Chapter 137 Found it! Disappeared fingerprints!

On the top floor, there is usually no one here, only the proprietress comes up to water the plants.

But. Now there are a few strangers here.

Two bodies, one murderer! The other party broke into the room by prying the lock! Xu Hao walked to the door, picked up the padlock, and looked at the traces inside with a solemn expression on his face.

"Traces of damage on it"

"It's very small, almost negligible. If the murderer hadn't suggested at the first scene that he would pick the lock, we wouldn't have discovered it after a careful inspection."

Qian Hua took a step forward and spoke in a deep voice.

The padlock is a kind of iron lump lock, and almost every household in the countryside has one during this period.

This lock is easy to pick.

But the problem is that it is not easy to pry open the lock with minimal damage or even no damage! The general lock picking seems to be just a few tools, and the lock is opened with a snap, which has no effect.

But in fact, there is damage.

The focus is mainly on the keyhole, lock core and lock body. If you want to pick the lock, the lock body can be ignored.

But the lock core is damaged, as long as it is not opened with a key! However, the murderer minimized the damage. His method is almost not like picking the lock, just like opening the lock with a key normally! If it were not for the police dog and the careful inspection by the police, it would not have been discovered.

"Go to the murder scene."

Xu Hao glanced at the police officers who were packing the corpse's bones, shook his head and walked out.

There is very little information about the body dumping site. There are no clues or traces in the greenhouse, let alone outside.

As for the murder scene, it was not far away, within ten meters of Xu Hao.

The third floor was where the deceased Zhang’s family rented.

At this time, a group of policemen surrounded the place and searched everywhere.

There were other residents around, with expressions of fear and curiosity on their faces, and they were talking to each other in a buzz.

Pushing through the crowd, he walked into the house.

There was blood everywhere at the scene!

The floor and the bed were filled with a strong smell of blood! "The dismemberment scene was mainly inside the toilet, and most of the blood flowed into the sewer pipes."

"The murderer then used one or more knives to precisely chop up the body."

"According to the police's estimation, the murderer dismembered the body very quickly. He was like a butcher cutting up an ox. He was familiar with every part of the human skeleton and could find the most suitable and easiest angle to cut!"

Qian Hua looked at the tragic scene and said in a deep voice.

"Are you a doctor?"

Li Jianye was suspicious and thought about it.

Being familiar with the human skeleton is likely related to medicine, but the problem is, "even a doctor wouldn't cut up a body so neatly."

"At the same time, there is no reason for a doctor to have the ability to climb the wall to the third floor and pick the lock with his bare hands."

Xu Hao stood at the window and said something.

He leaned out and looked.

The wall outside the window is not stable. With the presence of a balcony and an air-conditioning unit, it is not something that ordinary people can climb.

"This is a"

"A very professional murderer."

Xu Hao paused and uttered a very surprising word.

"Professional?" Li Jianye frowned.

"Like a killer?"

"Similar." Xu Huo said.

This is a thief.

But this thief has extremely advanced lock-picking skills!

At the same time, he can climb up to the third floor with his bare hands, and he has the means to kill people accurately. He can dismember people more skillfully than a butcher who kills pigs! He is very professional and can be called a professional criminal.

What kind of conflict does such a person have with the deceased? Moreover, what does he do with the money? Judging from the method, the other party has such skills and is not short of money.

Does the thief need money? In fact, the diligent thief is not that short of money. With his skills, he can earn as much as others in a month in one day.

There is even less reason to focus on the deceased's money.

Until "sizzle~"

"Boss, we have a clue!"

In a trance, a slightly harsh voice came from the intercom.

Everyone paused, their eyes focused here.

"Speak." Qian Hua uttered a word.

"Based on what Consultant Xu said, we quickly received several clues from the back office."

"Eventually, we identified one of them."

"The person who called the police on the morning of the 1st, according to him, the cold storage company had serious problems with the refrigerated food due to a personal issue."

"But the other party disappeared and could not be contacted. He was suspected of absconding from the crime."

"Not long ago, the office staff brought a police dog to re-investigate the alarm incident, and the police dog finally found a body by the lake!"

"It has been confirmed that the other party is the missing person!"

When these words fell from the intercom, everyone was silent for a long time, until... "Let's go!"

The crime scene reappeared.

The third crime scene! Three cases occurred in less than a day!

This is simply unbelievable. It was 6:30 that afternoon.

When Xu Hao and others rushed to the location mentioned by the office staff, they saw this scene.

A frozen person, with his hands on his chest, kneeled on the ground, curled up, his facial features expressionless due to stiff muscles caused by hypothermia.

