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

Chapter 384 Witness!

December 8th and December 9th passed in two consecutive days.

The investigation is proceeding intensively, radiating outwards from the crime scene with a radius of three kilometers.

Within a kilometer, there is only the Hongxing Brick Factory.

The investigation of the area around the brick factory was completed the day before yesterday afternoon.

At the time of the incident, apart from the truck driver and two loaders who discovered the murders of Li Song and Fan Chuanping, the workers at the brick factory did not find any suspicious persons, nor did they hear any gunshots at the time of the incident.

In other words, no one within a kilometer witnessed the two criminals committing the crime, nor did they know the direction they fled.

On December 9, the investigation continued for the next two kilometers, entering a residential area where buildings and people were densely packed, which slowed down the investigation process considerably.

But everyone knows that if the two criminals fled on foot after killing the person, then someone must have seen them.

In addition, with sketches of the two criminals and the kidnapped old lady in hand, it's only a matter of time before they are identified.

In order to save time, Wen Mo dispatched two additional joint defense teams on the morning of December 9, increasing the number of people conducting the investigation to more than 12.

Li Song was shot and killed instantly; the bullet struck his heart. Therefore, the time of his death coincides with the time the two assailants fled.

On the afternoon of December 9, Wen Ling and Jiang Yuxin arrived from An'nan City to report for duty. Without a moment's rest, they immediately conducted a second autopsy on Li Song's body.

The time of Li Song's death was determined to be between 4 and 5 p.m. on December 7.

Therefore, if the perpetrators had no means of transportation to pick them up, there must have been eyewitnesses who saw them on a street or alley about a kilometer away between four and five o'clock.

They might walk or take public transportation, and they will definitely leave traces of their movements.

At this moment, in the autopsy room of the funeral home.

Wearing a white coat and a disposable blue cap, Wen Ling performed an autopsy on the second victim, Fan Chuanping.

The time of Fan Chuanping's death cannot be used as a reference in the case; the main focus is on finding the cause of death and the type of murder weapon.

The stab wounds were concentrated in the upper abdomen, indicating that the murderer's sole purpose was to kill.

Under the white spotlight.

Wen Ling's voice came from behind the mask: "The first wound is five to six centimeters deep, piercing the pleura and the apex of the lung."

Below is the pulmonary hilar blood vessel. If the pulmonary hilar blood vessel is punctured, the survival time is at most half an hour, and death may occur within twenty minutes.

The primary cause of death was a puncture of the pleura, which caused the loss of negative pressure in the pleural cavity, lung collapse, a decrease in ventilation area, and a sharp drop in blood oxygen saturation.

The patient lost 600 milliliters of blood, and the emergency surgery was very difficult; the patient could not be saved.

If the blood loss is 1500 ml, the survival time is at most eight minutes; if the intercostal artery is ruptured, death will occur in three minutes.

The most serious injury is to the heart, and the patient's survival time is only about one minute.

In other words, the deceased would not have survived if he had not received adequate medical care and had had time to be rescued after being stabbed for the first time.

The second and third wounds, between the lung and the heart, were stabbed to a depth of about four to five centimeters. They were not fatal, but the two wounds were very close together…

Wen Ling paused at this point.

Jiang Yuxin asked, "Sister Ling, what does this mean?"

Wen Ling sighed, and Yang Jinwen, who was standing behind her, analyzed: "This means that when the murderer stabbed Fan Chuanping for the first time, he had already found the vital point."

When he was stabbed a second and third time, the wounds were very close together, indicating that after the first stab, the other assailant immediately restrained him or held him down to prevent him from resisting.

Furthermore, Fan Chuanping had already been stabbed once and was unable to resist, which is why the assailant stabbed him twice in the same spot!

Looking at the young corpse on the autopsy table, Maozi sighed slightly and said, "In other words, Li Song was driving at the time, and by the time he realized what was happening, the two murderers had already completed this series of killings."

Then, a struggle broke out inside the car. Li Song turned the steering wheel around and drove the van off the road. The two assailants took the opportunity to get out of the car and escape. Li Song chased after them and was then shot dead.

During this time, Fan Chuanping was still alive and wanted to get out of the car to help, but he had been stabbed three times and was powerless to do anything.

That's why his bloody handprint was left on the car door!

Wen Ling nodded and took off her mask: "Judging from the shape and depth of the wound, it was a single-edged knife."

Yang Jinwen asked, "What kind of knife specifically?"

Li Yuanquan frowned: "What kind of knife is this again? It doesn't look like a typical killing weapon, nor like a fruit knife, nor like a dagger."

"Captain Yang, we can make a mold, which would be more intuitive, but it will take several days."

Wen Ling pondered for a moment and said, "We definitely need to make a mold, but the shape of the wound looks a lot like a Bowie-shaped knife tip."

The cat blinked: "What is a Boy shape?"

Li Yuanquan looked at Wen Ling in surprise. A few days ago, he had praised Wen Ling to Wen Mo. In fact, he knew that Wen Ling was quite capable. After all, Wen Ling's grandfather was a senior forensic doctor who had been affiliated with the provincial department.

She herself is a top student from the Public Security University, so her knowledge is undoubtedly excellent.

Li Yuanquan wasn't making baseless accusations, but he didn't expect Wen Ling to have such a broad knowledge base, able to immediately describe the characteristics of the murder weapon.

Wen Ling asked, "Do you know about Boyi Knife?"

The cat shook its head.

Wen Ling took off her gloves, found a pen and notebook on the counter, and drew several knife shapes.

