Chapter 70 1 stone 2 birds
Chapter 70 Killing two birds with one stone
At six o'clock in the morning, colleagues from the Forensic Department, who had been busy all night, went home after get off work. They prayed in their hearts that there would be no more murder cases in the morning that would require them to come back to work overtime.
The security guard downstairs fell asleep on the table in the message room, and Xu Yiqing did not wake him up when he passed by.
Anyway, there are no valuables in the Forensic Department, and even organ dealers would not target this place. After all, most of the bodies in the morgue are in a horrible state, and even if there are some that look intact, their internal organs have already been dissected.
After a sleepless night, Xu Yiqing dozed off in the office of the Criminal Police Brigade.
He was drowsy and heard someone calling his name in a trance.
"Lao Xu, Lao Xu!"
"Ok?"
Xu Yiqing came back to his senses and looked at Du Yu who was sitting opposite him.
Du Yu also had obvious dark circles under his eyes. It turned out that yawning was contagious, and he couldn't help but open his mouth wide.
"Lao Xu, you're tired now. Go home after you're done." Du Yu sighed, "If you keep doing this, your body will give out sooner or later."
They are no longer young men in their twenties. As they work over the years, Du Yu has become increasingly aware that he is not as good as he used to be.
When he first started working, he felt that he had endless energy. He needed two people to take shifts to stake out a place. He could stake out a place by himself for two days without sleeping, and then he could run across two blocks to chase a suspect who had just come out of a hotel.
But now, if he doesn’t sleep for one night, he will feel his heart beating faster and he can’t concentrate the next day.
Xu Yiqing shook his head. He must have been too tired to resist and was distracted. After waking up, he quickly asked, "Where were we talking about just now?"
Du Yu said: "Poisoning, you said Song Lang died of poisoning."
"Yes, the sodium ion concentration in the blood test was wrong, and coupled with the sudden cardiac arrest, after discussing with Ah Sheng, I believe that it was nerve paralysis caused by aconitine poisoning, which in turn led to myocardial infarction and death."
“Why isn’t it in the report?”
Du Yu rubbed his eyes and looked at the computer. He opened the autopsy report document that Xu Yiqing had just sent him and said, "It only says that the cause of death was cardiac arrest."
"Because the autopsy report has not been completed, I cannot give an accurate conclusion. The document only contains the cause of death given by the hospital."
Having worked 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 doesn't match. Aconitine poisoning can kill people in half an hour. Even people with poor physical constitutions will react after a few minutes of poisoning. Their faces will turn pale, their expressions will twitch, and they will sweat all over."
"Same symptoms as before Song Lang's death."
Du Yu recalled how the police suddenly discovered that something was wrong with Song Lang in the middle of the night, which matched the symptoms of poisoning that Xu Yiqing described at this moment.
But just like Xu Yiqing said, the timing doesn't match.
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, so the police went to the canteen to get him a box lunch. Du Yu remembered it very clearly. At that time, he looked at his watch and wondered what dishes were left in the canteen.
At 21:45, Xu Yiqing finished chatting with Song Lang and left the Criminal Police Brigade. Led by the police, Song Lang went to the room arranged for him and lay there 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 for a whole night by the security guard.
At 22:30, Song Lang, who had already rested, suddenly felt very uncomfortable and had stomach discomfort, so he went to the police officer on duty for help.
22:40 Xu Yiqing received a call from Du Yu and went to the hospital.
At 23:00, Jiangcheng People's Hospital announced that Song Lang had died of cardiac arrest after failed rescue efforts.
Du Yu absolutely believed in Xu Yiqing's professional level. 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.
However, the poison detected in the blood test was inconsistent with the existing clues.
Du Yu said, "Like you said, Song Lang showed abnormal behavior at 10:30 p.m., so he should have been poisoned after you left. But at that time, Song Lang didn't even drink water, let alone eat. He claimed that he drank a little too much and just wanted to pee, not thirsty at all."
Xu Yiqing frowned when he heard this: "Is it wine?"
He quickly disavowed his own view.
He also drank the wine that Song Lang mixed. Even if the wine was poisoned, the whole bottle should contain aconitine. It is not possible that the wine Song Lang poured for him was poisonous and the wine he drank was not poisonous.
Du Yu rubbed his shoulders and said, "If I can determine when she was poisoned, I can catch that crazy woman."
If the food is poisonous, control everyone who has come into contact with the food, including the chefs, waiters, and even the people who deliver the food and farm workers.
If the wine is poisonous, ask the person who brews it, delivers it, and serves it, and you will always find the culprit.
Rather than saying that this is what the police do, it is better to say that Du Yu’s strength is to catch people through clues... and to chase criminals in physical combat.
