I'm not a genius detective

Chapter 103 Intentional Injury Case

Trace evidence examination room.

Sun Yujie had dark circles under his eyes and said, "You front-line investigators are busy, but we technical squadron members are busy too."

The electronic evidence lab is working on computer vision technology, preparing to use computers to analyze video content. Once the image analysis team is established, they will focus on mastering this area.

Han Ling nodded.

In 2010, criminal investigation technology was already showing signs of rapid development. In a few years, the cost of committing crimes will increase significantly, making investigations more accurate and reliable.

"Do you need any help?" he asked.

Sun Yujie asked in surprise, "Are you really that free? Doesn't the First Squadron need you anymore?"

"No need to calculate it." Han Ling turned and left. "I'm going to take a stroll in the forensic lab."

Sun Yujie didn't care: "Go ahead, Yang Rui is busier, she doesn't have time to deal with you."

He continued working on the computer.

Since learning that Han Ling has a beautiful girlfriend, he no longer considers Han Ling a potential rival in love.

Upon arriving at the forensic lab, they happened to run into Yang Rui and her apprentice Qiao Hong, who were about to leave.

I thought I was going to deal with the intentional injury case from earlier, but when I asked, I found out that I was going to draw a family tree. Drawing family trees is one of the tasks of a forensic doctor.

The chief forensic pathologist and deputy chief forensic pathologist have already set off for the case of intentional injury.

Han Ling knew that the DNA database would prove its power in a few years, solving a large number of cold cases. Among them, a certain technology targeting male families played a huge role, and behind this was the hard work of countless forensic doctors.

They deserve respect.

Take care, you must be tired.

Han Ling waved from behind.

Okay, then I guess I'll just have to go back to the office for tea.

What's the difference between this and being suspended from duty?

……

Qingchang City People's Hospital.

Fangzhou arrived with his team. At that time, the victim was still undergoing surgery, and the local police station was waiting for the branch office to arrive to hand over the case.

The police station received the report at 7:40 a.m. The victim used his own mobile phone to make the emergency call and the police call, indicating that he was conscious at the time.

The hospital ambulance and the police officers from the local police station arrived at almost the same time.

When they arrived, the victim was lying in an empty alleyway, already in a coma and shock, and was in critical condition due to excessive blood loss.

Fortunately, he was still able to use his phone before losing consciousness, which saved him.

The woman, carrying a wallet containing her ID card, is named Xiao Yuxuan and is 27 years old.

The specific details are unclear.

The victim was seriously injured. After arriving at the scene, the local police station immediately reported the incident to the branch command center. At present, the scene has only been cordoned off and a preliminary investigation has not yet been carried out.

"He must have been stabbed three times," the deputy director of the local police station told Fang Zhou. "The doctor's assessment is not optimistic; his life may be in danger."

After learning the basic situation, Fang Zhou told Zhang Yandong and Tong Feng to wait at the hospital, and then led the other criminal police officers to leave the hospital and head to the scene of the incident to conduct an investigation.

Soon, Chief Forensic Pathologist Jiang Haichuan arrived and waited outside the operating room. Their task was to communicate with the doctors and review medical records, surgical procedures, and examination reports.

If possible, the victim should also be examined.

In forensic terminology, a dead person undergoes an autopsy, while a living person undergoes a live examination.

Even if the victim is admitted to the intensive care unit, the forensic doctor must examine the victim's injured parts as thoroughly as possible without affecting the treatment, and provide a report based on information such as the shape, size, and depth of the wounds to the front-line investigators.

If we wait until the victim leaves the intensive care unit, it will be too late, unless the investigators quickly identify the suspect.

The wait lasted three hours.

Xiao Yuxuan was wheeled out; she was currently under anesthesia and went directly to the intensive care unit.

This indicates that the victim's condition is serious and complex, posing a risk to their life, and requires 24-hour continuous close monitoring and intensive treatment.

After the doctor came out of the intensive care unit, Jiang Haichuan went up to find out what had happened.

Tong Feng also came over and listened attentively.

The general meaning is: there is a penetrating wound in the chest, which pierced directly through the lung lobe from the back, causing the lung to rupture and blood to accumulate in the pleural cavity, severely affecting breathing.

At the same time, the knife tip also cut the pericardium, and the blood accumulating in the pericardial cavity compressed the heart, which is one of the life-threatening injuries.

In addition, there were puncture wounds in the upper right abdomen and stomach.

The victim currently requires a ventilator to assist breathing and is being treated with potent antibiotics and vasoactive drugs to maintain vital signs.

Tong Feng didn't understand the medical terminology and only focused on the key points. As a result, even if the victim's injury was minor, it was still considered a serious injury. If the victim died in the intensive care unit, it would be a murder case.

"What kind of deep-seated grudge is this?"

As Tong Feng pondered this, he caught a glimpse of Xu Qinghe, who had taken off her mask, not far away.

Ok?
He waved gently at the other person.

Xu Qinghe saw him and walked towards him: "Where's Han Ling?"

Tong Feng: "You're only thinking about your boyfriend, right? He's at the branch office; the team has arranged other work for him."

Xu Qinghe responded with an "oh," indicating that the other party still believed she was Han Ling's girlfriend, suggesting that Han Ling had not denied the rumors at the branch office.

Perhaps, like her, being in a relationship would save a lot of trouble. Since that conversation at the Western restaurant, she dared not be so aggressive towards Han Ling anymore; being natural was better.