This is a naked corpse.

A naked corpse without even any underwear!

There was ice on the surface of the body, and there were still water stains in the thick hair. The fat belly began to swell, giving it the appearance of a giant.

There was a lake surrounding the crime scene and the body knelt down by the lake and eventually froze to death.

In addition, there is a water scoop.

"Preliminary judgment shows that the murderer killed the third victim on the night of the 31st or in the early morning of the 1st."

"The other party first took the person to the lake and asked him to take off his clothes."

"Soon after, the third victim curled up and fell to his knees due to hypothermia in the cold weather."

"At the same time, the murderer used a scoop to fill the icy lake water in sub-zero temperatures and poured it over the victim's head. The icy lake water flowed from the top of the head to the entire body."

"Ultimately, he became an ice man."

The police officer in charge of the on-site investigation spoke up.

Linlan City is in the south, but it is December now, in winter, and it is also the time when the cold wave hits! In addition, the weather is much colder than in the previous life, so after a rain, on the 1st, a cold wave hits, the temperature drops below zero, and a person freezes to death outdoors.

"During the daytime of the 1st, the murderer's body was most likely covered with a layer of ice."

The other party said again.

Xu Hao listened, then he squatted down and looked at the fat corpse.

When I moved the two pairs of hands, I found that the tendons of both hands were cut, as were the tendons of both feet.

At the same time, the fingerprints of both hands were wiped off with a knife.

The deceased was named Zhao Qiao, in his forties, and was a cold storage guard at a refrigeration company.

But now he died here, frozen to death.

The murderer brought him here and cut the tendons of his hands and feet, leaving him unable to move.

Then, in the hypothermic environment, cold water was poured layer by layer.

The cold water froze into ice, covering the body surface, and the whole person seemed to have become a human-shaped ice sculpture! Even now, the ice residue on the body has not completely melted.

"Why isn't the third scene a dismembered body?"

After the investigation, Li Jianye wrapped his coat around him and raised a question.

"At the first scene, the body was chopped up and then coated with egg liquid and bread crumbs to become fried chicken."

"At the second scene, the body was also chopped up and used as fertilizer in the vegetable field."

"At the third scene, the body had no missing parts!"

Li Jianye began to summarize, with a puzzled look on his face.

"Why wasn't the body at the third scene dismembered?"

“It turned into an ice sculpture.”

"The deceased were not angry with each other because of one thing? If not, the probability is too small."

The probability of five familiar people being killed by one person for different reasons is very small.

It can be completely ignored.

“Fried chicken, vegetable garden, ice sculptures.”

“Is there a commonality among these three locations?”

Qian Hua asked.

Xu Hao fell into deep thought.

The murderer obviously came with some purpose.

He is very targeted! But why are his killing methods so scattered? "Have you found out the identity information?"

Xu Hao frowned and thought.

He squatted down and looked at the peaceful and stable features of the corpse.

"The facial features of the body are very clear. After being refrigerated by cold air, the body looks almost the same as before death."

Hearing this, the people around shook their heads and said, "The cold storage company did not provide a valid contract."

"The other party said he was a cold storage keeper, but in fact he was just a security guard. The company wanted him to take the blame."

"The clothes and identity information were taken away by the murderer."

Please...collect 6_9_book_bar (Six//Nine//Book//bar)

"The clerk searched the deceased's rental house for a while and only found traces of the murderer stealing property, but did not find any other clues that could prove his identity."

No clues again. No clues again! Is it so difficult to check identity information?

Li Jianye frowned and thought, but before he could speak, he said, "Check for fingerprints."

Xu Hao glanced at his hands and said casually.

"The fingerprints were wiped off." Qian Hua shook his head, "Including the layer of skin on the fingerprints, which was cut off by the murderer with a knife. This happened to all ten fingers."

"All we want is to cut off the fingerprints!"

Xu Hao said decisively.

Cutting off fingerprints is also a clue!

"Captain Li, you still remember the Locard Law of Material Exchange, right?"

Xu Hao said slowly.

Li Jianye paused, recalled for a moment, and then his eyes lit up.

"You mean"

"Yes, the murderer has a high level of anti-detection awareness, but it is precisely because of this anti-detection awareness that fingerprints become a clue."

Xu Hao nodded.

Local Material Exchange Principle means that wherever there is contact, there will be traces left!

The murderer cut off the fingerprints and left a knife mark. What does this mean? It means that the police have lost the clue of fingerprints.

But the question is, have you ever seen a case solved by relying on the fingerprints on the deceased’s hands?

There are not many cases.

