National Forensic Doctor

After the team members were assigned and tasks were assigned, Jiang Yuan plunged into the evidence room.

The eighteen members of Jiang Yuan's special case team are all involved in criminal cases, so someone has to take charge of the task of investigating the interpersonal relationships of the female warehouse boss.

Even though eight years have passed and many things have changed dramatically, for a murder case, most witnesses are still able to cooperate, but it just takes a lot of time and manpower.

It is conceivable that some people may not be in Changyang City now, but there are still those who should be tracked and asked.

The evidence is different.

The evidences that could be used were all lying quietly in the evidence room. Those that were not put into the evidence room that day disappeared into the long river of time.

The custodian in the evidence room spent a lot of time to take out most of the exhibits in the 112 case, handed them to Jiang Yuan, and said: "Actually, you can tell from the photos. The current photos are all very complete ”

"Well, thank you." Jiang Yuan didn't explain the three evidence boxes, so he went to the next door and looked through them one by one.

Given the opportunity to receive first-class merit, Jiang Yuan finally chose Mark Inspection - Tool Mark Inspection (lv6).

If the reward is left unfulfilled, it will not be effective. The tool mark test is something Jiang Yuan thinks is more suitable for him at this stage.

Forensic medicine also has forensic forensic science, but it is mainly used to deal with biological samples, that is, saliva, blood, semen spots and the like. The human body disassembled into pieces also counts, such as determining whether a bone fragment is from the skull or the knee. If it is the former, a murder case will be added.

Tool mark inspection mainly solves several questions: what it was made of, how it was made, whether it was made for this thing, and the professional identity of the perpetrator.

In his daily work, Jiang Yuan feels that this area of ​​demand is the most difficult for him to meet, and it is also what he needs most. Naturally, we have to turn to the system.

If the self-selected skill reward for the first prize is more detailed, for example, if Jiang Yuan is willing to specialize in the inspection of a certain tool, he can reach level 7.

But after some not too entangled thinking, Jiang Yuan still chose level 6, but with a larger range of tool trace inspection.

Judging from his current experience, lv6 skills are really enough. If he really reaches level 7, I am afraid that even the laboratory in Changyang City will not be able to satisfy him. What a waste if it turns into a dragon-slaying technique.

Moreover, in terms of tool mark inspection alone, a full range of tool mark inspections are absolutely useful. But if the types of tools are limited in order to upgrade to lv7, it will actually be quite restrictive.

After all, the police have no control over the killer's choice of tools. Although the main weapon of choice for domestic murderers is knives, Jiang Yuan cannot accept that he sees knife marks like gods and hammers like pigs.

Even with the level 6 tool mark inspection, Jiang Yuan actually felt that he was overkill.

Level 7 is most likely a Star Destroyer fighting mosquitoes, with too much firepower.

The most important thing is that Jiang Yuan is still full of confidence in the future. If he gets a first-class merit next time, or even a second-level hero model and a first-class hero, he will naturally know what lv7 is like.

Sitting in the evidence room, using the lv6 tool mark test, Jiang Yuan saw all the evidence in his eyes as if they were talking, each one rushing to report his current situation, past situations, background, and reasons for his origins. …

The evidence of 8 years has changed a lot, but no matter how big the change is, it is not enough for lv6 skills.

Jiang Yuan wore gloves and passed the evidence one by one, with very little pause time.

squeak.

Another policeman walked in.

The administrator of the evidence room immediately stood up and said respectfully: "Captain Zhu."

"Xiao Li, help me get a piece of evidence and I'll take another fingerprint." Zhu Huanguang, known as Team Zhu, smiled at the administrator. Zhu Huanguang is a legendary fingerprint expert in Changyang City. He has solved countless major cases and is the main force in receiving awards for meritorious service every year.

In the Changyang City Criminal Police Detachment, Zhu Huanguang also has a high status. Encountering people with difficult and complicated diseases

If you use your fingerprints, you will find Zhu Huanguang, and he will always be able to give a satisfactory answer.

Even in provincial capital cities, fingerprint experts like Zhu Huanguang are a scarce resource. In the annual provincial fingerprint competitions and ministries and commissions fingerprint competitions, Zhu Huanguang is a god-of-war existence and has made great achievements many times. It has been more than ten years now. To young people like Xiao Li in the evidence room, Zhu Huanguang is a living legend.

Zhu Huanguang himself also appreciates the respect he receives in the police force.

When people reach middle age, life is likely to be unsatisfactory. His parents are old and sick, the economy is in crisis, his wife is domineering, his children are naughty, his head is sparse, his figure is out of shape, and he has difficulty in excretion. Only work and career have lit up the light in Zhu Huanguang's life.

Allow him to illuminate himself, illuminate others, and have the opportunity to extinguish the light of others.

