Cold.

Entering the water directly without exercising made Lin Yuhan's pores suddenly shrink.

He shuddered, feeling a large amount of cold air pouring into his internal organs, stimulating the meridians all over his body.

He tensed his muscles and nerves and struggled through the water.

Fortunately, the students who graduated from the police academy are in good physical condition, otherwise they would be in danger of cramping if they suddenly enter the water.

He felt a little impulsive, it was so late, he should have warmed up before entering the water.

Slowly, he adapted to the rhythm of the water, his body was no longer stiff, and he swam towards the opposite shore.

It's a gut feeling.

If it was the water demon in the water that killed Li Yue, he had to put himself in his shoes and experience the inner feelings of the "water demon".

As if he were a criminal, he swam to the center of the lake with trepidation after killing someone.

At this time, his movements are awkward, because he is holding the "woman's head" in his right hand, and his body is unbalanced, but he has a good water nature, and he can cope with the coming and going in the lake freely.

It's a very risky move, and no one knows if there is an undercurrent in the middle of the lake that can suck in instantly.

This is too dangerous, and Lin Yuhan's body is still very difficult.

However, he still relied on strong faith and swam forward.

Finally, he swam to a position close to the center of the lake.

It should be safe here, and then he "let go", and the human head sank into the water.

The lake returned to calm, and he watched the human head sink deeper and deeper in the water, and his heart felt more satisfaction and peace of mind than ever.

It's so far from the shore that no one will find out where the head is. The lake had washed away most of the blood and marks on his body, and no one could detect anything out of the ordinary.

When he looked back, the shore was too far away from him, and if he went out from there, there was a possibility that he would be photographed by the surveillance, and his physical strength was gradually decreasing, so it was better to ...... He looked at the opposite shore of the lake and continued to swim ahead.

Finally, he had exhausted almost all his strength and reached the opposite side of the lake.

A path came into view, and it couldn't be safer.

Sneaking away from here, no one will find out, and no one will think, he crossed the entire surface of the lake and fled from the scene of the crime.

He shook off the drops of water on his body, and with a wicked smile on his face that had succeeded in his conspiracy, he left the park with confident and calm steps.

Lin Yuhan felt that his legs were filled with lead and he was exhausted.

He sat on the shore panting, waiting for the evening breeze to dry the water on his body, then turned on his flashlight and searched carefully along the opposite shore.

He didn't go far before he found a surprise.

This is...... Footprints!

Lin Yuhan hurriedly leaned down and carefully observed a few traces of these deep depressions.

The shoe print extends outward from the direction of the shore.

I see, Lin Yuhan has figured everything out!

During swimming, your shoes are covered with lake water, and the mud on the shore is very soft, so it is easier to get stuck in the mud and leave footprints.

This is a trace that the murderer cannot erase.

This path is a relatively remote section of the park, and there are very few tourists passing through here, and more importantly, there are only those who go out and do not go in, which shows that

The murderer who disappeared swam from the other side!

The shape of the footprint also fits well with the grass opposite.

The killer probably didn't care much about these footprints, as few people thought that he would flee the crime scene in such a way.

The mystery has been solved, and I have to say that this step is really clever.

First, hide your whereabouts and not be easily discovered by the police.

Second, discard the victim's head. Although there is no surveillance inside the park, the main road on the periphery is densely monitored, and if you go out with suspicious items, you will soon be targeted by the police.

Thirdly, clean up the blood stains on the body, and after soaking in the lake, the traces of the victim are gone.

Then, he left the scene generously, and even if he was discovered, he couldn't see anything abnormal.

Even if the incident happened afterwards, he could make up reasonable reasons to explain.

What a move, killing three birds with one stone!

Although this trick is very dangerous, and the slightest mistake will sink you in the lake, if it is successful, it will turn the crime scene into a perfect murder. Murder almost without a trace.

Lin Yuhan quickly drew the profile of the murderer in his heart.

Footprint shoe size 43~44, according to the depth and size, the murderer should be between 180 and 183 in height, good physical fitness, and sufficient physical strength, otherwise such a long distance, I am afraid that the middle way will collapse halfway through.

The murderer must be very familiar with Li Yue, otherwise it would be impossible to meet in the park so late.

The idea gradually became clear, Lin Yuhan felt that he was getting closer and closer to the truth, and the murderer was about to come out.

As long as he cooperates with the surrounding surveillance, and a little bit of evidence, he can bring this demon to justice.

In addition to the excitement, Lin Yuhan realized a serious problem.

How do I get back?

The physical strength has been exhausted, and it is impossible to swim back from the lake. If you follow the shore, you have to walk three or four times the distance.

Moreover, his clothes are still on the opposite side.

Despair, wandering naked in the park, fascinated and embarrassed.

Lin Yuhan sat on the big stone by the lake and rested for a long time, sighed heavily, let's walk along the shore, if the mobile phone is by his side at this time, he can shake people.

Who made him overestimate his physical strength just now.

After walking for an hour, Lin Yuhan finally returned to the opposite place of the water with great fatigue.

He put on his clothes and couldn't wait to take out his mobile phone and call Wu Hao.

There was only one sound, and it was picked up by Wu Hao.

This brother is still working overtime? It's quite hard!

"What's wrong, Detective Lin?" Wu Hao's tone was even hungrier than Lin Yuhan.

"Help me check the surveillance video of the entrance and exit of Nanhu Park on the day of the crime, and then send it to me." Lin Yuhan replied.

"Brother, I've already checked it~" Wu Hao's voice was slightly tired, obviously he didn't have a good time this night, "At that time, the only suspicious vehicles entering and exiting were Chen Yousheng's." The other two cars are couples, looking for a place where no one is in the park at night, what to do can be imagined, we have already checked their backgrounds, and they have nothing to do with the case. ”

"You're talking about the entrance to the West Gate!" Lin Yuhan corrected, "I want to see the east gate." ”

"East Gate?" Wu Hao was puzzled, "Which East Gate?" ”

"There are also a few east gates in Nanhu Park! The scene of the crime is across the path directly opposite the South Lake, and walks past the east gate that connects to it. ”

"Wait a minute!"

Wu Hao tucked the phone over his shoulder, and as he spoke, he pulled over the map that analyzed the case and drew it with a pencil.
