"Ahh Lin Shu, who was once again awakened by that repeated dream, looked at the familiar classroom around him in horror, as well as the group of classmates who were frightened by him, and his heartbeat gradually returned to calm.

"Freak, what the hell are you calling again? Who are you trying to scare to death? A strong arm slapped Lin Shu's back.

Lin Shu slowly turned his head and stared at the man in front of him without speaking. This man's name is Ma Dongsheng, and he grew up in a small area with Lin Shu, but the relationship has never been harmonious.

Ma Dongsheng looked at Lin Shu's eyes staring at him without a trace of fear, but said with rage: "What's the matter, are you going to kill me like your father killed your mother?" After speaking, he didn't forget to pat his chest, "Here, poke here." ”

Lin Shu loosened his clenched fist, ignored Ma Dongsheng's provocation, turned around and left through the back door.

In the toilet, looking at the washed face in the mirror, Lin Shu really couldn't figure out why 17 years had passed, and the events of that year would still appear in his mind. It's not that he hasn't tried to tell the police who handled the case about the figure that appeared in the fire, but no matter how the police investigate and visit, there is no evidence to prove that this person existed in the fire.

"If that clip was my imagination, then why is it so real, and what does the tattoo on that person's arm represent?" Looking at himself in the mirror, Lin Shu shook his head helplessly and left.

That night, Lin Shu, who was struggling for the graduate school entrance examination in the library, suddenly felt a wave of sleepiness coming, and gradually he closed his eyes.

It was that familiar sea of fire again, and even the temperature of the flame's hot breath hitting his face was exactly the same, such a scene Lin Shu had experienced many times. But this time there seemed to be a slight difference, Lin Shu tried to move his body, and found that there was no previous sense of powerlessness. Although it was still very difficult, he still held on to the wall and tried to keep himself going, although the hot wall had burned his hands to the point of blistering, Lin Shu didn't care. This time, he wanted to uncover the true identity of the figure with his own hands, and uncover the nightmare that had plagued him for years. Walking like this, I don't know when there was no fire at the end of the sea of fire, but the figure never appeared. Maybe it was too long to walk on the fire, and this body struggled to even stand, and Lin Shu tried to hold on to it with a big pant, trying to hold on until the person appeared. But after a while, Lin Shu felt that his consciousness was gradually blurred, and something seemed to flash in front of him, but soon he passed out...

When Lin Shu woke up, it was already slightly bright, something seemed to be happening outside, and he felt unusually noisy, he shook his head to keep himself awake, and packed up his things and moved towards the noise.

The crowd gathered in front of the old activity building, which is usually used to store sundries, and several police cars were seen at the scene. Lin Shu squeezed in and saw the cordon, and the white cloth under the tree that was spread on the ground to cover something, and the traces of blood oozing from it.

The order of the scene is not bad, much calmer than expected. In front of the activity building, a circle of warning tape was pulled indiscriminately, and some students were standing sparsely around. There was nothing in the middle of the cordon, except for a white cloth, and I really didn't know what these students were watching. There is a small pool of blood underneath the white cloth, and a small amount of splattered blood can be seen around the pool of blood. The trace-checking person took out the investigation box, took a part of the blood pool and the splattered bloodstains, recovered the objects at the scene, and quickly transported the body away after taking pictures.

Lin Shu looked at it for a while and then planned to go back to the hut he rented and continue to catch up on sleep, after all, last night's dream made him feel as if he had really walked in the fire.

Two

I don't know how long it took, but I vaguely heard someone knocking on the door, and Lin Shu got up in a daze.

The sound of a "bang-bang" sounded again outside the door. "Is Lin Shu here?" The visitor asked.

Lin Shu opened the door and saw two policemen, one old and one young, "I'm Lin Shu, what are you looking for me?" ”

"There are some things that require you to cooperate with our investigation, so please come with us." Among them, the policeman who looked older showed his police ID and said to Lin Shu.

Lin Shu looked at the policeman who said Liu Jianshe on his police card, although he was a little puzzled, he nodded, then changed into a pair of dry short-sleeved civilian clothes, and followed the two policemen downstairs and got into the car.

It was an old-fashioned manual transmission police car, which looked to be many years old, and it was the policeman surnamed Liu who was driving, and the other younger one was sitting in the back seat with Lin Shu. Lin Shu didn't take a police car once, on the contrary, he used to take a police car a lot of times.

