Rebirth of Conan as a Detective

The death scene at dusk has a unique sense of horror beauty. There are obviously no ghosts or the like, but once the topic of death is involved, it always makes the vest chill.

As a place for collective suicide by burning charcoal, the Sato family quickly fell silent after experiencing the initial hustle and bustle. Watching the lively crowd dispersed, only the cordon around the house was left.

Under the leadership of the Maori police officer, Gao Cheng and Dr. Sancheng entered the yard through the cordon, and then followed into the house after putting on shoe covers.

The typical Japanese-style house is a bit like the old house where the smart incident happened in the past. I don't know if it was affected by the case. It is always depressed when I look at it, and the air seems to be filled with despair.

The scene of the incident was in the living room, a room of about 16 square meters. Except for the corpse was removed, the rest remained the same.

Gao Cheng used a flashlight to check the blocked doors and windows, and silently looked at the room furnishings based on the photos provided by the police.

The dwarf was on 4 coal stoves, and the body was lying on the tatami around the dwarf, and it looked nothing unusual.

"It's so miserable..."

"In short, that's it."

The Maori police officer is always a little cautious in front of Gao Cheng. After all, he can become a special consultant at the head of the General Administration, and his energy must be careful.

"We suspect that Sato Masaichi froze to death the girl, then moved here with a car, and then burned charcoal with the other two to commit suicide..."

"But why do you have to freeze to death before you bring it here? If you plan to burn charcoal to commit suicide, wouldn't it be fine to do it here?" Gao Cheng questioned.

"Well, so maybe it was after killing the girl that I thought of burning charcoal to commit suicide..."

"There are also contradictions in time."

Gao Cheng browses the call-up post posted by Masaichi Sato in the suicide forum.

"The posting time was a few days ago, and the time that the girl has frozen to death cannot be too long..."

"Moreover, this doesn't match the calculation result," Sansumi wrote and drew on the document. "I heard that when the police arrived at the scene, the indoor carbon monoxide content was 204ppm, but judging from the volume and the amount of charcoal burned here, There should be up to 1800ppm of carbon monoxide in the house..."

Sancheng walked to the window pasted with tape, the scene was very tightly sealed, and only one door could be opened and closed.

"The ventilation holes are blocked, the window seams are sealed with paper and tape, and the door seams are also very small. The airtightness of this room is already quite high. Judging from the suicide results, 204ppm is too low."

"It's indeed a bit low," the Maori police officer wondered, "but what does this mean?"

"From the time the three died to the police coming over," Sancheng said, ignoring Maori and looking at Gao Cheng. "Someone has opened the door of this room, so the carbon monoxide content will decrease... It was this man who took the girl. Moved into the house."

Gao Cheng looked away from the room, and turned to Sancheng stunned.

Obviously a forensic doctor, so professional investigating cases...

"So the prisoner is someone else?" Maori police officer stunned.

"This makes the most sense."

"That is to say, the prisoner knew that the corpse burnt charcoal to commit suicide would be orange-pink, so he mixed the frozen corpse into the suicide scene?"

The Maori police officer was a little confused, so he interrupted Sancheng's conversation and rethinked: "Is this really possible?"

"If there is no dissection, this is a perfect crime," Sansumi looked at Gao Cheng lightly, "Kito Detective, if it were you, should you be able to profile the prisoner?"

"Character profile?" Gao Cheng regained his senses, "I'm not good at this kind of thing... It should be someone who knows suicide very well, and knows that there will be people in this house who collectively burn charcoal to commit suicide. It is possible that they have logged on that suicide website Very large, living alone, withdrawn personality, and the age difference between the girl and the murdered girl may not be too big, the most likely is to meet the two girls through the Internet..."

Seeing that the sights of Sancheng and Maori police officers fell on him, Gao Cheng said with a headache: "There are too few clues, and I can only guess these, but starting an investigation from that suicide website may be rewarding."

"No," the Maori police officer stunned. "It's great to know so much. If there really is another girl named Xiaohua, it's just like an unknown prophet. Detective Jioto knew from the beginning that Sato was not. The murderer, right?"

"It's just basic logical reasoning. Don't the detective just want to know what's inside before opening the box?"

Gao Cheng collected the information and smiled at Sancheng: "Thank you, Dr. Sancheng, I will follow this case. If you find the prisoner quickly, the girl named Xiaohua will be less dangerous."

"I should say the trouble is," Sancheng handed his business card to Gao Chengdao, "I will notify you when the check result comes out."

...

At night, the city's detective office.

When Xiao Ai sat down for dinner, Gao Cheng was still checking the information on the second floor, and he was very fascinated.

"About the use of coal to kill and suicide, about the forced suicide case of a family of four in Urawa City...Misumi Mikoto?" Xiao Ai leaned aside and looked at the computer screen, "Is that Dr. Sansumi's thesis?"

"research paper."

Gao Cheng rubbed his sore eyes.

"The mother mixed sleeping pills into black tea to make her husband and son fall asleep, and then lit coal in the room to fill the house with carbon monoxide. In the end, only the daughter who slept in the next room was sent to the hospital in time for rescue. If 30 minutes later, it might be possible. Will cause brain damage..."

"Doctor Sancheng?"

"Yes, I checked this case. The dean and his eldest son of Amemiya General Hospital died collectively in a house in Urawa City~www.NovelMTL.com~ The only girl who survived seems to be Sansumi, who was taken by the dean’s sister’s family. After adoption, she changed her name from Amamiya Mikoto to Misumi Mikoto..."

Gao Cheng put a copy of the case information faxed by the Metropolitan Police Department on the table.

"What kind of mother can do this kind of thing, it seems that I haven't found it out back then. However, it is amazing that Dr. Sansumi who encountered this kind of thing did not become an extreme criminal..."

Xiao Ai didn't look at the information: "Why do you care about that Doctor Sancheng so suddenly?"

"Huh?" Gao Cheng was taken aback.

"Does the average person check this information when they meet for the first time?"

"Well..."

Gao Cheng let go of the document under Xiao Ai's scrutiny gaze.

"I'm just a little interested in the case of forced suicide..."

"and then?"

"Then, don't you have to investigate the case tomorrow? Although the murderer should not be Sato Masaichi, I still want to understand a little bit of this suicide case..."

"Really?" Xiao Ai put away his suspicious gaze for the time being, "Obviously, I was only going to participate in the forensic science exchange meeting. Why did it become an investigation?"

"Isn't it right? You can clearly see the importance of forensic medicine in solving cases. If you want to become the world's number one detective and maintain a 100% detection rate, you have to keep learning."

Gao Cheng thought of Dr. Sancheng during the day, and crossed his fingers in agreement: "Forensic doctors are really good. With the information they collect, investigating cases seems to be easier. I feel that my thinking has become clearer. Knowing that the appearance of freezing death is the same as carbon monoxide poisoning, and the cause of death is judged from the accumulation of blood in the heart, and the indoor carbon monoxide concentration is inferred that someone has entered the room halfway. If the gastric juice is detected, it may be possible to know where the girl’s last meal was. Have……"

"Are you still eating?" Xiao Ai asked.

"eat."
