The next morning, Chiba received three phone calls at home.

The first call was a phone call from Mr. Kobayashi, informing him that the school was closed today.

The second call came from Gregory, informing him that he had come to the hospital in the morning to record a confession about the bombing of a pharmaceutical company.

The third call came from Conan, informing him to go to the hospital in the morning to record the confession of the body found.

Come to think of it, the reason for the school holiday is also because the body was found and the scene needs to be investigated, right? But... Why go to the hospital to record the confession of the body found?

…… Two hours later, the hospital.

"I almost forgot," Chiba smiled dumbly when she saw Officer Twilight. "Before the transformation of the Forensic Criminal Investigation Center was completed, this was the best coroner's center in Rice Flower, and now these two cases are your responsibility. So it makes the most sense to stay here right now for a search lesson. ”

"Not necessarily," Conan stepped out of the shadow of the vending machine beside him. "I wonder if the explosion of the pharmaceutical company will be taken over by the Fourth Search Division, and now they are assessing the specific situation on the spot."

"Search the fourth section?" Qian Yu was slightly stunned. "What's that?"

"A section dedicated to crimes involving organized criminal gangs," Conan explained. "Once they have assessed it and deems it necessary, they will take over the case of the Search Section, because the Investigation Section is only responsible for cases where there is no involvement of a criminal gang."

(Author: The Fourth Division of the Search Division was reorganized into the Fourth Division of the Organized Crime Countermeasures Department in 2003.)

"Ahem," Officer Twilight coughed. Don't waste any time, since the burn patient hasn't woken up for a long time, let's record the confessions of a few of you who found the body. ”

"How many of us?" Qian Yu glanced at Conan, a little stunned. "Where did you come from—"

Before Qianyu finished speaking, he saw Mitsuhiko Mototai running out of a room next to him.

"Looks like I'm the last to arrive..."Chiba shrugged.

……

"That's right," Officer Twilight said thoughtfully. Coroner, what about the results on your side? ”

"That—" The coroner was a little embarrassed. There were no documents on the body, and it was impossible to determine the identity. But we speculated that it was a young woman in her twenties and thirties, and we suspected that it was a teacher at Didan Primary School, but the dean told us that no teachers were missing at the moment. As for the cause of death, we did not find any obvious wounds on the body, but reports from the scene said that the air in the chamber where the body was found was very turbid, indicating that the carbon dioxide content was extremely high, so we deduced that the deceased died of asphyxiation. ”

"The deceased is supposed to be between 29 and 33 years old and lived in the Shintogawa River in Toyama Prefecture as a child." Gregory's voice suddenly appeared. "The deceased had been a teacher for a long time, and there were still many lessons. She should be prone to symptoms such as low back and knee pain, so her body is not very good. ”

"How are you?" asked Officer Twilight in surprise. Who are you? ”

"I'm a doctor, you can call me Gregory, I'll look at the body again after your coroner's examination." Grigory waved his cane. "Please trust my diagnosis because it is absolutely correct. Mr. Officer, do you need to hear my reasons for making this diagnosis? ”

"Uhhh Officer Twilight hesitated, but finally nodded.

"First of all, the deceased's teeth had macula, and although this is a common symptom of dental fluorosis, the deceased's bone texture is not very coarse and not too sparse, so it can be ruled out. (Dental fluorosis usually coexists with skeletal fluorosis)" Grigory said as he looked at Officer Twilight. "So other conditions should be considered, and cadmium poisoning can be considered by softening the very serious bones and the pearl bracelet that is not a big problem, and the body has not been soaked in acid. As for cadmium poisoning, I'm sure everyone can recall what is a very famous incident? ”

"Painful?" Conan pondered for a moment and replied.

"That's right," Grigory raised an eyebrow. "The disease occurred in the Shentong River basin in Fushan County because Mitsui Metal Mining Company built a zinc smelting plant upstream of the Shentong River, and the wastewater from the zinc smelter contained a lot of cadmium."

"The onset of pain there takes about 10 to 20 years to accumulate, and given the condition of the corpse, the poisoning has already appeared, but it is still in the early stages, so she must have only been contaminated for a 'relatively short time' for 3 to 7 years. The cause of the pain was revealed in 1968, so it is reasonable to think that the deceased was born between 1961 and 1965, so I say she is now between 29 and 33 years old. We can also infer her age between 25 and 35 years old by her angle of 100 to 110 degrees of jaw; 80% of her age is inferred from the healing of the interdental space to be between 25 and 40 years old; From the 40% healing of the posterior transverse suture, it can be inferred that she is around 31 years old; The mid-jaw slit did not heal, and it can be inferred that she was between 26 and 32 years old... I also have a lot of evidence of her age, such as pubic morphology. ”

“。。。” Qian Yu looked at Gregory in surprise, and his eyes were full of exclamation for this unusually knowledgeable doctor.

"Okay... Officer Twilight was also taken aback by Gregory's near-miraculous performance. "That... Let's start by that criterion to find out what is possible—"

"Tetsuko Toya, 31," Conan interrupted Twilight, his eyes closed, and he recounted in a deep tone. "When I was a child, I lived on the banks of the Jinzu River, and when I was 5 years old, I came to Tokyo with my family, and I have lived here ever since. There is a stubborn problem in the joint, and the joint of the left leg was unable to move for up to an hour due to an inadvertent collision at the beginning of school. She has a slight macular spot on her teeth. ”

"Toya-sensei?" Mitsuhiko said hurriedly. "Conan, are you talking about Toya-sensei?"

"Toya-sensei?" Ayumi's expression instantly became very bad. "Conan, do you mean..."

"Won't it?" Motota was also taken aback.

"Oh, wait a minute," Grigory's expression was wonderful. "Did someone just say that the dean told him that no teacher was missing?"

"Mr. Toya left his job because he was getting married." Qianyu's face was also suspicious. "She quit on April 6 and then died...

"Is this a coincidence?" Conan asked bitterly. "It was clearly a murder orchestrated by someone at the school. Chances are, just after her last day of teaching, she died on her way out of school. On that day, our class bought a cake for Toya-sensei to celebrate her marriage... The teacher drank a bottle of wine that day and she was drunk, so we left early and left her there alone... ”

"Oh my God..." Even Qian Yu, who didn't participate in this experience, had already covered his face - less than half a month ago, he was also tortured by this guilt of hurting others, and he couldn't survive.

Is literature a condensation of reality? Rather, reality is the mother of literary works.
