Outside the Buckingham Hotel, a whistling police car took Wang Dahu away.

Also taken away was today's bride, her husband was suspected of murder, and Song Yaoyao at least had to record a confession.

The originally grand wedding was a mess, and only Lu Chuan and the four of them sat at the venue.

Lu Chuan lit four cigarettes, distributed them to Yang Lin and the others, and took a deep breath himself.

What's more, it's the first time I've arrested someone, and now my heart is beating like a drum in my chest, and my legs are a little weak.

"Lao Lu...... How did you recognize this guy? ”

Yang Lin spit out a mouthful of eye circles and asked the common doubts of the three of them.

Twenty-eight years ago, a series of robberies and murders in a woolen mill, of course, a few people knew that this was a key registered case of the Haizhou City Public Security Bureau.

As long as there is a backlog of cases, this case will definitely bear the brunt, and several of them have heard teachers talk about it when they were in college.

Lu Chuan's index finger moved, flicked the cigarette ash, of course he couldn't say anything about the true eye, and everyone didn't believe it: "Blood mole, when Song Yaoyao asked him for money, the old man turned his head and just revealed the bloody mole behind his left ear." ”

"You dare to him with this bloody mole?"

Lu Chuan smiled bitterly: "I wasn't sure it was him at the time, after all, he looked completely different from the suspect back then." ”

The cigarette in Lu Chuan's hand was gone, and Yang Lin added another one: "There are blood moles, but they look different, I guess this guy is likely to have plastic surgery." ”

"I deceived him, and sure enough, this old gang's eyes were flustered, there must be a problem!"

This is also what Lu Chuan came up with after analyzing why the True Eye gave a 76% similarity at the beginning.

Plastic surgery, obviously, is the greatest possibility.

Then Lu Chuan continued to test with the name of Chen Jianjian, the wanted criminal of the year, and Wang Dahu really showed his flaws.

"Grass, aren't you afraid of catching the wrong one, how many of us can't turn right?"

Lu Chuan snorted: "What are you afraid of, even if we catch it wrong, it's a fact that he has a bloody mole behind his ear." ”

"There are similar characteristics to wanted suspects, so we don't call it a brawl, we call it law enforcement!"

"At most, it's too heavy, and you won't lose your police uniform."

Yang Lin was stunned for a moment, and after glancing at each other, they all stretched out their thumbs: "Brother Lu, awesome!" ”

Although Wang Dahu's figure has been blessed and his appearance has changed, his fingerprints have not changed, and the bloody mole is enough to convict.

An hour later.

Wang Dahu's fingerprints were successfully compared with those at the scene of the crime, confirming that he was the murderer.

Lu Chuan is on fire.

When I just joined the company, when I attended the wedding of my classmate's ex-girlfriend, I caught a red notice who had been absconding for 28 years.

The point is, this wanted criminal is still the groom officer of the scumbag.

The script didn't dare to act like this, and the novel wouldn't be written like this, but Lu Chuan did it.

Thursday, 1 August 2020.

Half a month has passed since the arrest of the groom at the wedding scene, and a commendation notice has been issued from above.

Lu Chuan recorded a personal third-class merit, and several other classmates all praised him.

Everyone has done it, and the credit will naturally be shared, and Lu Chuan will not eat alone from the dormitory.

In addition, Lu Chuan, Yang Lin and others all turned into regular workers ahead of schedule and officially became a people's policeman.

After half a month, Lu Chuan has adapted to the life after the time-travel, and here has a similar world background and scientific and technological development level to his previous life.

Criminal Investigation Detachment of Haizhou Public Security Bureau, Scene Investigation Office.

Lu Chuan is watering a pot of anthurium in front of the window, because of professional reasons, Lu Chuan is now a policeman in the on-site investigation room of the criminal investigation detachment.

A good day starts with fishing.

There are only four people in the on-site investigation room, one person in charge, and two who do the work, as for Lu Chuan, although he has become a regular, he is only doing miscellaneous work now.

Cleaning, serving tea and pouring water are his main business.

