Chapter 148: The True Cause of Death
"Throw a corpse after death??"
Han Lu's shock was really wave after wave.
Chen Xiao's eyes were also full of disbelief, "Forensic Doctor Li, are you serious?" ”
Li Xiyang didn't answer directly, but asked rhetorically, "Can the corpse be autopsied?" ”
Han Lu was silent, slightly hesitant.
Theoretically, the police have already notified the other party's family, and it is best to wait for the family to see their relatives again.
But if it really involves murder, it's different.
Moreover, both the forensic department and the criminal police brigade have the right to directly dissect the eucalyptus without the consent of the family as long as they have doubts about the eucalyptus.
But
Although the policy is like this, if the person is dissected and no evidence is found, there must be complaints from the family.
Usually in this situation, the criminal police brigade will have a headache.
Seeing that Han Lu didn't speak, Li Xiyang took her as a default.
The scalpel at the head of the bed,
Very bright,
It's even a little dazzling.
Li Xiyang quickly picked it up, and then dropped it.
A standard Y-shaped incision was made.
Han Lu tugged at the corners of his mouth, and said in his heart that this guy's knife is too fast.
If he goes to sin, he will definitely be a necromancer.
Soon, the corpse's chest and abdomen were torn open, and the internal organs were exposed.
Li Xiyang said quickly, "Drowned corpses will have unique internal characteristics, such as lungs. ”
"Because a large amount of river water enters the alveoli, the air in the original alveoli is squeezed to the edge of the lungs, which will make the lungs of the drowning person have both edema and emphysema, which is also called "watery emphysema" clinically.
This type of lung is swollen in size, the surface is pressed by the ribs and has indentations, and the weight is also significantly increased;
In particular, after the rupture of pulmonary capillaries, scattered colored hemorrhagic spots form on the surface of the lungs, especially in the lower lobes and interlobar sulcus, called 'drowning spots'. ”
Sure enough, with the several places pointed by Li Xiyang's scalpel, Han Lu and Chen Xiao did not see the so-called watery emphysema, as well as drowning spots.
"In addition, in the process of drowning, because a large amount of river water is sucked into the respiratory tract, when the drowning person is dissected, it is often found that there is river water in the throat, trachea, bronchi and bronchioles of the deceased.
Occasionally, foreign objects such as sediment, aquatic weeds and plant debris can be found that absorb people along with the river water.
If the body is thrown after death, the sediment sometimes enters the mouth and nose, but usually only to the throat and rarely enters the trachea. ”
As the words fell, the corpse's trachea was also cut.
Sure enough, there was not a single trace of drowning or sediment.
Han Lu and Chen Xiao looked at each other.
Li Xiyang continued, "In fact, there are many other obvious organ characteristics of drowning people, such as the difference in blood composition between the left and right heart, whether there is drowning fluid in the digestive tract, and whether diatoms can be detected in the internal organs.
But what convinced me most of all that the dead were thrown after death was this! ”
Li Xiyang sighed, and then quickly cut open the muscles on the back of the corpse.
"What do you see?"
Li Xiyang looked up at Han Lu.
Han Lu stared at the woman's spine bone and groaned slightly.
At this time, Chen Xiao clapped his palms and said, "I know that the bones of the corpse are all broken, just like the man just now, which means that they all fell from a high altitude." ”
"Nonsense!"
Han Lu glared at him directly, "It is said that the corpse jumped from the Xiliang Bridge, isn't that a fall from a high altitude!" ”
"Yes, hehe, forget, forget..."Chen Xiao looked embarrassed.
Glancing at Chen Xiao, Han Lu said to Li Xiyang, "You shouldn't just want to say this, right?" ”
"Of course!"
Li Xiyang nodded, and then pointed to the traces of the corpse's ribs and said, "The bones of the corpse are broken all over the body, which meets the characteristics of falling from a height, but if you look carefully, the bones behind the corpse are obviously much more fragmented than the bones in the chest." ”
Han Lu, "What does that mean?" ”
Li Xiyang looked at the latter with a strange expression.
hemp eggs,
Not again
It's this look again.
