He Ma grinned: "Isn't this kind of a clear card? This kind of thing has always existed."
"It will continue to exist in the future." Shiratori glanced at Kazuma meaningfully, "Unless you..."
Kazuma interrupted Shiratori's words: "Then, do you have any additional solutions for this case? Just like the one you recommended to me yesterday."
"You have to know that in our Japanese courts, if there is a conflict between the actual evidence and the criminal's confession, the guilty plea will win. I'm not saying absolutely, but I have been a criminal policeman for so many years, and I have never seen actual evidence win."
Kazuma nodded, signaling Shiratori to continue talking.
Shiratori continued: "But we can determine who the real culprit is through on-site investigation. Japan has also introduced a lot of the latest criminal investigation technology. It seems that in addition to traditional items such as fingerprints and blood types, they have a new, definitely not The wrong item will be used to determine the identity."
Kazuma looked at the calendar on the wall of the residential house next door, confirmed the current year, month, and day, and then directly said the original version of the Guanzi sold by Shiratori: "Is it DNA?"
"That's right! It is said that this is a more accurate detection method than blood type matching and acne spot matching. As long as a little bit of dandruff is extracted, the prisoner can be identified."
Martha: "Actually, this may not be easy to use now."
"What may not be easy to use?" Shiratori didn't turn around all of a sudden, looking at Kazuma suspiciously.
"I said DNA testing. This testing is different from ordinary testing. You need to carry out DNA matching. First of all, build a database covering the whole country, and these databases are all interconnected. Now this alone can't 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 are still using magnetic tape to record audio.
Because magnetic tape is the most reliable, most accessible, and largest-capacity medium in this era.
Therefore, in this era, it is impossible to establish a gene bank like later. After extracting the genes in dandruff, comparing the gene bank to determine the identity immediately.
In fact, at least in the era of traveling back with horses, humans did not establish a universal gene pool, but only recorded the genes of prisoners with repeated convictions.
Gene comparison still mainly relies on collecting the suspect's body samples, such as hair, and then comparing them with the genes extracted at the scene.
The premise of using genetic comparison is that the police first identify a few suspects, and it cannot play the role of finding a needle in a haystack to find the suspect.
Explaining to Ma Yitong, Shiratori frowned: "That means nothing has changed! I thought that with this genetic technology, I could throw evidence into the machine, print out the list of suspects, and get out of the machine." Spit it out."
The forensic officer in the forensic department next to him smiled and said, "Then it's better to go to Doraemon."
Shiratori raised his eyebrows: "Recently, why does the forensic department feel that there are more people watching Doraemon?"
He Ma: "I grew up watching Doraemon, what's the matter with Doraemon as an example? Don't you think about the meme of the Oolong Police Station all day long?"
"Oolong police station? My son seems to have seen it when he was in junior high school. Do you think I read this kind of low-minded person?" Shiratori asked back.
It was only then that Kazuma realized that he had overestimated "Oolong Police Station". Because of his ancient style of painting, he thought it was an early work, but in fact, even Osamu Tezuka's iron-armed Astro Boy had a style of painting in 1985. Every year is considered a novelty, and it has only been around for more than ten years.
However, works with the painting style of "Fist of the North Star" and "Saint Seiya" are now cutting-edge.
This is the unique space-time dislocation of people from the future.
He Ma: "Let's not talk about that, let's talk about just now..."
"There's nothing to say just now? Investigate the scene, find the real culprit, and then..." Shiratori turned around, blocked the eyes of others with his body, and gestured to Kazuma to wipe his neck.
He Ma: "How do you feel, Senior Shiratori, that you have been persuading me..."
"It's not an illusion, I'm just doing this. If you don't want to do this, then either join forces with others, or become a pure white knight who is annoying wherever you go." Shiratori said to a horse, "By the way, Amao Jun will probably become a hated person soon. Because the profession of lawyers is much grayer than ours."
Kazuma ignored Shiratori's last two words, and he carefully observed the whole scene.
Japan's homicide investigation attaches great importance to the murder weapon, to the point of abnormality.
This can be felt by reading Japanese detective novels and even Conan.
