Before Gu Chen entered the living room, he actually found these white papers, but there was no writing on them.
But now I think about it, Liu Geng's mother has severe visual impairment, which means she can't write at all.
Under these circumstances, doesn't it seem strange that she left so much blank paper in the living room?
An old lady was poisoned and died on the sofa, but no source of the poison could be found at the scene. This abnormal situation is really hard to believe.
With the urging of Officer Wang and Lu Weiwei on one side, and the greetings from Liu Geng on the other, Gu Chen looked at the unusual white paper in his hand, folded it, and put it into his pocket.
At this point it's time to eat.
Officer Wang drove Gu Chen and Lu Weiwei to a nearby small noodle shop.
Not many people came to eat noodles at this time, or it was already past lunch time.
But pasta has an advantage that ordinary food does not have, that is, it can be made in various combinations and very quickly.
Usually the hot water in small shops is insulated and can be boiled by heating it on the stove.
The handmade noodles are packed in a fresh-keeping bag and can be put into the pot directly.
As for the combination of seasonings, there are no less than twenty kinds in the shop. Just pick up the handmade noodles and mix and match the selected dishes freely...
"Hiss!" Lu Weiwei sucked it into her mouth and exclaimed: "Old Wang, I know a secret."
"What's the secret?" Officer Wang was still jealous.
Lu Weiwei raised her head and said, "That means when you are extremely hungry, no matter what food you eat, it tastes particularly delicious."
Then Lu Weiwei pointed at the bowl of noodles and said, "Look, this bowl of noodles is long and wide. I usually don't like it at all, but today it tastes really good."
"So...this is your secret?"
Officer Wang thought there was some great miracle, and raised his head to wait for her for a long time, but it turned out to be this. He couldn't help but shook his head and sighed: "Okay, next time we treat guests, we will postpone it for an hour or two. When you are so hungry, let's go and eat some pancakes."
You can be moved to tears."
"Old Wang, you have changed." Lu Weiwei stared at him with contempt, then turned to ask Gu Chen: "Junior Brother Gu, do you think Old Wang has changed?"
Gu Chen nodded while looking at the white paper.
Nodding was a conditioned reflex, but Gu Chen didn't hear what Lu Weiwei was saying just now.
For example, when a person is on the phone, he will catch whatever you hand him, and then look at you in confusion, not knowing what he is doing.
"Huh? What are you doing with a piece of white paper in your hand?" Officer Wang also hissed, sucked the wide noodles into his mouth, and couldn't help but let out a loud burp.
"This was brought from Liu Geng's house." Gu Chen also casually showed it to Officer Wang.
"Brought out by Liu Geng's family?" Officer Wang was also stunned. He stretched out his hand to take the white paper, and then asked: "Eh? Why are there some holes on it?"
"I'm not sure either." Gu Chen also shook his head, picked up his noodles and took a sip of soup.
In fact, Gu Chen couldn't tell, he just felt that these white papers shouldn't be in the living room.
Although I thought that these might be clues, I didn't think about their usefulness.
"Then don't think too much, let's wait for forensic doctor Liu's results to come out." Officer Wang was not in a hurry.
He knows why you can't eat hot tofu in a hurry.
However, the clues collected were limited. Gu Chen still didn't fully understand why the old lady was suddenly poisoned, and he didn't know what the problem was with those three so-called good people.
If someone deliberately poisons someone, what is the motive?
How can a blind old lady still expect to benefit from her? This is simply unrealistic.
In Gu Chen's opinion, there is really no hope for a family like Liu Geng.
Could it be that Liu Geng had a dispute with someone outside and the other party took revenge on his family?
But while chatting with his old classmate Zhuang Xiaohai, Gu Chen learned that this Liu Geng had quite a lot of connections near West Street Primary School Road.
It's also because I've been operating here for a long time, so if I say there's a feud, that's not the case.
"Junior brother Gu, I heard from Lao Wang that your police ID will be here soon." Seeing Gu Chen dazed there, seemingly unhappy, Lu Weiwei beside her quickly changed the subject.
