But as for the suicide, the police at the time did not find any special reason for the suicide, nor did they find a suicide note.
So the police began to investigate as a homicide.
Based on Professor Maruyama Yuji's habits, they speculated that the criminal must have taken advantage of the professor's frequent intake of nutritional supplements and probably put poison into the capsules.
The reason for this speculation is that they did not find any injection needle holes on the subject, nor did they detect any sleeping pills on his body.
This shows that Professor Maruyama took the poison himself, rather than being forced to take it by injection or by being drugged.
This is also the only way to deliver a deadly poison into the opponent's body.
That's why this case is being investigated as a poisoning case.
Although the police at that time investigated people related to the professor, they did not find any valuable clues.
Given the situation at that time, almost everyone could be suspicious.
Moreover, making the poisonous capsule is not difficult, and secretly putting it into Professor Maruyama's medicine box is not a difficult task.
We also investigated whether someone had a personal grudge against Professor Maruyama, but we did not get any conclusive information, and the case was ultimately left unresolved.
"That's basically the situation." After Kamii Naoki and Tang Ze sorted out the ins and outs of the case, he couldn't help but say with a headache: "This guy really gave us a difficult problem!"
"If it wasn't a difficult problem, he wouldn't have told it." After recording the information in his mind, Tang Ze replied while putting the file away.
"Should we notify Officer Megure and have everyone search together?" Naoki Kamii suggested, "After all, there's strength in numbers."
"If there's no case, then that's fine. Let's go to the office and explain the situation to everyone."
Tang Ze is not a rigid person. Even if the evidence is insufficient and unconvincing now, as long as he explains the situation and draws attention, there will be no problem in re-investigating.
With so many people helping him, he wouldn't be stupid enough to fight alone.
But when the two returned to the office, they found that the room was empty.
After asking my colleagues in the clerical department next door, I found out that the police had indeed been dispatched.
