Sea of Nods.

"The scene is too complicated to make it clear, I drew a floor plan so intuitive."

The door was pushed open again, and Director Pang walked in with Liu Da and Chu Menghan.

“The doctor has worked hard!

We’re going to a meeting on the fourth floor, let’s go together.”

Zhou Hai looked at the glass whiteboard, as if last night should have been in the conference room to write this, it is a big project to move it.

The fat man waved.

“Go to it!

Some of us took it!”

Crazy and small beam rushed to help, not to mention very heavy, fat man himself to make some effort on one side, Zhou Hai just want to move, Chu Menghan shot, reach out and hold the glass whiteboard bracket.

"I want to remind you that there is a wheel below!"

It can be pushed.”

Instantly the air in the room solidified, the fat man looked at Chu Menghan, with grudges.

Xiao Liang squatted down, carefully observed, and really pressed a button on the side of the square hole of the base, the lock of the wheel was opened, the glass whiteboard was easily pushed, and several people did not speak, pushing the glass whiteboard to the elevator.

On the fourth floor, I found that there were many people who participated in the project meeting.

Several people quickly found an empty seat, and Zhou Hai just wanted to go back and was shouted by Liu.

"Charge Zhou, tell me about the discovery of the on-site investigation and autopsy first!"

He walked over to the whiteboard and looked around.

“This is a picture of the 8.25 extinction case.

Let’s not talk about the nature of the case.

Because the case is more complicated, I will draw a road map in conjunction with the results of the autopsy, and we will look at it together.

According to the distribution of blood footprints mixed with blood, I plotted two paths, red representing the a path and green representing the b-path.

Let's look at the red A path:

There are many dense blood footprints in the porch, all around the blood pool under Zhang Junya's body, where only Zhang Junya's DNA was extracted from the blood footprints.

This footprint, moving in the direction of the stairs, but turned towards the kitchen when it was close to the stairs, and then the blood footprints contained mixed blood of Zhang Junya and Tong Xinwei.

After that, with Zhang Junya and Tong Xinwei mixed blood footprints on the building, straight to the stairs facing the second bed, in the sheet found blood footprints are mixed blood of the two.

Look at the green B path:

In the porch, only intermittent one-sided blood footprints are left, and one foot stains Zhang Junya's blood.

Subsequently, this intermittent blood footprint went directly to the living room, which was stained with the mixed blood footprints of Heping and Lu Xiangya.

The three men mixed the blood footprints, bypassed Tong Xinwei, and rushed to the position of the stairs, where there was a continuous wiping-like blood trace.

In Zhang Junming's position, it was stained with the blood of the fourth person.

The stair tower went straight to the master bedroom and stayed in all the locations with drawers.

Moreover, blood handprints were left in the bedside table and desk drawer, and only the DNA of Zhang Junming, Zhang Heping and Lu Xiangya were left.

According to the gap missing from the drawer, each of the two places is missing an item the size of a new dictionary.

Subsequently, the two paths B and A converged, and did not stop and quickly left.

The distribution of blood handprints mixed with blood at the scene, as well as the collection of mixed bloodstains on the edge of the deceased's wounds, is consistent with the narrative path.

I found out through autopsy.

The murder weapon of the deceased child Xinwei and Zhang Junming is not the same murder weapon, this is the difference between the murder weapon blade I drew.

You see, the murder weapon that killed Tong Xinwei was a half-circular knife with a blade, and the cursiveness of the blade was large, because the wound caused by each cut was only 6.5 cm, and the deepest, slightly shallow on both sides.

The murderer is very powerful, and the knife is in the bone, so the blade has a slight blade, but this blade is in the part of the blade.

And Zhang Junming's stabbing showed, a knife into the heart.

In the action of the suspension of the drawer, the lungs, liver and spleen were directly cut, forming a huge rotating cut, and at the same time, it caused scratches on the inner edge of the chest ribs.

This knife wound means that the knife is extremely long, but the blade has a certain curd, the back of the knife is straight, its blade position is on the tip of the knife, the blade of the knife is cut to the ribs when the blade is rolled.

Combined with these factors, my decision is:

The murderer is two people.

The right hand,

acquaintances are involved,

The crime was between 1:00 and 2:00 a.m. on August 25.

There is hatred for Zhang Jia and Zhang Junya,

The murderer A is more resentful of Tong Xinwei,

B. The murderer has the structure of the human body or is familiar with the relevant knowledge,

And,

Knowing the location of the family’s valuables,

The plan is detailed,

In addition to the first crime scene,

Remove the shoes and camouflage.

These two,

Height, weight, strength, shoe size, there is a big difference.

Wear gloves and shoe covers, but to confuse the judgment of the police.

It is suggested that we should start with Zhang Junya's social relations."

Zhou Hai breathed an analysis of some hair halo, but the whole meeting scene, a long applause.

It is self-evident that a family of six, clueless, can come up with such a detailed analysis in twenty-four hours, how much work has been done.

Chu Menghan raised his eyes and looked at the thin Zhou Hai with a look of examination, what kind of person is this person?

Before, he unceremoniously exposed his unauthorized actions and left himself on the side of the road.

Today, more than 20 hours of sleepless work for the case.

Who is the real him?

Liu Da got up and motioned Zhou Hai to sit next to him, holding his mobile phone at the same time, shooting the contents of the white glass next week.

"The analysis of Zhou forensics is summarized in great detail.

This path is too important to describe the murderer’s purpose.

Let's look at the two paths as two murderers!

Below,

Chu Menghan said, your work progressed yesterday."

Chu Menghan was suddenly called to the name of a little surprised, quickly holding the book to get up.

"Our side is divided into three groups, a group to investigate Zhang Junya's social relations, and found that the deceased had no less than 20 boyfriends during his work in a hospital."

I had several boyfriends before we got married.”

“At the same time?”

Chu Menghan looked at the doubtful director of Song nodded.

"Yes, this person's private life is more complicated, according to colleagues' reactions, Zhang Junya and at least three boyfriends at the same time."

Two of the doctors in the hospital have been with her.

Yes, Fang Qing of the Department of Psychology attached to the hospital and Zhu Xupeng of the cardiovascular department.”

He heard the name Fang Qing and immediately raised his head.

This person is his student, is a good relationship, Fang Qing's father and Zhou Hai's mother are colleagues, after returning home Zhou Hai has been busy.

Fang Qing went to Beijing to study for three months, and the two of them have not been able to meet, but have communicated by telephone.

I can’t believe he was involved in this case!

Did you go back to the south?

Chu Menghan then said.

“Other people, we all count the list, people from all walks of life.

Currently, there are six key screenings.

Later, the investigation will be carried out according to the time period given by the medical examiner.

Our second group investigated all the social relationships of the Zhang family.

The old husband and wife of Zhang Heping are more unique in their social relations with Zhang Junming.

The eldest son-in-law is Liu Handong, 35 years old.

It is a big deputy of the Southeast Shipping Company, specializing in international freight routes, we have confirmed their company.

Yesterday morning, his workboat was unloading in Yunlian Port and would need to return to the south-east tomorrow.”

Mr. Liu raised his hand.

“Wait, you said the port?”
