When Xu Lang and Ning Yanran came to the door of 603, Zhu Xumei was squatting in the corner of the door, retching, while Guo Jun was standing behind her, holding a bottle of mineral water in one hand and gently patting Zhu Xumei's back with the other.

Ning Yanran frowned a little unhappily when she saw this scene, she just wanted to walk over and reprimand Zhu Xumei for a few words, but was stopped by Xu Lang.

"What are you doing?"

"She is a criminal policeman, and she has to go in and out of the murder scene often, now that's it, what will she do in the future?" After Ning Yanran was stopped by Xu Lang, she became more and more displeased.

Xu Lang looked at Ning Yanran with a smile, shook his head helplessly, and said: "After all, she is a college student who has just graduated from the police academy, and she is still in the internship, facing the murder scene, it takes time, didn't you come here step by step back then?" ”

Hearing Xu Lang say this, Ning Yanran was suddenly dumbfounded, she knew that Xu Lang didn't say it too plainly, back then, when she saw the murder scene for the first time, she was worse than Zhu Xumei, and almost vomited on the spot, later, because of that incident, she had a nightmare for a long time, every time she dreamed, she could dream of the corpse in the scene, that time, Ning Yanran was very impressed, maybe from that time, Ning Yanran was a little afraid of the corpse, but now, it's okay, Ning Yanran is used to looking at corpses, and is used to going in and out of the scene of the murder, although she can't be like Ye Xuefei, she can eat food in front of the disemboweled corpse in the disembowelment room, but it is much better than before.

Xu Lang ignored Ning Yanran, he walked straight to the door, asked for a pair of gloves and shoe covers from Hu Anyun's hand to put on, and walked into the scene, since he came, he would definitely go to see the scene of the murder.

From the outside, although the house in the community is a little old, Tan Boheng's home is still very antique, giving people a feeling of being a scholarly family.

Xu Lang walked in from the door, and the first thing he saw was the people who were busy in the living room, forensic doctor Ye Xuefei and her assistant were conducting an autopsy on a body lying on the sofa, but Li Lei was not in the living room.

Xu Lang stood at the door, he didn't go in immediately, but looked at the door first, to be precise, to see if the door lock had been pried, Xu Lang observed it and found that the door lock didn't seem to be pried, Xu Lang had no expression.

On the left side of the door is a shoe cabinet, in the shoe cabinet are the shoes worn by Tan Boheng's family, the shoe cabinet is made of wood, it looks a little old, Xu Lang glanced at it, and walked straight to the living room.

The living room is not very big, there are three large and three small sofas, the sofa is covered with white lace sofa covers, among them, on the sofa in the middle lies a female corpse, the corpse lies on the sofa, the upper body is on the sofa, the lower body is on the edge of the sofa, the other leg falls to the ground, the female corpse is an old woman with gray hair, the old woman's cloudy eyes are wide, her mouth is slightly open, as if she wants to shout something before she dies, and there is a sharp knife in the old woman's chest, The entire blade of the sharp knife was inserted into the body, leaving only one hilt outside, and the white couch cover was stained red with splattered blood.

Xu Lang saw that Ye Xuefei was conducting a preliminary autopsy on the corpse, so he didn't go over, but found that a sign marked with the number one was placed next to the corpse, which was at the scene of the murder, when many bodies of the deceased were found, in order to meet the needs of the case, the corpses were numbered.

There was some noise in the living room, Xu Lang noticed it when he came in, he turned his head and saw a TV set placed opposite the corpse, and the TV was still playing a TV series, it was obvious that the first corpse should have been watching TV before it was killed.

There is an antique coffee table between the sofa and the TV, in addition to a few fruit bowls with apples and oranges on the coffee table, there are also a lot of books, some of these books Xu Lang has read, some Xu Lang has heard of them, these things are very thick, Xu Lang did not touch these corpses.

