civil forensic

Chapter 174

Talked to the team leader Lei Xin, smoked almost a pack of cigarettes, and several forensic doctors dressed neatly again and continued to dissect the body.

Lei Xin originally wanted to help, but seeing that there was no room, he stood on the side, found a pedal to stand on, and continued to look.

So Cao Keyang has company, together.

Burned corpses are no different than normal autopsies.

For a normal autopsy, if only part of the autopsy is done, it can be done in two to three hours, and for a slightly more complicated autopsy, it may take four to five hours.

However, there is very little information available on the burnt corpses, so a relatively careful dissection is required.

Lei Xin came here on a special trip, and actually has this meaning in it.

The physical evidence left at the scene is close to none, and there is really nothing that can be used.

Although the corpse was burnt to a disastrous state, there were still some things left.

Now Lei Xin hoped that the cause of the suffocation was poisoning. If he could determine the type of poison, it would be a very good evidence clue.

Jiang Yuan took the second place again, but still searched hard.

Niu Dong, who is the forensic doctor of the district bureau, was even more serious. After the abdominal and pelvic examinations, he carefully inspected the limbs inch by inch.

Everyone knew in their hearts that the only thing they could count on now was some small discovery.

Jiang Yuan was tall and tall, and soon bent over to the point of exhaustion. When he stood up and moved, he saw a shiny ball of light slipping out from the chest cavity of the corpse.

Jiang Yuan looked around and reached out to take the light ball.

Zhang Ying's Legacy - Trendy Clothing (LV2):
The eccentricity of the big city and the ebb and flow of the tide gave Zhang Ying, who came from a small place, a severe impact.Those beautiful clothes, which can represent individuality, culture, and art, tempt Zhang Ying again and again, and make her linger on.

The beautiful clothes also gave Zhang Ying unprecedented confidence. For a while, she also caught the tail of popular culture and had some audiences who knew how to appreciate and appreciate her.

Although Zhang Ying, who returned to the small city, has gradually lost her sense of fashion, but in Qinghe City, she is still the top fashionista.

LV2 is a high-level professional talent in a city, and Zhang Ying's legacy seems to be at a higher level in LV2.

However, where can the skill of trendy clothing be used?

Can you judge his identity and origin based on the clothes of the corpse?

After thinking about it, Jiang Yuan looked at the corpse again.

The scorched and curly corpse was naked before being burned, which is also embarrassing.

The autopsy was not completely completed until dawn.

Niu Dong still had to write the autopsy report. Wang Lan, Jiang Yuan, Cao Keyang, and Lei Xin all left in the car to rest.

To be precise, the first three rested, and the team leader Lei Xin continued to go to other places to boost morale.

noon the next day.

When Jiang Yuan woke up, he estimated that all the reports should have been released, so he packed up and went to the criminal police team.

The whole body has changed into brand new clothes.

Still bright police cool, uniform suit, already very good-looking and straight.

Although with new skills, Jiang Yuan doesn't seem to have changed much.

After entering the gate, Jiang Yuan felt a thick and heavy breath.

It's like smoky old bacon, you know what you're eating today when you smell it.

The expressions and movements of the surrounding policemen conveyed the message to Jiang Yuan that the case was not solved, the problem remained, and the clues were cut off.

Entering the office, the breath is still there.A few policemen who looked like old bacon gathered together and discussed in a low voice, probably not trivial things like garlic sprouts.

"Forensic doctor Wang, forensic doctor Niu." Jiang Yuan came to the desk in the corner. This is a relatively flexible desk, which is for criminal policemen like Wang Lan who came to support him from other places.

"Jiang Yuan." Wang Lan nodded.Her eyes were still sharp, just slightly tired.

People in their 40s who stay up late all night may not be able to bear it anymore.

However, this is true for all the police, especially the criminal police in the criminal police team. Once involved in a serious case, stomach medicine and gastrointestinal medicine are necessary medicines.

Jiang Yuan asked: "Did the drug test result come out? Is there anything?"

"There are no common poisons." Niu Dong replied.

Toxicology testing is by portion.

Generally speaking, if you check for arsenic, you will check for arsenic, and if you check for tetramine, you will be testing for tetramine. There is no machine that puts a piece of material in and spits out the result with a click.

For something simpler, like testing for cyanide, you can use picric acid test paper. To do it in detail... It's almost the content of a high school chemistry experiment class.

As for solid-phase extraction, liquid-phase extraction and the like, each has its own complexity.

Therefore, the lack of results in the poison test does not mean that the deceased must not have been poisoned, but it was negative for common poisons.

In the relatively well-known Fudan poisoning case, a dimethylnitrosamine test had to be done separately, and the result was positive before the type of poison could be determined.There are an estimated 60 similar chemicals that are highly toxic to humans.

Jiang Yuan nodded slightly, and said: "Then we still have to leave the relationship?"

When the physical evidence is close to none, then the old methods of the old criminal policemen can only be used.

It's no wonder that several old criminal policemen were discussing with serious expressions and excitement.

