At 5:30 in the morning, Zhang Zaibo drove to S City Railway Station. At this time, the train station also seemed deserted. Zhang Zaibo didn't even park the car in the parking lot. He saw a tall and thin figure in the distance.
He was standing on the roadside dragging a big suitcase. When he came closer, he saw that it was his best friend, Song Dongxi, who had arrived by train overnight!
Song Dongxi didn't expect that Zhang Baojun would drive to pick him up. He looked at it for a long time and didn't dare to get in the car. It was Zhang Baoan who rolled down the window and called him, which made him get in the car with some disbelief.
As soon as he got in the car, Song Dongxi couldn't wait to say: "Damn, it's okay, Xiao Liangzi, it's only been a long time since graduation, and he's already driving a car with four laps!"
Zhang Liang rolled his eyes and said angrily: "If I had this ability, why would I still be hanging around here? This is my girlfriend's car!"
Song Dongxi immediately looked at Zhang Baoliang with a strange look, which made Zhang Baoliang tremble for a while. Finally, he couldn't bear it anymore. Zhang Baoliang shouted: "Can you stop looking at me like that? I'm not gay!"
Song Dongxi said quietly: "Don't worry, I don't like you either. I'm just wondering what do people like about you. Through the observation just now, I discovered that you are indeed fairer!"
Zhang Baoan was stunned for a while, and it took him a long time to react, and said angrily: "Damn it, you are such a pretty boy!"
Song Dongxi quickly waved his hand and said: "Don't be excited, don't be excited! Watch the road! Watch the road!"
The two of them returned to Zhang Liang's residence noisily.
In fact, Zhang Baojun was very touched by Song Dongxi's overnight arrival. After all, no matter how good a friend is, he may not always be able to be on call at all times, and besides, it was Zhang Baolan's case that might involve a murder case.
However, compared to Zhang Liang's emotion, Song Dongxi was not so moved. He looked at Zhang Liang's small room and hall and asked in disbelief: "Do you live in a place like this?"
Zhang Liang said as he took off his coat: "Yes, I'm just one person. How big of a house can I rent?"
Song Dongxi asked: "What about your girlfriend? You two don't live together?"
Zhang Liang spat: "Don't talk nonsense! We have only been dating for a month. Besides, we are both serious people, and we don't have as dirty thoughts as you!"
Song Dongxi curled his lips and said: "What a villain! Do you have to do something if you live together? I don't know who has dirty thoughts! Besides, I mean, brother, the point now is, where do I live? Should we squeeze in together?"
A bed?" He said, pointing to Zhang Baolan's bed that was single but not double, not double.
Zhang Lianyuan was also a little embarrassed, but he still said firmly: "Isn't my bed quite big? It can't accommodate the two of us? Besides, isn't this just to save you money on staying in a hotel? If it doesn't work, I
Make a bunk on the floor and sleep on the bed!"
Song Dongxi opened his mouth wider and wider as he listened to Zhang Bao'an's words. After holding it in for a long time, he pointed at Zhang Bao's lifeless look and said, "Are you still a human being?"
Zhang Baoan also felt guilty. He quickly changed the subject and said, "Are you hungry? I'll make you a bowl of instant noodles." After saying that, without waiting for Song Dongxi's reply, he put his coat on the table and picked up the hot noodles.
He quickly walked into the bathroom.
Song Dongxi no longer has the energy to complain about Zhang Baoan. After riding the train all night, he was already tired and hungry. He thought Zhang Baoan would entertain him with delicacies here, but he didn't expect that now he would not only eat instant noodles, but also a
There was no serious place to sleep! Song Dongxi lay down on the bed feebly, and could only sigh, and muttered: "If you meet someone unkindly, you will make careless friends!"
Zhang Baoliang pretended not to hear Song Dongxi's nagging, took the water and boiled it, took out two buckets of instant noodles and started to sprinkle the seasoning. Soon, the water was boiled, Zhang Baobo poured the boiling water on the noodles, and instantly,
The aroma spreads in this small space.
Song Dongxi was still mumbling about "the world is declining and people's hearts are not as old as they used to be", but after smelling the aroma of instant noodles, he jumped up from the bed like a cat that saw a mouse, and took a few steps.
When he came to Zhang Liang's side, he picked up a bucket of instant noodles and couldn't wait to eat it.
Zhang Baolian smiled slightly when he saw this, and without saying anything, he picked up another bucket of instant noodles and started eating too.
After a long while, both of them finished eating the instant noodles and drank the last mouthful of hot soup. Song Dongxi burped with satisfaction, put the instant noodle bucket aside, wiped the sweat from his head, went back to the bed and lay down, facing
Zhang Liang asked, "Hey, what are you guys doing here? You go to work later, and I'll go out for a walk by myself."
