The crackdown on organized crime began with the arrest of the mother-in-law.

Qin Chuan's words left everyone stunned.

what happened?

How could the woman across the hall be the murderer?

The surrounding criminal police officers were all dumbfounded.

Based on the conversation between Qin Chuan and Lu Zhiguo, the deceased should be the male owner of room 302.

Yes, generally speaking, if one spouse is murdered, the other is always the police's primary suspect.

However, even if the other party is indeed the murderer, shouldn't we still investigate?

The key question is, why did the wife kill her husband not in her own home, but instead went to the house across the street?

Sun Haomin looked troubled when faced with Qin Chuan's order.

Listen to this, Qin Chuan has no evidence whatsoever, yet he claims the other person is the murderer.

If you don't listen, he's now the deputy captain in charge of the criminal investigation team.

How to do?

Fortunately, Sun Haomin wasn't the only one curious about why Qin Chuan said the woman across the hall was the murderer.

“Qin Chuan,” Zhou Xuexi’s words eased Sun Haomin’s embarrassment, “Why did you say that the lady across the hall is the murderer?”

"We rely on evidence when solving cases, not on guesswork."

If it were someone else, Qin Chuan might not necessarily explain, but Zhou Xuexi was his direct superior.

Qin Chuan is not afraid to confront Zou Mingyi, but he would never confront Zhou Xuexi.

Zhou Xuexi and Chen Mingguang are his biggest reliance for the foreseeable future, at least during his time working in Zhulin County.

Actually, when Qin Chuan was provoking Zou Mingyi, he wasn't just acting on impulse.

Although Qin Chuan is young, he has accumulated experience from his previous life and is no longer the kind of naive young man he once was.

There are several reasons why he made the bold claim of solving the case in a day in front of so many people.

First, Qin Chuan made a significant discovery after entering the scene.

To a typical criminal investigator, footprints at a crime scene can only provide some basic information.

But Qin Chuan saw it differently.

He possesses the skill of footprint identification, which he acquired through a system lottery.

This skill can help Qin Chuan determine basic information about the owner of clear footprints, such as height, weight, gender, and occupation.

With this crucial clue, Qin Chuan felt more confident.

This is his biggest advantage in daring to spend a day solving the case.

Secondly, Zou Mingyi's arrival was clearly for a purpose, and since the other party was not polite, Qin Chuan naturally did not need to be polite either.

Anyway, his promotion had nothing to do with the other party.

By taking advantage of the other party's lack of understanding of him, he managed to secure a collective second-class merit for the criminal investigation team, and he believed that no one in the team would dislike that.

This will greatly benefit my ability to establish myself in the criminal investigation team and build my authority.

Third, he did this in order to establish his image as a brilliant detective in front of Zhou Xuexi and all the members of the criminal investigation team!

The more outrageous your actions are, the less people will believe you. When the results arrive as promised, the contrast will be the greatest.

He wanted to gain Zhou Xuexi's trust and the trust of the criminal investigation team members as quickly as possible by solving the case!

It was based on these three considerations that Qin Chuan made the promise to solve the case in one day.

Now is the time to reveal the answer.

"Director Zhou, I've identified the woman in room 302 as the murderer, and that's based on the evidence!"

"Oh? Then tell me, what evidence led you to conclude that the other party is the murderer?"

Zou Mingyi also stepped forward.

They were clearly very interested in the evidence Qin Chuan mentioned.

"footprint!"

Qin Chuan answered loudly.

"The evidence that identified the female homeowner across the hall was the footprints left at the crime scene."

Qin Chuan explained as he walked to the door of room 301.

Pointing to dozens of chalk circles in the room, some overlapping and some standing alone.

"Look, everyone, all the places circled in chalk at the scene are the footprints left by the victims and the murderers."

Everyone present was a criminal police officer, although not all of them were crime scene investigators, but they all knew these basic common sense facts.

No one objected to Qin Chuan's words.

Even Zou Mingyi nodded in agreement.

However, due to the angle of the light, the shape of the footprints was not very clear.

"Um... is the on-site investigation and photography finished?"

what?

Seeing everyone's eyes on him, Song Yang awkwardly raised the camera in his hand: "Okay...okay..."

Damn, this is the first time the bureau chief has noticed me. Will I get promoted in the future?

After receiving an affirmative answer, Qin Chuan turned to another detective investigating the crime scene: "Did you bring magnesium powder?"

Chen Dejun nodded blankly: "In the site investigation box."

"bring here."

Qin Chuan took the magnesium powder, grabbed a handful, and flung it out.

Then, just as the magnesium powder was about to fall, he took out a match from his pocket.

chap!

A flash of light appeared, and a glittering beam of light flew by.

Everyone's eyes brightened.

When I opened my eyes again, I was surprised to find dark marks on the ground.

The footprints that were previously invisible were now clearly visible to everyone.

suck!

A gasp of shock rang out.

The weather in July should have been unbearably hot.

Everyone present felt as if they had eaten ice cubes, a chill running down their spines.

what's going on?

"Before the incident, the female homeowner of apartment 301 should have wiped the floor. After the footprints were left, the dirt on the floor could have absorbed the thin magnesium powder from the fire."

Damn...

How could we not know?

Song Yang and Chen Dejun exchanged a glance, feeling as if their field investigation skills had been wasted.

Qin Chuan didn't take it seriously; there were too many such tricks to obtaining criminal investigation scene investigations through the system's lottery.

However, this artificial development will destroy the original form of the footprints.

Therefore, before proceeding, he verified with Song Yang whether to take on-site photos.

Only after confirming that the other party had secured the evidence did Qin Chuan develop the film, making it easier for everyone to view.

"Look, everyone, all the footprints were left by three different kinds of shoes."

"The two footprints at the door belong to the female homeowner of apartment 301. After entering the apartment and discovering the deceased, she did not enter the house but left and called the police."

"The larger footprints in the room, with indistinct patterns, were left by the deceased wearing slippers."

"This can be confirmed by comparing it with the slippers on the deceased's feet."

"And the third type of footprint was left by the murderer."

"The shoe is 23 centimeters long, size 36, with a high inner arch and a low outer arch, and the center is forward. These are footprint characteristics that only adult women have."

"Stride length 43 centimeters, step angle 3 degrees inward."

"Based on the distance of the footprint's center of gravity offset, it can be calculated that the owner of the footprint was about 158 ​​cm tall, weighed about 45 kg, and was between 34 and 36 years old."

“When I went upstairs, the woman who lived in room 302 was at the door. Her height and weight information matched the footprint identification results perfectly.”

"Therefore, I conclude that the other party is the murderer!"
