Chapter 70 Killing Two Birds with One Stone
At six o'clock in the morning, colleagues in the forensic department who had been busy all night went home from get off work again, praying in their hearts that there would be no more murders in the morning that would call them back to work overtime.
The doorman downstairs fell asleep on the table in the reception room, and Xu Yiqing didn't wake him up when he passed by.
Anyway, there are no valuables in the Forensic Medicine Department, and even organ dealers would not be interested in this place. After all, most of the corpses in the morgue are in horrible condition. Even if there are some that are intact on the outside, their internal organs have been dissected.
After not sleeping all night, Xu Yiqing dozed off in the office of the Criminal Police Brigade.
He was groggy, and he heard someone calling his name.
"Old Xu, Old Xu!"
"Huh?"
Xu Yiqing came back to her senses and looked at Du Yu, who was sitting opposite him.
Du Yu also had obvious dark circles under his eyes. It turns out that yawning is contagious, and he couldn't help but open his mouth wide.
"Old Xu, you should go back after you have been sleepy for a while." Du Yu sighed softly: "If you keep enduring like this, sooner or later your body will not be able to bear it anymore."
They are no longer young men in their twenties. With these years of work, Du Yu has become increasingly aware that he is not as good as before.
When he first joined the job, he felt that he had endless energy and needed two people to squat in shifts. He could squat for two days without sleep by himself, and then he could run two streets to chase the suspect who had just come out of the hotel.
But now, as long as he doesn't sleep for one night, his heartbeat will feel a little faster the next day, and he can't concentrate.
Xu Yiqing shook his head. He must have been distracted by fatigue just now. After he regained consciousness, he quickly asked: "Where did you just talk about?"
Du Yu said: "Poisoning, you said Song Lang died of poisoning."
"Yes, the sodium ion concentration in the blood test was wrong. Coupled with the sudden cardiac arrest, I and Asheng discussed it and concluded that it was nerve paralysis caused by aconitine poisoning, which in turn led to death from myocardial infarction."
< br>
"Why is it not written in the report?"
Du Yu rubbed the corners of his eyes and looked at the computer. He opened the autopsy report document that Xu Yiqing had just sent him and said, "It only states the cause of death was cardiac arrest."
"Because the autopsy report has not been completed yet, I cannot draw an accurate conclusion. What is written in the document is only the cause of death given by the hospital."
After working with Xu Yiqing for so long, Du Yu immediately understood what he meant: "Is there any doubt about the cause of death?"
Xu Yiqing nodded: "The time is not right. He will die within half an hour of aconitine poisoning. Even people with poor physical constitution will react within a few minutes of poisoning. Their face will be pale, their expressions will be convulsed, and they will sweat all over."
"Similar to the symptoms Song Lang had before his death."
Du Yu recalled how the police suddenly noticed something was wrong with Song Lang in the middle of the night, which was consistent with the symptoms of poisoning described by Xu Yiqing at that moment.
But as Xu Yiqing said, the time just didn't match up.
At 20:40 in the evening, they set off from the nightclub and returned to the Criminal Police Brigade.
At 21:05, Song Lang said he was a little hungry, and the police went to the canteen to get him a lunch box. Du Yu remembered it clearly. At that time, he glanced at his watch and wondered in his mind what dishes were left in the canteen.
At 21:45, Xu Yiqing and Song Lang left the criminal police brigade after chatting. Song Lang, led by the police, went to the room arranged for him and lay down in it playing with his mobile phone.
At 22:00, Xu Yiqing returned to the forensic department to work overtime and was almost locked in the morgue by the guard all night.
At 22:30, Song Lang, who had already rested, suddenly felt very uncomfortable and had an upset stomach. He went to the police on duty for help.
22:40 Xu Yiqing received a call from Du Yu and went to the hospital.
At 23:00 sharp, Jiangcheng City People's Hospital announced that Song Lang died due to cardiac arrest due to ineffective rescue efforts.
