traces of all things

Hearing that it was a bloody glove print, Tang Shaoyuan looked a little disappointed: "There are no fingerprints."

"That's a good idea." Lu Zheng bent his fingers and knocked on the table in front of him: "These two murderers knew how to make fake shoe prints and cleaned up the crime scene. With such strong anti-reconnaissance capabilities, how could they not know how to wear gloves to commit crimes?" ?"

After finishing speaking, Lu Zheng picked up the live photo of the bloody glove mark again, and stared at it for a while.

Tang Shaoyuan on the side didn't speak, just looked at him quietly.

"I always feel," Lu Zheng muttered to himself while shaking his head gently, "this bloody glove mark is not that simple. This mark is not the same as that left by ordinary labor protection gloves."

Who will be the murderer?Lu Zheng looked at the intertwined and twisted lines in the photo, and countless blurry figures floated in his mind like a revolving lantern.

A man with a height of 175 cm and a medium build.

A thin woman with a height of 160 cm.

This question is currently unanswered.

Putting the glove marks aside, Lu Zheng decided to deal with the last few shirtless Barbie dolls.After finishing the DNA, Tang Shaoyuan also dragged a stool over to help with the painting.

Lu Zheng was proficient in doing this, and his hands were very fast. He did two or three kung fu, but Tang Shaoyuan was so clumsy that he didn't finish any of them.

"Hey, brother, what do you think this is?"

Lu Zheng regretfully put down the last Barbie whom he painted as a sexy black girl. When he turned his head, he saw Tang Shaoyuan standing aside, holding a brush in one hand, miraculously appearing on the doll's legs which had been swept black and black Three rectangular imprints side by side.

I go, what kind of good luck is this?

"You are amazing." Lu Zheng looked at Tang Shaoyuan in shock, grabbed his ungloved hand and rubbed it vigorously twice: "Where did this little red hand come from? Let me touch it." European gas."

His hands felt hot and soft for a moment, and Tang Shaoyuan felt that his legs also became hot and soft.

stand...can't stand...

Just as Tang Shaoyuan was struggling to mobilize his brain cells, thinking about whether he would fall into the chair cowardly or freeze in place, Lu Zheng mercifully released him, carefully took the doll to take a picture and fixed it, and then He took out the small measuring tape that never left his body from his pocket and measured it.

"The parallel knuckle print of the ring finger in the food center is 5 centimeters wide, with delicate edges and few rough edges. This is the parallel knuckle print of the right hand of a young woman aged between 18 and 25. Great, can you What a lucky star—hey, Shao Yuan, Shao Yuan? Why are you in a daze?"

**

The discovery of parallel fingerprints became one of the biggest gains of the task force that day.

On the other hand, Wei Xiongfeng was so busy all day that he hit the back of his head.

The extension of the surveillance video did not achieve much effect. He and several scouts found a van that appeared during a suspicious time period, but the quality of the surveillance video was not good, and the car had a fake license plate. After passing two intersections It was another monitoring blind spot, after which the investigators completely lost track of the suspect vehicle.

"These two murderers, the anti-reconnaissance ability is too strong!"

After Wei Xiongfeng finished complaining, he began to beam with joy: "But it's okay, Xu Lin's bank statement is a bit problematic, and 10 yuan was suddenly withdrawn this month. She claimed that it was borrowed from relatives who wanted to see a doctor, but we followed what she provided. I searched the information, and it's not that personal at all."

"Where is Xu Lin now?" Lu Zheng cheered up, and hurriedly asked.

"Please go and sit in the 'Tiger Chair'." Wei Xiongfeng took a sip of water, pretending to be deep: "I found a number in her call log that is closely related to her, and now I have found someone, called Sun Jiang, He is an unemployed vagrant, and recently a sum of 10 yuan suddenly appeared in his bank account. This person was dealt with by the public security organs because of a fight before, and he was brought in by the boss for interrogation just now."

It took a long time for Lu Zheng and Tang Shaoyuan. At this time, Geng Zhizhong had brought the duo of suspects into the interrogation room for quite a while.The few people had just finished communicating with each other outside, when they saw Geng Zhizhong coming from the other end of the corridor with a regretful face.