The young policeman probably thought that Lin Shu would be nervous, so he looked at him and said comfortingly: "You don't have to be nervous, my name is Zhang Dong, you can call me Brother Zhang, this time we mainly want to learn from you about Ma Dongsheng's situation." ”

Lin Shu thought of the events of the early morning, and then was surprised and said with a hint of doubt: "What's wrong with him?" Is it dead? Murder or suicide? ”

When Zhang Dong wanted to continue talking, Liu Jianshe suddenly coughed, "It's almost here, let's talk about it when something happens." ”

Soon the three of them came to the door of the Public Security Bureau of Anyang High-tech Zone, Zhang Dong got out of the car with Lin Shu, and Liu Jianshe went to park the car.

Zhang Dong led Lin Shu to the interrogation room, "You wait here, there will be a pre-interrogator to question you later." ”

It didn't take long for three investigators and interrogators to walk in the interrogation room, one of whom was still an acquaintance, Xu Rong, who had co-handled their family's murder case that year.

"I am today's chief judge, my name is Xing Xie, I am the deputy captain of the Criminal Investigation Brigade of Anyang High-tech Zone, and I am also the person in charge of Ma Dongsheng's murder case." The man who spoke was a man who looked to be in his thirties, with a Chinese face, thick eyebrows and big eyes.

"I'm today's assistant judge, my name is Xu Rong, just ask questions today, don't be nervous." Xu Rong is a middle-aged man with a kind face, and he has taken great care of Lin Shu since he lost his parents.

"I'm today's recorder, my name is Ning Xiaoxiao." A petite-looking female police officer turned on the video footage.

After Xing Xie nodded to Xu Rong to start, Xu Rong straightened up and said, "Lin Shu, 21 years old, a junior at the Faculty of Law of Anyang University, right?" ”

"Hmm."

"At about 5 o'clock this morning, we received a report that a male corpse was found in front of the old activity building of Anyang University, according to the objects on the body, it was preliminarily determined that the deceased was Ma Dongsheng of your school, according to the visit and investigation, at about 11 o'clock last night, someone last saw the deceased walking in the direction of the crime scene, what were you doing from 11 o'clock to 5 o'clock in the morning last night?"

"I stayed in the library around 10 o'clock last night, and then I fell asleep when I was tired of reading, and I didn't wake up until this morning." Lin Shu recalled, "If you need witnesses, there shouldn't be, after all, the library is basically empty, you won't suspect that I have something to do with Ma Dongsheng's death." ”

"It's just a routine question, and according to the results of our trace examination, Ma Dongsheng's death is likely not an accident or suicide." Xing Xie held his chin and said with a little meaning, "You have not provided a valid alibi now, and according to the interview, we have found that you have a major motive for committing the crime, and we have to suspect you." ”

"Motive for the crime?"

"Yes, Ma Dongsheng has known about your family since he was a child, and he has been counting you down and attacking you in front of and behind people, and there are eyewitnesses who confirmed that he made fun of your deceased parents yesterday, and it is possible for you to kill him in a fit of anger."

"You also know that I have known him since I was a child, and if I wanted to kill him, I would have killed him a long time ago, why do I have to kill him now." Lin Shu shrugged his shoulders a little helplessly.

Xing Xie looked at Lin Shu, as if he wanted to see a hint in his eyes, "I don't believe you, I only believe in evidence." He then left the interrogation room.

Xu Rong followed out, blocked in front of Xing Xie and said, "Team Xing, I watched this kid Lin Shu grow up since he was a child, he is not such a person, and he can't do such a thing." ”

At this time, Zhang Dong suddenly ran over and said: "Report to Team Xing, just now Xiao Xu has finished reading all the monitoring of yesterday's Anyang University Library, we can be sure that Lin Shu entered the library at 9:57, and then took the elevator all the way to the 3rd floor, and did not leave until 5:53 in the morning." At the same time, the men who checked the traces also investigated the scene, and the windows of the library were fenced, and there was no damage to the periphery, and there were no traces of climbing on the periphery. ”

After hearing this, Xu Rongtian said to Xing Xie with a smile on his face: "What about Xiaolin? ”

"Let it go, don't be embarrassed, I can't ask anything." Xing Xie waved his hand impatiently.