After He Liangping, a police officer of the Second Criminal Investigation Team, saw Xu Lang come in, he walked to Xu Lang's side and said: "Only one body was found in the living room, the deceased was a woman, probably in her sixties, and it should be Fan Ziyao, the wife of Tan Boheng, the head of the household. ”

"What about the bodies of the other victims?" Xu Lang asked.

"The body of the head of the household, Tan Boheng, is in the study, the body of his son Tan Shihao is in the bedroom, the body of his daughter-in-law Liu Yun is in the kitchen, and the body of the little girl Tan Jingjing is in her small bedroom."

"Take me to see it."

Xu Lang said as he walked straight to the outside of the study.

The door is open, Li Lei is inside at the moment, there is a staff member taking pictures in the room with a camera, after Xu Lang came in, he saw an old man with gorgeous hair, sitting on the chair behind the desk, the old man was lying on the desk, one hand was placed straight on the desk, the other hand was hanging under the desk, and a very old-fashioned computer was placed on the desk, in addition, there were a lot of books as thick as bricks, on the right side of the desk, there was a cup turned on its side, and the brown liquid in the cup flowed on the desk, The liquid soaked the books on the desk.

Xu Lang walked to the desk and took a closer look, and found that the old man had no external injuries on his body, black and red blood flowed from the old man's mouth, and the old man's face was blue.

After Xu Lang made this inference, his eyes subconsciously noticed the cup on the table and the liquid on the table.

After Li Lei saw Xu Lang come in, he found that Xu Lang was looking at the cup, and he immediately said: "After taking pictures, I will have someone take it back and hand it over to the technical department for poison analysis." ”

Xu Lang nodded and didn't say anything.

He looked up, no longer looking at the second corpse, but looked around and began to look at the study.

The study room is very large, except for the wall with windows, the remaining three walls are placed with bookcases, in the bookcases opposite the desk and on the side face, there are a lot of books in different categories, and the books are placed neatly, and in the bookcase behind the desk, in addition to the books at the bottom, the top of the bookcase is full of various trophies, awards and honorary certificates, which should be the honors that Tan Boheng's family has won in their lives.

Seeing those objects standing quietly on the bookcase, Xu Lang couldn't help but show a look of admiration, these things that seem worthless, I don't know how many people want to take things in their lives but can't get them.

"Professor Tan's family are all teachers and have won countless honors, which is really admirable." Li Lei said on the side.

Xu Lang didn't have any change in expression, he walked out of the study after looking around the study, and Li Lei left the study with Xu Lang.

Outside the study, Xu Lang met Ning Yanran, and Ning Yanran asked, "Do you see anything?" ”

Xu Lang shook his head and said, "Let's talk about it after all the corpses are finished." ”

After saying this, Xu Lang came to Tan Shihao's bedroom under the leadership of Li Lei, the layout of the bedroom is very simple, in addition to placing a large wardrobe and a double bed in the room, a desk is also placed by the window, and a lot of books are also stacked on the desk, and a man is lying on the desk, looking similar to the appearance of the second corpse.

Li Lei explained: "This is the No. 3 corpse, the deceased is Tan Shihao, 45 years old this year, a teacher in our city's No. 32 Middle School. ”

Xu Lang walked to the desk, looked at the corpse carefully, and found that the corners of the corpse's mouth also flowed black and red blood, and his face was also purple and blue, which should have been poisoned to death, under the deceased's cheek, there was an open high school Chinese textbook, and there was a black notebook next to the textbook, the notebook was densely filled with handwriting, it should be a lesson plan, the deceased put one hand on his lap, and one hand was still holding a fountain pen, and the ink of the fountain pen dripped on the lesson plan, and a large black spot appeared, Near the black dot was the blood stains on the paper, and on the left hand of the corpse, there was a teacup, the tea in the teacup had bottomed out, obviously, the deceased should have drunk the tea in the cup before he died.

Xu Lang looked around the bedroom again, and found nothing unusual, so he walked out of the bedroom and came to a small bedroom in the innermost.

