Things that solve crimes

In the kitchen, there was a large pot propped up on the large stove. It was bubbling, mist was rising, and large pieces of meat were tumbling in the pot.

Comrade Qin Laifu stood in front of the stove, staring at the meat in the pot. This stew is very particular. If the time is long, the meat will not be chewy. If the time is short, the meat will not be soft and rotten. The heat must be controlled just right. Okay, this is a test of the chef's skills, and unfortunately, Qin Laifu is one of the best.

Qin Yu was sitting in the living room, smelling the aroma of meat in the room, absent-mindedly asking when his brother would be back?

Hearing the sound of the door opening, Qin Yu immediately jumped up from the sofa and ran into the yard. He saw Qin Henian shouting at the top of his lungs, "Dad, my brother is back."

Qin Laifu heard that he turned off the fire, fished out the meat, and cut it. Well, the timing is just right.

"Brother, the car is parked in the yard. Aunt Qi's battery car was stolen outside not long ago." Qin Yu looked at the battery car outside the yard.

"Stolen?" Qin Henian was stunned, "Did you call the police?"

Qin Yu said, "Why didn't you call the police? You reported it on the same day. Aunt Qi just bought the car for six to seven thousand. It is said to be a brand-name product. I heard that not only Aunt Qi was stolen, but also several people had their battery cars stolen."

Qin Henian was speechless. What happened to the feng shui in Anxi Town recently? There were serial murders in the past and thefts in the future. There won’t be another case in the future!

Parking the car in the courtyard, the two brothers walked into the living room. Qin Laifu was sitting at the table. There were three bowls of hot beef soup on the table.

The large pieces of beef are soft and mellow, fat but not greasy, and the radish is full of juice, leaving a mouthful of flavor after one bite. Qin Henian ate bowl after bowl, finishing three large bowls in a row before he was satisfied.

Qin Henian was fed various delicacies during the day at home and studied at night, enjoying the five-day holiday.

Early on the sixth day, after breakfast, Qin Henian rode to the police station.

The task force was disbanded and Anxi Police Station returned to its former peace.

Qin Henian came to the office on the second floor. After the White Bones case, Yang Zhengnian consulted Medical Examiner Bai and received Medical Examiner Bai's approval of Qin Henian. He immediately applied to the Municipal Bureau for a medical examiner's position, and the superiors quickly approved the decision.

Turning on the computer, Qin Henian logged into the internal police website. This website contains all kinds of news from the police, combat power rankings, wanted orders, etc.

Fingerprints collected in a serial theft case in Anxi Town were found. Well, his brother told him about the case of battery cars being stolen in succession before.

If Qin Henian wants to upgrade his three skills, he must either gain experience in the practice room or use the skills to gain experience in reality.

In the last case, he performed two autopsies, and with the experience gained in the practice room, the skill of forensic pathology has gained a lot of experience, and he is not far from being upgraded.

Of the remaining two skills, only fingerprint comparison can gain experience in reality. Upgrading requires a lot of experience, and Qin Henian doesn't have to accumulate experience all the time.

Qin Henian clicked on the fingerprint image of the case and was a little surprised. What he clicked on was a bow-shaped pattern. Not to mention the deformation of the fingerprint, it was unknown under what circumstances it was extracted. It was blurry and incomplete, and it could only be seen on the fingertips. Only then can there be a basis for comparison.

Not to mention this fingerprint is a characteristic point, judging which finger it belongs to can make people scratch their bald heads.

The system automatically matched the two fingerprints, and not surprisingly, they failed to match.

Qin Henian didn't care. Which fingerprint could be uploaded to the information database without difficulty? It is only when the local police cannot solve the problem that it is uploaded to the system.

Of course, if it's a murder case, that's another matter. If you can't solve it locally, you can still apply for support from the municipal bureau. If the municipal bureau can't do it, you can also apply for support from the provincial bureau. The murder case will be solved, which is not just talk.

The system will only be uploaded unless it is really impossible to match. This situation is extremely rare. How rare is it? There has not been a single case in 30 to [-] years.

After closing the fingerprint comparison page and reopening the suspect's fingerprint image, Qin Henian observed the incomplete state of the fingerprints and slowly began to adjust the brightness and contrast.

In order to adjust the clarity of the fingerprint, Qin Henian spent more than an hour. When the image comes out again, the fingerprint direction can be seen more clearly than before.

Immediately afterwards, Qin Henian watched the direction of the lines and re-estimated the center point. The fingerprint was very incomplete. If he didn't estimate it, the system would automatically determine the center point.

Put it back into the software and press OK. 20 new fingerprints appeared but failed to match.

Adjusted again, 20 fingerprints again, still missed...

After repeating it many times, Qin Henian was still not discouraged. Fingerprint matching is like this. You need to be patient and very patient.

Comparing tens of thousands, hundreds of thousands or even tens of millions of fingerprints to find a correct fingerprint is really like looking for a needle in a haystack, which can last for days and nights.

Pressing OK again, 20 new fingerprints appeared. Qin He glanced over and paused on the sixth fingerprint.

When ordinary people look at fingerprints, they probably think they are all similar at first glance, and it is even more difficult to distinguish between bow-shaped and bucket-shaped patterns.

But for people who have been looking at fingerprints, especially criminal investigators who do fingerprint comparisons, different fingerprint features are like a little green among thousands of flowers, which are very conspicuous.

Qin Henian clicked on the sixth fingerprint, enlarged it and placed it on the left side of the computer screen. He clicked on the original fingerprint image and placed it on the right side of the screen.

When comparing two phases, we should not only look at the characteristic points, but also the similarity of the fingerprints. The human eye is better than a computer at one-to-one discrimination.

After winning the match, Qin Henian felt relieved and submitted the matched fingerprints.

The fingerprints he submitted will be reviewed by experts from the provincial department and confirmed to be correct. Then he clicks submit, and someone will notify the frontline police to arrest him. Of course, the local police can also arrest people. After all, no one will think that they have too many "performances".