Du Yu absolutely believed in Xu Yiqing's professionalism. After Xu Yiqing's autopsy, no other fatal injuries or internal injuries were found. Poisoning should be the most accurate cause of Song Lang's death.
But the poison detected in the blood test is contrary to the existing clues.
Du Yu said: "As you said, Song Lang only became abnormal at 10:30 in the evening, so he should have been poisoned after you left. But at that time, Song Lang didn't even talk about eating, and he didn't even drink saliva. He claimed that he drank a little too much and just wanted to pee, but he was not thirsty at all.”
Xu Yiqing frowned when he heard this: "Is it wine?"
He quickly dismissed this view of his own.
He also drank the wine made by Song Lang. Even if the bottle of wine was poisoned, there should be aconitine in the whole bottle. There was no reason that the wine Song Lang poured for him was poisonous, and the wine he drank was not poisonous.
Du Yu rubbed his shoulders: "If I can determine when she was poisoned, I can catch that crazy woman."
If the food is poisonous, everyone who comes into contact with the food will be controlled, including chefs, waiters and even those who deliver food and farmers.
If there is poison in the wine, just ask the wine maker, the wine delivery person, and the person who serves the wine, and you can always find the murderer.
Rather than saying that this is what the police do, it would be better to say that Du Yu's strength is catching people through clues... and chasing the murderer with hand-to-hand combat.
"I'm not going back now. I'm just going to rest here for a while." Xu Yiqing glanced at his watch: "Eight o'clock...forget it, let's go to nine o'clock. Let's go to Song Lang's store. We saw it since yesterday. Song Lang started to go back through the timeline, and he could always find the time period when he was poisoned."
Du Yu nodded, and then said to Xu Yiqing in a very serious tone: "Old Xu, I will aggrieve you from now on. You can only drink unopened bottled water, and you can also eat canned food. . After all, poisoning is a matter of deliberate calculation and unintentional, and it is impossible to prevent it.”
Before Song Lang's accident, the task force followed the previous [Cleaner]'s crime style and focused on her killing people herself.
Li Yueyue was killed with a knife and then beheaded by her, Li Cheng's whole family was set on fire by her, He Yunke was hacked to death by her with a kitchen knife, and as expected, the principal of No. 4 Middle School also had his throat cut with a dagger.
In addition, [Cleaner] had appeared in public for a long time pretending to be Zou Yi, so before Song Lang died, the task force was wondering what identity she would disguise herself as to approach Song Lang and kill him this time.
I didn't expect it to be poisoned.
——
Xu Yiqing and Du Yu lay on the table for three hours, seizing any fragmented time to rest, and then went to Song Lang's store at nine or ten.
Zhou Shi and Lin Sheng also received the news and came together. The former was responsible for recalling every detail of everyone last night and profiling under what circumstances he would take action if he were the murderer.
The latter brought professional tools to preserve possible evidence and send them to the laboratory for analysis at any time.
And in Du Yu's words, now we need more clarity of mind. With the state of running around with Lao Xu, it is inevitable that there will be times when we get confused.
But if Zhou Shi is here, then they can rest assured.
To their surprise, in addition to the police, there was another group of people standing in front of Song Lang's store when they arrived.
Li Dusheng stood silently at the door of the store, silently looking through the window at the deserted store with the lights off.
"Li Dusheng." Du Yu was obviously surprised when he saw him. He was stunned for a moment, and then his expression became a little complicated.
Hearing this, Li Dusheng turned his head and looked at the two of them, his face expressionless, but there was a hint of sadness in his eyes.
"Little Wolf... is dead."
This is not a question, but a statement based on fact.
Not to mention how quickly Li Dusheng obtained the information in Jiangcheng, Jiangcheng City People's Hospital alone had to notify the family of the deceased first.
So Li Dusheng had already received the news of Xiaolang's death last night.
Hearing that the police had come to the store this morning, he rushed over in person without saying a word.
Du Yu noticed that Li Dusheng's face was also very tired. He must have not slept well after receiving the news of Song Lang's death last night.