"How is it, boss?" Wei Xiongfeng asked impatiently.

Geng Zhizhong shook his head helplessly, and turned to look at Lu Zheng: "The interrogation went well. This Sun Jiang is not the murderer. He is over 1.8 meters five, with a foot size of 46. He is a burly man, which does not match the footprints at the scene of the crime." .”

"The 10 yuan is Xu Lin's payment to Sun Jiang for hiring a murderer. The deposit is [-] yuan, and more will be added later."

"Hire a murderer to kill someone? Was someone robbed him first?"

"No." Geng Zhizhong looked very speechless: "Originally Xu Lin hired Sun Jiang to kidnap Zhan Mingfei, the youngest daughter of the Zhan family. The plan is to act in a week."

"Oh my God." Wei Xiongfeng showed an unbearable face: "This little girl is really in a lot of trouble."

Sun Jiang and Xu Lin's suspicions were ruled out, and the investigation on Zhan Jia and Fang Zawqian was still in progress, and the case fell into a quagmire for a while.

A few people returned to the office and sat, Lu Zheng sat looking at the picture of the bloody glove print, Geng Zhizhong flicked through his notebook, Wei Xiongfeng typed on the keyboard, Tang Shaoyuan studied the autopsy on the table The report, the glasses are almost on the page in front of me.

With a bang, the door of the office was pushed open, and the short forensic doctor Xiao Wu, who was wearing size 39 shoes, appeared at the door.

Several people in the room raised their heads in a swish.

Under the gazing gaze, Xiao Wu's face flushed red.

"Lu, Team Leader Lu." Xiao Wu stammered a bit, but still made a sounding board very dedicatedly: "The report from Lihua has been done."

Lu Zheng took a thin piece of A4 paper from his hand, on which was printed a physical and chemical test report.

"...The main ingredients of the test object are nitrocellulose, acetone, ethyl acetate, etc. After identification, the test object is common nail polish in the market."

"Nail polish...?"

Lu Zheng felt a ray of light flashing through his mind, but he couldn't catch it no matter what.

"I'll go to the inspection room."

He hurriedly left such a sentence, and the person had disappeared behind the door.

**

In the material inspection room, Lu Zheng carefully took out a small box from the evidence bag.

Inside the small transparent plastic box were a few fine pieces of flakes, which were exactly the pieces that Lu Zheng found on the skirt of the Barbie doll that Lu Zheng took out from Zhan Mingfei's room.

According to the results of physical and chemical tests, these transparent little pink things are formed by the condensation and peeling of nail polish.

"Nail polish? So the murderer's finger is rubbed with transparent pink nail polish?" Lu Zheng said to himself: "No, why does ordinary nail polish come off so badly? And the lines on it ..."

The lines on the fragments made him have some special thoughts for a while. In the previous work, because he was not sure what the fragments were, he did not conduct further inspections on the fragments. Now is the time.

The criminal police brigade in Ninghai is in very good conditions, and all kinds of trace detection experimental equipment are complete. Lu Zheng pursed his lips slightly, while putting the glass slide on the microscope, and picked a mirror with a relatively large magnification to look inside.

He couldn't help but hold his breath as things in the circular lens became clearer and clearer.

Under the lens of a high-powered microscope, the imprints on the nail polish fragments were also reflected in Lu Zheng's pupils one by one.

The undulating lines, as well as several small protrusions that were invisible to the naked eye before, are evenly distributed on the edge and middle of the lines. According to the ratio, there are five or six per millimeter.

Lu Zheng has seen this thing not [-] times, but also [-] times during his several years of police career.

"Fuck! Fingerprints!"

**

Tang Shaoyuan in the office was still buried in his head trying to figure out some useful clues that had been missed from the autopsy report, when the door of the office over there was suddenly pushed open.

The one who came in was Lu Zheng who had just left for a while.

Seeing that his pair of black eyes were astonishingly bright, Tang Shaoyuan guessed that there should be some useful clues found on the remaining nail polish fragments. As expected, the first sentence of Lu Zheng striding into the office was shocking enough.

