Wei Chenwan sent a message to Lin Xi after class, because she had to have dinner with her colleagues in the evening, but Lin Xi didn't return after a long time, because Lin Xi was on her way to handle the case at this time.

At four o'clock, the office phone rang, and the phone rang at this point was the most worrying, Lin Xi listened to the phone and got up to take his coat.

The crowd got up and went about their business.

After arriving at the old building of the resident's house, I saw a little girl beside the police at the scene, still looking like a student, without any expression on her face, just like Wei Chenwan who encountered something back then.

Lin Xi looked over, and the little girl's eyes kept staring at him.

"Hello Team Lin. "The police came over.

"What's the situation, it's a homicide?"

"The situation at the scene is unknown, but the daughter of the family asked a neighbor to call. ”

Lin Xi walked into the cordon.

"Why did you ask your neighbor to call?"

The police replied: "The little girl went out to watch a movie with her classmates, and when she came home, she found that her family was sitting on the sofa and did not move, but the TV was on. ”

Lin Xi nodded and went to the neighbor next door to ask questions.

"Hello Auntie, let me ask about the situation of this family. ”

The neighbor next door began to speak as soon as he inserted his hands: "It's not me who said anything, this family deserves to die, and people are watching the sky, tsk." ”

"Auntie, what do you say?"

"This family is weird, our neighbors are famous for their strangeness, especially bad for this adopted daughter, you said that you finally brought a daughter back, they didn't take long to ignore it, sometimes they drank too much and beat people, it was also funny, not long after Lulu was brought back, Lao Jiang's wife was pregnant, but it seems that there was a miscarriage later, after a year, Lao Jiang's wife was pregnant again, and now she finally had a son. ”

"You said that little girl is an adopted daughter?"

"Yes, Lulu was picked up from the orphanage three years ago. ”

"Did you hear anything this afternoon?"

"No, they just went out to buy groceries in the morning and went home, nothing else. ”

"Has anyone ever been in or out of their house?"

"Then I don't know, what kind of dealings can their family have with others, who wants to go to their house?"

"Let me ask if there are any enemies in this family?"

"Oh, this can't be said, what is playing cards outside and not giving money, buying things on credit, and often quarreling with others, if you want to say that there are enemies, then they have a lot of enemies. ”

The aunt interjected and chattered a lot, and Lin Xi almost couldn't interrupt what she wanted to say, and she understood what the family was like from the mouths of the neighbors.

Lin Xi turned around and shouted, "Sister Ai, are you done here?"

Armand asked the little girl some questions from a distance.

"It's over. ”

Armand put away his voice recorder and notebook, and touched the little girl's head.

Lin Xi blinked his eyes and found that the little girl was still looking at him, Lin Xi didn't care, just exchanged opinions with Aimang.

"Sister Ai, the problem now is that the family has passed away now, and this little girl has become an orphan again, she was originally brought in from the orphanage, and now she is only 15 years old and a minor. ”

"Let's take it back to our bureau first, and then we'll see what we do. ”

"Okay. ”

Just when Lin Xi was about to enter the room to find Gao Jun, suddenly there was an exclamation behind him, and the little girl fainted directly to the ground.

The surrounding police assisted in taking the person to the hospital.

After working outside for a while, Lin Xi walked into the deceased's home.

Gao Jun had already put some things into the evidence bag.

Liu Changmin examined the body on the side, then walked around the house and found an empty bottle of medicine.

Lin Xi walked over to see the words on the medicine bottle and said, "......What is the nature of this case?"

Liu Changmin shook his head: "I don't know, I won't know until I go back for an autopsy." ”

The car outside came to pull the body back, Liu Changmin followed him, and Lin Xi followed Gao Jun to search the house inside and out, and also found the adoption certificate in the closet.

When the things in the room were almost found, I closed the team and went back.

When I arrived at the Public Security Bureau, I remembered to send a message to Wei Chenwan.

Lin Xi took out his mobile phone and saw the message, which was more than two hours ago.

Wei Chenwan and her colleagues finished eating early, went back early, and walked around home, but Lin Xi was not at home.

Could it be that there is another case?

She was just about to take out her mobile phone to call Lin Xi when she saw Lin Xi's phone calling.

"Hey Lin Xi, do you have a case?"

"Well, I was about to tell you. ”

"Then I'll come over now. ”

"No, no, you have a good rest, I'll go home at night, you can come back tomorrow." ”

"Is it really okay?"

