Hunting Forensic Medicine 2 Unsolved Case Team

Tang Zhexue would definitely not say thank you to the suspect, and he guessed Lin Dong would not either.No matter how you put it, it's five human lives. How cruel must this person be to do such a frenzied thing?

He has never been in contact with the suspects in serial murder cases, after all, not many people have the guts to kill, and the common sense of killing for life is common, even for people who don't know the law.Last year, there were 832 criminal cases in his branch, including theft of property, guns and drugs, kidnapping and extortion, and only two cases resulted in the death of the victims.One is the one where the flight attendant was killed, and the other is where one of the neighbors was stabbed to death in a neighborhood conflict.

In the final analysis, these two cases were crimes of passion, and the suspects in the chaos at the scene were clear.As for the murderer who made the "bloody fingerprints", he had a very meticulous crime plan.When encountering this suspect, even if he is caught, inference alone is not enough for the procuratorate to prosecute, there must be a complete and closed chain of evidence.

However, there were not even a single fingerprint at the scene, but a few shoe prints were extracted.According to the technical appraisal report at the time, it was suggested that the murderer may have put shoe covers or socks on the soles, which led to a large deviation in the inference of the murderer's height and weight.

Now it is inferred that this person is a doctor, then everything makes sense: understanding the structure of the human body, wearing gloves and shoe covers when committing crimes, and cleaning up the evidence left at the scene before leaving are all professional qualities; Open up to yourself, hold personal information about victims who don't even know each other.

While driving, Tang Zhexue muttered, "Such a smart person, what's wrong with killing people?".

"It may be that the murderer has experienced similar incidents, and people close to him paid the price for it, which caused a psychological shadow." Lin Dong said with a soft sigh, "I investigated a case before, and the wife killed her husband. The murder weapon was a hammer, and she beat her husband more than 70 times while she was asleep... During the interrogation, she told me that she would have no chance of survival if she didn't kill the man... The child was only eight years old, a girl, and she kept crying and saying, 'Uncle, don't Catch mom, dad wants to beat me, she killed dad to protect me'..."

Those who heard it were sad, and Tang Zhexue gave a "tsk" sound that didn't make sense, "No wonder my dad said he would not let me engage in criminal investigation. If I see too many cases like this, I will have a fucking psychological shadow."

"If you watch too much, you will become numb." Lin Dong took off his glasses, took out a handkerchief from his pocket and wiped it lightly, "The legal principle is always greater than the rationale, such wives are not rare in women's prisons, I wrote an article For related papers, more than 300 witness statements have been collected. Among these people are urban intellectuals and rural housewives, ranging in age from their early twenties to their mid-fifties. Only a small number of them have sought legal help, and most of them choose to swallow their anger , until it becomes unbearable and eventually leads to tragedy.”

"Why?" Tang Zhexue couldn't figure it out.

"Some are for the sake of their children, some are limited by financial means, some simply don't know how to seek help, and some are influenced by the atmosphere of their original families. It seems that it is only natural for men to beat their wives and parents to beat their children."

"My dad never hit me."

"Then you were good enough when you were young."

"No, he just doesn't have time to talk to me." Tang Zhexue sneered, "My mother hit me once, she used to play volleyball, and that hand hit her ass, damn it, it hurts me for a week. Sit on the corner of the stool."

Lin Dong asked, "What did you do?"

Tang Zhexue was a little embarrassed at once: "Smoking my dad's cigarette secretly, I couldn't find a lighter, so I turned on the stove, turned it on and forgot to turn it off, and almost ordered it for my family."

Lin Dong frowned: "How old are you?"

"Ten years old, or my mother will slap you to death." Thinking of the feeling of that slap, Tang Zhexue subconsciously shifted his sitting position, "She said, when you turn eighteen, if you want to smoke, it's your own I don't care about the choice, before that you have to let me see you smoking a cigarette again, I'll smoke you to death, you little bastard!"

Lin Dong sighed with a smile: "Your mother is really a hero among girls, and her education concept is also very avant-garde."

"Marrying a man like my dad, I really can't live without a little courage..." Tang Zhexue pressed the car window to disperse the smoke, "When I was in the second year of junior high, my dad... They have offended people by engaging in anti-gang activities, and the door of the house was sprayed with red paint. At first glance, it looked like blood. My mother didn't say anything when she saw it. Later, when my ex-girlfriend broke up with me, I thought about it, and if we split up, we will split up, and it will be a burden to others if this kind of life is shared."

