"Are they... so casual?" Chen Chuan took a quick step forward, like a shy primary school student, and secretly whispered behind Chen Shu.
After all, it was a murder scene. Although there was a possibility of suicide, it was against the rules to allow other police officers from other provinces to come in anyway.
In order to help Huang Mao, Chen Shu didn't care about these details.
"I carried a gun for our country more than ten years ago." Guess he must have heard Chen Chuan's muttering. Old Tang, who was walking in front, turned around and talked about his background as a soldier with a smile.
In the past, "I never met anyone of my own in the workplace, and there was no one to tell me all my stories."
So that’s the case, no wonder the Huangmao mother-in-law who was talking about Huang Mao was so enthusiastic when someone came!
Huang Mao and Zhu Yiba were former border police officers. In Yun Province, a border province of China and adjacent to the Golden Triangle, known as the most dangerous place in the world, of course they were particularly close.
Chen Shu did not pierce this thin veil and explain that he was a graduate of the police academy and helped Huang Mao retain such a master, so that he would have a place in the Criminal University in the future.
Chen Shu and Huang Mao had several brief exchanges. Although it was only a few words, it was enough to convince him that the other person's personality was indeed not suitable for front-line work in criminal investigation. On this point, he and Huang Mao's team leader agreed.
.
But a person with such a simple personality is quite suitable for technology.
Thinking about it this way, the criminal section of the public security system is the best place for Huang Mao. That place is full of technical masters with bad tempers, and everyone is used to coaxing them to work. There is no situation of deliberately making things difficult or isolating them.
.
"Team Chen! I'm waiting for you!" Huang Mao, who was already in the room, shouted enthusiastically and expectantly when he saw Chen Shu come in.
Chen Shu smiled. It was probably because of Zhu Yiba that Huang Mao was extremely enthusiastic and trusting of Chen Shu. He must have trusted his platoon leader very much back then.
After entering the door, Chen Shu exchanged a few words with Old Tang and found that the forensic doctor had basically not been involved in the trace area. He could understand the general things, but it was impossible for him to investigate and estimate it himself.
Come to think of it, the status of the forensic doctors in the southwestern border of China and the forensic doctors in the eastern coastal area are the same within the system. They are both ancestors and uncles.
"Toes pointed to the ground, he must have committed suicide." Old Tang glanced at the corpse that Chen Shu had placed beside him before, and concluded.
After hearing this, Huang Mao, who had been worried, breathed a sigh of relief.
After death, the body will harden and the feet will be fixed. If you were lying on the ground when you died, your toes would point to the ceiling. When you are hoisted up again, the stiffened toes should be parallel to the ground.
When a person commits suicide by hanging, his toes will naturally hang down because he cannot use the strength to hang himself. Therefore, shortly after death, the toes of the corpse are still pointing to the ground.
Chen Shu agreed with Lao Tang's statement, but according to the procedures, the required on-site inspection still had to be carried out.
Uneasy about leaving it to Huang Mao, Chen Shu rolled up his sleeves and prepared to inspect it himself. This was also Lao Tang's original idea when he invited him in.
He asked Huang Mao to send someone to carry the survey box from the trunk of the police car upstairs, and then started working.
By the way, it was almost an hour after arriving at the scene, and Huang Mao still threw the survey box into the car. With such a level of professionalism, Chen Shu was really worried about letting this guy end up.
Chen Shu first closed the door, then turned off the lights in the room, then turned on the footprint light, and used the principle of light emission to photograph the many shoe prints in the room one by one.
In this process, Chen Shu was not only an investigator, but also a teacher, teaching Huang Mao several simple and necessary on-site investigation actions.
Because the room is not large, many shoe prints overlap. As a hotel room, there are many guests coming and going, so the detection value is not high.
However, this is part of the investigation process, and Chen Shu has already engraved it in his bones.
Sometimes, unexpected surprises and even the key to solving a case often appear in this unnoticed corner.
Although he has never worked in the criminal investigation brigade, Chen Shu has handled cases in the agency for so many years and has learned some simple investigation techniques.
Sometimes, if there are no obvious signs of damage, blood stains, sweat stains or other valuable evidence at the scene, the Criminal Division will directly let the police from the police station directly inspect the scene.
As for Chen Shu, who has the highest number of overall hits, he is the best among them. When the criminal department is too busy and there are no people to come, he will personally extract fingerprints and take photos of the scene.
Why do we say there are thousands of lines on the top and one needle on the bottom?
The work at the grassroots level is intricate and complicated. It is necessary to implement the various policies of different higher-level agencies, and then to perform and complete their own work. This is a true portrayal of a police station policeman who wears multiple hats.
For example, the criminal investigation brigade will refer criminal cases such as gun cases, robberies, and arson cases to the police station in the jurisdiction for handling, and will designate a target number of criminal detentions every month; the security brigade, as above, also has a target for fines and confiscation;
For investigation, the same as above, there are indicators for criminal detention in cases of property infringement; for drug control, the same as above, there are indicators for forced rehabilitation and drug addicts.
The business team of the branch office, to put it nicely, plays the role of guiding business operations, but in practice, it is to distribute indicators and tasks to the police station, and then do nothing but wait for the statistics and summary at the end of the month.
Therefore, police officers who have been in the police station basically know a little bit about everything.
Maybe they are not as thorough in their profession as the masters of the various business brigades, but the case-handling policemen at the police station can still wield a few axes, and they are a jack-of-all-trades in the true sense.
While Chen Shu was working, he also observed Old Tang and Huang Mao.
Old Tang looked very calm. He must have seen too many corpses as a forensic doctor, just like a slaughterhouse master who has seen too many big pigs chopped into pieces. He was very calm.
Huang Mao, on the other hand, seemed much more cramped. His hands looked very busy moving up and down the scene, but in fact, he might not even know what he was busy with.
"Huang Mao, help me hold this footprint lamp." Chen Shu couldn't stand it anymore and said.
After receiving Chen Shu's instructions, Huang Mao breathed a sigh of relief, quickly came over to take the footprint light, and carefully set up the position.
After taking the photos, Chen Shu collected the things in the room one by one and put them in transparent evidence bags, such as toothbrushes, tea cups, and used toilet paper towels in the toilet.
For example, toothbrushes and toilet paper may look disgusting, but they are actually sharp tools for collecting evidence. They contain the DNA of people who have used them, so you can check them accurately.
What's interesting is that a cigarette butt was found under the toilet countertop. It looked like someone had smoked a cigarette while going to the bathroom, and threw it away after smoking.
The deceased was a female and it was unlikely that she smoked.
If this thing is found correctly, it is equivalent to the murderer actively providing the police with his ID card.
The above are all basic operations, there is no difficulty or skill, it is just a matter of being careful.
However, Huang Mao who was standing next to him was very excited. The moment he saw the cigarette butt, he directly concluded that there was a male person present at the scene, and this man must be the murderer.
Chen Shu was in a calm mood, but when he saw the cigarette butt, he suddenly thought of Zhang Yang for some reason. He didn't know if she would sit on the toilet like him and smoke to relieve her worries when she was under great pressure.
Shaking his head, Chen Shu focused on the scene again.