"It doesn't matter, the door is locked at home alone, and I don't have to leave the door for me if I bring the key myself. ”

"Good. ”

Lin Xi and Wei Chenwan finished the phone call and went to the forensic office to find Liu Changmin, because there were three dead this time, so Liu Changmin found the forensic doctor to assist him.

Faced with a child more than a year old among the deceased, Liu Changmin almost couldn't do it.

"Lao Liu, how is it?"

"It's going to take some time, I'm going to get something tested. ”

Lin Xi went to other forensic doctors to ask about something.

"The deceased is a woman and two men, it is a parent-child relationship, there are no external injuries on the body, there is no fighting, there is no wound on the body, there is no excessive blood loss, followed by the cause of their death, Forensic Doctor Liu and we have the same opinion, at first I thought it was an overdose of sleeping pills, and there were indeed sleeping pill ingredients, but another manifestation inside the body was poisoning, so he now went to test the poisoning components in the blood. ”

"Poisoned?"

"Yes, there is discoloration on the fingertips, an abnormal color reaction under the skin. ”

As he was talking, Liu Changmin walked over, holding a table in his hand, on which was the comparison of special substances in the blood, and the closest substance in the first row was aromatic phenoxypropionic acid.

"Lao Liu, what is this?"

"The most common occurrence of this ingredient is herbicides, so it's likely that they're poisoned by herbicides, and the same substance was detected in the meals they had in the refrigerator. ”

"If it's just too much sleeping pills, I'll judge it as suicidal, but if it's herbicide poisoning, will it be homicide?"

"It's possible, but it can't be ruled out that it was ingested by mistake. ”

Lin Xi touched his chin and said, "Do they have a lot of aromatic phenoxypropionic acid in their bodies? If they eat it by mistake, it shouldn't be too much." ”

"Even a small amount of aryloxyphenocypionic acid can kill if left untreated. ”

He suddenly thought of sleeping pills, because the neighbor said that the Jiang family was not different from usual, if it was poisoned by accidentally ingesting herbicides, there should always be a call for help, and besides, there was still their one-year-old son at home, and the parents should also have the heart to save the child.

Lin Xi muttered in his mouth: "Sleeping pills and herbicides, even a small amount, are difficult to treat in time. ”

"You're right, I'll bring you our report in a moment. ”

Everyone sorted out the existing materials at hand in the office, and after Lin Xi returned to the office and sat down, Liu Changmin took the report.

While waiting for the report, I also received a call from the hospital police, and the doctor said that Jiang Lulu only fainted due to excessive mental pressure, and there was no major problem, mainly because she needed to recuperate for the past two days, and she woke up for a while just now, and she fell asleep again without eating.

Lin Xi said that he knew and asked the police to continue to help take care of Jiang Lulu.

He hung up the phone and sighed, she was already an orphaned little girl, and she finally found someone but didn't treat her well, so she was adopted for three years, and her adoptive parents had an accident again, should I say that she was miserable or unlucky.

Lin Xi flipped through the time report to learn some details that he didn't know yet.

In terms of the time of death, I saw that Liu Changmin's forensic judgment was extrapolated backwards from the time when the food remained in the deceased's stomach, basically not long after today's lunch, and it was speculated that it was around one o'clock in the afternoon today according to the temperature of the corpse.

One o'clock in the afternoon?

Lin Xi made a phone call to the forensic office.

"Lao Liu, are you sure about the time of the deceased's death?"

Of course, it is not difficult to calculate the time of death by this method of death. ”

The call confirmed the time of the deceased's death, and Lin Xi found Aimang to give him a testimony from Jiang Lulu, saying that she went out to watch a movie with her classmates in the afternoon, and when she came back, she found that no one in her family had responded.

Lin Xi glanced at his watch, it was almost nine o'clock, so he hurriedly called everyone for a meeting, and let people go back first when it was finished, and some things will be talked about tomorrow.

Several people gathered in the conference room to discuss their own statements.

"Ladies and gentlemen, the main problem now is that I can't determine the nature of this case, I can't tell whether the death of the Jiang family was suicide or homicide, if it was just accidental ingestion and poisoning, I can close the case now, but if it was killed by him......"

Lin Xi didn't say any more, everyone knew what to do later if it was a murder case.

