Li Yusen walked to Tan Yi's side and observed the manuscript paper in his hand. As expected, he found a lot of marks on the first line. After a little identification, he could see that it was indeed the four words "Resignation Report".

He said: "Captain Tan, we have searched carefully and did not find this resignation letter. Could it be that he wrote it in the past and tore it up after writing it, and then he never had the opportunity to use this manuscript paper?"

This speculation makes sense.

Tan Yi said: "Keep your doubts for now, and confirm it when you ask his colleagues and family members."

Xie Qing thought that the manuscript paper was on the table, and it should have been used recently or before death. Otherwise, there were a lot of accounting books, and the deceased would not put things that he would not use on the table. While

she was thinking, she and Han Feng lifted the body onto the stretcher and handed it to several grassroots police officers to carry it out.

There were a few strands of hair on the bed, similar to the hair of the deceased. Xie Qing picked them up one by one, put them in the evidence bag, and handed them to Fu Da.

Xie Qing followed the stretcher downstairs. As soon as she walked out of the door, the woman in black started crying, "Lao Cao, Lao Cao..."

The woman only called twice, rolled her eyes, and fainted.

The people behind her supported her in time, pinched her Ren Zhong, rubbed her chest, and she woke up before Xie Qing was ready to go over to rescue her.

Han Feng said, "Let's go, so as to avoid complications."

Xie Qing nodded and got into her car.

Han Feng followed and sat in the passenger seat. "I heard that the city bureau has solved several major cases recently."

Xie Qing said, "You are well-informed."

Han Feng smiled and said, "The case has a huge impact. Besides, there are no secrets among colleagues."

Xie Qing said, "That's true."

...

More than forty minutes later, Cao Lushi's body was placed on the dissection table.

After removing the clothes from the body, the two examined it again.

The top was a new camel-colored jacket with nothing in the two slanted pockets. The inner shirt was a white shirt, very clean, without any traces of ink, and there was a brand-name fountain pen in one side pocket.

Xie Qing picked up the shirt and compared each button carefully. "The buttons at the collar are slightly loose."

Han Feng said, "Isn't it normal for the buttons at the collar to be loose?"

Xie Qing turned over the collar. "It's Geya, a good brand, 80% new, it shouldn't be loose."

Han Feng asked, "What are you suspicious about?"

Xie Qing gestured with her hand. "I'm wondering if someone forced him to swallow these tranquilizer pills."

Han Feng thought about it and said, "It's not impossible."

He was wearing a pair of navy blue wool trousers. There was a little change in the right pocket, but nothing else.

His leather shoes had been wiped clean inside and out.

Han Feng said, "He is dressed very neatly, even his shoes are polished. This person is quite particular."

Xie Qing took the photo, looked at the soles for a long time, and said quietly, "Doctor Han, don't you think the soles are too clean?"

A person who loves cleanliness may polish the surface of the shoes, but who would polish the soles so cleanly?

Han Feng didn't pay much attention to this at first, but he came over after hearing this. He saw that there were only one or two small stones in the gaps of the pattern on the soles, and the rest of the shoes seemed to have been wiped with a rag.

He said, "It is indeed a bit suspicious, but we cannot rule out the possibility that the deceased wanted to leave cleanly, so he took care of everything."

Xie Qing nodded, "This explanation is also reasonable, but I reserve my opinion.

...

The deceased had delicate features, a medium build, a slightly bulging abdomen, and obvious signs of weight gain.

Han Feng performed the operation, cutting open the skin and subcutaneous tissue... opening the chest and abdominal cavity to expose the dirty organs.

While Xie Qing was using a camera to record the evidence, he said, "The internal dirt, blood congestion, and edema are obvious."

Han Feng took out the heart and lungs in turn, "There was no punctate bleeding on the surface."

Then he opened the bronchus, which contained a small amount of white foam.

He said, "These characteristics are consistent with the signs of a corpse poisoned by diazepam. "

Xie Qing cut open the stomach of the deceased with a few scissors and opened it. A strong smell of alcohol hit her nose. She held her breath and scooped out some of the stomach contents with a spoon and placed them in a transparent container.

There were still many undigested pills and drug powders in the stomach, and there was no food residue at all.

Han Feng frowned, "The deceased ate first and then committed suicide. This is normal, but how could there be so many drug residues?"

Xie Qing said, "Don't panic, we will know after the test, let's take a look at the lungs and neck."

There was no drowning fluid in the lungs, and no bleeding in the subcutaneous fat of the neck.

Drowning and strangulation can be ruled out.

Xie Qing took samples from the liver, "He has obvious signs of alcoholic fatty liver. "

Han Feng groaned, "In this position, socializing is unavoidable."

If financial personnel often eat and drink with others, the possibility of corruption will be greatly increased.

It is reasonable for the deceased to commit suicide or be killed by others.

The two sorted out the autopsy report and took the samples back to the Municipal Bureau, which was tested by the Municipal Bureau's technical laboratory.

Then they returned to the Feng'an Branch from the Municipal Bureau to participate in the case analysis.

When the two arrived, the meeting had already begun.

Li Yusen was introducing the case.

According to the old Li in the communication room, the deceased returned to the office building yesterday evening, holding a plastic bag in his hand, with an ugly face, but also politely greeted him.

After people went to the office, the lights were on and were not turned off all night.

