Outside the appraisal room!

Director Su looked at the fingerprint matching results on the computer, the shock on his face beyond words.

This time the match went so smoothly and so fast.

Fingerprint matching is actually not like what is shown in movies and TV shows. You only need to scan the target fingerprint and input it into the matching system. The system can automatically compare and match it from the database based on the direction of the fingerprint.

The core of fingerprint identification is not the lines, but the feature points.

That is, the unique local details!

These details need to be marked by the trace inspector himself.

Due to the limitations of the individual's technical level, the feature points marked by different trace detectors are often different.

This kind of difference is not so difficult to explain if the fingerprints are relatively clear or it is an ordinary case.

Because in ordinary cases, only eight feature points need to be matched to preliminarily determine that it is the same fingerprint.

However, a serious criminal case like this one requires more than twelve feature points to match.

Therefore, if the feature points marked by the trace inspection are not accurate enough, even if the target fingerprint is in the database, it may not be matched.

At this time, the trace inspection needs to change the feature points or find new feature points.

This is very normal in the daily work of trace inspection.

Director Su originally thought that this matching would also go through this process and require multiple corrections.

But unexpectedly, after the fingerprint was entered into the system, it was matched successfully.

This is very rare in the identification of severely deformed and repaired fingerprints.

Not only does it show that the feature points marked by Shen Ting are also very accurately positioned!

It also indirectly proves that his fingerprint repair is also very accurate!

The other police officers were also surprised when they saw the matching results:

"A match?"

"Did it really work?"

"Zhou Huajia?"

Xiong Beibei next to him pretended to have expected this:

"What's the big deal? That's what I'm saying!

As long as Shen Ting says to try, he will definitely succeed! "

Xu Xinyi frowned slightly: "The owner of the fingerprint is named Zhou Huajia?

Is he the murderer in this case?

I don’t have any impression of him.”

“I have no impression at all.

According to previous investigations, shouldn't the murderer be in Xu Tuanjie's social circle? "

…

Shen Ting recalled the case information and felt strange.

The name Zhou Huajia is not common.

If it appeared in the case file, he would definitely remember it.

But now, he still has no impression at all.

None of the people involved in the case so far has this name!

With doubts, he carefully checked Zhou Huajia's information.

Male, 33 years old!

Height 173cm!

My hometown is Ta'na Village, Damajzhuang, Lun City, Meng Province!

His occupation is a construction site blasting worker.

Shen Ting raised his brows.

According to the information, Zhou Huajia was responsible for the blasting and demolition of buildings, blasting of underground rocks and other tasks at the construction site.

Five years ago, while having dinner with Dajing and his coworkers, he injured someone due to an argument and was sentenced to probation.

It was also at that time that fingerprints were left in the fingerprint system.

"Hannibal had previously speculated that the bomb used by the murderer was made of materials similar to detonators commonly used on construction sites.

Suspect he was working on a construction site!

This Zhou Huajia actually meets the requirements."

As Shen Ting was thinking, Qian Duoduo beside him spoke:

“Although we cannot be 100% certain, Zhou Huajia is the murderer in this case.

However, since the fingerprints matched, he was clearly a strong suspect.

Find the person first, bring him back and question him first!"

The surrounding police officers nodded immediately, and the search and arrest work began immediately.

Shen Ting then joined the case-solving group and informed everyone of his fingerprint extraction and matching results.

The group members were also surprised.

Qin Ming was particularly surprised. As a forensic doctor, he was aware of the difficulty of fingerprint identification in this case.

“Amazing, absolutely amazing!

Even damaged and carbonized leather can be used to extract and restore fingerprints. This is incredible!"

…

Shen Ting left a message asking:

"Does everyone have any impression of this week's Huajia?

Was there a person named Zhou Huajia among the victims of Xu Lixin's case?