"Boss, Shao Yuan, Daxiong, finger lines and sweat pores were found on the nail polish fragments that were just inspected. This female murderer rubbed the nail polish on the pads of her fingers!"

Geng Zhizhong was so surprised that his black face glowed: "Is there any comparison value?"

The small flames in Lu Zheng's eyes shrank back: "No, the fragments are too small, and there is only one feature point on the largest piece. It is very difficult to eliminate."

Tang Shaoyuan couldn't bear to see him look disappointed, and was about to say something to comfort him, but was interrupted by Nobita on the side bluffing.

"Put nail polish on fingertips?" He protruded a round head from the computer screen in front of him: "The murderer must have watched Detective Conan, right?"

After all, he seemed to feel that the brain hole he opened up this time was even more unreliable, and he couldn't help but gawk, lowering his head and humming in his mouth: "Wait, wait, wait, wait, wait, wait... New Searching and digging many times for Sika (truth は一つしかない, there is only one truth)—”

While humming, he made the shape of a pistol with his fingers, and raised his head to gesture a classic action of a young elementary school student.

"—Nay."

Before the last two syllables were finished, Wei Xiongfeng was frightened silent by Lu Zheng and Tang Shaoyuan who suddenly stood up and stared at him.

"Sing it again!"

"Sing it again!"

The two said in unison as if they were completely synchronized.

**

"Raise your hands." Investigator Xiao Wu tried hard to keep his face on the ground, and said very seriously to the girl in the interrogation chair.

The girl on the chair was still the same as when she came to the police station for interrogation, wearing denim hot pants that were so short that they looked like she was not wearing pants from a distance.The temperature in the interrogation room was much lower than that in the interrogation room. A policewoman brought her a cardigan and covered her legs. The little girl lowered her head and didn't say thank you. She didn't know what she was thinking.

A few thin and white fingers rolled in the ink pad. Xiao Wu seriously extracted Zhan Shengnan's ten finger prints and palm prints, and also extracted her parallel knuckle prints according to Lu Zheng's special request. Once, and then handed it over to Lu Zheng.

Lu Zheng sat in a corner of the interrogation room, turned on the light, stuck an eye-mounted magnifying glass on his eyes, adjusted the angle, and compared them one by one.

His eyes flicked across textures, wrinkles, and planes. After a while, he raised his head and nodded to Geng Zhizhong, who had been paying attention to this direction.

"Ahem." Geng Zhizhong coughed and cut straight to the point: "Zhan Shengnan. We just met before, so we don't need to introduce each other. Please come to the interrogation room this time to cooperate with our investigation. My first question is, July Where were you from 7:23 a.m. to [-]:[-] a.m. on the [-]rd? Has anyone proved it for you?"

Zhan Shengnan raised his head for the first time.

Under the direct light, she looked haggard and her voice was a little hoarse.

"I'm sleeping at home. I live alone, no witnesses."

"Very good." Geng Zhizhong nodded, and continued to ask the second question in a cold voice.

"Then how do you explain that your fingerprints appeared at the scene of the murder of your second uncle's family?"

The author has something to say:

Hello Dakar, do you still remember the ringtone of Zhan Shengnan's cell phone the day he came to accept the inquiry?If you can’t remember, you can go back and watch Chapter 13, hehehe

In fact, rubbing nail polish on the belly of the finger to avoid leaving fingerprints is not very reasonable, because the nail polish on the skin is easy to peel off during violent movements. With the current criminal investigation technology, a little bit can be detected by physical and chemical professionals .If the dropped piece is larger, it will leave very clear fingerprints, residual epidermal cells, sweat, etc., leaving biological samples... So don't try to do it just because you have watched various film and television works. Bad thing, there are some plots in Conan that are quite nonsense hahahaha

ps I found that there is a little friend in the comment area who has been very sharp. The famous detective is you, but I won’t call the name to avoid spoilers. I will give you a thumbs up

Is this case over?Of course not, as a responsible author, how can you guess the answer so easily~ Welcome to continue watching O(∩_∩)O~