Mopping the floor and wiping the table as usual, and helping others make tea, Lu Chuan returned to his place and turned on the computer.

Lu Chuan likes to read crime-solving novels, and recently found a book "On the Day of the 100th Blind Date, Arrest the Blind Date" is very good, although the title of the book pulls the crotch, but the protagonist is very reckless at the beginning, and he actually arrested the girl on the blind date.

It is similar to Lu Chuan's rebirth at the beginning of the wedding scene to catch his classmate's ex-girlfriend and husband.

Bang!

The office door was violently pushed open, and Liu Guodong glanced at the clean and tidy office: "Didn't Yang Sen and Lao Bai come?" ”

Lu Chuan hurriedly got up and looked at the time: "Master, at this time, they should be on the shuttle, and they will arrive in a while." ”

Liu Guodong is the person in charge of the current investigation room, and he is also the master who brought Lu Chuan, and his eyes were a little anxious at the moment: "It's too late, there is a scene, you come with me." ”

Lu Chuan hurriedly stood up, and the days of touching the fish came to an end: "Yes, Master!" ”

Carrying the current survey box, Lu Chuan followed Liu Guodong and trotted out of the office.

No. 38 Youyi Road.

The scene has been cordoned off by the police of the police station, and the location of the crime is a residential building in an old community, and many residents gather outside the cordon to watch the excitement.

Liu Guodong and Lu Chuan came with the large force of the criminal investigation detachment and went directly to the scene.

"Lao Liu, you do the survey first."

In the case of a homicide, the detachment immediately activated the homicide detection mechanism, and Qin Yong, the leader of the criminal investigation detachment, was the first commander at the scene.

Liu Guodong is a veteran criminal policeman of the detachment, and ten years ago, according to the needs of the detailed reform of police types, he was transferred from an ordinary criminal police officer to an on-site criminal policeman.

In fact, the biggest difference between the so-called on-site investigation and general criminal police work is specialization.

The main work is crime scene photography, evidence collection, physical evidence inspection, analysis and preservation, and various trace identification.

Only in relatively large criminal investigation detachments will there be full-time criminal police officers on the spot, and in addition to on-site investigation tasks, they will not directly participate in the investigation and arrest work.

It is a combination of internal and field police services.

Liu Guodong has been doing field surveys for ten years and is extremely experienced, so he brought foot covers, masks, and gloves, and took over the field survey box in Lu Chuan's hand: "Xiao Lu, take pictures first." ”

Taking pictures is the basic skill of the survey.

At the scene of the murder, the first work to be carried out is the current investigation, followed by the forensic doctor, although the work content of the two is very different, but there is also an intersection.

Generally speaking, the current investigation pays more attention to the investigation of traces and physical evidence at the scene, such as footprints, fingerprints, and the extraction of small attachments, etc., while the forensic medical examination focuses on the time of death of the corpse and the cause of death.

After Lu Chuan received the order, he did not directly pick up the camera to shoot, but began to look around the entire crime scene.

There is a big difference between taking pictures in the case investigation and taking pictures in the general sense, there are rules and restrictions, and there is a special workflow in the field investigation major.

Lu Chuan, who has already received the primary on-site survey and photo-taking skill card, is no longer the kind of paper talk that he learned in school in his memory.

There are three levels of system reward skills, junior high school, and the primary skills are equivalent to the skill level mastered by the general backbone criminal police.

"The basic mission is released, and an excellent homicide scene photo is taken."

"The advanced task is released, and through on-site investigation, clues to solve the case are found and the task force is assisted in solving the case."

There are two types of criminal investigation system tasks, completing basic tasks is a necessary job, and completing advanced tasks will receive system rewards.

The scene of the crime was a rectangular living room with an area of about 40 square meters, and the deceased was a middle-aged man.

The corpse was lying on its back on the couch, its eyes wide open, and it looked dead.

A sharp knife that had been half-cut into the blade was plunged into the left side of the chest, and the deceased's right hand was held on the hilt, and the red blood infected his clothes, condensing into a puddle at the deceased's feet, suspected of suicide.