Han Lu felt contempt and insult again.
Of course, Li Xiyang didn't mean that, he was just a little strange, "Don't you really see anything at all?" ”
Han Lu, "......"
Didn't you see that the old lady's eyes were about to pop out, and asked!
Ask me, ask your uncle!
Asked you to do an autopsy, didn't you ask questions, okay??
But when he saw Li Xiyang's sincere eyes, Han Lu was completely defeated.
"Okay, big brother, can I beg you?"
"Don't sell it, just say it!"
Chen Xu snickered on the side.
There are times when the vice team can't take advantage,
It's been a long time!
Li Xiyang shrugged his shoulders, "Okay! ”
Then he said, "The bones behind the body were very broken, which indicates that the deceased entered the water with his back lying flat." ”
Han Lu nodded, still waiting for the next step.
Then I saw that Li Xiyang had already put the body back in place.
What?
Gone?
That's it?
Han Lu looked confused.
Li Xiyang looked up at her, and said in his heart, didn't he understand what he said enough?
So he asked, "If you were a dead person and you had nothing to love in life, how would you jump into the river?" ”
After speaking, Li Xiyang added, "I mean what kind of posture it will be!" ”
Posture?
Han Lu frowned slightly, "That must be standing on the bridge, going down..."
Without finishing his words, Han Lu finally reacted.
"By the way, if a person really wants to jump into the river to die, it must be desperate, there is nothing to love, usually facing the river, jumping down, this way of jumping into the river with his back to the river, is really not normal!"
"And if... If the body is thrown after death, it seems to be easy to explain. ”
The murderer first killed the person, then carried the body on his shoulder, and then threw it off the bridge with his back to the river ...
Thinking about all this, Han Lu's whole person is not good.
What I thought was a murder turned into an accidental death.
Now he jumped into the river to commit suicide, and it has become his murder again!
Ever since he met Li Xiyang, Han Lu suddenly had a feeling...
The eucalyptus that I used to break,
It could all be false eucalyptus!
!
"And I have one more piece of evidence, although it's a bit of a hassle to verify..."
"Big brother, it's okay, let's not talk about the trouble!"
Han Lu is really convinced.
The previous eucalyptus, that was to find a piece of evidence are amazing.
This guy is good, and he has said a dozen pieces of evidence before and after.
You didn't slap me in the face loud enough, huh?
And now that it is known that the deceased threw his body after death, it is also his killing, and he can be killed.
I'm not as good as you when looking for clues on the corpse, and catching the murderer is Miss Ben's forte.
"Chen Xiao, as soon as the family arrives, immediately ask the deceased's name, age, occupation, and friend network..."
Han Lu's voice just fell, and before Chen Xiao could react,
I heard Li Xiyang say again, "The deceased is about 26 years old, and his profession is a teacher!" ”
“???”
Han Lu's cheeks twitched twice, "This... You can tell from the corpse as well? ”
Fortunately, Han Lu knew that some powerful forensic doctors could judge from the teeth and bones of the deceased.
My Healing Game
But this profession...
Isn't it carved into the bones as well?
Li Xiyang's corpse said on the right hand, "Her index finger and middle finger joints have protrusions, which are only found by clerical workers who often use pens, and the calluses between her thumb and index finger, I guess it should be often sharpened with chalk." ”
What else can Han Lu say?
In addition to shock, it is still shock!
Miss Ben is the deputy captain of the criminal police brigade, and she will become a fool when she meets you!
Are the forensic doctors so powerful now?
"You, you..."
Han Lu didn't know what to say at all, Li Xiyang had too much impact on her.
"Doctor Li, you're amazing, why don't you check the eucalyptus with us?"
Chen Xiao admired Li Xiyang.
But Han Lu hurriedly stopped, "No! ”
"Why Team Han?"
"Because... Because..."
Because the old lady is about to start doubting life.