Not long after he went out, Xu Rong turned around and returned to the interrogation room and said to Lin Shu: "Let's go, Xiaolin, I haven't come to see you Uncle Rong very much lately, you are not allowed to go anywhere after work tonight, Uncle Rong will take you to dinner." ”

"Thank you, Uncle Rong, I've been busy with the graduate school entrance examination recently, but Uncle Rong called, I must be there tonight." Lin Shu scratched his head, probably feeling a little embarrassed that he hadn't come to visit Uncle Rong recently.

The two walked as they talked, and suddenly, Lin Shu, who was passing in front of Captain Xing, stopped, and he stared at a piece of evidence on Captain Xing's table, which should be a can of bloodstained Coke to be exact.

"Where did you find this?" Lin Shu asked suspiciously.

"Have you seen it? Where is it? Xing Xie stared at Lin Shu in front of him in some surprise, and after a while, he shook his head bitterly: "I'm really stupid, I actually think that you have really seen it, how can you be sure that this is the can of this kind of drink that can be seen everywhere." ”

Lin Shu frowned, trying to remember where he had seen this can of Coke, and suddenly his brow loosened, "No, I'm sure I've seen it." ”

Three

Xing Xie, who looked expectant, asked, "Where is it?" ”

"In a dream."

Xing Xie was so angry that he stood up on the spot, pointed at Lin Shu's nose and scolded, "You play Lao Tzu, don't you, Lao Tzu believes in your evil, you melon baby!" ”

As soon as Xu Rong saw that the situation was wrong, he hurriedly pushed Lin Shu away, and then pulled Captain Xing to the side and whispered: "Team Xing, this kid has been hit too hard since that incident, and he often sees some strange things. ”

Xing Xie looked at Lin Shu, smacked his lips, and said, "Okay, tell me what you saw, and if there is anything else." ”

Perhaps in order to figure out the connection between dreams and reality, Lin Shu bit his fingers and said: "Since I have ruled out suspicion, I apply to join the criminal investigation team as an intern to cooperate in handling the case, I want to know more detailed case information, which will help me sort out what I see." As he spoke, he opened a certain document on his phone and handed it to Team Xing.

Xing Xie glanced at the documents in his phone, then gave Lin Shu a thumbs up, then held back his anger, and said to Zhang Dong: "Xiao Zhang, you can run away, go and call Xiao Qi and Xiao Zhou over for the trace inspection, and let them make a case integration report by the way." ”

"Yes, Team Xing." Zhang Dong responded and ran out.

After a while, two girls who looked to be in their twenties and wearing police uniforms walked in with Zhang Dong, and after taking a look at everyone, they came to Xing Xie, "Captain of the Criminal Brigade, you are looking for us." ”

Xing Xie nodded and said, "You two will describe the discovery of Ma Dongsheng's murder in detail." ”

Among them, a tall and thin girl with a ponytail stood up first and said: "I'll come first, I'm Qi Xin from the Trace Examination Department, responsible for the physical evidence investigation and summary of the scene, about the case of Ma Dongsheng, we compared many bloodstains at the scene of the crime, and no DNA of anyone other than the deceased was found." Since the scene of the crime is an abandoned old activity building, which is basically used to store sundries, there are neither cameras nor special personnel to supervise them. Then Qi Xin walked to the whiteboard, pasted a photo, and pointed: "Through on-site investigation, we locked the scene of the crime on the rooftop on the fourth floor of the activity building, because here we found the key evidence of the case, that is, this can of Pepsi Cola stained with blood." ”

Lin Shu interrupted: "Is the blood on the cola Ma Dongsheng?" ”

Although Qi Xin was a little puzzled by the strange boy in front of him, he continued to say after seeing that everyone had no opinions: "Yes, the blood on it is all Ma Dongsheng's, but the blood concentration is very low, and it is diluted blood. In other words, it may be due to the doping of dew, or it may be caused by the condensation of the ice cola, and in general, this amount of bleeding is not fatal. There are several incomplete sets of fingerprints on the Coke, but there is no way to extract them effectively. No traces of a fight were found at the scene, and the above is the report of the Trace Examination Department, thank you. With that, she consciously stepped aside, leaving her place to another girl with short or medium hair.

