Chapter 93 Case Discussion
Cradling Xiao Sanmao's ashes as he left the evidence room and returned to UDI's office, Chen Yu found Jounouchi Hiromi chatting with Misumi Meiqin about something—it seemed they were both haranguing someone sitting on the couch.
"Hiromi, what are you two talking about?" Curious about what had united his girlfriend and Misumi Meiqin in common cause, Chen Yu asked Jounouchi Hiromi.
Hearing Chen Yu's voice, Jounouchi Hiromi quickly turned around, and seeing a box in Chen Yu's hands, she asked him, "Mr. Chen Yu, are you done with your work? I'm discussing a case with Dr. Misumi."
"Oh? Dr. Misumi's case? What, Hiromi, are you interested too, wanting to play the Goddess Detective Sherlock?" Chen Yu, perhaps trying to lighten the mood after being affected by the time spent in the evidence room, teasingly joked with her.
"No way! I just think that this case is just like Dr. Misumi said—the real culprit isn't the person the police arrested," Jounouchi Hiromi retorted, and went on to explain to Chen Yu, "I reviewed the evidence Dr. Misumi prepared, and as she said, the wounds and the weapon don't match.
The knives used in the victim's home are all specially made for left-handed people, but the wound was made by a right-handed knife, so the weapon the police found is wrong, and definitely, so is the culprit."
"That's not necessarily true, Hiromi. A mismatch between the weapon and the wounds is indeed a point of doubt, but it doesn't mean that if the weapon is wrong, the culprit must also be wrong," Chen Yu replied after hearing Jounouchi Hiromi's explanation, suddenly intrigued. He set the box aside, sat down, and shared his own opinion, which was different from Jounouchi Hiromi's.
Seeing Chen Yu not agreeing with her, Jounouchi Hiromi's brows furrowed, but she didn't get angry. Instead, she asked, "Then who do you think the culprit is, Mr. Chen Yu?"
"How could I answer you, Hiromi, without knowing the details of the case?" Chen Yu replied with a wry smile, but still started to analyze based on the information he had, as he had already heard the case details from Misumi Meiqin and it wasn't too complex, "The doubt that Dr.
Misumi raised is indeed an important one, yes, but this alone can only prove that the weapon was not the one discovered by the police, not that the suspect is innocent. To prove the suspect's innocence, there must be more conclusive evidence."
"What he's here for is none of my business." The man from the Nakado Department, displaying a 'keep out' demeanor, stood up with a cup of coffee and clomped his way into an adjacent room.
Watching the back of the man from the Nakado Department, Chen Yu couldn't help but shake his head slightly, "He seems to be a man with a story!"
However, that was none of Chen Yu's concern. Even if the man from the Nakado Department was burdened with a sea of blood grudges, it was of no relation to Chen Yu. Instead, it was Misumi Meiqin on the side who fell into a state of distress; she truly had no clue about the decisive evidence that Chen Yu had mentioned.
Seeing Misumi Meiqin's troubled look, Chen Yu also couldn't help but frown as he thought along with her. However, he was ultimately a surgeon, and despite having common professional ground with forensic pathologists, his specialty was different, and he couldn't think of a breakthrough at the moment.
It was Jounouchi Hiromi who seemed to have thought of something, and she asked Misumi Meiqin, "Dr. Misumi, what did the police identify as the murder weapon?"
"It's a custom-made household kitchen knife, why, Doctor Jounouchi, do you have any ideas?" Misumi Meiqin looked towards Jounouchi Hiromi.
"Hiromi, you mean the material, right?
If there is nothing wrong with the murder weapon, then the components it's made of must be detectable in the wound; but if the weapon is incorrect, then the components found in the wound will inevitably differ from those of the weapon," Jounouchi Hiromi said, which instantly made Chen Yu realize what she was trying to convey, as he had an epiphany, "Commonly available kitchen knives on the market are mainly divided into three types, ceramic, iron, and stainless steel.
But since you cut out and preserved the tissue from the wound, the material of the scalpel blade would inevitably contaminate the tissue sample, so testing for iron and stainless steel components would not be possible; you should check for silicon content in the sample! This is because both iron and stainless steel knives need to be sharpened."
"And the main material of a whetstone is silicon!" Misumi Meiqin also realized.
