Xu Dayuan went to check the people, and Zhou Ning and the others hurriedly checked the two cars.

Touching the Volkswagen CC, Zhou Ning thought in his heart and submitted a temporary task: This is the vehicle that caused the accident.

After waiting for a while, the system did not respond at all.

It's not like the first time the task is submitted, it jumps out and says that the task is submitted successfully, and the reward is drawn, what is the reason for this, I answered wrong?

This idea was directly overturned by Zhou Ning, if he was wrong, according to the urine nature of this system, he would have jumped out and downgraded the previous reward.

When you think about it, this temporary assignment seems to have two requirements.

That is to find the vehicle and the perpetrator who hit and injured the dead, it seems that it was hasty, and he didn't think about submitting the first mission, but the idea popped up in his head, and the task was over.

Zhou Ning's eyes flashed, that is to say, the current answer is not wrong, but it is not standard enough, or rather, his answer is right, but it is not comprehensive enough, and there is a lack of evidence.

Didi, after thinking twice in her ears, a task submission page popped up on the transparent display, and three conditions appeared on it.

Evidence?

Drivers?

The vehicle that caused the accident?

Zhou Ning made a mistake, I went to do so, you are a pit in a pit, if I didn't analyze it myself, this task would not have been submitted, after all, this submission page was not opened.

With a sigh, Zhou Ning looked at the criminal policemen who were circling around the car, Zhao Xinli had already taken down the investigation box and distributed the things.

There is no technical content in collecting fingerprints, but he is careful, Zhou Ning is not in a hurry to get into the car, the door handle, the window, the upper edge of the door, and the central control switch are all places that can be touched by opening and closing the door, Zhou Ning carefully swept it with a brush dipped in special powder.

Several fingerprints appeared, and Zhou Ning carefully extracted them.

"Forensic doctor Xiao Zhou, I also found a few fingerprints here."

Zhao Xinli knelt on the co-pilot of Nissan, with an isolation suit under his knees, and sure enough, there were fingerprints and palm prints on the gear handle.

Zhou Ning carefully extracted it, held the collected things, and looked at the Volkswagen CC on the side, the three people in the car were searching, why was there no movement at this time?

Throwing things to Zhao Xinli, Zhou Ning walked towards Volkswagen CC.

"Nothing found here?"

"I found a few fingerprints of gloves, and I didn't find anything else, it seems that this car has been carefully cleaned, and the interior has been cleaned with a smell."

Zhou Ning was a little dumbfounded, the car had been repaired, and the interior had been cleaned so thoroughly, how could it be proved that this car was the vehicle that caused the accident?

Pushing the door and getting out of the car, Zhou Ning stood in front of the car and looked at the car carefully.

"Brother Zhao, in 24 hours, to repair a car that was in an accident to such a brand new state, do you think it is possible?"

Zhao Xinli shook his head decisively.

"I can't."

"Can't?"

Zhou Ning was stunned, Zhao Xinli hurriedly opened the engine cover, pointed inside and said.

"Don't worry, if you do sheet metal painting, you can't finish it, I looked inside, the engine cover and the screws in these places have no traces of twisting, indicating that these have not been replaced, the deceased is not a broken calf, that is, the high speed of the car hit the deceased's leg, directly lifted the person out of the flight.

If this is the case, the damage to the car is not serious, just replace the bumper and headlights, which can not see any traces, of course, if we find the same car to replace us, we can't see it, as for the tires, I see that they have also been replaced. ”

Zhou Ning pushed his glasses, and the image found by the deceased at the first scene appeared on the transparent display screen, and it kept rotating, Zhou Ning stared at the glass ballast on the deceased's cheek and slowly shook his head.

"No, the deceased not only fractured the tibia and fibula of her left leg, but also had glass shards on the left side of her face and bruises on her eye socket, which means that after being hit on the leg, she hit the side of her head on the glass."

When Zhao Xinli heard this, he leaned on the corner of the windshield from the side, held a magnifying glass and looked there for a long time, and his eyes lit up instantly.

"Awesome Xiao Zhou Forensics, this windshield has indeed been replaced, although this is the original glass, but the production date is wrong!"

This discovery made Zhou Ning silent.

The windshield, bumper and headlights were replaced, and if these replaced things were destroyed and the suspect still refused to admit it, then the car could not be identified as the vehicle that caused the accident, and it could only prove that the two were involved in illegal racing, and they must have missed something.

Zhou Ning stood in front of the car, and didn't speak like this for a few minutes, a few criminal policemen seemed to want to say something, but they were stopped by Zhao Xinli, he could be regarded as understanding the temper of this Xiao Zhou forensic doctor, it was not a bad thing for him to fall into contemplation, maybe there would be a good way in a while.

Zhou Ning, who was contemplative, suddenly lit up when he thought of the wound between the deceased's ribs and the on-site sampling content he learned last night.

