Chapter 539: Means Exhausted

"So you changed the plan?"

Cui Xiaohu and Li Haochen, who had returned from a round, arrived in Qingbai City and received some complaints, so they had to come to ask Jiang Yuan.

Jiang Yuan then told the two of them about Liu Jinghui's series of inferences.

Li Haochen nodded frequently as he listened, and after asking two more questions, couldn't help but be surprised: "I've heard of the name of Liu Jinghui from Shannan, but I didn't expect him to have real stuff. Captain Jiang, help me introduce him later."

Li Haochen looked like a young police officer who had just graduated from the police academy. He was also a character who didn't like to talk much before. After listening to the inference of Liu Jinghui relayed by Jiang Yuan, he became interested.

There was nothing to say. Jiang Yuan turned around and called Liu Jinghui over, and then introduced the few people.

"I've heard of the name of Liu Chu." Liu Jinghui obviously paid attention to Li Haochen. After all, he was a cadre from the ministry. No matter how small, he was a leader, and a fart could make people in the whole province smell the stench.

Li Haochen was modest, and then discussed with Liu Jinghui freely.

He also traveled on business all year round and knew how to communicate with famous detectives from all over the place.

After just a few words, Li Haochen released his famous saying: "If it were me killing these three people, I would have to find a means of transport. Otherwise, even if I go out in the middle of the night, if I meet someone on the road, it's not clear. If I'm not careful, I'll be exposed."

"That's right, so, given the conditions 20 years ago, it would be trains, cars, tricycles, etc."

"It's quite difficult to get on the train. It's such a big person, how to bring it to the train station? Even if it's a freight station, there are quite a few people coming and going. Just get a flatbed truck used for maintenance on the railway?"

"Is it a rail car? It's possible." Liu Jinghui was still in an open state, looked at Li Haochen, and smiled: "If you were to do it, how would you choose?"

Li Haochen really thought seriously for a moment and said: "The flatbed truck is also fixed on the railway. The problem of moving the body to the flatbed truck is about the same as moving the body to the railway, unless you kill someone next to the railway. However, why not just abandon the body on the spot?"

"In the end, you still have to have a means of transport." Liu Jinghui nodded.

"And you have to have appropriate camouflage." Li Haochen added a point: "I couldn't have planned it so meticulously, only to fail at the last moment because of an accident."

"Indeed." Liu Jinghui agreed and nodded, looking at Li Haochen's young face, feeling a bit appreciative, and said: "Li Chu is also quite good at reasoning. And the angle is very special."

"No way." Speaking of this topic, Li Haochen couldn't help but sigh for a long time.

Liu Jinghui asked: "How to say?"

Li Haochen shook his head: "In the current environment, in the Criminal Investigation Bureau, reasoning alone is not enough. I also have to do some fieldwork from time to time, do some undercover work..."

Liu Jinghui's tears were about to flow down as he listened.

This is too difficult!

Jiang Yuan stayed in the laboratory for three days before he managed to extract a part of the pollen from the No. 2 victim's clothing.

Being able to do this step is also a manifestation of his status improvement. Because extracting pollen is a destructive operation, Jiang Yuan's approach was to cut six pieces of fabric from the clothes. Later, if any expert does this case again and wants the complete clothing of the victim, they will be blocked.

However, it's a case from 20 years ago, and considering the future, it doesn't make much sense.

If the murderer was a young man back then, he might still be there now. If he was middle-aged or older, the murderer might have already died. What is the significance of solving the case and finding the so-called truth?

Of course, the main thing is that the strength Jiang Yuan showed is sufficient. For leaders at all levels, the current Jiang Yuan is qualified to decide the direction of the case.

Jiang Yuan also really made something.

In the subsequent small case analysis meeting, Jiang Yuan asked someone to make a PPT and simply said:

"The No. 2 victim is a 27-year-old woman who opened a frozen food store herself. In the market where she was, there was a flower shop, so there was a large amount of commercial flower pollen on the victim's clothing, which made the botanical analysis a bit difficult."

