Less than one-third, the fingerprint area is too small and the number of characteristic points that can be marked is not enough, so it cannot be used as judicial evidence to identify the suspect.
"There are only eight characteristic points. Let's see if we can match the target first. As for the murder evidence... we have to find it ourselves from the TZ City Criminal Investigation Detachment."
"Eight characteristic points..."
Lao Bai nodded: "That's not bad. As long as the target person can be identified in the fingerprint database, it won't be difficult to find judicial evidence?"
Liu Guodong also agrees.
"As long as we can find the person, the evidence shouldn't be a problem. If we check the time and space relationship between the person and the time of the crime, it shouldn't be difficult to find the evidence."
"Besides, the number of characteristic points is not enough, so it cannot prove the suspect's guilt legally. But in practice, if the fingerprints of the eight characteristic points can be compared successfully, then this person should be the murderer."
This involves the probability of fingerprint comparison.
Although fingerprints are unique, nothing is absolute.
There is a probability that different people will have the same fingerprints.
But this probability is very small, said to be one in 15 billion.
Of course, this is just theoretical data, and it’s hard to say whether this theory is accurate.
Anyway, no one has ever seen such a situation where different people’s fingerprints are the same.
To put it more deeply, this is like calculating pi.
If pi is truly infinite, then it proves that the circle is real.
If circles really exist, it means that the world is random.
Anything that happens may be random.
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 means 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.
Human existence and everything everyone does can be designed.
When Lu Chuan was in college, he heard his instructor talk about this when he was learning about the uniqueness of fingerprints.
At that time, he thought it was a fantasy.
But if it is really a fantasy, what happened to his time travel?
"Ding!"
The clear beep of the computer interrupted Lu Chuan's thinking and the conversation between the four of them.
Yang Sen took a quick step and rushed to the computer.
Looking at the four big words "Comparison Successful" on the above prompt, my face turned red with excitement!
"Done?!"
"I'll report to the captain!"
Liu Guodong came to the computer, confirmed the successful comparison notification, and quickly left the office in excitement, without even having time to read the information about the successful target.
Of course, Liu Guodong didn't even look at it. The TZ City Criminal Investigation Detachment was responsible for the specific case investigation. Haizhou only needed to send the information of the target person in the competition.
"Lu Chuan, I have it for you!"
Yang Sen patted Lu Chuan heavily on the shoulder.
This is a level that exceeds the capabilities of provincial fingerprint identification experts.
This is the highlight moment of the Haizhou City Criminal Investigation Detachment.
The fingerprints that the provincial department could not figure out were sent to the Haizhou City Criminal Investigation Detachment for comparison. The key is that the comparison was successful.
One can imagine how important this incident was in establishing the Haizhou Criminal Investigation Detachment’s position in fingerprint identification in the province.
Lu Chuan also let out 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 tried his best this time.
Although the entire identification and analysis does not take long, the process is still quite arduous.
Lu Chuan compiled new software himself, thickened the separated fingerprints, then completed the broken fingerprints, and finally successfully compared them in the system.
It’s just a fingerprint one-third the size,
It cannot be used as judicial evidence to identify the suspect.
In fact, Lu Chuan was not sure whether the comparison just now was successful.
Fortunately, the results are good now.
Qin Yong's office.
"good!"
"Okay, okay!"
Qin Yong shouted four good words in a row.
This case sent by the TZ City Criminal Investigation Detachment is not just a simple request for technical assistance.
Song Jiangguo, the director of the Haizhou City Public Security Bureau, has a very good relationship with the director of the TZ City Public Security Bureau. They were classmates at the time. .net
Early this morning, Song Jiangguo personally called Qin Yong and asked to do his best to help the TZ City Criminal Investigation Detachment.
Now that Lu Chuan has successfully separated the real murderer's fingerprint from the blood fingerprint and matched the real suspect in the fingerprint comparison system, the pressure on the TZ City Criminal Investigation Detachment will be reduced a lot.
"Hurry up and send the fingerprints and the murderer's information to Taizhou. Lao Hu's eyebrows are probably on fire now."
Hu Guoqing, leader of the TZ City Criminal Investigation Detachment.
Now, I am participating in a case analysis meeting in the conference room. The reason why it is not organized is because Ma Shaowen, director of the TZ City Public Security Bureau, is sitting in the main seat with a gloomy face.
"Don't be dumb, tell me, what should we do now?"
Hu Guoqing looked around, he was the only one who could speak at this time.
"Jockey Bureau, it was my improper command and lack of meticulous handling of the case that caused the current situation. I...I take the blame and resign!"
boom!
Ma Shaowen slammed the table.
The huge sound scared everyone and couldn't help but tremble.
"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 just resigned and that was the end of it?"
"Hu Guoqing! I don't know if you saw the five bloody words on the wall of the detention center!"
"That's a human life!"
"It's because of you! Ah!"
Ma Shaowen pointed at all the detectives sitting here angrily: "Just because you are so eager to handle the case, people are dying!"
"died!"
"Human! Dead!"
"I should be the one resigning!"
"You should go to court!"
Ma Shaowen just came out of the office of the top leader in TZ City.
The scolded bloody nozzle went directly to the TZ City Criminal Investigation Detachment.
He had already suppressed his emotions.
There is no resurrection after death, the key is to solve the case.
As long as the case is solved, everything can be turned around.
However, Hu Guoqing's statement made Ma Shaowen unable to suppress the anger in his chest.
The case analysis meeting does not tell you what to do next or how to solve the case.
Talk nonsense and resign.
"Are you trying to give up your choice?"
"I'm telling you, even if you resign and go to court, you have to solve the case for me first!"
"Tell me what to do next!"
Hu Guoqing lowered his head, not daring to refute even a single word.
All in all, Wang Shunyi's death was avoidable.
Wang Shunyi was 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 separate units. If a person dies in the detention center, the detention center is the most responsible party.
"The provincial department has no way of identifying the fingerprints collected on the murder weapon found at the crime scene. Let's ask expert Lu Chuan from the Haizhou City Criminal Investigation Detachment to help."
