It took Lu Chuan longer to process the bloody fingerprints. It took more than an hour to restore the original fingerprint, but the texture was still unclear, and it was still difficult to mark feature points.
After that, Lu Chuan successively used the gradient method, operators, high-pass filtering, mask matching method, statistical difference method, etc. to enhance the image, and finally obtained a fingerprint that could be marked with feature points.
After this operation, the people behind Lu Chuan were dumbfounded. It wasn't until the fingerprint comparison success prompt sounded, specially prepared for the fingerprint battle, that everyone came back to their senses.
Won again! Moreover, it is another murder case! Sun Miao, who was smoking with Lu Chuan outside the building just now, is a criminal police officer from the High Speed Rail New District Criminal Police Brigade.
Originally, Sun Miao was a front-line criminal police officer. Because of his talent in fingerprint identification and analysis, he served as a spot investigation and fingerprint identification detective in the criminal police brigade.
Four years ago, an extremely bad home invasion and robbery case occurred in the High-speed Railway New Area. The head of the household was an old man living alone. He was hacked to death by the murderer with a kitchen knife from the deceased's kitchen.
Sun Miao went to investigate the crime scene at that time, and the only bloody fingerprint was also collected by Sun Miao.
Therefore, Sun Miao was very excited when she saw that Lu Chuan had chosen a case in their jurisdiction.
While he was excited, he also knew how difficult it was to identify and analyze this blood fingerprint. Not to mention him, this bloody fingerprint was entered into the fingerprint database of the provincial department in the second year after the incident. No one could match it twice in a row.
Sun Miao didn't know how many masters of fingerprint identification and analysis there were in the province, but those organized by the provincial department must be expert elites.
Those dispatched by the Haizhou City Public Security Bureau in previous years could only finish tied for last place. In Sun Miao's eyes, Liu Guodong's level is already the ceiling.
However, when Liu Guodong faced this fingerprint, he didn't even try to analyze it. In his words, if you don't have to do it, it will be in vain.
Because it can't be done at all. As a result, Lu Chuan won the competition in less than two hours? Before this case of home invasion and robbery that resulted in death occurred, many home invasions occurred within the jurisdiction of the High Speed Rail New District Criminal Police Brigade.
Moreover, the breaking techniques were similar. After research and judgment, it was believed that the murderer who committed the burglary and murder must be the murderer of those burglaries.
The key point between so-called burglary and burglary is not the murderer. It depends on whether there is anyone at home.
No one calls it a burglary, and someone calls it a burglary. Of course, there are also special circumstances. For example, if someone is at home but is asleep and does not have a direct conflict with the thief, this is also a burglary.
Pulling away the colleagues blocking the way, Sun Miao struggled to get behind Lu Chuan.
"Let me see! Let me see!" Compared to others, Sun Miao was more looking forward to knowing who the murderer was. On the screen, behind a few bright red characters, was the identification and analysis report.
"Hu Yong?" Sun Miao's voice rose an octave!
"This is impossible!" Lu Chuan twisted his stiff neck and turned to look at Sun Miao. Well, those from the High Speed Rail New Area must be familiar with this case.
"What is this Hu Yong...about again?" Sun Miao came to her senses and explained to Lu Chuan: "Hu Yong was the neighbor of the deceased and the reporter at the time!" The reporter... was the thief's cry to catch the thief.
Before comparing the fingerprints, Lu Chuan did not read the case file carefully and just studied the fingerprints. Therefore, it is not clear that the investigators at the time identified the murderer as a mobile criminal.
The direction has deviated. No wonder the case cannot be solved and the suspect cannot be arrested. A lot can be accomplished in two hours.
No. 72 Cuiping Road, Sunshine Happy Low-rent Housing Community. Building 2, Unit 3, Room 1008. A large group of heavily armed detectives were currently escorting a middle-aged man wearing only shorts.
The man looked stunned and was forced to lie down and put it on.
"What is your name?"
"Li Zhi."
"Do you know why you were arrested?" Li Zhi, who was being held in custody, looked pale.
"I don't know, I didn't break the law, I'm just a janitor."
"Yeah, what are you doing! Why are you arresting my old man?" Li Zhi's wife looked at the many police officers in horror, wondering what her husband had done, and so many people came.
"It's not illegal? Humph! Have you forgotten about the Cultural Park seven years ago?" Cultural Park? Li Zhi's face became even paler, and some of his resistance strength suddenly declined.
"You guys... we still came..." Li Zhi was a cleaner in the Cultural Park area back then, but it was not his time to go to work when the crime occurred.
But even so, Li Zhi was also the key target of the investigation that year. However, as the only evidence, the half fingerprint could never be successfully compared and the suspect could not be identified.
The reason why Li Zhi finally escaped from the investigative sight was because his wife testified that Li Zhi was at home when the crime occurred.
Now it seems that Li Zhi's wife has obviously given false testimony. Giving false evidence to cover up the crime: "Take Zhang Guiqin away with you." Zhang Guiqin, Li Zhi's wife.
Sunshine Happy Community is a low-rent housing community that was just built and put into use five years ago. In order to accommodate more people, the building is designed as a tube building, with more than twenty households in one unit.
Most of the people who moved here with Li Zhi were cleaners or former neighbors. Compared with ordinary commercial and residential buildings, the relationship between neighbors in low-rent housing is closer.
At this moment, the door of almost every house was open, and dozens of people were watching.
"Has Lao Litou committed a crime?"
"I don't know, it seems to be a murder case!"
"Kill someone? Old Li Tou? Stop talking about it. Old Li Tou is famous for his honesty. He wouldn't even dare to kill a chicken, but he still kills people?" A person cannot be judged by his appearance, and the sea water cannot be measured.
On the car back to the bureau, Zhang Guiqin explained everything.
"My son is going to college... I really can't help it. Lao Li didn't kill her on purpose. Really... wu wu wu... we didn't mean it..." Wang Kai sighed deeply.
Looking at Zhang Guiqin and Li Zhi: "You want your children to go to school, so you can rob others and then kill others?"
"Then do you know that the person you killed was just one month pregnant!" No one has the right to deprive others of their lives for any reason.
The current student aid system is very sound. Li Zhi's children can apply for student loans when they go to college, and there will be no problem in completing their studies.
And the lack of money Zhang Guiqin mentioned was not for her son's tuition. At that time, it was the most popular love-crazy mobile phone.
When it first started selling, a mobile phone cost tens of thousands of yuan. Li Zhi's son wanted an Ai Feng mobile phone, but he said that he would be looked down upon in college even if he didn't have this phone.
This is the follow-up.
"You...just wait for legal sanctions!" Wang Kai has been keeping a close eye on this case because of the special circumstances of the deceased.
Whenever there is a chance, take out this case and study it. At that time, the investigation of the case was very detailed.
The pregnancy of the deceased was discovered during the forensic autopsy. In fact, neither the deceased nor his family knew.
Otherwise, it would be even more painful for the deceased when he was killed. After exhaling a long breath, Wang Kai leaned back on the chair tiredly.
The simple inquiry just now seemed to take all the energy out of Wang Kai. As a police officer, you will inevitably come into contact with all kinds of dark sides of society.
Some suspects' criminal motives are simply incomprehensible. For example, Li Zhi’s motive for robbing and killing was just to buy a mobile phone for his son!
a cell phone! One corpse, two lives! He...damn it! Ding! The text message alert sounded on his cell phone, and Wang Kai subconsciously took out his cell phone.
It doesn't matter, Wang Kai's relaxed spirit became tense again!
