Tokyo Police

"During this period of time, I have caused you a lot of trouble, and I am really sorry..."

As Aizawa said that, he bowed to Takashi Imai, who had been following them around for the past few days, and his colleagues in the forensics class who had done a lot of work in investigating the scene of Professor Noguchi's murder not long ago. Seeing this, Hua Xing hurriedly followed behind Aizawa-senpai to salute everyone.

"If it's there, it's really a pity. In the end, I couldn't find the real murderer of Professor Noguchi. It's really a pity!"

Kanai Takashi also hurriedly saluted Aizawa and Hanagata. Since the end of the second investigation of the scene of Professor Noguchi's killing that day, Aizawa and others have disclosed the news of their imminent departure to Hokkaido. Because the results of the second investigation showed that the scene where Professor Noguchi was killed had been destroyed and even a complete fingerprint could not be collected. Aizawa and Kagata naturally no longer need to stay here.

"Hey, I'm really ashamed to say it. I've been in forensics for so many years, and this is the first time I've encountered such a clean scene. I blame the murderer for being too cautious. In order to sabotage our investigation, the scene was destroyed. Cleaned up as it is now."

The person in charge of the forensics class also felt very regretful. Although he had tried his best, he still failed.

"There's nothing we can do about it. Who made us one step behind the murderer! However, before I leave, there is actually one more thing I want to pass on to you!"

At the end of the sentence, Aizawa suddenly took out a business card placed in a plastic bag from his pocket and handed it to the person in charge of the Hokkaido Forensics Division who came to see him off. After the other party took the business card handed by Aizawa, he was very curious and took it in front of him and looked at it carefully.

"Asuda Housekeeping Office, President Asuda Naoto? What does this mean?"

The other party carefully looked at the front and back of this business card, and then asked Aizawa with some doubts.

"The person on the business card is the real murderer we suspect to have killed Eiji Noguchi so far! There are fingerprints left by the other party on the business card. If there is no damage to the scene, we can use this business card to find direct evidence of the other party's murder. Hey, it would be great if the suspect's accomplice missed something, even if only half a fingerprint was found, it would be enough for us to convict the suspect..."

Aizawa sighed deeply and fell into silence immediately, but after a while, Aizawa questioned his colleagues in the forensics class with some reluctance.

"I remember at the beginning, didn't the police suspect that Professor Eiji Noguchi committed suicide by burning charcoal, so is the charcoal pot found at the scene still in the hands of the police?"

As soon as Aizawa said this, the colleagues in the Forensic Division of the Hokkaido Prefectural Police Headquarters who were still downcast suddenly raised their heads and said with joy:

"Hey, we do still keep this charcoal basin, because it is an important evidence related to the cause of death of the deceased. It seems that the charcoal basin is now in our evidence storage room!"

"So, what material is this charcoal basin made of? Is it possible that we can find the fingerprints left by the suspect at the scene from it?"

"I remember that the charcoal basin is made of metal. Although it is a little difficult, if there are fingerprints of the suspect on it, we have a way to get it."

The person in charge of the forensics class said to Aizawa Kazuyata with great certainty.

"Well, is it really possible to get the suspect's fingerprints? That thing has been roasted by the charcoal fire on the spot. Can the fingerprints be obtained by technical means under this circumstance?"

Kanai Takashi asked the seniors of the forensics class in disbelief. As for the general principle of fingerprint collection, Takahashi Kanai knows a little bit. The principle is mainly based on the distribution of salt and protein on the finger, using chemical reactions to display these traces under fluorescence. However, because the surface of the material is metal, and it has been roasted at a high temperature enough to denature proteins, Takazhi Imai has long given up hope for those fingerprints on the surface of the charcoal pot.

"Hey, most people think that the high temperature will automatically make the fingerprints left on the scene disappear. However, with the current technology, it is not impossible to collect similar fingerprints. If a small amount of special means is used, There is still hope that the fingerprints will be successfully reproduced.”

Because of Aizawa's unintentional remarks, the investigation work, which had already been exhausted, had renewed hope, and almost everyone present was looking forward to the next good news.

"I didn't expect it! I didn't expect to see new investigative clues before I left. But it's a pity, we have already booked a flight back to Tokyo, and at the same time, the Forest Police Department has also made new work arrangements. ."

"It's such a pity, can't we wait a few more days? After all, we'll have to wait until we get the results and go back to Tokyo!"

"I'm sorry, although we also want to stay and wait for your results, but the Metropolitan Police Department has also made new discoveries. We must go back to accept the new task of the Forest Police Department."

Aizawa shook his head, then forced a smile, and then he and Hanagata bowed again to thank everyone who came to see them off. Wait until the opponent has returned the salute. Aizawa led Hanata step by step towards the vehicle that took them to the airport.

"I didn't expect that the colleagues of the Metropolitan Police Department could leave us such an important clue before leaving. Put this business card away first, and when we go back, find the charcoal basin from the evidence storage room, and then carefully Let’s look for it and see if there are any imprints on it that look like fingerprints. Be sure to collect these traces one by one. Do you understand?”

"Hey!" With an uplifting shout, everyone was instantly reinvigorated.

"How about it, Kanai-kun, do you want to go to the laboratory with us and wait for the final results of the test! I think if it goes well, the fingerprints should be found soon!"

"That, senior! Can you give me that business card first? I want to take a picture of this business card. By the way, we will also make a copy of it during the course of the search. This will also facilitate us to track down the suspect's information as soon as possible."

"That's it, okay! I'll give it to you first, but remember, don't break this business card."

"Don't worry~www.wuxiaspot.com~Senior!"

Kanai said, and took out the business card from the other party's hand, and then put it in his pocket. Then, after seeing that everyone had left, he also quietly walked to a secluded place, and immediately called a person who was very important to him.

"30 seconds have passed!"

"One minute has passed!"

No one answered the other side of the phone, which made Kanai feel very bad. Could that guy have been caught by the police.

"This **** layman will actually leave so many clues, and he will make me stab you in the ass. Does it really mean that the Metropolitan Police Department's search class is all dry food?"
