Chapter 43: Forensic Doctor Lin, have we been fooled?
Could it be that the police's judgment was biased?
Feng Charlie thought about it and asked the police officers to secure the evidence while the others searched the victim's room together to make sure that there were no other clues except the envelope.
Then he left and returned to the serious crime team.
Lin Meiqi walked into the autopsy room, where the victim Tao Daye's body was neatly prepared and placed on the autopsy table.
Normally at this time, police officers would avoid coming in to avoid seeing the bloody autopsy scene.
Instead, Xie Zhiruo knocked on the door and asked Lin Meiqi, "Forensic Doctor Lin, do you need my help?"
Lin Meiqi looked at the tools beside her and took out a pair of bone pliers and tweezers. She said, "No, if you want to learn, just watch from the side."
Xie Zhiruo nodded and swallowed.
This was the first time she had seen a dissection so close since she started studying with Lin Meiqi. Fear was stuck in her throat, but she still stood by and tried to remain calm.
After Lin Meiqi used tools to dissect the corpse, she quickly put the tissue slices into the instrument for operation.
Xie Zhiruo looked at these steps and silently took out a notebook from her pocket to record them.
Lin Meiqi asked her, "Aren't you afraid when you look at me like this?"
"fine."
"In fact, you just need to understand it. As a criminal police officer, forensic science is just an auxiliary to you."
"No, forensic medicine is so useful! For example, if the victim this time, Tao Daye, died from a stab wound to the heart, then the murderer is the same person as in the previous two cases; if he died from a congestion in the brain caused by a blow, then the murderer is completely different..."
Lin Meiqi looked at her, very pleased: "That's good, but the results won't be out for a while, at least we have to wait until the afternoon. When the report is out, I will take it to the office."
Xie Zhiruo nodded and left the autopsy room.
Lin Meiqi took off her clothes after the autopsy last night, cleaned her hands, and returned to the forensic doctor's office.
Just then, Liang Yifeng came to deliver pork chop rice.
Lin Meiqi looked up at her. Liang Yifeng looked apologetic. He opened the pork chop rice and placed it in front of Lin Meiqi: "Forensic Doctor Lin."
"What's wrong?"
"Do you remember this pork chop rice? Forensic Doctor Lin, I bought it for you when you first came here..."
He paused and cleared his throat, as if he had something to say, "Well, um, Forensic Doctor Lin, I've told Sergeant Zhan that I'm going on a blind date this weekend."
Lin Meiqi's eyes lit up: "Really? That's great, I look forward to you bringing back a girlfriend!"
"Thank you. I'll be out now, Forensic Doctor Lin."
Lin Meiqi nodded and Liang Yifeng walked out.
Thinking about Liang Yifeng's actions, Lin Meiqi thought that the issue between her and Liang Yifeng should be over.
The relationship between the two returned to the time when they bought pork chop rice. At that time, Liang Yifeng was a fan of the original owner, and that was all.
The corners of Lin Meiqi's lips curled up slightly in a smile.
I can finally treat him normally from now on.
She recalled that during her first days of school, after watching the dissection scenes, she was the only one among her classmates who could still eat normally. The other students had lost their appetites, and some even went out to vomit. So I just finished the dissection and now I am still calm while looking at the pork chop rice.
She picked up the spoon and scooped a spoonful of pork chop rice. The pork chop sauce wrapped around the rice and the aroma of the meat spread in her mouth.
She couldn't help but let out a "hmm" sound, it was so delicious! No matter how many times I eat this pork chop rice, I am always amazed.
As Lin Meiqi was thinking this, she heard some noise outside.
She stood up and looked outside. It was the thin man A Luo who was caught by Feng Charlie.
Lin Meiqi stood at the forensic doctor's door and looked at him.
A Luo passed her and entered the interrogation room.
During this time, he glanced in the direction of Lin Meiqi, as if he had grabbed a life-saving straw, and suddenly stopped where he was, and refused to move despite being pushed by the police behind him.
