Chapter 12 Site Investigation Report

"Master, what should we do next?" Chen Yan asked.

Wu Yongcheng stretched and said, "Go to sleep."

"Sleep?" Zhou Yi and Chen Yan were both stunned.

"Look at the heavy rain outside the window. I don't think it'll stop anytime soon. Why don't we take a nap first, recuperate, and then we can get back to investigating the case."

Chen Yan leaned over to the glass window and took a look. The rain was indeed heavy, pouring down.

Fortunately, the crime scene and the body have been inspected, otherwise all clues and traces would be lost after such a heavy rain.

"Okay, Xiao Chen, take Zhou Yi to the lounge for a nap."

"Master, you should go get some sleep. I'll keep an eye on it, just in case the hospital calls you if they have any clues."

"It's okay, I smoked too much and I'm feeling energetic now."

Wu Yongcheng waved his hand and said, "Go ahead."

Seeing this, Chen Yan asked Zhou Yi to follow him.

As soon as he walked out of the office, Wu Yongcheng asked, "Zhou Yi, how were your grades in the police academy?"

Zhou Yi scratched his hair and said, "It's okay."

"Has anyone ever taught you how to investigate a case? I don't mean in textbooks."

Zhou Yi knew what he wanted to ask, so he replied, "Yes."

"who?"

"God, he said I was a detective in my previous life, so I have to be a detective in this life too."

…

Zhou Yi woke up after sleeping for about an hour and a half.

It’s good to be young. You will feel refreshed after a short sleep.

He hasn't felt this way in a long, long time.

"Time is merciless." Zhou Yi sighed in his heart.

"Awake?" Wu Yongcheng's voice suddenly sounded behind him, startling him.

"Captain Wu?" Zhou Yi sat up from the narrow wooden bed.

Wu Yongcheng walked to the window of the lounge and reached out to pull open the smoke-yellow curtains.

A cold white light shone in, and Zhou Yi couldn't help but reach out to block it.

Zhou Yi noticed that Wu Yongcheng's eyes were red, apparently from staying up late.

Thinking back to the time, I also worked so hard.

But in the end, he still lost to someone else's backing.

But it’s just as well this way, because he has always lived up to the national emblem on his body.

"Captain Wu, are the test results from Forensic Doctor Xu out?"

"Yeah." Wu Yongcheng reached into his pocket but felt nothing.

No more cigarettes! Damn it!

"Is it okay?" Zhou Yi asked.

"You think there's something wrong with you so you can just lie here and snore?"

"That's fine." Zhou Yi stood up and said, "Then I'll go investigate the case?"

"etc."

"Captain Wu, what are your instructions?"

"Have breakfast first, then go. Xiao Chen is going to buy it."

"Oh." Zhou Yi sat down again.

At the same time, Wu Yongcheng threw a stack of information in front of him.

"Eat while you read it, and then tell me how you plan to investigate it."

Zhou Yi nodded, and two minutes later Chen Yan came in carrying a bag of buns and a thermos filled with steaming soy milk.

Chen Yan's eyes were also red, but he was young after all, and looked much more energetic than Wu Yongcheng.

Zhou Yi ate while reading the information. He was familiar with most of it, but there was something more than before, namely the on-site investigation report.

In addition to routine inspections, there are two points that are quite valuable.

The first point is the bloodstains. The bloodstains distributed at the scene showed the path the deceased took while struggling to escape, but the amount of blood in these bloodstains verified Zhou Yi's previous judgment.

The carotid artery was the first stab wound, and the following stab wounds were intentional after the victim fell to the ground.

Because the initial amount of bleeding is very large and splashing.

If the victim was stabbed first with a non-fatal wound, and then fled, and the murderer chased after him and continued stabbing, slicing the carotid artery in the middle, the initial amount of blood would not be so large, and the blood would not be splattered.

So when Zhou Yi said that the carotid artery was the first cut, Wu Yongcheng immediately thought of this, but the technical department had not yet issued the investigation report.

Zhou Yi's words broke his inherent thinking and was one of the reasons why he was attracted to talents.