"The first type is a sword-shaped blade tip, which has strong piercing power but weak slashing ability."

The second type is a teardrop-shaped blade tip. The blade tip is shaped like a teardrop with a larger angle. This larger arc blade tip is very convenient for cutting and peeling, but relatively speaking, its piercing ability is weaker.

The third type I drew is the Bowie point. Compared to the sword point, the Bowie point improves the knife's cutting ability without sacrificing its piercing function. For those who want to both pierce and chop simultaneously, the Bowie point shape is the best.

Yang Jinwen squinted: "So, this kind of knife is specifically designed for hand-to-hand combat?"

Wen Ling nodded: "That's right, this kind of dagger is commonly used in the army."

The cat was startled: "Could the murderer be...?"

Yang Jinwen waved his hand, and Maozi quickly shut up.

Li Song was assigned to work at a shelter after being discharged from the military. If the murderer was also a veteran...

At this moment, Wen Ling shook her head: "You can't think like that. Outdoor enthusiasts and martial arts lovers all like Bowie knives. This kind of knife has a wide range of uses." Maozi nodded: "I know that. Those hooligans outside like to use butterfly knives to scare people."

As she said this, the cat flicked her wrist: "Swish, swish..."

Jiang Yuxin looked at her brother with disdain, feeling somewhat ashamed.

She was able to come to the provincial capital to work with Wen Ling, which was indeed thanks to Wen Ling's help.

Wen Ling could have easily brought Zhang Lei, a more experienced martial arts fan, to the provincial capital, but Zhang Lei still hasn't finished reading the book on forensic anthropology that Wen Ling asked him to read. Instead, he has read all the novels by Jin Yong, Gu Long, and Huang Yi.

So Wen Ling abandoned him, leaving him to drift through life in An'nan City.

At this point, Wen Ling put on gloves and, with Jiang Yuxin's assistance, continued to dissect Fan Chuanping's body.

Outside the autopsy room, Wu Daqing jogged in and said to Yang Jinwen, "Captain Yang, we have a lead!"

Yang Jinwen turned to look at him: "What clue?"

"The joint defense team found an eyewitness on Xinpu Road. The eyewitness said that he saw the red Buick around 3:30 pm on December 7th, as well as two thugs and Li Song and Fan Chuanping."

Holding the scalpel, Wen Ling raised her face, looked at Yang Jinwen's departing figure, and shook her head slightly.

Jiang Yuxin called out, "Brother, be careful."

The cat didn't turn around, it just waved its paw.

Although Jiang Yuxin called out to him, her eyes were fixed on Yang Jinwen's back.

Wen Ling glanced at her: "Stop looking, bring the chest expander and open up your chest cavity!"

"Okay, okay." Jiang Yuxin hurriedly lowered her head and frantically searched for tools.

May 10, 10:00 AM.

In front of a supermarket on Xinpu Road.

Several members of the joint defense team surrounded a short man.

As soon as Yang Jinwen and his team arrived, the joint defense team members quickly dispersed.

After Maozi showed his identification, Yang Jinwen looked at the most timid person.

"What's your name?"

"Boss, you can just call me Lao Lu."

One of the young men in the joint defense team, wanting to show off, yelled, "What are you afraid of? The leader told you to use your real name."

"My name is Lu Ping."

Compared to the criminal police, the other party seemed more afraid of these members of the joint defense team.

Have you ever seen a red Buick with a license plate ending in 3?

"Yes."

What month and what day?

"December 7th afternoon."

"What time is it?"

Around 3:30.

"How do you know so much?"

"That afternoon, the food factory's small truck happened to be delivering goods to me, and the delivery driver and I were moving the goods into the supermarket."

Who did you see?

"Those two people in the portrait."

"Are you sure it's them?"

"That's right, I wouldn't dare to lie."

Yang Jinwen took out photos of Li Song and Fan Chuanping and handed them to him.

"You've seen these two people before?"

The supermarket owner turned to the side and pointed to the road ahead: "Over there, I saw the two people in the photo stop the two people in the portrait. The four of them confronted each other for several minutes, and then got into a silver van."

Which direction did they go?

"After getting in the van, it drove away along Xinpu Road."

The road he mentioned, after you turn right, drive for half a kilometer, then turn left again, that's the dirt road to the Red Star Brick Factory, the place where Li Song and Fan Chuanping were murdered!

Where did you see that red Buick?

"Look, it's that alley. I was unloading goods when I saw a red Buick drive into the alley. Less than ten minutes later, the two men in the portrait came out of the alley."

"The people came out, but the car didn't?"

"Yes, these two walked forward for less than two minutes after they came out of the alley."

The silver van suddenly stopped beside them.

Two people got out of the car—the two people in the photo. They stopped the two people in the portrait, and almost got into a fight.

Yang Jinwen looked up at the alley ahead. At the entrance of the alley stood a row of cement utility poles, with a square road sign nailed to each pole that read "San Gong Alley".

He squinted and asked, "Has it been checked over there?"

One of the deputy captains leading the joint defense team shook his head: "Not yet."

"Let's go and see."

Yang Jinwen stepped towards Sangong Lane and reached out to lift the back of his clothes.

Upon seeing this action, Wu Daqing immediately tensed up. Last time, when Captain Yang fired a shot, he had also lifted his shirt beforehand!
　I was quite busy the past few days, with too many things to do at home. Six people from my parents' family came to visit, and I had to entertain them. I was thinking of asking for leave, but I decided against it. Everyone commented that there were many typos, which I will correct in each chapter from now on.
