Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 256
Less than one-third, the fingerprint area is too small, and the number of feature points that can be marked is not enough, so it cannot be used as judicial evidence to identify suspects.

"The number of feature points is only eight. Let's see if we can match the target first. As for the murder evidence... you have to find it yourself at the Criminal Investigation Detachment of TZ City."

"Eight characteristic points..."

Lao Bai nodded: "It's not bad, as long as the target person can be locked in the fingerprint database, is it difficult to find judicial evidence?"

Liu Guodong also agrees.

"As long as the person can be found, the evidence should not be a problem. It should not be difficult to find the evidence by checking the time and space relationship between this person and the time of the crime."

"Besides, the number of feature points is not enough. It is just that the suspect cannot be proved guilty in the judiciary. But in reality, if the fingerprints of the eight feature points can be compared successfully, then this person should be the murderer."

This involves the probability of fingerprint comparison.

Although fingerprints are unique, everything is not absolute.

There is also a probability that different people have the same fingerprint.

It's just that the probability is very small, it is said to be one in 150 billion.

Of course, this is only theoretical data, and it is hard to say whether this theory is accurate.

Anyway, no one has ever seen such a situation where the fingerprints of different people are the same.

To put it a little deeper, it's like pi reckoning.

If pi is really infinite, then it proves that circles are real.

If the circle really exists, it means that the world is random.

Anything can happen by chance.

But if there is an end to pi, even if the number is too large to be added, as long as there is an end.

It shows that the so-called circle is a polygon.

It's just that this circle has too many sides.

But as long as it is a polygon, it means that the circle is designed.

The existence of human beings, everything that everyone does, can be designed.

When Lu Chuan was in college, when he was studying the uniqueness of fingerprints, he heard this from his instructor.

At that time, he thought it was a fantasy.

But if it is really a fantasy, what happened to his time travel?

"Ding!"

The crisp beep from the computer interrupted Lu Chuan's thinking and the conversation of the four of them.

Yang Sen took a stride and rushed to the computer.

Looking at the four big characters "comparison success" prompted above, his face turned red with excitement!
"It's done?!"

"I'm going to report to the captain!"

Liu Guodong leaned in front of the computer, confirmed the prompt that the comparison was successful, and left the office in a hurry, without even having time to read the information of the target.

Of course, Liu Guodong didn't even look at it. The specific investigation and handling of the case should be handled by the Criminal Investigation Detachment of TZ City. Haizhou only needs to send the information of the target person in the competition.

"Lu Chuan, it's yours!"

Yang Sen patted Lu Chuan on the shoulder hard.

This is a level that surpasses the capabilities of fingerprint identification experts from the provincial government.

This is the highlight moment of Haizhou Criminal Investigation Detachment.

The fingerprints that the provincial department could not deal with were sent to the Haizhou Criminal Investigation Detachment for comparison. The key is that the comparison was successful.

It is conceivable how important this incident is in establishing the status of the Haizhou Criminal Investigation Detachment in the province's fingerprint identification.

Lu Chuan also heaved a sigh of relief.

The identification and analysis of this fingerprint is indeed not easy.

Although Lu Chuan has advanced fingerprint identification and analysis skills, it should be said that he did his best this time.

Although the entire identification and analysis time is not long, the process is still relatively difficult.

Lu Chuan compiled the new software himself, thickened the separated fingerprints, and then completed the broken fingerprints, and finally compared them successfully in the system.

Fingerprints that are only one-third the size cannot be used as judicial evidence to identify suspects.

In fact, Lu Chuan didn't know whether the comparison was successful just now.

Fortunately, the result is good now.

Qin Yong's office.

"it is good!"

"Good good!"

Qin Yong called four good words in succession.

The case sent by the TZ City Criminal Investigation Detachment was not just a simple request for technical assistance.

Song Jiangguo, director of the Haizhou Public Security Bureau, has a very good relationship with the director of the TZ Public Security Bureau, and they were classmates in the same year.

Early this morning, Song Jiangguo personally called Qin Yong and asked to do his best to help the Criminal Investigation Detachment of TZ City.

Now that Lu Chuan has successfully separated the real murderer's fingerprint from the blood fingerprint, and compared the real suspect in the fingerprint comparison system, the pressure on the criminal investigation detachment of TZ City will be greatly reduced.

"Hurry up and send the fingerprints and the murderer's information to Taizhou. Lao Hu's eyebrows are probably on fire now."

Hu Guoqing, head of the Criminal Investigation Detachment of TZ City.

Now, I am attending the case analysis meeting in the conference room. The reason why it is not organized is because Ma Shaowen, the director of the TZ City Public Security Bureau, is sitting in the main seat with a gloomy face at the moment.

"Don't be dumb, tell me, what should I do now?"

Hu Guoqing looked around, he was the only one talking at this moment.

"The horse bureau, it was my improper command and insufficient handling of the case that caused the current situation. I... I will resign!"

boom!
Ma Shaowen slapped the table violently.

The loud voice scared everyone into a fright.

"Resign?!"

"You still want to take the blame and resign?"

"Innocent people were arrested and committed suicide in the detention center. You said that you resigned and it's over?"

"Hu Guoqing! I don't know if you have read the five blood characters on the wall of the detention center!"

"That's a human life!"

"Because of you! Ah!"

Ma Shaowen pointed at all the criminal police sitting here angrily: "Just because you are eager to handle the case, people died!"

"died!"

"Man! Dead!"

"I should be the one who resigned!"

"You should go to court!"

Ma Shaowen just came out of the office of the top leader in TZ City.

After being scolded, he came directly to the Criminal Investigation Detachment of TZ City.

He had already suppressed his emotions.

People cannot be resurrected after death, the key is to solve the case.

As long as the case is solved, everything can be reversed.

However, Hu Guoqing's statement made Ma Shaowen's anger suppressed in his chest, and he really couldn't suppress it.

The case analysis meeting does not say what to do next, but how to solve the case.

Talk about shit and take the blame and resign.

"Are you trying to pick someone up?"

"Let me tell you, even if you resign and go to court, you have to solve the case for me first!"

"Tell me, what should I do next!"

Hu Guoqing lowered his head, not daring to refute half a sentence.

To put it bluntly, Wang Shunyi's death could have been avoided.

Wang Shunyi is the innocent framed person who committed suicide in the detention center.

Of course, Hu Guoqing cannot be blamed entirely.

The detention center and the criminal investigation detachment are two units. If someone dies in the detention center, the detention center is the biggest responsible party.

"The fingerprints collected on the murder weapon found at the crime scene cannot be identified by the provincial department. Let us ask Lu Chuan, an expert from the Criminal Investigation Detachment of Haizhou City, for help."
