National Forensic Doctor

Of the two routes planned by Liu Jinghui, the second one is a bit difficult.

The distance between the discovery sites No. 1 and No. 2 is more than 80 kilometers. If they ran all along the national highway, three to five cadaver dogs might not be able to clear them all in half a month.

This is still not too far from the national highway. If it spreads out a little further, the investigation will take longer.

Of course, from the perspective of murder investigation, both of Liu Jinghui's plans are biased towards the middle class, including the second one. For murder cases, this cost is also acceptable.

The question is who bears the cost. Ningtai County certainly cannot bear such a large cost. As for Luyang City, this will still require communication.

The matter of communication needs to be handled by Chai Tong on the one hand, and on the other hand, it actually needs to be figured out by the Luyang Municipal Bureau.

Jiang Yuan and others are not too anxious. The case has just been opened, and it actually takes a while for everyone to understand the facts of the case.

However, it was the first plan proposed by Liu Jinghui. Jiang Yuan sent 8 people and formed 4 teams to go on a business trip to Luyang City.

Of course, these eight people cannot conduct a detailed investigation, but they should be able to help define a scope and lay the foundation for the subsequent investigation of the large force.

Otherwise, it would be a waste of manpower for a group of people to run over with a blind eye.

Liu Jinghui also went back to Changyang City to report. The 805 case was also a case registered by the provincial department. There was no supervision, and it was also feared that the Luyang Municipal Bureau would be forced to death.

Jiang Yuan continued to grade the papers and looked at the photos over and over again.

There is no body or scene, so we basically have to rely on files to solve the case.

This is largely why the backlog of cases is difficult to solve. Time is the biggest enemy of traces. Roca's Law, the basis of forensic science, states that "every contact must leave traces." Only time can quietly send traces into nothingness.

Fortunately, the basic information is retained in the photo.

Jiang Yuan watched for two days before turning his attention to No. 2's arm.

Compared to No. 1, who has abundant information, No. 2, who has only one arm, has not yet determined the source of his body. If it can be determined, it will definitely be a big boost to the case.

However, although Jiang Yuan and Luyang City both speculated that No. 2 was probably also a traitor, it was not that easy to confirm his identity.

The third day.

Six people came to Luyang City at once.

Director Chai Tong went out to greet him personally and called several deputy directors to accompany him. Jiang Yuan was also called over, showing off his grandeur. Those who came were Zheng Tianxin, the detachment leader of Luyang City Criminal Police Detachment, political commissar Zhou Yuanqiang, a certain brigade captain, general police officers, and forensic doctor Mei Fang.

Chai Tong and Zheng Tianxin held hands and smiled as if they were reunited after a long separation.

Jiang Yuan watched boredly from behind. It had been several days and the bargaining with Luyang City had not ended. If the relationship was really so good, why would it end?

Mei Fang showed an apologetic smile to Jiang Yuan.

Political commissar Zhou Yuanqiang cheated him, and he had no choice but to apologize to Jiang Yuan first.

At the end of the interactive session, a group of people supported each other and walked into the conference room of Jiang Yuan's backlog class.

Zheng Tianxin has already learned about Zhou Yuanqiang's experience. Even if Zhou Yuanqiang doesn't want to say it, Mei Fang will not endure it and suffer the consequences of being dumb. As a forensic doctor, it is not easy to scold the detachment leader, but it is still very reasonable to tell the truth.

Zheng Tianxin therefore changed his strategy and asked Jiang Yuan modestly. Jiang Yuan also said it again about the identification of the time of death.

Zheng Tianxin seemed to be listening attentively. The level of this meeting was slightly higher, and it was also necessary to decide the next direction. Soon, Jiang Yuan told the information previously described.

Zheng Tianxin nodded, picked up the cup and took a sip of water, ready to speak.

Jiang Yuan continued: "I studied the arm of Corpse No. 2, and there is something special about it." Zheng Tianxin was stunned. He had never heard about the condition of Corpse No. 2 before.

He couldn't help but look at Zhou Yuanqiang, who also shook his head slightly.

All the people present were police officers. Watching their expressions interact, it was like listening to him

They shouted as clearly as they could. Jiang Yuan even said directly: "I only studied No. 2 in the past two days."

Zheng Tianxin said "Oh" and said hurriedly: "Keep talking."

Jiang Yuansui said: "Judging from the arms, No. 2 should weigh more than 120 kilograms. Women with a height of more than 165 centimeters should be slightly fatter based on their fat ratio."

Zheng Tianxin's expression condensed and he turned to look at his own forensic doctor, Mei Fang.

Mei Fang looked calm. If he couldn't do it, he just couldn't do it. He couldn't calculate his height and weight with one arm anyway.

Jiang Yuan had newly acquired LV4 forensic evidence, and after looking at the photo of his arm for a few days, he said clearly: "The fingerprints on No. 2's arm were destroyed, but he should have had manicure done. The specific ingredients are Then we can analyze it and see if we can find a similar nail salon.”

The feasibility of this was very high. Zheng Tianxin couldn't help but sit up straight and asked Mei Fang directly: "Have we checked before?" "We wiped trace evidence, but no results." Mei Fang said.

"You've never compared it to a manicure, right?" Jiang Yuan saw the details under the horse hoof mirror. Mei Fang was stunned and said hurriedly: "No, I didn't consider getting a manicure at that time."

"It's not too late to compare." Zheng Tianxin responded in a deep voice.

After four years of working on the case for more than ten months, I thought I would never find any evidence. Unexpectedly, Jiang Yuan spent a few days looking at it and figured out something new.

Zheng Tianxin couldn't wait.

Jiang Yuandao: "Even if the identity of No. 2 is confirmed, it is impossible to solve the case directly. The murderer should be experienced. It is likely that he has been in isolation."

Zheng Tianxin just said "En". For them, this was a rare new breakthrough, and they must investigate it to the end.

Looking at Jiang Yuan again, Zheng Tianxin found that the previous strategy was still too simple. This one is really ridiculously strong.

It's not that Mei Fang is making random complaints.

Chai Tong was very happy to see it. When he was in Luyang, although he was a political worker, he had not had much contact with the 805 case, but now seeing Zheng Tianxin frustrated, he felt happy.

Zheng Tianxin no longer cared about Chai Tong, and asked Jiang Yuandao more humbly: "Captain Jiang, if you are asked to take command, what will happen next?"

"If you really want me to take command," Jiang Yuan pondered for two seconds and said, "I will ask Xu Taining and Xu to come over and conduct a large-scale investigation."

Xu Taining was the first-level senior police sergeant who was responsible for directing the investigation work during Liu Jinghui's disappearance. He was famous for not scrimping on costs, fighting high and exploiting high, high cost and high output.

Zheng Tianxin had obviously heard of Xu Taining's name, and he trembled: "Is it necessary?"

"Yes." Jiang Yuan replied flatly. Liu Jinghui talks about input-output ratio, Xu Taining never pays attention to this, but Xu Taining's crime detection rate is high.

What Zheng Tianxin needs is obviously to solve the case.