"However, a particularly special point is that I found a series of tree pollen such as fir, metasequoia, dragon cypress, ginkgo, etc., on her clothing..."

"The discovery site of the No. 2 body is in the southern suburbs of Huo City, where there is little planting of such trees, but the botanical garden in the western suburbs has a complete variety. Therefore, it can be basically inferred that the western suburb botanical garden is likely the first scene of No. 2."

Jiang Yuan paused here and added: "Captain Wu Junhao has already led a team to visit."

Liu Jinghui's expression was serious: "Being able to find the first scene should have been a big breakthrough, but if it is a botanical garden, the traces of 20 years ago are unlikely to remain."

"Unless there are murder weapons left behind." Jiang Yuan had no choice. If the scene was in a residential building, in the resident's home, it would really be possible to find blood or DNA. Although the 20-year time is long, those that were not cleaned up back then might not be cleaned up 20 years later.

The botanical garden is different. There are natural decomposers in the botanical garden, from insects to microorganisms to various fungi. No ecological niche can be missing. And in such a place, let alone biological materials, normal clothing can be decomposed cleanly.

"At least it shows that the victim had been to the botanical garden that day." Liu Jinghui said this, pulling the dull atmosphere back.

Jiang Yuan nodded and said: "The victim had dinner with her parents the night before. If she went from the southern suburbs of Huo City to the western suburbs the next day, there should be a commute time of 30 minutes to 1 hour, right? She should have taken the bus."

"Are there any eyewitnesses?" Liu Jinghui looked to the side.

There were police officers from Huo City sitting in the meeting, who were sent to the special task force. At this time, they leaned forward and said: "Someone saw the victim leave the market, but there were no eyewitnesses later. At that time, I didn't know where she went..."

Liu Jinghui suddenly had a little excitement and said: "It was a working day, right? A frozen food store owner couldn't run to the botanical garden to play for no reason. Even 20 years ago, there was no one running to the botanical garden to play."

Li Haochen also said: "The victim is 27 years old, unmarried, no boyfriend... Is she in love? Crime of passion?"

"It is not excluded that there is such a possibility."

"If it is a crime of passion, this victim is the only person related to the murderer."

"How to prove it?"

When saying this, Liu Jinghui and Li Haochen both looked at Jiang Yuan.

Jiang Yuan spread his hands. Even if there was surveillance 20 years ago, the videotapes might have been scrapped. There are not many items as tough as pollen spores. Many things that felt very hard at the time became soft a few years later.

"You can ask the people around you again. Maybe there is a secret boyfriend or something." Li Haochen took evidence from Jiang Yuan again: "Is the victim a virgin? Any signs of pregnancy?"

"No. Not pregnant." Jiang Yuan is well-read in the autopsy report.

"I think it is necessary to conduct a comprehensive inquiry of the victim's relatives, friends, colleagues, and acquaintances." Li Haochen said: "There should be no online dating 20 years ago. If she wants to fall in love, she must have a contact channel."

"There is online dating." Liu Jinghui looked at the young Li Haochen and said: "We were making friends in chat rooms in the nineties."

"Okay." Li Haochen didn't argue, and said again: "The means of transport should also be checked. If the victim died in the botanical garden, the murderer wants to transport her out of the botanical garden and arrive at the railway on time. Cars are inconvenient. Tricycles? Feels better than motorcycles, has concealment, and the price is not expensive."

"Tricycles were indeed very common in the city back then." Liu Jinghui didn't object, but these two lines, it's easy to say, but it's not easy to investigate.

Jiang Yuan had no good means at this time, so he said: "Call Xu Chu over."

Huang Qiangmin looked at Jiang Yuan and said: "You have stood Xu Chu Tai-ning up twice. He may not be willing to come."

"You just tell him that I am at a loss, and this case cannot be solved in the short term." Jiang Yuan smiled, which could be considered the truth.

The corner of Huang Qiangmin's mouth couldn't help but hang a 66.6-degree smile: "For Xu Chu, it might be tempting." ===== CHAPTER 540 =====
