Chapter 579 Unexpected Evidence
When Lin Xinyi said this, everyone really didn't believe it.
He reached down and tore off a small piece of the hood, and everyone was quick to believe him again.
Then Lin Xinyi started from the hood, disassembled the front of the car bit by bit, and finally removed the whole thing.
Aramaki Giichi.zip, finally successfully decompressed without loss.
Lin Xinyi didn't care about the dirt, so he put on the disposable surgical gown he carried in the survey box, put on a hood and gloves, spread a waterproof plastic sheet on the ground, and then carefully laid the body flat and moved it to the open space next to it.
"Let the autopsy begin."
"Someone will help me take photos and fix the evidence, fill in the corpse form and check the records."
Lin Xin subconsciously prepared to start an autopsy.
But Henggou Zhenshu was slightly stunned at this moment, and suddenly reacted from the previous shock:
"Wait, Mr. Lin!"
"What's wrong?" Lin Xinyi stopped in confusion.
I saw this honest and stubborn police officer looking over with a serious face:
"We agreed that you can't do it yourself."
"Mr. Lin, you are still a suspect now!"
"This" Lin Xinyi said with a helpless expression: "Officer Henggou, do you still think I am suspicious?"
"certainly."
Officer Henggou nodded seriously:
"Mr. Lin, you are so strong."
"It fits the characteristics of the murderer very well."
Lin Xinyi: "."
Indeed, if you have the ability to decompress, you have the ability to package and compress it.
There are indeed very few people like him in the world who can compress and decompress a strong man with brute force.
After doing this, he really looks more like a murderer?
"But I've already explained it before."
"If I were a suspect, what would I do to hide the victim in the trunk and then go out of his way to bleed him to attract others' attention?"
"And after killing the person, you didn't drive away quickly, dispose of the body, and then went back to accompany an elementary school girl as if nothing had happened?"
The truth is this.
But Police Officer Henggou analyzed it seriously:
"Maybe. This is a perverted hobby?"
"Some murderers like excitement."
"." Lin Xinyi's mouth twitched when he heard it:
He liked the seriousness of Officer Henggou very much.
The work attitude is excellent and the sense of responsibility is extremely strong.
But this reasoning ability?
Not to mention being on par with the Megure Police Department, at least he was on par with Uncle Maori.
"That's okay." Lin Xinyi sighed softly:
He thought about it and felt that although the other party was stubborn, his request was actually correct.
I have indeed been a leader for a long time, and I tend to do things my own way.
As a suspect, no matter how small the suspicion is, you still have to avoid suspicion.
So Lin Xinyi stood aside very cooperatively and let the local police officers be responsible for the autopsy operation, while he was responsible for observation and guidance.
As soon as the autopsy began, he said straight to the point:
"Actually, I was already confident that I could use the evidence on the body to prove that I was not the murderer. I just subconsciously conducted the autopsy myself."
"Oh?" Officer Henggou looked over in surprise: "Have you found evidence?"
"But Mr. Lin, haven't you started the autopsy yet?"
"No need to test."
"You can see the evidence with your eyes."
Lin Xinyi smiled and asked calmly:
"Officer Henggou, do you know what the murderer used to stuff the deceased into the trunk?"
"It was stuffed in with bare hands."
"Isn't that obvious?"
Henggou enlightenment couldn't help but glance at the corpse:
There were many large light-colored ecchymoses on the body surface.
The light color does not mean that the injury is minor, but because when these bruises were formed, the deceased was already in a dying state with extremely weak vitality response, so the bruises were not congested enough.
Yes, these bruises were the fingerprints the murderer left on his body when he stuffed the deceased into the trunk.
One or two petechiae even retained the distinct shape of the palm.
Therefore, others can guess at a glance that the deceased was stuffed into the small space by the murderer with his bare hands using brute force.
"This is the murderer's handprint."
"and I."
Lin Xinyi stretched out his hand, slowly came closer, and compared the hand-shaped bruises on the corpse.
Officer Henggou can tell from this comparison:
"Mr. Lin's hand is smaller than the murderer's handprint!"
"That's right." Lin Xinyi smiled: "The murderer and I are very different in size."
"This guy wanted to use this body to pour dirty water on me, but he even forgot how big his hands were."
He asked the police officer in charge of the autopsy to carefully measure the overall length of the handprint, the length of his palm, and the length of his fingers with a measuring tape.
