Detectives of Detective World

"82.7%, 86.3%, 85.6%."

When the facial skeletons of the three boys overlapped with the facial skeletons of the three men, the three people in front of the computer also saw the ironclad news.

Although the bone contrast did not reach more than 95%, the four teenagers and girls in the photo matched all the four people involved in this case, which basically confirmed that the four people in the photo were what they looked like when they were young.

"Sure enough, as we guessed, Ritsuko Jiuqi has known Yakushi Temple and Kawada Kouta, two drug dealers, since childhood."

Looking at the contrast ratio of bones on the computer, Koshisui Nanatsuki couldn't help but say.

"But Kouta Kawada and Yakushiji are both from Kyoto, but Ritsuko Jiuqi is from Kanagawa Prefecture, and the junior high school and high school are completely different."

Tang Ze recalled the information of several people and said: "The 33-year-old Kakuda Police Department was 15 years old, he was older than the other three, and he was from Shimane.

There is no connection with Jiuqi Ritsuko, Yakushiji Temple and Kawada Kouta. "

"But if this boy is really the Kakuda Police Department, it means that we have found the truth of something, right?" Koshimizu Nanatsuki looked at the photo and said.

"Of those four, two are now dead, and two of them are fugitives."

Tang Ze pondered: "Judging from the hidden relationship between the two, maybe Jiuqi Ritsuko will have contact with Yakushi Temple."

"But where should we start to find each other?" Koshimizu Nanatsu frowned, "Just knowing the relationship between them can't be of any help to their hiding place now."

"Saito, convene the staff, it's time to get busy." Tang Ze looked at Saito Bo and said, "I need you to thoroughly verify this evidence!"

"clear."

With a serious face, Saito Hiroshi immediately summoned his elite soldiers to come here, and began to investigate the evidence brought by the two Tang Ze.

Some people may wonder, just found a photo from an envelope, and the identities of the four teenagers and girls above have been confirmed. What else is there to investigate.

But if you just think that way, you're wrong, because in the eyes of researchers, there's still a lot they haven't investigated.

Because Tang Ze was a scientific researcher, he was very careful when handling the evidence. After discovering it, he immediately put the envelope and photos into the sealed evidence bag.

Because of this, even the envelopes and photo surfaces remain intact.

And this caution also gave Tang Ze feedback.

Under the investigation of the technicians, they found some dirt inside the envelope and on the surface of the photo.

This soil is very little, even more like floating ash.

But only this is enough, and some information can be obtained according to the ingredients. As for whether this information is useful or not, it depends on the follow-up investigation.

In addition to this, after careful inspection, they found a tiny dark brown spot on the back of this photo.

Although it had already turned black, the technician identified it and determined that the little black spot was the bloodstain after it had dried up and turned black.

Bloodstains were found in the photos when they were young, and this alone made Tang Ze and Yueshui Nanatsuki have a lot of associations.

In addition to the analysis of soil and blood, there is also an analysis of the nature of the photo.

After handing it over to technicians in related fields, it was determined that the two photosensitive papers found in the homes of Ritsuko Jiuki and Kawada Kouta were both of the same brand and developed at the same time.

The date stamped on the back of the photo can also be side evidence.

However, since 18 years have passed, it will be necessary to conduct a more detailed investigation to see if other clues can be found.

When the investigation of the photo itself is completed, the content of the photo is also the direction of the key investigation.

Of course, the protagonists of this investigation are no longer four teenagers, but the background of the photo itself.

Among the four, only the drug dealer Yakushiji and Kawada Kyouta came from the same place, as if they were related.

Ritsuko Jiuki, who became a criminal, came from different places.

But they got together and took this group photo. There is a natural reason why four children from all over the world met 18 years ago, and finally took this photo.

Finding the place where the photo was taken is not an easy task. Tang Ze and Koshimizu Nanatsu gathered behind Saito Hiro's computer and looked at the clear photo scanned by the other party.

