Reborn in 1995, Criminal Investigation Records

Liu Chengyu is communicating with the head of the local police station about the situation at the scene; this step is crucial.

In cases of unnatural death, the police officers from the local police station are usually the first to arrive at the scene.

After the other party arrives at the scene, the first thing to do is to protect the integrity of the scene, then control all people present, and finally, based on the report from the scene, conduct preliminary questioning of the person who reported the case and the surrounding crowd.

These were crucial for the subsequent investigation by criminal investigators.

"What's wrong?" Liu Chengyu, who was in the middle of the conversation, turned his head, his eyes revealing a question.

He was generally satisfied with Zhou Yang's performance today. It was rare that he didn't turn pale or vomit after seeing the body on his first visit to the scene.

If someone can also proactively make judgments and analyses based on the situation at the scene, then they are simply born to be a criminal investigator.

Zhou Yang pondered for a moment, his eyes darting around, actually thinking about how to answer: He couldn't very well say that he was only stabbed in his past life, and that he actually died in this life.

"The location is wrong!" Zhou Yang pointed to the peeling paint on the abandoned street lamp frame above his head: "Master, look, this is clearly an old, discarded street lamp!"

He then pointed to the other side of the road: "There are streetlights in use less than 50 meters away. There's no reason for the deceased to walk this way."

"Maybe he wanted to save time and walk fewer steps!" the director casually remarked while talking to Liu Chengyu. "It's a pity he lost his life trying to save effort!"

"Possibly, but it doesn't make sense!" Zhou Yang shook his head. "The deceased lived in Fengdu Garden. No matter which gate she entered or exited, she shouldn't have walked this way. She wouldn't have walked on a smooth road under a good light, but instead went around to the dark garbage dump on the south side. That doesn't make sense! Besides, the deceased's clothing indicates that she was someone who cared about her appearance!"

As he spoke, he pointed to the pile of garbage at his feet. The weather in July was already a bit muggy, and the fermenting, sour smell from the garbage pile was really refreshing.

Liu Chengyu glanced at Zhou Yang in surprise. He had just taken a quick look at the deceased, and his attire was indeed sophisticated, or as we would say now, fashionable. He hadn't expected that the other party had also noticed it.

I never realized this kid had such strong observation and logic skills. Did he only suddenly become so insightful when faced with a murder case?

"They're probably here to throw out the trash!" the station chief muttered.

"Putting aside the fact that it's late at night to throw out the trash, you said it yourself that you were throwing it out, not leaving it there. There's no need to walk so close. The trash is less than a meter away from the curb!" Zhou Yang explained.

"Zhou Yang, how did you know the deceased lived in this neighborhood?" Wang Chao, who had just finished his work, asked casually as he walked over.

Oops!

Zhou Yang's heart tightened. He definitely knew, but that was in his past life.

The deceased was lying on the ground, his face obscured, so his features were not visible. However, his build and the location of the stabbing were the same as in his previous life. He subconsciously assumed it was that case, but accidentally let it slip.

"Isn't that right?" Zhou Yang feigned an embarrassed expression. "I thought it was someone from this neighborhood!"

"It's alright. Make bold assumptions, verify them carefully. After the Fourth Brigade arrives, we'll conduct further interviews to understand the relationship with the deceased!" Liu Chengyu nodded, encouraging Zhou Yang, and couldn't help but feel more satisfied with his apprentice.

In fact, the police station's initial questioning has basically confirmed that the deceased was a resident of the community, but further confirmation is still needed.

Zhou Yang nodded, stepped aside, and the information in the file in his mind gradually became clearer:

Deng Fangfang, female, 46 years old, residing at Unit 401, 4th Floor, Building 3, Fengdu Garden Community.

In the original case, she was attacked on her way home at night and stabbed, but not fatally. The next day, she identified her husband, Zhu Guolong, as the perpetrator. However, when the police arrived at her home, they found that Zhu Guolong had committed suicide out of fear of punishment and left a suicide note. The note confessed to the fact that he had stabbed his wife.

But at this moment, lying on the ground was a corpse that showed no signs of life.

Something must have gone wrong! Zhou Yang frowned as he surveyed the surroundings along the corpse.

In other words, even in the future, criminal investigators cannot get too close to the scene before the technicians have finished examining it, so as not to contaminate the scene.

As he approached, he saw that the bloodstains were divided into two pools, one on the head and the other on the chest and abdomen. The back of the head was noticeably dented, and the hair was soaked in dark bloodstains.