Officer Wang smiled and said: "Originally, for you trainee police officers, the bureau intended to make you regular after one year, but you individually performed well, and there are many outstanding talents in the city, so the bureau decided to
I'll help you get a regular job in advance, and you may be notified soon."
"Junior Brother Gu, do your best, I'm optimistic about you." Lu Weiwei seemed even happier than Gu Chen.
"You know, Lu Weiwei's class lasted for a full year. You guys are considered the lucky ones."
After saying this, Officer Wang "hissed", then picked up a big bowl, poured the noodle soup into his stomach, and then said coquettishly: "I have another piece of news, I wonder if you are interested in hearing it.
"Old Wang, you are trying to hide yourself again, please tell me quickly." Lu Weiwei couldn't wait.
Seeing that Gu Chen had no response, Officer Wang asked again: "Oh! Gu Chen, do you want to know? If you want to know, I will tell you."
Gu Chen said "Oh" and then said: "Then you say it."
"Why do you feel that my police station is so cheap?" Officer Wang was also confused, but he still said: "I heard from friends in the police station that our Furong Police Station has been included in the first batch of reference lists for new branches, and I heard that,
Four to five new police stations will be established next, and the level of the police stations will be discussed again."
"Really or not?" Lu Weiwei was stunned at that time: "Then our Zhao director will laugh to death?"
"Yes, this is Zhao Suo's lifelong effort, so he should be very happy." Gu Chen was also attracted by this topic.
In the end, Officer Wang waved his hand and said: "We, Director Zhao, are not happy."
"Ah? You're not happy about this?" Lu Weiwei was also quite surprised and asked, "Why is this?"
"The branch has troubles." Police Officer Wang picked up a glass of water beside him, poured it into his mouth, and then said: "In the past, our Zhao Police Station dreamed of upgrading Furong Police Station to Furong Branch. After all, our Furong Police Station is the structure of the branch.
But there is no branch sign.”
"If it hadn't been for the increase in the migrant population in Jiangnan City in the past seven or eight years and the urgent need to increase institutions, we might not have had this opportunity yet."
"Then since it has been upgraded to Furong Branch, isn't Zhao Suo the branch director? Then shouldn't we, the backbone of the team, also have to be promoted to a higher level?" Lu Weiwei seemed to be quite interested in such a good thing.
"That's the problem." Officer Wang stretched out his index finger and said: "Once it is established as Furong Branch, we will definitely add four to five police stations. By then, our criminal investigation team and the backbone of other departments will have to all
Break them up and assign them to various police stations, and together with the personnel transferred from the city bureau, they will form the backbone of the new police station."
"Ah? Are we going to separate?" As soon as Lu Weiwei heard about the separation, she suddenly became less happy.
"If this is the case, Zhao Suo will indeed be a little reluctant to let go. After all, he brought out all his subordinates." Gu Chen also answered.
"That's right." Officer Wang also nodded and said: "Especially our three criminal investigation teams may have to be dispatched to different new police stations to form the core force of each major new police station. The previous personnel structure may be
, will also be reallocated."
"No wonder Suo Zhao put us on the honor roll and gave our third group to work hard to increase manpower. It turns out that Suo Zhao has been making plans for a long time? In this way, maybe two-thirds of the members of the third group may be sent abroad.
." Gu Chen also saw the problem.
In fact, when the three groups increased their manpower significantly, Gu Chen had a hunch that Zhao Guozhi might want to establish another criminal investigation group.
But now it seems that they are establishing a criminal investigation force for the new police station and reserving and training existing talents.
"As long as the three of us can be together, it doesn't matter where he goes." Lu Weiwei said indifferently: "Anyway, I will go wherever Junior Brother Gu goes."
"Hey, hey, this is a mountain to climb. It's no good." Officer Wang also quickly complained: "It's the decision of the higher-ups to arrange it. We just have to obey the orders absolutely."
It feels like Lu Weiwei is trying to pull a mountain, and she has the attitude of not marrying anyone but Gu Chen.
Officer Wang also saw through it but didn't say anything.
