Chapter 137 Found it! Disappearing fingerprints!
On the top floor, no one usually appears here, only the proprietress comes up to water the water.
But.
Now there are some strangers here.
Two corpses, one murderer!
The other party came in after breaking the lock!
Xu Hao walked to the door, picked up the lock, and looked at the marks inside with a solemn expression on his face.
"Trace of damage on it"
"It's very small, almost negligible. If it hadn't been mentioned at the first scene that the murderer would pick the lock, we only discovered it after careful inspection."
Qian Hua took a step forward and spoke in a deep voice.
The lock is the kind of lock that looks like an iron knot, and almost every household in the countryside has one at this time.
This lock is easy to pick.
But the problem is that it is not easy to pry it open without causing slight damage or even no damage!
General lock picking seems to be just a few tools, and it has no effect if the lock opens with a snap.
But in fact, there is damage.
It is mainly concentrated on the three parts of the keyhole, lock cylinder and lock body. If you pick the lock, the lock body can be ignored.
But the damage to the lock cylinder will inevitably occur as long as it is not opened with a key!
However, the murderer minimized the damage.
His technique is almost not like picking a lock, it's just like opening a lock with a normal key!
Without the careful inspection by police dogs and police, it would not have been discovered.
"Go to the murder scene."
Xu Hao glanced at the police officers who were packing the corpses and bones, shook his head and walked out.
There is very little information on the scene where the body was dumped. There are no clues or traces inside the shed, and there are none outside.
As for the murder scene
It's not far away, within ten meters of Xu Hao.
The third floor is where the Zhang family of the deceased lived.
At this time, a bunch of policemen were surrounding the place, searching everywhere inside.
There were other residents around, with expressions of fear and curiosity on their faces, and they were talking to each other.
Push through the crowd and enter the house.
There was blood everywhere!
The ground and bed exuded a strong smell of blood!
"The scene of mutilation was mainly inside the toilet, and most of the blood flowed to the sewer pipes."
"The murderer then used one or more knives to accurately dismember his body."
"According to the police's estimation, the murderer dismembered the corpse very quickly. He is like a butcher dismembering a cow. He is familiar with every part of the human skeleton and can find the most suitable and easiest angle to cut the knife!"
Qian Hua looked at this tragic scene and said in a deep voice.
"Is it a doctor?"
Li Jianye was suspicious and thinking.
There is a high probability that being familiar with the human skeleton has something to do with medicine, but the problem is.
"A doctor would not dismember the 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 with bare hands and pick the lock."
Xu Hao stood at the window and said something.
He looked out.
The wall outside the window is not stable. There is a balcony and an air conditioner, but it is not something that ordinary people can climb.
"This is a"
"A very professional murderer."
Xu Hao paused and said a very surprising word.
"Professional?" Li Jianye frowned.
"Like a killer?"
"Similar." Xu Hao said.
This is a thief.
However, this thief has extremely superb lock-picking skills!
At the same time, he can climb the third floor with bare hands, and he has the means to kill people with precision. He can dismember people far more efficiently than the average butcher who kills pigs!
He is very professional and can be called a career criminal.
Such a person
What is the conflict with the deceased?
And what did he do with the money?
From a technical point of view, the other party has this skill and is not short of money.
Is the thief short of money?
The diligent thief is actually not that short of money. The other person's skills can equal someone else's monthly income in one day.
This makes it even more unreasonable to stare at the deceased's money.
Until
"Zizi~"
"Boss, we have a clue!"
Suddenly, a slightly harsh sound came from the intercom.
Everyone paused, their eyes focused here.
"Say." Qian Hua spit out one word.
"After screening based on what Consultant Xu said, many clues came quickly from the back office."
“Eventually, we identified one.”
"The person who called the police called the police on the morning of the 1st. According to the other party, the refrigeration company had serious problems with the refrigerated food due to personal problems."
"But the other party disappeared and could not be contacted. He was suspected of absconding in fear of crime."
"Not long ago, the internal staff brought police dogs to conduct a thorough re-investigation of the alarm incident. The police dogs 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 scene of the third crime!
In less than a day, three incidents occurred!
This is simply unbelievable.
It was half past six that afternoon.
When Xu Hao and others rushed to the location mentioned by the internal staff, they saw such a scene.
A frozen man, with his arms folded across his chest, knelt on the ground, curled up, and the facial features on his face were stiff and expressionless due to hypothermia.