"I won't go back yet. I'll just rest here for a while." Xu Yiqing glanced at his watch: "Eight o'clock... Never mind, nine o'clock. Let's go to Song Lang's store and follow the timeline from the day we met Song Lang yesterday. We can always find out when he was poisoned."
Du Yu nodded, and then said to Xu Yiqing in a very serious tone: "Old Xu, I'm sorry to have to bear with you from now on. You can only drink unopened bottled water, and eat canned food. After all, poisoning is something that can be done intentionally or unintentionally, and it is hard to guard against."
Before Song Lang got into trouble, the task force focused on preventing the Cleaner from killing people personally, based on her previous crime style.
Li Yueyue was killed by her with a single knife and then beheaded, Li Cheng's entire family was burned to death by her, He Yunke was hacked to death by her with a kitchen knife, and as expected, the principal of No. 4 Middle School was also slit in the throat by her with a dagger.
In addition, the [Cleaner] had once appeared in public as Zou Yi for a long time, so before Song Lang's death, the task force was wondering what disguise she would take on this time to approach Song Lang and kill him.
I didn't expect it was poison.
-
Xu Yiqing and Du Yu lay on the table for three hours, taking advantage of any fragmented time to rest, and then went to Song Lang's shop at 9:10.
Zhou Shi and Lin Sheng also received the news and came together. The former was responsible for recalling every detail of what happened last night and profiling under what circumstances he would act if he were the murderer.
The latter brought professional tools to preserve possible evidence and send it to the laboratory for testing at any time.
And in Du Yu's words, they need to be more clear-headed now. With the non-stop work he and Lao Xu do, it is inevitable that they will make mistakes sometimes.
But if Zhou Shi was there, they would feel relieved.
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 at the door of the store in silence, looking through the window at the deserted, lights-off store.
"Li Dusheng." Du Yu was obviously surprised to see him. He was stunned at first, and then his expression became a little complicated.
Hearing this, Li Dusheng turned around and looked at the two of them. There was no expression on his face, 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 information in Jiangcheng, the Jiangcheng 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.
When he heard that the police came to the store this morning, he rushed over in person without saying a word.
Du Yu noticed that Li Dusheng looked 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. He was supposed to have another entertainment activity after dinner. At about 11 o'clock, he received a call from Song Lang's wife, saying that Song Lang was dying in the hospital. Li Dusheng immediately dropped his business and rushed to the hospital. When he learned that Song Lang's body had been sent to the forensic department for an autopsy, he returned home and has been waiting until now.
Having dealt with Li Dusheng for so many years, Du Yu knows very well what kind of person he is.
The fact that he was able to endure until now instead of going to the police station to ask for an explanation last night shows that he still has some brains.
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 at the police station, and finally he died in the hospital.
If he were to ask himself honestly, Du Yu would feel that he was responsible.
But Li Dusheng obviously didn't want to hear what he said, and looked at Xu Yiqing instead.
"Doctor Xu, how did Xiaolang 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 expectations.
"Poisoned... There's nothing we can do about it."
Then, everyone felt a sense of relief from him...
No one knew why Li Dusheng felt relieved.
Only he himself knew that if he died of poisoning, he would not have to offend the police for the sake of his sense of loyalty and to give an explanation to his subordinates.
Ever since his sister died, Li Dusheng's thoughts have actually been quietly changing. He urgently wants to have a legitimate status for himself and for the brothers who depend on him for a living.
In addition, his participation in the ribbon-cutting ceremony of the Fumei Group at the beginning of the year made him realize even more clearly that there is no benefit in going against the government.
If you walk by the river, you will get your feet wet. Although he is always prepared in his heart, Li Dusheng still wants to give it a try to see if he can find a new way to clear himself in this society.
"Poisoning is hard to prevent. Even you cops can't do anything about it..." Li Dusheng looked at Du Yu: "I know myself well, Du Sir. If the police station can't protect Xiaolang, I don't have the ability to do so."
As he said this, he seemed to have aged a year and sighed heavily.
"Little Wolf... He was my favorite young man. He shouldn't have died so early. It's my fault."
Xu Yiqing didn't understand, so Zhou Shi whispered in his ear that this was the dialect from Hong Kong City.
He was about to say something when he suddenly stopped talking, which attracted Li Dusheng's sidelong glance. But when he saw that his benefactor was just looking at him and didn't say anything else, he shifted his gaze to the side.
"Captain Du, come here for a moment."
"What's wrong, Lao Xu?"
Xu Yiqing pulled Du Yu aside and whispered, "Just now I saw Li Dusheng blaming himself. I wanted to comfort him and tell him that Song Lang's death had nothing to do with him... He thought Song Lang was poisoned to death by his enemies who were seeking revenge."