He just looked at Lin Meiqi expectantly, his voice hoarse: "Forensic Doctor Lin, please help me! It's really not me who killed Tao Daye! I didn't kill anyone at all. I don't even know his address. How could I kill someone?"
Lin Meiqi walked forward and signaled the police officer to take A Luo to the spot.
She frowned, feeling that something was wrong, and asked, "If you don't know his home address, you can also wait in the place where he often appears, and then attack him with a stick when he appears!"
"No, I don't know anything. I didn't hit him with an iron rod. I didn't leave the house yesterday!"
"Is there anyone who can prove that you were at home and hadn't been anywhere?"
"No, I didn't contact anyone, nor did I ask anyone to come to my house. But, I really didn't do anything! Didn't I just complain to you police last time? Why is this happening? I said I couldn't find his address and asked the police to help me find it, but you didn't tell me where he was! So there's no way I could go find him! Forensic Doctor Lin, can you please make it clear during the autopsy whether there are any traces of me on his body? I really didn't touch him!"
Lin Meiqi hummed: "Don't worry, if it wasn't you, we would definitely not wrongly accuse a good person."
"I, I feel so wronged. The murderer killed him, but I have to bear the blame myself..."
As A Luo covered his face in pain, he still had handcuffs on his wrists.
The police officer behind asked Lin Meiqi: "Forensic Doctor Lin, can I take him away?"
"Let's go!"
"Forensic Doctor Lin, you must find the real murderer and clear me of suspicion!"
Lin Meiqi returned to the forensic room and sat thinking.
Xie Zhiruo walked in and asked curiously, "Forensic Doctor Lin, is it really not Ah □□'s fault this time?"
Lin Meiqi looked at Xie Zhiruo, also a little depressed: "He shouldn't lie. He went directly to the serious crime team to compete with the police and wanted to find the previous bully for revenge. Why didn't he admit it when he really did it? Unless it really wasn't him, that is, the iron rod hitting the victim's back was someone else. Maybe there is something overlooked at the scene. No, it's not the scene."
"Where is that?"
"He was probably hit somewhere else, outside his home. But later, the victim, Tao Daye, did not go to the hospital but returned home. He might have felt that the injury was not serious, or there was something more important that required him to go home, such as an appointment and he wanted to meet that person before leaving. As a result..."
"So the attacker is probably not at home, but outside. In that case, who else could it be besides A Luo?"
"During the visit, there was not a single one of Tao Daye's neighbors who didn't dislike him. He had offended too many people. I thought maybe someone had done it on impulse. In that case, the sergeant would have to lead a new investigation."
Xie Zhiruo propped up her chin: "Doesn't that mean he has a lot of work to do?"
"If I can find fingerprints on Tao Daye's back, it will be easy. I just need to find someone to compare it with," said Lin Meiqi.
A Luo's interrogation began, and Charlie Feng entered the interrogation room after finishing his work.
Lin Meiqi and Xie Zhiruo left the forensic room and also listened by the monitor.
A Luo cried and said that he had not had the chance to kill anyone, but why was he labeled as a suspect?
"So, you really thought about killing Tao Daye?"
"Yeah, such a scum will only cause trouble to others if she lives. It's better for me to deal with her myself! I just regret that I didn't find him first!"
Feng Charlie and the police officer who was interrogating him looked at each other and couldn't help but sigh: "You are too extreme..."
…
The interrogation lasted for two hours. Luo explained what he did on the day of the incident and whether he had contacted anyone outside of his home. Feng Charlie had to send police officers to verify all of this.
There was a breakthrough in identifying the murderer in the campus case. This time, the important threatening letter was found. However, a sudden accident happened and the matter was disrupted by A Luo.
The two things are intertwined and complicated.
However, Charlie Feng suddenly thought of something and changed the subject, asking A Luo: "Do you remember any other vicious incidents that happened in Hong Kong and Kowloon Middle School that were finally suppressed? And this person should be related to Tao Daye. Was he involved?"