"I am Zhou Yinglin from the forensic department, we performed an autopsy on the deceased, the following is my autopsy report, a male corpse, the corpse is 181cm long, there is no abnormality in development, good nutrition, the initial formation of mortis in the large joints, the face and chest and other falling surfaces appear cloud-like corpse spots, and the rest of the skin is pale, no yellow. Black hair. The cornea is mildly opaque, the pupils are equal to each other, the diameter is 0.8 cm, and the sclera is not yellow. A small amount of reddish blood came out of the mouth and nose cavity and bilateral ear canals, and there were bruising marks around the eyes. The trachea is centered, the thoracic cage is symmetrical, the abdominal cavity is not abnormal, and the limbs are not deformed. Multiple soft tissue injuries throughout the body, more subcutaneous hematomas, multiple fractures, visceral hemorrhage, systemic injuries should be formed at one time, consistent with the situation of high fall injuries. In addition, the bare skin of the deceased had multiple minor wounds, which were probably formed by the branches of the mango tree next to the movable building during the fall. ”

"And what about the exact time of death?" Xing Xie leaned back in the chair and raised Erlang's legs and asked.

"Because it is summer, the temperature difference between day and night is large, and the vegetation at the scene of the crime is vigorous, and the corpse is covered with a layer of dew, and the time of death cannot be accurately determined by the temperature of the corpse, I can only determine the degree of digestion of the stomach contents, the food residues in the stomach of the deceased have not been completely digested, and the time of death is about 2 to 4 hours after the last eating time."

Lin Shu silently approached the deceased's CT and looked at it carefully, "Okay, I can now confirm that the Coke I saw is this can, and in my dream I saw someone holding this can of Coke and smashing it on the back of Ma Dongsheng's head." Lin Shu nodded as he spoke, "Yes, it's still the right hand." The deceased's CT scan showed that he did not have a crushing ulna or piercing the shoulder blade in his back, indicating that his arms were not stretched outward or protected in front of his face, which means that he may not have been conscious when he fell downstairs. ”

Zhou Yinglin also agreed at this time and said: "Let's not say whether what this little brother said is true or false, but if the deceased is really knocked out, it is not impossible to leave the stairs behind." Then I'll put the body back in the freezer for a while longer and see if there are any potential injuries. ”

Xing Xie didn't care if what Lin Shu said was true or not, anyway, now that he had a direction, he immediately arranged it: "Xiao Zhou is carefully confirming the corpse, and then Xiao Zhang will take a team of people to continue the visit to see who had the last meal with the deceased, and whose can of Coke is." Lao Liu went to contact the parents of the deceased and asked them to come over to identify the body and ask questions by the way. ”

"Yes."

Four

Lin Shu sat on the sofa in the office of the Criminal Investigation Brigade, gnawing on his nails while recalling the details of the case little by little, he always felt that he had missed something important.

At this time, Xu Rong walked over with two buckets of instant noodles and handed Lin Shu a bucket, "It's almost 2 o'clock, you haven't eaten anything, let's eat some instant noodles first, let's take you to eat delicious food when you get off work." Then he quietly looked around, stretched out his head and whispered to Lin Shu: "Tell Uncle quickly, how did you force Blackface Xing to keep you in the team?" ”

Lin Shu, who hadn't eaten breakfast, was already hungry, and he started eating instant noodles regardless of whether they were soaked or not, and muttered, "Have you forgotten that I have a major in addition to law?" ”

"What kind of anthropology is that?"

"Uncle Rong, that's forensic anthropology, I originally wanted to accumulate more practical experience and find a place to intern, so I went to ask my cousin, and it happened to be arranged here.

Xu Rong showed a smile on his face: "No wonder the black-faced Xing Qicheng can only let you stay like that, after all, it is arranged by the Li Bureau of the City Bureau." ”

I don't know how long it took, but Lin Shu still didn't figure out what made him feel wrong. Xing Xie's shout interrupted his train of thought: "Ma Dongsheng's parents are here, you can also go to Xiao Zhou's side to help take a look, after all, they are also people you know." ”

Lin Shu followed Xing Xie's guidance to the corpse room, but rather than the corpse room, it was actually an ordinary room, with a large table in the middle and a few wreaths in the corner. Ma Dongsheng was lying peacefully on the table in the middle at this time, and it could be seen that in order to make him look like a person who fell to his death, Forensic Doctor Zhou had put in a lot of effort.

