At 10 o'clock in the evening, the newly built office building of the Huacheng District Public Security Bureau was magnificent and solemn.

The police badge on the roof of the building shines brightly in the light, driving away the darkness of the night.

Next to this office building is a lower office building, which is the case center of the sub-bureau and the office building of the criminal investigation brigade.

In the conference room on the fourth floor, seven or eight people sat around the conference table, starry and smoky.

That's right, this is the scene of Mu Yuan's dream when the police scratch their scalp and delve into the case.

Qinglong Street replied, but no one was found. I'll be looking for it again tomorrow, but there's not much hope. Captain Liu's face was bitter, and his half-bald head seemed to have a few less hairs.

A young policeman under 30 years old played with a pen with one hand, looked at the map of Huacheng District hanging on the wall, and said with a little suspicion: "Could it be that they missed something? After all, they are not specialized in criminal investigation and are not professional." ”

"Wang Ziyu, don't affect unity!" Deputy Director Li, who was sitting at the head of the front, glared at him.

The young man's neck stretched, then retracted.

Captain Liu said to himself: "Several cases were committed at the Qinglong Street Police Station, and the monitoring showed that this person's activity area was also around Qinglong Street, and from the characteristics of the crime, this person was very familiar with the jurisdiction of Qinglong Street, and the location chosen for each crime was very hidden, and it was all blind spots for pedestrians. If this person is not from the jurisdiction of Qinglong Street, it is not very reasonable. ”

"But more than 100 people in Qinglong Street have been carpet-like for most of the day, running through almost every community and every residential building, and have not found any suspicious targets. Can this person still drill into the dirt?"

"Could it be that we're going in the wrong direction?"

"What if the owner of the back we listed as a suspect isn't the suspect?"

Everyone fell silent, if it was really in the wrong direction, then everything they had done before was useless.

Although it is true that criminal investigators often do useless work, this time everyone does not want this. The previous four crimes were only two days apart. Counting the time, this bastard will be active again today and tomorrow.

For a while, the smell of smoke in the conference room became stronger.

Wang Ziyu suddenly said, "Why don't we find an expert in criminal portraits." ”

"We've done computer simulations before, and the results are not ideal. Captain Liu said, "The main reason is that the victims are all children, and the time when the suspect chooses to commit the crime is early in the morning or evening, and the light is not very good, so it is impossible to obtain an effective simulation portrait." ”

Wang Ziyu originally wanted to refute the computer simulation portrait, but after listening to the latter sentence, he shut up directly.

Even the most awesome experts have to be caught if the victim can't describe the physical characteristics of the suspect.

Captain Liu suddenly pressed the cigarette butt in his hand into the ashtray.

"Everybody will work overtime tonight. Feng Long, your group will monitor the surrounding area of the crime site again tonight, and don't let go of any details. ”

"The rest of the people, half of them stayed in the team, and I kept an eye on the surveillance, and all the important intersections near Qinglong Street had to be under control. The rest of the people, all go to the squatting. ”

"Lao Wang, you will contact the victim's guardian again tomorrow morning, and try to learn more about the characteristics of some suspects. ”

"As a serial indecent case, there were no biological samples left at the scene, and the smell environment was also destroyed, which shows that this bastard has a strong sense of anti-reconnaissance. We must be prepared for a protracted battle. ...... Is there anything else you would like to emphasize?"

Deputy Director Li looked around, felt the heaviness of the atmosphere in the conference room, and groaned slightly: "For this case, everyone must have enough sensitivity, be loose on the outside and tight on the inside, and solve the case as soon as possible." The city bureau also gave clear instructions, two third-class merit places, one individual and one collective. I hope that everyone will work hard to bring the suspects to justice as soon as possible......"

A few short sentences, but it mobilized everyone's enthusiasm.

In a provincial capital city like Xihua City, you must be eligible for a serious and extraordinarily serious case, and now in an indecent case, two third-class meritorious service places are promised, and this intensity can be described as unprecedented.

However, this also illustrates the fact that this case has also made the city feel the pressure, and it has to take some measures to mobilize the enthusiasm of the case-handling personnel below.

......

The bus shook slowly, and Mu Yuan closed his eyes and looked like he was about to fall asleep.

This is the No. 98 bus, which is a very unpopular line, and you can find a place to sit on the bus at any time.

Soon, the bus stopped in front of a station, and Mu Yuan got off the bus through the back door with one hand in his coat pocket.

After getting off the train, he did not leave immediately, but walked around the platform.