Han Ling was comfortable, and so was she.

We'll see what happens next, one step at a time.

"You were also involved in the surgery?" Tong Feng asked.

Xu Qinghe nodded: "The injured person's condition is quite complicated and requires consultation from multiple departments. Besides, I am from the emergency department and was the first to come into contact with the injured person."

Tong Feng nodded and pointed to the intensive care unit: "She should be alright, right?"

Xu Qinghe replied, "It's hard to say. It depends on how well she recovers and whether her injuries will worsen in the short term. As long as she can get through the next 24 hours, she should be fine."

The pericardium was punctured; that alone meets the criteria for serious injury. You need to have it checked as soon as possible.

Tong Feng was surprised: "You also know about forensic identification?"

Xu Qinghe smiled: "Doctors and forensic doctors have many areas of overlap."

Tong Feng praised, "You're really amazing. I wish you were a forensic doctor. If you joined our technical squadron, you'd be seeing Han Ling every day. How sweet that would be!"

Xu Qinghe did not respond, politely said goodbye and left, as she still had follow-up work to do.

"Can we go in now?" Jiang Haichuan asked the doctor on the other side.

After thinking for a moment, the other party said, "Let's wait a bit longer. Her condition is very unstable right now. Let's talk about it once she's more stable."

Jiang Haichuan: "Okay, let's take a look at the surgical records."

He didn't insist. In medical matters, one should listen to professional doctors. If the forensic examination worsens the victim's injuries, it would be a real loss.

Doctor: "Okay, please follow me."

Jiang Haichuan nodded slightly to Tong Feng and Zhang Yandong, and then followed the doctor.

The police officers from the local police station had already left to assist the criminal investigation team in their investigation. At this moment, the hospital corridor was empty, with only Tong Feng and Zhang Yandong remaining.

Before the new orders arrive, the two need to stay outside the intensive care unit. The victim's condition is crucial to the case investigation and directly affects the nature of the case.

……

The scene of the incident.

There were no surveillance cameras nearby, so the suspect chose a very good spot to make his move.

As the investigation progresses, Fang Zhou is currently reviewing surveillance footage at a nearby internet cafe, which is only about 50 meters from the scene of the incident.

After interviewing people in the surrounding area, it has been confirmed that the victim, Xiao Yuxuan, entered the internet cafe at around 4 a.m. and left at 7:30 a.m.

Xiao Yuxuan left the internet cafe at 7:30, and the police station received a report at 7:40. This means that she was stabbed by the suspect shortly after leaving the internet cafe.

The phone and wallet were both there, so it wasn't a robbery or assault; the most likely explanation is revenge.

"Follow the direction Xiao Yuxuan came from to the internet cafe and see where she went before," Fang Zhou ordered.

The fact that a young woman was still wandering around outside at four in the morning is itself abnormal.

"By the way, have you contacted Xiao Yuxuan's husband yet?" Fang Zhou asked.

Xiao Yuxuan's basic information is now clear: she is from out of town, has a bachelor's degree, is married, and is currently unemployed.

The criminal police officers in the squadron have called Xiao Yuxuan's husband, Dai Bin, three times, but no one answered each time, and they don't know what he was doing.

"Not yet," the officer replied.

Fang Zhou: "I asked the police station staff to go to his house and check on him. His wife was wandering around outside in the early hours of the morning, and we couldn't reach her by phone. What was he up to?"

Police officer: "Okay, squad, I'll talk to the police station right away."

It was already noon, and there was no time for lunch. I was so hungry that I could only buy something from a roadside vendor and eat while I worked.

The street where the incident occurred is an entertainment street in Qingchang. In addition to internet cafes, there are also bars, KTVs, billiard halls, audio-visual stores, ice skating rinks and other places. The police officers checked the surveillance footage based on the direction the victim came from and eventually found a nearby disco.

The disco is open from 7:30 pm to 2 am, but it is closed now.

Although the store was closed, the staff were still there, and Fangzhou knocked on the door.

"Hello, criminal police officer from the branch office, is your boss here?" Fang Zhou showed his identification.

Upon seeing the police arrive, the staff immediately became nervous and rushed to call the boss.

Those who work in entertainment venues least want to deal with the police, because if you want to make more money, you can't possibly follow the rules; you always have to break the rules and skirt the edge.

If they really wanted to take you down, a little investigation would force you to shut down and rectify the situation; no entertainment venue is exempt.

Upon learning this, the boss rushed over and politely invited Fang Zhou and the others into the disco.

He was very experienced and knew that the detectives were definitely not there to investigate, so he wasn't flustered.

They're investigating big cases; they don't have time to deal with the operation of entertainment venues.

"Are all the surveillance cameras there?"

Fangzhou inquired, his gaze sweeping over the disco environment.

The decor is stylish and cool, with lots of lighting and mirrors. There's even an LED screen over the dance floor. You can imagine how visually impactful it must be at night.

The venue was open to the public until 2 a.m., but the victim, Xiao Yuxuan, and other customers left at 4 a.m., which constitutes operating beyond the permitted hours and violates the regulations governing entertainment venues.

This matter is outside Fangzhou's responsibilities, at least for now, he won't cause trouble for the boss.

The phenomenon of operating beyond permitted hours is prevalent throughout Qingchang. There's a reason for its existence. Internet cafes are prohibited from staying open all night, but which internet cafe doesn't stay open all night?