The reason why the prisoners in Conan often make fuss about the murder weapon, and even come up with such things as a thousand ways to kill with fishing line and a thousand ways to kill with piano line is because Japan attaches too much importance to this in solving crimes.
In contrast, China's criminal law directly stipulates that as long as other evidence is convincing and mutually corroborated, there is no need to find the murder weapon.
The reason for this regulation is that "the murderer is likely to hide or even destroy the murder weapon so that it cannot be found." This reason is very convincing at first glance.
But Japan can't do it. Japan must have a murder weapon. If there is no murder weapon, the only thing is to let the suspect plead guilty and sign the interrogation record.
He Ma tried to find clues of other murder tools at the scene.
As long as the murder weapon can be determined, it is possible to send the real murderer to the dock of the court and make him plead guilty and serve the law.
However, a criminal policeman from Section 1 broke through the blockade and rushed in to report: "Someone has surrendered, and he is a low-level member of the Fuqing Gang."
Shiratori snapped his fingers, looked at Kazuma: "I bet this person is the real culprit."
Another man in a windbreaker from the first class nodded and said, "But the gun in this person's hand must have the same bullet pattern as the bullet that hit the victim's head."
Bullet pattern is the spiral pattern left on the bullet when a rifled firearm fires the bullet.
This is actually left by the spiral pattern in the barrel.
Because all firearms wear with use, and the wear is not fixed, so the firearms that are used frequently will leave a unique spiral pattern.
This is also called the fingerprint of the firearm. Although this "fingerprint" can be changed by replacing the barrel with a new one, generally the bullets with the same spiral pattern are fired from the same gun by default.
One lesson, what this person means is that the person who surrendered must have brought the "murder weapon" pistol.
Several detectives from the first class waved to Shiratori together: "Let's go now, congratulations on adding another achievement."
"What's the use of adding merit, and I can't continue to be promoted." Shiratori showed a self-deprecating smile and waved goodbye to those who had learned a lesson.
He Ma: "Why do you feel that they are very polite to you? When I was in the Metropolitan Police Department, they were very cruel to me in the first class."
"First, I have no factional conflicts with them. Second, I'm about to retire." Shiratori spread his hands, "Let's see what we can find from the scene where the investigation has ended."
When Shiratori said this, the people in the forensic department were packing up their things. Hearing his words, he stood up first and said: "Shiratori Police Department, don't make it seem like we are lazy and not working. We should do the evidence collection. It's all done, and it's not because I have someone who surrendered that I started collecting things."
"Understood. By the way, collect the corpses slowly, we still have to take a look."
"Are you sure? There is no other cause of death. He has only one gunshot wound all over his body. The marks on his head were also shattered along with the back of his skull."
Another witness offered advice: "The Dum bomb violates international conventions, and one charge can be added to the sentence for a few more years."
"That's useless. He's not a murderer. More sentences will make the fallacy bigger."
The forensic officer shrugged and asked Shiratori: "When did you start to be an envoy of justice at Police Department Shiratori? It's not like you before."
"Isn't someone curious about the truth?" Shiratori pointed to Hema, and then pulled up the joints of the corpse for Hema to see, "Look, this place is cramp."
He Ma took a closer look: "Well, indeed."
"If you hit the back of the head hard, you may have cramps."
The witness who was still collecting the things said: "This is useless. There is no definite connection between the two things. The cramp may be caused by a blow to the back of the head, or it may be a side effect of the bullet shattering the brain."
Shiratori: "Then when you came in, did you see the corpse's feet twitch?"
"When we arrived, he had been dead for a long time. If his feet were twitching due to nerve irritation, they had stopped long ago. The body was hard when we arrived."
Shiratori: "The tendon dislocation you saw must have occurred before the corpse became stiff."
He Ma: "You seem to want me to think that the murderer in this case is someone else."
"..." Shiratori stopped what he was doing and turned to look at Kazuma.
Silence fell between the two of them.
Suddenly, Shiratori took off his gloves with a tug, and pulled He Ma out: "You follow me."
He Ma looked confused: "What?"
Shiratori didn't answer, and dragged him out of the cordon.
