365 Kinds of Difficult Living Methods

Imitation killing is very rare, and the motive is generally to pay tribute or show love to the murderer, and some are to try to divert the direction of police investigation. This is why the police sometimes block the news. If all the details of the case are revealed, the social impact is bad. In a serial murder case, if there is an imitation, it will be difficult to distinguish.

In the two assaults and wounding cases, there are two outstanding features: knives are inserted in the chest and abdomen, and the chest is carved with acacia flowers.

These two points are already well known. Now in the streets and alleys, whenever you talk about "Sophora japonica", the topic of "killer" will inevitably come up. Chu Yu once thought narrowly that Xia Yihan can now charge the sophora japonica for words. This night In time, it was a national hit.

When Feng Ju heard that there was a play, he felt like he asked: "How did you confirm it?"

"Because the crime process was a bit artificial," Chu Yu cleared his throat, manipulated the projector, and showed what he saw in the autopsy. "During the autopsy, we found that the deceased's body and head had scars, indicating that the deceased and the murderer had a fight. The abdomen wound was shallow and the deceased’s palm had a knife wound, indicating that the murderer first attacked the deceased’s abdomen with a knife.

But it was noticed by the deceased, holding the blade, which played a buffering effect, so the abdominal wound was not fatal. After the injury, the deceased could still fight. He probably smashed the murderer away with his head. This could explain why the capillaries under the skin of the deceased’s forehead Rupture bleeding. "

"After knocking off the killer, he grabbed the killer's head and slammed it into the trunk next to him. He tried to knock the killer unconscious, but was unsuccessful. The killer fell to the ground. The deceased wanted to struggle, and the killer put his knees against it. The deceased’s chest and hands were too strong, strangling the deceased 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 compressed. Looking at the shape of the pale area, it should be the knee. The murderer controlled the deceased with his knees, and then freed his hands to cover his mouth. Nose, squeeze the neck."

In the light of the slideshow, Chu Yu's cheeks flushed and her eyes gleamed. Although she coughed a little, she did not affect her performance at all. She seemed to be a visiting professor, talking freely 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 beside him and inserted it into his chest. At this moment, the murderer used a brutal force, causing the lungs and aortic arch to rupture. At this moment, the blood has not yet deposited. Flowing out of the body, there is the illusion of being injured by a knife, losing too much blood and dying."

The other detectives understood as soon as they heard, "So the cause of death was strangulation, and the final stab wound on the chest was intended to be covered, in order to coincide with the attack of the Phantom of the Sophora Flower!"

"Yes," Chu Yu nodded, "It is also from this detail that it can be judged that it is an imitation crime, because if the murderer's intention is to kill, he will not insert a sharp knife to carve the locust flower after strangling the dead."

Feng Ju heard this and his face changed again, "Then why can it be judged that the case is a mock murder? What if the murderer wanted to kill the dead, afraid of being arrested, and deliberately set the blame on the Phantom of Sophora japonica?"

"Because of the fighting scars on the deceased, especially the head scars, it can be inferred that the first murderer did not draw his sword. He wanted to subdue the deceased. The deceased was 176 centimeters tall and weighed 58 kilograms. 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 stun him, but was unsuccessful. Judging from the traces of the on-site fighting, the murderer and the deceased may be Regardless of top and bottom, the murderer drew the knife in desperation.

From the point of view of trying to subdue the dead, it is also imitating the Phantom of Sophora japonica, because in the two assault and wounding cases, the victims were all subdued, then sharp instruments were inserted to carve the sophora japonica flowers, and the murderer strangled the deceased to death. It should be Missed, but it is difficult to say whether the murderer really wanted to put the deceased to death. "

The voice fell, and the conference room fell silent.

"But these clues are enough," the detachment leader's voice rose uncontrollably. "If it is confirmed that the murder is imitated, then part of the murderer's personality and behavior characteristics can be confirmed, and the scope of investigation can be narrowed."

