Chapter 566: Use all possible means
"Just change the plan?"
Cui Xiaohu and Li Haochen, who had returned from a lap, received some complaining feedback when they arrived in Qingbai City, and had to come and ask Jiang Yuan.
Jiang Yuan then told the two of them a series of Liu Jinghui's reasoning.
Li Haochen nodded frequently after hearing this, asked a few more questions, and couldn't help but said in surprise: "I've heard of Shannan Liu Jinghui's name, but I didn't expect it to be real. Captain Jiang will introduce it to me later."
Li Haochen looked like a young policeman who had just graduated from the police academy. He had not been very talkative before. He became interested after hearing Liu Jinghui's reasoning relayed by Jiang Yuan.
There was nothing to say. Jiang Yuan turned around and called Liu Jinghui over, and introduced a few more people.
"I've heard of Li Haochen's reputation." Liu Jinghui had obviously paid attention to Li Haochen. He was a cadre from the ministry. He was a leader no matter how young he was. His farts could make the entire province smell a foul stench.
Li Haochen gave a few words of humility, and then started discussing with Liu Jinghui freely.
He also travels on business trips all year round and knows how to communicate with famous detectives from all over the world.
In just a few sentences, Li Haochen released his famous saying: "If I come to kill these three people, I must find a means of transportation. Otherwise, even if I go out early in the morning and meet someone on the road, I will say no." It’s clear. If not, it might be broken.”
"That's right. So, based on the conditions 20 years ago, it would be like trains, cars, and tricycles."
"It's quite difficult to get on the train. How can you take someone so big to the train station? Even if it's a freight station, there are a lot of people coming and going. How can I build a flat car like the one used on the railway for maintenance? "
"Rail car? It's also possible." Liu Jinghui is still open-minded. He 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 body on the flatbed car will have the same problems as moving the body on the railway. Unless you kill people right next to the railway, but , then why not abandon the body on the spot."
"After all, we still need transportation." Liu Jinghui nodded.
"You have to have a proper disguise." Li Haochen added, "I couldn't have planned it so carefully, only to have it fall short due to an accident."
"Indeed." Liu Jinghui nodded in agreement. Looking at Li Haochen's young face, he felt some admiration and said, "Li Chu is also good at reasoning. And the angle is very special."
"There's no way." Li Haochen couldn't help but sigh when he mentioned this topic.
Liu Jinghui asked: "How?"
Li Haochen shook his head: "In the current environment, in the Criminal Investigation Bureau, reasoning alone is no longer enough, so I have to go out in the field from time to time to work as an undercover agent..."
Liu Jinghui almost shed tears when he heard this.
This is too difficult!
…
Jiang Yuan stayed in the laboratory for three days before he was able to remove part of the pollen from the clothes of victim No. 2.
Being able to do this step is also a reflection of his status improvement. Because extracting pollen is a destructive operation, Jiang Yuan's method was to cut six pieces of fabric from the clothes. After that, if any expert did this again and wanted to complete the victim's clothes, they would be hindered. .
However, it was eucalyptus 20 years ago, and now that I think about it, it doesn’t mean much anymore.
If the murderer back then was a young man, he might still be there now. If he was a middle-aged man, the murderer might be dead. How meaningful is it to solve the case and find the so-called truth?
Of course, the most important thing is that Jiang Yuan has shown sufficient strength. For leaders at all levels, Jiang Yuan is now qualified to decide the direction of the incident.
Jiang Yuan did make something.
At the next small situation 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 shop. There is a flower shop in the market where she is located. Therefore, there is a large amount of pollen from commercial flowers on the victim's clothes. This makes Botanical analysis is a little more difficult.”
"But what's special is that I found pollen from a series of trees such as fir, metasequoia, cypress, and ginkgo on her clothes..."
"The place where corpse No. 2 was found was the southern suburbs of Huo City. There are very few such trees planted there, but the botanical garden in the western suburbs has a full range of varieties. Therefore, it can be basically inferred that the western suburbs botanical garden is likely to be the first scene of No. 2."
Jiang Yuan paused for a moment before saying, "Wu Junhao's team has already led a team to look for it."
Liu Jinghui's expression was serious: "It should have been a big breakthrough to find the first site, but if it is the botanical garden, it is unlikely that the traces of 20 years ago will be left."
"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 stains or DNA. Although 20 years is a long time, if it was not cleaned up then, it may not be cleaned up in 20 years.
The botanical garden is different. There are natural decomposers in botanical gardens, from insects to microorganisms to various fungi, no ecological niche is lacking. And in a place like this, normal clothing can be decomposed cleanly, let alone biological testing materials.
"At least it means that the victim went to the Botanical Garden that day." Liu Jinghui said this, bringing 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 policemen from Huo City who were sent to the special team. At this time, they leaned over 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. People."
Li Haochen also said: "The victim is 27 years old, unmarried, and has 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 as strong as pollen spores. Many things that feel 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. It would be inconvenient to take a car." , a tricycle? It feels better than a motorcycle, it’s 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."