Soon after, two police cars arrived at the scene one after another, carrying colleagues from the First Brigade who had received the news. Across lifetimes, seeing the familiar young faces on this piece of paper, Zhou Yang naturally felt a pang of emotion.

They got out of the car, nodded to Zhou Yang, and quickly began their on-site investigation and interviews. Everything was proceeding in an orderly manner.

Zhou Yang was a newcomer, and it was his first time at a murder scene. Liu Chengyu didn't give him any specific tasks, only instructing him to observe and think as much as possible without disturbing others.

The technical team from the Fourth Brigade also arrived, led by Wang Zhenhai, a forensic doctor.

Many people have a misconception that forensic medicine, exploration, imaging, trace evidence, and laboratory testing are separate groups, but that's not the case. They all belong to the technical team.

Upon arriving at the scene, they first changed into some protective gear, and then, without touching the body, observed the deceased's original position and posture.

Next comes the inspection of the clothing's integrity, followed by a physical examination, evidence collection, and finally, a preliminary assessment.

The exploration team, trace evidence team, and imaging team each performed their respective duties, collecting traces, physical evidence, and taking photos at the scene.

More than half an hour later, the body was loaded onto the vehicle, and the next step was to take it to the funeral home.

Funeral homes don't just cremate corpses; they have dedicated forensic centers with complete equipment, including tools for autopsies and refrigerated cabinets.

The next step is to wait for the family to claim the items.

"Liu Da!" Wang Zhenhai took off his gloves and mask and called out to Liu Chengyu, who was waiting beside him.

「根据尸体肛温温度，结合尸僵形成程度及尸斑按压褪色情况，初步判断死亡时间间隔约为6-8小时，死亡时间大概在昨夜23:30至今日01:30之间。

Of course, this is a general range. If you want to be more precise, you need to perform a systematic dissection and then determine the range based on parameters such as liver temperature and gastrointestinal emptying.

The body showed two main injuries, one of which was on the abdomen. The bloodstains were not obvious, the wound edges were neat, and the corners of the wound were one blunt and one sharp, consistent with being stabbed by a single-edged sharp weapon.

Secondly, located on the occipital region, there was an irregular scalp laceration with interstitial bridging around the wound. Microparticle evidence extracted from the wound cavity needs to be sent for testing, but the preliminary judgment is that it was formed by repeated blows from a blunt object such as brick or stone.

The current assessment is that the skull fracture accompanied by intracranial hemorrhage is considered a fatal traumatic brain injury.

Based on the analysis of the distribution and dripping pattern of bloodstains at the scene, the victim was initially attacked at this location, and subsequently suffered continuous blunt force trauma while moving to this location.

The footprints at the scene were scattered and overlapping. Three-dimensional footprint molds have been made, but no suspected shoe prints with clear identification value have been selected yet.

Further examination of other injury characteristics and biological samples will be conducted after systematic anatomical dissection and laboratory analysis.

"Thank you for your hard work!" Liu Chengyu nodded. "Xiao Zhou, please see Forensic Doctor Wang off for me!"

"Yes, Master!" Zhou Yang reached out and picked up Wang Zhenhai's suitcase. "Teacher Wang, what you just said means that the deceased was first stabbed with a dagger and then hit on the back of the head. Can you determine whether it was the left or right hand?"

The forensic doctor, Wang, was pinching his brow when he heard this. He paused, then walked to the car, put on his gloves, fiddled with them for a moment, and his smile broadened slightly. "Liu Da has taken on a good apprentice. He uses his right hand to hold sharp objects and his left hand to use blunt objects. Of course, this is just my personal experience; I will indicate this in the subsequent report!"

"His words are so impeccable," Zhou Yang sighed, watching the other person leave before turning around and jogging back to the scene.

"Master, there's a high probability that there are two murderers!" Zhou Yang approached Liu Chengyu and quietly told him about the forensic doctor Wang's assessment.

"Two?" Liu Chengyu took a cigarette out of the crumpled cigarette box and put it in his mouth. Zhou Yang touched his pocket and then remembered that he no longer smoked.

Liu Chengyu didn't see his movements. He simply reached into his pocket and pulled out a bright yellow plastic lighter with the "Good Luck Restaurant" brand printed on it.

"Click—" The pulley rubbed against the flint, but it didn't ignite.

Then he turned up the collar of his jacket, hunched his neck, cupped his hands into a half-bowl shape, skillfully blocked the wind, and lowered his head slightly to bring the cigarette butt closer.

He blocked out the wind, and also blocked Zhou Yang's gaze: "Come with me to see the person who filed the report!"