After speaking, he looked at Chu Yu, "Also ask the forensic doctor of 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. Tomorrow it is Chu forensic doctor. She would like to see, how many professions does she have to play?

Finally, after everyone discussed, the description of the suspect is as follows:

1. The internal staff of the school knew the deceased, communicated with the deceased on the day of the crime or a few days before, and arranged the deceased in the woods by speaking;

2. Indulge in perversion or crime, like to watch similar audio-visual products, there is likely to be a large collection in the residential area, such as pictures of corpses or drawings of locust flowers;

3. Young and middle-aged men, about 180 to 190 cm taller than the deceased, are suspected of having anti-social personality characteristics, strange and irritable, and are likely to have abused or killed animals or experimented with animals.

After confirming these characteristics, the task force immediately notified the principal and held a school-wide meeting, calling on teachers and students to report and expose them, asking everyone to provide clues whether they found suspicious persons and abnormal things in the school.

The school announced three reporting routes: dial the police hotline, report to the school’s security office, and set up an e-mail box so that anyone can send e-mail anonymously to make a report.

According to the content of the email, the school quickly targeted a junior named Yang Lei. The anonymous email stated that Yang Lei often bought hamsters and white rabbits back to the dormitory. Broken heart;

He has an uncomfortable personality, barely communicates with his roommates, and rarely leaves the dormitory. He stays in the dormitory every day and does not know what e-books and movies to watch.

The night when the Phantom of the Sophora Flower was exposed, the light on his bed had been on and he didn't know what he was doing. Because it was going to bed and leaving the table, the next day, my roommate found on the table the sketch paper that had fallen from his bed, with blossoming locust blossoms painted on it.

The policewoman in charge of checking the email smiled: "This anonymous email is so cute and will never tell us that he is the suspect's roommate."

After verification, the content of the e-mail is true. Yang Lei and the deceased Huang Kaiyang joined the same film club and watched a movie every Friday afternoon. However, Yang Lei had only been there twice when he joined, and later gave the president an opinion and wanted to watch it. The **** theme of murder, the opinion was not accepted, so he did not go, but this Friday, he showed up again and sat with Huang Kaiyang.

The director of the film agency responded to the police that Huang Kaiyang should like boys. He seems to have a crush on Yang Lei. He once asked him for the contact information of Yang Lei. In the middle of many times, Yang Lei did not come to watch the movie. Huang Kaiyang kept looking for him without paying attention. In the movie.

Upon hearing this, the investigator couldn't help sighing, "Huang Kaiyang must be very energetic at the invitation of his sweetheart, but he didn't expect to wait until it was a **** 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 headphones, and staring at the bright young boy inside.

"Does Lady Huaihua know that I made it? Does she know my name? Did she say that my patterns are beautifully carved? Is she happy? Does she praise me?"

Yang Lei has a handsome face, his whole person looks dignified, but his eyes are filled with excitement, and he is close to madness. It seems that he will stand on the table in the next second and sing the song "Huaihua" , Sophora japonica, I love you!"

Because of a cold, Chu Yu felt that something was blocked in her ears and her headache was splitting. She couldn't stand the sharp voice of Yang Lei, as if there was a paw scratching on the eardrum.

Taking off the earphones, she smiled coldly at the single-sided mirror: Heh, Miss Huahua's attention is not on you.

Checking the time, it was almost 24 hours since she left Luoyu City at 6 o'clock in the afternoon. Because she assisted the police in handling the case, she didn't have time to read the news, and she didn't know what was going on with Li Shan.

Walking out of the Public Security Bureau, Chu Yu was about to call Fang Datuo, and he called.

"Chu!"

This voice made Chu Yu's eardrum shook again, and his cranial nerves were almost torn apart.

"Say what happened!"

"There is good news and bad news..."

"Say together!"

"The good news is that the destination of the target 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 couple secretly ran away, and they haven't found anyone yet..."

The nerves suddenly "slapped" with a crisp sound, and his consciousness was instantly blurred. The phone fell from the palm of his hand and fell to the ground. Chu Yu softened and fell straight down.