Lin Shu, who was standing outside the door, looked at the two middle-aged people who had lost their sons inside, and his heart was full of mixed feelings.

Ma's father's name is Ma Qiang, his hands and feet are stout, he should be a person who often does manual work, at this time he is silent, his hands are supporting the table, it is difficult to guess what he is thinking. Ma's mother's name was Liu Hongmei, a thin and weak woman, sitting aside, letting tears and snot flow, her eyes full of despair.

Maybe it was because the blow of losing his son was too big, Ma Qiang suddenly began to hammer the table vigorously again and again, and began to roar loudly, "I don't believe it, my son is so good, how can he die, how can he ......"

may also see that Lin Shu is not suitable for such a scene, Zhou Yinglin walked over and handed him a cup of coffee, "If you continue to intern in this place in the future, you will experience such human tragedies one after another, and what we can do is to work hard to seek the truth and return them to a clean house." ”

Lin Shu, who took the coffee, did not speak, but looked at them quietly.

After the father and mother calmed down, Zhang Dong took them to the sofa in the office and began to ask simple questions.

"Usually Ma Dongsheng told you that he has any enemies, money or emotional disputes?" Zhang Dong asked, and Ning Xiaoxiao recorded it. It seems that this petite female police officer is a proper tool person.

"No, Xiaosheng rarely tells us about school." Ma Qiang shook his head.

"Then what is your family atmosphere, is it harmonious, do you think Ma Dongsheng may commit suicide?"

Perhaps it was the word suicide that stimulated this strong father, Ma Qiang pressed his hands on the coffee table excitedly, "How can I commit suicide, I work hard to make money every day and give him everything, I just hope that he will get ahead, he will never commit suicide." ”

In this way, Zhang Dong questioned the Ma family's parents in detail and sent them away.

Lin Shu, who was watching the whole time, said to Zhou Yinglin beside him: "Forensic Doctor Zhou, have you noticed that Ma Mu has not answered a word from beginning to end. ”

"And they're all deliberately avoiding the issue of family harmony."

"Sure enough, you saw that one in the morgue just now."

Zhou Yinglin nodded, "There must be something wrong with their family." ”

Five

Unconsciously, an afternoon passed, and the policemen led by Zhang Dong brought a few people back one after another to be questioned and left.

"Let's come over and have a meeting for Lao Tzu, the questioning is over, let's exchange case information and see if there are any new ideas." Xing Xie shouted in the middle of the office.

One after another, the police, forensic doctors, and people who checked the traces came.

"Then let me say it first, I basically recorded the questioning in the afternoon." Ning Xiaoxiao, a petite tool man, stood up, "First of all, the victim's relationship map, the victim Ma Dongsheng, 22 years old, a sports student at Anyang University, has a relatively simple social relationship, and has not found the enemy for the time being." The victim's father's name is Ma Qiang, who is a porter, and his mother's name is Liu Hongmei, a housewife, who has not found any motive for the time being, and was sleeping at home at the time of the crime. ”

"The victim's girlfriend Wu Wan'er, 22 years old, a senior economics student at Anyang University, saw the deceased at around 9 p.m. on the day of the crime, and stayed until 10:30, and Wu Wan'er's testimony mentioned that 'Dongsheng likes to drink Pepsi, so I bought him a can of ice Coke at 10:30, and then I went back to the dormitory to watch the drama with my roommates and never left."

"The victim's friends Xiao Qiang and Li Guobin, students with sports specialties at Anyang University, have not shown obvious motives for the time being. According to his testimony, the three of them had dinner together at Chaoshan Porridge Village that night, and at about 8:30 a.m., the victim offered to pick up his girlfriend from class and left first, while Xiao and Li continued to drink until 11 a.m. and left the restaurant. Ning Xiaoxiao paused and continued: "After 11 o'clock, Xiao Qiang said that he went to Xiaoshan Park for a walk to sober up, but so far we have not found any witnesses, Li Guobin said that he drank too much and lay in the grass on the sidewalk of Jianshe Road, and it was more than two o'clock in the morning when he woke up. ”

"However, according to Forensic Doctor Zhou's inferences and known testimony, we can know that the time of the victim's death should have been between 11 p.m. on the 16th and around 0:30 a.m. on the 17th."

