The human fingerprint pattern is not continuous, smooth and straight, but often interrupted, bifurcated or turned, and these breaks, forks and turning points are called "feature points", and for fingerprint identification in criminal cases, it is mainly compared with these feature points.

Generally, a complete fingerprint has 50-120 characteristic points, and as long as it is determined that more than 12 of them are consistent, it is theoretically impossible for anyone in the seven billion people to 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 forensic department is to look for various fingerprints at the scene of the crime, and the extortion letters sent by the kidnappers and the cardboard boxes containing the letters must naturally be checked.

"Who is it?" The little chestnut duck Ye rushed over with one arrow step, and was also very excited.

"It's Akihiko Kawai, and this fingerprint is consistent with the thumb fingerprint extracted from the thermos cup he uses every day." The blue hat identification officer immediately gave up his position to show him, and the conditions of the temporary search headquarters were simple, using the original manual magnification and comparison method, "The carton was intentionally wiped, and the whole was very clean, but the suspect missed a corner, we found a few mutilated fingerprints there, one of which was successfully compared, and the others should be fine." ”

"Roar!" Oguri Kamano was also excited, it was much easier to handle the case with a suspect, at least he had a clue to track it down, and he excitedly glanced at the fingerprint comparison results, suddenly turned around and rushed to Kawai Akihiko's sundries, turned out a few vehicle maintenance records, car records and extortion letters, and invited several subordinates to look at them together, and asked, "Are the words and sentences used in the latter threatening sentences very similar to Kawai Akihiko?" ”

Everyone has a certain uniqueness in written and oral expression, such as liking to flip it upside down, omitting the subject or object in continuous sentences, and using a specific honorific that conforms to one's rank when addressing someone, which may be different from others, and there is a large string of words behind the blackmail letter, which is now compared with the detailed vehicle maintenance records and car records written by Akihiko Kawai on a daily basis, especially the part involving Chiho Takarato, and the more you look at the expression habits, the more similar the Oguri Kagano looks.

Several other criminal policemen followed and looked at it, and they also felt that the two really had a certain degree of similarity, and they could feel that the writer had a habitual respect for Treasure House Tochiho, and even if her surname and honorifics could be omitted in the continuous sentences, they were all omitted, and they were honestly written, and if Akihiko Kawai was also one of the kidnappers, there were many things that could be explained very well.

For example, how the kidnappers quietly hijacked the vehicle, and how they knew that Sayuri was going home at that time, etc., all had an explanation in an instant.

Originally, there were many criminal police who suspected that Akihiko Kawai was complicit in the driver, but now that there is evidence, more criminal police can't help but discuss excitedly, and they are unanimously inclined to Akihiko Kawai is suspected of committing a major crime, not the mastermind but also an important accomplice.

"Wait, isn't that right?" Kiyomi Ruri didn't know when she was already mixed in the pile of criminal police, and after listening to it for a while, she couldn't help but question, "If Kawai-san is a co-defendant, then is it necessary for him to secretly throw out his watch for help?" ”

"Help?" The criminal policemen looked at this female high school student wearing a small striped Wu costume, much like a girl running on the way to enjoy the cherry blossoms.

Kiyomi Ruri shrank her head in fright, she was still a little afraid of being scolded by adults for saying the wrong thing and doing the wrong thing, but the stakes were very high, and it was related to a person's innocence, so she didn't dare not say it, so she mustered up the courage to say: "The emergency distress signal conveyed on the watch!" The watch stopped at 5:01, saying Mayday, Nanahara-san...... Well, he sensed the ominous aura, found the watch, studied it for a while, and found this, and we thought you could see it too. ”

She was afraid of destroying the character of Qiyuan Wu, and when she turned around, Qiyuan Wu wanted to toss her again, and tried her best to be round, but she basically reported the important information truthfully, and after she reminded her, several criminal police officers in her hometown at the beach reacted, Mayday is the highest level of shipwreck call signal, and the SOS nature in Morse code, there are not many people who know, but ordinary people really can't imagine that this thing can be conveyed with a watch.

The criminal police, who didn't understand, also began to ask their colleagues, and for a while they felt that it made sense, and began to waver in the idea that Akihiko Kawai was involved in the kidnapping.

Kiyomi Ruri also became emboldened when he saw this, and continued: "Now Kawai-san is in the hands of the kidnappers, and it is easy for the kidnappers to get his fingerprints, and even force him to write a blackmail letter, so you can't suspect that he is an accomplice, if you turn around and wronged him, he will be very sad, he obviously wants to protect Sayuri." ”

Xiao Chestnut Duck Ye is not a brainless criminal policeman of the barbarian faction, he was too excited just now and he didn't give a clue at all, but now he was questioned by her face and was not angry, but he really thought about it seriously for a moment, and felt that what she said had a certain truth, but he still stared at her and asked, "Then why did the kidnappers do this?" Is it just to blame him and use him as a scapegoat? If only he comes back safely or if we find his body but we can't recover the ransom, the police will continue to pursue him, so what's the benefit of the kidnappers doing that? ”

As he spoke, he felt that his side was more reasonable, and his expression became stern, "Also, how can you be sure that he threw out the watch and didn't deliberately leave evidence for the future attempt to prove his innocence?" How can you be sure that he didn't deliberately leave it somewhere in an attempt to lead the police in the wrong direction? ”

"Uh......"

A senior criminal policeman's "staring questioning" is still quite lethal, and the reasoning seems to be a little reasonable, Kiyomi Ruri was speechless and began to be scared again, retreated to Nanahara Takeshi's side, shrank behind him, pulled the hem of his clothes, and aggrievedly motioned to Nanahara Takeshi to stand up for her.

Nanahara Takemasa touched his chin thoughtfully, it is really difficult for people to understand such a slander against Akihiko Kawai, there is a lot of catty in it, but it is difficult to explain for a while.