This is a naked corpse.
A naked corpse without even underwear!
There is ice on the surface of the body, water stains remain in the thick hair, and the fat belly begins to swell, giving 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 ladle.
"Preliminary judgment shows that the murderer killed the third deceased on the night of the 31st and 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, under the cold wave weather, the third deceased curled up due to hypothermia and fell to his knees."
"At the same time, the murderer used a water ladle. In the sub-zero temperature, he filled the water ladle with cold lake water and poured it over the head of the deceased. The cold lake water flowed from the top of the head to the entire body."
"In the end, he became an iceman."
The police officer in charge of on-site investigation said.
Linlan City belongs to the south, but it is now December, which is winter, and it is also the time when the cold wave hits!
In addition, the weather will be much colder now than in the last life, so.
After a rain, on the 1st, a cold wave hit, the temperature dropped below zero, and a person froze to death outdoors.
"During the day on the 1st, the murderer's body is most likely wrapped in a layer of ice."
The other party said again.
Xu Hao listened. He squatted down and looked at the fat body.
When I moved the two hands with my hands, I found that the tendons of both hands were severed, as were the tendons of both feet.
At the same time, the fingerprints on both hands were erased and cut with a knife.
The deceased was named Zhao Qiao, who was in his forties and worked as a cold storage guard for a refrigeration company.
But now he is dead here, frozen to death.
The murderer brought him here and cut off his hand tendons and hamstrings, incapacitating him.
Then, in a hypothermic environment, they were irrigated layer by layer with cold water.
The cold water turned into ice, covering the body surface, and the whole person seemed to have turned into a human-shaped ice sculpture!
Even now, the ice residue on the body has not completely melted away.
"Why aren't the corpses broken up in the third scene?"
After the investigation, Li Jianye wrapped his coat around himself and raised a question.
"At the first scene, the body was cut into pieces, then wrapped in egg liquid and bread crumbs, and became fried chicken."
"At the second scene, the corpses were also chopped into pieces and used as fertilizer in the vegetable field."
"At the third scene, the body is missing no parts!"
Li Jianye opened his mouth to summarize, with confusion on his face.
"Why was the body not dismembered at the third scene?"
"Instead it became an ice sculpture."
"How many of the deceased people were not offended by one thing? If not, the probability is too small."
Five acquaintances, because of different things, one person killed them
The probability is too small.
Totally negligible.
"Fried chicken, vegetable patch, ice sculpture." "Do these three locations have one thing in common?"
Qian Hua asked.
Xu Hao fell into deep thought.
The murderer obviously came with some purpose.
He is extremely targeted!
But the methods of killing are so scattered
why is that?
"Has the identity information been found?"
Xu Hao frowned and thought.
He knelt down and looked at the dead body's peaceful and steady facial features.
"The facial features of the corpse are obvious. After being refrigerated by cold air, the appearance of the corpse looks almost the same as before death."
Hearing this, the people around shook their heads, "The refrigeration company did not provide a valid contract."
"The other party said he was a cold storage custodian, but in fact he was a security guard. The company wanted him to resist."
"The clothes and identity information were taken away by the murderer."
"The internal staff searched the deceased's rental house for a while and found only traces of the murderer stealing property, but no other clues that could prove his identity were detected."
No clues again.
No clues again!
Is it so difficult to check identity information?
Li Jianye frowned and thought, but didn't wait for him to speak.
"Check fingerprints."
Xu Hao glanced at his hands and said casually.
"The fingerprints were erased." Qian Hua shook his head, "Including the layer of skin on the fingerprints, they were cut off by the murderer with a knife. This was true for all ten fingers."
“What I want is to cut off the fingerprints!”
Xu Hao said decisively.
Cut off fingerprints
Also a clue!
"Locard's law of material exchange, Captain Li, do you still remember it?"
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-reconnaissance awareness, but it is because of his anti-reconnaissance awareness that the fingerprints become clues."
Xu Hao nodded.
Lockard's law of material exchange means: Any contact must leave traces!
The murderer cut off his fingerprints and left traces of knife cuts. What does it mean?
Representatives, police lost the fingerprint clue.
But here’s the question, have you ever seen a case that was solved based on the fingerprints on the deceased’s hand?
Not many cases.
Most of the fingerprint clues are used to detect the murderer's legacy, and are only useful from the police's perspective when looking at the murderer!
