The Rise of the Peninsula

214 0177 – Interrogation
"It smells so bad! Why are her panties wet?" Qiu Xiumin frowned when Dian Wei pulled off the deceased's trousers.

Park Shangyuan seemed to be extremely patient with Qiu Xiumin, and explained to her:

"Muscles will relax first after death, especially those with underdeveloped muscles. Women generally lack muscles, and the corpse spots on the back of women's corpses can also be analyzed. Look at the hands of the deceased. It is completely unreasonable to hold on to the sofa cushion tightly. As Xiaolong said, if a person is choked by someone, the first reaction should be to grasp, grasp and other instinctive reactions of struggle. How could it be possible to grab the sofa cushion with hands? This is also deliberately disguised by the suspect, in order to make us believe that the deceased was killed on the sofa, so as to cover up the relationship between him and the deceased!"

"Besides herself, there were only two people living in the deceased's house. One was the nanny, and the other was the deceased's husband. Could it be that the suspect was one of them?" I widened my eyes and expressed my conjecture.

"This possibility is not ruled out. Let's wait until the on-site processing is completed, and all the physical evidence is combined together, and then we will do a systematic analysis!" Park Shangyuan said to us.

Two hours later, the physical evidence was brought back to the technical room, and the body was sent to the funeral home's autopsy room.As soon as we arrived at the unit, we worked separately.Pu Shangyuan and Dianwei were responsible for the dissection, Su Shuzhen opened the door of the physical and chemical laboratory with the test materials, and I was in the trace laboratory, preparing to conduct detailed analysis of the footprints and fingerprints extracted on the spot.

Qiu Xiumin and colleagues from the criminal police team are responsible for guarding the two most important people involved in this case - the nanny Wu Cuimiao and the deceased's husband Liu Jianliang.

The processing of physical evidence can be described as intense and exciting, because any detail can lead to a huge change in the direction of investigation.

Take Park Sang-won as an example, he can infer from a pair of trousers that an acquaintance committed the crime. If he fails to notice this detail, it may lead to a deviation in the direction of the investigation, not to mention delaying the time to solve the case, and may even cause the case to fail to be solved. Dilemma.This is the first time I have dealt with traces alone in the laboratory after studying, so I am extra careful and cautious.

Four hours later, several of us sat in the conference room to discuss the handling of traces and physical evidence. Of course, Qiu Xiumin must be indispensable here, while the investigators of the criminal police team were waiting outside in an orderly manner.

This is the rule set by Park Sang-won himself.

Because the main job of our technical room is to deal with the physical evidence at the scene of the crime. Only when all the physical evidence is strung together into a chain of evidence can we guide and solve the case, so the meetings between technical personnel are very professional. If there are more people involved, It is inevitable that there will be non-stop questioning, so in order to save time in handling the case as much as possible, Park Shangyuan stipulated that other investigators of the criminal police team are not allowed to participate in this kind of meeting. After we discuss the results, they can investigate according to the clues.

At this time, Pu Shangyuan was sitting on the front seat of the meeting room, Dian Wei was sitting on Pu Shangyuan's left hand side, Qiu Xiumin and Su Shuzhen were sitting on Pu Shangyuan's right hand side.

After looking around for a week, Pu Shangyuan opened his notebook, and his eyes fell on me: "This case, Su Shuzhen will talk about it first."

Hearing his name, Su Shuzhen was a little surprised, because according to the previous procedures, it was Park Shangyuan who spoke first, but this time it was me who spoke first.I was flattered to glance at Park Shangyuan, opened Su Shuzhen's black notebook, stared at the black pen writing, cleared my throat and said: "I extracted two types of traces at the scene, the first type: fingerprints; the second type: footprint.

"Let me start with the fingerprints. I extracted a total of three fingerprints on the door of the room at the scene, the surface of the furniture that was turned upside down, and objects that the suspect may have touched. After comparison, one was the deceased himself. One was Wu Cuimiao, the nanny, and the other was Liu Jianliang, the husband of the deceased. Apart from these three fingerprints, there was no fourth fingerprint at the scene. From this, I can judge that the suspect either wore gloves, or the nanny and the husband of the deceased One of the two."

