Imitation killings are very rare, and the motive is usually to pay tribute to the murderer or show love, and some are to try to divert the direction of police investigation. This is also why the police sometimes block the news. If all the details of the case are revealed, the social impact will be bad. In a serial murder case, if there is an imitation, it will be difficult to distinguish.
In the two cases of assault and wounding, there were two prominent features: a knife was inserted into the chest and abdomen, and the chest was engraved with acacia flowers.
These two points have been widely known. Now in the streets, whenever one talks about "Huaihua", the topic of "killer" will inevitably lead to the topic of "killer". Chu Yu once thought narrowly, Xia Yihan can now charge Huaihua for an exchange fee, this night. In time, it became a national hit.
As soon as Feng Ju heard the drama, he felt that he asked, "How did you confirm it?"
"Because the crime process is a bit contrived," Chu Yu cleared his throat and manipulated the projector, showing the autopsy findings, "During the autopsy, we found that the body and head of the deceased had scars, indicating that the deceased and the murderer had a period of fighting, The abdominal wound was shallow, and there was a knife wound on the palm of the deceased, indicating that the murderer first attacked the abdomen of the deceased with a knife.
But when the deceased noticed it, he held the blade, which acted as a buffer, so the abdominal wound was not fatal. After the injury, the deceased could still fight. He might have knocked the murderer away with his head, which could explain why the subcutaneous capillaries on the deceased's forehead Rupture bleeding. "
"After knocking over the murderer, he grabbed the murderer's head and slammed it into the tree trunk next to him, trying to knock the murderer unconscious, but was unsuccessful. The murderer fell to the ground. The deceased wanted to struggle, but the murderer used his knee The deceased's chest and hands were too strong, and the deceased was crushed to death."
Chu Yu pointed at the pale area with an infrared laser pointer, "During the death of the deceased, the sternum must have been under pressure. Judging from the shape of the pale area, it should be the knee. The murderer used his knee to control the deceased, and then used his hands to cover his mouth. Nose and neck."
In the slideshow lights, Chu Yu's cheeks were flushed and her eyes flashed. Although she coughed a little, it didn't affect her performance in the slightest. She seemed to be a visiting professor, chatting on the podium.
"Next, the bright spot came. After the murderer found that the deceased was out of breath, he immediately picked up the sharp knife that fell next to him and inserted it into his chest. At this moment, the murderer used ruthless force, causing the lungs and aortic arch to rupture. At this moment, the blood has not yet deposited, Out of the body, there is the illusion of being wounded by a knife, bleeding too much and dying."
The other detectives understood as soon as they heard it, "So the cause of death was strangulation, and the final stab wound to the chest was to be concealed, in order to coincide with the attack of the Huaihua Phantom!"
"Yes," Chu Yu nodded, "It is also from this detail that it can be judged that it was an imitation, because if the murderer's intention was only to kill, he would not insert a sharp knife and carve a locust flower after strangling the victim."
After hearing this, Bureau Feng's face changed again, "Then why can it be judged that the case is an imitation murder? What if the murderer wanted to kill the deceased and was afraid of being arrested, so he deliberately blamed the Phantom of Huaihua?"
"Because of the combat scars on the deceased's body, especially the scars on the head, it can be inferred that the first murderer did not draw a knife. He wanted to subdue the deceased. The deceased was 176 cm tall and weighed 58 kg. Maybe the murderer underestimated his strength and wanted to subdue him. The brain tissue of the deceased was damaged, but it was not fatal. The murderer probably wanted to knock him unconscious, but was unsuccessful. From the traces of the fight on the spot, it seems that the murderer and the deceased may have Regardless of whether it was up or down, the murderer pulled the knife out of desperation.
From the point of view of wanting to subdue the deceased, it is also imitating the phantom of the locust flower, because in the two assaults and wounding cases, the victims were subdued, and then they were inserted into sharp objects to carve the locust flower, and finally the murderer strangled the deceased to death, it should be It was a miss, but it was hard to say whether the murderer really wanted to kill the deceased. "
The voice fell, and the meeting room fell into silence.
"But these clues are enough," the detachment leader's voice rose uncontrollably. "If it is confirmed that it is a case of imitation murder, then part of the character and behavior characteristics of the murderer can be confirmed and the scope of the investigation can be narrowed."
After he finished speaking, he looked at Chu Yu, "Please also ask forensic doctor Chu to help analyze and correct it based on the autopsy results."
