Chapter 566: All Means Used

"Just change the plan?"

After running around and returning, Cui Xiaohu and Li Haochen received some complaining feedback when they arrived in Qingbai City, so they had to come to ask Jiang Yuan.

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

Li Haochen nodded frequently, and after asking a few more questions, he couldn't help but say in surprise: "I've heard of the name of Shannan Liu Jinghui, but I didn't expect that there is a real thing. Captain Jiang will introduce me to him later."

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

There was nothing to say about this. Jiang Yuan turned around and called Liu Jinghui over, and introduced them to several people.

"I've heard of Li Haochen's reputation." Liu Jinghui obviously paid attention to Li Haochen. Cadres from ministries and commissions are leaders no matter how young they are, and their farts can make people in the whole province smell a faint stench.

Li Haochen said a few humble words, and then discussed with Liu Jinghui freely.

He also travels abroad for business all year round and knows how to communicate with famous detectives from all over the world.

In just a few words, Li Haochen said his famous saying: "If I were to kill these three people, I would have to find a means of transportation. Otherwise, even if I went out in the early morning and met someone on the road, I would not be able to explain it clearly. If I am not careful, I might get hit."

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

"It's still difficult to get on the train. How can such a big person be taken to the train station? Even if it is a freight station, there are many people coming and going. Can I get a flatbed truck for maintenance on the railway?"

"Railway car? It's possible." Liu Jinghui is still in an open mind. He looked at Li Haochen and smiled, "What do you choose if I ask you to do it?"

Li Haochen really thought about it seriously for a moment and said, "The flatbed truck is also fixed on the railway. The problems encountered when moving the body to the flatbed truck and moving the body to the railway are similar, unless the person is killed next to the railway. But why not abandon the body on the spot?"

"After all, there must be a means of transportation." Liu Jinghui nodded.

"You also need to have a proper disguise." Li Haochen added, "I can't have planned so carefully, and then failed because of an accident."

"Indeed." Liu Jinghui nodded in agreement, looking at Li Haochen's young face, he couldn't help but admire him, and said: "Director Li is also good at reasoning. And the angle is very special."

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

Liu Jinghui asked: "What do you mean?"

Li Haochen shook his head: "In the current environment, in the Criminal Investigation Bureau, reasoning alone is no longer enough, and I have to go out from time to time, do some undercover work..."

Liu Jinghui's tears were about to flow down.

This is too difficult!

...

Jiang Yuan stayed in the laboratory for three days before he was able to pick out some of the pollen on the clothes of the second victim.

He was able to do this step, which also reflected his improved status. Because extracting pollen is a destructive operation, Jiang Yuan cut six pieces of cloth from the clothes. After that, if any expert does this case again and wants to get the victim's clothes intact, he will be blocked.

However, the case was 20 years ago, and it is not meaningful to consider it later.

If the murderer was a young man, he might still be alive now. If he was middle-aged or older, the murderer might have died. How much meaning would it have if the case was solved and the so-called truth was found?

Of course, the most important thing is that Jiang Yuan has shown enough strength. For leaders at all levels, Jiang Yuan is now qualified to decide the direction of the case.

Jiang Yuan did make something.

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

"Victim No. 2 is a 27-year-old woman who opened a frozen food store. There is a flower store in the market where she is located. Therefore, there are a lot of commercial flower pollen on the victim's clothes, which makes botanical analysis a little difficult."

"But, what's more special is that I found pollen from a series of trees such as fir, metasequoia, cypress, ginkgo, etc. on her clothes..."

"The place where the body of No. 2 was found is the southern suburbs of Huo City. There are very few such trees planted locally, but the botanical garden in the western suburbs has a full range of varieties, so it can be basically inferred that the botanical garden in the western suburbs is likely to be the first scene of No. 2."

Jiang Yuan paused here and said, "Team Wu Junhao has led a team to search there."

Liu Jinghui's expression was serious: "It should be a big breakthrough to find the first scene, but if it is a botanical garden, it is unlikely that traces from 20 years ago will be left."

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

Botanical gardens are different. There are natural decomposers in botanical gardens, from insects to microorganisms to various fungi, no ecological niche is lacking. In such a place, let alone biological samples, normal clothes can be decomposed cleanly.

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

Jiang Yuan nodded and said: "The victim had dinner with her parents the first night. It would have taken 30 minutes to an hour to commute from the southern suburbs of Huo City to the western suburbs the next day. She should have taken the bus. "

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

Present here were the police from Huo City who were sent to the special team. At this time, they leaned forward and said: "When the victim left the market, someone saw him, but there were no witnesses behind him, and there were no witnesses at that time. Know where she went..."

Liu Jinghui suddenly became a little excited and said: "It must be a working day. It is impossible for a frozen food store owner to go to the botanical garden for no reason. Even 20 years ago, no one went to the botanical garden to play. ”

Li Haochen also said: "The victim was 27 years old, unmarried, and had no boyfriend... Was he in love? Killed for love?"

"This possibility cannot be ruled out."

"If it was a murder of love, the victim would be the only person related to the murderer."

"how to prove?"

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

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

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

"No. Not pregnant." Jiang Yuan had read the autopsy report carefully.

"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, there must be a way to contact her."

"There is online dating." Liu Jinghui looked at the young Li Haochen and said, "We have been friends in the chat room since 1990."

"Okay." Li Haochen said without arguing, "The means of transportation should also be investigated. If the victim died in the botanical garden, the murderer would have to transport her out of the botanical garden and arrive at the railway on time. The car would be inconvenient. , a tricycle? It feels better than a motorcycle, it’s more concealable, and it’s not expensive.”

"Tricycles were indeed very common in cities back then." Liu Jinghui didn't object. It's just that these two lines are easy to talk about but not easy to investigate.

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

Huang Qiangmin glanced at Jiang Yuan and said, "You let Xu Taining go twice, he may not be willing to come."

"Just tell him that we are at our wits' end and this trap won't be broken in the short term." Jiang Yuan smiled, which was considered the truth.

Huang Qiangmin couldn't help but have a 6-degree smile on his lips: "For Xu Chu, it may be tempting."