A Luo thought for a long time and said, "Yes!"
"Hurry up and tell me."
"Tao Daye beating me is not a vicious incident? Tao Daye has bullied so many people, there must be someone who was seriously injured by him, but he is the principal's nephew, this matter is impossible to be reported to the outside world, many people pay a sum of money to settle privately, and then suppress it. Otherwise, the evaluation will not be good if you transfer to another school. If you want to transfer, it will be troublesome to detain the procedures!"
It turns out that after all these twists and turns, it finally comes back to A Luo himself.
Feng Charlie was speechless for a moment.
In the afternoon, the results from Lin Meiqi came out.
She looked at the report, and sure enough, just as A Luo had said, there were no fingerprints of his on the back from being hit with an iron rod, but instead there were fingerprints of other people who had been beaten and some clothing fibers.
Lin Meiqi took the results to find Charlie Feng and said, "It should be someone who had a grudge against Tao Daye and suddenly got the idea. Luo is not suspected of murder. This fiber comes from a simple woven bag, which may be used to carry goods. Let's see if anyone in his neighbor's house has this kind of bag. Maybe they wanted to put the bag over his head and beat him at the same time, but he escaped. Also, the congestion happened very quickly. Tao Daye couldn't have rushed here from too far away. It probably happened at the doorstep, otherwise the pain would be unbearable and he would have to go to the hospital at that time."
Feng Charlie nodded: "Anything else?"
Lin Meiqi was listening to the movement of the instruments in the forensic room, and suddenly there was a "ding" sound.
She hurried over and took a look at the analyzed data: "The cause of death is out! The victim, Tao Daye, was still stabbed in the chest with a sharp knife and died. The beating with a stick injured his cervical vertebrae, causing dislocation, but the suspect does not constitute murder."
"good!"
Feng Charlie stood up and left with the police officers. He wanted to find any traces of the attacker.
Lin Meiqi was concentrating on searching the fingerprints on the envelope to see if there were any other clues mixed in.
The fingerprints extracted so far are basically those of the victim, but half of the fingerprint is of unknown origin. When compared with the victim's fingerprint from all angles, they do not match.
If the victim is excluded, then it is very likely from the murderer.
The result of the half fingerprint came out that night. Lin Meiqi was very excited when she got the result. She took it to Feng Charlie and said, "Sergeant, it can be confirmed that this is a fingerprint different from the victim's. It belongs to a woman. Now we just need to search the school library and we should be able to find out who this fingerprint came from!"
Charlie Feng also said excitedly: "Okay, I'll stay here with you tonight until the results come out."
It takes time to re-do the fingerprint test, especially for the Curry comparison, which requires Lin Meiqi to apply for fingerprint information online.
However, as time goes by, it may not be so complete. It is also possible that there are omissions when entering fingerprints, but you can only take a chance.
If it is really possible to find that person, at least the clues will be cleared up and most of them will be solved.
While waiting for the results, Lin Meiqi felt a little sleepy.
Seeing that it was getting late, already ten o'clock in the evening, he fell asleep on the forensic table.
Feng Charlie was about to go in and ask if the results were out, but he saw a blue light coming from the instrument next to him. He probably had to wait for a while, and Lin Meiqi fell asleep.
This won’t work, you’ll catch a cold.
Without thinking, he walked forward, took off his coat and put it on Lin Meiqi.
Except for Feng Charlie, the last police officer in the office also left, leaving Feng Charlie alone.
The lights were half dim, casting a dim light over him, the clock made a ticking sound, and the surroundings seemed even quieter.
Feng Charlie folded his arms and looked out the window at the darkening sky. After a while, he fell asleep too.
Two hours passed in this sleep.
When Lin Meiqi woke up, she yawned and stretched. She walked forward and adjusted the instrument parameters. Then she looked at the comparison results and saw a string of identity numbers marked next to the photovoltaic!
