There is a case, an old man, gas poisoning, are you coming I forgot, the murder is in the second group, you two have a good rest, please ignore me The deceased is Ji Shanzhi's mother, and said with a smile that Ji Shanzhi is related to the case you are investigating What the situation Do I need help you get the case to a team?
I've started an autopsy, waiting for your news In Wu Duan's mind, countless thoughts flew by. \ Ji Shanzhi's mother died of gas poisoning Was it an accident, a suicide, or a homicide Why is it at this time why Ji Shanzhi was just involved, and his mother had such a thing Does he know that someone informed him Wu Duan flipped down and looked at the chat history and saw Yan Sixian's reply.
The case is transferred to a group Don't inform Ji Shanzhi just yet The two short instructions are the same as Wu Duan's thoughts.
Yan Sixian seemed to have made a lot of determination before sitting up.
He was afraid that he would miss the bed, so he almost jumped out of bed and walked to the bathroom without looking back.
A sentence popped up in Wu Duan's mind: A real man, never look back at the bed.
This made Wu Duan squat on the carpet with a smile.
"Early in the morning, what kind of wind are you smoking" Yan Sixian said inarticulately while holding a toothbrush.
"No," Wu Duan waved his hand and said, "Next time, get up slowly, you are so easy to die suddenly." ” Yan Sixian squirted out a mouthful of foam, "You look forward to Dad's order" Five minutes later, the two went out.
The smog is shrouded, and the sky should be bright, but it can't be seen through.
Traveling in such weather, it won't be long before your lungs feel hot.
It's a faint feeling, but it definitely makes you worry and make you wonder if you're going to die of lung cancer in the next second.
Therefore, when he went out, Yan Sixian brought a pack of anti-haze masks, one for Wu Duan and one for himself, and put the rest in the car for backup.
On the way, Wu Duan kept holding Yan Sixian's mobile phone to watch the information of the case summarized by all parties, and the two did not talk until 20 minutes later, Yan Sixian's car was parked in the underground parking lot of the Municipal Bureau.
Wu Duan asked, "You asked people to bring Ji Shanzhi here?"
"Hmm."
Yan Sixian nodded, "The people I picked up overnight last night should be half of the nature of detention and protection." ” Seeing that Wu Duan was silent, Yan Sixian said: "I'll talk about his mother's affairs." ” He didn't want Wu Duan to be this bad guy.
Wu Duan shook his head, "I'll go, I have to be in front of me."
He must have wished he had an acquaintance here. ” Yan Sixian didn't insist anymore.
The thought of informing an unfortunate person of such unfortunate news made both of them feel heavy in their hearts.
After getting out of the elevator, Yan Sixian said again: "Then you talk to him and I'll go to the meeting."
"Hmm."
The two walked with their backs, took two steps, and Wu Duan turned around and said, "Hey, don't lock the door of the conference room." ” "Got it, leave the door for you."
Conference room.
The criminal policemen who had been busy all night had the air of dust and dust, their hair was messy, their clothes were full of wrinkles, and they were obviously lying on their stomachs or kneeling to carry out some trace examination.
Yan Sixian is no longer surprised by everyone's fatigue, and the only thing he can do is to lead everyone to solve the case as soon as possible.
But what is different today is that Yan Sixian saw the meaning of dissatisfaction on some people's faces.
Bureau Zhao personally ordered that the second detachment was responsible for the vicious case for the time being, and the criminal policemen of the first team were finally able to rest for a few days, but at this time, the Yan team took back a case.
What's wrong with Team Wu, you, the boy who came in by connections, want to do something You're not short of money, so why don't you be so active for a few days?
Although they didn't speak, Yan Sixian was shrewd, and at a glance, he could roughly understand the twists and turns in these people's minds.
Yan Sixian pretended not to notice their emotions and tapped the table with his knuckles, signaling everyone to concentrate.
"Let's talk about the report first."
Yan Sixian said.
A criminal policeman raised his hand and answered: "At 9:16 last night, the Pingyang Road Police Station received the police and said that a family had a suspicious smell.
After receiving the police, the police rushed to check and found that the person who reported the crime was a neighbor who lived across the door from the house where the crime occurred.
According to the neighbors, the opposite door is an old lady who lives alone, about a week ago, there was a smell, but it is not too serious, they thought it was caused by the old lady littering, so they didn't take it seriously, but the smell got bigger and bigger, they contacted the property, and the property could not determine the source of the smell, but still tried to knock on the door of the house where the crime occurred.