On-site investigation is a very objective and accurate description of the facts, but drawing conclusions based on the facts is the job of the criminal police handling the case.

This can only be achieved with extremely strong observation skills and rich experience. Wu Yongcheng had to admit that he didn't even notice it.

Of course, with his personality, it is impossible for him to praise Zhou Yi.

The second point is footprints.

A total of twelve different sets of footprints were found within twenty meters of the scene, but based on the comparison of the depth and coverage of the footprints, only three sets were left within the time period of the crime.

One group is number 36, belonging to the deceased; the other group is number 45, belonging to Zhou Yi.

There is another set of footprints with a size of 42.

This size is a bit awkward, it could be for men or women.

If it is a woman, then her height should be around 1.7 meters, and her physical features will be more obvious.

However, judging from the pattern on the soles, it is more likely to be men's sneakers.

So when Zhou Yi said that the murderer might be a woman, Wu Yongcheng did not quite agree.

"Captain Wu, I've finished reading." Zhou Yi said vaguely as he stuffed the last bite of bun into his mouth.

"Any ideas for solving the case?"

"I think we can further narrow the scope of the investigation. The murderer should be a colleague of the deceased in the hospital."

"Why?"

"Du Xiaolin's home is about three kilometers away from the Third Municipal Hospital. For a normal young woman, this distance would take about forty minutes on foot."

Zhou Yi tapped the information and said, "This is quite abnormal."

"On paper, three kilometers doesn't seem like a long distance, but it takes 40 minutes to walk home from get off work. Is that reasonable? And in the middle of the night."

"Why doesn't Du Xiaolin ride a bicycle?"

Chen Yan said, "Maybe she doesn't know how to ride a bike?"

"Okay, let's assume Du Xiaolin doesn't know how to ride a bike. The day shift nurses get off at 4 p.m., and the night shift nurses get off at 8 a.m. Both times are open to taking the bus."

"There are no buses left after the midday shift. Why don't my family members come to pick me up?"

"The on-site investigation report did not mention any traces of bicycles, and no discarded bicycles were found at the scene."

"From the moment I arrived at the crime scene, I could tell that Du Xiaolin wasn't completely dead. It's basically confirmed that she walked home last night."

Wu Yongcheng, who had been listening to Zhou Yi's analysis, asked, "How does this connect to the fact that the murderer was a colleague at the hospital?"

"Who knows Du Xiaolin's work schedule? Who might know the route Du Xiaolin must take to get home? Who is most likely to have tampered with the situation, causing Du Xiaolin to have to walk home yesterday?"

Zhou Yi said solemnly: "Apart from her colleagues, I can't think of any other possibilities."

Wu Yongcheng nodded and said, "The hospital and the relationship with colleagues are one of the key areas of investigation, but other areas cannot be ignored either. So, your grandfather is in the hospital, right? As the patient's family member, you should go and get some information and see if there are any valuable clues."

"But you have to remember that you can't just investigate the case in the name of the police. You should understand the procedures."

Zhou Yi nodded. The procedure Wu Yongcheng mentioned meant that under normal circumstances, two people must handle the case.

Although the Criminal Law does not have clear provisions, from the perspective of fairness, safety and legality, this is the default routine procedure within the public security system. It also plays a role in mutual supervision to avoid favoritism and abuse of power.

"Captain Wu is really thoughtful. I will just chat with the medical staff as a patient's family member, just a simple chat." Zhou Yi smiled cunningly.

Wu Yongcheng nodded with satisfaction. This kid is indeed very smart.

"By the way, don't alert the enemy," Wu Yongcheng warned.

Zhou Yi immediately said, "I'll handle this with discretion, Captain Wu, don't worry. The murderer definitely isn't someone who worked the night shift last night. After all, they have a solid alibi."

Zhou Yi turned to Chen Yan and said, "Oh, by the way, Brother Yan, I'll have to trouble you to go back to the hospital security department to retrieve the emergency department's personnel files. I can't handle this."

Chen Yan nodded.

"And there's more..."

"What?" Chen Yan asked curiously when he saw that he was acting mysteriously.

Zhou Yi smiled and said, "Buy a pack of cigarettes for Captain Wu."
