Chapter 1230

When Li Guangnian saw Shen Changfeng again, he saw Shen Changfeng lying on the sofa playing with his mobile phone without any image, looking exactly like an old criminal police officer who had been working for more than five years.

How can this image work!

Li Guangnian frowned and coughed lightly: "What's going on?"

"Boss!" Shen Changfeng threw his mobile phone and rushed up.

Li Guangnian hurriedly blocked him with his hand, stared at Shen Changfeng with the eyes of an old criminal police officer for a few seconds, and said seriously: "What happened? Were you scolded?"

"No." Shen Changfeng's excited mood was blocked by the captain's three-dimensional arm, and the two-dimensional world couldn't hold the emotions, which was quite suitable for being a criminal police officer.

"Director Jiang... bullied you?" Li Guangnian's mind flashed some pictures that were not suitable for talking about at this time.

Shen Changfeng recalled what he had seen and heard over the past period of time, sighed: "No, I just followed Director Jiang to adjust the 3D printer, a bit tired."

"3D printer, Director Jiang also plays with this?" Li Guangnian was surprised.

Shen Changfeng: "Boss, is there a possibility that the 3D printer was designed not to print figures?"

"Did you use a 3D printer to print figures?" The post-80s criminal police captain didn't pick up the topic, but just output questions blindly.

"No, we used a 3D printer to print the murder weapon, the possible murder weapon." Shen Changfeng said.

"Can it be printed? Do you know what the murder weapon is?" Li Guangnian finally grasped the point.

Shen Changfeng: "Director Jiang thinks it's an electrician's knife."

Li Guangnian's gaze instantly became Takenori Akagi: "Amazing, he actually really found it? If it's an electrician's knife, it shows that the occupation is related to an electrician, or there should be people in the family in related industries..."

Li Guangnian said and took out his mobile phone.

Shen Changfeng looked at his actions, his tone cold: "Boss, do you know RealityCapture?"

"What?" Li Guangnian looked stunned.

"I asked the same thing at the time, and had the same expression." Shen Changfeng shook his head slightly: "RealityCapture is a 3D reconstruction software used to generate the morphology of the wound and the surrounding tissues, and also needs to generate a smooth surface through the Poisson surface reconstruction algorithm..."

"What?"

"It's like this!" Shen Changfeng nodded in agreement, and then said: "There is also ANSYS, which is a finite element analysis software used to import models and assign material properties. For example, muscle is 0.5 to 1 MPa..."

Li Guangnian understood, patted Shen Changfeng's spine lightly, and said: "You know, many male protagonists in anime, at the very beginning, won't take a few chapters to encounter a BOSS who covers the sky with one hand. The BOSS's palm can shatter a tower that the male protagonist can't destroy even after racking his brains, but it won't take long for the male protagonist to stand tall in front of the BOSS..."

"You said that, Boss." Shen Changfeng was very moved when he heard a similar story for the first time. Later, after knowing that the captain wholesaled such small stories, he became calm.

Li Guangnian clearly wasn't encountering this situation for the first time. He coughed twice and said: "Then I'll tell another kind..."

After finishing, Li Guangnian didn't wait for Shen Changfeng to respond, and said: "Go see Director Jiang. I'll tell the family. This evidence of the electrician's knife is very valuable!"

With clues, it wasn't just Li Guangnian's First Brigade, the entire criminal police detachment of Donghua City was mobilized, led by the detachment captain himself, and began to search for various evidence.

For Donghua City, this rainy night homicide case itself was highly valued. Having passed through the hands of the previous expert, it now fell into Jiang Yuan's hands. Everyone understood that this was basically the last chance for a frontal investigation.

If Jiang Yuan participated and still couldn't solve the case, then later on, it would be impossible to count on inviting any expert to participate in the frontal investigation of this case. It could even be said that inviting other experts to participate in the frontal investigation of this case, the latter wouldn't think it was a trap, which would be good.

Normal criminal investigation experts, as long as they don't owe you a life, are highly unlikely to intervene in this case. Unless some extremely important evidence appears in the future, such as the murder weapon jumping out directly, or the suspect of a certain case reporting or even confessing...

This is like an exam paper. You see the top 10 student in the grade do it, and the result is not passing. Is there any need for you to do it? This is not a free attempt. People who get a failing grade again not only easily get mocked, but also may lose substantial benefits...

Of course, these are things for later. For the Donghua City Criminal Police Detachment, they are in the state of doing the paper now, so naturally, they have to go all out.

The victim's identity is clear. He is a salesperson for a small trading company. He doesn't have many opportunities to come into contact with electrician's knives in his profession. The criminal police team then turned their attention to his life and relatives and friends.

At this time, the manager of the company, Zhang Zhanjun, who had once been listed as a suspect, was placed under a microscope.

"Suspect Zhang Zhanjun, male, 46 years old, undergraduate education, is the boss of the company where the victim Qin Rui worked. Graduated from electrical engineering and automation, and worked as an electrician." Li Guangnian got this news and immediately came to find Jiang Yuan, saying: "He is the last person among Qin Rui's colleagues to see Qin Rui. We have already taken a transcript for him."

Regardless of anything else, now that there is an entry about having worked as an electrician, everyone is facing a formidable enemy.

Jiang Yuan asked: "How was the suspicion cleared?"

"Qin Rui's time of death is uncertain. It's very likely that he died a few days after going missing. Zhang Zhanjun has an alibi. In addition, Qin Rui and Zhang Zhanjun didn't have much interaction, at least according to their colleagues." Li Guangnian paused, took out his notebook and looked at it for two glances, and then said: "We also asked the technical reconnaissance and image reconnaissance to check the mobile phone and surveillance. Qin Rui should have returned to the rental house that day, and then left again."

Li Guangnian stopped for a moment when he said this: "However, if you look at Qin Rui and Zhang Zhanjun together, Qin Rui working overtime that day was not necessary. On the last day, the only people working overtime in the company were the boss Zhang Zhanjun and the salesperson Qin Rui, which feels wrong."

Liu Jinghui also scanned the relevant information at this time and said: "Zhang Zhanjun has opened a company in the capital. His work focus over the past two or three years has been in the capital."

"Bring him over to ask first." Jiang Yuan had no more doubts.

Li Guangnian was startled: "Shouldn't we investigate the periphery first? The suspect shouldn't know that we have investigated him. A boss who opens a company in the capital might be able to contact someone. Is it better to have some evidence before arresting him?"

His case is here, so he had to put forward his opinion.

"The suspect himself is the best evidence." Jiang Yuan said affirmatively: "Bring him over to leave footprints and fingerprints, take DNA, take gait, and run through the surveillance videos around the two cases behind to see if he has appeared in the vicinity."

Liu Jinghui nodded in agreement: "He might be the last eyewitness, and has experience related to electricians. In addition, he has money, and has appeared in Donghua City and the capital successively. The degree of suspicion is already very high. I suggest a surprise inspection of his real estate and company assets!"
