Fang Lei stood in the shadows, watching from a distance the residents of the community who were walking their dogs on the lawn.

It was half past six in the evening, and the sky was still clear, but the heat seemed to be less during the day.

The weather forecast says there will be short-term heavy rainfall tonight.

From the end of June to the present, this year's rainy season seems to be different from previous years, the rain has only been intermittent, and the prolonged high temperature has been a bit abnormal, and tonight's rainstorm may draw an end to this, dragging the summer into a dog day completely.

Fang Lei swallowed his saliva hard, and his mind was a little disturbed by the feeling of oppression brought by a low air pressure.

It could also have been caused by the discovery at the forensic center during the day.

In order to further confirm their judgment, forensic doctor Lao Yang removed some hair from the dog's corpse and then compared it with the dog hair collected from the toenails of the deceased Gu Xinyue, and the results showed that the similarity reached 99.87%.

There is no doubt that this dog hair belongs to the big yellow dog that fell from the sky.

This conclusion further illustrates two possibilities: first, given that the deceased was wearing a pair of open-toed sandals when he was found, it can be inferred that the deceased had visited the Rose Garden community before his death, came into contact with the big yellow dog and got dog hair;

Second, the murderer touched the big yellow dog, and then accidentally brought the dog hair to the deceased, so that the murderer is very likely to come from the Rose Garden community.

Either way, the Rose Garden community will be a key location for the investigation of the case.

Fang Lei took the latter's new forensic report from Lao Yang's hand, and said that he would bring it to Captain Jiang Jian when he went back, but as soon as he left the forensic center, he turned around and left the Public Security Bureau.

With the lesson of the last time, he planned not to tell Jiang Jian about this discovery for the time being-Jiang Team was right, the task force had done a lot of homework on this case, and it was not allowed to be easily questioned and denied by others.

Now it's his turn to do his homework.

When he arrived at the rose garden, he went directly to the property and told the front desk reception that he wanted to find Manager Wang.

But the front desk made several phone calls but didn't get through.

After thanking him, he walked out of the property and saw a battery car parked in front of the door.

It was the one that Manager Wang rode last time.

He looked back and found that the window in the manager's room was closed.

On such a hot day, the windows are closed so tightly, needless to say, the air conditioner must be turned on in the house.

Maybe Manager Wang has been in the house all the time, but he just doesn't want to waste time with him like he did last time.

Fang Lei didn't say anything anymore and left the property center.

To find the suspect, you must first find someone who has been in contact with and knows the dog, but the problem is that the dog is dead, and it may be a stray dog without an owner, and it can be difficult to figure out its condition.

He took out his mobile phone and found Jiang Jian's phone.

However, he hesitated again when he was ready to call.

After thinking for a moment, he put away his phone.

It's better not to contact him for the time being, Fang Lei thought, he might be interrogating that Liu Hui at this time, maybe he has already tried something, and now he is likely to get another ridicule when he calls him. He was not afraid of being ridiculed, but felt that there was no need to interrupt others to enjoy the happiness of his proudest moments.

Could Liu Hui be the murderer? It's possible, but Fang Lei doesn't think it means that it's wrong for him to investigate the dog hair.

Of course, the most likely outcome of such an investigation will be a failure.

Maybe Liu Hui has already admitted that he is the murderer, he has only been to the rose garden to deliver takeaways, passed by the place where the big yellow dog stayed, and got dog hair on his feet, and then passed it to her when he killed Gu Xinyue.

It is not excluded that there are such coincidences in the world.

But what made Fang Lei unable to let go was that in addition to the dog hair, there was another thing: Gu Xinyue's death (being smashed by a blunt object) was almost exactly the same as the dog's death.

One thing may be a coincidence, and the probability that two things are still coincidental when superimposed is relatively low.

If Liu Hui is the murderer of Gu Xinyue, then he may be a pervert who tortured and killed the big yellow dog.

Fang Lei flashed a picture in front of his eyes - Liu Hui came to the rose garden to deliver takeaways, maybe it was night, he saw the stray dog, lured it to a hidden corner with food, covered its head with a cloth bag, and used the knife he carried with him to stab and scratch it continuously, enjoying the pleasure of animal cruelty, and finally slammed its head with a claw hammer, hammered it to death, took away the cloth bag, and fled.

But what about that high-altitude dog crash?

Why did the suspect put the dead dog on the roof and throw it down to kill passers-by?

Was it an accident or a deliberate act?

In addition, there is another thing that puzzles him is that the rooftop is completely closed, how did the suspect take a big dog up and leave after throwing the dog?

The door to the rooftop hadn't been repaired since it was kicked by Fang Lei last time, so he easily went in this time. Perhaps because of the impending heavy rain, it was noticeably not as hot on the roof today as it was last time. Fang Lei turned around and quickly found a detail that he had overlooked last time.

The suspicion may lie in those thick cables.

In fact, he saw those cables last time, from the top of one building to the top of another, but he ignored them because he didn't think about the child.

Now it seems that they are like gliding ropeways, and these buildings are not usually high, for example, from the building on the right hand side to the one in the body, from the 33rd to the 31st floor, there are two more floors of nearly six meters high, and this height causes a tilt enough for the suspect to slide over the next building. The building on the left is only 28 floors, so it is also convenient for the suspect to slide over this building and escape.

He took a closer look at the cables. The diameter of this cable is about 240mm, from the inside to the outside by the conductive core, insulation, sealing sheath and protective covering, the bearing capacity is more than 50 kilograms, a big man like Fang Lei may not be able to bear it, but if the weight is about 50 kilograms, it should be achievable.

Thinking of this, Fang Lei couldn't help but be surprised, could it be that the suspects who threw the dogs were a group of children weighing thirty or forty kilograms and not more than 12 years old? All they need is a sturdy metal hanger per person, which can theoretically be done with this kind of gliding.

That's right, it can only be said that it is theoretically possible.

What Fang Lei couldn't imagine was that a group of children would have such the courage to use a hanger to slide from one building to another from a height of tens of meters. You know, if you make a slight mistake, you will be crushed.

A group of children fly around the rooftops of every building in the neighborhood like agents, coming and going freely, which is a scene that even in the movie dare not appear. But he looked around, and there really was no other possibility besides this possibility.

In any case, now the scope of detection can try to focus on those children, maybe it is a breakthrough.

Therefore, after Fang Lei went downstairs, he kept wandering around the community.

It's summer vacation, and the probability of meeting children in the community will be relatively high. Unfortunately, it was early afternoon, and I didn't meet a few children along the way.

Fang Lei left the community, bought a bottle of Suntory sugar-free oolong tea at the FamilyMart convenience store at the north entrance of the community, sat down at the bar by the window, blew the air conditioner, and waited until the afternoon before he returned to the community.

Now, standing in the shadow of the trees, he observed the dog walkers that had gathered on the lawn.