Lu Weiwei was a little unhappy, or felt a little uncomfortable.
Sure enough, Zhao Guozhi's worries were also his own worries.
"Have you finished eating? After finishing eating, let's go to the technical department of the city bureau and ask forensic doctor Liu for the results." Officer Wang was also about to take out his mobile phone.
Gu Chen stood up first and said, "This time I come, I can't always let Senior Brother Wang pay the bill."
Then Gu Chen walked to the counter and paid the noodles with his mobile phone.
…
…
Twenty minutes later.
The three of them drove to the Technical Section of the Municipal Bureau.
Why do you come here so often? Because in the process of dealing with forensic doctor Liu, the three of them knew a general rule.
That is, the harder you run, the easier it is to get results as quickly as possible.
Forensic medicine work is complex and tedious, and may involve processing various tests from all over the city in one day.
So children who cry have milk to drink.
If you simply rely on waiting, it may take longer.
Under normal circumstances, if you stay in the technical department, even if the technical department is inspecting other tasks, for the sake of face, they will try their best to prioritize your inspection report in the queue.
However, in the technical department, not all forensic doctors are as easy to talk to as Forensic Doctor Liu.
Other forensic doctors usually follow the procedure step by step and do as they should.
If there is a new test after get off work, if it is not particularly important, usually you will not work overtime, but will start the relevant test after work the next day.
But Forensic Doctor Liu is different. In terms of workaholic traits, he is somewhat similar to Gu Chen.
It is common to work overtime until late at night.
Therefore, those who worked as assistants under Dr. Liu also complained.
And there are often more police officers who often come to Forensic Doctor Liu's office to queue up for tea than other forensic teams.
No other reason, because Dr. Liu is a workaholic.
When Gu Chen, Officer Wang and Lu Weiwei came to the technical department, there were indeed some police officers handling the case standing at the door of Forensic Doctor Liu's office.
Everyone was standing in the hallway at the door, chatting about recent trivial matters.
Officer Wang stopped first and frowned: "It seems that Forensic Doctor Liu is very busy today."
"Old Wang, you tell me what to do, and we will listen to you." Lu Weiwei said.
"Let's go and take a look before we talk." Officer Wang didn't care too much and strode over directly.
"Eh? Lao Wang?" A third-level police inspector who was chatting couldn't help but said to Officer Wang.
"Lao Zhao, Lao Guan, Lao He, are you here too?"
"I haven't seen you, Old Wang, for a long time. I heard that you are doing well recently?"
"Everywhere, we serve the people."
"The Salted Fish King has turned over, and his tone of voice is completely different."
"Hey hey hey!"
Several people chatted together quickly...
While chatting with a few people, Officer Wang put his hands on his back and asked Gu Chen and Lu Weiwei to go in first.
At this moment, Forensic Doctor Liu was writing materials on his desk. When he saw Gu Chen and Lu Weiwei approaching, he also knew their purpose.
"You guys came here so quickly, my test report hasn't been finished yet." Forensic Doctor Liu also said slowly.
"Who doesn't know that Forensic Doctor Liu is very particular about work efficiency? We only need to know the key clues, and you can write the rest slowly. There is no rush." Lu Weiwei is also well aware of Forensic Doctor Liu's work order.
After the test is completed, he must first organize the information and write the test results into an easy-to-understand analysis report.
This is exactly what Forensic Doctor Liu is doing at the moment.
"What do you want to know?" Forensic Doctor Liu asked.
"Time of death, toxic substances." Gu Chen said.
Forensic doctor Liu adjusted his glasses and handed one of the information sheets to Gu Chen's hand, saying: "The deceased may have eaten poisonous lotus seed soup before his death. The time of death was this morning, probably... between nine and ten o'clock.
between."
"The time of death is in the morning?" Gu Chen was also quite surprised and quickly checked the information carefully.
"But we did not find food such as lotus seed soup in the deceased's home. We have looked for this many times." Lu Weiwei has a special say in this.
Because the entire filming record was completed by herself, Lu Weiwei had carefully checked all rooms and all places where toxic substances might appear.