"According to the proportional relationship formula that the height is equal to the total length of the handprint × 9.75, the length of the palm print × 17.8, the length of the index finger print × 24.2, and the length of the middle finger print × 21.1, calculated comprehensively"
Regardless of the fact that the murderer was a strange man like Liu Bei with his hands above his knees.
"As long as his body proportions are normal, his height should be at least 1.9 meters."
"This is an extremely large and tall man."
Her hands are so broad and powerful. If she is still a woman, then her future husband must also be a hero.
Lin Xinyi temporarily ruled out this small probability event and portrayed the image of the murderer as a tall and muscular man.
This obviously does not match the figure of Daniel Wu of Tokyo.
His suspicion was suddenly cleared.
"But..." A hint of wisdom flashed in Henggou's eyes: "This cannot rule out the possibility that Mr. Lin has an accomplice, right?"
Lin Xinyi: "."
"My lawyer is Fei Yingli."
"If this happens again, I'll let her speak for me."
"." Henggou Shenwu blushed and closed his mouth.
Yes, Lin Xinyi actually has no need to prove his innocence at all.
Not from the beginning.
The deceased had a grudge against him, and the body was in his car. Does that mean he committed murder?
With a lawyer of Fei Yingli's level defending him, this kind of criminal accusation that doesn't even have complete evidence is simply untenable in court.
"Hug, sorry." Officer Henggou was very embarrassed: "I thought too much."
"It's okay. Until the truth of the case comes to light, the police should always be suspicious of everything."
"It's just that you have to be more trustworthy in your suspicions."
Lin Xinyi casually asked Henggou to comprehend a few words.
Henggou Zhenshu finally stopped using his imagination to interfere with Lin Xinyi's autopsy work.
soon
Under Lin Xinyi's guidance, the body surface examination has already produced results.
And he also discovered some very important clues.
"Judging from the rectal temperature of the deceased, as well as various corpse signs such as rigor mortis, spots, and corneal turbidity."
"The deceased's death time was 1 to 2 hours ago."
Lin Xinyi turned to Henggou Zhenwu and said:
"Officer Henggou, please send someone as soon as possible to investigate the entry and exit records of vehicles entering the hotel's underground parking lot in the past 1 to 2 hours."
Because this underground parking lot is a paid parking lot open to the public, and the hotel itself is of a higher grade, the management is stricter.
So even though there are still no cameras here, at least
All vehicles entering and exiting the parking lot need to be registered.
So as long as you check the vehicle entry and exit records in the parking lot, you will most likely be able to find the license plate number of the car driven by the murderer.
"I see."
After Officer Henggou understood what Lin Xinyi meant, he immediately sent out his manpower to find the parking lot staff to investigate the situation.
But as soon as he "understood" it, he soon became confused again:
"Wait, Mr. Lin."
"How do you know that the murderer drove here?"
"just in case"
"Nothing goes wrong, just trust me." Lin Xinyi's attitude was very firm.
Because he had already learned from Noah's Ark that not long after he drove back to the hotel, Aramaki Yishi's mobile phone number had followed closely and entered the hotel's base station.
And before he drove back, he had just met Aramaki Yoshiichi at the beach.
The two set out almost at the same time and arrived almost at the same time.
The only way Aramaki Yishi could get to this hotel from the sea was by car, just like him.
Aramaki Yiichi had nothing to do, so it was unlikely that he would follow Lin Xinyi by himself.
He probably met the murderer at the beach and was kidnapped by the murderer without saying a word.
And Lin Xinyi had the help of Noah's Ark's communication monitoring technology. He even knew the specific minutes and seconds when Aramaki Yishi's mobile phone entered the hotel.
Just compare this with the vehicle entry and exit records in the hotel parking lot, and you should be able to quickly determine the vehicle in which the murderer and Aramaki Yoshiichi were riding.
"As long as the murderer's license plate number can be determined, there is hope that the murderer's vehicle can be found."
"If we can find the murderer's vehicle, then if we are lucky, we may even be able to find evidence of his kidnapping and murder."
"Oh?" Officer Henggou looked confused when he heard this: "Mr. Lin, you didn't even see the murderer's car, how could you guess that there might be evidence in the car?"
"What evidence? Murder weapon, bloody clothes, gloves?"
"As long as the murderer wasn't stupid, he would have dealt with all of this in time, right?"
Judging from the estimated time of death of Aramaki Yoshihiro, the murderer had killed him at least an hour ago.
This means that from the end of the crime to the present, the hitherto unknown murderer, whose whereabouts are unknown, has at least one hour to escape the scene and process evidence.
