"Gangster ......" Qianyu staggered. If I'm not mistaken, the Koenji family seems to be a real estate chaebol? Do you all participate in the gang......"

Wait a minute, according to the information that Gin revealed before, Belmode in the organization seems to be from a wealthy family? In this case, it seems not impossible for the daughter of the chaebol family to join a gang.

"Gentlemen forensics," Grigory asked abruptly, aloud into the empty room. "Did you find anything?"

“？” Qian Yu was stunned, because there was no one here.

A few seconds later, right in front of Qian Yu, the wall, which had no gaps, suddenly parted to both sides, revealing a door, and a man in a white coat walked out.

"According to our examination, there are crushing marks on the end of the remnants of the deceased's little toe, and we believe that the murderer ripped the little toe directly from the foot of the deceased Keiko Takaenji with something like a vice."

"Did you find anything that could be the cause of death?" Grigory asked.

"Maybe the cause of death was that little toe?" The white coat shrugged his shoulders after speaking. "Of course, Fisher came up with the idea, but I don't think it's possible to kill him by dropping a little toe."

"Give Mr. Takaenji a blood clotting test and an aspirin tolerance test, and by the way, investigate his vWF (von Willebrand factor), and then check the GPII.b and GPIII.a genes." Grigory said after a moment's thought. "It's unlikely, but what if there is a coagulopathy? In addition, if I remember correctly, the results of the physical examination that this eldest lady did when she had an artificial meniscus replaced should still be there. ”

(Coagulopathy can be caused by hemophilia, von Willebrand disease, vitamin K deficiency, liver disease or platelet weakness, decreased acquired factor VIII, and even severe liver disease.) Because Keiko Koenji has died, it is difficult to check for diseases without a genetic history, and only diseases with family inheritance such as hemophilia can be investigated. The coagulation test is to check for hemophilia with X recessive inheritance, because if a female patient is sick, it means that she has a problem with both X chromosomes, so the father must have a problem with the X chromosome, so the father must also be a patient; vWF was investigated because von Willebrand disease is an autosomal disorder—all but a few subtypes are autosomal dominant. The reason why he didn't investigate the entire family was because his job status at this time was a forensic doctor, and it was impossible for these police forensic assistants to do this kind of thing for him that had nothing to do with the investigation of the case; The GPII.b and GPIII.a genes are tested to check for platelet weakness, an autosomal recessive disorder. ）

At that moment, a computer that had been on in the room suddenly beeped, and then a window of video software opened on the screen - one on the left and one on the left and one on the screen. Judging from the contents, the picture on the left should be the camera of the Metropolitan Police Department's standard interrogation room.

On one side of the interrogation room sat Officer Renzaburo Shiratori, while on the other side was a young white man who looked to be of European and American ancestry—a close-up of his expression in the picture on the right.

"Oh," said Grigory, walking briskly to the computer, in his office chair. "The video from the interrogation room is here."

"Are you the teacher who taught Miss Keiko's Spanish, Mr. Maurisio?" Shiratori Renzaburo asked.

"The correct word is a governess," Mauricio corrected. "Can you give me a reason to forcibly bring me here while I was still in class? After all, you're going to bother my students and me a lot if you're doing that. ”

"Keiko-sama is dead," as Shiratori Renzaburo's body leaned forward slightly, assuming an aggressive stance, and Gregory and Chiba's gaze turned to the close-up on the right. "She was kidnapped and killed at least 24 hours ago."

Grigory raised an eyebrow.

"Judging by your expression," Shiratori Renzaburo asked. "Miss Keiko's relationship with you is more than just a master and apprentice, right? Ordinary teachers don't have that kind of expression. ”

"......" Mauricio looked at Shiratori Renzaburo and nodded. Yes, we are in a relationship. We're even ready to go on a hike to South America next week. ”

"Oh?" Shiratori Renzaburo glanced at the paper in front of him. "You must have already bought tickets next week, right?"

"That's right," Mauricio nodded. "So what?"

"Miss Keiko is a methodical person, and she has a habit of writing everything down in her diary—but something so important is not written down in her notebook, whether it's plans for next week's trip or airline tickets. Have you not discussed when we will meet? ”

"We only agreed on the time and place of the rendezvous," Mauricio replied. "I traded my miles for a ticket, and she was planning to take another flight......," he said, with a grim smile on his face. We were going to meet in Chile and have a sweet ......"

“？” Qian Yu was stunned. "This ......"

"When I looked at her room before, I didn't notice that she was ready to go out, did you?" Grigory frowned. "What's going on?"

After thinking for a few seconds, Gregory's brow furrowed. "Let's go back to the Gaoyuan Temple Mansion and talk to their subordinates."

…… On the sedan driven by the white coat that took off the white coat.

"Although there was heavy bleeding, the clotting ability was not abnormal." Grigory looked at the document in his hand. "So there's no way a small wound like that would have killed her."

"The equipment department shows that they have prepared a brand new medical alert bracelet for Miss Keiko to replace the bracelets of other hospitals," Chiba also looked at the pile of papers. The note on the bracelet states that she is at least allergic to penicillin...... But then again, Mr. Gregory, why do we have to go back? Didn't you say you don't get much information anymore? ”

"The on-site police can do it," Grigory replied. "But this time our purpose was to talk to each other—to find someone to talk to with Miss Keiko, most likely a young, handsome and considerate boy of the same age. If Keiko has anything to say, she will definitely talk to such an eye-catching and warm-hearted person. ”

When the car turned around the corner, the eyes of Chiyu, Gregory, and White Coat were all drawn to one person at the same time.

It was a young man in a gray shirt, and this young man was actually climbing a wall!

"I think the wall he's climbing looks like a ......," Chiba said in surprise.

"It's the wall of the temple house," Grigory motioned to his coat to put on the brakes. "We might get something out of talking to him."
