Chapter 619

Huilong Building.

This is an office building built in the early 2000s. From the perspective of that year, the standard was quite high, but looking at it today, it is somewhat outdated.

In terms of appearance, its curtain wall doesn't look as cool compared to the all-glass style, and it can't compare to the new material office buildings that follow the environmental protection route and are more expensive in the new era.

Walking into the building, the property management is also obviously lagging behind. Whether it is hygiene or the maintenance of equipment such as elevators, it shows an aura of old age, giving a feeling of a boys' dormitory building.

"This kind of office building shouldn't be for sale, right? Everyone is renting?" Liu Cheng observed the surroundings, looking a bit worried.

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

Jiang Yuan knew Liu Cheng's worry and comforted him: "At least the plants are there, so it's enough to confirm the identity."

Liu Cheng thought so too, and nodded: "Even if he uses a fake ID card, I reckon we can find out."

Renting this kind of office building at least requires providing an ID card.

And from the perspective of the police, for a general homicide case, becoming a fugitive pursuit can be considered half a failure. But this case is a headless case, and the difficulty of solving it is obviously high, so even if it becomes a fugitive pursuit, it's not a loss. Given the current environment in the country, unless the murderer hides in the deep mountains and old forests to hunt and fish for a living, completely abandons his mobile phone, has no contact with the outside world, and completely detaches from society, otherwise, it is very difficult to escape.

In terms of police force alone, if two or three people can be responsible for the pursuit, it is more than enough.

With this mental preparation, Liu Cheng didn't say much more. He stared at the elevator until it reached the 22nd floor, and then when he went out, he already had the demeanor of a great criminal police officer.

The entire 22nd floor was rented by a home furnishing enterprise. Liu Cheng first had people block the elevators and stairs for entry and exit before revealing his identity and entering with Jiang Yuan and the others.

The group of "white-collar elites" who were working looked at Liu Cheng and the others with sleep-deprived expressions. Like donkeys on a production team suddenly seeing people from another village, their hazy eyes lit up one by one, as if expecting something good to happen.

Liu Cheng and the camera behind him captured everyone's expressions and actions in full view.

If Jiang Yuan confirmed the species of the plants, these video materials could now be used as clues.

The person in charge of the office hurriedly dealt with Liu Cheng and the others. For an ordinary medium-sized enterprise in the capital, facing criminal cases and criminal police officers, they were still a bit guilty.

Jiang Yuan didn't need to worry about these things. He took Mu Zhiyang and moved along the aisle.

Wang Chuanxing followed behind taking pictures, with full video recording as evidence.

The coverage of the law enforcement recorders on the chests of the police officers was limited after all. When it reached the level of a homicide case, there was nothing wrong with taking more materials.

In the office area of this enterprise, there were quite a few green plants. Every employee had a pot of pothos placed on the side near the aisle, and the windowsill area was also specifically set aside to place some green plants, most of which overlapped with the list, such as narcissus, butterfly orchid, red anthurium, white anthurium, clivia...

Jiang Yuan found more than thirty types of pollen on the bloody clothes, and there were nearly thirty types with large quantities. Most of them were common indoor green plants, and it was normal to have overlaps. However, the overlap rate of this company was already higher than the normal level.

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

In terms of the concept of pollen spectrum, this belongs to a state of mismatch.

As for saying that one was contaminated with pollen from certain plants at the company, and then contaminated with pollen from certain plants at home, the overlapping layers of pollen are different. That is to say, even if the pollen between two places far apart forms the same species, because of the quantity, location, and other reasons, they do not belong to the same set of pollen spectrum.

Jiang Yuan went to look at a few small offices and conference rooms, then returned to Liu Cheng's side and whispered: "There are some flowers I haven't seen, but the ones I have seen are basically on the list. The overlap rate is very high. I need to ask them if there are any other plants nearby, and the source of these plants."

Liu Cheng was happy at first, and then his brows wrinkled.

For a criminal police officer, the most annoying thing is this kind of "a miss is as good as a mile" situation.

If it's off by a little bit, you can't convict, and doing a bunch of things is equivalent to doing nothing...

"Then is it here?" Liu Cheng had to ask one more question.

This is a complex question. Jiang Yuan said: "Let's ask first."

Liu Cheng then called the person in charge of the office into a conference room, with a row of police officers sitting opposite, in the posture of a joint trial.

Where had a small manager of ordinary fame seen this? He said cautiously: "We are just a furniture enterprise..."

"Answer whatever I ask you." Liu Cheng interrupted the other party with one sentence, and then said: "Who takes care of these plants in your office?"

"Plants?" The person in charge racked his brains and couldn't guess what kind of approach this was.

Liu Cheng said "Hmm."

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

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

As soon as the person in charge saw that there seemed to be a solution, he hurriedly said: "Yes, it's a green plant maintenance or green plant flower company. They bring a booklet, and you can choose the flowers inside, and there are also packages. Once chosen, they send the green plants over, and they are also responsible for daily maintenance. We don't need to worry about it. Even if the flowers die, they take them back themselves and replace them with new ones."

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

Since the company is operated in this mode, it means that the customers are not just this one company.

Liu Cheng immediately said: "Give me the company name and contact information, and also, your contract with the other party."

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

"Also." Liu Cheng called the other party again, pondered for a moment, and asked: "Has anyone in your company gone missing recently, or any employees who haven't come for several days?"

"No."

"Everyone is here?"

"Yes, our company has 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.

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. He hesitated for a moment, but still said: "Let's go directly."

For clues to such a major case, it is impossible to negotiate over the phone. It's a small matter if the other party thinks you are a liar, but the fear is alerting the enemy and letting the murderer get away.

Jiang Yuan also followed Liu Cheng without a word.

The suburbs of the capital are quite far, but the Ningtai County Bureau often has to run to the townships to investigate cases, and the distance is not necessarily farther, it just takes more time.

The crowd brushed into the elevator, leaving only two police officers to continue registering information and taking statements.

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

Along the way, Liu Cheng's mood was not bad. Compared to having no progress before, this was more or less a clue.

Jiang Yuan was closing his eyes and thinking throughout the whole journey.

At present, the case is being investigated based on forensic botany, but in terms of the current configuration of the special task force, Jiang Yuan is the only one who can understand forensic botany. In other words, the information is all provided by Jiang Yuan, so he is the only one who can be held responsible.

Jiang Yuan was thinking about the various examinations 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 someone." Liu Cheng got out of the car and looked around. Large tracts of farmland extended to the mountains, and long, low white, black, or blue greenhouses were concentrated in clusters.

Liu Cheng stretched and said: "The sky is high and the emperor is far away, there is no surveillance, and it is close to the roadside. There are water pipes and canals, and the ground is still dirt. Killing someone here, the blood can be washed directly into the canal, which is convenient."

"If you kill someone here, you can just bury the bloody clothes in the ground. There's no need to throw them in the city center from thousands of miles away." A criminal police officer next to him laughed.

Mu Zhiyang said: "Provoking the police?"

"You... this is impossible. Those are all plots in TV dramas. Where would anyone use their own life to find trouble?" Liu Cheng said, but his expression became serious. If that were really the case, the Zheng Guang branch would really have a face it couldn't afford to lose.