"You really think about it."

"What can you do if you can't think about it? Kneel down and beg for a change of heart? I can't do that."

"Girls are meant to be coaxed..."

Tang Zhe let out a puff of smoke with a smile, turned his head and glanced at Lin Dong quickly: "Team leader, you know women so well, why haven't you gotten married yet?"

Lin Dong lowered his eyes and said in silence for a moment, "I don't dare to be emotional. If I do, I will die."

The fingers on the steering wheel tightened slightly, and Tang Zhexue aimed at Lin Dong from the corner of his eye.The side face looked a little lonely, as if caught in painful memories.

——Hey, it seems that my team leader has been severely hurt.

------------

Since the family members of the victims in the second, third and fourth incidents had moved out of their original residence and changed their contact information, they had to go to the home of the fifth victim to inquire first.

The fifth victim was a 16-year-old boy named Yan Yujie.Hanged to death from the water pipe in his bathroom.If it weren't for the bloody handprints on the frosted glass, it would have been a complete suicide scene.

The building in his house looks like an earthquake-resistant building built after the 40 earthquake. The building is more than [-] years old and is currently facing demolition. There are big "demolition" characters everywhere outside the building.The road is narrow and illegally built, too many cars are not easy to park. Tang Zhexue drove the car around several times before he found a space where he might be stuck with illegal parking stickers.

Yan Yujie lived on the fifth floor. When Tang Zhe went upstairs, he found that most of the residents in the building had moved out, the building was about to be demolished, and the light bulb was broken and no one was repairing it. The corridor seemed depressing and cramped.It was Yan Yujie's father who came to open the door. He was over sixty years old and had gray hair all over his head.They had already contacted the other party on the way here, and it was he who answered the phone.

The house was a mess, with packed and unpacked stuff piled up everywhere, with almost no place to step down.Yan's father didn't ask them to sit down either. Firstly, there was really no place to sit in the house, and secondly, he was very disappointed in the police. He hadn't been able to give his son justice for 20 years.

He lit a cigarette by himself, stood by the kitchen door and flicked ash on the floor while complaining: "I thought no one would check anymore, my son just died for nothing."

Tang Zhe didn't agree with each other.In the interrogation recordings he had heard, this father Yan kept asking the investigators questions such as "Can the other party compensate the murderer after finding the murderer", which means that people are dead anyway, so they can't support them for so many years. Bar?

He really felt that it was because of such a father that he raised a bastard son who bullied others.

"No matter how many years have passed, the police will definitely investigate the cases that should be investigated." Lin Dong has seen all kinds of family members of the victims, and Yan's father is not the best in his opinion. Your son's actions resulted in the need for medical attention?"

Yan's father's two small eyes were immediately filled with displeasure, and his tone became impatient: "Hey! It was my son who died! Why do you blame him instead?"

Lin Dong said calmly: "I don't mean to blame your son, but this may be the reason why he was killed, so we must investigate clearly."

"Isn't it common for children to fight and fight? Can you kill people for this?" Yan's father snorted disdainfully, "You have been investigating for 20 years, and you have come to such a conclusion, heh, the police are really good."

"Do you want to find out who killed your son?"

Tang Zhe was rubbed up immediately after learning this fire, and he was taller than him, and pressed in front of Yan's father, forcing him back into the kitchen in a daze.What he saw in front of him made Lin Dong completely understand Captain Shi's intention of sending Tang Zhexue here. Indeed, this young man is a bit anxious.

I still have to grind, I am afraid that I will have to fight with someone who is so dirty and messy.

He stretched out his hand and pulled Tang Zhexue away, and continued between the two of them: "This is the direction of suspicion. We have to track down any clues to the end. According to the inquiries of Yan Yujie's classmate and teacher, he was in the school. He is not peaceful, and some classmates are even bullied by him to the point of transferring to another school. As for what he usually does, I think you know it well."

"...I... I don't know what he did, the teacher always contacted his mother for anything..." Yan's father stammered, "After the divorce, the child belongs to me... His mother doesn't care... ...I'm busy with work, I don't see the sky, and I really don't know what the children are doing at school."

"I'm not questioning your tutoring, I just want to know if Yan Yujie ever sent a classmate to the hospital."

Father Yan frowned and thought about it carefully, and said: "...It seems that a child had a nosebleed or something... At first he said it was my son who hit him, but he later admitted that he fell it himself."

"Which hospital did you go to?" Lin Dong asked.During the interrogation, no information can be provided to induce witnesses to answer from their own memory.

Yan's father frowned even tighter: "The damn thing is handled...it should be the No. [-] Hospital, it's on the street next to my son's school."

Lin Dong demanded: "Please, please contact your ex-wife to confirm."

Father Yan didn't seem very happy, but he looked up and saw Tang Zhexue staring at him with two big black and white eyes, so he had to take out his mobile phone and dial the number of his ex-wife, and turned on the speakerphone under Lin Dong's signal. .

"I went to the No. [-] Hospital for emergency treatment that day. You hid, and I was almost torn apart by my parents!"

Hearing Yan's mother complaining full of resentment after many years, Lin Dong turned around and exchanged glances with Tang Zhexue.

OK, right on.

------------

The direction of investigation has been established, but to find out the receiving doctor from the records of 20 years ago, it is basically tantamount to finding a needle in a haystack.It is impossible to investigate all the doctors who worked in the emergency department of the First Hospital at that time, and we must continue to identify the characteristics of the suspects and narrow the scope of the investigation.

After working for two days and one night without sleep, Tang Zhexue went back to the bureau to get a camp bed first, put one in the room, and said to Lin Dong, "I will sleep for half an hour, team leader", set the alarm clock on the mobile phone, lay down and fell asleep .

He also said that the unsolved case team is not busy, and it feels less relaxed than being in the criminal investigation detachment of the sub-bureau.

Putting the coat on for Tang Zhexue, Lin Dong turned around and walked to the whiteboard for case analysis, picked up a marker pen and dragged a line from the question mark, and wrote the words "characteristics of the suspect" at the end.After a short pause, he began to write in a swish.

Half an hour later, the alarm clock rang suddenly.Tang Zhe sat up after a while, struggled with drowsiness, and then yawned and called Lin Dong: "Team leader...you can sleep for a while..."

Lin Dong didn't speak, his eyes were fixed on the handwriting he wrote on the whiteboard.After Tang Zhexue put his coat back on the door, he went to Lin Dong's side to read what he wrote.There are several small question marks besides the big question mark, and there are notes after each question mark.

He saw Lin Dong put a question mark behind Yan Yujie's name with a red pen, without any remarks.

"What does this mean, team leader?" He asked Lin Dong.

Lin Dong put down the marker pen, closed his arms and crossed his arms and said, "I can't figure out why the murderer stopped after killing Yan Yujie. According to his crime frequency and murderous impulse, he shouldn't stop here."

"Strictly check..." Tang Zhexue scratched the back of his head, his tone uncertain, "Didn't Captain Li say that the whole city was about to be under martial law at that time?"

Lin Dong shook his head.

"No, killing a serial killer is just like an addict taking a drug. No matter how strong the external pressure is, it's hard to say stop."

Now Tang Zhexue also fell into deep thought.Human behavior has rules to follow, determined by habits and ways of thinking.What Lin Dong said was right, it was really unreasonable for a murderer who killed five people in half a year to stop suddenly.

"Are you arrested?" He asked again.Generally speaking, if a recidivist suddenly disappears, it is very likely that he was arrested for other things, which restricts his personal freedom.

Lin Dong denied it: "It's unlikely. He acted cautiously and thoughtfully. He killed five people without leaving any flaws. He shouldn't make mistakes on other issues."

"Then..." Tang Zhexue cast his eyes on the whiteboard, sorted out what Lin Dong had written from the beginning, and muttered while reading, "The behavior of the first victim is the incentive for the murderer to start killing. experience... the middle ones were all uncontrollable impulses, and the last minor..."

The word "underage" suddenly gave Lin Dong an idea. He patted Tang Zhexue's arm and said, "The murderer was about the same age as Yan Yujie when he experienced the tragic incident. To the murderer, killing Yan Yujie is not easy." It is equivalent to killing myself back then, and all the pain is over."
