The Rise of the Peninsula

Chapter 101 0095 – Buying a murderer to kill someone

Park Shangyuan also followed in. He was shocked by the scarred spikes on the bark. Sure enough, this guy was here last night.

"Look, Prosecutor Park, these marks should be left by the suspect when he climbed last night, and they are still fresh." Su Shuzhen reached out and placed the magnifying glass on top of the marks.

"Moreover, I have observed all the trees in the vicinity, and I can see only a few trees facing the crime room, and there are no traces on other trees, so I can be sure that this is the tree that the suspect stepped on. .” Su Shuzhen added.

"Judging from the dense new and old traces on the surface of the bark, it is not the first time the suspect has come here, but he should have come here often." Park Shangyuan walked around the trunk.

At this moment, he feels that he is close at hand. This point reduction is definitely not the first time he has come here, but has been stepped on many times, so...

Then buying murder and killing people can also be established.

This is an extremely professional criminal.

Or was it an affair with the deceased's girlfriend?
Park Shangyuan took out the evidence bag and stuffed all the shredded tobacco and cigarette butts scattered under the crooked neck tree into the evidence bag. If DNA can be found through this method, and if this person happens to be in the database It's easy to be so shabby.

So what if he is not in the database?As long as the murderer is caught, then this evidence is ironclad.

After completing the follow-up practice evidence, then this person will be unable to escape, and there will be no movies like the Internet where various suspects finally escape. The reality is not so dramatic.

"Investigator Su, the suspect wore gloves when he committed the crime, but he may not wear them when climbing trees to increase resistance. Is there any way for you to deal with the fingerprints on the surface of this tree?"

Park Shangyuan placed his hopes on Su Shuzhen. It was such a veteran investigator who gave him too many surprises. He has a weird personality, but he treats himself loyally and seriously.

And if this case did not have his help, then presumably this case would never end so soon.

He is his right-hand man.

"Just now I was ready at the unit." With that said, Su Shuzhen walked to the investigation box and took out a large bottle of light yellow powder from it.

"What is this?" Dian Wei is always so curious, mainly because this guy has given him too much sense of crisis.

Now Pu Shangyuan looks at Su Shuzhen with bright eyes, but looking back at himself, he looks completely disgusted.

This made him very much like Mrs. Yazhai, who was married by Ming Media, who was defeated by the very eloquent mistress outside, and felt indescribable in his heart.

"This is a powder I bought from a Chinese medicine store called pine pollen." Su Shuzhen was also unambiguous, and directly picked up a bottle of medicine from his trouser pocket and handed it to Park Shangyuan

"Pine pollen? Why do you use it?" Pu Shangyuan took it by accident, is it a Chinese medicine store?There are some emotional things in it.

Pine pollen is brown powder as a whole.

Su Shuzhen replied respectfully: "It is the dried pollen of Pinus massoniana, Pinus tabulaeformis and other plants of the same genus. Its main purpose is to reduce inflammation and stop bleeding."

"Can traditional Chinese medicine be used to extract fingerprints?" Qiu Xiuzhen asked suspiciously. In fact, this kind of thing is completely beyond common sense, completely beyond her own cognition.

Su Shuzhen smiled confidently: "Of course, as long as you understand the special effects of pine pollen, you will not doubt it."

"All ears." Dian Wei pinched his waist with both hands.

Su Shuzhen unscrewed the jar in his hand: "We know that what remains on the surface of the bark is mainly sweaty fingerprints on the skin of fingers."

"Well, this is common sense." Qiu Xiuzhen looked studious, like a classmate who was keen to ask questions.

"Pine pollen is a kind of light yellow fine powder. When the flowers just bloom in spring, they can be collected by picking the flower spikes and drying them in the sun. It is also a traditional Chinese medicine, and it has a strong adsorption effect on the sweaty handprints on the plant epidermis.

When pine pollen particles touch the sweat fingerprint, the cell wall will combine with the protein in the fingerprint due to the adsorption force, thus firmly sticking the pollen to the fingerprint line. "

Su Shuzhen looked at Qiu Xiuzhen and Dian Wei who were confused, and shook his head helplessly.

Pu Shangyuan glanced at the two of them and added: "To put it simply, pine pollen has a soft spot for fingerprints on plant skins and has a certain affinity."

Dian Wei couldn't tell that Park Shangyuan was teasing him. If someone else said it was good, but what if his boss said it?I can only humbly ask for advice.

"You're so stupid." Su Shuzhen complained.

Dian Wei snorted: "Anyone will say that if you have the ability, you can process the fingerprints on this crooked neck for me. I want to see if this pine pollen is so magical."

"If you're stupid, you have to be open-minded and ask for advice." Su Shuzhen smiled slightly, ignoring Dian Wei who was furious at the moment, put on a mask and walked towards the tree trunk.

He took out the thermometer and measured the outdoor temperature, six degrees Celsius.

Seeing this value, Su Shuzhen put the thermometer back with confidence.

The main reason for measuring temperature is to rule out the presence of freeze fingerprints.

Although it is February, it is winter, and since sweat fingerprints also contain inorganic salts, inorganic salts have a certain degree of water absorption.

When the temperature drops below the freezing point (zero degrees Celsius), the fingerprints will freeze to varying degrees. When the pine pollen fingerprints appear, the fingerprints must be in a liquid state. The current temperature is obviously above the freezing point. In this way, Su Shuzhen's concerns were eliminated.

Seeing Su Shuzhen's godlike look, Dian Wei couldn't understand him very much, while Park Shangyuan looked like he had dug a treasure.

There are foreign methods in foreign countries, and domestic methods in China. I remember that when I went to listen to trace inspection, the professor told me a very classic case.

It's a pity that I didn't remember exactly what kind of method it was at the time, but there is such a method in China that can quickly detect fingerprints.

This made him have to marvel, he seemed to have really found a treasure, this guy has no shortcomings at all, in other respects he is completely an all-around player.

He didn't hear Park Shangyuan's thoughts at all, Su Shuzhen just acted according to his own thoughts, he didn't think so much, he just wanted to solve the case as soon as possible.

The method of showing fingerprints with pine pollen is very foolish, that is, simply and rudely sprinkled on it, without any technical content, and the entire tree trunk was covered with powder by Su Shuzhen in just one cigarette.

Then Su Shuzhen took out the inspection record book and used it as a "fan" to remove the excess powder on the tree trunk. A dozen handprints with yellow powder attached appeared in front of several people.

"You can't see the lines of the hand lines at all, how can you tell?" Qiu Xiuzhen said the key point.

Because if fingerprints want to identify a person, they rely on some detailed features on the fingerprints. Due to the unevenness of the bark, the fingerprints processed by Su Shuzhen can't see any features at all.

Su Shuzhen raised his eyebrows, not worried at all because of this.