Most fingerprint clues are left by the murderer, and they are only useful from the police's perspective! In this way, the fingerprints of the deceased are useless, even for identity checking, because the authorities will not collect fingerprints of ordinary people at all these years.

"If that's the case, why does the murderer care so much about the other person's fingerprints?"

"He doesn't know the conditions for fingerprint registration?"

"No, he is a thief, a thief, a professional criminal. He knows fingerprint entry better than anyone else, and that's why he erased the fingerprints."

"in other words."

Xu Hao paused and said, "The fingerprints of the deceased can be found in the internal system!"

"The murderer knew that finding fingerprints would directly expose him, so he erased them!"

Ordinary people wouldn't do useless things during the killing time.

You killed someone.

Now, use detergent and water to clean the traces in front of you.

Your goal is to make the scene clean, so where would you put your efforts? The tiles that were not splashed with blood and were already clean? Or the tiles that were covered with blood!? Of course, the latter.

The more the murderer fears something, the more he will hide it, and what he hides is exactly what the police need most!

The same is true for the fundamental reason for dumping the body. The hidden body is what the police want to find most.

What if fingerprints are useless, or if fingerprints are part of the target of the murder? It's the same, but it's just a different way of thinking.

The more the other party cares about fingerprints, the more the deceased Zhao Qiao must have done something to the deceased! "The source of fingerprints in the police internal system"

Looking at the expressions of the police around him, Xu Hao paused and said slowly: "Is there no need for me to say more, everyone?"

How do police internal fingerprint databases collect fingerprints? Of course, fingerprint scanners are used.

If your ID card is expired or lost, go to the police station to apply for a new one, and then the police will ask you to enter your fingerprints on the scanner.

After that, your fingerprint will be used in customs, verification information and other processes when you go abroad.

but!

However, this was the situation in the previous life, when technology was advanced! In this life, in 2003, let’s put it this way.

Currently, when the police are investigating cases and comparing fingerprints, they rely on the naked eye to distinguish them.

That's right, the fine fingerprints are not made by machines, but printed out, or directly displayed as pictures on the computer, and then observed with the naked eye! Fingerprints are entered into ID cards? I have never heard of it, so the fingerprints of most residents are not in the fingerprint database.

The idea of ​​entering fingerprints into ID cards was not proposed until 2012 and only began to appear in 2013.

And now in the fingerprint database, 99% of the fingerprints come from "criminals."

Xu Hao opened his mouth slowly and uttered two words.

"The source of the fingerprint database is criminals."

"He's a thief and a murderer"

"As long as these people break the law for the second time, the police can extract their fingerprints and identify them immediately!"

That’s right, the source of fingerprints in fingerprint databases these days is criminals.

"Check Zhao Qiao's criminal history."

"There are no fingerprints at the scene, and the fingerprint database cannot be retrieved."

“Try to get it from the court.”

The facial features database had not been established in 2003, so the murderer’s facial features could not necessarily be identified.

But... then again.

Nowadays, people compare criminals' fingerprints with their naked eyes!

Everyone has a keen eye!

As long as we give them a direction and a clue, they will be able to do the job physically without any problems.

"check!"

At the command.

Everyone took action immediately.

December 4th.

Noon, eleven thirty.

As Xu Hao's order was issued, all criminal police in Linlan City, and even police officers from the police station, were mobilized.

Zhao Qiao's facial features were examined one by one.

The criminal file has compiled countless criminal records of people named Zhao Qiao in the background.

Until "News!"

"We connected with the court and went through their archives, and eventually, we found a gang case from six years ago."

"The name of the deceased, Zhao Qiao, appeared in the case, and his identity was confirmed by comparing his photos."

"The identities of the other deceased were also confirmed after comparison."

"It's the same group of people!"

Eleven forty.

It makes one feel refreshed just by listening to it. Strictly speaking, it is the first good news.

It also makes people a little confused.

Three victims became three criminals!

The changes in the case are jaw-dropping.

Countless questions flashed through Xu Hao's mind.

At the first crime scene, the deceased was thrown into a pot of boiling oil. At the second crime scene, the minced meat became nutrients for the vegetable garden and was greedily absorbed by the farmers.

At the third scene, the murderer let the other party feel the passing of death, frozen into ice sculptures. The three dead people had an inexplicable officialdom flavor and the dead people's superb lock-picking ability, which could be called professional murderers. What happened? ? At present, the conflict between the two was caused by their profession and personality.

But he puts on airs. Who is the murderer?

If it was just an ordinary security guard, it would be fine. But if it was really... Thinking of this, Xu Hao's heart sank. He raised his head, looked at Qian Hua, and said solemnly:

"Three dead."

"What is your identity?!"
