to Gu Chen and said: "Brother Gu, the test report from Gao Chuanfeng of the Municipal Bureau's Technical Section has been released. I have sorted out the documents and they are all in

this."

"Thank you, Xiao Yuan, please sit down first." Gu Chen also calculated the time.

I know Gao Chuanfeng’s work efficiency very well.

Thinking that at this time, the test report should be coming out, and Yuan Shasha would send it over at the right time, Gu Chen stood up directly, took the test report, walked directly to Gao Desheng, and turned it over to him one by one.

.

"Did you see it?" Gu Chen smiled slightly and said calmly: "On the CD box, we found a red hair. After comparing it with the body of the deceased He Ling, it is completely consistent."

"And." After saying this, Gu Chen turned to another page of the test report and said: "And this, we extracted the fingerprints of the deceased He Ling from the bag containing the CD."

"This all shows that the small golden Buddha and the CD box were stolen items from He Ling's house."

"But the fingerprints we extracted from the scene were only He Ling's family members."

"After our investigation of He Ling's family, we found that they were not at the scene that night, but why did these items that were lost from He Ling's house appear in your RV? Why don't you explain it?"

"I……"

Hearing Gu Chen's words, Gao Desheng panicked and his face became stiff.

Gu Chen struck while the iron was hot and said: "Through these elimination methods, everyone has alibi, but you are the only one who can't explain why you showed up at He Ling's house at that time? Who is the murderer if it's not you?"

Gu Chen turned back to his seat and then said: "Gao Desheng, I can tell you that your case is a little different, because in the case, the order of many things is reversed."

"But it contains many elements of forensic evidence, such as...Locard's principle."
