National Forensic Doctor

The front row of the auditorium today is full of people because it is convenient to pass notes in the front row.

Wang Zhihao and Li Zeming couldn't find a place to hide, so they could only stand on the podium with Jiang Yuan, looking up at the hundreds of people in the auditorium, feeling a little uncomfortable.

There are more people coming today, and you can see with the naked eye that they are all young and middle-aged criminal police. Each of them has a sharp look in their eyes, and it is unclear whether they are thinking about attending the class or preparing to become famous.

Jiang Yuan nodded to Wang Chuanxing beside him and said, "Tell me about the latest developments."

"Yes!" Wang Chuanxing stood up and said, "The suspect, Li Zongwei, is from Wei City, 29 years old. It has been confirmed that he is involved in 4 rape cases. According to the drugs found in the suspect's home, the suspect mainly used GHB, commonly known as rape drug..."

Wang Zhihao and Li Zeming were confused. Should they discuss the suspect directly? Does this require Jiang Yuan's participation?

Wang Chuanxing finished his report and sat down. Wei Shiyan next to him stood up naturally. He had arrived last night.

Lack of sleep made Wei Shishu's eyes a little red, but his expression was quite excited.

After all, it was an independent investigation, and even if the suspect was identified, it was very rare for a junior detective like Wei Shishu to do this. Moreover, his task was to connect the cases in series, which was an expansion of the case. Even if the suspect was identified, it was still an extremely valuable job.

Wei Shiyan picked up the notebook in his hand, glanced at it subconsciously, and said: "We first checked the cases in various places based on the reported information, and then combined Li Zongwei's location and time. At present, a total of 4 cases have been found.

However, considering that some people may not have reported the crime, or are unsure of their status, I made a list and planned to visit a few more cities next time."

"Okay, I'll leave it to you from now on." Jiang Yuan didn't want to hear the follow-up and didn't give the Brahmin any face.

Wei Shiyan chuckled twice and remained calm.

"In the forensic botany department, we compared the suspect's clothing." Pang Jiedong went on stage and Jiang Yuan gave him a little more time.

As for training activities, the criminal police are not new to rape drugs, and forensic botany still needs to be trained. Especially for ordinary police officers from other cities, even if they attend similar training courses, they may not be very serious. People who conduct training should know this.

Pang Jidong talked a little and Jiang Yuan added a few words to his story, which was like another round of teaching on forensic botany.

Li Zeming and Wang Zhihao, who were also standing on the podium, listened in a daze, not quite understanding, but inexplicably feeling that it was sharp. To them, forensic botany was something they had only heard of before. Who would have thought that Jiang Yuan had already started such a large-scale training.

After Pang Jidong finished speaking, several people reported the situation. Jiang Yuan stood up again and said, "The rape case ends here. We will continue to work on the subsequent series and parallel investigations. We will open a new case."

Jiang Yuan said it lightly, and turned to look at Li Zeming and Wang Zhihao with ease, and said, "Let's talk about the cattle farm case?"

"Oh, okay." Wang Zhihao breathed a sigh of relief and began to introduce the situation of Mujian Cattle Farm.

As he was introducing things, Li Zeming realized something. He took two steps back, found Mu Zhiyang, and whispered, "Are we investigating the case on site?"

"Yes. Everyone is curious about this when they first arrive." Mu Zhiyang answered all of Li Zeming's questions at once.

The people on the stage were talking, and the people below were also discussing in low voices.

Wang Zhihao quickly introduced the case, nodded, and stood aside.

"Isn't the crime committed by someone you know?" someone shouted out directly.

"We only investigated the interpersonal relationships of the owner of the cattle farm. Other people in the farm are under investigation." Wang Zhihao replied.

The question and answer were basically similar to what Jiang Yuan asked at the beginning.

"The probability of the crime being committed by an acquaintance is still very high." Someone looked up and said.

"Indeed."

"What does the trace test say?"

Speaking of trace inspection, Li Zeming stood up and said, "The location of the Mujian cattle farm is relatively remote, with an independent access road, which is paved with asphalt and is about 100 meters long. There is an independent courtyard, which is not large in area. The cattle farm has two large cattle sheds, which are basically closed spaces. After investigating the front and back doors of the cattle farm, no traces of prying the doors were found, and no traces of unlocking the doors with a key made later were found."

The original key and the newly-matched key can be distinguished by the trace inspection, mainly because of the different lubrication. In particular, the newly-matched key will often cause scratches on the lock.

"There are no signs of climbing on the ranch wall, and no signs of forced opening of the windows. It can basically be considered a natural entry." Li Zeming said with certainty. Although he did not conduct on-site inspections, the people who conducted on-site inspections were his subordinates, and the relevant photos and videos were also appropriate.

"If he entered naturally, then it's most likely that the perpetrator was an acquaintance." We are all no rookies anymore. Looking at this case, our "criminal sense" is first inclined to believe that the perpetrator was an acquaintance.

As for completing the natural entry without leaving any trace, there are certainly ways to do it, but thieves are unlikely to do it.

The most common way is to break in when the door is not locked, which is not in compliance with the management system of the cattle farm. Secondly, they can also enter with a car, secretly stay in the cattle farm, and then wait until night to steal. Although this mode cannot be ruled out, the difficulty and requirements are obviously on a higher level.

As for the current situation at the cattle farm, any discerning person can see that there is no need to go through so much trouble.

Even thieves choose the cost-effective strategy. Who would want to spend the night if they can just steal something?

"As for the interpersonal relationships of 25 people, with so many of us, it will be quick to check." Someone who was considerate took the initiative to bring it up at this time.

Jiang Yuan had flipped through the case file on the way, and just nodded, saying, "For this case, there is no need to consider several routes—"

"Aren't you going to consider the situation where the crime was committed by someone you know?" Li Zeming was a little surprised.

"It's something you need to consider—" Jiang Yuan didn't finish his words.

"It would be a good idea to look at other options." The considerate detectives spoke up one after another.

There is one special thing about criminal cases. Although statistically, they follow the rules of probability, in individual cases, strange things emerge one after another and accidents are common.

It can even be said that it is precisely because some people are weird and unexpected that they commit these crimes.

At this time, Liu Jinghui said beside him: "How can a cattle farm have famous paintings worth tens of millions, including those by Zhang Daqian?"

Li Zeming said hurriedly: "Because the cattle farm owner himself is an art student——

"Why put it in the cattle farm?" Liu Jinghui corrected the question and said, "Doesn't he have a home? Zhang Daqian's words are also very valuable to people of this level.

There was a sound of people in the audience gasping for air. Purely logical thinking can sometimes easily calm people down.