No one answered.
The property had to promise that they would find a way to solve the problem.
In the next two or three days, the property tried to find the source of the smell, and knocked on the door of the house where the crime occurred several times, but no one answered, and they also tried to contact the owner, but the mobile phone was always unanswered.
Until last night, the smell was too big, and the neighbor on the other side, the informant, had a few quarrels with the property, and called the police in a fit of anger.
It was an experienced police officer who rushed to check the situation, who had dealt with carrion corpses, and when he arrived at the place, he felt that something was wrong, so he urgently contacted the person from the lock-picking company, opened the door and entered the house, and found a highly decomposed corpse in the bedroom."
A criminal police officer raised his hand and interrupted, "Let me tell you about the situation at the scene of the inquest." ” Yan Sixian glanced at the criminal policeman who spoke.
His name is Qu Yuan, he entered the city bureau a year earlier than Wu Duan, and his seniority in the first team is not shallow, and he is one of the few people who showed dissatisfaction just now.
No one answered Qu Yuan's words, so he said to himself: "The person was lying on the bed at the time, all in a supine position, wearing autumn clothes on the upper body, only underwear on the lower body, covered with a quilt, and his head exposed outside the quilt, so it is inferred that the person died while sleeping."
There were no signs of a fight in the house, there was dust on the floor, but there were no footprints, and the fingerprints had been fixed, but it was likely that all that could be found were the fingerprints of the deceased himself.

Judging from the scene, it is likely that it was just an accident" "Accident" Yan Sixian turned to Mink Fang and said, "Let's talk about the cause of death." ” "When I first investigated the scene, I found that although the body was highly decomposed, some of the skin could still be seen to be pink, and it was inferred that it was a suffocation death caused by carbon monoxide poisoning," Mink Fang said.
Autopsy tests showed that the concentration of Hb in the blood was greater than 50, which is higher than the lethal concentration.
The initial inference was verified that the cause of death was indeed carbon monoxide poisoning.
As for the time of death, it is estimated that 30 to 33 days have passed since death, and I can only accurately put the time of death to 72 hours.
There were no injuries on the surface of the body, and there were no signs of struggle or struggle before death.
The deceased's spleen ruptured and hemorrhaged, suspected to be caused by muscle spasms before dying after poisoning, although uncommon, has been seen in previous cases.
Vomiting is a normal reaction to carbon monoxide poisoning, and the vomit is inhaled backward into the trachea, causing the trachea to obstruct.
In general, from the autopsy, I am afraid that it is difficult to find the traces left by the murderer. ” Qu Yuan said: "There are no traces of the murderer in the trace examination and autopsy, this case should be an accident, and the district bureau is too much."
"The district bureau reported the case, and naturally there was a reason for reporting it."
Yan Sixian knocked on the table again and threw a photo in front of Qu Yuan, "This is a photo of the gas meter in the kitchen of the deceased's house."
The gas valve and gas meter were in the wall cabinet in the kitchen, and when the police arrived, the valve was closed, and the gas pipeline of the deceased's house was intact, there was no damage or leakage, and the gas stove was also closed normally.
The air leak alarm is in a daily state and there is no air leak reminder.
Where did the carbon monoxide that poisoned them come from?"
Qu Yuan opened his mouth and wanted to defend himself, but Yan Sixian didn't give him a chance, and continued: "There is also the problem of footprints you just mentioned, if you want to leave no footprints, it's very simple, just go into the house and change your slippers, in other words, acquaintances commit crimes."
Only acquaintances can enter the deceased's house unobtrusively, and even, not only enter, but also stay overnight, so they can secretly open the gas valve while the old man goes to bed.
After the old man died, the murderer closed the gas valve again, plugged the gas leakage alarm device that was specially unplugged from the power supply back into the power supply, reset everything, and then quietly left.
The reason why the murderer did this was probably to create the false impression that the old man who lived alone had died of some kind of sudden illness.
After all, there is such news every once in a while, and everyone is no longer surprised.
This explains exactly where carbon monoxide comes from.
It wasn't an accident, it was he who killed. ” Qu Yuan understood that he was inferior to Yan Sixian in terms of case analysis, so he didn't talk about the case, but said: "Even if he kills, shouldn't this case belong to the second team Zhao Ju said two days ago" The door of the conference room opened, and Wu Duan was bent over, wanting to sneak in, but he still attracted everyone's attention.
