"It's really yours, and you've made a great contribution!"
Looking at the words on the white plastic bag, Karasawa patted Naoki Uye on the shoulder: "Well done, well done!"
"Hehe... Mainly because there is this convenience store near my home. I often go there to buy things, so I am more sensitive to its trademark." Naoki Uye said modestly, scratching his head.
"Don't belittle yourself. I can't even see the pictures in the video clearly. If you can notice this, it shows that your insight is very good."
Karasawa praised without hesitation: "With this information, it will be much easier for Officer Megure and others to find the residence of Kotono Togawa.
At least we can find information about her sightings, so we can always find her residence by following the clues."
"There aren't many convenience store chains, at least I haven't seen one outside of Miwa Town."
After hearing Karasawa's words, Naoki Kamei said seriously: "We should find clues soon."
"Xianyi, the autopsy report is out."
Just when everyone was delighted with this new information, Aso Minoru suddenly knocked on the door and walked in with an autopsy report and shook it: "Do you have time?"
"Tell Officer Megure this news."
After Karasawa finished explaining to Uye Naoki, he looked at Hiroshi Saito who was busy at the side and said: "I asked you to test something before, please speed it up."
"Don't worry, it's almost over. If you hadn't asked me to strengthen the avatar just now, it would have been finished." Hiroshi Saito kept his hands on his hands and didn't look back.
"Just call me when you have the result."
After Tang Zhe and the two of them finished explaining the matter, they walked towards Aso Shimi, "So what's the result?"
"It was concluded that the direct cause of death was heart failure."
Aso Minoru handed the incident report in his hand to Karasawa: "As for the cause, it was shock symptoms caused by necrotizing myositis."
"Necrotizing fasciitis (yes, both are the same disease)?" Karasawa asked strangely: "Generally speaking, this symptom is not common nowadays, right?"
No wonder Tangze said this, because usually, this is a symptom of muscle injury and infection.
Perhaps in ancient times, this was a very common disease, but in today's era when everyone has a medical kit in their home, it is really rare for people to die in this way.
After all, if people nowadays have a cut on their hand, they have to quickly use iodophor or alcohol to reduce inflammation. How could they still get this disease?
"During the autopsy, we found bite marks on the arm of the corpse." Aso Minoru flipped through the autopsy report that Karasawa had opened and revealed a photo.
It was a close-up of the forearm of the corpse, and there were obvious tooth marks on the wound. This was hardly the direct cause of death of Kotono Tobukawa.
"Can a person die just from being bitten?" Naoki Kamei, who was standing next to him, walked over and asked in surprise after finishing his phone call.
Although he was on the phone just now, he heard the conversation between the two of them, so he had this question.
"Type A-linked cocci are pathogens that invade the body from the mouth and become disseminated."
After hearing Naoki Uye's doubts, Aso Minoru explained: "This is a very critical clinical condition. If it cannot be treated in time, the patient's mortality rate can even reach 60%.
And even if effective treatment can be obtained in time, there is still a 20% mortality rate."
"So scary?" Naoki Ueijing swallowed when he heard this: "Is it possible to have such a terrible disease after just one bite?"
"The most terrifying reason for this disease is that the fascia of the human body is very widely distributed, and myositis is an infectious disease that occurs in the subcutaneous tissue and fascia, and the infection speed is very fast."
Asano explained: "After all, the fascia of the human body is a human body structure with rich blood circulation. Infection occurs through blood circulation. Do you think it is not dangerous?"
"It's really scary."
Naoki Kamei couldn't help but shudder when he heard this.
"I'm afraid he was bitten by Tachibana when he resisted when he kidnapped the hostages."
Tangze said: "After that, I was busy with the kidnapping. I just bandaged her hastily without disinfecting it, which led to her death in the interrogation room."
"Otherwise, we wouldn't be in this predicament now." Naoki Kamei sighed.
