Chapter 819: Analysis

"Jiang Yuan feels there is a problem with the time of death. Then if we count from the last eyewitness who saw the victim... it's equivalent to discovering the body 8 days later. This time difference is too long."

In the conference room, Ma Jiyang, the captain of the Second Detachment of the Criminal Police Detachment, pinched his fingers to count, his brows furrowed.

This case was originally handed over to the Second Detachment to investigate, and Ma Jiyang himself, as the ceiling of meritorious service in the Criminal Investigation Detachment, had solved many cases, and he had rarely encountered a forensic doctor who significantly modified the victim's time of death.

"It won't be as long as 8 days." Jiang Yuan made a slight correction: "I estimate it's about five or six days, and then the victim's body was discovered."

In one day, although the reason had not been fully determined, Jiang Yuan barely determined the time, increasing the time of death from 3 days to about 6 days.

Ma Jiyang said: "As far as we know, on the evening of the 4th, the last patient left Li Yanmin's clinic. The victim Li Yanmin didn't open the door on the 5th, only notified everyone in the WeChat group that he would rest for a few days and close the door temporarily. After that, no one saw Li Yanmin. In the following days, Li Yanmin chatted with people on WeChat, but never made or received any phone calls."

"Has this situation appeared before? The clinic closed for several days. What should the villagers do if they want to see a doctor?" Liu Jinghui asked.

"There is also a clinic in the town, less than 10 kilometers away from the village." The responsible police officer answered on his behalf, and then said: "Li Yanmin often closes for short periods. He liked to travel abroad for a period of time, and would sneak out to play two or three times a year during the off-season. Occasionally, he would stop business for a day or two. The villagers are used to it."

"He does this job comfortably, much more comfortably than us." Liu Jinghui was quite surprised: "You don't even have to watch the shop when you open a clinic?"

"Listening to the villagers, Li Yanmin was married once before, a flash marriage and flash divorce, and had no children. Later, he didn't look for a partner. The villagers introduced him, but he didn't want it. He is unmarried and has no children, and has a house and a clinic. People must live comfortably." The responsible police officer became more envious as he spoke.

Ma Jiyang coughed twice and comforted: "Don't think so. He lives more comfortably than us, not because he is unmarried and has no children, but because everyone lives more comfortably than us."

The responsible police officer opened his eyes wide and looked at Ma Jiyang, who was known as the ceiling of happy marriage in the criminal investigation team, and said: "Captain Ma, you say so, and my mood is much better."

"Right. Don't be afraid of marriage. Anyway, in our line of work, marriage is already difficult, so there is no need to worry about marriage at all. If someone is willing to marry you, it means she is confused, not our fault." Ma Jiyang became happier as he spoke.

"Captain Ma is worthy of being the ceiling of mental health." Liu Jinghui praised.

Ma Jiyang laughed. Yu Wenshu was also watching and laughing on the side, not stopping the few people from going off-topic when discussing the case.

Ordinary case analysis meetings are not in a very serious state, or rather, a relaxed atmosphere is conducive to the exertion of creativity. Many criminal investigation agencies pay attention to discipline in their daily lives. When it comes to case analysis, the few core decision-makers surround them, and they are still allowed to be informal.

Compared with the criminal police teams below, the Changyang City Criminal Investigation Detachment is itself the top-level criminal case detection agency in Shannan Province. It can be said to be the highest criminal investigation agency on the front line. The members of the team are also elite members with experience and ability. For the management of such units, Yu Wenshu has never emphasized discipline.

After a few short jokes, naturally, some criminal police pulled the topic back and said: "Assuming the time of death is modified to six days ago, that is, closed on the 5th, and died on the 7th or 8th. During these two days, Li Yanmin's WeChat had information sent to others. If he is already dead, the WeChat information is likely sent by the murderer?"

"What about the WeChat chat records? Bring them and take a look." Yu Wenshu beckoned.

Immediately, a police officer handed the printed WeChat chat records to Yu Wenshu. In the current case, using WeChat as evidence has become a common phenomenon. Many financial dealings and proof of relationships are done using WeChat.

Yu Wenshu flipped through the WeChat chat records page by page. He had paid attention to this case before, but he hadn't been meticulous about every piece of evidence.

Liu Jinghui had read the WeChat records before, but only said: "Li Yanmin's mobile phone signal only went offline on the 9th. Whether it was under the control of the murderer during this period is not certain, but it is a line of investigation."

Liu Jinghui was not optimistic about this clue.

Most of the land in the village where the victim is located has been rented out to build factory buildings. These factories have as many as one or two thousand people, and as small as a few or a dozen people. The self-built houses in the village also have many partitioned rentals, and some factories also have dormitories. The environment is complex and the personnel are mixed. To obtain effective clues from such places, ordinary visits are useless. It is basically the level of investigation.

Liu Jinghui was not afraid of investigation. He also possessed the skill of calling Xu Taining, but the summoning time was a bit longer, not to mention that Jiang Yuan was here this time. The problem is that finding a mobile phone is too far from finding the murderer. The mobile phone being in the hands of the murderer is just a guess, not even reasoning. And even if the mobile phone is found, it doesn't necessarily mean the murderer can be found.

On the other hand, as a high-value property, the mobile phone itself has extremely strong liquidity. A very easy-to-understand assumption is that if the murderer abandons the mobile phone on the side of the road, how long can it stay in a place full of floating population?

And according to the current mobile phone circulation mode, if the person who picks up the mobile phone sells it, it might even reach Huaqiangbei in 24 hours. Liu Jinghui does not suggest spending manpower and material resources to investigate for such clues until he is desperate.

"I think we should still make a fuss about the time of death." Liu Jinghui still trusted Jiang Yuan's discovery more. In his heart, he had a degree of trust in various evidence, but he wouldn't say this on a daily basis.

Yu Wenshu also trusted Liu Jinghui and asked: "What ideas does Division Chief Liu have?"

Liu Jinghui said: "First of all, I see that Captain Ma has already started, that is, the time of death has been advanced. Then the previous investigation should also be pushed forward. For example, surveillance video, for example, the content filmed by the vehicle checkpoint before, and the eyewitnesses visited, should all be extended to at least before the 7th."

Ma Jiyang nodded on the side and said: "This aspect is being done."

"The second point is, how did the murderer manage to make such a big difference in the time of death? It shouldn't be an ordinary means, right?" Liu Jinghui looked at Jiang Yuan and asked: "If this problem can be solved, maybe the case will be solved."

In reasoning cases, if there is a situation that is obviously contrary to common sense, then explaining the situation can often explain the whole case. Liu Jinghui's secret line of thinking is this.

"I have been considering this problem all day today. In fact, there are still some methods, but which one it is specifically depends on the inspection results of various aspects." Jiang Yuan said here, specifically explaining: "Toxicology laboratory, physical and chemical laboratory and trace evidence laboratory, and DNA laboratory, I have sent a lot of inspection materials, the team is full, let's see what results come out in the end."

"I will have people urge it and put you in the front." Yu Wenshu said immediately.

The so-called clever woman cannot cook without rice. Without sufficient evidence, Jiang Yuan's technology cannot be brought into play.

The case analysis discussion reached this point, Jiang Yuan quickly reviewed his technical table and said: "I will go to the map investigation, let's see if Division Chief Liu's surveillance can produce something." ===== CHAPTER 820 =====