Chu Yu: "..."
Yesterday it was Police Officer Chu, today it is Doctor Chu, and tomorrow it is Forensic Doctor Chu. She would like to see how many occupations she has to play
Finally, after everyone's discussion, the characterization of the criminal suspect is as follows:
1. The internal staff of the school, who knew the deceased, communicated with the deceased on the day of the crime or a few days ago, and asked the deceased to go to the woods through oral speech;
2. Indulge in perversion or crime, like to watch similar audio-visual products, and there may be a large number of collections in the residence, such as pictures of corpses or drawings of locust flowers;
3. Young and middle-aged male, taller than the deceased, about 180 to 190 centimeters, suspected to have anti-social personality characteristics, eccentric personality, irritable, and likely to have tortured animals or used animals for experiments.
After confirming these characteristics, the task force immediately notified the principal, held a school-wide meeting, called on teachers and students to report and expose, and asked everyone to provide clues as to whether suspicious persons and unusual things were found in the school.
The school has announced three reporting methods: calling the police hotline, reporting to the school’s security department, and setting up an e-mail box where anyone can send an anonymous e-mail to report.
According to the content of the email, the school quickly targeted a third-year student named Yang Lei. The anonymous email stated that Yang Lei often bought hamsters and white rabbits to return to the dormitory, but he did not raise them. broken heart;
He is not gregarious, has little communication with roommates, and rarely leaves the dormitory. He stays in the dormitory every day and doesn't know what e-books and movies to watch.
On the night when the Phantom of Sophora japonica was exposed, the light on his bed was always on, and he didn't know what he was doing. Because it was going to bed and getting off the table, the next day, the roommate found on the table a sketch paper that had fallen from his bed, with blooming acacia flowers drawn on it.
The policewoman in charge of checking the email smiled: "This anonymous email is so cute, it will never tell us that he is the suspect's roommate."
After verification, the content of the email was true. Yang Lei and the deceased Huang Kaiyang joined the same film club and would enjoy a movie every Friday afternoon, but Yang Lei had only been there twice when he joined. Murder and bloody themes, the opinion was not adopted, he did not go, but this Friday, he showed up again and sat down with Huang Kaiyang.
The director of the film club responded to the police that Huang Kaiyang should like boys. He seemed to have a crush on Yang Lei and asked him for Yang Lei’s contact information. Many times Yang Lei didn’t come to watch the movie. Huang Kaiyang kept looking for him, but he didn’t pay attention. on film.
Hearing this, the investigator couldn't help but sigh, "Huang Kaiyang must have been very happy at the invitation of his sweetheart, but he didn't expect it to be a bloody knife."
The criminal police team immediately arrested Yang Lei and compared his DNA with the blood DNA left by the murderer at the crime scene. The test results came out quickly and were completely consistent.
Chu Yu stood outside the interrogation room, wearing earphones, staring at the bright young man inside.
"Does Huaihua know that I made it? Does she know my name? Did she say that my pattern was beautifully carved? Is she happy? Did she praise me?"
Yang Lei has a handsome and compelling face, and the whole person looks dignified, but there is excitement in those eyes, which is close to madness. , Huaihua, I love you!"
Because of the cold, Chu Yu felt that something was blocked in her ears, and she had a splitting headache. She couldn't stand Yang Lei's high-pitched voice, as if a claw was scratching on the eardrum.
Taking off her earphones, she smiled coldly at the one-way mirror: Oh, girl Sophora japonica isn't paying attention to you.
Looking at the time, it was almost 24 hours since she left Luoyu City at six o'clock in the afternoon. Because she was assisting the police in handling the case, she didn't have time to read the news, and she didn't know what happened to Li Shan.
Walking out of the Public Security Bureau, Chu Yu was about to call Fang Datuo when he called.
"Chu!"
This roar made Chu Yu's eardrums tremble again, and his cranial nerves were about to burst.
"Say what!"
"There is good news and bad news..."
"Speak together!"
"The good news is that the target's foothold has been found!"
Chu Yu's eyes lit up, and he couldn't help speeding up, walking towards the wooden fish waiting outside.
"The bad news is that the He and his wife sneaked away, and no one has been found yet..."
There was a sudden "snap" in the nerves, and his consciousness was instantly blurred. The phone fell from the palm of his hand and fell to the ground. Chu Yu's body softened and he fell straight down.
