Chapter 566
"Just change the plan?"

Cui Xiaohu and Li Haochen, who had run around and returned, received some complaint-like feedback when they arrived in Qingbai City, and had to come to ask Jiang Yuan.

Jiang Yuan then told the two of Liu Jinghui's series of reasoning.

Li Haochen nodded frequently when he heard it, and asked a few more words, and couldn't help but said in surprise: "I've heard of the name of Shannan Liu Jinghui, but I didn't expect there to be a real thing. Team Jiang will introduce it to me later."

Li Haochen looked like a young policeman who had just graduated from the police academy, and he was not very talkative before. After listening to Liu Jinghui's reasoning relayed by Jiang Yuan, he became interested.

There is nothing to say, Jiang Yuan turned around and called Liu Jinghui to come over, and then introduced a few people.

"I've heard about Li Haochen's reputation." Liu Jinghui obviously paid attention to Li Haochen. The cadres from the ministries and committees are leaders no matter how young they are. A fart can make people in the whole province smell bad.

Li Haochen gave in a few words, and then discussed with Liu Jinghui freely.

He is also on business trips all year round, and knows how to communicate with famous detectives from all over the place.

In just a few words, Li Haochen released his own famous saying: "If I came to kill these three people, I must find a means of transportation, otherwise, even if I go out in the early morning and meet someone on the road, I can't say no." It’s clear. If it doesn’t work out, it will be smashed.”

"That's right, so, based on the conditions of 20 years ago, it's like trains, cars, and tricycles."

"It's still quite difficult to get on the train. How can you take it to the train station for such a big person? Even if it's a freight station, there are many people coming and going. Get yourself a flatbed car for maintenance on the railway? "

"A rail car? It's also possible." Liu Jinghui is still open-minded, looked at Li Haochen, and said with a smile: "I asked you to do it, how do you choose?"

Li Haochen really thought about it for a moment, and said: "The flatbed car is also fixed on the railway. Moving the corpse to the flatbed car is the same as moving the corpse to the railway. The problems you encounter are similar, unless you kill people next to the railway. But , then why not just dump the corpse on the spot.”

"Speaking of which, we still need transportation." Liu Jinghui nodded.

"There must be a proper disguise." Li Haochen added, "It is impossible for me to plan so meticulously, but the result fell short because of an accident."

"Indeed." Liu Jinghui nodded in agreement, looked at Li Haochen's young face, unconsciously admiring him, and said, "Li Chu is also quite good at reasoning. And the angle is very special."

"I can't help it." Speaking of this topic, Li Haochen couldn't help but let out a long sigh.

Liu Jinghui asked: "How do you say it?"

Li Haochen shook his head: "As far as the current environment is concerned, in the Criminal Investigation Bureau, reasoning alone is no longer enough, so I have to go out to work from time to time, to be an undercover agent or something..."

Liu Jinghui was about to shed tears when he heard that.

It's too hard!
……

Jiang Yuan stayed in the laboratory for three days before he picked part of the pollen from the clothes of the second victim.

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

However, the case of 20 years ago, after thinking about it, it doesn't make much sense.

If the murderer was a young man, he might still be there now. If the murderer was a middle-aged man, the murderer might already be dead. What's the point of solving the case and finding the so-called truth?
Of course, the most important thing is that Jiang Yuan's strength is sufficient. For leaders at all levels, Jiang Yuan is now qualified to decide the direction of the case.

Jiang Yuan did make something.

In the following small case analysis meeting, Jiang Yuan had someone make a PPT, and simply said:
"Victim No. 2 is a 27-year-old woman who opened a frozen product store by herself. There is a flower shop in the market where the victim is located. Therefore, there are a lot of commercial flower pollen on the victim's clothes, which makes the Botanical analysis is a little more difficult."

"However, something special is that I found pollen from a series of trees such as fir, metasequoia, cypress, and ginkgo on her clothes..."

"The No. [-] body was found in the southern suburbs of Huo City. There are few such trees planted there, but the botanical gardens in the western suburbs are full of varieties. Therefore, it can be basically speculated that the botanical gardens in the western suburbs are probably the first scene of No. [-]."

Jiang Yuan paused at this point, and then said: "Wu Junhao and his team have already led a team to search."

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

"Unless there is something like a murder weapon left behind." Jiang Yuan had no choice.If the scene is in a residential building or a resident's home, it is really possible to find blood or DNA. Although 20 years is a long time, if it was not cleaned up that year, it may not be cleaned up in 20 years.

The botanical garden is different.There are natural decomposers in the botanical garden, from insects to microorganisms to various fungi, any ecological niche cannot be missing.And in this kind of place, not to mention biological test materials, normal clothes can be decomposed cleanly.

"At least it means that the victim went to the botanical garden that day." Liu Jinghui said this, bringing back the dull atmosphere again.

Jiang Yuan nodded and said: "The victim had dinner with her parents the night before, and if she traveled from the southern suburbs of Huo City to the western suburbs the next day, it should take 30 minutes to an hour to commute. She should have taken the bus. "

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

Among the people present were the police from Huoshi, who were sent to the special case team. At this time, they leaned forward and said, "When the victim left the market, someone saw it, but there were no witnesses behind, and I didn't know it at the time." Where did she go..."

Liu Jinghui suddenly got a little excited, and said: "It's a working day, the owner of a frozen goods store, it's impossible to go to the botanical garden for no reason. Even 20 years ago, no one went to the botanical garden to play." people."

Li Haochen also said: "The victim is 27 years old, unmarried, has no boyfriend... Is he in a relationship? Love killing?"

"That possibility is not ruled out."

"If it was a love killing, the victim is the only one who has a relationship with the murderer."

"how to prove?"

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

Jiang Yuan spread his hands. Even if there is surveillance in 20 years, the video tapes may be discarded. There are not many objects that are as strong as pollen spores. Many things that felt hard at the time will soften after a few years.

"You can ask the people around you again. Maybe there is a secret boyfriend or something." Li Haochen asked Jiang Yuan again for evidence: "Is the victim a virgin? Is there any sign of pregnancy?"

"No. Not pregnant." Jiang Yuan was familiar with the autopsy report.

"I think it is necessary to conduct a comprehensive inquiry of relatives, friends, colleagues and acquaintances around the victim." Li Haochen said: "20 years ago, there should be no online dating bar. 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 have been talking about friends in the chat room for more than [-] years."

"Okay." Li Haochen didn't argue, and said again: "The means of transportation should also be investigated. If the victim died in the botanical garden, the murderer would transport her out of the botanical garden and arrive at the railway on time. Cars would be inconvenient , Tricycle? It feels better than a motorcycle, it is concealed, and the price is not expensive."

"In the cities back then, tricycles were indeed very common." Liu Jinghui did not object, but these two lines are easy to say, but not easy to investigate.

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

Huang Qiangmin glanced at Jiang Yuan, and said, "You have released Xu Taining's pigeons twice, so he may not be willing to come."

"Just tell him that I'm at a loss and that this case won't be solved in a short time." Jiang Yuan smiled, which was the truth.

Huang Qiangmin's mouth could not help but hang a 66.6-degree smile: "For Xu Chu, it may be tempting."
