Human fingerprint lines are not continuous, smooth and straight, but often have interruptions, bifurcations or turning points. These breakpoints, bifurcation points and turning points are called "feature points", and for fingerprint identification in criminal cases
Said, the main comparison is these feature points.
Generally, a complete fingerprint has 50-120 characteristic points, and as long as more than 12 of them are consistent, theoretically no one among 7 billion people will leave the same fingerprint, which can be used as ironclad evidence to identify a suspect.
Therefore, a large part of the daily work of the forensics class is to search for various fingerprints at the crime scene, the blackmail letters sent by the kidnappers, and the cardboard boxes containing the letters. Naturally, the results must be compared with those collected previously in the mansion.
A certain fingerprint I received was successfully compared, and there was a major breakthrough in the case. I couldn't help but be excited.
"Who is it?" Xiaoli Yaye rushed over in one stride, also very excited.
"It's Kawai Akihiko. This fingerprint is consistent with the thumbprint extracted from the thermos cup he uses every day." The blue hat forensics personnel immediately moved away to show him. The conditions of the temporary search headquarters were simple and they used primitive manual amplification and comparison.
"The carton was wiped intentionally, and the whole box is very clean, but the suspect missed a corner. We found several incomplete fingerprints there. One of them was successfully compared, and the others should be fine."
"円西!" Oguri Kamino was also excited. The case would be much easier to handle if there were suspects. At least he would have a clue to the investigation. He glanced at the fingerprint comparison results excitedly, then suddenly turned around and rushed towards Akihiko Kawai's head.
I dug out several books of vehicle maintenance records and compared them with the blackmail letters. I also invited several subordinates to read them together and asked, "Are the threatening sentences, wording, and sentence construction habits similar to those of Akihiko Kawai?"
?”
Everyone has certain uniqueness in written and spoken expressions. For example, they like to use inversions, omit subjects or objects in consecutive sentences, and use a specific honorific that matches their level when addressing someone. These may be different from others.
, there is a long string of words behind the blackmail letter, and now when compared with the detailed vehicle maintenance records and vehicle delivery records written by Akihiko Kawai, especially the part involving Chiho Takaramuro, the expression habits of Oguri Kamino are more and more similar.
Several other detectives took a second look and felt that there was indeed a certain similarity between the two. They could feel that the writer had a habitual respect for Chiho Takaramuro, even if her last name and honorifics could be omitted in the continuous sentences.
There is no detail about the place, it is written down honestly, and if Akihiko Kawai is also one of the kidnappers, many things can be easily explained.
For example, how the kidnappers quietly hijacked the car, and how they knew Sayuri was going home at that time, etc., were all explained in an instant.
Originally, many criminal police officers suspected that the driver, Akihiko Kawai, was an accomplice. Now that there is evidence, more criminal police officers could not help but discuss excitedly. They all agreed that Akihiko Kawai was suspected of committing a major crime. He was not the mastermind but also an important accomplice.
"Wait, isn't this right?" Qingmi Ruri had already mixed up with the criminal police at some point. After listening for a moment, he couldn't help but raise a question, "If Kawai-san is an accomplice, then he still needs to secretly throw out his watch and ask for help.
?"
"Help?" The detectives looked at the female high school student who was wearing a small patterned Wu uniform and looked like she was running towards the cherry blossoms.
Qing Jian Liuli was so frightened that she shrank her head. She was still a little afraid of being scolded by an adult if she said something wrong or did something wrong. However, the matter was of great importance and related to a person's innocence. She did not dare not to say anything, so she mustered up the courage to say:
"The emergency distress signal conveyed on the watch! The watch stopped at 5:01, which is saying Mayday, Nanahara-san... Well, he sensed the ominous atmosphere, found the watch, studied it for a while, and found out
We thought you could also see this."
