With the direction of investigation provided by Lin Shanshan, the crows quickly obtained the basic information of the deceased through visits to several large hospitals in the city.

The deceased's name is Ling Yunyan, 33 years old, unmarried. Before his death, he was an attending physician in the Department of Nephrology of the First People's Hospital of S City, and obtained a doctorate degree in medicine.

Ling Yunyan's approximate study and work experience is as follows: She graduated from City C Medical College in 1997 and was sent to graduate school because of her excellent grades.

In 1999, he obtained a master's degree and entered the Department of Nephrology of the First People's Hospital of S City in the same year.

In 2001, he published several papers in many academic journals at home and abroad, which attracted the attention of Professor Wilson of the University of Toronto. After several telephone exchanges with him, the professor decided that he was a malleable material, so he single-handedly urged the University of Toronto to send him an invitation to study abroad at public expense.

At the end of 2001, Ling Yunyan went to Ontario to study for a doctorate.

After receiving his Ph.D. in 2003, he declined Professor Wilson's offer to recommend him to Johns Hopkins Hospital, one of the top hospitals in the United States, and insisted on returning from the United States, hoping to apply what he had learned to serve his country.

At that time, several well-known hospitals across the country extended olive branches to him, but he still chose to return to S City and return to the First People's Hospital where he had worked for a while.

Since returning to China, he has been engaged in clinical work in nephrology. In clinical medicine, he is proficient in arteriovenous fistula surgery, peritoneal dialysis and tube implantation, renal pathological diagnosis, diagnosis and comprehensive treatment of rapidly progressive nephritis, comprehensive diagnosis and treatment of acute renal failure, and individualized dialysis treatment.

He is good at the clinical diagnosis and treatment of heart and kidney diseases, especially in the integrated treatment of refractory kidney disease, diabetic nephropathy, hypertensive nephropathy, lupus nephritis, chronic renal failure, etc., and is proficient in hemodialysis and colon dialysis.

In just a few years, in addition to publishing more than ten papers in national industry core journals, he has also participated in the compilation of several important monographs. In 2005, he won two provincial medical achievement awards.

In the investigation of the doctors and patients of the First People's Hospital of S City, it was learned that Ling Yunyan has a good reputation among his peers, he is low-key, thoughtful, and never hides himself in technology, and his leaders and colleagues have a very good evaluation of him.

Except that he feels like to be alone and doesn't often talk to everyone about other things other than work, there is nothing else special about it.

As for patients, Ling Yunyan not only often helps poor and critically ill patients financially, but also often helps them intercede with the hospital to delay or reduce part of their medical expenses.

Most of them said they had never heard of any arguments or quarrels with whom he had been, nor had they heard of him offending anyone.

In addition, during the investigation, it was also learned that Ling Yunyan's fiancée was Ni Xiaomei, the daughter of Ni Wannian, president of S City Xinya Group.

In 2005, Ni Xiaomei's grandmother was admitted to the city's first hospital due to hydronephrosis, and her attending doctor at that time was Ling Yunyan. Ni Xiaomei has a good relationship with her grandmother, and she often comes to take care of her grandmother, so she met Ling Yunyan, and after coming and going, the two fell in love.

I heard that the relationship has been very stable, and recently the two are preparing for marriage. And President Ni of Xinya Group, which has assets of hundreds of millions of dollars, is also very satisfied with this prospective son-in-law, and often asks Ni Xiaomei to take him home to play, and urges them to settle the marriage earlier.

Because Ling Yunyan's parents are in the countryside, and he likes to be quiet, he did not apply for a dormitory in the hospital, and has been renting a house at No. 1105, Building B, Friendship Building, after returning to China.

Recently, he purchased a 160-square-meter duplex house in the city's newly developed hot spring community, which is now being renovated and is ready to be used as a new house for his and Ni Xiaomei's wedding.

Since they had not yet received a decision on whether or not to announce Ling Yunyan's death to the outside world, they did not disclose his dead crow and Haizi to the hospital, so after investigating these basic circumstances, in order not to arouse the suspicion of others, they withdrew to the bureau and prepared to report to Yang Zi before taking further action.

On the other side, Yang Zi and Xiaopang went to the square for the second investigation, but it didn't go so smoothly.

The square was originally an open-air place open to the public, even if there were any clues missed at that time, after these few hours, coupled with the fact that the square deliberately arranged for someone to clean up the small area where the body was found, when Yang Zi and the others came again, not to mention the possible clues, even the large pool of dirty blood on the ground was washed away.

The two of them went to the cleaner who found the body again, and asked her to think carefully about whether they had found anything like medicine bottles, wine bottles, aluminum beer cans, etc., while cleaning the area around the body.

The cleaner thought carefully for a long time, shook her head and told them that she was not sure if there were any medicine bottles, and she had the impression that there were none, because the garbage they cleaned was usually sorted according to the requirements.

But she was sure that there were no bottles or aluminum beer cans in the garbage that had been swept out of this corner.

When Yang Zi and Xiaopang returned to the team, it was already early on, and before they knew it, it was already more than six o'clock in the afternoon. With the materials they had gathered, everyone sat around in a small conference room and conducted a preliminary analysis of the case.

The crow first said that he felt that this case was a suicide, probably because Ling Yunyan had something unspeakable or some depression, otherwise why there was no trace of anyone else at the scene.

When I apply for a search warrant from the bureau early tomorrow morning, I will definitely be able to find the suicide note where Ling Yunyan lives, and the truth will be revealed, and the case will be closed.

But Haizi thinks that from the current situation, Ling Yunyan has no motive to commit suicide at all, his career and love are both a double harvest, not only is his career in the period of rising and developing, but love is about to blossom and bear fruit, and his colleagues have a good evaluation of him, and he doesn't feel any contradiction with anyone, how can such a person commit suicide?

Xiaopang also rushed to say that at the scene where the body was found, no medicine bottles and wine bottles were found, since Dr. Lin found that Ling Yunyan had drunk a lot of alcohol and swallowed a large amount of diazepam before her death, there should always be traces of these two things at the scene, right?

It stands to reason that a person who wants to commit suicide cannot clean up the scene and throw the medicine bottles and wine bottles elsewhere before he dies. It is impossible to drink and take medicine somewhere else and then run here to kill himself, after all, the place where he lives is far from the square, and under the influence of medicine and alcohol, he should soon fall into a state of confusion.

The crow, the little fat, and the sea son each insisted on their own words, and the three of them argued red-faced.

At this time, Yang Zi, who had not spoken, was listening to their discussion and making notes in his notebook, suddenly said, "Let's get here first today." Chubby, you go and apply for a search warrant early tomorrow morning, and you and I will find a way to go to Ling Yunyan's place to take a look. Crow, you and Haizi go to check on Ni Xiaomei, and at the same time, the news of Ling Yunyan's death, the two of you can choose an appropriate time to reveal it to her and see her reaction. ”