Can't let this guy continue to show anymore.
Han Lu was crazy in his heart, but he still tried to maintain a calm look on his face, "Because Dr. Li has other jobs, right?" ”
Li Xiyang nodded, he really had a lot to do.
The trip to the imperial capital is scheduled for the day after tomorrow, and he needs to go back to the rental house to clean up.
Seeing Li Xiyang nodding, Han Lu immediately breathed a sigh of relief,
"Look, Dr. Li still has something to do, so what, Dr. Li, we have to hurry up, and I won't send you!"
"Well, you're busy!"
……
Not long after Li Xiyang left the forensic department, a middle-aged couple hurriedly walked in.
Seeing their daughter on the hospital bed, the two were crying.
Afraid that something would happen to the family again, Han Lu and Chen Xiao hurriedly invited the two outside.
After some understanding, the deceased's name was Liu Weiwei, 26 years old, a Chinese teacher at Nancheng Experimental Middle School.
Han Lu couldn't help but glance at Chen Xiao, and Dr. Li really guessed correctly.
"What, family, in fact, your daughter was killed by him, not suicide!"
"You, what do you say!
”
Then Han Lu told the two old men the true cause of Liu Weiwei's death.
The first is that they have the right to know, and the second is that only in this way can the two family members cheer up and fully cooperate with the police investigation.
After recording the confessions of the two old men, Han Lu targeted two places.
It is said that according to the family, Liu Weiwei's circle of friends is very narrow, and almost every day is two points and one line: home, school!
So Han Lu sent a three-person team to Liu Weiwei's house to find clues, and the others followed Han Lu to Nancheng Experimental Middle School.
……
7:00 p.m.
The teaching building of Nancheng Experimental Middle School is still brightly lit.
The students studied in the classroom in the evening, and Han Lu gathered all the school staff in the conference room.
The criminal policemen made notes for them one by one, mainly asking Liu Weiwei how popular she was before her death? Who are your friends? Do you have a grudge against someone?
Or have you heard any rumors?
The cross-examination lasted nearly two hours, and the results were very similar.
It is said that Liu Weiwei is beautiful, gentle and gentle, has a good relationship with colleagues, and has never heard of any enemies.
"It's weird, could it be that the murderer killed people randomly?"
If that's the case, then it's going to be a big deal.
At this time, Chen Xiao ran over, "Team Han, there is a major discovery!" ”
"What discovery?"
Chen Xiao whispered a few words in Han Lu's ear, and Han Lu's eyes instantly became sharp.
"Principal of Nancheng Experimental Middle School, Lu Wencai..."
……
At eight o'clock in the evening, Lu Wen was taken to the interrogation room of the criminal police brigade.
"Captain Han, what do you mean by that?"
Lu Wencai was holding an online meeting at home, and he was suddenly taken to the police station with a dissatisfied face.
Han Lu looked Lu Wencai up and down, gold wire glasses, suit and leather shoes, although he was older, but he had to admit that in terms of appearance, this Lu Wencai was indeed different from the ordinary greasy uncle.
No wonder!
Han Lu said directly, "Principal Lu, don't worry, please come here, it's definitely not tea, I want to ask if you know Liu Weiwei?" ”
"Vivi?"
"Ahem, you... You mean Teacher Liu Weiwei! ”
Lu Wencai blurted out the title, which made Han Lu and Chen Xiao look at each other and smile.
Previously, when a group of teachers asked for no result, Chen Xiao heard an amazing news from the uncle of the school's boiler room.
That is, the principal Lu Wencai and Liu Weiwei have an improper relationship.
Now, this thing must not be faked.
"Tell me, how did you kill Liu Weiwei and then throw the corpse into the river!"
"What did you say?"
"Liu Weiwei is dead?!
”
Lu Wencai stared, looking unaware.
"Heh~"
"Still pretending?"
Han Lu took out a stack of documents and threw them in front of Lu Wencai.