Zhou Ning moved, found a bottle of luminol reagent [1], and quickly sprayed it evenly on the hood, and in the middle of the hood, two columns and a huge blue-green fluorescence appeared.

This discovery made Zhou Ning more confident, lying on the edge of the windshield from the side of the front of the car, spraying luminol reagent in the gap between the windshield and the hood, and sure enough, there was also a fluorescence reaction here.

On the cover of the wiper, Zhou Ning found two purple-black blood droplets and waved his hand at Zhao Xinli.

"The camera handed me and gave me a swab to take a sample[2]."

Zhao Xinli hurriedly handed over the camera, then found the test tube and swab, approached Zhou Ning to watch him take pictures, and asked with interest.

"What did Forensic Officer Xiao Zhou find?"

"The bloodstains, which I suspect is the blood of the deceased, fell on the wiper cover, and I guess I didn't find it when I cleaned it up, just wiped the blood off the hood.

Although it is impossible to sample here, the two columnar forms are completely consistent with the blood stains on the lower edge of the deceased's right ribs. ”

Zhou Ning spoke quickly, the movements in his hands were faster, the swab was dipped in distilled water, a blood sample was collected, one end was broken and thrown into the test tube, and handed it to Zhao Xinli.

Zhao Xinli didn't talk nonsense, grabbed the bottle and ran, Zhou Ning climbed out of the car, took the fingerprints and palm prints he had just collected, and went straight to the office on the second floor.

Turn on the computer with a big belly display, don't look at this computer is broken, the performance is not bad, and a fingerprint comparison software is also installed in it.

Zhou Ning entered the fingerprints he had just collected into the numbers, and did the same with the fingerprints marked with Chen Feiyu and Wang Fuhao on the table, and then began to click and compare.

Except for a few that are too mutilated to be compared, several fingerprints show that the comparison is successful, and you can directly click to print the comparison results.

Zhou Ning clenched his fists and waved, great, although there are no fingerprints in the Volkswagen CC, Wang Fuhao's fingerprints were found on the doors and gear handles of Nissan, which proves in disguise that Wang Fuhao did not lie, they did change cars.

As for who hit the deceased, the result is self-evident, but how could Wang Fuhao rush to repair the car and help Chen Yufei cover up these evidence?

As Zhou Ning's thoughts popped up, a familiar prompt sound sounded in Zhou Ning's ears.

Drop, congratulations to the binders, the temporary task has been submitted successfully!

Evidence: Fingerprint collection was completed, and bloodstain extraction and comparison were successful;

Driver: Chen Yufei;

Vehicle involved in the accident: Volkswagen 2010CC

Time remaining in the countdown: 33:30

Rewards are being distributed and take ten minutes to load.

Zhou Ning sat down subconsciously, after all, the discomfort of the loading process last time made him palpitate, but this time it was fortunately in his office, and sure enough, the feeling of breaking his head came again, but the degree was not as uncomfortable as the first time.

This feeling lasted for a long time, and Zhou Ning even felt that time seemed to be slowing down, and with the two sounds of Didi, all the discomfort dissipated.

Zhou Ning sat slumped in the chair, gasping for breath, curiously looking through the knowledge learned on the spot by looking at medicine, and nothing else could be compared, he went directly to the end of the rubber trace inspection part, and found the paper given later.

Sure enough, the last paper time is 2019, [Year (Volume) Issue] 2019 (036) 008, Zhou Ning is excited.

Awesome, this is another three years of new knowledge.

Picking up the comparison results, before he could get up, the door of the office was pushed open directly, Xu Dayuan strode in, and seeing the expression on Zhou Ning's face, he asked hopefully.

"What's going on? What evidence has been found? ”

PS:

[1] Luminol: (Luminol) is also known as luminous ammonia. The chemical name is 3-amino-phthalamidehydrazide. At room temperature, it is a pale yellow powder, which is a relatively stable synthetic organic compound.

For blood that cannot be observed with the naked eye at the crime scene, luminol reagent can show a very small amount of blood stains (occult blood reaction), and luminol is a strong weak acid, which has a certain irritating effect on the eyes, skin, and respiratory tract.

Since hemoglobin contains iron, iron catalyzes the breakdown of hydrogen peroxide, turning hydrogen peroxide into water and monooxygen, which reoxidizes luminol to make it shine. Therefore, luminol is widely used in criminal investigation, bioengineering, chemical tracing and other fields.

In forensic science, the luminol reaction can identify blood stains that have been scrubbed and have been used for a long time. Biologically, luminol is used to detect the presence of copper, iron, and cyanide in cells.

[2] Swab: It can be understood as an extended version of a cotton swab with a broken head, and is usually used as a medical examination tool to collect microorganisms, exfoliated cells, or secretions.