He raised the autopsy report in his hand and said: "This is the autopsy report given to me by Lao Liu, the time of death was around one o'clock in the afternoon, I have seen the evidence, Jiang Lulu's movie ticket is two o'clock in the afternoon, the movie theater is half an hour away from her house, it is equivalent to their family having lunch, Jiang Lulu went to see a movie, the Jiang family was poisoned and died, Jiang Lulu went home and found that her family was abnormal, so why is Jiang Lulu okay?"

Ai Mang thought for a while and said, "Because the Jiang family treats her badly, they won't eat with her, which caused Jiang Lulu not to eat herbicides by mistake." ”

"In addition to herbicides, there is also a drug here is sleeping pills, sleeping pills are very strange on this occasion, why take sleeping pills at this time period, I put forward two hypotheses, if they want to kill themselves, herbicides alone can be solved, herbicides are very fast, if they want to kill themselves with sleeping pills, then what is the effect of herbicides. ”

Someone said, "Maybe it was because the sleeping pills didn't work well, so I took herbicides again." ”

Lin Xi shook his head: "If that's the case, why put herbicides in the meal?"

Someone else said, "Maybe it's self-produced and self-sold! I can't tell my family, so I put it in the food." ”

Lin Xi took out the testimony of his neighbors and circulated it to everyone.

"The temper of the Jiang couple is very strange, but they came to have a son late, and they finally had a son, so they may not be able to guess this attitude towards the adopted daughter, but it is such a family, what kind of attitude do they want to commit suicide?"

The room fell silent.

Lin Xi stood in the middle of the conference room, propped up the table with both hands and said, "The suicide is contrary to the reality of their lives, some people are lying, but we have no substantial evidence now." ”

The most annoying thing about this kind of case is that there is no substantial evidence to prove that it was a homicide.

Lin Xi didn't let people linger here for too long, it was already night, and the work efficiency was not high.

"Everyone go back tonight and think about whether there are any contradictions in this case, the other thing is that Jiang Lulu has now become an orphan again, and she is a minor, we had better help her think of a way, maybe tomorrow we have to contact her previous orphanage. ”

The crowd nodded and the meeting discontinued.

Lin Xi planned all the work to be done the next day and put it in the work group, and then rushed them to get off work.

When he got home, Wei Chenwan was already lying on the bed and scrolling Weibo.

Lin Xi walked into the bedroom, and Wei Chenwan lay on the bed and looked up at him.

"How's the case going?"

"It's a bit troublesome, it's a test of our ability to collect evidence, do you want to go to the bureau early with me tomorrow?"

Wei Chenwan turned over and replied, "Okay." ”

Lin Xi lowered his body and kissed her on the forehead: "I'll go take a bath first." ”

"There is a late night snack in the kitchen for you. ”

"Thank you baby. ”

Lin Xi came out of the shower and walked directly to the kitchen, and in the incubator turned out to be pasta, which was quite high in calories, but today's case and meeting have exhausted brain cells, so it's time to replenish some calories.

After eating, Lin Xi instantly felt that his spirit was up.

After washing up and returning to the bedroom, Wei Chenwan was tapping on her mobile phone, Lin Xi lifted the corner of the quilt and saw that she had changed into a new set of pajamas, and the clothes were short.

"What are you doing?"

"Play Sudoku. ”

As soon as Lin Xi slept on the bed, Wei Chenwan leaned over looking for a heat source, the hem of his short clothes shrunk to his stomach, and the smooth skin rubbed against his arm.

Wei Chenwan turned off the hardmode Sudoku before she finished playing, turned over and hugged Lin Xi.

"What do you think is the difficulty in this case?"

Suddenly asking such a serious question?

"We can't tell if the family committed suicide or homicide, and according to the logical analysis, we killed him, but we can't find any key evidence. ”

"Do you have any clues?"

"It's all my guess, I'm going to check it tomorrow, I suspect it's not that simple. ”

"Then I'll think about it more tomorrow and try to draw it as soon as possible. ”

Lin Xi touched her face and said, "It's a big night, I finally got off work, but you were talking about business at home." ”

Wei Chenwan stuck out her tongue.

"I won't say anything. ”

Lin Xi hugged her all over herself, and Wei Chenwan found that he really liked this position, and she put her head on his chest.

"Wan'er, don't tease me. ”

"I didn't tease you, I didn't move, don't sue the wicked first. ”

Lin Xi smiled very badly, every time as long as there is a case to be handled, they will always be very tacitly abstinent and must not affect their work, so in today's situation, Wei Chenwan will definitely not make unnecessary actions, but Lin Xi depends on her for some reactions.
