Chapter 1016: Epidermal Glove

There were many people who came to visit this time, including not only the leaders of the direct management agencies of Ningtai County, but also leaders from various investors, as well as some media and non-police system personnel.

Someone with a clever mind took the initiative to stand out, smiling before speaking, and said, "Is Director Jiang going to perform an autopsy on the spot? That... some comrades who came today might not be used to this kind of activity..."

The person in charge of the Taihe Working Group is a director, so Jiang Yuan can now also be called a director.

Jiang Yuan walked to the corpse at this time, shook his head, and said, "I won't be performing an autopsy on the spot. I have recently done some research and industry learning on fingerprint identification for drowned corpses, and I want to show it to everyone. Because it is the Taihe Working Group, many of the cases encountered involve drowned corpses."

"This is good. However, non-police personnel who are not used to corpses can leave first." The leader from the provincial department was very amiable.

Taking advantage of this time, Jiang Yuan slowly put on latex gloves and began to check the items next to the autopsy table.

No one left the scene.

Even the media reporters who came along were knowledgeable. Even if they were a little bit unaccustomed to corpses, they could at least barely persist.

Jiang Yuan was ready, coughed twice, and said, "This corpse was found on the south side of the Taihe River four days ago and was just sent over today. The corpse is male, and the decay is relatively serious... We are now trying to take fingerprints from the corpse."

While Jiang Yuan was speaking, he directly turned on the temporary skill +1.

In this way, the newly acquired LV6 Fingerprint Analysis Method soared to LV7 on the spot.

This level was already a bit unreasonable. The LV6 dog food could make police dogs give up their establishment, and the LV7 fingerprint analysis method even made some impressive fingerprints Jiang Yuan had done before appear in his mind.

This was already a bit like Xu Limin of the 'Eight Tigers of Criminal Investigation.' When he was young, he remembered more than 30,000 fingerprints, and if you asked, it was talent. This was different from photographic memory, because he obviously didn't have such ability when looking at text.

And for Jiang Yuan, he had already tried the LV6 fingerprint analysis method yesterday, and had also taken fingerprints from a corpse, so he was no stranger to the work at hand.

Of course, the difficulty was not small.

The corpse found in Changyang City four days ago was something the Criminal Science and Technology Center of the provincial capital couldn't handle, so they decisively sent it over. Even so, the degree of decay was relatively deep. If it were thrown to the previous Jiang Yuan, it would be unlikely to take fingerprints.

"Usually, for corpses with serious decay, we will try to take an 'epidermal glove.' The forensic doctor at the discovery site has already tried this method, but it didn't succeed." Jiang Yuan introduced while making preparations.

"An epidermal glove is peeling off the epidermis of the corpse and putting it on your hand to press fingerprints, right?" Wu Zhisu, the detachment leader of the Criminal Police Detachment of the Jianjiang Municipal Bureau, was very interested in this and asked immediately.

Many people with police experience have heard of epidermal gloves, but few have seen them, especially criminal police below the provincial capital level. If the local forensic doctor is not particularly strong, they can't play such fancy tricks.

Jianjiang City is covered with water networks, with rivers, lakes, swamps, and big mountains. It has always been a place where water bandits and bandits gathered, and the folk customs are fierce. Although there are no professionals now, the number of homicide cases is not small at all. Jiang Yuan has also solved many cases in the area, including serial murders.

Wu Zhisu is also a policeman who likes new technology and is very clear about the difficulty of epidermal gloves.

Jiang Yuan nodded and said, "After the corpse decays, the epidermis will peel off from the dermis tissue. Through this characteristic, we can peel the epidermis of the corpse off the fingers like a glove, forming an 'epidermal glove.' The peeled epidermal glove is rinsed with clean water and then soaked in glycerin. If the papillary patterns on the fingers are complete and clear, it can be put on a living person's hand and coated with ink for pressing."

The same words, if said in a commercial KTV, would probably get comments like "Eww, so disgusting," but in the forensic building of the police bureau, whether it was a man with a majestic figure or a dignified and beautiful woman, they all stretched their necks to watch.

Next, they heard Jiang Yuan say, "However, because the decay of the hands of this corpse is too serious, it has basically lost the conditions for making an epidermal glove, so we can only use other methods to do it."

"What method?" The reporters at the scene had already started taking pictures after getting permission.

"Although the decay of the epidermis of the corpse is serious, according to my observation, it has not completely rotted away, it can only be said to be shattered. We can try to piece it together. However, there is no mature technical solution for this method." Jiang Yuan did it while speaking.

The reporters were a bit confused and couldn't help but ask the police they were familiar with in a low voice.

Wan Baoming from the Changyang Criminal Science and Technology Center saw this and stood out, saying, "Team Leader Jiang, Director Jiang is using a very difficult fingerprint sampling method. I will roughly introduce it to everyone."

His identity was the most suitable, and the leader from the provincial department smiled amiably. "I also want to hear it."

Wan Baoming then stood out, first humbled himself for two sentences, and then said, "Taking fingerprints from a corpse, according to the degree of decay of the corpse, we generally divide it into four levels. The first level is a corpse without rigor mortis, that is, the fingerprints of a fresh corpse, which is the simplest. The second level is the fingerprint pressing of a stiff corpse. The difficulty in this lies mainly in the stiffness of the corpse's fingers, so that the opening of the fingers is not ideal."

Wan Baoming said, "There are also many ways to deal with stiff corpses, such as soaking in hot water, rubbing with hands to warm them up, all of which can alleviate rigor mortis. The difficulty of obtaining fingerprints from second-level corpses is not high. We also do a lot of this in our daily work."

Wan Baoming: "The third level is a shriveled corpse. This is mainly because the corpse is dehydrated. The treatment plan is generally to inject liquid corpse wax or glycerin. Obtaining fingerprints from this type of corpse has a certain difficulty. We do relatively more of this type of fingerprinting in the Changyang Municipal Bureau, and we often undertake identification tasks sent by other units."

He said this, and those who understood or didn't understand all understood that the third type of fingerprint acquisition method was already the ceiling of Shannan Province.

"The fourth level is the epidermal glove I just mentioned. The principle of the epidermal glove is simple to say, but it is really not simple to do. The difficulty is very high, and the failure rate is also high. Many times, you have to rely on luck. There are not many successful examples in our Changyang Municipal Bureau." Wan Baoming paused and then said, "As far as I know, the country can basically reach the fourth level. What Team Leader Jiang is doing now, there should be no one in the country who has done it."

"There are still successful ones, but there are relatively few examples." Jiang Yuan took over the conversation at this time, introducing while working, "I have now found several pieces of residual epidermal layer, which I initially judged to belong to the index finger, because the epidermal tissue is already very thin. If treated with conventional normal saline or formalin, it is easy to shrink, so I try to rinse it directly with clean water."

Jiang Yuan bent over and operated cautiously, but the specific movements could not be seen clearly.

"Okay, I will now put this piece of epidermal tissue directly on the slide and take a photo to fix the evidence." Jiang Yuan had already picked up the camera when he said this, and after taking the photo himself, he looked at the photo.

Jiang Yuan said it simply, but this was not a simple technical discussion meeting after all. For the police present, this was a practical performance, and it was a technical service that everyone could enjoy after joining the Taihe Working Group.

Thinking of this, many people had already taken out their mobile phones and started to silently contact those who knew the ropes. ===== CHAPTER 1017 =====
