He Ma grinned: "Isn't this kind of card equivalent to a bright card? This kind of thing has always existed."

"It will continue to exist in the future." The white bird looked at Hema with a meaningful look, "Unless you..."

He Ma interrupted Shiraki: "Then, do you have any additional solution to this case? Just like the one you recommended me yesterday."

"You have to know that if there is a conflict between the actual evidence and the criminal confession, the person who confesses guilty will win. I am not saying absolutely, but I have been a detective for so many years and have never seen real evidence win."

He nodded and signaled the white bird to continue talking.

Shiraki continued: "But we can determine who the real murderer is through on-site investigation. Now Japan has also introduced a lot of the latest criminal investigation technologies. It seems that after traditional projects such as fingerprints and blood types, they have a new and absolutely no mistaken project to determine their identity."

He looked at the calendar on the wall of the house separated by a wall, confirmed the current year, month and day, and then directly mentioned the true meaning of the secret of Shiraki's sold: "Is it DNA?"

"That's right! It is said that this is a more accurate detection method than blood type adaptation and spot adaptation. As long as a little dandruff is extracted, the prisoner can be confirmed."

Masha: "Actually, this may not be easy to use now."

"What may not be useful?" The white bird did not turn around and looked at Hema with a puzzled look.

"I said DNA testing. This testing is different from general testing. If you want to match DNA, you must first establish a database covering the national population across the country, and these databases are interconnected. Now this alone cannot be done."

After all, it was 1985, and the hardware foundation of database technology had not yet been born. In this era, various scientific research institutions were still recording audio with tapes.

Because tapes are the most reliable, convenient to access and largest capacity in this era.

Therefore, it is impossible to establish a gene bank like in this era. After extracting the genes in dandruff, compare them and determine the identity immediately.

In fact, at least in the era when we traveled back with the horse, humans did not establish a universal gene bank, but just recorded the genes of prisoners who had a serious criminal record.

Gene comparison mainly relies on collecting body samples of the suspect, such as hair, and then comparing them with genes extracted on the spot.

The premise of using gene comparison is that the police first determine several suspects, which cannot help find the suspect in a haystack.

As he explained to Ma, Bai Bird frowned: "Isn't that the change? I thought that after having this genetic technology, I could throw evidence into the machine, print the list of suspects and spit it out of the machine."

The forensics officer in the forensic department next to him smiled and said, "Then it's better to go find Doraemon."

Shiraki raised his eyebrows: "Why do you feel that more people are watching Doraemon in the forensic department recently?"

Hema: "I grew up watching Doraemon since I was a child. What happened to Doraemon as an example? Don't you think of the meme of Wulong Police Station all day long?"

"Wulong Police Station? My son seemed to have seen it when he was in junior high school. Do you think I am a childlike person?" Bai Niao asked back.

Only then did Kama realize that he overestimated "Wulong Police Station". Because his painting style is ancient, he thinks it is an ancient work. But in fact, even the style of the Iron Arm Astro Bo in Osamu Tezuka was considered a new thing in 1985 and has only appeared for more than a decade.

Works with the style of "Bei Di Shen Fist" and "Saint Seiya" are now newcomers.

This is the unique time and space dislocation that is found in people from the future.

Hema: "I won't mention these things anymore, and then I will talk about what I just said..."

"There is nothing to say just now? The on-site investigation was conducted and the real murderer was found, and then..." Shiraki turned around, blocked the eyes of others with his body, and made a gesture to Hema to wipe his neck.

Hema: "Why do you feel like you have been persuading me for the last time, Senior Baibi..."

"It's not an illusion, I'm just doing this. If you don't want to do this, you'll either be in the same place or become a pure white knight who's annoying when you go there." Bai Bird said with a horse, "By the way, Amaojun will probably become a dislike for thousands of people soon. Because the lawyer industry is much grayer than ours."

He Ma ignored the last two sentences of the White Bird, and he carefully observed the entire scene.

In the investigation of murder cases in Japan, we attach great importance to the murder weapon and to the point of perverting.

This can be felt by Japanese detectives and even Conan.

Why do criminals in Conan often make a fuss about murder weapons and even create a thousand killing methods on fishing lines and a thousand killing methods on piano lines? This is because Japan attaches great importance to this when solving cases.

In contrast, China's criminal law directly stipulates that as long as other evidence is conclusive and verified by each other, there is no need to find a weapon.

The reason for this regulation is that "the murderer is likely to hide or even destroy the weapon and cannot be found." This reason is very convincing at first glance.

But Japan cannot do it. Japan must have a weapon. If the weapon is missing, the only way to make the suspect plead guilty and sign the interrogation record.

He Ma tried to find clues about other murder tools at the scene.

As long as the weapon is determined, the real murderer may be sent to the court dock and make him plead guilty and submit to the law.

However, a criminal policeman from the first lesson rushed in through the blockade line and reported: "Someone came from the head, and it was the lower-level gang member of the Fuqing Gang."