Zhang Baoan said while packing up the instant noodle bucket: "I'm not going to work today. You go to sleep for a while. I'll tell you something when you wake up." As he said that, he yawned first.
In fact, not going to work was a temporary decision made by Zhang Liang. He was originally hesitant to ask for leave today. Now that Song Dongxi was here, he investigated a lot of things that night, so he made a decisive decision to skip work for another day. Although he
I also know that my work attitude has been very problematic recently, but I can't help it. With Zhang's bad character, he really doesn't have the time to think about work.
However, Zhang Liang was not too "crazy" after all. He also knew that Song Dongxi had worked very hard that night, so he did not discuss his findings with him immediately, but asked him to have a good rest.
Song Dongxi is also a very observant person. When he saw Zhang Liang's tired look and thought about what he just said, he couldn't help but asked suspiciously: "Why did I hear something wrong? Could it be that you didn't sleep all night?"
Right? Did you go out to investigate again last night? "
Zhang Baoan nodded and said: "I did make some new discoveries, and I think they are quite crucial, but these require your professional knowledge to help me analyze them, so you should gather your energy quickly so that we can start the investigation quickly.
.”
Song Dongxi slapped his forehead with his hand and said helplessly: "Brother, I am really convinced by you. I told you not to act rashly before I came. Why didn't you listen?"
Zhang Liang waved his hand nonchalantly and said, "It's okay, time is tight. I was able to find these last night, which is considered my luck. If it were later, I'm afraid this clue would be broken again."
Song Dongxi knew that it was useless to say anything else, so he could only say: "Okay, okay, you are awesome. Tell me, what did you find out?"
Zhang Liang was surprised and said: "Why don't you get some sleep first?"
Sleep?"
Song Dongxi said angrily: "Can I still sleep now? Okay, I also slept a lot on the train, and I'm not very sleepy now. But you, you haven't slept all night, why don't you get some sleep first?"
Go to sleep!”
Zhang Bao Liang shook his head and said, "I'm fine. If you don't sleep, then I will give you these things I have investigated and you can help me analyze them." As he said that, Zhang Bao Bao took out his phone and pulled out the information from last night.
While showing Song Dongxi the photos I took, I briefly told him about his experience last night.
Song Dongxi was mentally prepared, but after listening to Zhang Bao's words, he couldn't help but be surprised, especially when he heard that Zhang Bao hid the old beggar's body back in the hospital morgue at the end.
"Trough" I couldn't help but said it.
Song Dongxi held the mobile phone, but no longer bothered to look through it. He just said stupidly: "To be honest, as a medical student, I have never come into contact with a real corpse. You are lucky enough to start carrying corpses around.
Got it!"
Zhang Baolian spread his hands and said: "There are specialties in the art industry. After all, you are doing testing. It is normal that you can't touch the corpse. So what do you think when you see these?"
Song Dongxi really wanted to ask Zhang Baoan back: "It's normal for me to learn detection and not be able to touch corpses, so it's normal for you, a computer worker, to often encounter corpses?" But after thinking about it, he still didn't say it. After all, it looked like
In Zhang Liang's current state, all his thoughts were focused on the old beggar's murder case, and he probably had no intention of joking. Thinking of this, he lowered his head again and began to carefully look at the photos on Zhang Liang's cell phone.
As soon as he entered the state, Song Dongxi's expression immediately changed. He kept flicking Zhang Baoli's mobile phone back and forth. Since Zhang Baoli was shooting at night and in a dark environment like a small dark room, even if
The flash was on, and some of the photos were not realistic, but Song Dongxi looked at them very carefully. Sometimes he would enlarge the screen to look at the details carefully, and then from time to time he would transfer a certain photo to his mobile phone and then send it out.
Zhang Baolian watched from the side, not daring to disturb him, but his eyelids gradually became heavy. No wonder, he had been "fighting wits and courage" this night. Now he can be said to be exhausted physically and mentally. Although what he is seeing in front of him
The clues were enough to arouse his interest, but physical sleepiness was still unavoidable.
Just when Zhang Baoan couldn't hold on anymore and fell down on the table, the sound of Song Dongxi putting his cell phone on the table suddenly woke him up. After more than an hour, Song Dongxi finally completed the preliminary review of the photos. He stretched out his
He stretched out his waist, stretched his slightly sore shoulders, and then said to Zhang Liangzi who was already looking at him with wide eyes: "Xiao Liangzi, I really want to impress you this time, these photos you took
, not only can you basically determine the cause of the old beggar’s death, but you can even determine all his experiences from death to now. Do you know, with these clues, you can get twice the result with half the effort no matter what you want to investigate!"
