ICS Homicide Tracking

The three of them just sat in the interrogation room for three hours. It seemed that the next day was coming, and Chen Yan lost her patience and got up to leave.

Li Qi immediately stopped him, turned around and asked Shi Han, "What do you want to do? It's been three hours."

Shi Han nodded, "Well, it's time."

As soon as he finished speaking, there was a knock on the door of the interrogation room, and Shi Han strolled towards the door, only to see Yuan Xin delivering the report with big dark circles under his eyes.

"Thank you."

After Shi Han thanked him, he opened the report and glanced at it to be more sure of his thoughts, then walked back to the table and sat down.

His slender fingers reached across the table and tapped lightly, "Sit down, we can start."

Chen Yan hesitated and sat back to her original position, her heart seemed not as firm as before.

"I just said that you are a very calm person, and you seem to have done this whole thing very cleanly." Shi Han said "seemingly", but it was not really clean, and then he said to There was a greeting from outside the interrogation room.

The TV in the interrogation room was immediately turned on, showing He Xia helping Chen Yan cheat, but because of He Xia's position and Chen Yan's intentional cover-up, the monitoring could only see Chen Yan answering the note, but could not capture her The process of cheating.

"I'm very surprised why He Xia tore up all the other cheat sheets, but kept these two." Shi Han said, took out the two cheat sheets that He Xia had put in the book, and continued, "The Physical Evidence Department is very experienced. , they rubbed it again with a pencil and found another person's handwriting on the note."

Shi Han took out Chen Yan's exam paper, one of the questions was at the same height as the handwriting on the note.

"Maybe He Xia imitated my handwriting and tried to pour dirty water on me?" Chen Yan still refused to admit it.

Shi Han took out the handwriting identification report, "Everyone has their own habits when writing, the gaps left between gestures are different, the strength of writing and the font style are also different, and the handwriting on this cheat sheet is the same as yours. The handwriting is highly consistent."

Seeing that Chen Yan was still trying to argue, Shi Han didn't continue to listen, but said: "The bruises on the surface of the deceased's body match the shape of your iron ruler, and there is your DNA on it, as well as He Xia's DNA. There is no need to repeat He Xia. Xia’s self-mutilation speech is over, the external force and personal injury may not be seen by others, but I am a forensic doctor.”

Most of the rectangular bruises on the corpse are obliquely downward, and the point of force is on the side of the body, so the bruises are more serious. Normal people will curl up involuntarily when they are hit by someone when they are awake and unrestrained Defense, so the inside of the corpse's arm only has the self-mutilation injuries of the deceased, and it is impossible to make such bruises by itself.

"And the wound on your arm." Shi Han took out the tetanus medicine list in the trash can, "You must have touched some rusty place, so go for a tetanus!"

Chen Yan glanced at the list and regained her composure, "So what, I accidentally scratched it."

Shi Han went up to check the wound himself, and saw that the gauze had been removed from Chen Yan's arm. The wound was not a contusion, but two scratches nearly ten centimeters long.

"Being so cruel to yourself?" Li Qi gasped. Is this Chen Yan really just a little girl?

Shi Han shook his head, "The more you do, the more mistakes you make. The wound has such a large area and there is bleeding. When you go to the hospital, the doctor doesn't suture you, but gives you a tetanus. This is unreasonable."

Chen Yan retorted: "It was something rusty that scratched me, so I went for a tetanus. I didn't ask the doctor to sew me up because I wanted to heal myself, can't I?"

Shi Han still shook his head, "Since the sharp weapon that scratched you is rusty, your wound shouldn't be so smooth."

"And..." Shi Han took out the iodine that Chen Yan put on the bedside, "You opened this bottle of iodine, but it was useless, because your wound is an open, sexual, wound, you can't apply iodine, and I turned it over Your trash can doesn’t have a cotton swab with medicine. I think you scratched yourself and wanted to disinfect after stopping the bleeding, but suddenly found that you bought the wrong one, so you stopped to stop the bleeding.”

The physical evidence department found a blood reaction on the sink in the dormitory. The DNA test results showed that the blood belonged to Chen Yan, but there were no bandages and gauze to stop the bleeding. Out of the dormitory, until the female colleague of the physical evidence department found that the sanitary napkin in the toilet garbage was not right, and the blood on it was not menstrual blood.

Although both iodophor and iodine have disinfection effect, the disinfection and corrosion ability of iodine is stronger than that of iodophor. Iodophor can disinfect wounds, but iodine must be deiodized again, otherwise it will corrode the wound.

Chen Yan wanted to scratch herself and destroy the marks of being scratched by the railing on the roof, but it was very secretive.

"Besides, we have checked, and there is no knife in your dormitory that can hurt people, so where did the wound on your hand come from?" Shi Han took out a box of eyebrow razor blades. This kind of blade is very sharp and is very common in female dormitories.The female police officer in their team found another problem immediately after discovering the blood problem in the sanitary napkin, and found the blade.

However, none of the remaining blades in the box had a blood reaction, so they should have been washed away with the blood after Chen Yan used them.

Shi Han took a pen from the table, pointed to Chen Yan's hand and said, "Your wrist has a ring-shaped bruise. When He Xia fell off the roof, it must have been here! Although you ruined the bruise on your arm , but you also have contusions on your elbows, and you could indeed say you got the bruises from a fall, but..."

As he said, he took out the report that Yuan Xin had just sent, "Just because you wiped off the blood on the surface of the railings on the roof, it doesn't mean that the blood has been completely wiped off. We can still find you."

Shi Han walked back to his seat and sat down, and said calmly, "You don't need to lie anymore. I don't think you know that the job of a forensic doctor is not only to examine the corpse, but also a very important job, which is the identification of scars."

Chen Yan desperately wanted to erase the evidence of her crime, but also left evidence of her existence, which was an equivalent exchange.

Chen Yan, who insisted that she was not the murderer just now, looked at the physical evidence on the table in front of her, and completely lost the ability to resist. She leaned on the back of the chair weakly, looked up at the ceiling, and said helplessly: "That's right. , I pushed He Xia downstairs."

"I found out that He Xia was cheating a long time ago. I threatened her with the cheat sheet that He Xia had secretly thrown away, and wanted her to help me too. But after she helped me once, she said she wouldn't help. I couldn't hold back and beat her up. In order to force her to help me honestly, I secretly took photos of her taking a bath as a threat, and the photos are all in the phone, you can take them.”

As Chen Yan said, she threw her mobile phone on the table. With such a big hat on her head, the ICS will find those photos in the mobile phone sooner or later, so she might as well recruit herself. He patted the table and vented his emotions: "Because she exposed herself, she wanted to report me and let me accompany her! Can't she sacrifice herself and protect me? What kind of friend is she!"

While talking, Chen Yan suddenly calmed down again, looked at the two people in front of her, and said quietly: "Do you know that He Xia has depression, she will harm herself, she wants to die herself, she will die sooner or later, why? Is it worthwhile not to die?"

Li Qi swears that he seldom gets angry with girls, but he really can't stand Chen Yan's attitude, so he cursed loudly: "Value? People can only create their own value when they are alive. What is your so-called value?" Trampling on the flesh and blood of others is not value, it is your selfishness and greed!"

"She doesn't want to die." Shi Han said, pointing to the ring-shaped bruise on Chen Yan's wrist again, "She has been taking medicine on time, and she also took medicine before she went out to find you. When you attacked her, she told you Rescue, you deprived her of the right to live."
