Bai Song did have this worry. He asked around and the three workers all said they had never seen this man, and they hadn't seen anyone leaving in the past few days.
"Detective Bai, these people don't seem to be lying. Could there be other people working in this bathing place?" Zhao Han asked.
"Of course. How can a store like this have a fixed number of people? They always change. It's normal for them not to confess other people. After all, it won't do them any good."
Guests will get tired of it, and these will definitely be changed regularly.
After leaving the three interrogation rooms, Bai Song found an empty room, closed the door, and started discussing with Zhao Han.
"Yes, Captain Bai, this situation is very difficult to handle. I have handled this kind of case before when I was in Xijing Branch. These prostitutes are very difficult to pry open their mouths. Unless their interests are involved, they will not say a word." Zhao Han said, "You still have to use coercion and inducement. That's the only way."
"Um."
The two were chatting when Captain Zhang pushed the door open and said, "Captain Bai, what are you doing here?"
"Let's discuss something. What's the matter?" Bai Song asked.
"We have checked the two things you mentioned before. First, the cleaners in this place usually go to the equipment room once every three days. Because they use large barrels of chemicals that are usually placed in the cleaning room, they don't change them very often. Second, we checked their supply channels and found that the banana water there does contain carbon tetrachloride."
"The matter of carbon tetrachloride is worth further investigation. There is probably a black workshop behind it." Bai Song said: "I'll leave this clue to you. As for the first thing, it means that there is a possibility of accidental death in this situation."
"But..." Zhang was about to say something but didn't continue.
"I know what you want to say," Bai Song said, "If the cleaner is lying, then this case must be a homicide. Moreover, we overlooked a problem, that is, the cleaner used the key to open the door of the equipment room, which is easy to close. Once closed, it can only be opened with a key. In addition, the cleaning materials in the equipment room are still worth some money, which also involves the safety of the bathhouse. It must be locked on weekdays.
I even suspect that the reason why this lock is designed to lock when the door is closed is because the boss is afraid that the owner will not lock the door. In this case, how did the deceased get in? The door lock has also been checked to rule out the possibility of technical unlocking.
So, there is a one percent chance that the door is really not locked, and the remaining ninety-nine percent chance that either the murderer has the key or the cleaner lied. ”
"But I still don't understand," Qu asked, "The cause of death of the deceased, according to this... Was the murderer gambling? He was not afraid of losing the bet, and the deceased did not drink the banana water, or opened the door in advance, and then did not die, so he reported him?"
"Yes, this is also the key issue of this case." Bai Song said: "There is a game problem in this case, that is, how did the murderer determine that the deceased would drink banana water and die?"
"Yes, how to play the game?" Zhao Han also asked.
"I have this speculation," Bai Song said, "Of course there is no basis for it. The murderer actually left a way out for himself."
"What you mean is, if the deceased was not dead... uh, if this person was not dead, after he was released, he wouldn't know that he was framed by someone?" Zhao Han immediately understood Bai Song's meaning.
"Yes!" Bai Song nodded: "This situation is called probabilistic murder."
"I'd like to hear the details." Zhang Suo became interested. He had never heard of this word before.
"To put it simply, let's say I want to kill you, and I prepare a large flower pot on a high floor, and I aim it at you. But no matter how hard I aim, the chance of hitting you is only one in three. In this case, if I miss, the person will think it was an accident, and the police may not investigate it seriously and treat it as an accident.
In the case we encountered, if this person had been rescued by chance the day before yesterday and had not died, no one would think that he was murdered, and he himself would not think so. And when he dies, we won't even know his identity. ”
After Bai Song finished speaking, Zhao Han immediately followed up with a sentence: "Captain Bai, according to what you said, there is a problem with this case. According to our previous analysis, for example, what you said about the deceased's wife checking on him, the deceased was scared and hid in this room. In this case, the deceased's wife must be familiar with the area, otherwise why would she check here? If the deceased's wife is familiar with this place, the deceased must be a familiar customer. In this case, how can the murderer be so confident that we can't find the identity of the deceased?"
Qu Suo glanced at Zhang Suo with contempt in his eyes, "What do you think about the thing you just told me?"
"Great minds think alike...alike..."
Zhang was embarrassed, but Bai Song came to the rescue: "What Zhao Han said makes sense. One of the difficulties in this case is the identity of the deceased. If the murderer is confident that we can't find out the identity of the deceased, then the deceased is most likely from another place. If he is from another province, his identity may be lost, and the nearby identity investigation may not be implemented properly."
In western provinces, missing persons cases are not taken as seriously as Tianhua.
The famous explorer Shemite once wrote an article that when he was drifting on the Yellow River, he found that in a certain place, people could fish out dozens or hundreds of cadavers every year, and the identities of quite a few of them could not be ascertained.
If we can't even find out the identity of the person in this case, it will be basically impossible to solve the case.
"So, there is another possibility." Bai Song said: "That is, the deceased was deceived."
"For money?" Qu Suo said, "That's too cruel."
"This can explain why the deceased's clothes and belongings are missing." Zhao Han gradually gained some confidence.
When handling cases on weekdays, there are so many big guys around besides Bai Song, and Zhao Han, with his shy personality, is always not good at expressing himself. In the Fifth Brigade, Zhao Han and Bai Song are the closest. This time, working on the case alone with Bai Song, he feels that his condition has improved a lot.
"Then this could be an accidental death caused by fraud." Bai Song said, "But if this is the case, it cannot be classified as an accidental death. It could be classified as death caused by illegal detention."
"Uh..." Qu Suo felt that he had to sort out the deduction process of Bai Song and others.
Every time after overturning a point of view, Bai Song and the other young man could quickly come up with a new and more reasonable one. If they continued like this, after a few more rounds, the truth of the case might come out.
"Captain Bai, how about you just feel free to recreate the entire case?" Chief Zhang said enthusiastically.
"There is still a piece of the puzzle missing, no rush." Bai Song said.
