traces of all things

For a while, several people in the evidence room looked at each other in blank dismay.

This victim is too unusual.

"Can't the DNA and fingerprints of this victim be found out? Can't be connected to the Internet?" Geng Zhizhong felt a little unbelievable: "The operation is so 'professional', it doesn't look like he has never dealt with the police."

"I have connected to the Internet with several provinces and cities in the south." Captain Cha Qing frowned into a dead knot: "There is another possibility that although the deceased had no criminal record, people close to her had relevant experience and were arrested. The police have dealt with it, and the deceased and this person are likely to be colluding in some wrongdoing, otherwise they would not be so careful."

"Xiao Li, I want to confirm that the engine number was scraped off by sharpening, right?"

Just when a group of people were a little overwhelmed, a clear boy rang.

Tang Shaoyuan turned his head subconsciously, and it really was Lu Zheng.I saw him leaning on the table with one hand at the moment, looking intently at Xiao Li in front of him.

"No, that's right." Xiao Li didn't expect to be cueed suddenly, so he quickly replied, took out his mobile phone from his trouser pocket and called up a picture: "The scratches are like this, I took a picture just in case. "

Lu Zheng glanced at the young investigator with surprise and approval, took the phone and observed it with a slight frown, and then his eyebrows relaxed.

"Captain Cha Qing, I have a way to find out the identity of the victim and the ownership of this car."

As soon as these words came out, the eyes of several people in the room were brightened, especially Captain Cha Qing, the thin and small man was as flexible as a little monkey in an instant, and rushed up one step at a time: "Tell me?"

"The first one is something that all our brothers can do together." Lu Zheng nodded at Xiao Li and the others: "The engine number is stamped on the engine cylinder by a coding tool. If you want to wear off the coding marks here, you need It is only necessary to have professional tools from a car dealership. We can start with various car repair shops in Yuanbao City. Polishing engine numbers is not a common job, and from this photo, the edges of the polishing traces are very sharp, and it was recently completed. , someone should have an impression of this."

Zha Qing nodded in agreement, and immediately winked at the investigator Xiao Li, who cleverly ran to organize the investigator's work.

"The other one is more direct, but it will take a little time." Lu Zheng smiled: "When I was studying last year, I heard about a new technology introduced by materialization, called metal flaw detection. The engine number is actually a coding tool in the machine It is formed by contact with the trace body under the action of external force. During the coding process, the crystal structure of the metal is destroyed by external force, the internal density changes, the structure is different, and the corrosion resistance will also change. Industrial CT Doing two-dimensional imaging can also process the worn out engine number, but the Municipal Bureau does not know if it has the corresponding equipment."

Needless to say, Captain Cha Qing was very excited.

The Yuanbao City Bureau started from both sides at the same time. A team of investigators went out to investigate various car repair shops. On the other side, Lu Zheng and the others carried the engine cylinder into the car with a grunt.

Naturally, the Yuanbao Municipal Bureau does not have such a professional thing as industrial CT, but fortunately, Yuanbao City is an industrial city with many metallurgical enterprises. The R&D department borrowed equipment.

The experiment was boring and time-consuming. After more than three hours of tossing, he finally got the desired result.

"It's been found." Lu Zheng found Captain Cha Qing, and handed him a developed picture and a stack of household registration information: "The owner of the car found based on the engine number is named Sheng Wenhao, 45 years old this year, Yuanbao A native of the city, he was cracked down by the public security organs for taking drugs the year before last, and he is still in a three-year community drug rehabilitation period."

At this time, the investigators sent out to investigate the car repair shop also returned smoothly.

"Captain, Team Leader Lu, we have found out that the original staff of Shunfeng Auto Repair Shop, No. 68 West Street, Baoshi, remembered that he had polished the engine number for an Audi car according to the boss's instructions a month ago. At that time, he still felt something was wrong. But didn't think much of it."

"The identity of the owner of this car dealership? Where is he?"

"The boss' name is Sheng Wenhao. According to the workers, the boss is very strange today. He didn't come to work, and no one answered the phone. Normally, he would show up in the car dealership every day."

**

Sheng Wenhao completely disappeared.

He lives alone and has no relatives. His mobile phone has no call records since that day and has been shut down all the time. His ID card information shows that he has not checked into any hotel that needs to be registered, and he does not have enough money to buy train or plane tickets. Nothing happened.

It was as if he had suddenly evaporated from this world.

Zha Qing refused to let go of this clue, and led the investigators to investigate Sheng Wenhao's social relations.

When Sheng Wenhao's sister was found, it was a little rewarding.

"Wen Hao has been alone since the divorce, but recently he seems to be talking about friends. Once I asked him to come to my house for dinner, and he couldn't say that he wanted to date his girlfriend." My sister Sheng Wenlan recalled some details when she was questioned. .

"Have you met his girlfriend? Do you still remember the name?" Lu Zheng's eyes lit up when he heard this, and he hurriedly asked.

Regrettably, Sheng Wenlan shook his head: "I haven't seen it. Wen Hao's brother-in-law doesn't like Wen Hao very much, and we have seen less in recent years, especially after his accident... that girlfriend seems to be called Chunhua."

This name again, Wei Chunhua, it seems that the deceased female also used a pseudonym when confronting her boyfriend.