"Let's see for yourself, this is the last two months, the call records between you and Liu Weiwei, no less than 3 phone calls a day, the longest can be more than three hours, don't tell me you are talking about work!"
Lu Wencai looked at the thick communication paper, with a complicated expression on his face,
After a moment, he let out a long sigh and nodded in acknowledgement, "That's right, Weiwei and I did hit it off at first sight, and we hated seeing each other late..."
"Stop, stop!"
Han Lu couldn't listen to it anymore, what nonsense was being said.
A whipped goosebumps from nausea.
"Don't talk to me idioms, just say how you killed Liu Weiwei!"
"Kill Liu Weiwei? I? How can it be!
”
Lu Wencai suddenly became excited, "We are confidants, each other's soul mates, how can I kill her, besides, how dare I kill someone, I don't even dare to kill chickens, that's human life, human life, don't frame me, okay!" ”
Chen Xiao, "Team Han, this person doesn't cry when he sees the coffin!" ”
Han Lu snorted coldly, "Then let him see the coffin!" ”
As he spoke, he flipped to the last page of the communication paper.
The time was 8:24 last night, and the call lasted 47 minutes!
Lu Wencai frowned, "I called him, so what's the matter?" ”
"What's wrong?"
Han Lu sneered, "Liu Weiwei left the house in a hurry after nine o'clock last night and was finally killed, didn't you tell her to go out?" ”
"What?!" Lu Wencai looked shocked.
Han Lu smiled, "Remembered? ”
Lu Wencai's face changed, "I don't understand what you say at all, I did call her yesterday, but I went to sleep after nine o'clock." ”
"Sleeping?"
Han Lu and Chen Xiao glanced at each other, knowing that this guy was going to play tricks.
"Can anyone prove it?"
Lu Wencai shrugged his shoulders, "My wife happened to be on a business trip, and I was alone at home!" ”
"So coincidentally?"
Lu Wencai spread his hands.
Han Lu turned to Chen Xiao and said, "Go, call his wife." ”
Chen Xiao nodded, just stood up,
Lu Wencai smiled and said, "By the way, give my lawyer a call!" ”
"Humph!"
The two walked out of the interrogation room with annoyed expressions.
"Team Han, what now?"
"You go call first!"
"Do you want to call his lawyer?"
Han Lu sighed helplessly, "Let's fight!" ”
It's the right of the other side, and they can't stop it.
……
Not long after, the opposing lawyer came.
Chen Xiao finally got in touch with Mrs. Lu Wencai, who had been busy in the line.
The other party is indeed on a business trip out of town, and he will not be able to return until the day after tomorrow at the earliest.
"The day after tomorrow..."
Han Lu frowned.
Lu Wencai was taken to the Criminal Police Brigade to assist in the investigation.
According to the regulations, summons for public security cases shall not exceed 8 hours, and criminal cases shall not exceed 12 hours.
Now that the opposing lawyer is here, Lu Wen will not speak.
Apparently it was intended to delay until 12 hours to release the people.
"Damn!"
Han Lu looked at Lu Wencai's face, only felt extremely disgusted, and said to Chen Xiao, "Go to the vicinity of Lu Wencai's house to get surveillance, I'm sure this guy must be lying!" ”
"Good!"
……
12 p.m.
Han Lu's phone rang.
"Team Han, I've checked the surveillance, Lu Wencai hasn't been out since he came home from work yesterday!"
"Are you sure?"
The other side was silent for a while and said, "Surveillance is indeed like this. ”
"You go into the apartment and see if there's a back door, or a path that can avoid surveillance!"
"Good!"
……
Two o'clock in the morning.
"Team Han, I've searched the neighborhood several times, there is no back door, and I also looked at the surveillance in front of the gate, even if he avoided the surveillance of the apartment, but the exit was not photographed here!"
"Could it be that he's not lying, it's really not him?"
"Impossible!"
Han Lu accurately captured the change in Lu Wencai's expression, he must have hidden something.
"Team Han, then I..."
"Forget it, you can come back first!"