Old Li said that it was normal for people not to leave and lights not to be turned off, so he did not go upstairs to check. It was not until

his wife came to him early in the morning and said that Cao Lushi had not returned home and asked to go to the office to look for him.

Old Li notified the security guard to accompany him and went upstairs together.

The security knocked on the door several times, but no one answered. When he turned the door handle, he found that it was not locked. He asked his wife to wait outside for a while, and he went in to check, and then he found that the person was dead.

The security guard was a retired soldier in his thirties. He had received training in this area and knew that he could not destroy the scene. After going out, he told his wife the news and called his colleagues to protect the scene with the intercom.

Cao Lushi graduated from college with a major in accounting. He was assigned to work as a cashier at Fuguang Machinery Factory right after graduation. Because of his serious work and warm-hearted attitude, he quickly gained the trust of the former chief of finance.

After the old chief retired, he was promoted by Chen Zhicheng, the factory director of the machinery factory, to become the chief. From then on, he was like a fish in water and became a popular figure in the factory.

Cao Lushi has seven people under him. Three accountants work in the same room with him, and the remaining three work in a small office next door.

According to the three accountants, they didn't know that Cao was going to resign, but Cao had been listless recently and had severe insomnia. It was said that he had been prescribed sleeping pills at the hospital.

As for why he had insomnia, his colleagues said they didn't know.

An old accountant named Zhang told them that Cao Lushi didn't care about the people above him, and their relationship was average.

The case officers interviewed Chen Zhicheng and the factory leaders, who all said that Cao Lushi was rigorous in his work and rarely made mistakes. They did not know why he was so depressed.

His wife Wang Haiya firmly believed that Cao Lushi did not commit suicide.

She said that Cao Lushi did not like socializing every day and said that he would submit a resignation report on Monday. It was impossible for him to commit suicide.

This was basically consistent with Tan Yi's judgment.

But as a middle-aged man and a mid-level cadre, Cao Lushi suddenly wanted to resign from a well-paid and glamorous state-owned enterprise. This was incomprehensible no matter how.

Li Yusen then questioned Cao Lushi about corruption and dereliction of duty.

Wang Haiya denied it outright, and colleagues in the finance department and the factory director Chen Zhicheng did not agree with it.

As for other factory leaders, they all said that the Finance Department was in charge of Chen Zhicheng, and they knew nothing and declined to comment.

After Li Yusen finished explaining the case, his colleagues from the Trace Inspection Department made a report on the trace inspection.

There were no footprints in the office - because it was raining, the security guard was patrolling inside the building and did not go out.

There were no signs of prying on the doors and windows of the office. The fingerprints on the door and door handle were mixed, and the clearest one was the security guard's fingerprint.

There are usually three to five fingerprints on the bottle of tranquilizer tablets. In addition to the deceased's, the remaining fingerprints are speculated to be from a drugstore or hospital pharmacy, and further verification is needed.

After the trace inspection, it was the forensic doctor's turn.

Han Feng said, "The autopsy is consistent with the general characteristics of valium poisoning, but there are more tablets left in the stomach. The samples have been sent to the technical room. Further tests such as blood and liver are needed to determine the concentration before further judgment can be made."

Li Yusen asked, "Have you found other means of death?"

Han Feng shook his head, "Not yet."

Li Yusen looked at Tan Yi in embarrassment, "Captain Tan, the family is still waiting, what should we do?"

Tan Yi said, "To infer whether a person committed suicide or was murdered, a scientific verification process is needed. We just tell the truth."

"Okay then." Li Yusen sighed, "Xiao Han, you and Xiao Xie should go together later. Female police officers are better than men in communicating with female victims."

Xie Qing thought, she was just afraid of taking responsibility, so she dragged the people from the Municipal Bureau to act together.

In theory, she could disobey his orders, but he was of high rank and old, and not going with him would be a lack of face.

Xie Qing didn't look at Tan Yi and agreed directly.

Tan Yi said, "From Wang Haiya's confession, the possibility of the deceased committing suicide is indeed small, and his resignation is not in line with common sense. No matter what the forensic results are, everyone should conduct an in-depth investigation and sorting out of Cao Lushi's social relations. Captain Li, what do you think?"

Li Yusen said, "That's the truth, but if it's really suicide, we're making a fuss and making a fool of ourselves."

Tan Yi said, "If it's really murdered, we'll miss the opportunity and watch the evidence disappear." Li

Yusen was stunned for a moment, "That's right. I'll report to the higher-ups and prepare to find professionals to check the accounts. You guys divide the work and conduct further investigations on Cao Lushi's colleagues and relatives to see if he has other abnormal behaviors. Let's take action now."

The meeting was adjourned.

Xie Qing and Han Feng went to the reception room, and Fu Da and Tan Yi also came down together.

Fu Da said: "If there are no signs of death by other means on the body, then someone forced the deceased to take these sleeping pills. Could it be that the murderer had a gun?"

Tan Yi nodded, "This possibility cannot be ruled out."

Fu Da complained: "But it is difficult for us to find evidence to prove this. It's really troublesome!"

Xie Qing nodded. If it was really a case, the murderer must have certain anti-detection capabilities.

Han Feng said: "Brother Fu is too pessimistic. Cao Lushi wants to resign, which proves that his mental state is not good. Maybe he is committing suicide."

Tan Yi took out a pack of cigarettes from his bag, frowned and lit one, "He wants to resign, which does show that his mental state is a bit bad to some extent, but resigning is a way of self-help. Suicide at this time is more suspicious."
