You're supposed to be a security officer, what case are you solving?

Chapter 265 Reconstructing the Crime Scene!

Zhou Changyuan's face turned ashen, and then he turned his gaze to Yang Jinwen.

"Captain Yang, do you mean this mysterious... this person hiding in the shadows, moved this clock?"

Clearly, Zhou Changyuan didn't like using the term "mysterious person."

"Most likely." Yang Jinwen turned the clock over, revealing the battery compartment on the back, and added, "The battery was also taken by this person."

"Then why did he do that?"

Yang Jinwen held the watch upright in front of everyone.

The clock, minutes, and seconds all point to 5 p.m.

Some wall clocks display a calendar, but this wall clock only displays the time.

"Five o'clock?" Zhou Changyuan frowned. "What does that mean?"

At this moment, Yao Weihua, who was sitting by the window, muttered, "When will the murderer kill again?"

"No, how did you come to this conclusion?" Fu Mingyuan asked. Danan County often has some major criminal cases, but a serial murder case is indeed infuriating.

Yao Weihua shrugged: "That's how it's portrayed on TV. The murderer leaves marks or symbols with special meaning at the scene. Sometimes it's to show off, and sometimes it's to give clues to the law enforcement agencies."

"So, you're saying this is a serial murder case?"

The rain outside the window pattered against the glass.

Yao Weihua felt a chill, shrank his neck, and replied, "Anyway, judging from the body and the scene, this is definitely not the first time the murderer has killed someone."

Zhou Changyuan looked at Yang Jinwen: "Captain Yang, what do you think?"

“I agree with Lao Yao’s judgment; this is not the first time the murderer has committed a crime.”

"Let's talk about it in detail."

Yang Jinwen stood up and moved a whiteboard from the corner of the wall.

He took a watercolor pen and drew a simple floor plan of the crime scene on the whiteboard.

"The incident occurred on May 28th. According to the forensic examination, the victim was killed between 7:30 PM and 9:00 PM, which is an hour and a half."

If Yang Jianhui wasn't lying and he didn't kill the person, then the timeframe is shortened to between 7:30 and 8:30.

We assume that the victim, Yu Jing, was murdered during this one-hour period.

Everyone knows what Yu Jing's profession is, and she was working that night.

Since the door was not damaged, it can be concluded that the murderer either opened the door himself or she helped him open it.

The room where the crime occurred was empty of the tenants on either side, and the other residents didn't hear any noise either. This indirectly suggests that Yu Jing and the murderer knew each other, which is highly likely.

Yu Jing's clothes were stripped off and thrown on the bed, and the clothes were intact without any signs of tearing.

Therefore, it is highly likely that she took off her clothes herself.

Moreover, there was two hundred yuan in cash stuffed under the pillow on the bed.

Where did this money come from? Everyone should know the answer; it's the payment from the person who came in…

Yang Jinwen paused, and Yao Weihua seized the opportunity to interject: "Captain Yang's analysis is very reasonable. With the money in place, taking off one's clothes is a logical step."

Hearing this, Cai Ting rolled her eyes at him.

Zhou Changyuan looked at the several forensic examiners whose heads were locked and asked, "There will definitely be fingerprints on the money, not only from the victims but also from the people who gave the money to the victims. Have you checked that?"

Fu Mingyuan quickly explained, "Director Zhou, Yang Jianhui stole the money and spent it. We have no way to verify it."

Zhou Changyuan cursed silently for a moment, then said, "If Yang Jianhui is innocent, in addition to theft, add another charge against him: destroying evidence at a murder scene. Prosecute him!"

"well."

It's no wonder Zhou Changyuan was angry. If fingerprints of both parties in the transaction could be extracted from the banknotes, and one of the fingerprints matched those under the bed and on the wall clock, then that person's activity trajectory would be completely clear, and there would be evidence to support it.

In other words, this person entered Yu Jing's room as a customer and paid her two hundred yuan in cash to have her take off her clothes.

Seeing that no one was speaking, Yang Jinwen continued, "After the victim, Yu Jing, took off her clothes, this person took out a steel wire rope and, taking advantage of her unpreparedness, put it around the victim's neck."

After being strangled, the victim was unable to make a sound and struggled desperately.

The murderer kept pulling on the steel cable, dragging her into the living room.

While in the living room, the murderer tripped and fell to the ground.

At that moment, he saw a small stool under the round table. He took the opportunity to take the stool out, placed it under the victim's head, and then used his knees to brace the stool and strangled the victim to death with all his might.

Looking at the photos of the body's wounds, there are obvious secondary ligature marks on the neck, and bruises on the victim's hands from grabbing.

In other words, the murderer used a steel rope to lasso the victim and strangled her the first time. The victim almost broke free. At that moment, the murderer may have fallen to the ground, and the victim caught her breath.

When the murderer strangled her a second time, the victim was unable to break free.

She was also experiencing urinary incontinence and was on the verge of death. After she died completely, the murderer used a cigarette butt to burn parts of her body, specifically her left and right breasts, and her abdomen…”

At this point, Yang Jinwen paused. The conference room was completely silent, except for the rain pouring down outside the window. The sky was very dark, accompanied by distant thunder.

Seeing that no one objected, Yang Jinwen continued, "The forensic doctor determined the time of death to be between 7:30 pm and 9 pm, so what time did the murderer actually commit the crime? We don't know."

