Chapter 585 Survivor Bias

Facing Han Xu's burning gaze, Ma Mingtao smiled bitterly, without hiding anything, perhaps because he felt that there was no need.

"What else could it be? If a person is not ruthless, he cannot stand firm!"

Han Xu guessed that it was this sentence, but when he saw the ruthlessness flashing in Ma Mingtao's eyes when he said this, his heart could not help but shudder!

Is what this guy in front of him saying true or false? !

In Han Xu's dictionary, the word "faith" is next to the character "人"!

But guys like Dong Shushu and Ma Mingtao, who have demonic attributes, can't be described by a simple character "人".

People's words are credible, but what if the other party is no longer a human? !

What's more, everything Ma Mingtao confessed seems to be questionable.

For example, the real cause of Lu Lu's death, the autopsy report said she was drowned, but Ma Mingtao said that she was beaten to death by Dong Shushu.

The contradictions are so great that they don't match at all.

But when he thought that the victim might still have a breath left at that time, and was thrown into the well by these two demons, he experienced infinite despair...

Han Xu didn't even want to continue thinking in that direction.

But there is indeed another possibility!

That is, Ma Mingtao in front of him lied!

When Han Xu thought of this, he couldn't help but look up and down again at this old man who had been to the palace several times, but he seemed to be covered by a layer of something inexplicable.

It was as if a big net was swung over his head, and he couldn't see the truth that was so close at hand!

If Ma Mingtao lied, then he must have concealed something!

In other words, when he entered the room, he probably didn't see the dying or dead victim Lu Lu!

So what did Ma Mingtao see at the time?

Perhaps only the parties involved know this question.

Because both the victim Lu Lu and the murderer Dong Shushu are gone!

Han Xu had to admit that he was in a dilemma again!

Just like the Xueshan case, the people involved in the case died one by one, and even if there were any doubts, they could not be verified.

Only Jiang Zigui, the lawyer, was left as a survivor.

To use a more professional term, it is survivor bias.

Survivor bias generally refers to the fact that when the channel for obtaining information comes only from survivors, then this information may have a certain deviation from the actual situation.

And this deviation comes from a principle of natural selection after the survival of the fittest. The reason is that the survivors can no longer speak.

People only see the results produced by some kind of screening, but they are not aware of the screening process, so they ignore the key information that has been screened out.

At this moment, Ma Mingtao is in the same situation as Jiang Zigui, the lawyer!

It is also a typical example of survivor bias!

Because no one can prove everything Ma Mingtao said!

In the criminal identification process of Xiaguo, the emphasis is on evidence and not confession!

There is no way to convict the dead Dong Shushu just through Ma Mingtao's confession.

Not only is it not in line with the rules, but it is also irresponsible to the truth!

Han Xu certainly understood this, but for now, he could only verify everything Ma Mingtao said bit by bit.

"What did Dong Shushu use to kill the victim?"

The next step was to pry some details out of Ma Mingtao's mouth.

The murder weapon is always the most important physical evidence, and there is no other!

Han Xu did not find any murder weapon in the well, and he sent someone to verify it at that time.

The Nancheng Police Station directly salvaged all the remaining things in the well.

However, nothing valuable was found.

So Han Xu was sure that the murder weapon was not thrown into the well with the body.

"Officer Han, are you talking about the murder weapon?"

Ma Mingtao certainly knew what Han Xu was asking, but he shook his head again, "No murder weapon!"

Hearing this, Han Xu asked in confusion, "Didn't you say that the victim was beaten to death by Dong Shushu? Could it be..."

Without waiting for Han Xu to continue, Ma Mingtao continued, "Xiao Keba was suffocated to death by Dong Shushu."

"Suffocated to death?!" Han Xu frowned fiercely.

No wonder the victim Lu Lu might not have died on the spot.

This statement can actually be matched with what happened later.

Suffocation generally refers to the death of the victim's mouth and nose being suffocated by the hand or soft object, and the air is blocked, also known as suffocation.

Common soft objects include gauze, towels, pillows, wet cloth, wet paper and so on.

Of course, the most direct way is to use hands!

"So, the victim was suffocated to death by Dong Shushu's hands?"

Han Xu asked immediately.

There is no murder weapon, so there is only this possibility.

Ma Mingtao nodded and said nothing more.

"Is it true or not? You just need to answer, yes or no!"

During the interrogation, these responses with body language will be avoided as much as possible, after all, they have to be recorded.

"Yes."

"Then what did you say just now? When you entered the room, you saw Dong Shushu still beating the victim, and you stopped him?!"

Han Xu's ability to find loopholes is unquestionable.

Ma Mingtao was stunned by the question and couldn't help but shook his head and said, "Officer Han, you are really amazing! That bastard Dong Shushu drank a lot that day and didn't even realize that he was dying. So when I passed by, I was still beating him What a beating!"

After Ma Mingtao finished speaking, he stubbed out the nearly finished cigarette butt with his thumb and index finger, not forgetting to rub it a few times as usual.

This was not the first time that Han Xu saw the other party doing this action of extinguishing cigarettes. He couldn't help but stare at the thumb and index finger of Ma Mingtao's right hand.

Perhaps due to the long-term use of this violent method of extinguishing smoke, the fingerprints on Ma Mingtao's right thumb and index finger were almost burned away, leaving only two small burn scars.

"When did you develop this habit of smoking?"

Han Xu suddenly said this with a sudden leap.

Ma Mingtao raised his head in confusion, just in time to catch the young police officer's curious baby look. He subconsciously took his right hand back and said with a smile, "It's an old habit and it's hard to change."

Han Xu laughed when he saw this, and did not continue the topic, but returned to the right track, "According to what you said, when you first entered the house, Dong Shushu was still beating the victim. It was you who stopped Dong Shushu before going to investigate. Did he catch the victim’s breath?”

Ma Mingtao didn't know what the young police officer in front of him had intended, but there was nothing wrong with what he read back, so he couldn't help but nodded and replied, "Yes."

"Oh," Han Xu deliberately made the ending sound very long, then shook his head and said, "If that's the case, then how did you know that the victim was covered to death by Dong Shushu's hands? You shouldn't have been able to see the previous scene. Bar?"
