Hong Kong movie: I show my cards, I am the best brother in the police force!

They are two women and three men!

However, Lin Jun did not interrogate them, but investigated fingerprints.

Soon, he found out from the bank clerk's spare fingerprints that the three had touched the fire extinguisher.

Lin Jun questioned them one by one, and to Lin Jun's disappointment, the three of them had all touched it a few days ago.

When Lin Xisheng died, they were all at their jobs, and eyewitnesses grabbed a lot of them.

There was no time to commit the crime at all.

After checking this, Lin Jun knew that it was impossible to find out the prisoner by relying on fingerprints.

Because the prisoner was very cautious, he must have worn gloves when committing crimes.

Since it is not possible to pass fingerprints, Lin Jun can only rely on monitoring.

"It's the five of them?"

Lin Jun looked at the five bank clerks in front of him who were a little panicked, and asked Ma Jundao.

"Yes!"

"In accordance with your instructions, we have checked all the people who have entered and exited the stairwell on the fifth floor of the crime scene during that time period. "

"There were five of them. "

Although Lin Xisheng died on the eighteenth floor, it is not certain that the murderer also entered and exited on the eighteenth floor.

It is also completely possible on other floors, so Lin Jun let Ma Jun.

Find out all the people on the upper and lower floors in that short period of time.

There were five of them.

"You come with me first. "

Lin Jun took the lead and pointed to a man.

There were men and women inside, but that was just for the sake of caution.

In fact, according to Lin Jun's guess, the murderer should be a man.

After all, the fire extinguisher is not light, and it is difficult for ordinary women to pick it up and hurt others.

"What are you going to do in the stairwell?"

Coming to the conference room that had been requisitioned, Lin Jun asked directly.

"Things don't go well at work, so I want to breathe. "

The man replied cautiously.

"Can you tell me what's going wrong?"

Lin Jun asked him as he used the universal data system to detect his heartbeat.

As long as he lies, he will not be able to hide the universal data system.

The man naturally said what he encountered at work, and after a client fund lost money, he was vexatious and vexatious.

His heartbeat, as well as his temperature, were normal.

Lin Jun asked the police officer to verify his colleague, and he was not lying.

Recently, there is indeed a customer who has been looking for trouble with him, and he has also complained to his colleagues around him for a long time.

His suspicion was temporarily ruled out.

Lin Jun called a second man, and the man had a strong smell of smoke, and he looked like a smoker.

"Tell me, what are you doing in the stairwell?"

"Smoking!"

"Is it just smoking?"

The universal data system found that the man's heartbeat in front of him was abnormal, and now he was lying.

And he smiled very reluctantly: "I used to go to the stairwell to smoke, and my colleagues know that I have this habit." "

"Sir, if you don't believe it, ask my colleague. "

Lin Jun didn't believe his lie at all, but said coldly: "I'll give you another chance one last time!"

Hearing Lin Junsenran's courage, the man suddenly pondered with a frightened expression.

After a long while, he cringed and said, "Sir, if I say it." "

"I hope you can keep it my secret. "

Lin Jun nodded and said, "Okay, you can say it!"

The guy said cautiously: "Actually, I went on a date with Ah Fang." "

"Office romance?"

Many companies don't allow office romances, which can affect productivity.

"Not ......"

The man shook his head.

Seeing his cringe-cateing expression, Lin Jun immediately understood.

It turned out to be stealing.

"Alright, I got it, go ahead. "

Lin Jun said helplessly.

I didn't expect this kind of thing to be found out in the murderer's case, and I can only hope that the person with the green grassland on his head will be strong.

The man was still a little incredulous, and when he saw that Lin Jun's expression was wrong, he hurriedly left.

Before leaving, they didn't forget to tell Lin Jun to keep it a secret for them.

Lin Jun and Ma Jun glanced at each other, and they both saw the helplessness in each other's eyes.

The next three have no problem.

In addition, the man went to call, and there was no problem after checking.

Not to mention the other two women, they are both innocent.

Oh, except for the stealing one.

Sending the last person away, Lin Jun leaned his elbows on the table and fell into deep thought.

There were no clues on the fingerprints, and the surveillance did not find them.

How did the murderer get in and out of the stairwell without realizing it?

Lin Jun was a little hard to think of.

There were many thoughts in my head, but none of them were useful.

"By the way, Lin Xisheng has a problem, how did you find out?"

Lin Jun had no choice but to change his mind and ask Xiang Ma Jundao.

"It was reported. "

"Said that he found that Lin Xisheng had a problem. "

So we started looking at him. "

Ma Jun soon returned to Lin Jundao.

"Is it an anonymous report?"

Lin Jun hurriedly asked.

"No, it's a real-name report. "

Ma Jun said.

"Where is that man now, take me to meet him. "

Lin Jun immediately commanded.

"He is also a clerk of this bank, and he is also Lin Xisheng's subordinate!"