After finishing speaking, Su Shuzhen took a sip of water from his teacup and continued: "After talking about fingerprints, I will continue to talk about footprints. The whole scene is very strange. There is only one kind of shoe print, which is the slipper print of the deceased's home. I observed at the scene and found that the deceased The slippers used at home belong to the one-size-fits-all type of sandals and slippers, so the size and style of the shoes are the same. Through this, it is not difficult to see that the suspect changed into slippers when he entered the room to commit the crime.

"We assumed two situations at the scene where the suspect entered the room. Because there were no signs of prying on the door at the scene of the crime, the reporter Wu Cuimiao was also sure that she locked the door from the outside when she left home. So the suspect either had the key to open the door, or the dead man opened the door for him.

"Let's talk about the first way to open the door—opening the door with a key. Let's not care where the suspect got the key. After opening the door, he will subconsciously take off his shoes to change into slippers. This shows that he is very serious about this case. The scene is quite familiar, and it’s definitely not the first time he’s been here. His subconscious behavior of changing slippers has formed a mindset. As soon as he comes into contact with this environment, he thinks about changing shoes. For example, if I When I return to my home, the first thing I do is to find my own slippers, but if I go to a strange environment, I may not have such a subconscious action. The first situation shows that the suspect is very familiar with the place where the deceased lived. Familiar with.

"Another situation is that the deceased opened the door for the suspect. We have also seen that the pajamas worn by the deceased are so thin that the underwear inside can be vaguely seen from the outside. If the deceased is not familiar with the suspect, open the door. I would never dress so casually."

Park Sang-won nodded at me while listening.

Su Shuzhen took out a pack of cigarettes from his pocket and handed them out. After lighting it, he continued: "In addition, I noticed a detail. Have you noticed that the deceased was lying on the sofa without shoes?" Everyone frowned and recalled carefully.

"Yes, I didn't wear shoes." Dian Wei took out his camera and found the photos of the dead bodies at the scene.

"Boss, look for the photo of the bedroom where the pajamas were found." I tilted my head and glanced at the camera.

Dian Wei nodded, and quickly pressed the button on the camera.Su Shuzhen squinted his eyes and observed: "Stop, this is the one."

"Enlarge the part on the ground next to the bed." Park Shangyuan said from the side.

"Slippers? There are slippers by the bed!" Dian Wei said as he handed the camera to Park Shangyuan, who then passed it to Su Shuzhen and Qiu Xiumin after watching it.

Park Shangyuan looked at the camera and returned it to Dian Wei's hand again, and continued: "The suspect was so busy carrying the corpse out of the bedroom, but forgot the deceased's shoes on the ground. This is enough to prove that the deceased was killed in the bedroom." The deceased was wearing pajamas in the bedroom, and should have been sleeping on the bed. So my conclusion is basically similar to Park Sang-won's: the relationship between the suspect and the deceased was not an ordinary friend relationship, but a very familiar relationship, and the messed up cabinets at the crime scene were also Well, the broken vase is fine, it’s just a means for the suspect to fake the scene. That’s all I want to say.”

Park Shangyuan didn't speak after listening, but stared at me blankly for 1 minute. I read the surprise from his eyes. Obviously, my analysis has exceeded his expectations.When the cigarette in his hand almost burned his fingers, he came back to his senses.

Pu Shangyuan pinched the cigarette butt in his hand into the ashtray, stared at me with straight eyes, raised the corner of his mouth and slapped my palm hard three times.

"Amazing! Since when did you become so smart!" Dian Wei slapped Su Shuzhen on the shoulder and said with a smile.

Su Shuzhen pushed his glasses and gave Pu Shangyuan a thumbs up.Qiu Xiumin looked at me with incredible eyes, she must be wondering in her heart, I was a rookie a month ago, how can I become so powerful now?

After working in the department for one year, three months and fifteen days, I enjoyed the joy of being recognized for the first time. To be honest, this feeling is really good!
Pu Shangyuan took out a pack of unopened soft China from his jacket pocket, quickly opened it, and threw the first cigarette to me, then he lit it comfortably with a smile on his lips, took a puff and said: "Xiaolong said It's over, let me tell you."

I corrected my sitting posture, picked up the pen and prepared to record.