As soon as they got out of the blockade, uniformed policemen from the nearby police station took the blockade away.
Then the undertaker, who was in charge of disposing of the body, arrived.
That's right, because of the lack of forensic medicine in Japan, the body will be handed over to the undertaker after the forensics department has collected evidence.
In the future, if there is any situation, a forensic doctor will come to dissect it.
Shiratori pulled He into the car, and then drove the car silently, driving all the way.
He Ma: "Talk to me, I'm confused by this running all the way with me!"
"Hush!" Shiratori rolled his eyes at Ma, and parked the car on the side of the road along the river.
Then he handed the binoculars to Kazuma, and pointed to a painting boat on the river.
He Ma picked up the binoculars suspiciously, and saw Mr. Zhang from the Fuqing Gang at a glance.
"Wait a minute, Mr. Zhang? He's talking to..."
"The current acting president of the Kanto United, just because you cut your shirt into a vegetable, he took over."
"Wait, is the Fushou Gang going to shake hands with the Kanto Union?"
"How is that possible, but you think, a gangster from the Kanto Union died, and then a gangster from the Fushou Gang came to take the blame, and then the big guys on both sides had a drink and chat on the boat, don't you think there is something wrong with it?"
He Ma: "Well... It's a bit of a coincidence. But I don't think you told me everything. You actually know who the prisoner is, right?"
"Yes." Shiratori nodded, "The current acting head of the Kanto Union on the ship has a beloved young master, and then the young master committed a crime."
"Then let him squat for a few years, as long as he finds a barrister, it will turn into negligent death in minutes."
"That young master, he was just elected to the Tokyo Metropolitan Council, the same term as your Nanjo."
He said "oh" with the horse.
Shiratori continued to read Sui Sui: "The son of Ji Dao has started to enter politics, isn't this the same as that "Once Upon a Time in America"?"
In the past in the United States, the underworld leader relied on street lamp pendants to suppress and beat workers once, and got online with the federal department. Then he sacrificed his brothers, "died" himself, and suddenly became a high-ranking federal official.
He Ma: "So, you plan to let me kill this extremely young master? Can't you expose this?"
"Do you have proof?"
Hema hesitated for a while, but in the end he didn't say "you can't prove what you said".
He still wants to believe Shiratori.
At this moment, Shiratori lit a cigarette, took a deep puff, and exhaled a smoke ring, then raised his head and looked at the painting boat slowly advancing on the river: "My dream in life has almost come true. There is only a little left.
"My life, there are too many gray parts, I don't know when I was abandoned by those big figures in the struggle, and I ended up being dragged into the interrogation room of the Tokyo Metropolitan Police.
"It was hard for me to support my two children through college, graduate school, and let them enter big companies.
"They are different from me, not my lifelong police department! They have gone to college, they don't have a glass sky dome. My Shiratori family is half Chinese from now on. My children are still looking for jobs Design a crest."
Kazuma looked at Shiratori silently.
Shiratori took another puff of cigarette irritably, and continued: "The only thing I worry about now is that I will be regarded as an outcast in the strife of those big shots, you know? Both children will be affected."
He Ma: "What does that have to do with you inducing me to be an extrajudicial sanctioner?"
"Because then you will make trouble for the big shots, and I will be your weight, understand?" Shiratori put the cigarette in his mouth, and slapped his chest with both free hands, "I just want to retire safely, is there something wrong? You get what you want, and I get what I want, hello, hello!"
Kazuma looked at Shiratori, and he always felt that Shiratori still had something to say.
However, the logic of Shiratori's remarks is smooth.
He Ma thought seriously for a few seconds, then shook his head: "No, I will not punish this young master. Because the one who died was a bad guy, and the one who went to prison is also a bad guy. However, I will trip him up a bit."
Refers to bugging, and tapping phone calls.
Shiratori made a cheering gesture: "Okay, the extrajudicial judge has made his own ruling, so I won't say anything."
"No, I..."
He Ma's words were interrupted by Shiratori: "No, this is the verdict. Remember, whether you decide to let someone go or sanction him, you are exercising your authority as a judge. 'Judge' Sang."