She was afraid of ruining Takeshi Nanabaru's character, and Takeshi Nanabahara would try to torment her again. She tried her best to be smooth, but she basically reported the important information truthfully. After her reminder, several detectives whose hometown was at the beach realized that Mayday was
The highest level of distress call signal for shipwrecks has the same nature as SOS in Morse code. Not many people know about it, but most people really don’t think that this thing can be transmitted by a watch.
The detective who didn't understand also started asking his colleagues, and for a while he thought it made sense, and began to waver in his idea of Kawai Akihiko's involvement in the kidnapping.
Seeing this, Qingjian Liuli became bolder and continued: "Now Kawai-san is in the hands of the kidnappers. It is easy for the kidnappers to get his fingerprints and even force him to write a blackmail letter. Therefore, we cannot suspect that he is an accomplice."
, if he is wrongly accused later, he will be very sad, he obviously wants to protect Sayuri."
Oguri Yaye is not a brainless detective of the barbaric faction. He was too excited just now and didn't worry about the clues. Now that he was questioned by her face to face, he didn't get angry. He actually thought about it seriously for a moment and felt that what she said made sense.
But he still stared at her and asked: "Then why did the kidnapper do this? Is it just to blame him and use him as a scapegoat? If only he came back safely or we found his body but failed to recover the ransom,
The police will still continue to pursue the case, so what are the benefits to the kidnappers?"
As he spoke, he felt that his side was more reasonable, and his expression became stern, "Also, how can you be sure that the watch he threw was not deliberately left as evidence to prove his innocence in the future? How can you be sure that he did not do it intentionally?
Lost it somewhere and want to lead the police in the wrong direction?"
"Well……"
The "staring questioning" of a senior criminal police officer was quite lethal, and the reasoning seemed to make sense. Qingjian Liuli was speechless and became afraid again. He retreated to Takeshi Shichihara, shrank behind him, and pulled
She grabbed the hem of his clothes and aggrievedly motioned to Takeshi Nanahara to stand up for her.
Takema Nanahara was rubbing his chin in deep thought. It is really difficult for people to understand why he framed Akihiko Kawai in this way. There is something very fishy about it, but it is difficult to explain at the moment.
But when his employee was questioned, he actually blocked her behind him and said with a smile: "Then how can the Oguri Police Department confirm that this is not a kidnapper who is confusing the direction of the search? If Kawai-san is really innocent, you guys are different.
If we send a large number of manpower to track him down, wouldn't the kidnapper be safer in a short period of time?"
After a pause, he didn't want to get entangled in this topic, then looked around and said with a smile, "Also, now it is confirmed to be a kidnapping case. At least Kawai-san is also one of the victims of the kidnapping case. Don't you plan to inform his family?
Is he also a human being?"
There was silence in the room for a while. Everyone was only concerned about Miss Sayuri. For a moment, they really forgot about Kawai Akihiko's family.
Oguri Yano's expression turned ugly for a moment, and he ordered directly: "Kamizono, Buta, please take a few people there to explain the situation, comfort Kawai-san's family members, and by the way, carefully check the... situation at his home."
Both sides are reasonable. There is not much use in arguing now. If we really want to confirm whether Akihiko Kawai is suspected of committing the crime, we have to wait until he comes back or his body is found. But just in case, to be safe, he still allocates part of the police force
, went to covertly search Kawai Akihiko's home overnight.
…………
Chiho Takaramuro and Tomoda Yoshikawa needed to raise funds overnight and contact familiar banks, insurance companies and jewelry stores in exchange for diamonds and gems. Takeshi Nanahara and Ruri Kiyomi stayed in the mansion for the time being, and Nakano Eri drove the car again.
They were sent home. Anyway, the kidnappers didn't care whether the family reported the crime or not. It was much easier for the police to come and go.
It was now ten o'clock. Qingmi Ruri packed her schoolbag at Takeshi Nanahara and had to go home, but she was still thinking about the case. While packing, she asked hesitantly: "Is it really possible that Kawai-san is an accomplice?