Seeing that everyone was ready, he said, "After the autopsy, it was found that the deceased died of mechanical suffocation. In addition to the on-site analysis, it can basically be determined that he was strangled to death. After Guoxian's test on the contents of the deceased's stomach Analysis found that there was no poison in the stomach of the deceased.

"She had just had lunch before she died. Based on the analysis of the remaining amount of food in her stomach and the spots on the corpse, the specific time of death should be around 1:30 p.m. Xian, tell me about your inspection situation."

Su Shuzhen took out a DNA report and put it on the conference table, pushed his glasses and said, "There was no human biological tissue found in the nails of the deceased. Come and analyze it, why did this happen?"

With Su Shuzhen's question, the few of us fell into thinking again, and after dozens of seconds, Park Shangyuan said: "Even if the deceased was strangled to death in his sleep, it is impossible not to resist, because it is an instinct. No human tissue was found in the dead man's nails, which shows that the dead man did not come into contact with the suspect's skin.

"It's hot weather now. If the suspect was wearing a T-shirt, it is impossible for the deceased to touch the suspect's skin. So from this point of view, I can analyze that the suspect is likely to be wearing a long-sleeved shirt. I guess he is wearing a T-shirt. Gloves."

"On such a hot day, there must not be many people wearing long-sleeved shirts. We just need to see if there is any monitoring equipment around the crime scene, and find out all the people who wore long-sleeved shirts during the time of the crime. The suspect must be there." Inside." Qiu Xiumin slapped the table excitedly and said.

"I'm afraid I'm going to disappoint you." Dian Wei put the camera aside and said with a sad face.

Dian Wei has always been responsible for the monitoring and retrieval of the murder scene. When he said this, everyone basically understood that there must be no monitoring equipment around the scene.But it's no wonder that the medical community has a history of at least ten years, and it is normal for such an old community to not install monitoring equipment.

Park Shangyuan closed his notebook, took a puff of cigarette and said:

"Okay, now that the physical evidence is basically analyzed, we generally have an investigation goal, which is to start around the social relationship of the deceased. All people who are familiar with the deceased and have a better understanding of the family environment of the deceased are the focus of our investigation. Now the case The most important thing in the investigation is the two people downstairs, it can be said that they are the most suspected."

"Which one of the two should ask first?" I asked with some doubts.

"This kind of thing is clear to the bystanders. Call the nanny first." Park Shangyuan said as he pinched out the butt of his cigarette.

"I'll call someone." Qiu Xiumin volunteered to stand up.I can understand her current mood. After a meeting, she didn't intervene at all. Now that she finally has a job she can handle, of course she will be the first to stand up.

"Dianwei, you are with Qiu Xiumin." Park Shangyuan stretched his neck at me and said.

"Oh." Dian Wei nodded reluctantly.

The boss is still the same, even though he has been in Daegu for so long, he still doesn't want to believe in himself and insists on letting himself do such errands.

Logically speaking, this kind of thing should be handed over to the criminal police, but the boss can't trust them, so there is no other way but to run around by himself.

As soon as the two of them left the house, Qiu Xiumin asked curiously, "Which teacher did you study with last month? Why do you seem to be a different person when you come back?"

"I'm acting in my true colors." I patted my chest and joked with her.

Qiu Xiumin pursed her lips, rolled her eyes and looked at me without answering.

"Wu Cuimiao, come up with us." Qiu Xiumin shouted to an old woman wearing an apron standing at the stairs.

"Oh." Wu Cuimiao rubbed her hands nervously, then turned her head to look at the man in suit and leather shoes sitting beside her.

"Sister Wu, go, it's okay." The man persuaded.

"Hey." Wu Cuimiao nodded dully, got up and walked towards us.

When Wu Cuimiao approached, I saw that there was a bruise on her neck. It seemed that this woman must have been pinched severely just now.Seeing her neck, my heart became inexplicably irritable.

After Qiu Xiumin brought Wu Cuimiao into the conference room, she first asked about Wu Cuimiao's birthday and work experience, and then asked her about her usual preferences.Under our questioning, she recalled slowly, and began to describe it in detail. After listening to her for a long time, she didn't come up with any clues. In the end, Qiu Xiumin and I decided to take a risky move and use this The loopholes in the woman's words are used to detect the specific method of death of the deceased.
