Aunt Liu and the security guard looked at each other and shook their heads.

"We are the old community, so there is only one security guard at night, I can only control the entrance and exit of the door vehicle, the yard is 11:30-12:00, I will turn around each unit to see if the unit door is locked."

I didn’t hear anything!

Oh yeah!

Just now, your people went to the guard room to get surveillance!

But this monitoring looked at the white, on both sides of the community side of the courtyard wall planted with purple radial, one day dark at night, everything is blocked, not to mention the entry of a person ten people can not see."

Chu Mengyan looked at the security guard, "Why did not you react early if there was such a problem?"

Aunt Liu patted Chu Menghan's arm.

"Girl, this is not to their security, these violets were planted when the school was built, more than a certain number of years, the garden bureau does not let move."

"Let's go and see the place."

Zhou Hai already knew enough information, and the crazy two put on the survey clothes and carried the box to the lawn.

The boy was lying on his back on the ground, already without breath, covered in blood.

This blood is not caused by a fall injury.

But from the neck, the child's left neck, from the bottom up was cut a knife, this knife is extremely deep, has exposed the cervical spine, but some skin meat is still connected.

He took a deep breath, and the crazy hands were trembling.

“Oh my God!

The children are not let go, how much revenge this is!”

Feeling sad, crazy people quickly take pictures fixed.

Glancing at the grim Zhouhai, he knew that Zhou Hai would not be lighter than his feelings, and all they could do was find the real murderer, which was the consolation to the dead.

Zhou Hai reached out and touched the somewhat deformed skull, the bone rubbing sound (1) was obvious, there was no subcutaneous hematoma, and the typical postmortem injury.

Obviously, this is caused by falling from the upper floor, but even if the child falls from the upper floor after death.

The sound of his falling ground was not very small.

Unless it is early in the morning, the surrounding people are sleeping during the period of sleep, and occasionally the sound of sex will not attract attention.

Around the boy's body, the fat man did not mark the effective footprint, after all, this is not the first scene, Zhou Hai got up and carried the box upstairs.

The madman called the staff behind him and bagged the body.

Looking at a row of carcass, the eyelids of the madman kept beating, and the first time to deal with such a case of extermination, it seemed that Liu Da thought very thoughtfully.

The madman quickly chased after the sea last week, and saw that he was standing in the hallway on the third floor, and he was standing behind Zhou Hai.

Following the eyes of Zhou Hai, I saw several blood footprints on the ground.

However, this blood footprint is not the pattern of the sole of the shoe, but the same as the footprints stepped out of the shoe cover they wear, it is all flat and flowerless.

Moreover, after walking from the third floor to the platform position, the non-fettered blood footprint is gone, and there is a blood glove stamp on the window sill, which is extremely dazzling on the white wall.

“The killer’s anti-reconnaissance ability is very strong, and it is understandable that he is wearing a shoe cover.”

He said that the fat man came out of the room and put the survey box in front of the door of the west door on the third floor.

“The door is open!”

Zhou Hai nodded, stepped upstairs, the door lock has no traces of prying.

Entering the door is a porch.

On the side of the shoe closet, curled up with the body of a young woman, head down slightly against the wall, wearing a red sleeping skirt, an arc of splotting blood on the east wall and a large number of splashing blood drops, extremely conspicuous.

However, the posture of the deceased is very strange, and when the person is injured, he will not take the initiative to adjust his physical direction.

Unless the murderer covers the mouth of the deceased, cuts the woman's neck, and slowly puts the dead to the ground to lean on one side, then what is the purpose of doing so?

Don’t want to scare others?

A pajamas, attacked at the door, that is to say, the murderer knocked on the door to enter?

Or an acquaintance?

Zhou Hai stepped forward, the woman's neck from left to right cut, and the boy downstairs, the action without a hint of hesitation, a knife to death, acquaintances can hurt the killer, do not hesitate, indicating that the grievance is very deep.

The porch ground, centered on women, has formed a huge pool of blood.

Zhou Hai stepped on the survey mat and entered the living room.

The sight in front of me is cold in your heart.

The heavy blood gas made people sick, Zhou Hai tugged the mask, made room for himself, and took two breaths.

As a forensic doctor, seeing one or two corpses is actually an extra long, but the four bodies in front of you, falling on the ground or on the sofa, the visual impact of the human being is expanded by infinite superposition.

The floor tiles, the walls, the sofas, the glass, the doors, the blood everywhere, it was a massacre.

On the sofa single seat, is an elderly man.

Now it is still the action of the head, like the red woman at the door, all the neck cuts, the sofa and the coffee table are all sputtering drops of blood, and the redwood sofa under it and the ground are also covered with a pool of blood.

The three lay an old lady in the position, or cut the neck.

However, this time the deceased was lying on the sofa, so only some blood drops were splashed on his back, and there were two bloodbaskets below the face and on the ground, but most of the blood was immersed in red satin mats, and the blood on the ground was very small.

The back of the sofa, that is, the porch straight past position, lying on a woman, her head in the direction of the stairs, seems to want to go upstairs, but the back of the heart was stabbed, and killed.

The position of the stab is extremely accurate, but the stab wound will expose the shape of the murder weapon, Zhou Hai hastened past, found the round head probe, inserted the wound, the depth has completely exceeded the length of the probe.

Moreover, the passage into the punctured turned out to be an curvature to the left.

Zhou Hai slightly, this blade is curved, and when the knife is pumped, there is a spin-lifting action, the damage in the dead body is far less than the size of the wound on the surface, this action is too professional.

After surveying the center, Zhou Hai walked toward the intersection of stairs and kitchen doors, where a young man lay on the ground.

As soon as the madman saw this man, the box in his hand was almost thrown away.

"This is too bad!

This

That's just chopping!"

The fat man groaned behind.

"The first time I saw it was half-death!"

I think the murderer hates him the most!

“After all, the worst of all!”

Yes, the man seemed to resist, but he was not at all the opponent of the murderer, the resistance of his hands was obvious, and the upper limbs of the neck were all cut and cut.

The abdomen, chest, and stabbings everywhere, the most serious is the face, the whole face is almost cut off, leaving only a layer of skin and head connected.

On the glass door behind him, all are flowing blood, and the area is very large.

There was some clue in Zhou Hai's heart, stepping on the floor of the mat.

He wanted to see where the child had fallen, where the third floor had no window open and no support at the window, and as a three-year-old child could not climb it on his own, so he could only be on the fourth floor.

Stepping on the floor.

All the way to the shocking blood footprints, but also constantly marching upstairs, and even a long strip of wiping blood on the wall.

Zhou Hai almost ran upstairs, and a door was wide open to the entrance of the stairs, and there was a thorny blood footprint on the bed.

The windowsills, the glass, the walls, the curtains, and the white sheets were all splashed down.

The invisible window of the window had been broken, and it was thought that the boy had been cut and turned back, and the window could not bear the weight to be torn directly.

Seeing that the gap in the screen window was constantly being blown by the wind, everyone's heart seemed to be torn to pieces.

1) Injection-like blood is blood stains formed by the movement of blood down along the surface of the object under the influence of gravity.

Under experimental conditions, in the tilted and smooth carrier such as glass, the typical lepage of blood is a column or cylindrical shape, generally has the characteristics of thick and thin width, and the color is light and thick;

Its length and thickness are proportional to the blood volume, the slope and smoothness of the carrier, and the absorption performance of the carrier is inversely proportional.

However, in actual cases, due to a variety of factors affecting the human body, carrier and related objects in the environment, such as the above form is very typical of the injection blood is rarely seen.
