"Let's do on-site inspection first." Jiang Yuan waved his hand, still working in a serious manner.
Zhan Kong couldn't help but concentrate.
When he recalled the work he had done just now, even if he had some foreknowledge, he could still only say that it was unremarkable - but after listening to Jiang Yuan's conclusions of one, two, three, four, five, he could not use the word "extraordinary" to describe what he had just done.
It would be too strange to participate in the survey.
Judging from his status as a forensic doctor, it was more like a thunder on the ground.
However, even if Zhan Kong is given another chance, he still cannot find anything beyond the ordinary in Jiang Yuan and his work itself.
It's really just an ordinary, ordinary job, and the body's behavior is also ordinary, ordinary.
Zhan Gong has also been a forensic doctor for several years, and he is a high-level professional, but he still can't fully understand Jiang Yuan's conclusion - the content of the conclusion is naturally clear, and the condition is that he follows Jiang Yuan step by step.
What came out was just how to change from "known" to "inferred from this", which he couldn't figure out.
Jiang Yuan didn't have time to explain, so he carried out the investigation step by step.
On-site investigation is inherently a meticulous job, and the higher the level of on-site investigation, the higher the level of detail.
When doing ordinary on-site surveys, targets are often selected at fixed points. Just like the famous cattle forensic doctor in Qinghe City, when he entered the scene in the early years, he didn't look at anything and first collected toilet paper and the like.
Even by scanning fingerprints, the investigators cannot look at everything inch by inch. Most of the time, they just look at the positions of doors and windows, door handles, drawer handles, and the surrounding areas of lost items. For ordinary small cases, they can get
An hour or two of attention to the current survey is very good.
When it comes time to scan inch by inch, you have to identify the source of fingerprints or DNA and whether it is contaminated, which requires a higher level of on-site investigation capabilities.
Jiang Yuan finished sweeping the bedroom and then moved on to the living room. He took samples when it was time to take pictures and took pictures when it was time to do so. It was like being a field surveyor again. It wasn't that he didn't trust the field surveyors from the Zhengguang Bureau, but everyone had different understandings. He now
It was already done purely as a murder case. On the other hand, there were already many people involved in the on-site investigation, and it would not be wrong to have one more person doing the work.
"Did you find anything?" Liu Sheng waited until Jiang Yuan started to take off his gloves again, and hurriedly came over to ask.
"I can't say yet. I have to go back and take a comprehensive look." Jiang Yuandao: "I'm going to the anatomy center."
"Okay, okay." Liu Sheng responded repeatedly, and then said: "I will stay at the scene for a while. If you have news over there, I can give you feedback in time."
When Liu Sheng came across a current murder case, he was ready to stay up late.
Not to mention that this case was named by multiple leaders, even if the suspect was left at the scene with a murder weapon and a murder of passion was discovered, the criminal police might have to stay awake for days and nights to fix the evidence and interrogate it.
,Documents...
Mu Zhiyang drove Jiang Yuan and Zhan Kan directly to the anatomy center.
The body of the victim Zhou Xiangyang arrived earlier and was already lying on the cold stainless steel bed.
Several available forensic doctors came over and were waiting to see Jiang Yuan's autopsy.
Jiang Yuan rarely had such an experience, and couldn't help but praise: "It's really good that you have such an anatomy center, with so many colleagues working together."
"You can ask for an anatomy center." Zeng Lianrong, an old forensic doctor, obviously knows a lot of information.
Jiang Yuan smiled and said: "In Ningtai County, there are two forensic doctors including me, and my master is about to retire..."
While talking, the layout of the anatomy table has been completed.
The corpse was placed straight on the table.
The old man was more than 1.7 meters tall when he was alive and had a thin body. Now he has turned into a corpse. He is a type that is more popular among forensic doctors. If he cuts it with one knife, the fat will not be released, and it will not be too hard to cut.
"Record the time, and then... now there are dark purple-red corpse spots. If it is rigor mortis, it is distributed in all joints of the body. The bulbar conjunctiva is pale, and the junction is congested..."
Jiang Yuan did another physical examination before raising the knife to make an incision.