The white bird snapped his fingers and looked at Hema: "I bet on this person as the real murderer."

Another man in the windbreaker in the first lesson nodded and said, "But the bullet pattern of the fired bullet in this person's hand must be the same as the bullet pattern of the bullet that blasted into the victim's head."

The bullet pattern is a spiral pattern left on the bullet when a gun fires a bullet with an inner chamber.

This is actually left behind the spiral pattern in the barrel.

Because all guns will wear out when used, and the wear is not fixed, the frequently used guns will leave a unique spiral pattern.

This is also called the fingerprint of a gun. Although this "fingerprint" can be changed by replacing a new barrel, the bullet with the same spiral pattern is generally driven from the same gun by default.

The meaning of this person in the first lesson is that the person who surrendered must have brought the "murder weapon" pistol.

Several criminal police officers in the same class waved to Bai Bird together: "We're leaving, congratulations on adding another contribution."

"What's the use of adding achievements? You can't continue to be promoted." Shiraki showed a self-deprecating smile and said goodbye to the person who was in the lesson.

Hema: "Why do you feel that they are very polite to you? When I was in the Metropolitan Police Department, I was so fierce to me in one lesson."

"First, I have no factional conflict with them, and second, I'm about to retire." Shiragou spread his hands, "Let's see what we can find from this scene where the investigation has ended."

When Shiragou said this, the forensic department was packing things. Hearing him, he stood up and said, "Whiragou Police Department, don't say it as if we are lazy and don't work. We have done all the evidence collections. It's not because of the people who are in charge of the head."

"I know. By the way, the corpse is slowly collected first, we need to take a look."

"Are you sure? You can't find another cause of death. He only had a gunshot wound on his body. The marks on his head were broken with the back of his head."

Another forensic adviser said: "Dam violates international conventions and can sue one charge for several more years."

"That's useless. He's not the murderer. More judgments will make the fallacy bigger."

The forensic officer shrugged and asked Shiraki: "When did you start to be a messenger of justice in the White Niao Police Department? It's not like you before."

"Isn't this someone curious about the truth?" Shiraki pointed to Huma, then pulled up the joints of the body and let Huma look, "Look, this place is cramped."

He Ma took a closer look: "Well, indeed."

"If someone hits the back of the head hard, you may get cramps."

The forensic officer who was still collecting things said: "This is useless, and there is no definite connection between the two things. The cramps may be because of the hit on the back of the head, and it may be the side effects caused by the bullet breaking the brain."

Shiraki: "When you came in, did you see the corpse's feet twitching?"

"When we arrived, he had been dead for a long time. Even if his feet twitched due to nerve stimulation, they would have stopped. The bodies were hard when we arrived."

Shiraki: "The dislocation of tendons you see must have happened before the body is stiff."

Hema: "You seem to have always wanted me to think that there is someone else in the murderer of this case."

"..." Shiraki stopped the movement in his hand and turned his head to look at Hema.

Silence suddenly came between the two.

Suddenly, the white bird pulled off his gloves and walked out with his horse: "Come with me."

He Ma was confused: "What?"

Shirou didn't answer, and pulled him out of the blockade line.

As soon as they left the blockade line, the police officers in the police uniforms of the nearby police station took the blockade line away.

Then the funeral homeowner who was responsible for handling the body also arrived.

That's right, because Japan lacks forensics, after the forensic department collects evidence, the body will be handed over to the funeral operator.

If there is any situation in the future, a forensic doctor will be able to dissect it.

The white bird pulled Hema into the car, then drove the car silently, and rushed all the way.

To the horse: "Talk, I'm confused when I'm following me all the way!"

"Shh!" Bai Bird glanced at the horse and parked the roadside along the river.

Then he stuffed the telescope to Hema and pointed to a pleasure boat on the river.

He Ma Jiangxin picked up the telescope skeptically and saw Mr. Zhang from the Fuqing Gang at a glance.

"Wait a minute, Mr. Zhang? He is with..."

"The current acting president of Kanto United, just because you cut the shirt into a vegetable, he took office."

"Wait, is the Fushou Gang going to shake hands with Kanto and make peace?"

"How is that possible, but you think, Kanto joined forces with a gangster to die, and then a gangster from the Fushou Gang came to take the blame, and then the bosses on both sides drank and chatted on the pleasure boat. Don't you think there is any problem here?"

And Ma: "Well... it's a coincidence. But I don't think you told me everything. You actually know who the prisoner is right?"

"Yes." Shiraki nodded, "The current acting leader of Kanto United on the ship has a beloved young master, and then the young master is indicted."

"Then let him go and stay for a few years. Just find a lawyer and it will turn into a mistake in minutes to cause death."

"That young master, just elected as a member of the Tokyo Metropolitan Council, is in the same term as your Nanjo."

He said "Oh" with the horse.

The white bird continued to think: "Ji Dao's son has started to enter politics. Isn't this the same as "The Past of America"?"
To be continued...