"
She felt that what Oguri Kamino said was not unreasonable. It might not be enough to completely clear away Akihiko Kawai's suspicion by just throwing a watch and asking for help. However, Takeshi Nanahara was still thinking about things and said casually: "I don't think he is. If
He really wanted to make it look like he was kidnapped together. There was no need to use such a subtle way to ask for help. That method would only be chosen when he really couldn't think of any other way and only had a ten-thousandth chance. If
He is a kidnapper, and he is really stupid. If he wants to clear himself of suspicion in the future, he can use a more obvious and easily identifiable method to call for help, such as leaving a scrawled note instead of throwing away his watch."
Qingjian Liuli felt that what he said made sense, but immediately asked strangely: "Why didn't you explain it this way before? Your previous explanation was very weak!"
Takeshi Nanabaru touched his chin and muttered: "Because I'm afraid of accidentally killing Akihiko Kawai."
Qing Jian Liuli was so shocked that she stuffed the textbook into her bag without even putting it in. She looked at him and asked in surprise: "Do you have an idea?"
Qin Yuanwu did not deny it and said casually: "It's a little bit, but not much. Let's see how we pay the ransom tomorrow. If the ransom is..."
His voice became softer and softer as he spoke. Later, when he saw that Liuli stretched his ears and couldn't hear clearly, he quickly asked: "What if it is? What do you want to say next?"
Takeshi Nanahara came back to his senses, gave her a blow to the head, and said with a smile: "I just feel a little strange, but I am not sure about many things, and I still need to prove it. Let's see the situation tomorrow, but I think both Sayuri and Akihiko Kawai are here
He's alive, that's the good news, it's okay to sleep peacefully for the time being."
"How are you sure?" Qingjian Liuli was a little anxious, "Tell me, if you don't tell me I won't be able to sleep tonight."
"I don't care if you can sleep or not!" Takeshi Nanahara is no longer in the mood for small talk at the moment. Even if the kidnapping case turns out to be what he guessed, the evidence is hard to find. He still needs to think carefully about how to deal with it and start chasing people away directly.
, "Hurry up, it's already past ten o'clock, you will ruin my reputation if you stay here, go home now!"
"Tell me, guessing is fine, I'll help you think about it together!" Qingjian Liuli didn't want to leave, her heart was so itchy, but she couldn't stand Takeshi Qihara and refused to say anything, and in the end she was kicked out.
She was so angry that she went home with a sullen expression. She casually answered a few questions from her mother before getting into her room. She didn't even take a bath before spreading out "The World's Most Beautiful Detective, Miss Liuli Moss".
"Case Collection", I first copied the name of the "Sayuri Kidnapping Case" I encountered today with the location changed, and then punched Watson Nanabahara twice, and then started to look at it in a daze.
According to the kid, Akihiko Kawai is most likely not an accomplice, but a victim of the kidnapping case, but why would the kidnappers frame him? This is not good for the kidnappers at all. Then he or they will take the ransom and run away empty-handed.
There is no way Akihiko Kawai or the murdered Akihiko Kawai can be used as a scapegoat, so why would they do such a useless thing?
Is it really just confusing the direction of the police search?
It can't be that simple...
This should be the biggest doubt in this case!
Also, what does Takeshi Nanahara mean by what he said next? What will happen if he pays the ransom tomorrow? He already has a target of suspicion? If so, who will it be?
Mrs. Chiho? Mrs. Chiho has such a good temperament, she definitely cannot be the culprit, so who could it be? Yoshikawa Tomoda has a deep friendship, and there is no reason to commit crimes. The collapse of the Taoshiro family will not benefit him at all, and the suspicion is very small.
, but Toshio Doi is a bit suspicious. His sister refused to pay for help and came back so late, but there is no evidence...
Damn it, I can’t think of it, what on earth did that kid think of?
That bitch is so bad. Not only does he change his ways all day long, he also keeps saying half-sentences. It's really annoying. I'm so nice to him, but he treats me like a human being all day long and goes to sleep by himself.
No matter if I can sleep well or not, sooner or later I will kill him with a dump truck!