Even if there was evidence, by the time the police found the murderer, it would have been completely destroyed by this guy.
But Lin Xinyi looked confident at this time.
It was as if he had determined that there must be evidence in the murderer's car that had not been disposed of.
"Is this it?"
“It’s not ‘certain’, but it’s very likely.”
"Because the evidence I'm looking for is probably something the murderer himself can't even consider."
Lin Xinyi smiled calmly:
Gloves and murder weapons are all physical evidence that the police can think of, and the murderer himself certainly knows that they need to be dealt with.
But the murderer is also a human being, and human wisdom has its limits, and it is impossible to consider everything comprehensively.
Therefore, when police investigate cases, they investigate areas that are difficult for ordinary people to pay attention to.
For example.
"The 'bump' on the deceased's wrist."
Lin Xinyi stretched out his hand and pointed at Aramaki Yoshiichi's wrist:
"Officer Henggou, please guess:"
"What could this red, swollen, and raised bump on the deceased's wrist be?"
"This" Henggou Cenwu got closer and observed carefully.
He quickly came up with the answer:
"Is this a bag from a mosquito bite?"
"That's right." Lin Xin nodded and asked, "Other than that, what else can you see?"
"There was a drop of dried blood near the pimple."
"But there was no injury to the deceased's wrist."
Henggou Shenwu frowned and tried hard to analyze:
"When the deceased was stuck in the trunk, the blood from the wound on his neck did not stain his wrists."
"If it was really stained, there wouldn't be just such a drop of blood."
"Then this drop of blood is."
He thought carefully for a while before giving the answer with a bright eye:
"Is it the blood that mosquitoes sucked out of Aramaki Yoshiichi?"
Mosquitoes will not sit idle after sucking the blood and then vomit the blood back to the victim.
so this means
"That mosquito was killed by Aramaki Giichi while it was sucking blood?"
"That's right!" Lin Xinyi secretly gave him a look of appreciation.
Then he asked: "What else? What else did you think of?"
"This" Henggou was confused for a while when he realized:
With his reasoning ability being evenly matched with Uncle Maori's, seeing this second level was already difficult enough.
There really is nothing more to see.
"Actually, you are very close to the answer."
Lin Xinyi unhurriedly revealed the answer:
"This mosquito is proof."
"If the mosquito was killed by Giichi Aramaki while sucking blood, then the drop of blood on Aramaki's wrist would also contain the mosquito's own body fluids."
"As long as we can find the mosquito's body in the murderer's car, we can compare the DNA of the mosquito in the car with the DNA in the blood on the wrist of the deceased to prove that the deceased had been in the murderer's car!"
The answer he gave was somewhat unexpected.
Henggou Shenwu followed Lin Xinyi's train of thought and thought carefully for a moment, but in the end he just frowned and asked:
"That's not right, Mr. Lin."
"We only know now that Aramaki Yoshiichi killed a mosquito during his lifetime."
"Who knows whether he was bitten by a mosquito in the car, or whether he was bitten by a mosquito at a beach or hotel parking lot before getting on the bus or after getting off the bus?"
Henggou Zhensu was a little puzzled. How could Lin Xinyi be sure that the deceased encountered the mosquito in the murderer's car.
"I'm certainly not 'sure'."
"This is just a conjecture, a bold conjecture."
Lin Xinyi corrected the wording very carefully before explaining:
"The extent of the human body's response to mosquito bites actually depends on the degree of adaptation of the immune system to mosquito toxins."
"When you are bitten by the same type of mosquito for the first time, your immune system doesn't know the toxin yet, so it won't react at all."
"If you are bitten by the same type of mosquito too many times, the immune system will assume that the toxin cannot harm the human body, so it will only react slightly, leaving no pimples on the body, only some inconspicuous little red spots."
"As for the reaction of the deceased, a big red bump swelled up on his wrist."
"It's during the initial adaptation phase of the immune system to these types of toxins."
"By this time the immune system has been exposed to such mosquito toxins and can recognize them and react violently."
"So after being bitten by a mosquito, the human body will immediately experience swelling, accompanied by surrounding redness and swelling, which will reach its peak within 20 minutes."
"After 20 minutes, the swelling will become itchy, hard, smaller, and then slowly subside."
Lin Xinyi first did a little popular science.
The real use of this knowledge is:
He could vaguely deduce the time when the deceased was bitten by mosquitoes by observing the shape of the swelling.
Just like Aramakigi City now.
The bump on his wrist was very swollen and there was a lot of redness and swelling around it.
