Bai Song is indeed worried about this, he asked around, and the three workers all said that they had never seen this man, and they had not met anyone who left halfway in the past few days.

"Bai Detective, these people don't look like lying, could it be that there are other workers in this bathing place?" Zhao Han asked.

"Definitely, how can this kind of store fix a few people, it will always change, and it is normal for them not to confess to others, after all, it is not good for them at all. ”

Guests will get tired of it, and these will definitely change regularly.

After leaving the three inquiry rooms, Bai Song found a room where no one was, closed the door, and discussed with Zhao Han.

"Yes, White Team, this situation is very difficult to handle, I have worked on this kind of case when I was in the Xijing Branch before, these workers are particularly difficult to pry their mouths open, unless their interests are involved, they will not let out a fart. Zhao Han said: "You still have to coerce and lure, the only rule." ”

"Hmm. ”

The two were chatting, and Zhang pushed the door in: "White team, what are you doing here?"

"Discuss something, what's wrong?" Bai Song asked.

"The two things you said before have been clarified. First of all, the cleaners in this place generally go to the equipment room once every three days, because they usually put large barrels in the cleaning room, so they are not replaced very often. The second is that we checked their purchase channels, and the banana water there does contain carbon tetrachloride. ”

"The matter of carbon tetrachloride is worth digging deeper, and it is estimated that there is a black workshop behind it. Bai Song said: "This clue will be left 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 did not continue.

"I know what you want to say", Bai Song said, "If this cleaner is lying, then this case must be a homicide." Moreover, we ignore the problem that the cleaner is taking the key to open the door of the equipment room, which is easy to close and has to be opened with a key after closing. In addition, the cleaning materials in the equipment room are still worth a little money, and it also involves the safety of the bath, which must be locked on weekdays.

I even suspect that the way the door is locked is that the boss is afraid of not locking the door. In this case, how did the deceased get in? This door lock was also checked, ruling out the possibility of technical unlocking.

So, one percent chance the door is really unlocked, and the remaining ninety-nine percent is likely that either the killer has the key or the cleaner lied. ”

"However, I still haven't figured it out," Qu asked, "the cause of death of the deceased, so to speak... Is the murderer gambling? Is he not afraid that the deceased will lose the gamble, and the deceased will not drink the banana water, or open the door in advance, and then he will not die, and report him?"

"Yes, that's the key issue in 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 do you play the game?" Zhao Han also asked.

"I have such a speculation," Bai Song said, "of course there is no basis. It's that the murderer actually left a way out for himself. ”

"You mean, if the dead don't die... Eh, that is, if this person hadn't died, after he was released, he wouldn't have known that he had been victimized?" Zhao Han immediately understood what Bai Song meant.

"That's right!" Bai Song nodded: "This situation is called probability killing." ”

"I want to hear about it. Zhang Suo was interested, he had never heard the word before.

"To put it simply, let's say I want to kill you, I have prepared a large flower pot on the upper floor, ready to aim and smash you. But no matter how you aim at it, the probability of hitting it is only one-in-three. In this case, if it misses, that person will also think it is an accident, and the police may treat this matter as an accident without serious investigation.

In this case we encountered, if this person had been rescued by accident the day before yesterday and had not died, no one would have thought that he had been murdered, and he himself would not have felt that way. And when he's dead, we won't even be able to find out who he is. ”

After Bai Song finished speaking, Zhao Han immediately followed: "White team, according to what you say, there is a problem in this case." If, according to our previous analysis, for example, you mentioned that the deceased's wife was checking the post, and the deceased was so frightened that she hid in this house, then the deceased's wife must have been familiar with the neighborhood, otherwise how could she have checked here? If the deceased's wife was familiar with this place, the deceased was naturally also a regular customer. In this case, how can the murderer be confident that we will not be able to find out the identity of the deceased?"

Qu Suo glanced at Zhang Suo, his eyes were contemptuous, "You just told me what you thought about this?"

"Heroes see the same thing... Slightly the same..."

Zhang Suo was embarrassed, and Bai Song relieved the siege: "What Zhao Han said makes sense, one of the difficulties in this case is also 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 likely to be a foreigner." If it is from another province, it may be that the identity is lost, and the assistance of the nearby identity may not be in place. ”

In the western provinces, disappearances are not as serious as Tianhua.

The famous explorer Semitic once wrote an article that when he was rafting on the Yellow River, somewhere someone could fish out dozens or hundreds of general teachers every year, and a considerable number of them could not be identified.

If the identity of this case is not even clear, it is basically impossible to solve the case.

"So, there's another possibility. Bai Song said: "That is, the deceased was deceived." ”

"Fortune?" Qu said, "Then this is too ruthless." ”

This explains why the deceased's clothing and belongings were missing. Zhao Han gradually gained a little confidence.

On weekdays, in addition to Bai Song, there are so many bigwigs, and Zhao Han's shy character is always not good at expressing himself. In this five teams, Zhao Han and Bai Song are the closest, and this time he and Bai Song handled the case alone, and he felt that his state was much better.

"Then it could be an accidental death caused by a scam. Bai Song said: "However, if this is the case, it cannot be characterized as accidental death, and it may be characterized as illegal detention causing death." ”

"Uh..."Qu felt that he had to take a look at the derivation process of Bai Song and others.

Every time a point of view is overturned, Bai Song and another young man can quickly come up with a new and more reasonable one, so that in a few more rounds, the truth of the case may come out.

"White team, how about you rest assured and boldly reproduce the whole case?" Zhang Suo was full of interest.

"There's still a piece of the puzzle missing, so there's no rush. Bai Song said.

(Finally two more...)
