What does it taste like?

Wu Jie frowned slightly.

Seeing this, the criminal investigation expert immediately explained:

"This bush is not far from the road, and it is relatively easy to block the view, so it must be convenient for people to come here from time to time!"

Wu Jie frowned and said: "There are not many people who know this road, and there are definitely even fewer people who know that it is convenient to come here!"

"Locals committed crimes!" the forensic expert immediately reasoned.

"Let's go up the highway and have a look!"

Wu Jie immediately went downhill and came to the highway in three or two steps.

This abandoned pothole-ridden concrete road is in disrepair and is already a little muddy.

In some places, it's no different from a dirt road.

Therefore, you can basically see footprints and wheel marks.

In the fresh wheel imprints, according to the width, texture, etc., it can be seen that there are road tires, off-road tires, and bicycle tires.

Bicycle tires?

Nima!

This road is so bad, the off-road vehicle is too bumpy to come in, who will ride in without anything?

Follow the mark to the bush directly facing the road, and sure enough, there is a bicycle tire mark.

Closer inspection revealed that all three locations were imprinted, and there was a noticeable pause.

Tricycles are light and adults are heavy.

If the suspect is a local, ride a tricycle and take a slow and leisurely shortcut and pass by here.

Just urgency, then he naturally braked to stop, and then went to the bushes on the side of the road to make it convenient.

Get up, sit down!

The tires are compressed differently, and the wheel marks formed naturally have a certain shade of variation.

And the reason why they noticed this was only because Wu Jie and the criminal investigation experts, under the watchful eyes of many onlookers, were almost lying on the muddy road, making precise measurements.

In order to find Yuan Zihan, Wu Jie really worked hard.

Many onlookers had already recognized his identity and were talking outside the cordon.

"Oh my God, isn't he the civilian model who counterattacked the beautiful president? Why is he here to help investigate the case?"

"The couple set up a charitable foundation dedicated to caring for children, and if an orphan is missing, he will definitely come!"

"With a net worth of hundreds of millions but still willing to lie on his stomach in the mud, it's really not something ordinary people can do!"

"What kind of goddamn bastard would kidnap such a beautiful little girl!"

"Usually not many people walk on this road! The road is so bad, driving away is purely to find guilt!"

"Has anyone passed by on a bicycle in the evening?"

......

When everyone was talking, there was new progress in the on-site investigation.

From wheel imprints, to brake imprints.

It can be basically determined that the suspect's vehicle was a human-powered tricycle.

As soon as the brakes are tightened, the pulleys will 'lock' up.

So the tires will be clamped for a split second and then the translational friction will stop on the ground.

Since the lockdown is a tricycle, the scope of the investigation has been rapidly reduced.

The speed of the tricycle is not fast, and it relies on human pedaling and riding, and the probability of leaving Tianyuan is very small.

And there are all kinds of signs at the scene that this is a 'sudden' crime.

The suspect did not have any premeditation or any warning, and suddenly committed the crime.

It's like......

Walking on a deserted road, I suddenly saw 100,000 pieces on the ground.

Pick it up and keep it for yourself, it's a sudden crime.

Since the hole in the courtyard wall of the orphanage was formed by accident, it was also accidental that Yuan Zihan ran outside the courtyard to hide and seek.

Then, the suspect must have taken him away by chance.

Based on this, everyone deduces that this person should not be a human trafficker.

In this year, when electric vehicles are very popular, I also ride a rickshaw......

Then the economic income and social status should not be high.

As a result, the scope of the investigation was rapidly narrowed down.

Within three kilometers, all surveillance cameras immediately traced back to find the tricycle.

The police officers at the scene immediately began to ask if anyone had seen a tricycle rider pass by this road in the evening.

You can know this abandoned road, and you can know the bushes...... It's certainly not the first time I've passed here.

This inquiry, there is really a clue.

"Isn't there a scrap yard over there, where there are a lot of scavengers and cleaners, and they all ride tricycles!"

A voice shouted.

As soon as these words came out, they instantly ignited the emotions of all the case-handling personnel.

The command immediately ordered the special agents who were investigating the surrounding area to quickly surround the freight yard.

Alarm howling!

Police cars, riot vehicles, and special vehicles rushed around the bad roads at lightning speed, and under the leadership of the local people, they pounced on the old freight yard where the suspects might be hiding.

