After Xiao Mo finished speaking, he glanced at the sea of clouds that had been silent.

"Yunhai, your thinking has always been special, you can talk about it."

Yun Haidao: "Actually, you have analyzed a lot of traffic here, and I think it is not a question of whether it is hard or not, but a question of the direction of thinking."

From the very beginning, the direction of the analysis was wrong, and the key point of the issue in Zhu Dahai's case was who belonged to the other set of shoe prints at the scene.

Don't tell me about the question of whether it is a coincidence, where in the world are there so many coincidences, Zhu Dahai just fell from the building that night, and that footprint did not appear for a long time, but it appeared when someone died.

In my opinion, it's actually quite simple.

I bet the suspect was there all the time when you arrived at the scene and were surveying the scene. ”

As soon as Yun Hai said this, everyone present suddenly looked surprised and waited for his next words.

Yun Hai cleared his throat and continued.

"First, I agree with Xiao Mo's statement that the owner of this set of shoe prints may be a woman. It's just possible, after all, the height is 165, and there are still a lot of people who wear size 43 shoes.

Second, from the report given by the trace department, the biggest difference between this set of footprints and Zhu Dahai's footprints is that there is basically no mud in the shoe prints. It rained so heavily that night, and the construction site was extremely muddy, which was also the reason why there was mud on Zhu Dahai's shoe prints.

In addition, the stairwell from the first floor to the fifteenth floor did not find the existence of this set of size 43 shoe prints. This man did not come up from the stairwell. He is not an immortal, so naturally it is impossible for him to fly up.

There are only two ways to get to the fifteenth floor, the elevator and the staircase.

There was a power outage that night, and the only elevator on the site was naturally unusable because of the power outage. This is also the reason why Zhu Dahai climbed the stairs.

The other set of shoe prints, instead of climbing the stairs, can only take the elevator.

And the elevator can only run before the power outage, and this shoe print is so refreshing, this person should have taken the elevator into the building before it rained.

The rain on the day of the crime began to fall in the afternoon, that is, the person had been on the fifteenth floor before the afternoon.

Thirdly, this person can stay in the building from day to night, regardless of the wind and rain on the day of the typhoon.

Naturally, it is not homeless, but there is something else, and it should have been planned for Zhu Dahai's life a long time ago.

Psychological profiling experts have studied that when many criminals commit crimes, they have already planned everything in their hearts. They will commit crimes according to the rules they have set.

So the suspect is all ready, just waiting for Zhu Dahai to take the bait.

At this time, Chen Yang's mobile phone came in handy.

Chen Yang's WeChat sent out this picture played a key role.

This person knows Zhu Dahai very well, knows that this person treats his work very strictly, and must know that when Zhu Dahai receives this picture, he will definitely come to the construction site to take a look.

When Zhu Dahai arrived, this person must have done something on the fifteenth floor, such as lighting or something, to attract Zhu Dahai upstairs.

Zhu Dahai is tall and strong, but this short man can easily succeed, which shows that this person is very familiar with Zhu Dahai, and Zhu Dahai will relax his vigilance.

In addition, this pair of size 43 rain boots is actually used to confuse people, only when it rains, they wear rain boots, which makes people mistakenly think that the person is on the fifteenth floor after the rain.

I deduced that the man had put the size 43 rain boots in a bag, took the elevator to the fifteenth floor, and changed into the pair of rain boots.

When Zhu Dahai fell from the fifteenth floor, this person stayed on the fifteenth floor, waited until the next day's call, and then took the exterior wall elevator down to the first floor.

Then he took off his rain boots and threw them into the greenery.

But most offenders lose control when it comes to making rules, and as they become more and more proud of their masterpiece, loopholes appear that leave evidence for the police.

Yesterday I went to the site and made two discoveries.

First, in a utility room in a simple board house, I found a lot of similar rain boots.

I asked the on-site office staff, and the rain boots here belong to the on-site office managers.

In addition to the workers on the construction site, there are also managers who work on site.

I initially pinned the suspect among the managers working in these scenes.

Second, many murderers like to hide in the crowd and watch the development of events, which is a special psychological effect.

On the one hand, I want to observe the police's investigation thinking and whether the development of the situation is unfavorable to me.

On the other hand, there are purely psychological needs.

I suspect that the suspect had been watching developments at the scene before and after the police arrived, for the simple reason that he had been watching.

The security guard Wang said that when the call came on the construction site, 120 ambulances came.

In other words, when the 120 ambulance came, the suspect should still be on the fifteenth floor.

When the suspect had the opportunity to take the elevator down from the fifteenth floor, it was also at this time, before the 120 ambulance left, the police came to the scene.

At that time, the scene was chaotic, and no one would have noticed that the elevator on the north side had come down from the downstairs.

If this person wants not to arouse the suspicion of the police, he will definitely try to cooperate with the police investigation. It is even possible to behave a little more positively.

Psychologists have studied that many perpetrators of murder will return to the crime scene after committing the crime.

This kind of person has a mentality that the most dangerous place is actually the safest place.

It is also a provocation to the police.

There have been cases in China where after a homicide, the suspect even carried the victim's body to pass by the police calmly, and then dumped the body elsewhere.

Therefore, I think the next direction of reconnaissance should be those managers on the construction site, or those who have a close relationship with the managers.

The range is small, and the target should be determined very quickly.

As for Zhu Xuan and Liu Duoduo, the objects of Xiao Mo's suspicion, I don't think it's very likely.

First of all, although Liu Duoduo and Zhu Xuan have a close relationship, Zhu Dahai once saved his mother's life after all.

Secondly, no matter how unbearable Zhu Dahai's father is in Zhu Xuan's eyes, there is a saying that if you break bones and connect tendons, the family is a family after all.

There are many women in the world, and he Zhu Dahai is not short of money, so naturally there are many women leaning forward.

And Zhu Xuan is young and handsome, has a good job, and has a good family background, does he lack women?

The father and son can turn their faces for a woman, but it definitely not to the point of death.

I think the suspect is someone else, and this person has a fatal affair with Zhu Dahai.

This festival is due to two reasons, love and hatred.

As for the cause of Chen Yang and Huang Feifei's car accident, I think it is definitely not a coincidence, perhaps it was committed by the same person as the suspect in Zhu Dahai's case.

is still the same sentence, there is love to hate, and there is affection to hate. This is a serious interpretation of the meaning of the word love and hate. ”

Yunhai's last sentence was philosophical and well analyzed, and the participants agreed. The bureau spoke, the case was urgent, and the investigation was launched according to Yunhai's ideas.