After a few minutes, a hint of disappointment flashed in Mu Yuan's eyes.

"The seventh stop, wasting 14 yuan, and I don't know if I can repay the account. ”

When another No. 98 bus came over, Mu Yuan got on the bus again.

The bus at about 10 o'clock in the evening, like a little donkey with enough forage, ran happily.

But in seven or eight minutes, the bus on-board radio sounded: Linxia Road has arrived, please get off the bus passengers from the back door, please pay attention to safety when getting off. Lixia Road arrived，the passengers get ......

Mu Yuan got up again, and Shi Shiran got off the bus.

The moment he got out of the car, Mu Yuan's eyes lit up.

"That's right!

He smelled the familiar smell of sweat on his feet again, and his eyes were a little spicy.

A few hours ago in Qinghua Lane, Mu Yuan smelled the smell of sweat on the road and disappeared on the road, and concluded that this person should have left by car, and by taxi.

Mu Yuan couldn't determine the exact time of the other party's departure through his breath, even if it was just an hour, there were thousands of cars passing on this road, which had no screening value at all.

Besides, for the possibility of the suspect leaving by car, the police handling the case of the special case team can definitely take it into account, and have carried out a corresponding investigation, since no clues have been found, there is no point in pursuing it in this direction.

Just when Mu Yuan was about to give up, he suddenly reacted, since this guy's way to escape from the crime scene was impassable, it was better to follow the route he took to enter the crime scene.

Subsequently, Mu Yuan spent more than half an hour, relying on his sense of smell, which was stronger than a dog and comparable to that of an African elephant, to find the location where the other party entered the scene.

Bus stops.

It's not a standard bus stop, just a vertical line sign, and there's only one bus on it, which is the 98.

Although it is also possible that the suspect got off here in a taxi, judging from the situation at the scene, it is more likely to take a bus, even if there is only a glimmer of hope, Mu Yuan decided to track it down.

This chase chased eight stations, and Mu Yuan almost gave up.

Now, there is one more fool on the sidewalk on the south side of Linxia Road, walking a distance, and then turning aimlessly......

This is also a helpless thing, after all, it has been two days, and the smell has escaped seriously.

Mu Yuan muttered: You can't see me!

Walking along Lin Xia Road for more than two hundred meters, Mu Yuan's eyes suddenly lit up, and the smell of spicy eyes suddenly became strong.

Judging by the strength of the breath, this person should have been active here for the last hour.

If nothing else, this guy's lair should be nearby.

"It's so simple?" Mu Yuan was confused, "The guy from the task force is so good?"

Mu Yuan decided to ignore these details for now, and it was serious to catch talents.

Now that the aura here is so strong, it is too easy for Mu Yuan to track.

Searching along a route with the strongest smell, Mu Yuan was also constantly looking at the surrounding environment.

The environment can affect a person's psychology, and a person's psychology can also determine what kind of environment he chooses, whether it is life or crime......

“...... Noble Community...... Elegant ......"

"Bright-looking, good at camouflage, well-educated...... Dark inside......"

Slowly, a vague image gradually became three-dimensional in Mu Yuan's mind.

At this moment, Mu Yuan's mind was a little confused, the ghost knew what his brain had experienced, how could he analyze this?

Suddenly, Mu Yuan had a flash of inspiration, and thought of the criminal mind portrait technique he had just obtained, which seemed to be ...... This technique is not so frivolous.

If you can know more about the details of the crime, you may be able to find out the suspect's behavior and habits with a high probability, and even in this kind of serial case, there is a certain chance to guess the time and place of his next crime.

After more than ten minutes, Mu Yuan stopped and looked ahead.

Under the street lamp more than 30 meters away, a middle-aged man of nearly forty years old stood.

Nearly 1.8 meters tall, with a thin body, and a backpack on his back - this kind of outfit is very common, and usually people who are engaged in product sales will carry such a bag.

The light came from top to bottom, illuminating the man's face with sharp angles.

Mu Yuan pretended to walk over casually, and when he had not yet reached ten meters after crossing the man, the smell stopped.

The situation is already clear, if nothing else, this person should be the person he is looking for.

Whether he is a suspect or not is uncertain.

Although the Criminal Investigation Brigade Liu said before that the suspect was tall and burly, which was very different from the person in front of him, Mu Yuan didn't take it seriously.

Could it be that the conclusion of the Criminal Investigation Brigade is correct?

Habits of crime?

Hehe......

For a criminal with a strong sense of anti-reconnaissance, the habit left by the police may be a hole dug.