Wu Jie rode a wheeled armored car, roared and galloped, jumped over the bumpy muddy road, and soon arrived at the old freight yard.

The old yard is less than four kilometers away from the orphanage in a straight line, and it is surrounded by old neighborhoods.

The surrounding land acquisition and demolition have basically been completed, but the construction has not yet started, so it is like a no-man's land.

How can there be Skynet monitoring in a dark place like this after dark?

The old freight yard is next to a deserted railway, and you can smell the stench from a long distance.

There's a scrap yard with plenty of cardboard, drink bottles, plastic bags, and more.

Waste products are piled up in mountains and emit foul odors.

The riot car quickly released a high-definition drone.

Aerial footage is transmitted back in real time, including high-definition visible light and infrared thermal imaging.

The old yard covers a large area, but what is surprising is that within this high wall, there are simple slum-like houses.

Some use bamboo poles as support and cover them with awning cloths.

There are also simple sheds that are made from the boards that must be used to pour concrete on construction sites.

But most of them are made of various tarpaulins, wooden poles, bamboo poles, etc., pieced together to make tents.

At this point in time, thousands of families have already gone to bed.

But for those who have been busy all day outside, picking up waste and sweeping the streets, most of them are still cooking and eating.

Simple coal stove, stir-fry for cooking.

The drone flew silently through the air.

For these shantytowns, who have no reinforced concrete and no metal shelves, infrared thermal imaging is simply an unobstructed view of them.

As long as humans and animals are alive, they will emit heat and form infrared radiation due to their metabolism.

So in the picture, you can clearly see how many people are in each shanty and what they are doing.

Some people are stir-frying and cooking, some are already lying down to sleep, some are smoking, and some are still bundling up the scraps they have picked up......

The old yard was too big.

There are too many waste pickers and cleaners gathered.

Most of them come from rural areas, they are older, have no employment skills, and are reluctant to spend money on rent, preferring to endure the stench and sewage flowing, and also gather here.

The tall courtyard wall obscured a car.

In order to prevent the criminals from acting aggressively, the alarm was stopped long ago and the police lights were turned off.

The command has the drone conduct a close reconnaissance to select suspicious objects and exact locations.

After all, children's height and body shape are obviously different from adults, and the infrared radiation characteristics also look more petite.

Although the large warehouse is large, there are not many children inside, after all, it is not yet summer vacation.

On the other side, of course, there is a search and rescue group, an assault group, a sniper group, a negotiation team, and a medical team.

Various preparations have been made for hostage kidnapping negotiations, forcible surprise rescues, infiltration and rescue, and so on.

In order to find out what was going on inside, the investigation team borrowed an electric car and an electric tricycle.

I got some cardboard, drink bottles, etc., and pretended to go to the acquisition station to sell them, and took the opportunity to infiltrate them.

Because Yuan Zihan likes Wu Jie, the big brother, and he has a certain amount of kung fu.

Therefore, the command authorized and agreed to let Wu Jie follow a search and rescue team, climb over the courtyard wall, and infiltrate it.

There are all kinds of stenches wafting in front of you, and you are stepping on the old and broken concrete floor.

The search and rescue team, loaded with guns and ammunition, slowly moved forward.

Passing through one shanty after another, many people were shocked to stop and watch.

Of course, they didn't know what was going on, but they didn't dare to keep up.

After a closer look, the drone identified three suspicious shanty houses, all of which had the infrared radiation characteristics of children.

The various groups quickly followed up and quietly surrounded them.

Next to a pile of cardboard boxes, Wu Jie's search and rescue team stopped.

There was a suspicious shanty right next to it.

The shanty is made of sticks and planks and is lit with candles.

The light of the candles peeked through the gaps, and the doors made of two plywood panels were very large.

With the help of the light that came through, you could see a tricycle parked next to the doorway.

The tricycle was shabby and the wheels and fenders were fresh sludge.

And inside the shanty, there is a deep man's voice.

"That's good! Grandpa likes obedient children who don't cry or make trouble!"

"Grandpa is not a bad person, grandpa just misses my daughter, can you stay with grandpa for a day?"

"Grandpa will send you back tomorrow, you must talk and count!"