"In short, the nails, hair, and body hair of the corpse must be thoroughly investigated."
Karasawa looked at Aso and said, "When a person dies, the clue is lost, so we can only start from this aspect.
Please send the substance extracted from it to Hiroshi Saito."
"I understand." Aso nodded and said, "I will also help."
"Oh? I didn't expect you to start to develop in an all-round way?" Tang Ze raised his eyebrows and joked: "Real people don't show their faces."
"In a place like Science Search and Research, it's always good to learn a few more skills." Aso smiled and said, "Be prepared, you can still help in emergencies like this."
Seeing Aso Minoru entering the room to help, Naoki Kamei looked at Karasawa and said, "Senior, what are we going to do now?"
"Everything we can do has been done, all we have to do now is wait."
Karasawa patted Uye Naoki on the shoulder and said: "Take the time to rest. After the results of various investigations are available, there will be no time to rest."
Eleven o'clock in the evening.
The criminals who had been searching all over finally found the residence of Kotono Tobukawa.
The reason why we were able to find clues at such a late hour is thanks to Neon's 24-hour convenience store.
Because the clue Naoki Kamei found was in a convenience store, their search work could continue smoothly even in the middle of the night.
Otherwise, you can really only waste nearly half of the precious time at night.
When Karasawa and his party arrived at Togawa Kotono's residence, the room was still full of criminals searching.
Looking at it, I even want to dig deep into the ground to look for clues.
When Karasawa entered the apartment, his first feeling was that it was small, and then he felt that it was shabby.
Although the room was cleaned very clean overall, there was too little life in this room.
A bed, a computer and a small table for eating.
It seems that Togawa Kotono lives in this house just to live, and does not have any trivial matters in life other than that.
Even the refrigerator was in a shabby state.
Instant jams, ketchup, bread slices, and finished canned foods.
Below were several bottles of drinks, one of which contained light red water. It didn't look like it was for drinking, but like it was used for other purposes.
Other than that, there are no cooking ingredients at all.
"Ah...there is really no breath of life..."
Looking at the food placed in the refrigerator, Uye Naoki sighed: "It feels like I have less trouble than a grown man.
The only goldfish that had any sense of life were all dead."
"goldfish?"
Karasawa looked at the only decorated fish tank in the room. In the light red water, several goldfish corpses were floating on it.
The color looked a bit depressing, and not only did the little breath of life not appear, but it became even more gray because of it.
"Tang Zejun, have you discovered anything here?"
While Karasawa was looking at the fish tank and pondering, Officer Megure walked over with a frown on his face: "We have searched the room like a carpet, but did not find any information.
That guy Togawa Kotono really committed a premeditated crime, and he didn't leave any clues in the room.
Everything in the computer has been completely deleted. We have now applied to the operator to investigate her Internet records, but nothing has been gained except that."
"No...the harvest is huge!"
Tang Ze pointed to the fish tank on the side and then removed the bottle of reddish water from the refrigerator: "I suspect that it is not a normal water source. The reason for the light red water source is probably some kind of microorganism."
"Ah!" Naoki Ueijing immediately realized the preciousness of this bottle of water: "Could it be that...she brought this water back near the place of imprisonment!?"
"I guess there's a good chance it is."
Karasawa looked at Officer Megure and said: "We will go back immediately to analyze the water, and I will leave the Internet records of Kotono Togawa to you.
If you have any news, please contact us at any time.”
"Then please!" Officer Megure's expression also cheered up: "If the location can be narrowed down to a certain range, then the human wave tactic will be able to exert its power!"
Although no decisive clues have been found, the scope has been reduced a lot compared to the original blind search.
However, their task is still arduous.
Even if the possibility inside the city is ruled out and the search area is greatly reduced, the area in the suburbs around Miwa Town is still vast.
And compared to the convenience in the city, the environment and roads in the suburbs are a hassle.
Moreover, abandoned and desolate locations in the suburbs are also very hidden, so the so-called blanket search is actually not safe.
