Seeing Han Rui and Wen Jie running over quickly, Xu Zheng hurriedly waved his hand to signal that he was fine, Han Rui ran to him and wanted to complain that he ran out like crazy just now, but when he saw Xu Zheng lying on the road on such a hot day, the ground was full of sewage, and he felt distressed again, "Xiaozheng, what are you doing here?" Hurry up, we can bake eggs on the ground of Changming. ”

"Sister Xiaorui, I'm fine, didn't I say a different angle, I now follow the angle of the coin and find that the coin should be flying parallel to the ground, and to ensure that the arc of the landed coin is not high, it has to fall on the road, and this coin launcher should not be too high above the curb." Xu Zheng seemed to explain to Han Rui, and it seemed to be his own analysis.

As his words fell, he and Wen Jie stared at the fixed metal trash can diagonally across the road at the same time.

Xu Zheng faintly felt that he felt right this time, and walked quickly to the trash can and squatted down, the street lights were too dim, and he couldn't see anything under the trash can, Han Rui saw it, and immediately turned on the flashlight on his mobile phone and squatted down to help him shine it.

"Haha... Look, you see, there's a black thing fixed under the trash can, and this long, black cylindrical thing is clearly facing the place where I was just lying. ”

Wen Jie was also very excited, if it was determined that it was the transmitter that catapulted the coin, then this accidental car accident was no longer an accident, but a man-made one. If someone can really use this chain of coincidences to commit this case, then is this the first time he has committed a crime?

The more she thought about it, the more cold she felt, obviously the night in Changming City was still very hot!

"Xiaozheng, how inconvenient it is for you to lie on the ground, can't you just take it out and look at it again?" Han Rui felt sorry for Xu Zheng and lay on the ground again.

Wen Jie shook her head to sober herself up, "Xiaorui, this is evidence, what if there are suspect fingerprints on it, so I still have to come to the physical evidence department of the bureau to collect evidence." ”

Han Rui's face flushed, and she was really concerned, "Yes, Wen Jie, you are right, Xiaozheng, you hurry up, can't you wait for your colleagues to collect evidence and then observe?" ”

Xu Zheng laughed, stood up hurriedly, and excitedly wanted to step forward to hug Han Rui, but when he thought that she would retreat again and again, Xu Zheng was a little surprised at first, but when he looked down at himself, his white pajamas were full of dirt, especially his back, which was wet with sewage.

"This, ha... I didn't even pay attention, by the way, Wen Jie, you call the director to report, I didn't bring my mobile phone, let him notify... Forget it, you can tell us about our findings, and he will arrange it.

When you're done, you can tell our team members, you don't have to come over first, just arrange it after listening. ”

Wen Jie nodded, glanced at Xu Zheng deeply, and saw that his eyes were clear, and she didn't feel how generous he was at all what he said just now.

She now admires Xu Zheng more and more for this young man, he is bold and careful, his brain is turning, and the most important thing is not to be greedy for credit, if this matter is left on others, he will definitely grasp the credit of the first to find evidence and ask the leader for a task.

Within 15 minutes, Wang Nianpan drove over, and just stopped Yan Zizhong and a few people from the criminal police team came over, including two from the Physical Evidence Department, who did not act immediately after they arrived, but pulled Xu Zheng and asked him how he found out.

How to find out, of course, is a different angle.

Asked how he thought of changing this angle, Xu Zhenggang wanted to open his mouth to answer, but saw that Han Rui was still here, "Oh, I just thought that I just suspected that there was this catapult before, didn't I find it all the time, no, I did a coin parabolic experiment at home, and I thought it was possible, so I came to the scene to try it and found this thing." ”

They are all people on the criminal investigation line for many years, they know that Xu Zheng's statement is a pretext, this road is a two-lane road, and the entire parabola distance of the coin is about seven or eight meters, and it takes a lot of experiments to adjust this transmitter if the coin is ready to be thrown into the position where the old man often picks up coins, which can be seen that this is not something that an ordinary person can do.