Lu Zheng frowned slightly, feeling the difficulty of the case.

There was no trace of the major suspect, and the identity of the victim was unknown, and the case fell into the quagmire again for a while.

In the silence, Wei Xiongfeng suddenly spoke.

"Team leader, can we think about it from another angle? It's impossible for this fake Wei Chunhua to only have a relationship with Sheng Wenhao. Should we extend it from the video surveillance to see if she had any relationship with other people before she was shot?" touch?"

Lu Zheng's eyes lit up in an instant.

**

Although Wei Xiongfeng is always acting stupid, but at critical moments, he is quite able to find another way, and this suggestion was quickly unanimously approved by the Yuanbao City Bureau.

Yuanbao is probably because of the security problem. The size of the video surveillance room is as big as a large conference room. There are large screens on the entire wall, and there is a long table on one side, which is full of monitors. Just looking at this video monitoring room, Lu Zheng deeply realized how hard life is for the criminal policemen of Yuanbao City Bureau.

"The license plate number 15217 appeared near the parking lot of the hotel for the first time at [-]:[-]." With the help of investigators, Wei Xiongfeng retrieved the surveillance video of the road that must be passed near the crime scene: "The brother at the scene said , the monitoring probe in the parking lot is broken, there is no way to see the murderer, there are two roads leading to the parking lot, one is a two-lane road that can be used for traffic, and the other is a small alley. The car passed by, so the murderer probably did not drive, but entered the scene from a small alley."

Lu Zheng adjusted the speed of the video very slowly, almost watching it frame by frame.

The black Audi drove into the parking lot at [-]:[-], all the windows of the car were open, and it could be clearly seen that there was only the victim in the car. At about [-]:[-], the Audi drove into a The car slid out of the parking lot entrance at a very slow speed, the windows were still open, but the victim who was driving had his head down and seemed unconscious.

Then the security guard who called the police stepped forward to remind them that the car hit a tree and various chaotic scenes.

Nothing special, no suspicious people.

Lu Zheng nodded and motioned to Wei Xiongfeng: "Let's start extending the trajectory of the vehicle before the incident."

"Okay, no problem." Wei Xiongfeng put a pencil behind his ear, and tapped on the keyboard with both hands, only to see the scene on the screen constantly changing, and the camera shooting had changed to the road surveillance perspective.

"The outside of this parking lot is the downtown area, the main road of Yuanbao City, and there are a lot of Skynet surveillance on the road, which is not bad." Wei Xiongfeng looked at the surveillance video with more than one level of clarity in an instant with satisfaction: "It's still us Skynet is good."

Following the Skynet video, the two chased out of the downtown area and came to a relatively undeveloped place. After more than half an hour, the Audi car entered the blind spot of monitoring, and the video extension could no longer continue.

Wei Xiongfeng looked a little frustrated: "There seems to be nothing unusual along the way, and there are no suspicious vehicles or people following. The victim was alone in the car from the beginning to the end, and he didn't even make a phone call. Team leader, what now? What to do? — Team leader?”

Lu Zheng didn't realize it, as if he didn't hear what he was saying at all, he touched his chin with his right hand, pouted his lips slightly, and stared at the female face in the video.

The clarity of the Skynet camera is very touching, and the victim's fluttering long hair can be clearly seen through the windshield. The female victim has a mature charm, beautiful makeup, and bright red lips. When Qiuhu was in the morning, the sun was very hot in the morning. Not only did she wear sunglasses, but she also wore two sunscreen cool sleeves on her arms.

Wei Xiongfeng looked at the victim in the surveillance, and nodded self-consciously: "Leader, I know this victim is very beautiful, but time is precious, so let's hurry up."

Lu Zheng couldn't bear it anymore and gave him a chestnut.

Wei Xiongfeng was being aggrieved, Lu Zheng stretched out his hand to pat his head again, and muttered thoughtfully: "Daxiong, do you think there is something wrong with this victim?"

"Ah?" Wei Xiongfeng was really confused: "No?"

Lu Zheng shook his head, frowned again, turned his head to look around the room, and pinpointed the only female creature in the room—an investigator from Yuanbao City Bureau.

"Old girl, excuse me, I have a question."

As soon as the female investigator looked up, she saw that it was a handsome expert from the provincial department. Just for a second, her heart skipped a beat when she was heartbroken by his invincible and down-to-earth "old girl".

"Leader Lu, please tell me." She somewhat helplessly paused the video surveillance in front of her.

Lu Zheng scratched his head and thought about his words: "If you girls drive with the windows open, will it feel uncomfortable to blow your hair on your face?"

The female investigator was very sharp, and immediately got up and came to the side of Wei Xiongfeng and Lu Zheng, watching them play the video at a faster speed.

"It's really a bit strange." The female investigator frowned: "Why does she keep the windows open? And she's already driving. If you don't want to be exposed to the sun, you can close the windows. She also wears sun protection sleeves. It's a bit strange here. "

It became more obvious when the video was played at an accelerated speed. The wind blew in from the window, causing the victim's long hair to crackle and hit her face, and it stuck to her red lips from time to time. After a while, she would look unhappy. Dial it, seems impatient.

It's so unusual.

Lu Zheng couldn't help but fell into deep thought again.

Is there anything that requires her to keep the windows open during the nearly half-hour drive?
