On the morning of July 16, West Mining Branch.

"Captain, all the people in the relationship are here."

"Very good! Where is the forensic report?"

“Here.”

"Very good, then, let's eliminate it one by one..."

After overnight hard work, the West Mining Detachment had completed an investigation into the relationship between the victim Lin Kai.

The detachment conference room is now full of people. All the criminal police officers who can come from the district have arrived. On a blackboard, all the pictures are posted with big heads with names written on them.

Tang Ziqiang, Qiu Fang, Zhang Hu, Qin Lei, Zhang Xin, Liu Fang, Ma Linna, Zhai Hao, Cui Xiaonan, Guo Xiaochuan... There are ten people in the Lin Group, as well as some of the group's business partners, namely Lin Kai's friends in the shopping mall and six bosses.

As the richest man in Lin Kai, of course, he will also make friends with many leaders, but Gao Lai straightforwardly eliminated all leaders.

reason?

The leaders are not in good health, the murderer in our case is in strong health.

"Today, there are many new comrades. I am old and I don't know how to teach the police academy now. But when I come to us, I have come into contact with the practice of investigating work. Then I still hope that the new comrades can learn humbly. In fact, we criminal police, similar to doctors, have increased our ability through cases one by one. This case is a rare big case and has great learning value. Our Hunbei is a small city in a big city, and there are few valuable cases here. Although this is done well in public security, we will have fewer opportunities to learn. I am older and talk more. Next, let Comrade Mulan tell you about it."

After Gao finished speaking, he went there and Bai Mulan walked to the blackboard with a report.

"Everyone, Team Gao's words are a bit rough, but the truth is that. No matter what you have learned, there will be changes in practice. Even our investigation work has been changing and requires continuous learning."

In fact, Gaolai has a deep meaning. Hunbei City is aging more severely and is famous all over the country. This is beneficial to public security. There are really few major cases. At most, old men and women compete for the best square dance. They will squirt a few words and will be stubborn. They are busy with work, or they can only barbecue, skewers, and play ball, and health care. This is considered self-deprecating, but our place is quite comfortable. To be more vulgar, it is a case of dead people. Hunbei is like this. There is not necessarily one in a district with a population of more than 100,000 people a year.

Moreover, the small cities among big cities mentioned by Gao Lai are actually a special reference, that is, in terms of Hunbei, it is definitely a big city in the country. However, in terms of the construction of the police force, our criminal police have not yet been independent. Usually, each detachment is scattered in various areas. This is an old-fashioned approach and there are almost no big cities today.

In developed areas, the current criminal police detachment is independent, and the detachment can have a building, which means that at a level like Gaolai, you can have your own large office. But when you think that even the municipal brigade here works with the municipal bureau, you feel relieved.

The current case is a high IQ secret room murder. From the perspective of a doctor, this is a rare case. It would be a pity if you don’t do a good job of teaching.

Bai Mulan knew the master’s thoughts very well. As soon as she finished speaking, she expanded the report.

"The deceased was 65 years old, 185 cm tall, and weighed 140 kilograms. The forensic report determined the time of death of the deceased. On the evening of July 14, between 7 and 8 o'clock, the cause of death was strangled from behind by a rope and suffocated. The cyanide found only stayed in the nasal oral lip... In terms of the evidence department... the fingerprints on the scene were only the deceased and his wife Qin Lan... which basically met our on-site judgment."

Close the report.

"Next, it's our exclusion time!"

exclude?

Many of the police officers who took notes looked up.

"With the continuous development of technology, we have more and more methods, especially various surveillance videos, which leads to a problem, that is, what we face in the process of handling cases is not that there are few clues, but that there are too many clues, most of which are useless. Just like the saying, "As a saying goes, the flowers are fascinating, our work must eliminate useless clues and leave useful clues."

Many newcomers, like Liu Xiaogang, are very serious.

"For example, this site is a luxury apartment, and there is a shoe cover machine, so we have no way to obtain footprints on the site. Such an important clue is gone because of technological progress. Another situation is that the deceased is the boss of a large company, with a very busy business, and there are constant messages on phone and WeChat. We checked his three mobile phones and found that even if he was dead, there were still calls and messages coming in, so these naturally could not be used as clues.

I'm just an example, and then I'll start excluding it."

Bai Mulan turned around and began to reorganize the big heads.

"Although the deceased is 65 years old, he is huge in size, his nutrition and medical level, and we know that he also has a fitness card. Don't go in depth. Judging from this body shape, the murderer should not be a woman or a thin man, so now there are only 4 people left..."

Tang Ziqiang, Qiu Fang, Zhai Hao, Cui Xiaonan.