However, it can be inferred that the murderer remained at the crime scene before 8:30 a.m., did not leave immediately, and continued to mutilate parts of the victim's body.

It was 8:30, just the time for Yang Jianhui to go upstairs.

It's highly likely that the murderer opened the door to leave at this moment, and just happened to run into Yang Jianhui appearing in the corridor.

At this point, the best course of action for the murderer is to close the door.

But Captain Fu and I both saw the door at the crime scene. It had a round lock with a rusty latch, and you had to slam the door shut to lock it.

In other words, the murderer had to slam the door shut.

But this would attract Yang Jianhui's attention, and the murderer couldn't determine who Yang Jianhui was. Perhaps he thought Yang Jianhui was a tenant on this floor, or perhaps the murderer, in his haste, quickly hid under the bed.

It was at this moment that Yang Jianhui discovered the door was unlocked, sneaked in, and saw the corpse.

Instead of calling the police, he stole the victim's gold necklace and money from the house, and then smoked a Baihongmei cigarette at the scene, throwing the cigarette butt on the ground.

After he left, the murderer emerged from under the bed, picked up the cigarette butt he had smoked, and stuffed it into the victim's body.

Another whiteboard contained photos of the body, one of which showed a cigarette filter still attached to the victim's body.

Fu Mingyuan pondered for a moment and said, "So, the murderer is trying to frame Yang Jianhui?"

Yang Jinwen looked at the forensic examiners and asked, "After you extracted the same fingerprints from under the bed and on the wall clock, did you find any similar fingerprints in other parts of the house?"

One of the technical police officers shook his head: "Apart from these two places, we have not obtained the same fingerprints from anywhere else."

Furthermore, we carefully examined the living room where the victim lay on the floor, as well as the small stool, and found traces of deliberate erasure.

Yang Jinwen nodded: "That's it. The murderer has dealt with the public security organs before, so this is definitely not his first crime."

After more than an hour of analysis, Yang Jinwen almost reconstructed the entire crime scene.

To reconstruct a crime scene, one needs to examine footprints and fingerprints. In the case of a heinous crime, one also needs to analyze the amount of bleeding, flow rate, and blood traces to determine the circumstances of the crime scene.

However, the victim in the 528 case died from mechanical asphyxiation and there was no bleeding. Therefore, based on the clues found at the scene, Yang Jinwen simulated the entire process of the murder.

It's like building a profile of the murderer in everyone's mind.

Zhou Changyuan pondered for a moment and said, "Captain Yang's analysis makes perfect sense. The murderer in the 528 case knew Yu Jing, so the murderer must have been to Hongyunlou before, or had contact with that Ji Xiaoqiang..."

Yang Jinwen quickly interjected to fill in the gap: "Director Zhou, it doesn't necessarily mean that you have to say you know her. After all, given the profession of the victim Yu Jing, she would probably open the door for strangers."

"Whether we know each other or not, the murderer must have found us through some means."

Yang Jinwen said, "Then it depends on whether the murderer premeditated the murder or just randomly selected a victim."

His meaning was quite clear: he was trying to link it to a serial murder case.

If it were a random killing, then this case would be huge.

Zhou Changyuan remained silent, since everyone knew that the murderer had not taken the victim's belongings after killing the person.

Why did the murderer kill?
A revenge killing? Or, as Yang Jinwen suggested, a random killing?
Lu Weiwei said, "Yesterday, Captain Yang asked me to interrogate Ji Xiaoqiang, and we got a list of regular customers from him."

Fu Mingyuan said, "This isn't the first time the murderer has been to Hongyunlou. He's between 1.65 and 1.7 meters tall, and he wears a metal belt buckle around his waist, which is worn. Director Zhou, I'll bring my men to investigate from this direction."

Zhou Changyuan, holding a pen, pointed at him and said, "This is not limited to Caochang Town; we need to investigate the entire county and all the coal mines."

As for distinguishing features, the suspect is between 1.65 and 1.7 meters tall, and his belt buckle is metal and has scratches. We've issued a request for assistance, asking all relevant departments to be on the lookout for individuals like this.

"Yes."

Zhou Changyuan narrowed his eyes, his expression serious: "In the investigation of criminal homicide cases, human life is of paramount importance! I don't care who it is, anyone who dares to obstruct our investigation will be arrested. That's what I said!"

Fu Mingyuan understood that the leader was endorsing Yang Jinwen, while also warning him not to "play along" with unrelated people. Just like yesterday's confrontation between Yang Jinwen and Ji Yuan from the Mining Bureau, Fu Mingyuan should have protected Yang Jinwen, but he didn't do it well enough.

He nodded quickly: "I know."

After the meeting, Yang Jinwen and the others put on their raincoats and followed Fu Mingyuan's criminal police team to Caochang Town again.

At this moment, the rain continued to fall, dark clouds rolled in the sky, and every now and then a bolt of lightning would flash, casting a white light.

Yao Weihua followed closely beside Yang Jinwen, wiped the rain off his face, and whispered, "Captain Yang, I've figured it out. What does the '5' on the clock face represent?"

"Representing 5 dead?"

Yao Weihua swallowed hard: "You think so too?"

Yang Jinwen climbed into the jeep and said worriedly, "I'm afraid there will be a sixth victim! Rainy days are perfect for murder."
