traces of all things

Nowadays, the flow of information has also become faster. Ordinary people who pay a little attention to information about the rule of law know that fingerprints are unique evidence that can determine the identity of the murderer.Not to mention the young people who are on the cusp of the times.

It's just that fingerprints generally refer to the mastoid lines on the belly of the fingers.

At the scene where Zhan Jia and his family were killed, in fact, Lu Zheng and the others did not extract any fingerprints in the traditional sense at all, except for the fragments of nail polish with a little residual trace on it, that is, the parallel knuckle print.

Knuckle prints are different from fingerprints. Although theoretically everyone’s knuckle prints are different, our country does not have a database of knuckle prints, nor does it have an authoritative method for identifying identity. It can be observed by the naked eye of the appraiser.This evidence alone is not enough to convict. If Zhan Shengnan knows this piece of information and refuses to admit it, it will be troublesome.

Geng Zhizhong was very good at interrogation. He confused the difference between finger prints and knuckle prints quite old-fashionedly, and put some mental pressure on Zhan Shengnan.

Sure enough, when he heard that his fingerprints appeared at the crime scene, Lu Zheng noticed that Zhan Shengnan's fingers shrank obviously.

However, soon, Zhan Shengnan raised his head, with a calm face and a hint of disdain: "Uncle policeman, are you trying to extract a confession? That's my second uncle's house. What's wrong with fingerprints?"

Hey, this girl is quite quick-witted at critical moments.

Jiang is still old and spicy, although Geng Zhizhong is still expressionless at the moment, but Lu Zheng somehow feels that he is emitting a "hehehe" excited laughter in his heart.

It's like a seasoned hunter seeing his prey smartly avoiding one trap, but walking to another trap without knowing it.

"Of course there is nothing wrong with it." Geng Zhizhong looked straight at Zhan Shengnan calmly, with a square face exuding infinite coercion: "However, what if I said, your fingerprints were left on something that only the murderer touched?"

According to the part-time nanny who regularly goes to Zhan Jiahe’s house to clean, Zhan Mingfei’s cabinet of dolls is her darling, and no one is allowed to move it except herself, not even her mother Gong Yunlu.

Now Zhan Shengnan's face turned pale visibly to the naked eye.

Lu Zheng calmed down a little, knowing that it was only a matter of time before she opened her mouth, so he got up and walked out of the interrogation room without a sound.

In the corridor outside the interrogation room stood a young man in a white shirt, with a slender figure, fair complexion, and a handsome face.At this moment, he was carrying a briefcase in his hand, and his face was a little worried.

"Officer, how is Sheng Nan?" Seeing Lu Zheng coming out of the interrogation room, the young man's eyes lit up, and he stepped forward to ask quite nervously.

"The interrogation is not over yet, and the current situation cannot be disclosed." Lu Zheng waved his hand, and suddenly felt that the appearance of a young man looked familiar.

"Wait." He narrowed his eyes slightly: "Are you that President Wang's secretary?"

The young man was taken aback, as if he didn't expect that Lu Zheng still remembered him, and nodded hurriedly: "Yes, I was the one who called Zhan Zhan's secretary to ask why Zhan Zhan hadn't arrived yet. Talk to me."

"Well... Shengnan is my girlfriend." The young man said a little embarrassedly, while reaching out to shake Lu Zheng: "My name is Su Ming."

"Oh, that's how it is. You two look a bit like a couple." Lu Zheng nodded clearly. It seems that this person is the mysterious "dear" when Zhan Shengnan answered the phone in the inquiry room that day.

This Su Ming looks like a man and a woman, and he looks a bit like Zhan Shengnan. He is quite handsome with raised eyebrows, and he seems to be smart and tactful in dealing with people. Lu Zheng always feels that he and Zhan Shengnan's fierce Two- The painting style of dimensional girls is not consistent.

"It may take a long time to finish the inside." Lu Zheng estimated that Zhan Shengnan would be detained immediately after leaving the interrogation room, so he said to Su Ming rather tactfully: "Maybe it won't be finished today until evening. You'd better go back and wait, and the police will notify you when there is news."

"Okay, okay, thank you, officer." Su Ming nodded hastily, hesitated for a moment, and pulled Lu Zheng's sleeve with a slightly hesitant expression.

"Officer, I know Katsuo very well." He said earnestly, "She, a little girl, can't do such a cruel thing. Usually, she would cry in fright when she sees a bigger bug. She just Her ears are soft, she is easy to be coaxed by others, maybe she was deceived by someone..."

Seeing that he became more and more excited as he talked, Lu Zheng sighed and patted him on the shoulder, turned his body around and walked towards the hall at the end of the corridor.

"Don't worry, we won't let go of any criminals who shouldn't be let go. We won't blame any good people who shouldn't be taken away."

The Ninghai City Public Security Bureau has complete facilities, and the building occupies a considerable area, but the architectural design is a bit complicated. On the first day a few people from the special case team came, Daxiong almost lost his way.Now, if Su Ming were allowed to go out by himself, he would run into many walls.