"The above is based on the height of 180 cm and 80 kilograms, and then their age is calculated. These four people are the most likely to strangle the victim."

On the blackboard, there were only four big-headed photos left.

At this time, Gao spoke, "Well, Guo Xiaochuan comes out alone, we have to keep an eye on it. I guess the comrades in the Economics Department will be useful."

"Yes." Bai Mulan did as she did, and then picked up another report, "Based on the conversation investigation last night, we found that four of them had absent proof."

All?

"Tang Ziqiang is responsible for the company's main business. On the 14th, he was on the ranch, 80 kilometers away from our city. The surveillance video showed that his car left the ranch at around 7 pm on the 14th."

"Qiu Fang, on the evening of the 14th, invited the customer... to Jinbi Bathing City in our city, and was doing big health care from 7 to 8 o'clock. The person who served him was technician No. 83, and there were also surveillance videos as evidence."

"Zhai Hao, he said he would celebrate his child's birthday. In a hotel, we have now obtained confirmation with the other party."

"Cui Xiaonan, his absence proved to be a bit strange. He said that he had a fight with his wife and had a lot of things fallen at home. When we used the phone to find his wife, his wife did not admit that there was such a thing. This... After all, it was a quarrel, and we still need to confirm it."

Bai Mulan will close the report again.

"The above four people are the main suspects in the direction of our investigation. These four people have absent evidence, but when you look closely, they all have some problems. Whether anyone is lying or not, we need further investigation. There are also some clues, such as around 6:30 pm on July 14, Qin Lan appeared in Fuhua Yujing and was likely to enter the victim's room. In addition, that is the problem of the murder weapon... Comrade Liu Xiaogang."

Liu Xiaogang was originally very enthusiastic about studying, but now when asked, his back was a little twitchy.

"That, there are outdoor goods stores within two kilometers of Fuhua Yujing, and some brands in the shopping mall, this one... is quite a lot."

Fuhua Yujing is a high-end apartment, and its location is of course very awesome. In such a place, large shopping malls are of course standard. Businessmen are very smart and know that rich people like outdoor sports, such as a real estate tycoon, who likes mountaineering very much.

There are 22 such stores, which shocked the comrades who went to investigate, but since they were ordered, they should be executed. They are also smart, so they got surveillance videos from various stores.

The merchants are also very smart. As for surveillance, at least it is necessary to prevent surveillance from stealing.

Then this is very good. As Bai Mulan said, the surveillance videos of these 22 stations are all clues.

Liu Xiaogang was assigned a task to watch these surveillance cameras, but where can I finish watching it?

Liu Xiaogang mentioned this situation and added, "I think the murderer had bought a rope, that is, a weapon, and this possibility is quite high."

When everyone heard this, they laughed and Bai Mulan rolled her eyes even more.

Gao Lai spoke at this time, "Comrades! What we need for criminal investigation work is criminal police, not sluts."

As soon as these words were said, they caused a burst of laughter, and Liu Xiaogang was also very embarrassed.

"Be serious!" Bai Mulan suppressed the scene.

Gao Lai continued: "Actually, what Liu Xiaogang said is not impossible, but our investigation work must grasp the greatest possibility. As for all the clues we have obtained at present, I think our investigation direction is correct."

Police are technical, but not without brains.

Then, nodded at Bai Mulan.

Bai Mulan continued: "According to the current clues, based on all conditions, this murderer should be the person known to the deceased, and he is strong and very familiar with Fuhua Yujing. The above four suspects are the most qualified suspects we can find at present. The problem now is that there is a proof of absence and the murder weapon."

Looking at Liu Xiaogang.

Liu Xiaogang doesn’t understand anything, “Don’t worry, leave it to me. I think there are 22 stores, which will make it easier for the murderer to hide himself. I will expand the scope. I will watch all the surveillance on the afternoon of the 14th and watch carefully.”

This determination is good, but it's hard.

Liu Xiaogang's work after this may be just to focus on surveillance.

"Captain!" someone came in and shouted, "Watch TV."

"ah?"

I turned on the TV immediately, and emergency news is being broadcasted at this time.

"The murder of famous entrepreneur Lin Kai has made important progress today. When the incident happened that day, Lin Kai's wife Qin Lan was suspected of being poisoned and murdered, and the police arrested..."

"Hello everyone, I am Zhang Tiecheng of the East Railway Detachment. People are safe and social stability..."

Qin Lan was arrested and Zhang Tiecheng was interviewed. Seeing this scene, Gao Lai slapped his forehead hard.

"Oh! This Tiecheng!...I'll go find Team Zhou!"

"master."

"Mulan, you will continue to investigate the case and focus on those major suspects first."
Chapter completed!