After a while, Deputy Director Xu Xiuchuan rushed over, "Quick, tell me quickly, is there that coin catapult down here?" ”

Two colleagues from the Physical Evidence Division were lying on the ground looking at each other, and when they heard this, they stood up, "Report to the Director, we did find a long barrel, but it's not a transmitter that hasn't been finalized yet. ”

Xu Xiuchuan hurriedly asked them to start, "Be careful, see if this highly intelligent person has left fingerprints." Although he said this, he knew in his heart that there was almost no possibility of fingerprints being left.

He saw Yan Zizhong and Wang Nianpan's faces solemn, obviously knowing what they were worried about, the more high-IQ cases the more difficult it is to solve, and the more serious it is the high-IQ crimes, he is not one or two cases, according to the inference of previous crimes, this may be a serial case.

"Look at you like this, what's wrong with high-IQ crimes, it's not that we haven't caught it, it's still the same sentence, Skynet is restored and negligent, as long as the case is done, there will be traces." As he spoke, he glanced at Yan Zizhong again, "Self-respect, don't you also have two colleagues in your criminal police team who are tracking this case, what are the results?" ”

Yan Zizhong glanced at Xu Zheng and shook his head, Xu Zheng was not surprised in his heart, sure enough, the criminal police team did not give up the case, but moved behind the scenes.

At this time, Yan Zizhong's heart moved, and the director asked, is that it, "Director, you won't let Xu Zheng and them continue to investigate this case, right?" If you want me to say, Xu Zheng was temporarily transferred to the criminal police team to specialize in this case, what do you think, director? ”

Wang Nianpan pursed his lips and thought in his heart: "What you think is so beautiful!" ”

Sure enough, Xu Xiuchuan waved his hand, "How can there be a truth about crossing the river and demolishing the bridge, Xu Zheng and they can find out this credit, so let them continue to investigate this case, and it will not conflict with your criminal police team." ”

He walked up to Xu Zheng, glanced at Han Rui who was avoiding suspicion in the car, and waved to her, "I heard that you and Xiaorui are living together, okay, you are also 23 years old, I see, I will do it this year!" ”

Xu Zheng glanced at him in his heart and staggered the topic, "Uncle Xu, I didn't lose your face this time, did I?" ”

Xu Xiuchuan laughed, seeing that Xu Zheng was dirty, he knew that he must have fallen on the ground just now without asking, and patted Xu Zheng's shoulder, "You give your uncle a big face, I will call the Wan detachment in a while, so that he dares to look down on you!" ”

At this time, the colleagues of the Physical Evidence Section unloaded the coin catapult, "Director, Team Yan, the preliminary identification of this thing is a coin catapult, but no fingerprints have been collected on it and under the trash can, and three or four fingerprints have been collected on the trash can..."

Yan Zizhong interrupted them with a wave of his hand, the fingerprints on the trash can must not be the murderer's, "Since there is a catapult here, then there must be a murderer's camera in this piece, you check it carefully, and then call the team, send additional manpower, and look for it overnight." Also, you inform Captain Guo to check the breakfast shop owner and the part-time worker overnight, and then ask if their cameras have been copied or seen..."

Xu Xiuchuan nodded when he saw Yan Zizhong's arrangement, "Xiaozheng, you and Xiaorui hurry back to rest, and when there are results tomorrow, the criminal police team will share the results with you." ”

Yan Zizhong didn't wait for the director to order, "Yes, yes, Xiaozheng, hurry back, your girlfriend still has to go to work tomorrow, don't worry, there will be results tomorrow to share with you." ”

Wang Dianpan also waved at him, and at the same time asked Wen Jie to hurry back.

I have to say that the criminal police team is indeed much more powerful than Xu Zheng's team, and the next morning, a document was transmitted, which showed that the deceased was in his sophomore year at Normal University, and because of a misunderstanding, a junior male student of Changming University dropped out.

Xu Zheng only got the general news, and no matter how detailed it was, he had to check it himself, and he understood at a glance that this was a test of Yan Zizun's examination of his touch.
