At about 8 p.m., the three accountants arrived at the Municipal Bureau one after another and entered three interrogation rooms respectively.

Fu Da, Du Zhun, and Liu Feng each brought one person to conduct the interrogation.

Twenty minutes later, the three entered Tan Yi's small office together.

Tan Yi asked: "How is it, what did you say?"

Fu Da said: "First, there is no tax evasion, the accounts are clear, and they can definitely withstand investigation; second, Gao Caiwen has a cleanliness fetish, and he brought the rag. Gao Caiwen said that the plastic bag was placed under the rag and was reserved for garbage. Cao Lushi's death had nothing to do with him; third, they and Cao Lushi were just ordinary superiors and subordinates. Some situations can be asked to the cashier Guan Wei, she knows more."

Tan Yi picked up the cigarette box, took out a cigarette, and pushed it to Fu Da again.

Fu Da took three cigarettes and gave one to Liu Feng and Du Zhun.

Tan Yi pressed the lighter and took a puff of the flame, "Then please Guan Wei."

Du Zhun put the cigarette behind his ear, "I'll take a walk."

He went out.

Fu Da and Liu Feng sat down on the chairs in front of the desk.

Fu Da said, "Generally speaking, the relationship between the cashier and the factory director is good. There are rumors in the machinery factory that this Guan cashier is Chen Zhicheng's mistress."

Liu Feng flicked the ashes, "This matter has been going on for a day, will the person run away?"

Fu Da said, "Maybe."

Tan Yi understood what the two meant - in the end, the murder of the chief financial officer was mostly related to the accounts and working capital, and these two things were inseparable from the factory director.

According to his observation, although Chen Zhicheng concealed himself well, he could still see his anxiety.

Was he really the mastermind?

Not necessarily.

If he was the mastermind, he should not have appeared in the machinery factory that night.

He suddenly remembered what Xie Qing told him when he was at Grandpa Ken's, about the conflict between Chen Zhicheng and Deputy Director Liu.

So, could it be that Deputy Director Liu framed him?

He said, "If Guan Wei really ran away, then Chen Zhicheng would be a big suspect. Chen Zhicheng would not be that stupid."

Fu Da nodded thoughtfully, "That makes sense, but no matter what, the accounts of the machinery factory will have some problems, big or small. If she doesn't leave, she may think she has the strength to fight."

...

An hour later, Fu Da and Li Ke appeared in Guan's inquiry room.

Guan was 31 years old, with an oval face, red eyes, beautiful appearance, and a plump figure. She looked like a delicate and gentle girl.

Fu Da asked, "Captain Guan, you have a good relationship with Cao Lushi, right?"

Guan Wei lowered her eyes, "He is the leader and I am the subordinate, so our relationship is indeed good."

Fu Da said, "In terms of work, has he ever asked you to do anything that violates financial regulations?"

Guan Wei shook her head, "Of course not. Even if he asked, I couldn't do it. Our factory director said that I am in charge of the purse and there must be no mistakes."

"I heard that you have a good relationship with Factory Director Chen, is that true?"

"No, absolutely not. People in the factory are like this. If they see that you are pretty, they will make up stories about you and your relationship with you. Director Chen and I are innocent, just like the police officer and this female police officer."

Fu Da immediately felt that this cashier was unusual. He smiled and changed the subject. "I heard from several accountants that Section Chief Cao had thoughts of suicide. You often drink and sing together. Have you heard him talk about this?"

Guan Wei raised her hand and stroked her hair. "Not only have I heard it, but I have heard it more than once or twice."

Fu Da asked: "Why do you think he had thoughts of suicide?"

Guan Wei said: "I heard that his wife is not a good person. She controls him like a grandson. He must be living a very depressed life."

"He wrote a letter of resignation before he died. Don't you think his death is related to his work?"

"How could that be? We were the ones doing the work, and he just had to check. It wasn't that tiring."

This guy not only played dumb, but also changed the subject.

Fu Da said, "Where were you on the night when Section Chief Cao got into trouble?"

Guan Wei said, "Of course I was at home. I helped my kids with their homework, then washed up and went to bed at 9:30. Officer, you don't think I killed Section Chief Cao, do you? Oh my God, how could that be possible? I have a good relationship with him, and we often go out together."

She looked at Fu Da with wide eyes, and her shocked expression looked like that.

Unfortunately, Fu Da didn't believe a word she said.

"Has Chief Cao ever worked overtime before?"

"Rarely, at most once a month, and he's with everyone."

"Who does he have a bad relationship with?" "

Our department? They're all fine, except Lao Zhang and Li Zao Zhang. He says a lot of weird things, but it's impossible that he would kill someone because of that, right?"

"Okay, that's all for today. Thank you, cashier."

"Don't be polite. We're law-abiding citizens. Just ask whatever you want."

"Okay, it's best not to go on business trips these days. We may need to continue to ask you some questions."

"No problem, our cashier rarely goes on business trips."

Guan Wei walked out of the inquiry room gracefully in high heels and carrying an exquisite small purse.

Li Ke packed up his notebook, "Looks delicate and gentle, but actually has a sly heart, really extraordinary."

Fu Da praised, "Xiao Xiao has made progress."

Li Ke pursed his lips, "Who are you criticizing, Brother Fu?"

Fu Da smiled slightly, "You have really made progress this time, Xiao Xie is a little scorpion spirit, you will slowly transform into a little fox, but you must not become a spirit."

Li Ke was so angry that he fell backwards and stomped his feet out.