Du Yu said, "Just tell him that Song Lang was not implicated by him. The cleaner's killing of Song Lang must have something to do with Song Lang himself... Since I learned that Song Lang also graduated from No. 4 Middle School, I am even more certain."
After Zhou Shi's profiling of the hatred between the mentally ill suspect and Song Lang, the serious 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 that school was his former class teacher. Now they are both dead, and this is definitely not a coincidence.
Xu Yiqing shook his head, his expression serious: "I don't think it's that simple. Just now, I suddenly realized something... [Cleaner] had many opportunities to kill Song Lang and could have killed him easily. Why didn't she use her hands, but used poison?"
Poisoning someone to death is common when one is not confident in one's own abilities, such as when there is a huge disparity in power, when one does not have the courage to kill, or when one needs to act in secret.
These conditions obviously do not meet the requirements of the [Cleaner], who is a killer who has received combat training abroad, is proficient in various anti-reconnaissance techniques, is meticulous and ruthless.
She wanted to kill Song Lang, and there were ten thousand ways to do it easily. Zhou Shi had profiled the "Cleaner", a woman who was good at psychology, disguise and killing methods, and only believed her own eyes.
He would only believe in the lifeless corpse before his eyes.
Zhou Shi even speculated that in the case of the fire in Baxia Village, after the [cleaner] set the fire, he hid near Li Cheng's house until he heard the sound of the fire sirens and then disappeared into the woods around the village to make sure that no one walked out of the fire alive!
But why did she choose to use the most unreliable and least effective method of poisoning this time?
Du Yu also showed a puzzled expression.
Xu Yiqing continued, "It's obvious that the [cleaner] knew that we would protect Song Lang after the death of the principal of No. 4 Middle School. The best way is to take the suspect to the police station for protection after he announced that Song Lang was the second person to die. If she poisoned Song Lang to death at this time, the responsibility would be on us."
Du Yu realized what responsibility Xu Yiqing was talking about and his expression changed.
"The Cleaner knows very well that Song Lang is Li Dusheng's favorite little brother. If Song Lang dies in the police station, Li Dusheng will think that we are responsible for Song Lang's death and then conflict with us... She wants to get rid of Li Dusheng?!"
Any normal person would not think that the police would be in danger if gangs clashed with them.
Cracking down on organized crime requires a reason, but fighting terrorism only requires a list.
Therefore, as long as Li Dusheng is not so calm and is not a sensible person, and he clashes with the police over Song Lang, it will be Li Dusheng who will be uprooted in the end.
The [Cleaner] has such a big appetite!
Du Yu's eyes were serious. "What on earth does she want to do? Four cases in two years, three against Fumei Group and two against Li Dusheng."
The victim of the headless dismemberment case was Li Dusheng's sister.
Li Cheng, who died in the fire case in Baxia Village, and his accomplices seized the village’s land by force and sold it to the Fumei Group.
The victim in the statue corpse case was the regional director of Fumei Group in Jiangcheng.
This serial case is killing two birds with one stone, targeting two parties:
The principal of No. 4 Middle School has cooperated with the Fumei Group. He took their money and planned to expand the enrollment of students, reform the education of No. 4 Middle School, and build No. 4 Middle School into the best junior high school in Jiangcheng.
As long as this is successful, Fumei Group will still expand its influence in Jiangcheng.
But the principal of No. 4 Middle School has passed away, the expansion of enrollment has been shelved, and no parents will send their children to No. 4 Middle School anymore.
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 he hadn't trusted Xu Yiqing's autopsy ability and hadn't had a good sense of the overall situation, the people at the entrance of the nightclub would probably have confronted the police.
If this is true, the direct consequence is that the province will launch a special operation against Li Dusheng, and eventually he and his men will disappear from Jiangcheng.
Du Yu and Xu Yiqing suddenly realized that this crazy woman who was killing people everywhere was not killing indiscriminately, nor was she just helping those unrelated suspects to hide their identities and assist in committing crimes.
[Cleaner] While selecting suspects who are worthy of his help and fulfilling their "wishes", he actually has a strong purpose -
Fumei Group and Li Dusheng!
Xu Yiqing also told Zhou Shi his guess.
At the entrance of the alley next to the nightclub, after a long period of silence, Zhou Shi suddenly put forward a hypothesis.
"For so long, we have all believed that [the cleaner] is the real culprit behind these serial cases... Of course, I'm not saying she isn't, but I'm wondering, is this really just a conflict between an individual and an organization?"
Zhou Shi said: "No matter how powerful the [Cleaner] is, he can't accurately find so many suspects who have grudges against his target in Jiangcheng and help them commit crimes."
Xu Yiqing asked, "Are you saying that someone is also helping the [cleaner]?"
Zhou Shi said: "It's just a guess. After all, there are many people in that old photo."