Last night he had dinner with several local business owners in Jiangcheng. There was supposed to be a second entertainment event after the meal. Near eleven o'clock, he received a call from Song Lang's wife, saying that Song Lang was dying in the hospital. Li Dusheng immediately abandoned his business there and rushed to the hospital. When he learned that Song Lang's body had been sent to the forensic department for autopsy, he went back home and waited until now.
After dealing with Li Dusheng for so many years, Du Yu knew very well who he was.
The fact that he could endure it until now instead of going to the police station to demand an explanation last night shows that he still has a brain.
It was precisely because of Li Dusheng's calmness at this time that Du Yu felt a little guilty.
The person was taken away by himself, then something happened to him at the police station, and he died in the hospital.
Asking himself, Du Yu felt that he was responsible.
But Li Dusheng obviously didn't want to hear what he said, but looked at Xu Yiqing.
"Doctor Xu, how did Little Wolf die?"
Xu Yiqing said: "The specific cause of death is still unclear... I personally think it was poisoning."
"Poisoned."
Li Dusheng was stunned when he heard this. It was obvious that this answer was beyond his expectation.
Check out the 16-9 book bar and see the correct version!
"Poisoned...then there is nothing we can do."
Immediately afterwards, everyone felt a sense of relief in him...
No one knew why Li Dusheng felt relieved.
Only he knew that if he died of poisoning, he would not have to offend the police for the sake of his loyalty and to give an explanation to his subordinates.
Since his sister's death, Li Dusheng's thoughts in his heart have quietly changed. He desperately wants to have a proper status, both for himself and for the brothers who follow him to eat.
In addition, attending the ribbon-cutting ceremony of Fumei Group at the beginning of the year made him even more aware that there is no benefit in going against the government.
There is no way to avoid getting your shoes wet when you often walk by the river. Although he is always prepared for this, Li Dusheng still wants to try to see if he can find a new way to clear himself in this society.
"It's impossible to prevent poisoning. Even you guys can't do anything about it..." Li Dusheng looked at Du Yu: "I am self-aware, Sir Du. I can't save Xiaolang in the police station, and I don't have the ability."
When he said this, he seemed to have aged another year and sighed heavily.
"Little Wolf...he is my favorite youngster. He shouldn't have died so early. It was me who hurt him."
Xu Yiqing didn't understand, so Zhou Shi whispered in his ear that this was the dialect in Hong Kong City.
He was about to say something when he suddenly stopped speaking, which attracted Li Dusheng's sideways glance. However, seeing that his benefactor was only looking at him and not saying anything else, he moved his gaze to the side.
"Captain Du, come here."
"What's wrong, Lao Xu?"
Xu Yiqing pulled Du Yu aside and whispered: "I saw Li Dusheng blaming himself just now. I wanted to comfort him and say that Song Lang's death had nothing to do with him... He thought Song Lang was poisoned by an enemy seeking revenge. .”
Du Yu said: "Just tell him, Song Lang was not implicated by him. [Cleaner] killing Song Lang should have something to do with Song Lang himself... Ever since I learned that Song Lang also graduated from No. 4 Middle School, I am even more sure ”
The suspect with mental illness had animosity with Song Lang. After Zhou Shi's profile, the crime team focused their investigation on the fact that Song Lang used to attend No. 4 Middle School.
Song Lang graduated from No. 4 Middle School, and the principal of No. 4 Middle School was his former class teacher. Now they are both dead. This is definitely not a coincidence.
Xu Yiqing shook his head with a serious expression: "I don't think it's that simple. At that moment, I suddenly realized something... [Cleaner] had many opportunities to kill Song Lang, and she killed him easily. Why did she Not using hands, but using poison? ”
Poisoning someone to death is common in situations where one is not confident in one's abilities, such as there is a huge disparity in strength, such as not having the guts to kill, or the need to act covertly.
These conditions obviously do not meet the requirements of [Cleaner]. The opponent is a killer who has received foreign combat training, is proficient in various counter-reconnaissance techniques, is thoughtful and ruthless.
