Chapter 649 Provocation?

Huilong Building.

This is an office building built in the early 2000s. From the perspective of that year, the standard was quite high, but now it seems a bit behind the times.

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

Walking into the building, the property management is obviously lagging behind. Whether it is the maintenance of sanitation or elevators, it shows an old atmosphere, and it feels like a boys' dormitory building.

"This kind of office building should not be sold to the outside, right? Everyone rents it?" Liu Cheng looked around and looked a little worried.

If it was a bought house, Liu Cheng believed that it would be difficult for the murderer to sell the house and hand it over in such a short 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 worries and comforted him, "At least the plant is there, so we can confirm his identity."

Liu Cheng thought so too and nodded, "Even if he uses a fake ID, it's probably still possible to find out."

If you rent an office building like this, you have to provide an ID card.

From the police's perspective, a general murder case can be considered half a failure if it becomes a pursuit. But this case is a headless case, and the difficulty of solving it is obviously high, so it is not a loss even if it becomes a pursuit. In the current domestic environment, unless the murderer hides in the mountains and forests to hunt and fish for a living, completely abandons his mobile phone, does not contact the outside world, and completely isolates himself from society, otherwise, it will be very difficult to escape.

In terms of police force alone, if there are two or three people responsible for the investigation, it is more than enough.

With this mental preparation, Liu Cheng said nothing more, stared at the elevator to the 22nd floor, and then went out, he had already taken on the appearance of a big criminal policeman.

The first floor of the 22nd floor was rented by a home furnishing company. Liu Cheng first asked people to check in and out of the elevator and stairs, then revealed his identity and entered with Jiang Yuan and others.

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

Liu Cheng and the camera behind him captured everyone's expressions and movements at a glance.

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

The person in charge of the office hurriedly responded to Liu Cheng and others. An ordinary medium-sized enterprise in Beijing still felt a little guilty when facing criminal cases and criminal police officers.

Jiang Yuan didn't care about these, and took Mu Zhiyang and moved along the aisle.

Wang Chuanxing followed behind to take pictures and recorded the whole process as evidence.

After all, the coverage of the police officers' body cameras is limited. When it comes to the level of a murder, it is always right to take more photos.

There are quite a lot of green plants in the office area of ​​this company. Each employee has a pot of green radish on the side of the aisle. The window sill area is also specially set aside to place some green plants, most of which overlap with the ones on the list, such as daffodils, phalaenopsis, red and white anthuriums, and Clivia...

Jiang Yuan found more than 30 types of pollen on the blood-stained clothes, of which there are almost 30 types with a large number. Most of them are common indoor green plants. It is normal to have duplications. However, the duplication rate of this company is already higher than the normal level.

Jiang Yuan frowned.

In terms of the concept of pollen atlas, this is a mismatch.

As for the pollen of some plants that were first contaminated at the company and then at home, the overlapping levels of the pollen are different. In other words, even if the pollen of two places far apart constitutes the same type, it does not belong to the same group of pollen maps due to reasons such as quantity and location.

Jiang Yuan went to see a few more small offices and conference rooms, and then returned to Liu Cheng and whispered: "Some flowers were not seen, but the ones that were seen were basically on the list, with a high repetition rate. We have to ask if there are other plants nearby and where these plants come from."

Liu Cheng was happy at first, and then frowned.

The most annoying thing for criminal police is this kind of thing that is a hair's breadth away.

If you are almost convicted, you will not be able to do a lot of things in vain...

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

This is a complicated question. Jiang Yuan said: "Ask first."

Liu Cheng then called the person in charge of the office into a conference room, opposite which was full of a row of policemen, and it was like a three-court trial.

The small manager of ordinary reputation had never seen such a thing before, and said cautiously: "We are a furniture company..."

"What do you ask you, you answer." Liu Cheng interrupted him with one sentence, and then said: "Who is taking care of these plants in your office?"

"Plants?" The person in charge couldn't guess what this was.

Liu Cheng said "hmm".

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

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

The person in charge seemed to have an answer and said hurriedly: "Yes, it is a green plant maintenance or green plant flower company. They bring a booklet and you can choose the flowers in it. There are also packages. After you have chosen, they will send the green plants over. 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 was opened in this way, it means that the client is not just this company.

Liu Cheng immediately said: "Give me the company name and contact information, and 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 while, and asked: "Has your company recently disappeared or has not come for several days?"

"No."

"Are all the staff present?"

"Yes, our company has full attendance." The person in charge said.

Liu Cheng said "um" 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.

After a while, the things Liu Cheng wanted were placed on the table.

Liu Cheng looked at the company address and found that it was in the suburbs. After hesitating for a while, he said, "Let's go directly to the door."

It is impossible to call to negotiate for clues of such a serious case. It is a small matter to be thought of as a liar by the other party. The only thing is to be afraid of alerting the snake and letting the murderer get away.

Jiang Yuan followed Liu Cheng without saying a word.

The suburbs of Beijing are quite far away, but Ningtai County Bureau often has to go to Xiangzhen to investigate cases. The journey is not necessarily farther, but it will only take more time.

Everyone entered the elevator quickly, leaving only two police officers to continue to register information and record statements.

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

Along the way, Liu Cheng was in a good mood. Compared with the previous lack of progress, this is more or less a clue.

Jiang Yuan closed his eyes and meditated throughout the journey.

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

Jiang Yuan was thinking about the various checks done in the laboratory at this time to avoid any omissions.

"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. Large tracts of farmland, green and lush, extended to the side of the mountain. Long and low white, black or blue greenhouses were concentrated in groups.

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

"If you kill someone here, you can just bury the bloody clothes in the ground. There is no need to go all the way to the city center." A criminal police officer next to him laughed.

Mu Zhiyang asked, "Provoking the police?"

"You... that's impossible. That's just a plot in a TV show. No one would feel uncomfortable with their own life and property." Liu Cheng said, but his expression became serious. If that was the case, the Zhengguang Branch would really have a shameless face.