Zhan Kun quickly put down his notebook and came to assist, while a forensic doctor next to him obediently picked up his camera and started taking pictures.
There is a video of the entire process in the anatomy room, but the precision is definitely not as good as taking photos. The most important thing is that the angle is different, and sometimes the reflected content is different.
Zeng Lianrong is a veteran in the anatomy center, so he only needs to stretch his head and look.
He has collaborated with Jiang Yuan on two cases before, and the process of understanding each other has been completed, and he is currently in a learning state.
Seeing Jiang Yuan open the three chambers, Zeng Lianrong naturally leaned over and carried a bucket to Jiang Yuan.
Forensic doctors all like to use buckets to store organs such as the stomach, heart, and lungs. If they are easily spilled in a basin, the forensic doctor will also feel nauseous. This will also affect the accuracy. Furthermore, some people eat too much or have cardiopulmonary hypertrophy.
The loading capacity will also far exceed expectations.
As the saying goes, if you don't open a person's stomach, you don't know how many bowls of jelly he can stuff in his stomach.
"A small amount of light red foamy liquid can be seen in the tracheal cavity..."
"There is still a lot of fluid in the stomach..."
"Patchy bleeding can be seen under the pancreatic capsule..."
"There is homogeneous pink-stained edema fluid in the alveolar spaces..."
Having said this, Jiang Yuan looked up at the other forensic doctors and said, "In this case, it should be considered that he died of poisoning."
Zhan Kong was still in a daze, but Zeng Lianrong nodded in agreement.
Whether death by poisoning is considered is related to whether poison testing should be done immediately and how detailed the testing is. The most important thing is that if it is judged that death is caused by poisoning, heart blood must be taken immediately to prevent the poison from being metabolized in large quantities.
Although the sensitivity of current toxicology tests is already very high, there are too many types of poisons that cannot be tolerated. There are always some poisons with small residual amounts.
Moreover, unlike what many people imagine, toxicological examination does not mean putting poisonous blood into the instrument, and the instrument will beep and give the answer. In essence, toxicological examination is still a comparative process.
, the instrument does contain data on some common poison ingredients. To a certain extent, it can beep, but for slightly more remote poisons, it is necessary to compare and analyze them one by one, which has its own difficulties.
Jiang Yuan also quickly took the heart blood, filled it with stomach contents and urine, and sent it to the toxicology laboratory on the spot.
Next, several people carefully checked whether there were external injuries, needle holes, etc. on the body, and then completed the rest of the autopsy.
When the time was almost over, a ball of blue dumplings rolled down from the corpse's mouth to Jiang Yuan's hand.
Zhou Xiangyang's legacy - cryptography (LV5) - Zhou Xiangyang has been a genius among the crowd since he was a child. He was like this in elementary school, middle school, and high school. Until he entered college, he was still at the top, which made him always
Consciously seeking challenges. Cryptography is perhaps the most competitive of all disciplines, especially when he first entered this field. The world was competing for hegemony and the demand for cryptography was endless. The future of cryptography
It seems infinitely broad... In recent years, more and more commercial value of cryptography has been developed. The development of new Internet technologies such as blockchain has enabled Zhou Xiangyang's students to always receive extremely high salaries.
, but Zhou Xiangyang himself gradually began to feel bored. Making money was not his original intention of learning cryptography.
Jiang Yuan sighed secretly. After the examination was completed, he quietly stitched up Zhou Xiangyang's body. He thought to himself that even as a corpse, the mystery of Zhou Xiangyang's death was top-notch. He only hoped that he could crack his death code.
"Call Tao Zhi for me." Jiang Yuan held his hand and turned to the forensic doctor next to him.
The forensic doctor next to him quickly dialed the number and put the phone next to Jiang Yuan.
"Tao Zhi." Jiang Yuan waited for the call to be connected, and then said: "Zhou Xiangyang's autopsy has been completed. The cause of death has not yet been determined, but it is most likely that he died from poisoning. His blood has been sent for toxicology. I noticed that he is now
The project I am doing is related to cryptography, please see if you need to notify the National Security Bureau."