She wanted to kill Song Lang, but there were ten thousand ways to do it easily. Zhou Shi once profiled [Cleaner]. A woman who is good at psychology, disguise and murderous methods will only believe her own eyes.
He will only believe in the lifeless corpse before his eyes.
Zhou Shi even speculated that in the Basia Village fire case, after the [cleaner] set the fire, he hid near Li Cheng's house until he heard the sound of the fire siren and then disappeared into the woods around the village to ensure that no one came out of the fire alive!
But why did she choose to poison this time with the most unsafe and least guaranteed results?
Du Yu also showed a puzzled expression.
Xu Yiqing continued: "Obviously, [the cleaners] knew that we would protect Song Lang after the death of the principal of No. 4 Middle School. The best way is to remove Song Lang after the suspect announced that the second person to die was Song Lang. He was taken to the police station for protection and if she poisons Song Lang again, the responsibility will be on us.”
Du Yu's face changed as he realized what responsibility Xu Yiqing was talking about.
"[The cleaner] knew very well that Song Lang was Li Dusheng's favorite brother. Song Lang died in the police station. Li Dusheng would think that we were responsible for Song Lang's death, and then have a conflict with us... She wanted to get rid of Li Dusheng? ! ”
A normal person would not think that the police would be in danger if gangs clashed with the police.
You need a reason to crack down on organized crime, but you only need a list to fight against terrorism.
So as long as Li Dusheng is a little less calm and not a sensible person, and he conflicts with the police for Song Lang, it will be Li Dusheng who is uprooted in the end.
[Cleaner] has such a big appetite!
Du Yu's eyes were solemn: "What exactly does she want to do? There have been four cases in two years, three against Fumei Group and two against Li Dusheng."
The victim of the headless corpse case was Li Dusheng's sister.
Li Cheng, who died in the Basia Village fire incident, and his accomplices secretly seized land in the village and sold it to the Fumei Group.
The deceased in the corpse-hiding case was the regional director of Fumei Group in Jiangcheng.
The current serial case kills two birds with one stone, targeting both parties:
The principal of No. 4 Middle School cooperates with Fumei Group and uses their money to expand student enrollment, reform No. 4 Middle School education, and plans to build No. 4 Middle School into the best junior high school in Jiangcheng.
As long as it succeeds this time, Fumei Group will still expand its influence in Jiangcheng.
But the principal of No. 4 Middle School died and the enrollment expansion was put on hold. Parents would no longer send students to No. 4 Middle School.
Song Lang was Li Dusheng's favorite younger brother. He was poisoned to death in the police station.
Li Dusheng almost had a conflict with the police. If it weren't for his trust in Xu Yiqing's autopsy skills and his awareness of the overall situation, the people at the door of the nightclub would have probably already started a confrontation with the police.
If this is the case, the direct consequence will be that the province will launch a special operation against Li Dusheng, and eventually he and his gang will disappear in Jiangcheng.
Du Yu and Xu Yiqing suddenly realized that this crazy woman who was killing people everywhere was not killing people indiscriminately, nor was she just helping unrelated suspects to hide their identities and assist in committing crimes.
[Cleaner] selects suspects worthy of his help and fulfills their "wish" while actually having a very strong purpose——
Fumei Group and Li Dusheng!
Xu Yiqing also told Zhou Shi his conjecture.
At the entrance of the alley next to the nightclub, after the three members of the task force were silent for a long time, Zhou Shi suddenly came up with a hypothesis.
"For so long, we have all believed that [the cleaner] is the real culprit behind these serial cases... Of course, I am not saying that she is not, but I am thinking, is it really just a conflict between an individual and an organization?"< br>
Zhou Shi said: "No matter how powerful [the cleaner] is, he can't accurately find so many suspects who have a grudge against his target in Jiangcheng. Let's help them commit the crime."
Xu Yiqing asked: "You mean someone is also helping [the cleaners]?"
Zhou Shi said: "It's just a guess. After all, there are many people in that old group photo."