Compared with Tan Shihao's bedroom, the small bedroom is very warm and cute, of course, this is only relative to Tan Shihao's bedroom, compared to the bedroom of most seven or eight-year-old girls, Tan Jingjing's bedroom is a little simple and monotonous, in addition to a single bed in the room, there is also a desk, on the desk put a lot of primary school textbooks, and a table lamp, the table lamp is pink, the shape is a robot cat, it looks cute.

The fifth corpse, the little girl Tan Jingjing was lying quietly on the single bed, the little girl was wearing a pink one-piece pajamas, the quilt printed with the bear on the bed fell to the ground, the little girl was lying on her back on the bed, the skirt of the pajamas was lifted and covered the girl's face, revealing the little girl's thin legs and white bottoms.

Xu Lang walked to the side of the bed, looked at it carefully, and then turned his head to look at Li Lei, casting an inquiring look.

Li Lei knew what Xu Lang wanted to ask, and he hurriedly said, "I've already taken pictures." ”

Hearing Li Lei say this, Xu Lang stretched out his hand and put down the skirt on the girl's face, revealing the girl's red and purple face, and the girl's neck was wrapped around a pink thing similar to a towel, Xu Lang took a closer look and found that this was not a towel, but a pillow towel, the little girl's hands were clutched on the pillow towel, her eyes were wide open, and her eyes were full of fear and pleading.

"It was strangled to death." Xu Lang said slowly.

Li Lei and Ning Yanran both saw this scene, and naturally saw it, they nodded, their faces were very ugly, anyone who saw the corpse of such a young child would not be in a good mood, especially not long after the series of cases in the orphanage, everyone had not come out of the psychological shadow of the death of that group of orphans, and now they saw the corpses of children, it would be strange if their mood could be good.

Xu Lang and the three of them didn't want to stay in this innocent-looking room anymore, so they walked out of the smallest bedroom and went to the kitchen instead.

When Xu Lang came to the kitchen, the corpse of a middle-aged woman wearing home clothes was lying on the cold floor, on the white floor, there was a large pool of blood, the deceased showed a crawling posture forward, one hand stretched straight to the door, one hand next to the head, the kitchen also exuded the fragrance of rice being cooked, the fragrance of rice and the smell of blood were mixed together, making people smell indescribably disgusting.

"This is the No. 4 corpse, the deceased's name is Liu Yun, forty-two years old this year, and he is a teacher at the Experimental Middle School in S City." Li Lei explained on the side.

Xu Lang didn't listen to what Li Lei said again, he squatted down and looked at Liu Yun's right hand carefully.

Liu Yun's right hand stretched straight to the door, this is nothing unusual, what caught Xu Lang's attention is that on the back of Liu Yun's right hand, there are traces of being trampled on, and the five fingers have been trampled on a little twisted and deformed, in addition, the deceased's hair has been torn by people, and on the ground next to the deceased, a lot of broken hair has also fallen, in addition, Xu Lang also found that on the back of the deceased, the back of the waist, and the traces of being trampled on, leaving a vague shoe print, look at the size and pattern of the shoe print, It should be men's shoes, and the shoes should be slippers.

Compared with the previous four corpses, Xu Lang found that only Liu Yun should have suffered great torture and abuse before his death, which can be seen from the hair that the deceased fell on the ground, the shoe prints on his body, and the twisted and deformed fingers.

Xu Lang frowned, feeling a little strange, Tan Boheng and Tan Shihao were both poisoned, while Fan Ziyao was killed by a sharp weapon stabbed into the heart, and the little girl Tan Jingjing was strangled by a pillow, whether they were before or after death, they were not tortured and abused by the murderer, but Liu Yun's body was tortured and abused, which is a little strange.

Xu Lang didn't know if Liu Yun's body had been photographed, so he didn't move the body, but stood up and looked at Li Lei.

