The crime occurred in an apartment building near the East Dayanghe Campus.

Putting aside the surrounding environment, this apartment building has a total of 13 floors, with more than thirty rooms on each floor. The shape of the building is not straight, with several bends. Each floor has a main corridor and four small corridors.

Corridor, there are houses on both sides of the corridor, and each house has a window.

Because of the special architectural style, a large number of houses here have been converted into daily rental housing. There are at least a dozen owners in this building doing daily rental housing. The rooms here can be rented daily or monthly.

The Yanghe campus of Dongda University is the campus of the College of Continuing Education. Generally speaking, the learning atmosphere is not good. It is summer vacation, but because of the epidemic prevention policy, many people do not go home and choose to rent a house here. In fact, there are

When schools were closed, many people chose to take online classes here. For them, this place has much more freedom than their own homes.

Here, you can have more fun than in a university dormitory. You can have fun as you want at night, drink, play cards and sing karaoke, no one will care about you.

The deceased was a second-generation rich man from a well-off family. His father ran a consulting company and was from Shandong Province. His family owned a Maybach. Generally, business people spend more than 1 million to buy a car, which is not considered very rich, but it is not bad.<

/p>

The deceased's name was Liu Zheng, male, 21 years old, 1.87 meters tall and weighing about 140 kilograms. The cause of death was poisoning. The specific type of poisoning still needs to be tested.

The witness is classmate Liu Zheng. Liu Zheng went out to eat with four friends last night. Everyone drank too much and did not continue to play, so they all came back to sleep.

Liu Zheng was a bit of a germaphobe. He slept alone and rented a room by himself. Everyone helped each other back and went back to their rooms to sleep. Because they all drank too much, no one remembered the specific time, but it was definitely...

These five people came back together.

Today at noon, Liu Zheng's classmate Wang Tongwei came to see Liu Zheng for dinner. No one answered the door or answered the phone. Then he tried it and the door opened directly.

After opening the door, he was startled by the hair all over the room. Then he saw Liu Zheng lying on the bed, still covered with hair. He called the police without even thinking about it. It was so intrusive.

As soon as I opened the door, there was a lot of hair all over the place. In addition, the curtains were drawn and the lights were not turned on, which made it feel really bad.

Wang Tongwei was so frightened that he did not dare to contact other classmates at all. He was afraid that other rooms would open like this, so he ran down the stairs from the fifth floor and called the police downstairs.

The police station in the jurisdiction arrived at the scene first. They put on the foot gloves and masks they brought with them and entered the house. They turned on the lights and then went to find Liu Zheng. They found that Liu Zheng already had body spots on his body.

Seeing this situation, the people from the police station exited the room directly. At this time, there was no one in the corridor, and many students were still sleeping at noon. The police station directly contacted the criminal police team, who had been on this floor before the criminal police team came.

There were two delivery guys, but the delivery boy was working hard, so he just glanced at the police and left.

After Lu Ling and others arrived at the scene, they immediately sealed off the nearby area. Of course, this blockade did not have much significance. There were seven or eight rooms in this area.

Now, we still need to visit and investigate the surrounding houses.

Forensic doctors and on-site investigators arrived quickly, and everyone frowned when they saw the scene.

Hair...too much...

What does the scene look like? The density of the hair is like a lawn.

Generally speaking, a person has 100,000 hairs. 100,000 hairs, each centimeter is about 10 grams. The average hair here is about 3 centimeters. In other words, 100,000 hairs is only 30 grams.

If a boy needs to cut off three centimeters of hair in one haircut, it would take at least 150 people to get the hair.

Not only that, there are also some slightly longer hair mixed in here.

In short, according to visual inspection, the number of hairs here is no less than 10 million, and the weight is estimated to be more than 5 kilograms. The source is unknown.

Five kilograms of hair collected together is not a lot. It can be easily carried in a handbag or backpack.

Everyone can easily judge that the source of these hairs should be a barber shop, and it is probably the kind of barber shop that offers "10-yuan quick cuts" because most of them are men's hair.

There are people who specialize in recycling broken hair, and the recycling price is very low, usually only 1-5 yuan per kilogram.

Shredded hair can be used as industrial raw materials to make amino acids. The main component of hair is keratin. After hydrolysis of these hairs with high-concentration hydrochloric acid, a variety of amino acids can be separated to produce animal nutrient solutions or feed additives. In the past, some were produced into

Soy sauce.

Of course, because human hair contains excessive amounts of heavy metals, the production of soy sauce is expressly prohibited.

If a person wants to prepare in advance, it is really easy to get chopped hair. After all, if you go to any barber shop and you are willing to pay a high price of 5 yuan per pound, you will definitely be able to buy it.

Captain Wang came over in person. After arriving, he was quite helpless when he saw the scene, but he still ordered to clean up quickly and collect all the hair.

This is not a simple matter. This room is about 25 square meters, and every place is covered with hair. But because this is a murder case, the leader did not let the students do it, but let the professionals do it slowly, bit by bit.

Collect, if there are footprints, they must not be erased.

Of course, Captain Wang also knows that it is of little significance. Anyone who can think of ways to design an on-site murder will not make basic mistakes.

There are not no mistakes in murder cases, but small mistakes are generally avoided.

About half an hour later, part of the scene was cleared, and the body was taken away for autopsy. However, an experienced forensic doctor pointed out that it was probably cyanide poisoning. However, no corresponding liquid or container was found at the scene.

Basically, suicide can be ruled out.

In this kind of case, it is necessary to check whether it is suicide. After all, some people like to engage in some fancy rituals to commit suicide.

At this time, everyone who ate yesterday has finished checking, and everyone probably knows something about the situation of the deceased Liu Zheng.

The deceased Liu Zheng was a carefree and devoted man.

He says he is flirtatious because he has had seven girlfriends in the past two years.

I say "special" because every relationship he has is unforgettable and emotionally moved. This is really not Liu Zheng's nonsense. Liu Zheng has a good relationship with several of his buddies, and he doesn't act pretentious when he is with his buddies.

Whatever you say, Liu Zheng puts a lot of thought into basically every relationship. Even if he succeeds, he still works very hard. Not only does he pay money, he also puts a lot of thought into it. He cries loudly every time he breaks up.<