From this point of view, the fingerprints of the deceased are of no use at all, even if they are checking the identity, because these days the official will not collect the fingerprints of ordinary people at all.
"In that case, why does the murderer care so much about the other person's fingerprints?"
"He doesn't know the conditions for fingerprint entry?"
"No, he is a king of thieves, a thief, and a career criminal. He knows the entry of fingerprints better than anyone else, and that is why the fingerprints were erased."
"In other words."
Xu Hao paused and said:
"The fingerprints of the deceased can be found from the internal system!"
"The murderer knew that the fingerprints found would directly expose him, so he erased them!"
Ordinary people don'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 site clean, so where will you put your efforts?
Is it for those tiles that are not splattered with blood and are already clean?
It's still a tile full of blood! ?
Naturally it is 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 essential reason for dumping corpses. The hidden corpses are what the police want to find most.
What if fingerprints are useless, or if the other party’s murder target includes fingerprints?
Same thing, but with a different way of thinking.
The more the other party cares about fingerprints, the more likely the deceased Zhao Qiao’s hands must have done something to the deceased!
"The Source of Fingerprints from Internal Police Systems"
Looking at the expressions of the police around him, Xu Hao paused and said slowly:
"Don't you need me to say more?"
How are fingerprints counted in the fingerprint database of the police's internal system?
A fingerprint scanner, naturally.
If your ID card expires or is lost, go to the police station to apply for a new one. Then the police will ask you to enter your fingerprints on the scanner.
After that, the fingerprint will be used with customs and verification information when you go abroad.
but!
However, this was the situation in the last life when technology was advanced and used!
This life, 2003.
Put it this way.
Now within the police, when comparing fingerprints in investigating cases, they rely on the naked eye to distinguish them.
That's right, those fine fingerprints are not printed mechanically, but printed out, or appear directly on the computer in the form of pictures, and then observed with the naked eye!
Fingerprint entry into ID card?
I have never heard of it, so the fingerprints of most residents are not available in the fingerprint database.
Fingerprint recording on ID cards was only proposed in 12 years and only started to appear in 13 years.
And now in the fingerprint database, 99% of the fingerprints come from
"Criminal."
Xu Hao slowly opened his mouth and said two words.
"The source of the fingerprint database is criminals."
"It's a thief and a murderer"
"As long as these people break the law a second time, the police can collect their fingerprints and lock them in immediately!"
That's right, the source of fingerprints in fingerprint databases these days is criminals.
"Check it out about Zhao Qiao's criminal experience."
"There are no fingerprints at the scene, and the fingerprint database cannot be retrieved."
"Try to get it from the court."
No facial features database was established in 2003, so the murderer's facial features may not be able to be identified.
But.
Then again.
People these days, comparing fingerprints of criminals relies on the naked eye!
The average person has a fiery eye!
As long as you give them a direction and a clue, they'll be fine if you leave things done with the body to them.
"Check!"
Give an order.
Everyone took action immediately.
December 4th.
Noon, half past eleven.
As Xu Hao's order was issued, all the criminal police in Linlan City and even the police from the police station were mobilized.
Zhao Qiao's facial features were questioned individually.
The criminal files collected countless criminal records named Zhao Qiao in the background.
Until
"News is coming!"
"We contacted the court, went through the other party's archives, and finally found a gang case from six years ago."
"The name of the deceased Zhao Qiao appeared in the case, and by comparing the photos, the identity of the deceased was confirmed."
"The remaining deceased were compared and their identities were confirmed."
"It's the same group of people!"
Eleven forty.
Listening to the sound in the ears makes people feel refreshed. Strictly speaking, it is the first sound of good news.
It's also a little confusing.
Three victims. Three criminals!
The changes in the case are shocking.
Countless questions flashed through Xu Hao's mind.
At the scene of the first crime, the deceased was thrown into the boiling oil pan
At the scene of the second crime, the minced meat became nutrients in the vegetable patch, and was absorbed by greed.
In the third scene, the murderer made the other party feel the passing of death, and the frozen ice sculpture.
The three dead people have an inexplicable smell of officialdom
And, the deceased’s extremely superb lock-picking ability could be called a professional murderer.
What happened! ?
At present, the conflicts between the two are caused by their profession and personality.
But what is the identity of the murderer? ?
It would be fine if he were an ordinary security guard, but if he really was.
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!?"