Judging by his emotional and battered appearance, he probably has a good relationship with Zhan Shengnan, and he can't accept the fact that his girlfriend is a suspect for a while.Lu Zheng simply sent the Buddha to the west, a good man did it to the end, spread chicken soup for Su Ming all the way, and sent him out of the gate of the Public Security Bureau. After hearing that Su Ming didn't have a car, he kindly helped him call a taxi.

"Mr. Police Officer, thank you, you have really worked hard!" Before getting into the car, Su Ming was still chattering to express his worry and gratitude, holding Lu Zheng's hand and refusing to let go: "Please be sure to find out the truth, Once there is any new progress, I hope you can inform me as soon as possible."

Lu Zheng naturally nodded.

"Young man—! Comrade police—!" Suddenly, a broken voice yelled: "Have you finished talking! When can you get in the car!"

Lu Zheng lowered his head, and saw that the window of the passenger seat of the taxi had been rolled down at some point, and the taxi driver inside was twisting his body, stretching out his hand and waving at them, trying to increase his sense of presence.

"Hurry up and get in the car." Lu Zheng hurriedly helped Su Ming open the door of the passenger seat.

Su Ming also looked a little embarrassed, he quickly got into the car, and when the anxious taxi driver stepped on the accelerator, the green taxi disappeared into the traffic.

At the gate of the Ninghai City Public Security Bureau, under the shade of the plane tree, Lu Zheng stood for a long time, thoughtful.

What I can't get rid of in my mind is the white work gloves that were exposed when the taxi driver waved at him just now.

"Nobita, Shao Yuan." Lu Zheng rushed back to the temporary office assigned to them by the Ninghai Public Security Bureau: "Pack up your things, let's go."

At this time, Geng Zhizhong, Captain Tian Ziyao of Ninghai and others were still dealing with Zhan Shengnan in the interrogation room. In the office, only Wei Xiongfeng and Tang Shaoyuan were still studying the evidence at hand, trying to find out who was 1.7 in height. Clues to Mi Wu's male accomplice.

Hearing Lu Zheng's call, Tang Shaoyuan got up immediately, knocked down the materials on hand a few times, aligned them, and put them in a plastic folder.

"Where are you going, team leader?"

Different from Tang Shaoyuan's order and prohibition, Wei Xiongfeng looked a little confused, he was lifted out of the chair by Tang Shaoyuan, and he hadn't figured out the situation yet.

"Let's go to the bus company in Ninghai City. Or go to the largest taxi company in Ninghai City." Lu Zheng walked over excitedly and helped Wei Xiongfeng turn off the computer screen: "I have a clue about the male murderer, let's hurry up." Click, if you lock the suspect, you can also help the boss and put some pressure on Zhan Shengnan."

When Wei Xiongfeng heard that the other murderer also had a clue, he was so excited that he ran and bumped all the way downstairs, driving the car very fast.

The distance between Ninghai Taxi Co., Ltd. and the Municipal Public Security Bureau is not very far, and it takes about ten minutes to arrive.After showing his ID, Lu Zheng successfully met with a person in charge.

"Hi, excuse me. We are the criminal police of the Provincial Public Security Bureau." Lu Zheng reached out his hand and shook the person in charge. Without further ado, he went straight to the topic: "We are currently investigating a major criminal case, and we need to For the cooperation of your company, can you provide me with some old gloves worn by the taxi drivers of the company when driving? It is best to include the old gloves that have been used for different times, such as one month, three months, Half a year, and more than a year."

**

When the person in charge heard that it was a major criminal case, he was afraid of getting involved with his company, so he quickly notified many taxi drivers. Lu Zheng and the others did not wait long, and returned with six pairs of gloves provided by the taxi company. To the city bureau.

After returning to the Municipal Bureau, Lu Zheng immediately got into the laboratory of the criminal technology department. Under his command, Tang Shaoyuan and Wei Xiongfeng quickly prepared the required materials - a large stack of blank paper, and a bucket of A red pigment as thick as blood.

Lu Zheng arranged the six pairs of gloves in order. First, he picked up the one that had been used for a month and put it on. He dipped his left hand into the paint bucket lightly, aimed at a piece of white paper and wiped it neatly.

A blood-red glove mark instantly appeared on the paper.

Tang Shaoyuan and Lu Zheng had examined the physical evidence before, and it was immediately clear when they saw it: "This shape...is the bloody glove print on the wall."

"The answer is correct. Congratulations to our smart Dr. Tang, who has learned to rush to answer." Lu Zheng smiled and took off the first pair of bloody gloves on his hands, and moved the first blank paper. Tang Shaoyuan immediately took out the pen tacitly Came to stamp a "1" on this simulated glove.

After repeating this six times, Lu Zheng washed off what was left on his hands and dried them, then took out the photo of the bloody glove print on the wall and compared them.

When he compared to the third blank sheet of paper, he stopped, squinted slightly and read it over and over again.

After a few minutes, a look of excitement gradually appeared on his face, and his eyes shone brightly.

"Excellent." Lu Zheng murmured to himself, "Nobita, inform Boss Geng and Team Captain Tian that the male suspect has a clue."
