Major Crimes Unit Starts with Police Academy Students

Before Professor Wang Jiancheng could finish speaking, Wu Mingcheng had already put down his pen, capped it, and returned it to its original place.

"Teacher, I've finished writing."

At this moment, in the eyes of his many female admirers, Wu Mingcheng exuded an air of confidence and radiated intelligence.

They thought Wu Mingcheng was incredibly handsome, so good-looking and so talented—a real gem!

Professor Wang Jiancheng was still somewhat surprised, even though he knew how abnormal his student was.

Reasoning is essentially all about technique, and the knowledge required in the process is incredibly diverse.

Even seasoned criminal investigators who have worked on the front lines for many years need to continuously keep up and learn.

Even the best person in the Criminal Investigation Bureau that year couldn't match Wu Mingcheng's speed when solving this problem.

Professor Wang Jiancheng glanced at Wu Mingcheng, then turned his attention to the reasoning on the question board.

It's often said that laymen watch the spectacle, while experts see the details. Given Professor Wang Jiancheng's authority in criminology, he could instantly discern a reasoner's true skill level.

I must say, without my knowledge, this student's abilities in all aspects have improved again.

Professor Wang Jiancheng then addressed the audience.

"Alright, let's all take a look at Mingcheng's reasoning process together, and then point out any errors and discuss it."

At the same time, I also hope that everyone can gain something from this process.

He then carefully examined the reasoning that Wu Mingcheng had written on the question board.

The more he read, the more he admired Wu Mingcheng.

From a crime-solving perspective, the time of the crime is usually considered first, but the motive for murder is also an indispensable factor in the investigation process.

According to Wu Mingcheng's reasoning, both suspects are possible perpetrators.

Therefore, only by finding the exact time of the victim's death can we determine who murdered the widow based on the alibis of both individuals.

The starting point for reasoning in the Wu Mingcheng case was clearly well done.

What surprised Professor Wang Jiancheng most was that Wu Mingcheng's analysis of the timing of the crime was also incredibly accurate.

This point truly impressed Professor Wang Jiancheng, who admired his student.

Because some frontline detectives who frequently solve cases sometimes have to rely on high technology to determine the time of death.

Professor Wang Jiancheng was also very curious about how Wu Mingcheng determined the time of death.

So he asked,

"Mingcheng, tell everyone why you determined the time of death to be at night?"

Wu Mingcheng said,

"Okay, teacher, it's because of this photo that this is a key point."

Take a closer look at this photo, everyone. What do you notice in it?

As he spoke, he pulled the photograph from under the colored magnet and placed it in his hand.

Then he held the photo up in front of everyone so that everyone could see it clearly.

Some students sitting further back took out their phones to zoom in and take pictures, then carefully examined the photo.

Everyone knows that the murderer put the body in hot water to conceal the true time of death.

But Wu Mingcheng brought up this photo, which has left many people puzzled.

At this moment, a student in the audience couldn't help but ask a question out of curiosity.

"Senior Mingcheng, is there anything different about this photo?"

"It's just a few feathers stuck to a spider web outside the second-floor window, isn't it? We don't quite understand,"

A master's student in the second row also spoke up.

"Yes, the investigation results for this question stated that the crime scene was found in the second-floor bedroom."

There were signs of a fierce struggle, and the feather pillow was torn.

The room was covered in white feathers, with a few occasionally drifting out the window. Was there anything unusual about this?

Wu Mingcheng did not rush to answer their questions, but instead gave them time to think.

All the students in the lecture hall began exchanging ideas with their classmates, discussing in hushed tones.

I asked one of Yu Xi's roommates,

"Yu Xi, can you see anything wrong?"

Xiang Yuxi shook her head and said,

"Based on the description of the case, the picture is indeed reasonable, and I don't see anything wrong with it,"

The group discussed it quietly for a long time, but ultimately no one could come up with a satisfactory answer.

The middle-aged man sitting in the last row of the lecture hall also looked at the photo that Wu Mingcheng was holding.

He looked at it carefully, seemingly lost in thought. Suddenly, it was as if he had just realized something, and a clue flashed through his mind.

Chapter 20 The Key Spider

Professor Wang Jiancheng smiled at this moment. As the one who set the question, he certainly knew that this photograph was the key to solving it.

Wu Mingcheng immediately found the key to solving the case.

This truly made Professor Wang Jiancheng very satisfied with this student.

Others, however, lacked the necessary abilities in various aspects and didn't reach that level, so they couldn't discern anything at all.

Then Professor Wang Jiancheng spoke up.

"Mingcheng, it seems that many people don't quite understand. Could you explain it to them in detail and clear up their confusion?"

Wu Mingcheng nodded, smiled slightly, and said,

"There might be a misunderstanding; people have focused their attention on the rather conspicuous feathers in the picture."

However, what I want to say is that the key issue isn't the feathers, but the spider on the tree outside the window.”

Hearing Wu Mingcheng's words, many people asked in confusion,

"Spiders? What about spiders? What does the time of the crime have to do with spiders?"

This left all the students in the lecture hall even more confused and bewildered.

Wu Mingcheng continued speaking,

"Actually, all the items at the crime scene can talk and tell us other information."

"I determined the crime occurred at night, and it was this inconspicuous spider that told me that,"

At this moment, a student in the front row spoke up.

"What? Spiders can talk? I don't believe it!"

A PhD student nearby was eager to know the answer.

She quickly spoke up.

"Mingcheng, stop keeping us in suspense and tell everyone what you know,"

Professor Wang Jiancheng on stage also smiled and said,

"Alright, Mingcheng, now it's your turn to unravel the mystery for everyone,"

Wu Mingcheng smiled calmly, and then said,

"The spider on the tree played a crucial role in solving the case."

Based on the comparison of its appearance, I knew it was a tarantula about thirty centimeters long.”

At this moment, people below muttered to themselves,

"A tarantula? What's that? I've never heard of it."

Wu Mingcheng then spoke up to explain to everyone,

"Some people may not know about this tarantula. Tarantulas have three types of habitats: terrestrial, arboreal, and burrowing."

The tarantula in the photo is clearly arboreal, and its venom is much stronger than that of ordinary spiders.

They rely on venom to kill their prey that falls into the net before eating it.

Then, he held up the photo in his hand, pointed to the feathers in the photo, and said,

"And on the spider's tattered web, there were remnants of white feathers from its feather pillow."

Because tarantulas are mostly nocturnal, they often weave their webs at dusk and then tear them apart the next morning.

From this, I can conclude that the murderer committed the crime at night.”

After Wu Mingcheng explained it this way, everyone quickly understood how to determine the time of the crime.

The fact that feathers could stick to a damaged spider web suggests the crime occurred at night.

At the same time, everyone was inwardly marveling, "Wow, that's Wu Mingcheng for you! He's amazing!"

They're only scratching the surface of the case; others can clearly identify the species of spider.
