National Forensic Doctor

Huilong Building.

This is an office building built in the early 2000s. From the perspective of those days, the standard was quite high, but now it seems that it is somewhat behind.

In terms of appearance, its curtain wall is not as handsome as the all-glass one, let alone the more expensive new material office buildings that are environmentally friendly in the new era.

Walking into the building, the management of the property has obviously improved. Whether it is sanitation or the maintenance of elevators and other equipment, it has an air of age, giving it the feeling of a boys' dormitory.

"This kind of office building shouldn't be for sale, right? Everyone rents it?" Liu Cheng looked around, looking a little worried.

If it was a purchased house, Liu Cheng believed that it would be difficult for the murderer to sell and hand over the house in such a short period of time. But if it was rented, wouldn't it be easy for the murderer to abandon the house and leave.

Jiang Yuan knew Liu Cheng's worry and comforted him: "At least the plant is here. It's good to be able to confirm the identity."

Liu Cheng thought so, nodded and said, "Even if he uses a fake ID, I can probably find out."

To rent this kind of office building, you have to provide an ID card.

From the perspective of the police, if a normal life becomes a chase, it can be regarded as half a failure. But this eucalyptus is a headless eucalyptus, and the difficulty of cracking it is obviously high. Even if it becomes a recovery, it will not be a loss. In the current domestic environment, unless the murderer hides in the mountains and forests to make a living by hunting and fishing, completely abandons his mobile phone, has no contact with the outside world, and completely separates himself from society, it will be very difficult to escape.

As far as the police force is concerned, if there are two or three people responsible for the investigation, it is more than enough.

With this mental preparation, Liu Cheng didn't say anything more, stared at the elevator to the 22nd floor, and when he went out, he already looked like a detective.

The first floor of the 22nd floor was rented by a home furnishing company. Liu Cheng first asked people to enter and exit the elevator and stairs before revealing his identity and entering with Jiang Yuan and others.

A group of white-bone spirits working at the office looked at Liu Cheng and others with expressions of sleep deprivation. Like the donkeys in the production team who suddenly saw people from other villages, their hazy eyes lit up, as if they were expecting something good to happen.

The camera behind Liu Chenghe captured everyone's expressions and movements at a glance.

If Jiang Yuan determines the type of plant, these video materials can now be used as clues.

The person in charge of the office hurriedly dealt with Liu Cheng and others. An ordinary medium-sized company in the capital still feels a little guilty when faced with criminal cases and criminal police members.

Jiang Yuan didn't need to worry about this. He took Mu Zhiyang with him and walked along the aisle.

Wang Chuanxing followed and took photos, filming the entire process as evidence.

After all, the coverage of the law enforcement recorders on the chests of the police officers is limited. When it comes to life-threatening situations, there is nothing wrong with taking more data.

There are quite a lot of green plants in the office area of ​​this company. Each employee has a pot of pothos placed near the walkway. The window sill area is also specially set aside for some green plants, most of which are related to the list. The overlap among them, such as narcissus, phalaenopsis, anthurium and white palm, clivia...

Jiang Yuan found more than 30 types of pollen on the blood clothes, and there were almost 30 types in large quantities. Most of them were common indoor green plants. It is normal to have duplications. However, the duplication rate of this company, It's already higher than normal.

Jiang Yuan's brows couldn't help but frown.

According to the concept of pollen map, this is a mismatch state.

As for the pollen of certain plants that is first contaminated from the company and then the pollen of certain plants at home, the overlapping levels of pollen are different. In other words, even if the pollen from two places far apart forms a Pollen maps of the same species but not belonging to the same group due to reasons such as quantity and location.

Jiang Yuan went to see a few more small offices and conference rooms, then returned to Liu Cheng and whispered: "There are some flowers that I haven't seen, but the ones I saw are basically on the list. The repetition rate is very high. Ask them if there are other plants nearby and where they come from.”

Liu Cheng was happy at first, and then frowned.

As a criminal police officer, the most annoying thing is this kind of tiny difference.