"Okay!"
In the middle, Han Lu entered the interrogation room and interrogated him three times, but each time he was interrupted by the lawyer with various excuses.
The interrogation simply did not proceed.
……
7 a.m.
"What to do with the Han team, there is only 1 hour left!"
Lu Wencai always insisted that he and Liu Weiwei were just chatting confidants, and there was no actual improper behavior.
And the police don't have any conclusive videos or recordings.
Even the words of the boiler room uncle were only heard, and he did not see them with his own eyes,
Therefore, the police could not identify Lu Wencai based on communication records alone.
Seeing that there was only one hour left, Chen Xiao said cautiously, "Team Han, why don't you find Dr. Li?" ”
"What are you kidding?"
Han Lu's reaction was so big that it was like someone stepped on his tail.
If you say that you were slapped in the face in front, you can comfort yourself with the difference in the field.
Now it's obviously the time to reconnoiter and break the eucalyptus, and she knows that the murderer is inside, if she begs Li Xiyang again, does she want this face?
"Hmph, I don't believe it!"
Han Lu opened the door of the interrogation room again and walked in.
"Lu Wencai, do you want to say it?"
"I can tell you, if you recruit now, you may be able to sentence you in the future, but if we find out, you really have no chance!"
Lu Wencai spread his hands, "Captain Han, I also want to cooperate with you, but I really don't know what you're talking about!" ”
"Damn..."
"Captain Han, please pay attention to your attitude, my client is here to assist in the investigation, and at the same time has the right to remain silent!"
Lu Wencai's lawyer is a gold medal in Yuncheng,
Looking at the two of them looking like villains, Han Lu was furious.
But those two can't help it.
I could only grit my teeth and slam the door.
……
"Team Han, there are only forty minutes left."
"When the time comes, we're going to release them."
Chen Xiao kept thinking in Han Lu's ear, and Han Lu was also convinced.
Alas!
Shaking his head and sighing, Han Lu still dialed Li Xiyang's phone.
At this time, Li Xiyang just got up and picked up the phone, "Which one?" ”
Han Lu's face stiffened, this guy didn't have Miss Cunben's phone.
However, as soon as he thought of asking someone for something, he suppressed his anger and said, "Doctor Li, I'm Han Lu." ”
"Oh, Captain Han, what's wrong, what's the matter?"
"Hehe, that's it, what, actually, it's..."
Chen Xiao was anxious when he heard it on the side, and grabbed Han Lu's mobile phone and said, "Doctor Li, I'm Chen Xiao, or the eucalyptus yesterday, the murderer has also been caught, but I'm in some trouble, can you come over?" ”
"Is that so..."
Li Xiyang groaned.
"What's the matter, Dr. Li, is there anything inconvenient?"
"Oh, I'm going to the imperial capital tomorrow, and I still have a lot of things to collect at home!"
"To the imperial capital?"
"Well, a temporary arrangement in the hospital!"
Han Lu was still angry with Chen Xiao's self-assertion, but when he heard that Li Xiyang was going to the imperial capital,
hurriedly said, "It's simple, you come over first, and I'll let Chen Xiao help you clean it up when you go back!" ”
Chen Xiao squinted at Han Lu, but still said, "Yes, Doctor Li, I'll go back and help you, if there are not enough people, our Han team will also go over together!" ”
Han Lu, "I..."
"Ahem, I... It's not impossible! ”
Li Xiyang, "Okay then! ”
Chen Xiao and Han Lu were overjoyed, "Then we'll go over and pick you up!" ”
"No need, you may not be able to find where I live, I'll take a taxi myself!"
"Okay, let's see you at the police station later!"
"The police station?"
"No, let's go to the forensic department first!"
……
Twenty minutes later,
Li Xiyang got out of the car at the entrance of the forensic department.
Han Lu and Chen Xiao rushed to meet them head-on.
As soon as they met, Han Lu looked dissatisfied, "Why did you come to the Forensic Department?" I've told you that time is running out! ”
"Captain, listen to Dr. Li first, since Dr. Li is here, there must be a reason..."