She even checked under the bed, under the cupboards, and even around the bungalow.
The so-called lotus seed soup does not exist at all.
"Then I don't know. These are all your matters, and I have checked for you. The deceased did take lotus seed soup before his death."
Forensic doctor Liu took out another unfinished analysis report and said: "This is the component I initially extracted from the abdominal cavity of the deceased. The test results show that it is a toxic substance. This kind of toxicity is relatively severe and may cause human death."
Death immediately, I’m still analyzing the specific ingredients.”
"So, Liu Geng's mother was poisoned with lotus seed soup between nine and ten o'clock?" Gu Chen looked at Lu Weiwei beside him.
"Could it be those three kind-hearted aunts?" Lu Weiwei also questioned, saying: "After all, their statements are all connected together. If what they said is a collusion, it will be a big trouble."
"Senior Sister Lu, what you said is correct. I don't know the specific reason now. Maybe these three people are also very suspicious."
Gu Chen also lowered his head and thought for a few seconds. Suddenly he remembered the drill bit and the white paper with holes that he had found in the old lady's hand before, and he quickly took it out from his nine small items.
"By the way, Forensic Doctor Liu, if a blind person wants to communicate with others through letters, how should they do it?" Gu Chen asked.
Forensic Doctor Liu was stunned for a moment, and then said slowly: "I heard someone say before that there seems to be a special blind language in communication between blind people."
"Blind language?" When Gu Chen heard this word, his eyes suddenly lit up, and he quickly placed the blank paper and the drill on Dr. Liu's desk.
"What are you doing?" Forensic Doctor Liu was also stunned.
Gu Chen stretched out his hand: "Can you see if this is blind language?"
Forensic Doctor Liu raised his eyes, held the white paper in his hand, frowned, and asked Gu Chen, "Where did you get this?"
"I found it in the living room of the deceased. I had doubts about these small holes at the time. In addition, when the deceased was sent to the hospital, he was holding this drill tightly in his hand. I thought it was the old lady who suddenly suffered a heart attack while doing needlework.
Onset of illness."
Gu Chen informed Forensic Doctor Liu exactly what happened to him in the hospital and the deceased's home.
"It seems that your conjecture is completely correct." Forensic Doctor Liu suddenly turned on his computer and searched for some files in a database where the information was stored.
Soon, he clicked on one of them, stood up quickly, and walked towards the database in the cubicle.
Not long after, Forensic Doctor Liu took out an old book and came to Gu Chen.
"What is this?" Gu Chen asked.
"A basic tutorial on Braille." Forensic Doctor Liu said.
Lu Weiwei was shocked and said: "Forensic Doctor Liu, why do you have everything? Are you more reliable than a library?"
"No." Forensic Doctor Liu also waved his hand and said: "More than ten years ago, a blind man came to report a crime and later left this book in the business office."
"My colleagues originally thought of putting it in a drawer and waiting for the blind man to come and pick it up, but they never did. Later, my colleagues threw the book to me and asked me to put it in the reference room."
"I originally thought I wouldn't be able to use it in my lifetime, but now it seems that it will be of some help to you, Gu Chen."
Gu Chen didn't say anything. He took the "Beginner's Course in Braille" from Forensic Liu's hand, quickly found a seat to sit down, and then started to flip through it quickly.
Lu Weiwei also ran over quickly.
"Braille is text that relies on tactile perception. It is composed of different combinations of raised dots made on paper through Braille boards, Braille machines, etc."
"The Braille characters in each square of Braille are composed of six dots, plus blank spaces, for a total of 64 variations."
"Braille can also represent mathematical symbols and musical symbols."
“The greatest feature of inventor Braille’s Braille is that it can be both read and written.”
Gu Chen silently recited the theories in the "Beginner's Guide to Braille" while sorting the holes on the paper and began to quickly browse through them.
Lu Weiwei was also stunned and said: "Junior Brother Gu, do you think the holes on these papers are really Braille?"
"If there is no other better explanation, I would rather believe that this is true." Gu Chen also nodded and said, "Old lady...she must want to tell us the so-called truth."