He sneered, straightened up, and walked towards the vacant seat beside Yan Sixian, and said, "You go on." ” Everyone was able to rest because of Wu Duan's light, and seeing that Wu Duan was injured and came to pay attention to the case, Qu Yuan was discouraged.
He pursed his lips in disbelief, meaning that there was nothing more to say.
Yan Sixian didn't relent: "You go on." ” Qu Yuan's face became not very good-looking, and the few people who were as dissatisfied as him exchanged glances to each other, and one of them boldly said in a loud voice: "Team Yan, Yuan'er doesn't mean that, if there is a case, we will handle it, and we have no opinion." ” Yan Sixian continued to be silent, Qu Yuan first twisted twice in the chair uneasily, as if silently cheering himself up, he raised his head and looked directly at Yan Sixian.
But for just a moment, Yan Sixian's appearance of not being angry and arrogant, and his contemptuous look of "I have seen through you" made Qu Yuan bow his head and avoid his gaze.
At this time, Yan Sixian spoke: "What kind of place is the team, everyone knows that the assistant police have holidays, and the household registration window also has holidays, and if you want to take a vacation, you can report and transfer now." ” After a pause, Yan Sixian asked, "Is there a report?"
This was the first time Yan Sixian got angry.
When he gets angry, he doesn't look angry at all, but surprisingly calm, as if he is on a card table, unhurriedly playing the cards in his hand, and every step is just so that the opponent has no cards to take.
After waiting for a while, Yan Sixian continued: "No, it's okay, then next time, if you ignore the suspicions, insist on saying that the murder is an accident, and prepare to report to the grassroots police station." ” When he said this, his expression was cold and harsh, and no one would not take his words seriously.
After saying this, his attitude immediately softened, as if nothing had happened just now.
He said to Feng Xiaoxiang: "Didn't Xiaoxiao also find something suspicious." ” Feng Xiaoxiang's face was always expressionless, even when the air was extremely solemn just now, she was just staring at her computer screen. was named by Yan Sixian, she first pushed the two photos to the middle of the table.
There were two close-up photos, one of which was a trash can with some food bags in it, and the other was a photo of the food bag taken out of the trash can and fixed separately.
A cream biscuit bag, a jelly bag, a bite of the jelly, some jelly boxes, the reason why there is a small amount of sugar left in the jelly box, there is already moldy hair in it.
"The garbage can next to the bed in the bedroom where the deceased was, the packaging bag of high-sugar food."
Feng Xiaoxiang stated simply.
She then showed a medical record through a projection.
Medical records of the deceased.
The examination indicators on the medical record clearly pointed out that the deceased's blood sugar exceeded the normal standard by several times, which was a relatively serious form of diabetes and was being controlled with medication.
Feng Xiaoxiang continued: "I checked the deceased's medical records in recent years and found that she had been taking hypoglycemic drugs and was an old patient.
Those things are too high in sugar for diabetics to touch.
It is no exaggeration to say that a single bite can cause a spike in blood sugar, which can lead to very serious consequences.
These sweets should not be in the home of the deceased who lived alone, unless they were taken out by the deceased to entertain guests.
But if it's entertaining guests, why do these bags end up in the trash can in the bedroom?"
Yan Sixian asked, "That trash can, could it be taken from the living room or dining room?"
A criminal police officer who participated in the on-site investigation answered: "No, the trash cans in the living room and dining room are where they should be, and judging from the remaining garbage inside, the trash cans have not been replaced."
For example, there are some dried fruit shells in the trash can in the living room, which corresponds to the dried fruit category in the fruit bowl on the coffee table.

In the trash can of the restaurant, there are some oil-stained napkins, which should be used by the host after the meal.
The trash can in the master bedroom was full of hair and nails, and we found a nail clipper under the pillow of the deceased, who must have been used to sitting on the bed and cutting her nails. ” "Understood," Yan Sixian cast an approving glance at the criminal police officer who answered the question, such a detailed observation is indeed worthy of praise.
Feng Xiaoxiang continued: "In addition, there is another doubt.
Whether these snack packages are eaten by the deceased himself or used to greet guests, don't you think these things are too young I'm not talking about the biscuits and jelly itself, of course, adults can eat these things, but the packaging alone is not very formal, especially the cream biscuits, which are not sold in the supermarket, but more like the low-quality snacks sold in the commissaries around the school.
Anyway, my first reaction when I saw these packages was: the victim had two grandchildren in his family.
But I checked the deceased's relatives and found that she had no grandchildren. ”:
