The Rise of the Peninsula

213 Chapter 0176 – The Case Strikes
After hearing this, Pu Shangyuan didn't speak, but hung a tendon in mid-air with his hands, then took out a lighter from his pocket, and burned the tendon fiercely. When the blue smoke came out, he hurriedly put the tendons in front of my and Qiu Xiumin's noses, and said:
"Smell it."

After I heard it, I took a deep breath, and Qiu Xiumin also stretched her neck and sniffed it.

"Did you smell any special smell?" Park Shangyuan put down his chopsticks and said.

"No." Qiu Xiumin and I shook our heads tacitly.

"If it was speculation just now, then this is substantial evidence. Beef tendon is a high-protein food, and the protein content in it is relatively high. You should have learned it in high school chemistry class. During the burning process, protein will emit There is a smell of burnt feathers, but this beef tendon does not, which is enough to show that this large plate of beef tendons is fake and shoddy." Pu Shangyuan picked up his plate and walked back to his seat.

"I'm sorry everyone, you can eat other dishes first, and I'll ask the boss to come over and fix it later." In this private room, besides the five of us, there is another person, that is the waiter in the private room.She has been standing at the door of the private room since we started eating until now, without moving.At this moment, I could read the surprise and panic on her face. It is estimated that the actions of the few of us really shocked the waiter.

We were full of food and drink, and when we settled the bill, the boss was very sorry to waive the entire meal, and promised us that similar situations would not happen again in the future.Seeing the boss's sincere attitude, we held the mentality of "forgive others and forgive others", so we did not report him.Although we are all law enforcement officers, we can't be impersonal, don't you think?
"I finally understand the meaning of the phrase 'knowledge is money'." Dian Wei said with a smile standing at the door of the restaurant with a toothpick in his mouth.

"I heard from the seniors in the Prosecutor's Office that you are all strange people in the corpse investigation department, as expected. Fortunately, Director Leng put me in the same office as you, a fairly normal person." Qiu Xiumin said from the beginning Float behind to my ear.

Pu Shangyuan turned around suddenly, pointed at the tip of her nose, and said in surprise: "What? You share an office with me? Doesn't your unit have vacant rooms?"

Before I could finish my grievances, Dian Wei hugged me into the car and said with a smile:

"This was arranged by the higher-ups. You kid is so cheap that you are a good boy."

"What did I take advantage of?" Pu Shangyuan shook Dianwei's shoulders away with some resentment, and plunged into the car.

How did we know that the joy of reunion has not completely dissipated in my mind, and a "time bomb" has entered a countdown state.

At noon the next day, in the family area of ​​Seoul Medical University, two women and a man were sitting around a dining table having lunch.

"Sister Wu, today's soup is a bit salty." A woman in her 30s complained to an old woman in her 50s sitting next to her.

"Then I'll add some water and boil it again." The woman called Sister Wu hurriedly picked up the soup basin and was about to walk into the kitchen.

"Sister Wu, put it down, just pay attention next time, there is no need to re-burn it." The man sitting beside him eating rice said.

"How do you drink this soup without reheating it?" The woman yelled at the man with some reluctance.

"If you don't drink a meal, you won't die." The man put the bowl and chopsticks on the table, stretched his face, and said angrily to the woman.

"How did you talk?" The woman stood up, pinching her waist with her hands and yelling at the man.

The man looked up at the unreasonable woman, threw the bowl and chopsticks away, got up and walked towards the door.

"Why are you going?" the woman shouted at the man's back.

"Don't eat, go to the laboratory."

Boom!After the man finished speaking, he closed the door with all his strength and walked away, leaving the distraught woman in the house.

At five o'clock in the afternoon, just as I was planning to have a good talk with my father at night, the "death call" in the duty room rang.The reason why it is called the "death phone" is because this phone is the alarm number of our department, and no one will call it at ordinary times. Only when a homicide occurs, the phone will ring.

"It's over!" I heard the phone ring and realized something was wrong.

Dian Wei rushed to the phone, quickly picked up the receiver, and then he replied to the phone with a solemn expression:
"Okay, I see, I'll be right there."

"Is there a case?" Pu Shangyuan looked at Dian Wei's serious expression and asked quickly.

"A female corpse was found in the family building of the medical department. Hurry up and call Park Shangyuan and the others." After Dian Wei finished speaking, he quickly ran into his office to prepare his camera equipment.

Park Shangyuan didn't dare to be negligent when he heard the words, he turned around and ran up to the second floor, and after a brief message, he returned to his office to prepare his equipment.

Bang, I pushed the door of the office open. Seeing me in a panic, Qiu Xiumin got up from the sofa and asked my busy back, "Is there a case?"

"Yes, there's a murder case, hurry up and help!" I said without turning my head.

"After holding back for a month, there is finally a case!" Qiu Xiumin said excitedly.

Hearing her words, Pu Shangyuan looked at her excited expression strangely, and said viciously: "You soy saucer, you are not afraid of flashing your tongue." After speaking, Pu Shangyuan picked up the investigation box and ran out of the door quickly.

"Wait for me!" Qiu Xiumin stepped on those police high heels and chased after her.

Twenty minutes later, the five of us arrived at the scene of the crime. The surrounding areas of the scene were protected by the police from the local police station, and Xu Shi, the head of the criminal police team, was also standing among the crowd.

When Pu Shangyuan got out of the car, he trotted over.

"Captain Xu, what's the situation at the scene?" Park Shangyuan stepped forward and asked.

"According to the preliminary investigation, the name of the deceased was Xu Wanyi, female, 34 years old, a doctor at the No. 1 civilian hospital in our city. Her husband was a professor at this medical university, named Liu Jianliang, 54 years old. The deceased was Liu Jianliang's second son. Wife, the two of them have no children together, usually only the couple and a nanny live in this house. The person who made the report is this nanny named Wu Cuimiao. She came back from the vegetable market in the afternoon and found that Xu Wanyi was People were killed in the room." Captain Xu opened his notebook, looked at it, and said.

"When did this Wu Cuimiao leave home?" Park Shangyuan asked again.

"She left home around one o'clock in the afternoon and came back at five o'clock." Captain Xu replied.

"That is to say, the deceased was killed between [-]pm and [-]pm. Okay, I have a general understanding, let's go and see the scene first." After Park Shangyuan finished speaking, he led us into the family building.

The building at the scene of the center faces north and is a six-story brick-concrete building. The crime scene is located at the east door on the fifth floor of the building.The few of us, including Qiu Xiumin, dressed neatly downstairs and walked quickly to the floor where the murder scene was located.

The door of the room at the scene faces west, and the door is a dark red iron sheet anti-theft door.I was the first to stand at the door and observe carefully. Park Shangyuan and the others took the initiative to give me a space. After 2 minutes, I took out silver powder, gold powder, and fluorescent powder from the toolbox, as well as a UV lamp.

"It seems that Dian Wei has made a lot of progress in this month, and he can distinguish the object so soon." Pu Shangyuan stood aside, squinting his eyes, watching Dian Wei's every move and said admiringly.

"Prosecutor Park, why can't I understand what you said?" Qiu Xiumin asked, pulling off the mask.

Park Shangyuan pointed to the door and explained to Qiu Xiumin: "The skin of our hands has many sweat pores that are invisible to the naked eye. These small pores will constantly secrete sweat, so as long as a person touches something, theoretically it will Fingerprints are left on it, and this kind of object with fingerprints attached is academically called an object.

"The method of collecting fingerprints is different for different objects. To give the simplest example, if you use black powder to process fingerprints left on black paper, you will definitely not see them, but you have to use white powder to process them. , then it can be clearly seen, and this is the so-called black and white. Let's take a look at the door of the crime scene."

Park Sang-won said, holding his right elbow with his left hand, looking straight ahead: "The surface of the door is a smooth paint surface, so using powder to treat it is the best choice. Although there are many things to deal with fingerprints, there are powders. , There are solutions, there are chemicals, etc., but for this impermeable object, powder is the best way, and Xiaolong chose it very accurately.

"But there are many kinds of powder materials and colors, and what kind of powder is used is also very particular. Look at this door, the door is dark red. The surface of this material is treated with silver-white silver powder, and the fingerprints are the clearest.

"Let's take a look at the handle of the door. It is made of bright silver metal. The use of gold powder in this material can have a very good contrast effect.

"Finally, let's take a look at the door frame. Under the pressure of opening and closing the door for a long time, the paint surface will peel off, resulting in different colors on the surface of the door frame. Look at this door frame, there are peeling paint flakes everywhere , so you can’t use a single color powder to deal with, and use phosphor to avoid this deficiency skillfully, because phosphor will emit weak fluorescence under the irradiation of ultraviolet light, so fingerprints will be clearly displayed .”

"There's so much knowledge here!" Qiu Xiumin's eyes on Park Shangyuan changed a lot.

"Boss, take a picture and fix it." As soon as Dian Wei finished speaking, the entire door of the room had been dealt with by him.

Dian Wei had already set up a tripod in front of the room, waiting for Pu Shangyuan to give orders.

Click, click, accompanied by the sound of the shutter of the camera, I took out the footprint survey light from another toolbox, and prepared for the next step of extracting the shoe prints on the ground.

Five minutes later, Dian Wei made an OK gesture to Park Shangyuan, and Park Shangyuan picked up the footprint inspection light and walked into the crime scene.

The whole house has a structure of three rooms and two halls.As soon as you enter the door, you will find the living room. In the living room, there is a set of sofas and a coffee table. Just to the east of the coffee table is a TV cabinet with an LCD TV.The vases on both sides of the TV cabinet were smashed to the ground, and the items on the coffee table were also messed up. A female corpse wearing a white shirt and black pants was lying on the sofa.

On the north side of the living room is the dining room, and there are uneaten leftovers on the dining table.To the north of the restaurant is the kitchen.

After the dining room and the living room are finished, there is an east-west corridor leading to the bedroom further east. To the north of the corridor are two bedrooms side by side. All the cabinet doors in the bedroom are open, apparently being tampered with.On the south side of the corridor is a bathroom and a utility room.The utility room also showed signs of being turned over.

Half an hour later, Pu Shangyuan pulled off his mask, wiped the sweat from his forehead, and shouted at the door: "Su Shuzhen, you can come in!"

Park Shangyuan picked up his toolbox and walked into the living room, walking towards the corpse.The corpse's feet were facing north, her head was facing south, and her hands were clutching the sofa cushions. She must have been in great pain before she died.

He briefly glanced at the surface features of the corpse, and then focused on the neck of the corpse.

"The deceased was strangled to death!" Park Shangyuan said with his head bowed.

"How did you tell?" Qiu Xiumin asked, frowning and glancing at the hideous corpse.

"The entire corpse has no obvious trauma or bleeding wounds. This is one. Second, the face of the deceased is purple-blue, and the mouth and nose are the most obvious parts used for breathing." Park Shangyuan opened the dead body again. The eyelids continued, "The deceased's eyeballs protruded and bloodshot eyes appeared on the eyelids. These are all manifestations of suffocation. Coupled with the irregular bruises on the deceased's neck, it can be basically concluded that she was strangled to death."

Upon hearing that the deceased was strangled to death, Su Shuzhen quickly took out the nail clippers from the toolbox, and was nervously doing disinfection work on the side.

Qiu Xiumin looked at Su Shuzhen curiously, and asked again: "Teacher Su Shuzhen, what are you doing?"

"He's preparing to extract the dead man's nails." It wasn't Su Shuzhen who spoke, but me standing aside.

"Why are you lifting your nails?" Qiu Xiumin asked the question as if breaking the casserole.

"Although it is September, the temperature is still relatively high, and people wear fewer clothes. The deceased was strangled to death, so he must have resisted before he was alive. As long as he resisted, he must have instinctive reactions such as grasping and holding. It is possible to leave the suspect's human tissue cells in the crevices of the nails of the deceased, and if there are cells, the suspect's DNA can be found through inspection, so that the suspect can basically be locked." Compared with Qiu Xiumin, who returned the food to me, I said seriously explained.

"Oh, so it is!" Qiu Xiumin nodded thoughtfully.

"Dian Wei, let's take off the dead man's clothes and have a look at the corpse watch!" Pu Shangyuan pulled the rubber gloves and turned to me and said.

"Okay!" I put on the mask again and walked to the corpse.

The deceased's top was a white shirt and a black bra from outside to inside.From outside to inside, the lower body of the deceased was a pair of black slim trousers and a pair of pink triangle underwear.