Li Lei has been following Xu Lang for a day or two, with one look and one action, he knows what Xu Lang wants to do, so Li Lei said: "The No. 4 corpse was stabbed in the chest from the front, and a knife directly pierced the heart, and died of excessive blood loss. ”

Xu Lang groaned, walked out of the kitchen, and asked, "Have you found the murder weapon?" ”

Li Lei glanced at Xu Lang, then looked at the location of the No. 1 corpse in the living room, and said: "The only murder weapon found at the scene was the sharp knife on the chest of the No. 1 corpse, it was a boning knife, we checked the kitchen and found that there was a knife missing in the kitchen, and the boning knife should be the original knife in the kitchen." ”

"It's a local source." Xu Lang muttered to himself.

"Did you get any fingerprints on the hilt?" Xu Lang continued to ask.

"Yes, several fingerprints have been collected, and as for whether there are any left by the murderer, we still need to wait for the comrades of the technical department to compare before we can know."

"Doors and windows checked?"

"It's all checked, the door, there are no traces of being prying, and there are no traces of the windows being pried, this is the sixth floor, because this community has been robbed before, so the balcony of every house has been equipped with anti-theft nets, under normal circumstances, there is no way to enter from the balcony."

After listening to Li Lei's introduction, Xu Lang pondered for a moment and said: "The five deceased, except for the fourth deceased who was tortured and abused, the other four deceased were not tortured and abused, they were all doing their own things before they died, and the murderer should be someone who is very familiar with this family, this is an acquaintance who committed a crime." ”

Li Lei nodded, he was the first to arrive at the scene, and he was also the first person to investigate the scene, after he surveyed the scene, he came to the same conclusion as Xu Lang, in the case of intact doors and windows, and no fight at home, a family of five was killed, which was obviously committed by acquaintances.

Ning Yanran opened her mouth at this time and asked, "What about the informant?" Where are the others now? ”

"Oh, the informant has been brought back to the team, and he's taking notes."

When Li Lei said this, he looked at Ning Yanran, thought for a while, and asked, "Team Ning, do you suspect that the informant committed the crime?" ”

Ning Yanran neither nodded nor shook her head, obviously, she did have such a guess, after all, the door of 603 was not closed, and the informant happened to appear at the scene, although in the past, when handling cases, the police often did not suspect the informant at the first time, but as Ning Yanran solved more and more cases, she began to become the same as Xu Lang, before the case was solved, she maintained a suspicious attitude towards all those who had a relationship with the victim and were familiar with it.

Xu Lang looked at Ye Xuefei, who was still busy in the living room, and he asked, "What is the name of the survivors of this family?" ”

"Tan Wenrui." Li Lei said.

"Yes, it's Tan Wenrui, did you tell him about the situation here?" Xu Lang asked.

Li Lei glanced at Ning Yanran, shook his head, and said, "I have already notified the school and asked the school's teachers to bring Tan Wenrui to the team, it is estimated that he is in the team now." ”

"What time did the crime happen?"

"Nine o'clock in the morning."

"Nine?" Xu Lang raised his wrist and looked at the watch on his wrist, it was now eleven o'clock in the afternoon, and nearly three hours had passed.

Xu Lang frowned and asked, "What day of the week is today?" ”

"Sunday." Li Lei looked at Xu Lang puzzled.

"Isn't school closed on the weekend? Why didn't Tan Wenrui go home? Xu Lang asked with a frown.

"Oh, that's right, Tan Wenrui is a sophomore in high school this year, his academic performance has always been very good, he is the top student in the class, especially in mathematics, recently, their school is going to hold a learning competition, Tan Wenrui is one of the contestants, the competition is about to start in a week, for a better competition, he has not been home for two consecutive weeks." Li Lei explained.

"So, Tan Wenrui was at school at the time of the crime, right?"

"That's right."

"Who can prove that?" Xu Lang looked at Li Lei and asked.

"This"

Li Lei looked at Xu Lang and then at Ning Yanran, and he didn't know what to say for a while.
