Advocate for the deceased

Chapter 17 The Girl in the Forest (9)

After the fat man went through the relevant procedures, he came back swiftly.

Recently, under the influence of Zhou Hai, he became very interested in dissection, and the three of them changed their clothes and washed their hands and appeared in the dissection room.

Xiao Liang opened the body bag, and immediately backed up three or four steps with an exclamation.

"what!

God!

she~
she~
Keep your eyes open~"

The fat man bumped Xiao Liang with his shoulder, blinked his small eyes and said.

"Hey!

Boy, don't be surprised, haven't you ever heard of death without peace?

I was not scared to death by the dead, but scared to death by you. "

Zhou Hai glanced at Xiaoliang.

"The week of the eyelid is the orbicularis muscle.

After the body dies, all muscles relax.

With rigor mortis, the eyelids open slightly.

However, like Ma Keke, it is rare to see his eyes widen, and it is a small probability.

I suspect it has something to do with her state before she died. "

The fat man pushed aside the trabeculae that were blocking him, and swallowed a mouthful of saliva.

"You mean, before she died, her eyes widened in horror, so now she seems to be frozen?"

Zhou Hai nodded.

"The killer parted her hair just to hide her eyes.

When the acquaintance committed the crime, out of guilt, he did not dare to look directly at the deceased. "

The three of them worked together to remove the clothes from Marco's body, and put them on a nearby table in order.

"It's a pity, such a beautiful girl."

The fat man smacked his mouth as he spoke.

Zhou Hai ignored Fatty's words and started the autopsy.

On the front of the half-sleeved school uniform, there are some debris of tree trunks.

Because Ma Ke died of mechanical suffocation【1】, he passed out urine and feces, and his clothes and pants were stained with excrement.

The shoelaces on the wrist and neck of the deceased were removed, and the way of winding and knotting was photographed, and they were put into evidence bags for inspection.

Zhou Hai pointed to the knot where the knot was tied and explained.

"look here!

The way of tying the knot is the same as the knot left on Zhong Yishan's wrist. "

The fat man wrinkled his face and twitched the corner of his mouth.

"Based on this knot, you conclude that Zhong Yishan and Marco were killed by the same murderer?"

"That's just part of the reason.

The choice of the murder scene, and the method of repeatedly confirming whether the deceased is dead, all reveal that they are the same murderer! "

"Zhong Yishan, didn't she die from hemorrhagic shock?

And this one was strangled to death, the difference is quite big. "

Zhou Hai glanced at Fatty and Xiao Liang beside him.

"Remember the knife in Zhong Yat-shan's Perineal part (his own Baidu)?"

The two nodded.

"Remember!"

"The murderer does this,

One is out of hatred.

There is another more important reason,
It's her confirming,

Is Zhong Yishan really dead?

Xiaoliang, send the bundled objects and the samples collected on-site for inspection.

The murderer didn't have time to clean up the scene, if the murderer didn't wear gloves.

Then on the shoelaces, it is possible to extract the murderer's DNA.

Remind Sister Zeng that it must be compared with the DNA of those people extracted yesterday. "

Xiaoliang ran errands and sent all the samples upstairs for testing.

The autopsy was carried out next, and Ma Keke's face was swollen, the skin of the face and the conjunctiva were spotty, and he was discharged from urine and feces, all of which are typical features of strangulation.

Zhou Hai sliced ​​open Ma Keke's neck, chest and abdomen, and checked the organs in the viscera in sequence.

"The upper corner of the thyroid cartilage was fractured, and the dark brown subcutaneous hemorrhage was obvious in the legou, and there were four deep legous in total."

Congestion occurred in right atrium, ventricle, liver and kidney.

Pulmonary congestion and emphysema are very obvious, serosa and submucosal spotting of internal organs, and the blood is dark red and flowing.

The contents of the stomach are only a small amount of fiber and chyme, and the time of death is more than six hours after the last meal.

Combined with the rectal temperature of the corpse, Xiao Liang calculated the death time of the deceased.

Do you know the formula for calculating the time of death based on body temperature? "

Xiao Liang nodded. He was familiar with these basic knowledge.

