Let you give a gift to the girlfriend of the police flower, and you give a wanted criminal

"Yes, the water may have washed away the fingerprints on this bottle."

A forensic doctor looked up at the dead man with a bottle, nodded and had a conversation.

Yuan Shu, bring all the suspicious evidence back for testing.

Seeing what he said, Gao Yanbo took a step inside and ordered all the forensic personnel.

All forensic personnel responded immediately and carefully collected evidence.

Come over to listen to Gu's preliminary autopsy report, and then walk towards the dead man.Before he walked in front of the dead, two high-end perfumes got into Su Yan's nose in an instant, and the results were analyzed.

One is a fragrance for high-end women, which is very popular among high-income women.

One is a high-end men's fragrance, but this fragrance is the exclusive love of many playboy men.

Distinguishing between the two smells, Su Yan memorized the smell silently, then walked up to the dead man, knelt down and observed carefully.

The deceased was beautiful and graceful, with long black (good money) hair, a floral dress, and a pair of crystal high-heeled shoes at his feet.

There are no obvious moles on the face, and there are a pair of delicate pendants on both ears.

A precious bracelet is worn on the right wristband.

Many long skirts are torn, which symbolizes that there are several suction marks on the female parts, which are heavy and deep.

Sure enough, the case took a turn for the better.

After watching the appearance of the deceased, Su Yan thought silently in his heart. In addition, the old case I saw yesterday ten years ago automatically came to my mind.

The victims of the two cases share some similarities, but also some differences.

"Su Yan, did you find anything?"

Seeing him squatting among the dead for a while, Liang Xiaorou stepped forward and asked.

As soon as she spoke, both Gu and Gao Yanbo turned their eyes to him.

Everyone wants to see if the crime-solving expert has made...unique discoveries.

"Look at the deceased. Is it similar to the deceased in the old case I showed you yesterday?".

Chapter 302 The Perverted Serial Killer!

Su Yan pointed at the deceased and turned his head to ask.

Hearing this, Liang Xiaorou hurriedly took two steps forward, looked at the deceased carefully, and then said to Su Yan with a solemn expression.

"Their vital parts were all sucked and suffocated. There were no obvious marks on their faces and necks. It was the same murderer!"

"Officer Su, do you think this is the village road infringement homicide case ten years ago?"

Gao Yanbo asked in his heart.

Gu Ze looked at the three of them with water.

"Gao, you have also seen the old case."

Su Yan nodded.

"Well, in my free time, I'll look through the deposition files to see if there are any clues. Forensic medicine couldn't do it back then, but now technology advances may be able to do it. This case impresses me deeply.

The murderer's body fluid is asexual fluid, which cannot be detected with the skills at the time, but now this problem has been solved.Unfortunately, no bodily fluid samples were left. "

Gao Yanbo nodded, and at the end, he shook his head regretfully.

"In this case, the deceased was obviously violated, that is to say, if the body fluids are checked, it will be known whether it is the same murderer."

Shuozi standing aside thought for a while and said.

"It's not that simple, the killer's bodily fluids were not detected at the time.

Even if the murderer in this case has no children, 813 cannot prove that it is the same murderer, but judging from the modus operandi of the two cases, it should be the same person.

Gao Yanbo shook his head while explaining, and finally made a judgment.

"That's right, whether it's the modus operandi, the traces left on the key parts of the deceased, and the chosen target, it can be determined that the two incidents are committed by the same person. Besides, I suspect that the murderer should have just returned to Gancheng."

Su Yan agreed.

"Why did you say that"

Liang Xiaorou was stunned for a moment.

Gao Yanbo and Shuozai also turned their gazes to him.

Gu Ze pondered and said: "Su Yan, are you saying that this murderer is the perverted serial killer who committed the infringement case ten years ago? According to common sense, this kind of person will continue to commit crimes unless he is brought to justice, but in recent years, in Gancheng No similar case happened. That is to say, the murderer left Gancheng after committing the crime that year, and there are still such cases now.

"Yeah, Chen is right, that's what I mean. Besides, we must catch a murderer who is mentally ill like this as soon as possible, otherwise there will definitely be another victim."

Su Yan nodded.

"Our forensic doctor will test the evidence as quickly as possible and provide it to you as soon as possible."

After hearing this, Gao Yanbo said immediately.

"After the body is shipped back, I will conduct an autopsy immediately and give a complete autopsy report as soon as possible."

Gu Ze nodded.

"Okay, I'll find an application to investigate the two cases together as soon as I go back."

Liang Xiaorou nodded.

"By the way, it's best to contact Interpol and ask which country has had similar cases in recent years. The deceased is an oriental woman. As long as this can be found out, we can know where the murderer came from, which will facilitate follow-up investigations."

Su Yan added.

"I see."

Liang Xiaorou nodded.

Then the body was transported to the forensic department first, and Gu left first.

After collecting evidence, Liang Xiaorou ordered the team to go back.