This means that the student does exist in the fingerprint database!
This is thanks to the Hong Kong and Kowloon Middle School, which once used the most advanced method at the time to record fingerprints during a physical examination, so that the fingerprints were preserved in the hospital library for many years.
The member information in the fingerprint database is incomplete, but it happens to include that of the suspect, which is a blessing in disguise.
Lin Meiqi copied down the identity key from the fingerprint database and entered another police system to transfer the information.
The name corresponding to this identity key is a rather unfamiliar name, Li Meimei.
With this name in mind, Lin Meiqi got up and went to look for Feng Charlie, who had fallen asleep in a chair with his arms folded.
Lin Meiqi reached out and patted his shoulder. Feng Charlie woke up, glanced at Lin Meiqi, and asked, "The results are out, how are they?"
"We have information about the suspect."
"Really? That's great!"
Feng Charlie didn't expect it to be so smooth, but he took a look at the name and fell into deep thought: "It's not in any of the classes of the victims, nor in the same grade."
"He should be a senior student, three years older than the victims."
"Your identity information is out. Your mission is complete. Go back and rest!"
"What about you, Sergeant? You're not going out on a mission to arrest people so late at night, are you?"
"No, as long as the suspect hasn't left Hong Kong, there's still time to act tomorrow morning. Besides, we need to first find out her current home address."
Seeing that the murderer is about to be revealed, I can finally have a good sleep when I go back home today.
Since Feng Charlie said so, there was no need for her to stay any longer.
After Lin Meiqi said goodbye to Feng Charlie, she saw Feng Charlie as soon as she walked downstairs.
"If you stay up late in the forensic laboratory at night, it's best to wear something thicker. It's almost autumn, and it's already chilly in the early morning."
Lin Meiqi raised her head and whispered, "Thank you for the reminder, Sergeant."
Feng Charlie said, "Why are you being so polite to me? Come on, get in the car, I'll take you home."
"Isn't this a bad idea? I can ride my bike very fast by myself. Now there are no cars or people on the road, so the road is smooth." said Lin Meiqi.
Charlie Feng insisted, “No, from now on, whenever we work overtime, I will be responsible for your safety.”
Lin Meiqi had no choice but to follow Feng Charlie to the car.
Feng Charlie opened the passenger door for her and Lin Meiqi got in.
Lin Meiqi, who was originally excited about collecting the suspect's fingerprints, suddenly thought about something and felt something was wrong.
She asked Charlie Feng: "The clues of this case were so confusing before, and we got very little information. Even the victim himself was unwilling to reveal what happened ten years ago, so we kept hitting a wall when we asked him. But when the third victim's letter was not taken away, the murderer had already entered the house and killed people. Could it be that he didn't have time to find the certificate in the book, or was the letter deliberately left for the police?"
Feng Charlie thought for a moment and said, "If there are a lot of books in the bookcase at home, maybe the murderer couldn't find a place to destroy the evidence..."
"But think about it, why did the first victim, Hu Panshan, take the letter and briefcase out of the house on his own? Even his wife didn't know about it. It was because the letter contained evidence that he had killed someone ten years ago. Although I don't know how the school suppressed this matter and we didn't find out about it at all, we shouldn't have kept that letter at home!"
Feng Charlie thought thoughtfully: "If what you said is found out, what they did in the past will be exposed."
"Yes, the second victim, Liu Yuyu, was also hesitant when questioned by the police. If someone who knows the whole story pretends to be that person and sends them a warning and threatening letter, then if they call the police and their previous murder is proven, they will also be brought to justice. So their first reaction after receiving this letter should be to destroy it. It seems a bit strange to keep it at home."
"Is it possible that Tao Daye is simply not cautious in his conduct?"