Zhang Liang was no longer sleepy at this time. Although he could vaguely predict that he would gain a lot this night, he was still a little embarrassed when he heard Song Dongxi's praise. He said: "You didn't say that."
It’s so exaggerated!”
Song Dongxi shook his head and said seriously: "Do you know what the police rely on most when handling a case? It is the forensic identification report! A professional forensic doctor can analyze the appearance, movements, trauma and other items or substances of the deceased's body.
, determine the time and even the passage of time when the deceased was killed, thereby helping the police restore the crime scene and the crime process, thereby narrowing the scope of the investigation and identifying the suspect."
What Zhang Bao Bao heard was a bit strange. He usually only knew about the work of forensic scientists from some fictional works such as novels and movies, and thought it was an exaggerated profession. He didn't expect it to have such a huge role.
Song Dongxi continued: "Actually, strictly speaking, forensic medicine is the profession with the strongest medical theory and practice. They basically have knowledge of anatomy, pathology, internal medicine and surgery, obstetrics and gynecology, toxicology, psychiatry, etc.
, and even need to master the knowledge of criminal investigation, physical evidence, etc., so you must not underestimate them. For a criminal case involving murder, the corpse is the best evidence!"
Zhang Baolian looked at Song Dongxi with a strange look in his eyes and said, "Why do you sound like you are a forensic doctor, and you are here to promote your forensic field!"
Song Dongxi may also realize that he was a little too excited just now, and said sheepishly: "Although I am not a forensic doctor, I can still be regarded as a doctor. Forensic doctors are also doctors. They are all colleagues and colleagues! Haha!" After that!
, and he said somewhat mysteriously: "Let me tell you, in fact, I really wanted to apply for the forensic medicine major at the beginning. You think, how handsome it would be, but my old man disagreed. He felt that forensic medicine dealt with dead people every day, so he might not return.
I had to deal with criminals, which was unlucky and dangerous, so I had no choice. In the end, they chose a tepid major like testing. They said that the work would be easy after I got out, and that I would have nothing to do if I stayed in the department every day. Alas, now
Isn’t that right? I was bored to death. Fortunately, you called me over this time. I was eager to sneak out and relax for a while!”
Zhang Baojun rolled his eyes after hearing this, and was so moved and guilty that he was completely blind. This guy had a plan to escape! He said angrily: "Okay, stop talking nonsense, talk about it quickly.
, what have you discovered?”
Song Dongxi said with some pride: "Although I am not a real forensic doctor, I have had thoughts in this area after all, so I have been working hard in this direction for a while. Come and see, let's talk about the appearance of this corpse first. You
What was your first feeling when you saw the corpse?"
Zhang Baoli looked at the photo and recalled the situation last night. He said with some uncertainty: "I can't say exactly how I feel. I just feel that for a person who has been dead for two days, the body is still so... Baili
It’s so red that it looks very weird!”
Song Dongxi nodded and said: "Actually, what you feel is right. For a normal corpse, because the blood stops flowing, it will accumulate in the lower parts of the body. Over time, corpse spots will form, which is what you will see later.
Those dark purple parts seen on his body. In contrast, the upper parts of the body will appear pale due to lack of blood."
Zhang Liang nodded to express his understanding, and Song Dongxi continued: "But don't forget, the old beggar died in the hospital, so he will definitely be placed in Taiping after his death."
room, and the morgue is full of large, ultra-low temperature freezers!”
Zhang Liang was confused and asked: "What does that have to do with the phenomenon that happened to the old beggar?"
Song Dongxi explained: "When a person dies, if he is immediately placed in an ultra-low temperature environment, the blood will be frozen directly because there is no time to fall. And if the body is thawed later, something like the one in your photo will appear.
The phenomenon of "white and rosy" is caused by the blood turning into a liquid state again. "
Zhang Liang thought for a while and said: "What you mean is that the old beggar was indeed put into the morgue on the night of his death, but was later taken out and put into a hut in the backyard of the hospital. This led to his corpse experience.
It's a process of being frozen first and then thawing, right?"
Song Dongxi nodded and said: "Actually, there are many points to prove this inference. For example, regarding rigor mortis, you said you felt that his body seemed hard but not hard. In fact, it was a state where rigor mortis had just begun to form, and freezing can delay the formation of rigor mortis.
The formation of stiffness and cadaveric plaques are the same. Furthermore, you said that his eyes were half-opened. This is also because the contraction of muscles due to low temperature caused the eyelids to be stretched open by the eyeballs. Therefore, the old beggar was removed from the morgue.
The hypothesis that the body was moved to a small dark room should be established."