It's almost impossible to convict, and doing a lot of things is just in vain...

"Is that here?" Liu Cheng had to ask again.

This is a complicated issue, Jiang Yuandao: "Ask first."

Liu Cheng then called the person in charge of the office into a conference room. There was a row of police officers sitting opposite, in the posture of a three-chamber trial.

How could a well-known small manager have ever seen this kind of thing before? He said cautiously: "We are just a furniture company..."

"What are you asking, what are you going to answer?" Liu Cheng interrupted, and then said: "Who is raising these plants in your office?"

"Plant?" The person in charge couldn't even guess what the answer was.

Liu Cheng said "hmm".

The person in charge blinked, thought again and again, and then said more carefully: "If you are talking about office plants, we rent them from a specialized green plant company."

"Rented?" This answer was beyond Liu Cheng's expectations, and it was also beyond Jiang Yuan's expectations.

The person in charge seemed to have the answer and hurriedly said: "Yes, it's a green plant maintenance or green plant and flower company. They bring a brochure and you can choose the flowers in it, and there are also packages. After you choose, they will send the green plants. , they are also responsible for daily maintenance, and we don’t have to worry about it. Even if the flowers die, they take them back and replace them with new ones.”

Liu Cheng and Jiang Yuan looked at each other, and their expressions changed.

Since the company is opened in this model, it means that the customers are not just this company.

Liu Cheng immediately said: "Give me the company name and contact information, as well as the contract between you and the other party."

"Okay, okay." The other party agreed quickly.

"Also." Liu Cheng stopped the other party again, pondered for a moment, and asked: "Are there any employees in your company who have disappeared recently, or have not been here for several days?"

"No."

"Everyone here?"

"Yes, our company has people with perfect attendance," the person in charge said.

Liu Cheng said "hmm" and then said, "Go find the contract."

He was also afraid that the other party would lie, so he arranged for a police officer to follow him.

After a while, what Liu Cheng wanted was put on the table.

Liu Cheng looked at the company address and found that it was on the outskirts of the city. He hesitated for a moment and said, "Just come to the door."

It was impossible to call and negotiate with such important clues. It's a trivial matter for the other party to think he's a liar. He's just afraid that it might alert the enemy and let the murderer go away.

Jiang Yuan followed Liu Cheng without saying a word.

The suburbs of the capital are quite far away, but when Ningtai County Bureau investigates cases, they often have to go to Xiangzhen. The distance is not necessarily further, and it only takes more time.

Everyone entered the elevator in a hurry, leaving only two police officers to continue registering information and taking statements.

This is considered a link in the chain of evidence. On the other hand, after all, this company is within a radius of 2 kilometers, so suspicion still exists.

Along the way, Liu Cheng was in a good mood. Compared with the previous progress, which was no progress, this was more or less a clue.

Jiang Yuan closed his eyes and meditated the whole time.

The current case is being investigated based on forensic botany, but with the current configuration of the special team, Jiang Yuan is the only one who can understand forensic botany. In other words, the information was provided by Jiang Yuan, so he is the only one who needs to be held responsible.

At this time, Jiang Yuan was thinking about the various tests done in the laboratory to avoid missing anything.

"We're here." The driver looked at the navigation and drove all the way to the green plant company.

"This is a good place to kill people." Liu Cheng got out of the car and looked around. The vast green farmland extended to the mountainside. Long and low white, black, or blue greenhouses were clustered together.

Liu Cheng stretched and said: "The sky is high and the emperor is far away. There is no surveillance. It is also close to the roadside. There are water pipes and canals. The ground is still land. If you kill someone here, the blood will rush directly into the canals. It is convenient."

"If you want to kill people here, just bury the bloody clothes directly in the ground. There is no need to throw them all the way to the city center." A detective next to him laughed.

Mu Zhiyang said: "Provoke the police?"

"You... it's impossible. Those are all plots in TV dramas. How can anyone use their wealth and life to find something uncomfortable." Liu Cheng said, but his expression became serious. If this is the case, Zhengguang Branch really has a face that cannot be shamed.