When they returned to the second floor, almost all the members of the second group had returned.

Tan Yi asked Li Ke to call Xie Qing - if she was in the dormitory, let her come back for the meeting, if she was at home, forget it.

When Xie Qing received the call, she was practicing boxing in the training room, sweating all over her face.

She took a towel, went to the bathroom to quickly clean herself up, and then hurried to the meeting room of the Second Brigade.

Tan Yi presided over the meeting and wrote a few names on the blackboard. The names of the four factory managers, all the financial staff, and the security guard on duty that night were all listed.

Tan Yi lit a cigarette, "Today is Sunday, but everyone has worked hard all day. I will treat everyone to barbecue after the meeting."

"Oh..." "

Thank you, Captain Tan!"

"That's great."

"Captain Tan, I think I can still hold on."

"Hahaha..."

...

The dullness was swept away by the imaginary barbecue aroma, and the atmosphere became lively.

Tan Yi said: "If the murderer is cunning, the case will not be simple. The names on the blackboard are all key targets for investigation. Don't think that someone is the most suspicious and be careless about other people."

"In addition, considering that the murderer used extreme means to force the deceased to take medicine and commit suicide, it is speculated that there is a high probability that there is a gun, so there is an 80% chance that it involves buying a murderer. If this is the case, everyone must pay attention to their own safety."

"Brother Fu, tell me about the investigation of the tranquilizer pills and the investigation of the suspects."

Fu Da raised his chin towards Li Ji.

Li Ji said, "Today I went to four hospitals, all the pharmacies near the hospital, the machinery factory, and Cao Lushi's home. I got confirmation from the city hospital and four clinics that Cao Lushi bought a total of four bottles of Valium."

Du Zhun sat up, "Isn't that still suicide?"

Fu Da said, "Stop talking nonsense, it only proves that he had such an idea."

Du Zhun collapsed again, "That's right."

Li Ji said, "I think if the murderer forced him to commit suicide, then it's obvious that the victim was killed by someone he knew."

Li Ke objected to his opinion, "That's not necessarily true. The mastermind must be someone he knew, but the murderer may not be."

Fu Da looked at Tan Yi, "This is the only difficult thing now. No one has seen anyone go to the third floor. Old Li is a chicken thief. He just probed a little bit. If he finds that it doesn't work, he will ask us for support."

He said it was Li Yusen from Feng'an Branch.

"Really."

"It's not just one or two days."

"Whenever there is dirty work or hard work, he uses us as a shield."

...

It would be better if Fu Da didn't mention it. Once he mentioned it, everyone would be full of complaints.

In the same system, there are mostly no secrets, because you don't know who is talking nonsense.

Tan Yi did not agree. He pointed at the names on the blackboard and said, "Have you figured out their backgrounds? Especially the security guards, have you checked their patrol routes and time points?"

Fu Da flipped open the notebook and said, "They work in three shifts, with six people in each team, four on the periphery and two inside. The four outside have all served in the army, while the two inside are older, one has served and the other has not." "

The two inside said that at 7 p.m., they, led by the office director, walked around each floor and went to the factory area when they found no safety hazards. During this period, there were no security guards in the office building. Basically, only Director Chen and the deceased were there."

"They said they knew Section Chief Cao was there, but they didn't disturb him."

Xie Qing wrote this down and tapped "nineteen" with her pen. She thought to herself that this was an important time node. After all, Chen Zhicheng was the biggest suspect.

But she agreed with Tan Yi's opinion. Under the premise that there were no threatening injuries on Cao Lushi, it must be considered that the murderer had a gun. In this case, the case would not be as simple as it seemed.

Maybe the murderer just wanted the police to focus on Chen Zhicheng.

After listening to the reports from all sides, Tan Yi summarized the key points as follows:

1. The mastermind is an acquaintance of the deceased.

2. Guan Wei and Chen Zhicheng are major suspects. Investigate their financial situation and private relationships, and check the registration status of major hotels in the city.

3. The staff of the Finance Department did not tell the truth, and further work needs to be done, especially Accountant Li Zaozhang, who had a bad relationship with Cao Lushi.

4. The deceased's wife Wang Haiya behaved suspiciously, and her financial situation needs to be further investigated.

5. Several deputy factory directors cannot sit idly by, especially Deputy Factory Director Liu.

6. This case may involve organized crime and economic cases, and it is necessary to communicate well with the Economic Investigation Detachment and the First Brigade.

Finance is the core department of an economic entity, involving many people and things.

The more complicated the relationship, the greater the workload of the police.

After everyone discussed the focus of the work, it was half past nine, and the group left the conference room and prepared to go to the barbecue restaurant.

It was impossible not to go to the toilet in a meeting that lasted more than an hour.

Li Ke took Xie Qing to the third floor.

She whispered, "These guys don't care about anything. The smell after using the toilet is enough to drive people away. The edge of the squat toilet is sticky. Why don't they mind?"

Xie Qing said, "Men are rougher. Maybe they are used to it. In fact, urine..."

She suddenly paused.

In fact, public toilets in offices are almost the same. There will always be people who pee on the edge. People who like to be clean will check whether the edge is clean before going to the toilet.

Cao Lushi is an old employee of the machinery factory. He went to the toilet calmly and stepped on it?

This is not normal.

Could it be that someone pointed a gun at his head and he was so scared that he pulled to the edge and accidentally stepped on it when he was forced out?

In order to cover up the truth of his murder, the murderer had to mop the floor and clean his shoes?