Zhang Liang nodded, but did not express any further opinions. Instead, he motioned to Song Dongxi to continue: "The second point is that we will talk about the cause of his death. There is no doubt that the old beggar died of suffocation. The brown color you see on his gums
, is actually a bleeding phenomenon caused by suffocation, which is called "rose tooth" in forensic medicine. Moreover, if you look carefully at the old beggar's face, you will find that although it does not appear purple because it has just thawed, the entire face is swollen.
, this is also a sign of suffocation. In addition, if you see his blood, you will find that his blood must be dark red or even black purple. This is also one of the phenomena of death from suffocation..."
Just as he was talking, Song Dongxi was shocked to see Zhang Bao Li suddenly stood up and ran to the table where the water was boiling, picked up his coat and walked back. Then, he saw Zhang Bao Bao take out a bottle filled with dark red liquid from his coat pocket.
syringe and a small transparent bag.
Song Dongxi said in surprise: "What is this?"
Zhang Liang replied: "The old beggar's blood! Look, is it what you said?"
Song Dongxi's eyes widened and he said in disbelief: "Holy shit, you really got a tube of blood? You are... so professional!" Perhaps because he couldn't think of how to describe Zhang Lianyuan, Song Dongxi could only say this in the end.
He picked up the syringe, looked at it carefully, and nodded: "It should be about the same. Although I have never actually seen what the blood of a person who died of suffocation looks like, this blood is obviously darker than the blood of normal people, already showing a purple-red color.
It's probably caused by suffocation. I'll test it later to see what the blood oxygen concentration is inside." After saying that, he put the syringe aside, and then asked in a daze: "What were you talking about just now?"
Zhang Liang reminded silently: "Cause of death!"
Song Dongxi clapped his hands as if suddenly enlightened and said: "Yes, yes, the cause of death. What we can confirm now is that the old beggar did die of suffocation, but it should not be the ventilator problem you found before."
Zhang Liangliang asked in confusion: "What? From what you say, there are many other situations of suffocation?"
Song Dongxi nodded and said: "Of course, if you think about it, strangling someone to death is also suffocation, drowning in water is also suffocation, and even some nerve poisoning may also cause suffocation, but the death process in each case is different, so on the corpse
The final traces left behind are also different.”
Zhang Liang asked: "Then can you determine what kind of situation the old beggar belongs to?"
Song Dongxi shook his head this time and said: "This is a more professional clinical medicine. I'm still a little behind. Among the photos you took, the one with blood foam deep in the throat should be the most intuitive to show him.
Post-mortem symptoms, but I really don’t understand what it means. However, you don’t have to be disappointed. I just sent those relevant photos to the director of my clinical colleague and asked him to help us find out.
What is the situation?"
Song Dongxi had already helped him to this extent, so Zhang Baolian naturally had no objections. He said, "What's next, let's just wait for the result?"
Song Dongxi said: "Let's wait and see. However, I can do a test on the tube of blood you collected first. Although we can basically determine the cause of death, testing the blood oxygen content can be considered a relatively accurate value."
Zhang Baoan nodded, and Song Dongxi asked again: "By the way, what is this?" He pointed to the transparent pouch.
Zhang Liang briefly described the process of discovering the hair again. After hearing this, Song Dongxi's eyes lit up and he said excitedly: "Doesn't that mean that if we can find out the owner of these hairs, we can identify the suspect!
"
Zhang Liang did not agree immediately, but shook his head and thought deeply: "It's hard to say now. Don't forget, I did the same thing last time, and the result turned out to be like this." With that, Zhang Liang showed his face.
An expression that is unpredictable.
Song Dongxi didn't know how to answer the question, so he had to say: "Actually, you don't have to rush to a conclusion now. Maybe your previous thoughts were not wrong, but... you just need some other evidence."
Zhang Liang nodded calmly and said: "You are right, so now I understand that before the matter is clarified, anything is possible." He was silent for a moment, and then continued: "And, this matter
I have some ideas now. The whole thing seems messy, but in fact, someone has been doing something in a planned way. However, I still agree with one thing. If you can really detect the owner of the hair, maybe you can really detect it.
My speculations were of great help."
Song Dongxi didn't expect Zhang Liang would say these words in such a serious manner. He couldn't recover for a moment, but he quickly reacted and said: "I can detect the DNA in these hairs, but to be sure,
There needs to be a comparison of whose it is."
Zhang Liang thought for a while, then suddenly his eyes moved, he picked up his coat, stood up and walked out.
Song Dongxi was confused by his behavior and couldn't help shouting: "Hey, why are you going?"
Zhang Liang left the room without looking back, but a voice came from outside the room: "You do the test first, and I'll find something!"