Wang Lan only said "En", and said: "The ideal state is the relationship between men and women, which leads to love killings. If this is the case, the difficulty lies in the interrogation. If there is no physical evidence, people will recruit or not. "

"That's right." Jiang Yuan and Niu Dong nodded together.

"If burglary or burglary turns into murder, it will be troublesome."

"really."

This is the most direct reasoning, there is no difficulty, but the conclusion of the derivation is a bit unacceptable.

Jiang Yuan couldn't help asking: "Aren't there any cameras around? A little farther away, at the intersection, it's fine too."

"The urban village here is very complicated. Even if there are cameras, they are all broken." Forensic doctor Wang said.

Jiang Yuan knew it well, and he didn't have the heart to criticize another city's security management problems. This kind of problem in urban villages is already common, so he thought about turning around, and there should be more cameras in Jiangcun.

Committing crimes randomly has always been a difficult point.The reason why theft and robbery are difficult to crack is that its randomness is particularly strong.Anyone can steal or rob anyone, and the ways to solve the case are very limited.

The Zhang Ying case is the same. If you encounter random crimes, then you have to focus on series and parallel connections.

If it cannot be connected in series and parallel to other cases, the evidence in this case alone is not enough to convict, and it is not enough to solve.

The air pressure in the office is relatively low, which is also for this reason.

When a case is completely out of control, the mood of the police responsible for solving it is not good.

Several old detectives quickly finished speaking and went out.

After a while, Lei Xin came into the big office.

After some greetings, Lei Xin came over to the corner of the three forensic doctors, said hello, and updated the three of them on the latest situation, saying:

"The social relationship of the deceased Zhang Ying is quite complicated, and he knew many people."

Forensic doctor Wang Lan asked, "Do you have a boyfriend?"

Lei Xin didn't hold back, and said: "Her hometown talked to a fiancé and gave her a bride price of 18. She also came to Qinghe City to work this year. They heard that there was some conflict. Zhang Ying didn't like each other. The man went to the mall I have come to look for Zhang Ying several times. This is suspect No. 8, and our people have already looked for it."

"Suspect No. [-] is Zhang Ying's leader. He has an ambiguous relationship, but he has a family. He brought him back, but he doesn't look like him."

"This relationship is not enough...then is there anything else?"

Wang Lan stared at Lei Xin and asked.

"Zhang Ying has an outstanding appearance, knows how to dress up, and is a bit aggressive. She doesn't get along very well with her colleagues, and she has quarreled with customers, but it's not serious. She also had a dispute with the courier because of the delivery of the courier. She was compensated. several hundred."

Lei Xin is in a state of desperation, these are normal social interactions, not special.

He looked at Jiang Yuan, who never misses out, Lei Xin said in a good-tempered manner, "Can Forensic Doctor Jiang go to see the scene if you have time?"

He had the idea of ​​sifting out as many clues as he could.

Jiang Yuan responded with one gulp.

The autopsy he most wanted to do was to be done, but the case was not over, and those who should help still needed to be helped.

Lei Xin hurriedly expressed his thanks, and then left in a hurry.

Jiang Yuan then called Wang Lan's forensic doctor, and specially called a criminal policeman, and they went to the crime scene together.

After actually experiencing the murderer's return to the crime scene, Jiang Yuan dare not take it lightly.

Even with two technicians, he felt that it was not very safe.

During the investigation of the crime scene, the technicians are all focused on the ground or objects, and they don't notice people coming from behind.

With two technicians as companions, the safety factor is not very high.

But it is much better to have a non-technical policeman. Even if he is holding a mobile phone and watching short videos at the door, it is safer than having one more technician.

The self-built houses after the burnt down were dirty and dark.

The beams fell in the middle of the house, and the ruins looked like they had been through the flames of war.

"The one who wants to kill the most now is probably the landlord." The criminal police who came with him walked to the entrance of the yard and didn't want to go in.

The so-called collapsed houses, self-built houses after being burned, have nowhere to go from the outside door.

There were a few boring people at the door, looking around with their heads poking around, but they didn't leave without saying a word when they were driven away.

It wasn't until the criminal police took out their notebooks to write down their ID cards that they hurried away.

Jiang Yuan and Wang Lan put on masks, especially foot covers, and then went inside for a little investigation.

Two hours later, Jiang Yuan basically gave up.

No fingerprints, bloodstains, or footprints were found at the scene after the burning. It's really no wonder that the survey was not working hard.

It is trace evidence, which cannot be found in this environment.

Not only biological samples will be denatured, but also common fibers and other substances cannot be preserved.Even metals can be oxidized.

"I can only look at the physical evidence obtained from the fire point. Can we find clues?" Jiang Yuan took some physical evidence, but he was not very confident.

As soon as he walked out of the door and was still taking off his gloves, the policeman at the door walked in quickly.

"Slow down, slow down, the ashes are rising." Wang Lan shouted quickly, and then asked, "Any new news?"

"There are clues from Zhang Ying's hometown." The policeman responded, and said a little excitedly: "It turns out that her family has another marriage, and the bride price is 28. When we went, the three families were arguing."