"The shadow here is very short, which means that the photo was taken at noon, right?"

Looking at the shadows under the feet of the four children, Tang Ze pointed and said, "The date on the back of the photo shows that it was in early July, and it was almost the summer solstice at that time."

"You mean the angle of the shadow locks the latitude?" Saito Hiroshi immediately understood the meaning hidden in the words: "You are really enough to find me a job."

"At least I didn't leave you the most troublesome job." Tang Ze smiled and sat beside the computer next to him and said, "Pass the photo to us both."

"What are you doing?" Saito Hiro said differently.

"Isn't there a ridgeline of a mountain behind this photo?"

Tang Ze clicked on the photo and clicked on the mountain peak under the sky: "We plan to compare the ridgelines of mountain peaks across the country in the database to see if we can find a specific group photo location for the four children."

"Crazy."

Saito Hiro no longer complained about his troublesome work, he looked at the two people next to him in horror: "Do you know how long it will take to compare?

Moreover, the ridges in the photos are from 18 years ago, so there may be errors with the current database.

But at that time, it is impossible for you to rely on machines, but to compare them one by one with the naked eye. "

"There's no way out now, is it?"

Tang Ze shrugged and said, "There is no shortage of the two of us in the large troop that searched. We might as well find a way to figure out the connection between them, and maybe we can find some useful information."

To be honest, Tang Ze also investigated this case very embarrassingly. The murder case is very clear, but the murderer is running around all over the street.

It's like fighting wits and courage Tang Ze can still play to his strengths, but finding people in a haystack is not what he is good at.

So I simply hand over the work of arresting people to the army temporarily, and I restore the truth here, and maybe I will be able to gain something at that time.

With Tang Ze taking the lead in working overtime, the entire Research Institute, like a fully functioning machine, began to investigate suspicious points in all directions.

The scientific test is boring and long. Many people are late at night, so they simply sleep here.

The screening work of the two was not as heavy as imagined. After all, the machine initially screened the gaps in the ridges, but it was not too easy, because there were also many similar ridges.

The two of them were busy all night, and they finally checked a part of it, and the rest were those that were extremely similar.

At this point in the investigation, even Tang Ze can't do any further screening. After all, the ridgeline is just a sketched line. Unless you go to the field for investigation, you won't even think about finding out the answer.

"I hope what we've done will be useful." After stretching, Koshisui Nanatsuki said while moving his body.

"Let's rest and see if other people's investigations can help us make further gains tomorrow." Tang Ze got up and left, and the two went to their respective dormitories to rest.

Silent all night.

Early the next morning, before everyone had time to eat breakfast, they were called by Tang Ze to the conference room to sort out the information.

The first is the black spot in the photo, it really is human blood, and the blood type is O.

And the ash-like smile particles in the envelope are really soil, and they are also clay.

From the data point of view, the composition of feldspar is more than that of quartz. From the perspective of the proportion of metal oxides, it is a clay suitable for casting red pottery.

Based on the distribution of this clay across the country, combined with the developer serial number printed on the back of the photo, it can basically be locked in Kansai.

"In addition, judge the angle of the sun from the shadow. If it is around noon, the latitude is 35 degrees south."

Saito Hiroshi added: "In this way, it should be possible to rule out most of them again.

But unfortunately, the mountains in the background are just ordinary broad-leaved forests, and it is difficult to find clues. "

"Enough is enough."

Tang Ze looked at the screening materials and said with a smile: "Of the mountains that Yueshui and I checked yesterday, only one mountain was within our scope of investigation!"

"This mountain is near Kyoto." Saito Hiroshi said: "Now we have to run a long way."

"It's okay, I will ask a reliable guy to investigate."

Tang Ze said this and looked at everyone: "Yesterday, you worked hard for you. Today, I will give you a day off. Let's go home and rest after breakfast."

Originally, Tang Ze planned to let Yueshui Qitsu also go to rest, but the other party was unwilling, so Tang Ze asked her to go back to the dormitory first, and called her if she needed to go out.