"Time elapsed after death = 37 - cadaveric rectal temperature divided by 0.38 multiplied by the coefficient.

(Coefficient: 1 in spring and autumn, 1.4 in summer, and 0.7 in winter)

After calculation, the time of Marco's death was between 4:30 and 5:00 in the morning today, four hours from now. "

Fatty blinked his eyes, he knew that Zhou Hai was asking Xiao Liang to tell him.

"That is to say, the light that the security guard saw was really emitted by the murderer."

Zhou Hai nodded, and checked the body of the deceased.

As expected, he took a swab【2】to wipe and put it in the evidence bag, and looked up at the fat man.

"The CN membrane is old and lacerated, this needs to be sent for inspection."

The fat man pouted.

"I go!
This shows that your previous judgment was correct.

Ma Keke's parents, fully aware of what their daughter did, encouraged her to be with Zhang Yang! "

Zhou Hai nodded, feeling a little heavy.

The perception that money is paramount has already brought today's boys and girls into contact with the dark side of society prematurely.

It is also a tragedy for Marco to be born into such a family.

Zhou Hai carefully sewed up the body of the deceased, trying to keep the integrity of the body, after all, she is such a beautiful girl.

February 6 at 25:11 am
Back in the office, Zhou Hai stared at a photo of white leather on the computer screen in a daze.

The fat man stood behind Zhou Hai, drinking water, shaking his legs while stepping on the stool.

"I said Haizi, you have been staring at this photo for half an hour.

What information do you see on this?

Those who didn’t know thought, which girl gave you a gift! "

Zhou Hai suddenly turned his head and stared at the fat man.

girl!

Yes, why didn't I think of that just now?

"I know who the murderer is!"

The fat man drank the water without swallowing it, and was so frightened by Zhou Hai that he spat it out.

"Cough cough!
If you don’t wear it like this, people will be frightened to death, you know!
But who is the murderer? "

Zhou Hai pointed to the white leather in the photo and said, "Wang Yu, this is the decoration on Wang Yu's shoes."

Before the fat man was surprised, Xiao Liang rushed into the office of the second group.

"The result came out?" the fat man raised his eyebrows.

"Well, the test results came out."

Xiaoliang was a little excited, and he handed the result to Zhou Hai.

"A person's DNA was found on Ma Keke's shoelaces and fingernails. You will never know who it is!"

"..."

The two of them stared at Xiao Liang for a moment, Zhou Hai frowned and thought for a moment.

A bunch of crows flew over Xiao Liang's head.

Why is there no response?

The fat man patted Xiaoliang's head.

"Don't worry about it!
Your Brother Hai figured out who the murderer was before you came in. The report you brought is just evidence, DNA from fingernails and shoelaces.

It's Wang Yu's, right? "

Xiaoliang's eyes widened and he pushed his black-rimmed glasses. Xu Biao's words were several times more surprising than when he got the report.

"what?

Oh!
But how did Brother Hai guess? "

The fat man waved his hand and slapped Xiao Liang again.

"Guess, guess, guess your size!
This is rigorous forensic analysis, learn from it, kid! "

Xiao Liang curled his lips and didn't say anything else. Zhou Hai took the report and looked at it, then grabbed his cell phone and dialed the number of Wang Detachment.

"The murderer who killed Ma Keke and Zhong Yishan was Wang Yu.

It's time to catch someone! "

　【1】Mechanical asphyxia:
　　Mechanical asphyxia refers to asphyxia caused by breathing disorders caused by mechanical stimulation.Physiological dysfunction caused by mechanical action hindering human respiration, resulting in hypoxia and carbon dioxide accumulation in the body.

　　There are many ways to cause mechanical suffocation, such as neck hanging, strangulation, choking, oppressing the mouth and nose, or compressing the chest and abdomen, and foreign objects or drowning entering the respiratory tract.Death from mechanical asphyxiation occurs relatively quickly and is often used as a means of homicide, suicide, and homicide disguised as suicide.

　　【2】Swab: It is usually used as a tool for medical examination to collect microorganisms, exfoliated cells or secretions.Similar to cotton swabs.