Occasionally, Zhu Huanguang also enjoys sitting in the office and extinguishing the life of a murderer.

Zhu Huanguang waited for Xiao Li to collect evidence and glanced around leisurely.

The evidence room of the Changyang City Police Station is similar to a small supermarket. Surrounded by beautiful-looking all-copper evidence cabinets, divided into many compartments, they were equipment purchased at the beginning of the construction.

Later, the space was not enough, so we started to put shelves in the middle, and put the evidence into evidence boxes and pile them up one by one.

In the room adjacent to the shelving area, several large tables were placed, allowing officers to examine evidence and take photos. There is also a camera above the head that can record the entire process.

When Zhu Huanguang saw this, his eyes were involuntarily attracted to a tall figure.

Jiang Yuan?

Zhu Huanguang actually recognized it at first sight, but he was afraid that he was hallucinating.

Jiang Yuan's impression on Zhu Huanguang was really profound.

Who has ever seen a fingerprint expert whose number of solved murder cases reaches double digits in a fingerprint battle?

It's not impossible. Every few years, we hear about something like this happening in a certain province, but who is so lucky to see it?

Who else is so unlucky as to face a fingerprint expert like this?

Zhu Huanguang still remembers the results ranking during the fingerprint battle.

At that time, Zhu Huanguang could actually see Jiang Yuan every day, but he never took a close look at Jiang Yuan.

Only then did Zhu Huanguang notice that Jiang Yuan was looking at a metal door lock.

After tidying up his clothes, the middle-aged Zhu Huanguang walked over and said hello: "Forensic Doctor Jiang, are you here to see the evidence?"

"Yes. A backlog of cases." Jiang Yuan also recognized Zhu Huanguang. The fingerprint battle lasted for more than a month, and Zhu Huanguang was actually the fingerprint expert who spent the longest time with him, because the two of them were involved in the office all year round.

Zhu Huanguang smiled, looked down at the door lock in Jiang Yuan's hand, and kindly reminded: "Actually, your fingerprint talent is so good, so just concentrate on doing fingerprints. Treat every day as a fingerprint battle, which is better than doing random cases." Can use your expertise."

"The same thing is said: "It's hard for Jiang Yuan to explain to Zhu Huanguang. My lv4 Chongqing-style single-finger fingerprint analysis method, plus a lv4 Qingdao-style single-finger fingerprint analysis method, and a lv5 image enhancement, of course have The set effect, but in terms of pure combat power, it should not be able to pass the lv6 tool mark inspection.

Therefore, just doing fingerprints is really a waste.

"I remember that you are particularly good at blurring fingerprints in images. Yes, you are also good at imaging." Zhu Huanguang recalled the past.

"Indeed." Jiang Yuan answered simply,

"Imaging is good, and your expertise in imaging should also be brought into play." Zhu Huanguang said with envy again.

Imaging expertise is a really profitable expertise. If he was an expert in imaging, he wouldn't be short of money.

If there is no shortage of money, there is a high probability that the wife will not be unhappy. If the children have money to make up for their lessons, finding a few more good teachers will probably be of no use, but at least it can reflect the attitude of your father and me that we have tried our best.

While Zhu Huanguang was a little distracted, Jiang Yuan's attention gradually returned to the evidence. After looking at the photos for a while, he started to unlock the door.

The clanging sound of the golden game awakened Zhu Huan

Light.

Seeing that Ruo Jiangyuan had dismantled the lock into parts, he put on a mouthpiece and looked closer.

"These are the traces of a marble hook in unlocking the lock. My skills are average. There are so many marks on the list. I guess I have been using marbles for a while. I don't look like a veteran." Zhu Huanguang is actually not only a fingerprint expert, he is also a master of trace inspection.

However, since the fingerprint examination, Zhu Huanguang's performance on fingerprints has become even better, and he has gradually specialized in doing fingerprints.

But Zhu Huanguang believed that he did not have time to delve into other skills of trace inspection, and Jiang Yuan was even less likely to have time. How old was he, even if he started practicing from his mother's womb?

"Actually, it's not just the traces left by the hook and pin used to hook the marbles." Jiang Yuan took out his mobile phone and started taking pictures, adding: "There are also new keys here. Traces of being poked open multiple times."

Zhu Huanguang was stunned. Can this be distinguished?

He lowered his head and looked at the disassembled lock cylinder more carefully.

For a long time, Zhu Huanguang only looked at the specious and false, and couldn't help but ask: "What can the traces you mentioned multiple times prove?"

"It proves that someone first tried to open the lock with a newly assigned key, but the key was inappropriate or for other reasons, which caused him to fail to open the lock, and then he used a marble to open the door." Jiang Yuan paused and said: "It shows that the crime was premeditated and the suspect had access to the key."
