Grimm's face began to sweat as he heard this, but he knew in his heart that until proven guilty, there was no guilt!
As long as the other party cannot provide conclusive evidence, conviction is impossible.
Moreover, he thought he had done a very clean job. Whether it was fingerprints or traces at the scene, they had all been completely cleaned up. The most important thing was that he also used the method of killing in a closed room.
If you can't even explain the whole method, you can't convict him!
He forced a smile and looked at Bai Mu, "Sir, if you say such nonsense, I can sue you for defamation."
However, he still underestimated Bai Mu's criminal investigation thinking.
Bai Mu took out a photo at random. It was a photo of the deceased, hanging from the ceiling with a thick rope, his ankles tied tightly with the rope and hanging upside down.
"This photo is the common denominator of the entire case."
Bai Mu pointed at the photo and said, "After forensic examination, the victim died of poisoning. There was only one blunt force wound on his body."
He then looked at Grimm and said, "So everything is very simple."
Grimm still held on. "What do you mean by simple, officer? I don't understand a thing you're saying."
Bai Mu sighed.
"Alas, it seems you really want me to tear off your last fig leaf."
Bai Mu narrowed his eyes and looked at him, "I am giving you one last chance to surrender."
"If you don't appreciate it, you won't have another chance after I finish speaking."
He said this, but Grimm heard something else.
To Grimm, this was clearly a bluff, meaning that the Public Security Bureau currently had no important evidence to directly prove that he was the murderer.
He naturally relaxed a little and smiled slightly, "Officer, you've been saying some incomprehensible things since you came in."
"I don't understand."
Seeing him like this, Bai Mu shrugged and said, "Okay, okay."
"Senior Qingyi, can you come in and listen?"
The intercom responded, "Okay."
Soon, the iron door of the interrogation room opened and Qingyi and Nicole walked in.
"Bai Mu, I don't understand what you just said at all."
Nicole was also listening outside just now, and she was completely confused when she came in. Although she also knew some information about the case, she still couldn't be as sharp as Bai Mu.
Qing Yi, however, smiled and said, "Young man, please speak."
Bai Mu smiled slightly, picked up the materials, flicked the paper and said:
"It's very simple. First of all, the deceased died of poisoning, not from external forces. Then why did the murderer enter the crime scene and hang the deceased in mid-air?"
Qingyi narrowed her eyes and did not answer.
Nicole said, "I heard that criminals like to return to the crime scene to see their masterpiece. Maybe the criminal hung the deceased again for this purpose?"
Bai Mu shook his head.
"That's not the case. There's no missing money in the room, and the deceased didn't have any injuries on his body. I've seen many psychopaths, but even the most abstract mentally ill have motives for what they do."
"And this is the murderer's motive."
Bai Mu pointed his finger at the ankle where the rope was tied in the photo, and looked at Grimm.
Grimm was obviously a little flustered. He didn't expect that this guy could really deduce anything.
Nicole looked in the direction of Bai Mu's finger and said, "Is there any problem with this?"
This is clearly just an ankle hanging upside down.
Bai Mu nodded and looked at Grimm with a smile, "Mr. Grimm, you have been staring at my ankles since I walked in, right?"
"If my guess is correct, hanging the deceased with a rope was also to cover up something. The rope binding plus the pull of gravity can easily cause the original skin on the ankle to swell up or even break."
"If I'm guessing correctly, you have a particular fondness for the skin on your ankles, right? And since you pass through all the neighborhoods every day, plus you're a cleaner and a garbage truck driver, as long as you clean up the scene, no one will notice your presence."
Bai Mu smiled slightly after saying this. "Then let me guess, where do you put all your collections? A place where no one will see them, a place where you can always take your collections with you, and a place that can be cleaned every day without leaving any traces."
"Where could it be?"
After he finished speaking, his smile grew even more intense, like a hunter who had caught a fox by the tail, or like a spider on a web watching its prey.
Qing Yi replied, "For a cleaner, the only thing that matters is the garbage truck, and the only thing that meets these requirements should be the interior of the garbage truck."
"But what are you going to do about the locked room murder method, Mr. Shiraki?"
She also reminded us, "If there is no method of murder, our chain of evidence is still missing an important link and we cannot directly prove that he was the one who killed the person."
"Based on the principle of presumption of innocence, he will eventually be acquitted."
Grimm nodded. "Yes, even if what you said is right, you can't prove that I killed someone! Besides, besides, this is just speculation, and you don't provide any evidence."
Bai Mu nodded, "It's very simple. The poisonous substance has been detected. It's gas."
"All you need to do is follow the deceased and use your position to knock him out."
As he spoke, he took out another photo, which showed the blunt force trauma to the back of the deceased's head during the autopsy.
"After knocking the victim unconscious, they collected the necessary items and hung him upside down to conceal their motive for the crime. They then turned on the gas stove and locked the door from the outside with tape and other ropes to conceal their method of murder before leaving."