"As for the reason why the deceased went to the rooftop of the old activity building, according to Xiao and Li, it was because there was no one to take care of it, and they would often go there to smoke and drink all night."

"Well done, Xiaoxiao." Xing Xie looked at the others again, "Do you have anything else to add?" ”

The silence surrounded everyone, and everyone present did not speak, as if they were afraid of saying something wrong.

Xing Xie pursed his lips dissatisfied, and asked again: "Or is there any new direction?" Lao Liu, you are an old criminal investigator, what do you say. ”

Liu Jianshe could only bite the bullet and say: "I suggest that now that we don't have more information, we can focus on Xiao Qiang and Li Guobin, they don't have an exact alibi, and at the same time, we can't trust Wu Wan'er too much, after all, if her roommate sleeps, she also has a chance to sneak out to commit the crime." ”

Xing Xie nodded, "Well, then Lao Liu, you take a team to check the monitoring along the way, visit passers-by, and confirm the situation of Xiao and Li, Xiao Zhang, you take Ning Xiaoxiao to the girls' dormitory to feel the line." After speaking, he didn't forget to say to Lin Shu: "Who is that, you are an intern who has gotten off work at the end of the day, give Lao Tzu a slippery roll." ”

Looking at the others who were still busy, Lin Shu did feel that it was useless for him to stay here now, so he packed up and left.

Lin Shu, who was about to ride a bicycle back to his rented house at the door of the police station, looked at the right hand of the handlebar of the shared bicycle he was holding, and suddenly seemed to have figured out something, and he pedaled frantically in one direction when he got on the bike......

Six

At half past eight in the evening, when the criminal investigation team was still running around for Ma Dongsheng's case, Lin Shu had already hung up Uncle Rong's phone with a hint of victory on his face, "This is how they are all connected." "I started to pedal hard in the direction of the high-tech district office.

Then he got tired and said, "If I hadn't had no money, I would have taken a taxi a long time ago." ”

When Lin Shu stepped into the office of the Criminal Investigation Brigade, he happened to meet Zhou Yinglin, who also rushed over. The simultaneous arrival of two people attracted the attention of many people.

"Did you find out too?" Lin Shu looked at Zhou Yinglin with a smile.

"I think my discovery will change the direction of our investigation." Zhou Yinglin showed a standard smile.

"I think mine too."

"Laughing fart, two little kids." Xing Xie roared angrily, "I didn't see Lao Tzu annoying, there is something to say, nothing to do." ”

Lin Shu scolded silently in his heart, "Yes, yes, I have a big brain hole, what if there is no one else around when the deceased dies?" ”

Zhang Dong immediately asked at this time: "You mean suicide?" How do you explain the bloody Coke, didn't you say that you saw someone smash him with Coke in the afternoon? ”

"Comrade Zhang, your idea is limited." Lin Shu scratched his head embarrassedly, "Although I thought so at first, I always felt that something was wrong, until I held the handlebar of the bicycle with my right hand. ”

Ning Xiaoxiao also popped out at this time and said, "I still don't understand." ”

Lin Shu picked up a brick that he had just picked up on the road and began to demonstrate, "If a normal person wants to smash someone with a Coke with his right hand, he should swing to the right like me, swing from the outside of his body to the inside, and knock from right to left." As he spoke, he waved at the black-faced Xing, "But what I saw was like holding the handlebars of a bicycle, with the tiger's mouth to the left." So is it possible that this right hand is actually the deceased's own? ”

"You mean the dead knocked themselves out? I beat myself? Ning Xiaoxiao was completely confused.

At this time, Forensic Doctor Zhou stood up and explained in place of Lin Shu: "I think what Lin Shu wants to express is that the effect of that can of Coke has never been to create pain, but to relieve pain. ”

"Analgesia?" Almost all of them raised questions.