"Maybe, but we can't rule out other possibilities. What I fear most is that we were tricked into this whole case. I don't know why, but I always have this vague feeling. For example, were the eyewitnesses in the first case set up? Otherwise, why would the murderer that everyone witnessed have an alibi? And the evidence is so conclusive. Is it possible that we were tricked?"
Feng Charlie originally had some doubts about these cases, and after hearing what Lin Meiqi said, a chill ran down his spine.
"What you said is possible. Why was the murderer so meticulous and calm that he was able to disguise himself as Qin Roumei and escape tracking in advance, but this time he left half a fingerprint on this letter? Perhaps he was guiding the police in the direction he wanted us to go. But he thought the police were freeloaders and couldn't see his little thoughts?" Feng Charlie raised his eyebrows.
"Perhaps the murderer thought this was a perfect crime, or that we had no way of convicting him. He is indeed a confident, even a little arrogant guy. But I think things are speeding up. Now that he has revealed the fingerprints to us, it means that the scene he wants us to see will soon be revealed to us."
Whoosh, a cold wind blew by.
The temperature has dropped a bit in the past two days, and it feels cold when the wind is strong at night.
Lin Meiqi shivered in the car, and Feng Charlie picked up the coat from the back seat and handed it to her: "Put it on, don't catch a cold." "I'm fine, I'll be home soon. Go home and get into the warm bed. At worst, I'll make another bowl of ginger soup."
Soon, the car arrived. Feng Charlie parked the car downstairs, opened the door and sent Lin Meiqi downstairs.
I watched her go upstairs and turn on the lights in the house. I watched her for a while before returning to the car.
Before leaving, Feng Charlie had already told Lin Meiqi that she didn't need to come so early tomorrow as she had been busy until the early morning. It would be okay even if she went to the serious crime squad tomorrow afternoon as the rest of the matter would be left to the police officers on field duty to carry out the arrest.
Lin Meiqi said, "Okay, but Sergeant, you have to be careful to prevent any sudden changes at the scene."
It was already late at night. Lin Meiqi looked down through the window and saw a figure in the dark get into the car, stop downstairs for a while, and then quickly turn around and leave.
Lin Meiqi was so tired that night that she fell asleep as soon as she touched the pillow. When she woke up, it was already noon.
She went downstairs to buy two buns, and drank them with the shrimp porridge. She felt warm all over.
"Fortunately, I didn't catch a cold yesterday. I feel much better after a good night's sleep."
After lunch, you can go to work. Riding a bicycle is a good exercise to help digestion.
Lin Meiqi found that she had been riding a bicycle more recently, and her calf muscles looked very strong. When she touched them, they were hard.
If I encounter a criminal next time, with the help of my physical strength, I will probably kick him like an iron rod with a "bang", making it impossible for him to escape.
As she was thinking this, the phone suddenly rang.
Who called? Lin Meiqi was stunned for a moment, then stood up to answer the phone without finishing chewing the bun in her mouth.
It was Charlie Feng's voice on the other end of the line: "Forensic Doctor Lin, I'm sorry to bother you with your sleep. Actually, you should have rested more. I kept you busy so late yesterday."
"It's okay." Lin Meiqi said.
"There is an emergency right now and I have to ask you to come over."
"Did you find the suspect's residence?"
"That's right. The so-called murderer Li Meimei, whose fingerprints were found, died at her home. The way she died this time was different from the previous three. There were no bloody scratches or signs of her skin being cut open. It looked like suicide."
When Lin Meiqi heard this, her heart sank. As expected, the whole trap was about to entangle the police.
She had a guess that the so-called "suicide" might be to create such an illusion, to divert the suspicion of the first three victims to the so-called murderer, and then wait for the police to come and convict her?
Such a closed loop is formed, and the murderer can escape.
However, this is still Lin Meiqi's subjective judgment. Only when we arrive at the scene can we know whether there are any loopholes in this so-called suicide case.
If there are no flaws, even if she feels that something is wrong, without a chain of evidence, the truth of these murders will probably be buried in the sea.