Before Chen Xiao finished speaking, he saw that Li Xiyang had already walked in by himself.
Han Lu glanced at Chen Xiao, "What is the reason?" ”
"Ahem!"
Chen Xiao scratched his head, "Then there is still time anyway, let's go and take a look first." ”
Han Lu had no choice but to call back to the bureau and tell the team members to find a way to drag Lu Wencai before she went back.
Hanging up the phone, Han Lu hurriedly chased after him.
……
In the autopsy room, Li Xiyang pulled Liu Weiwei's body out of the freezer again.
"What the hell are you going to do?"
"You're not going to have to dissect it, are you?"
"Why don't you go to the bureau with me first, and then dissect it when you come back?"
Han Lu was anxiously urging while staring at the time.
Li Xiyang turned around, "You've been interrogating all night, haven't you?" ”
Han Lu was stunned, what do you mean?
Laugh at me?
Li Xiyang shook his head, "You are a professional, you can't ask anything, it's useless for me to go!" ”
As soon as these words came out, Han Lu's heart instantly felt a lot more comfortable.
Walking to the dissection table, Li Xiyang slowly squatted down.
At this time, Han Lu stared at Li Xiyang's movements, and his eyes showed doubts.
I saw him use a scalpel to gently scrape the edge of the nail of the right index finger of the corpse.
Soon debris fell into the pre-prepared specimen bag.
Han Lu leaned closer, "What is this?" ”
Li Xiyang didn't speak, but turned around and walked to the DNA identification instrument.
After about five minutes, the device made a dripping sound, followed by a DNA sequence on the screen.
Then Li Xiyang put something similar to dander, and at about a moment, another DNA sequence appeared on the screen.
Followed by two pairs of DNA sequences into the simulation matching stage,
The end result turned out to be different!
But how is it possible for a person to have two DNA sequences?
After Chen Xiao and Han Lu glanced at each other, they exclaimed almost at the same time, "Could this be the murderer's skin tissue?" ”
Li Xiyang nodded and walked back to the corpse, "Pay attention to both sides of the corpse's nose!" ”
Han Lu and Chen Xiao hurriedly approached, "Huh? There are bruises! ”
"No, it didn't seem to be last time!"
"I don't remember any bruises here!"
Li Xiyang explained to the two, "Corpses often float and roll with the currents in the water, and the posture is not fixed, and it is difficult for corpse spots to form in a low part of the body;
At the same time, the blood vessels and erector pili muscles of the skin shrink when stimulated by cold water, so that the bruises on the original skin will also become turbulent.
However, this kind of scar often reappears after a period of mortuary.
The killer apparently wanted to take advantage of this and cover up the fact that he had committed a crime. ”
As he spoke, Li Xiyang picked up the tweezers again and put them into the deceased's nose.
When taken out, a very tiny strand of fiber appears.
When Han Lu saw this scene, he instantly suddenly said, "Liu Weiwei was suffocated to death by someone covering her mouth and nose with a handkerchief." ”
Chen Xiao also continued, "Liu Weiwei was suddenly covered by someone from behind, so she subconsciously grabbed the man's hand, and the murderer's skin tissue was left in her nails. ”
Li Xiyang nodded, "That's it!" ”
"But why didn't you say it at the time?!"
Han Lu was furious, such an important clue was not said until now!
Li Xiyang looked strange, "You didn't let me say it!" ”
"What?"
"I won't let you say it?"
"You're funny..."
When the words came to his mouth, Han Lu was suddenly stunned, "Could it be that time?" ”
She remembered that the other party seemed to have said that there was still one piece of evidence, but it would be more troublesome to verify, so she said that it was troublesome, so don't talk about it.
"Team Han, it's really you who don't let people say it!"
Han Lu's cheeks twitched twice.
Get!
Slapped in the face again!
Li Xiyang, you must have been my nemesis in your last life!