Back at the police station, Liang Xiaorou immediately asked Shen to join the criminal police, asked if there were similar cases in other countries, and investigated the information of the deceased.

Immediately, he and Su Yan went to the forensic department.

When they arrived here, Gu was still in the autopsy room.They put on their hazmat suits and went in.

"How's Aachen? What's there?"

Liang Xiaorou asked as soon as she came in.

Gu, who was standing next to the corpse, pointed to the private parts and said: "The deceased's private parts were at 3:9 and 99:[-]. There were severe tears and bruises, which should be brutal violations. Moreover, I have collected the murderer's bodily fluids, Sent to the forensic department for testing."

"Then we'll find the murderer."

Liang Xiaorou asked with bright eyes.

"But when I collected the bodily fluids, I smelled a strong chemical smell. I suspected it was bleach. In addition, the obvious features of the deceased, those sucking marks also smelled of such a chemical."

(aebc)

Gu Ze shook his head.

"Bleach, the murderer is perverted enough."

Liang Xiaorou shook his head and said depressedly.

"The murderer was not only perverted, but also cunning and clever, and bleach would kill it.

So even if we find bodily fluids and saliva left by the killer, it's useless.

Gu Ze said solemnly.

"This murderer is not simple."

Liang Xiaorou sighed and said.

"Furthermore, the deceased died of asphyxiation, but there were no marks of choking, capping or choking on his face or neck. Also, his nostrils were cleaned. I really can't figure out what the killer used."

Gu Ze said, then walked up to the dead man's head, pointed to the two parts, and shook his head in confusion.

"Then if the murderer covered the entire head of the deceased with something big, wouldn't it leave traces?"

Liang Xiaorou thought for a while.

"Do you mean things like pillows? But no matter what kind of murder weapon, you have to press hard to suffocate the deceased. Once pressed, there will be more or less marks left. But some marks will be a few days after the death of the deceased. It will appear. If there is, it will take a few more days to find out."

Gu Ze propped his chin and said, thinking of another possibility.

"I read a case in a case book. The deceased was also suffocated without any trace. I didn't know it was used until the killer was caught"

Su Yan, who had been silent all this time, spoke very slowly, but was interrupted before he could finish speaking.

This method was not something he read in a book, but something he learned by accident in the original world.

Gu Ze and Liang Xiaorou asked eagerly, "What can I do?"

Su Yan looked at them twice, and replied: "Water and paper. The murderer covered the mouth and nose of the deceased layer by layer with wet paper. In the end, the deceased could not breathe and died."

"What a pervert."

Liang Xiaorou said indignantly when she heard the words.

"If so, that would explain why the murderer washed the nose of the deceased. The purpose was to keep us from knowing what he was doing."

Gu Ze suddenly realized and explained.

"The murderer must be a pervert, otherwise he would not have committed such a crime."

Su Yan first replied to Liang Xiaorou, and then told Gu Ze.

"I have a feeling this murderer didn't use paper, but something that could be collected more easily, but with the same effect."

"Why did you say that"

Gu Ze was stunned for a moment and asked in puzzlement.

Liang Xiaorou also looked at him puzzled, wondering why.

"A perverted killer like this usually likes to take some things as trophies. The deceased has no obvious parts defects, and the murderer chooses this method to kill the deceased. This is undoubtedly a work of pride in the eyes of the murderer, so it is very likely that he will Take it away as a trophy. When he has nothing to do, he will recall the murder and satisfy his perverted psychology and needs.".

Chapter 303 Very High Anti-Investigation Capabilities

Su Yan explained slowly.

"It's true. I've seen some briefings of foreign perverted killers. Most of the murderers took the loot and kept it. But if it's paper, it's really hard to preserve it after it's wet with water. So what is it?"

After hearing this, Gu Ze nodded in agreement, and finally fell into ~endless pain.

"What the hell? We'll find out when we find the killer.-"

Su Yan didn't care much about this.

As long as he knows the technique, sometimes the specific weapon does not affect his judgment in his opinion.

Does Su Yan have a psychological portrait?

After hearing this, Liang Xiaorou thought about it and asked.

As soon as she said this, Gu Ze immediately stopped his hard thinking and turned his gaze to Su Yan's side, wanting to see what his portrait would be.

"The murderer is between the ages of 30 and 35, has anxiety and insecurity, hates certain women, looks good, has a high degree of education, and has financial strength. Even if he doesn't, at least he thinks so on the surface. He has very High counter-detection capabilities, or he just doesn't do anything, looks plain and lives in the dark, but that's very unlikely."

"Uh, why are there polarized life situations?"

After listening, Liang Xiaorou looked at him in a daze, very puzzled.

This is the first time Su Yan gave such a psychological portrait.

"Yeah, how come there is such a portrait this time?"

Gu Ze also asked in puzzlement.

"I'll explain it slowly. From his skilled modus operandi and the old case ten years ago, his age can be roughly inferred. In addition, the murderer can think of using bleach to destroy it.

Coupled with tactics, it can be seen that his anti-reconnaissance ability is very high.