What's more, the outskirts of Yoneka Town are very large. If they searched the entire outskirts of the park on the map, they wouldn't be able to complete the search in less than a day.
And what can cut off half of the useless search range depends on this bottle of water!
In reasoning and solving crimes, materials are actually evidence that is easily overlooked but can often serve as decisive clues.
Just like Sherlock Holmes can identify various sources of soil, what Karasawa has to do now is to identify the unique microorganisms in the lake water to determine the source of the water!
After returning to Kesouyan, Tangze handed over the water source to other members of Kesouyan to analyze the water quality. This small task is not difficult, it just takes time and effort.
And he himself found Hiroshi Saito: "How did your analysis go?"
"The substance remaining in the nails of the deceased is the seeds of cockscomb, which mostly grow in the northern part of Miwa Town."
Hiroshi Saito glared and slid from the computer on the left to the right: "Besides, there is no special substance on the tires of the prisoner's bicycle."
"In other words, the scope can now be narrowed down to the waterside hut in the northern part of Mikka Town?"
Tang Ze nodded to indicate that he understood and then walked towards a group testing the water source: "It's not enough, it's just not enough in the north.
You speed up, analyze the microorganisms in this water source as soon as possible, and find substances that can lock the area!"
"There are results!"
At this moment, a young researcher shouted: "It's polydinoflagellates. This is definitely a microorganism that can lock regions!"
"Oh? This is a big discovery."
Hiroshi Saito on the side heard this and quickly stood up and walked over. After looking at the microorganisms under the display mirror, he smiled and said: "Karasawa Criminal, I found the last piece of the puzzle you wanted!"
"Explain it." Tang Ze said immediately without any greetings.
"Polydinoflagellates are a type of phytoplankton, but unlike generally harmless phytoplankton, polydinoflagellates produce toxins that kill fish."
Hiroshi Saito said: "You found a dead goldfish in the suspect's home, right? It was poisoned to death by polydinoflagellates."
"So what's the point?" Naoki Ueijing asked: "Why do you say it can lock regions?"
"Because in ordinary tap water, it is impossible for polydinactyl algae to reproduce abnormally like this."
Hiroshi Saito smiled and said: "I'm afraid the prisoner wanted to use fresh plankton as bait for goldfish, so he brought the lake water, but he didn't expect that the plankton contained in the water he collected was poisonous."
While Naoki Kamei was asking, Karasawa had already contacted Officer Megure and informed him of the news.
"This is really good news."
Officer Mu, the ringleader on the phone, said with excitement: "In addition, this piece of information is very credible.
We investigated her online records and found that Nobikawa Kotono had logged into a goldfish breeding website.
I’m afraid that’s where she saw the method of raising plankton and followed it.”
"If the location where the prisoner collects water is near the place of imprisonment, then our search location will be locked immediately!"
Tangze said: "Anyway, please let people go to the north to search first. We will investigate the location of the water source as soon as possible."
"I understand." Officer Memu nodded and said, "I will make arrangements immediately."
"So, what are we going to do next?" After hanging up the phone, Karasawa looked at Saito Hiroshi and asked.
"It's very simple. Investigate whether there has been any news of "red tide" in the northern waters recently."
Saito Hiroshi replied: "The occurrence of "red tide" in the sea or lake is a normal and not unusual event.
It is normal because the reason can be easily explained, but unusual because red tide can cause fish death.
There will definitely be reports to popularize this."
"I will immediately contact the relevant departments to inquire." Uekai Naoki said immediately after hearing this.
"Leave the media to me, and I'll ask Sihuayuan to mobilize contacts to help me contact and inquire."
Tang Ze nodded and said: "This is not a big or small incident. In order to avoid causing a stir, news reports will definitely carry out popular science."
After a brief division of labor, everyone began to get busy again.
And everything they did was to get closer to the hostages.
Until he is rescued!