"Yes, I froze the body and re-examined it again, and found potential injuries that I didn't find in the first autopsy. There was an inconspicuous subcutaneous hemorrhage on the deceased's right back occipital, which was a blow injury. ”

Zhou Yinglin continued despite the surprise of the others: "The deceased was not a scar physique, based on the depth of the scars, I determined that the injuries occurred a few hours before death, and the murder weapon was a blunt object with an arc surface. ”

Xing Xie touched his newly grown slag and pondered for a moment, "That is, the deceased was attacked a few hours before he died, and then he wanted to go to the old activity building to stay for a while, but he suddenly felt pain in his back pillow, so he used the ice cola given by Wu Wan'er to relieve the pain?" How do you explain the blood stains on the Coke? ”

Zhou Yinglin continued: "The wound of the blow wound did have a slight wound, and when I first examined the autopsy, I thought it was a cut caused by a tree branch, but now it seems that this is not the case. In addition, I extracted a cactus-like thorn from the wound and handed it over to the Trace Forensics Department for testing, and I believe that the results will be available soon. ”

"That's not right, even if he was beaten elsewhere a few hours before he died, didn't he walk to the activity building by himself later, then it proves that the blow injury was not the cause of death." Brother Zhang Dong helped everyone raise the biggest question.

"Not like this, I found a lot of blood clots in the deceased's right posterior occipital skull, as well as partially ruptured blood vessels, normally a high fall injury will not cause such an injury as a non-contact surface, so according to the current situation, I make the most reasonable inference is that the deceased had suffered a blow a few hours before his death, and the blow caused a rupture of intracranial blood vessels, and the oozing blood formed a blood clot and re-blocked the ruptured capillaries. Alcohol reduced his perception of pain, and when he felt pain, he subconsciously used ice cola in his hand to relieve pain, but the freezing caused the blood vessels to constrict, and the originally blocked capillaries were suddenly dredged, and a large area of intracranial hemorrhage caused acute brain herniation in an instant, and then tragedy happened. ”

Xing Xie concluded: "In other words, even if the blow before the death of the deceased was not a direct cause of death, it was also an indirect cause. ”

It was at this time that Qi Xin from the Trace Examination Department ran in with a physical evidence bag, "It's bamboo, and the thing in the wound is bamboo." ”

When Lin Shu heard that it was bamboo, a smile of victory climbed up his cheeks again, "That's right, the following is my part, after figuring out the analgesic Coke, I went to Chaoshan Porridge Village to ask the boss if anything strange happened to the three of them last night, the boss said that because they basically ate at this table for one night, so they remember it very clearly, about seven o'clock when Ma Dongsheng heard a phone call and ran out nervously, about half an hour later, I also passed Uncle Rong and Xiao Qiang, Li Guobin and the others confirmed. As he spoke, he didn't forget to point at Xu Rong with his chin.

Xu Rong also nodded to everyone present to confirm, "I checked the victim's phone, the time was 7:41, the caller was the victim's mother, and the call lasted only 8 seconds. ”

Lin Shu then threw out another question: "What kind of phone call is that, only 8 seconds can make my son so nervous?" Zhou Forensic Doctor, you should know. ”

Zhou Yinglin, who was suddenly mentioned, was stunned for a moment, and then seemed to recall something and said: "It should be domestic violence, Ma Qiang should have the habit of long-term domestic violence against Liu Hongmei, I found out with Lin Shu in the corpse room before, Ma Qiang just raised his hand, and Liu Hongmei on the side subconsciously dodged, which is the most instinctive stress reaction." ”

"That's right, it's domestic violence. And then in the end, there is the murder weapon, bamboo products, with an arc surface, combined with Ma Qiang's profession as a porter, it should have been revealed. ”

"It's a flat dan!" Ning Xiaoxiao figured it out at once.

That is to say, at 7:41, Ma Dongsheng received a call from Ma's mother saying that his father immediately left the hotel and returned home to protect his mother after starting domestic violence again, and then was hit on the right back pillow by a flat shoulder in the fight with Ma's father at home. So according to this statement, Ma's father and mother are closely related to Ma Dongsheng's death, Xiao Zhang, you immediately lead someone to control the two and look for the murder weapon. Xing Xie immediately began to arrange for the arrest.

"Yes."

As the flat pole stained with the blood of Ma Dongsheng and Liu Hongmei was found in Ma's house, Ma Qiang confessed to the fact that he was domestic violence and injured his son by mistake.

In the courtyard of the Public Security Bureau of Anyang High-tech Zone, three girls sat in the sun and chatted.

"Sister Yinglin, do you think the court will convict Ma Qiang of negligence causing death?"

"We've done everything we can, and we're going to trust the courts for the rest."