At this glance, it was clear that Aramaki Giichi was bitten by the mosquito within 20 minutes before his death.
It takes more than 20 minutes to drive from the beach.
Therefore, Aramaki Yishi definitely did not get bitten by mosquitoes at the beach before getting on the bus.
So was he bitten in the parking lot after getting off the car?
"Most likely, not either."
"At that time, Aramaki Yishi had been hijacked and taken to the parking lot."
"The next step for the murderer is to kill Aramaki Giichi and then put him in my car."
"Do you think the murderer would let him get out of the car and move around on his own? Or rather, would he let him get out of the car alive?"
Although there are not many people in this parking lot, it is a public place after all.
And there are cars and pillars everywhere, things that can be used as hiding places and bunkers.
Lin Xinyi assumed the role of the murderer.
He felt that he would secretly kill Aramaki Yichi in the car to prevent him from taking the risk of escaping after getting out of the car.
"Also, Henggou, have you noticed——"
"Where is this bump?"
"Location?" Henggou Shenwu carefully looked at the corpse's wrist: "Isn't it just on the wrist?"
"No, be more specific."
Lin Xinyi smiled slightly and explained:
"We only saw this swelling after opening the cuffs of the deceased during the autopsy."
"In other words, the location of the swelling caused by the mosquito bite is within the coverage of Aramaki Yishi's sleeves."
"What do you mean?" Henggou still didn't understand.
"Mosquitoes are not capable of ripping off people's clothes."
"They generally only bite humans on exposed, unclothed skin."
As he said that, Lin Xinyi once again turned his attention to the body lying flat on the ground:
Aramaki Yoshiichi is wearing a long-sleeved T-shirt today.
Because he was too tall, even this large long-sleeved T-shirt was as tight as a tights.
The cuffs remained tightly attached to his wrists.
Just relying on the strength of that little mosquito, it will definitely not be able to get in.
But on the wrist of the corpse, the swelling caused by the mosquito bite happened to be within the covered area with the cuffs.
"What does this mean?"
Henggou asked nonchalantly:
"The deceased ever rolled up his cuffs himself?"
"This possibility cannot be completely ruled out."
"But I also thought of another possibility:"
Lin Xinyi paused for a moment, then told Henggou Zhenwu:
"You try to lift the deceased's arm and look at it?"
"Okay" Henggou tried it without knowing why:
As the arms were too high, the sleeves that could have tightly covered the entire wrist naturally pulled back and slipped, leaving the smaller half of the wrist exposed.
"As the body position changes, the relative position of the clothes and the body will naturally change."
"As long as you raise your arms, the sleeves will pull back, exposing the wrists that were originally covered by the sleeves."
"This" Henggou Zhenwu was still puzzled: "Isn't this possibility too small?"
"It takes a certain amount of time for mosquitoes to land on you and look for opportunities to bite."
"Who could raise their arms so that their wrists are exposed from the cuffs and keep them still for so long?"
"Of course someone does."
Lin Xinyi smiled and replied:
"Don't you keep your hands on the steering wheel when you drive?"
Henggou hesitated for a while, then suddenly reacted:
"I see!"
"When a person is driving and puts his hands on the steering wheel, his cuffs will naturally slide back."
"So Mr. Lin, you are guessing."
"I guess after the murderer hijacked Aramaki Giichi at the beach, in order to keep an eye on his prey, he sat in the back seat and threatened him with a weapon, leaving Aramaki Giichi to drive."
"It was at this time that he let his wrists hang out of his sleeves and was bitten by mosquitoes on the car."
"If that's the case."
Lin Xinyi's voice also had a hint of expectation:
"Then we are very likely to find the mosquito killed by Aramaki Giichi in the murderer's car!"
By then, whether it is comparing the DNA of mosquitoes or comparing the DNA of human blood in mosquitoes, it will be possible to prove that Aramaki Yoshiichi had been in that car.
Moreover, it can also be proven that Aramaki was in the car shortly after the swelling formed and within 20 minutes before his death.
This can explain a lot of problems.
"Mr. Lin, you are so amazing!"
This was the first time for Henggou Zhenwu to be completely exposed to such a novel method of solving crimes, and he couldn't help but feel a little excited.
"but."
When he was excited, he suddenly remembered:
“Can mosquito DNA also be used for comparison?”
"Is it also possible to extract human blood from mosquitoes for identification?"
"sure."
Lin Xinyi ignored the subtle gaze of Miss Haiyuan beside him.
His face was filled with the confident smile of an academic master:
"It's just a matter of two papers."