But his staff was asked, and he really pushed her behind him, and said with a smile: "Then how can the Oguri Police Department confirm that this is not a kidnapper confusing the direction of the search?" If Kawai-san is really innocent, but they have assigned a large number of people to follow him to track him down, wouldn't it be safer for the kidnappers in a short period of time? ”

After a pause, he didn't want to dwell on this topic, looked around again, and said with a smile, "Also, now it's confirmed that it's a kidnapping case, at least for now, Kawaga-san is also one of the victims of the kidnapping case, aren't you going to inform his family?" He's human too, right? ”

The room was silent for a while, and everyone only cared about Miss Sayuri, and for a while they really forgot about Akihiko Kawai's family.

Oguri Kamono's face was ugly for a moment, and he directly ordered: "Shangyuan, Butian, you take a few people to explain the situation, appease Kawai-san's family, and carefully check his family's ...... by the way Circumstance. ”

Both sides have some reason, it's useless to quarrel now, if you really want to determine whether Akihiko Kawai is suspected of committing a crime, you have to wait for him to come back or find his body, but just in case, he still dedicates a part of the police force to secretly search Akihiko Kawai's home overnight.

…………

Takarato Chiho and Yoshikawa Tomoda need to raise funds overnight, and contact familiar banks, insurance companies, and jewelry stores in exchange for diamonds and gemstones, Nanahara Takeshi and Kiyomi Ruri stayed in the Western-style pavilion for the time being, and Nakano Eri drove them home, anyway, the kidnappers didn't care if Treasure Muro reported the case or not, and it was much easier for the police to enter and exit.

It's ten o'clock at this time, and Kiyomi Ruri has to go home after packing her schoolbag here in Nanahara Takeshi, but she is still thinking about the case, and she hesitates and asks while cleaning up: "Is it really possible that Kawai-san is the co-defendant?" ”

She felt that what Oguri Kamono said was not unreasonable, and it might not be enough to completely wash away Akihiko Kawai by throwing a watch for help, and Nanahara Takeshi was still thinking about things, and said casually: "I don't think he is not, if he really wants to fake the illusion that he was kidnapped together, there is no need to ask for help in such a vague way, that method can only be found in the real can't think of any other way, and it will only be chosen with a 1/10,000 hope." If he is a kidnapper and is so stupid as to want to clear his name in the future, he can call for help in a more obvious and easier way to be identified, such as leaving a scribbled note and no need to throw away his watch. ”

Kiyomi Ruri felt that what he said made sense, but immediately said strangely: "Why didn't you explain that before?" Your previous explanation was very weak! ”

Nanahara Takeshi touched his chin and muttered, "Because I'm afraid that I'll accidentally kill Akihiko Kawai." ”

Kiyomi Ruri was taken aback, stuffed the textbook into the schoolbag, looked at him and wondered, "Do you have an idea?" ”

Nanahara Wu didn't deny it, and said casually: "It's a little, but it's not much, let's see how about paying the ransom tomorrow, if the ransom is ......"

The more he spoke, the quieter he became, and he couldn't hear clearly when he stretched out his ears, so he hurriedly asked, "What is it?" What do you want to say later? ”

Nanahara Takeshi came back to his senses, flicked her head, and said with a smile: "I just think it's a little strange, but there are many places I'm not sure, and I still need to prove it, let's see the situation tomorrow, but I think Sayuri and Akihiko Kawai are still alive, this is good news, it's okay to sleep peacefully for the time being." ”

"How are you sure?" Kiyomi Ruri was a little anxious, "You 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!" Qiyuan Wu was not in the mood to chat at this time, even if this kidnapping case was really as he guessed, the evidence was not easy to find, he had to think about how to deal with it, and directly started to drive people away, "Hurry up, it's past ten o'clock, if you stay here, it will ruin my reputation, go home now!" ”

"You tell me, guess it's okay, I'll help you think about it!" Kiyomi Ruri didn't want to leave, and her heart itched terribly, but she couldn't stand Nanahara Takeshi and refused to say it, and in the end she was swept away.

She was very angry, went home with a hidden fox face, casually coped with two sentences of motherly inquiries and went into her room, and spread out the "The World's No. 1 Meiji Famous Detective Miss Glass-Moss Detective Collection" without even taking a bath, first changed the name of the "Sayuri kidnapping case" encountered today and copied it in, and punched Nanahara Watson twice, and then looked at it and began to be in a daze.

According to that kid, Akihiko Kawai is most likely not an accomplice, but a victim of the kidnapping case, but why did the kidnappers frame him? This is not good for the kidnappers at all, and when he or they run away with the ransom, the empty-handed Akihiko Kawai or the killed Akihiko Kawai will not be a scapegoat at all, why should they do such useless work?

Is it really just confusing the direction of the police search?

It can't be that simple, right......

This should be the biggest doubt in this case!

Also, what does the words behind the dog thing mean by Takeshi Nanahara? What happens when the ransom is paid tomorrow? He already has a suspicion target? If so, who would it be?

Lady Chiho? Mrs. Chiho has such a good temperament, she must not be a prisoner, so who could it be? Yoshikawa Tomoda has a deep affection, and there is no reason to commit the crime, the collapse of the treasure house is not good for him at all, the suspicion is very small, but Toshio Michii is a little suspicious, his sister refuses to pay for help, and he returns it so late, but there is no evidence......

Damn, I can't think of it, what the hell did that kid think?

That dog thing is so bad, not only does he change his tricks all day long, but he also talks half-talking, he is really angry, I am obviously so good to him, he treats me as a bad person all day long, and he sleeps a lot, he doesn't care if I can sleep well or not, sooner or later he will be killed with a mud truck!