After that, Tang Ze called Hattori Heiji.

Although this guy may be in school, judging from Hattori Heiji's usual grades and the frequency of solving cases on a daily basis, it may be a normal thing for his class teacher to ask for leave to solve a case.

The phone was connected, and Hattori Heiji's hearty laughter came from the receiver: "Let me guess the purpose of your call, is there any case that needs my help to investigate?"

"Yes, you guessed right."

Tang Ze smiled and said directly: "I have a case here that needs to be investigated in the mountains near Kansai, but I can't walk away from here.

If I leave it to others, I'm not too worried, so I can only find you. "

"No problem, I have nothing to do recently." Hattori Heiji agreed immediately after hearing the words: "Then tell me about the situation of the case."

"Well, although it is estimated that your father also knows about this matter here, you still remember to keep it a secret." Tang Ze told Hattori Heiji about the general situation of the case and their findings.

"Oh, it's there, I know." Hattori Heiji said solemnly: "I will ride a motorcycle to investigate."

"Then leave it to you, and tell me as soon as possible if there is any new information." Tang Ze asked.

"Leave it to me." Hattori Heiji agreed in one go: "Don't worry, I will investigate everything clearly, you just wait for my good news."

After hanging up, Tang Ze put away the phone and waited patiently.

During this period, he was naturally not idle, but paid attention to the search operations of the search team.

But unfortunately, one is a drug dealer, and the other is a former front-line criminal. They are both skaters. They dispatched so many people to investigate, but they did not find a trace.

In Kansai, Hattori Heiji, who dumped a fake slip for his teacher, drove his motorcycle towards the West Shigara Plateau that Tang Ze said.

Although this plateau is said to be near Kyoto, it is actually very close to Osaka where Hattori Heiji is located, basically in the middle of the two cities.

The total distance between Osaka and Kyoto is only 50km. Putting it in Tang Ze’s hometown is basically the distance between the county seat and the urban area. In addition, the West Shigara Plateau is located in the middle of the two places, which is basically a distance of 25km.

In this case, driving a motorcycle would only take half an hour at most, and because of this, Tang Ze asked Hattori Heiji to investigate.

If it is too far, he might as well directly ask the local criminal Ayanokoji in Kyoto to help in the investigation.

After riding a motorcycle for less than half an hour, Heiji Hattori came to the West Shigara Plateau.

Because of the electronic version of the photo from Tang Ze, Hattori Heiji quickly compared the shape of several large stones on the ground of the mountain peak in the photo, and determined that the group photo location of the four children is here.

Because it was a working day, there were not many people here, so Hattori Heiji could easily find the person in charge.

"Master, do you know why four children from different places meet here?"

Holding the phone and showing it to the person in charge, the other person glanced at the photo and replied without hesitation: "This is very simple, early July is summer camp."

"Summer camp?" Hattori Heiji suddenly said, "So that's what happened."

"Yes, this is our local specialty."

The old man smiled and said, "At this time every year, children and students from all over the country come to participate in the summer camp.

Ah, it was really lively at that time. Children from all over the world gathered together to do various activities and make friends from all over the world.

But unfortunately, due to the impact of low birthrate in recent years, there are not as many people as before. "

"Students from all over the country?" Hattori Heiji heard the words: "Is it delivered by parents alone or is it?"

"Basically, they are enrolled in classes, but in order to let the children experience collective life, they will be broken up on purpose." The old man replied.

"Then do you have an impression of the children in the pictures I showed you?"

Hattori Heiji asked: "Or is there any information that UU Reading www.uukanshu.com can verify that these children have been here?

Like the roster from 18 years ago? "

"There is no roster, but there should be evidence for the necessary activities of our summer camp every year." The old man on the side said.

"Really? Please show me there!"

After hearing the surprise, Hattori Heiji became a little curious, not knowing what the evidence the old man said was.
