A male body was found in a residential tap water tank in Sanhe County, judging from the circumstances of the case and various clues, this is a serial homicide case, which can be investigated together with the murder of Xu Yufen.

Moreover, according to the preliminary autopsy investigation of Ren Qiushi, chief of the forensic department of the Ningzhou Municipal Public Security Bureau, the time of death of the deceased Liang Dongsong in this case should be before Xu Yufen.

This also shows that in this serial murder case, Liang Dongsong is the first deceased, and Xu Yufen is the second deceased.

However, these are still speculated so far, and everything will have to wait for the autopsy to be carried out, and the autopsy report shall prevail.

The deceased was followed by the murderer and killed after opening the door and entering the house, the murderer did not enter the room, and there was no sign of the door being damaged.

"It's a retired obstetrics and gynecology staff member from Sanhe County People's Hospital, and it seems that I should go to the hospital to check." I froze and muttered.

Subsequently, I assigned the members of the Serious Crime Team the following tasks:

Zifan, cooperating with the police officers of the Sanhe County Public Security Bureau, launched an investigation from Liang Dongsong's social relations.

Xue Hang was responsible for investigating the surroundings of the crime scene, obtaining surveillance, and visiting neighbors to see if there were any suspicious people at the time of the crime.

Old dog, conduct a careful on-site investigation of the scene of the dumping of the corpse and the scene of the crime, this time the place of dumping the corpse is not at the scene of the crime, to see if any clues can be found along the road.

Li Meng, follow me to the investigation of Sanhe County People's Hospital. ”

The autopsy at the scene has been completed, and the body has been carried onto the corpse truck, and Ren Qiushi and Zeng Lan from the forensic department will return to the Ningzhou City Public Security Bureau with the team to conduct an autopsy of the body.

The location of the crime this time is not far from the Sanhe County People's Hospital, and I have checked this direction according to the map before I came.

Driving the civilian police car provided by the county public security bureau, Li Meng and I went to the Sanhe County People's Hospital together.

As a person who doesn't have a girlfriend yet, I came to the obstetrics and gynecology department for two days in a row, and I always felt weird in my heart.

Because I had just been here once yesterday, I was familiar with the road, and walked directly into the elevator with Li Meng and pressed the button on the sixth floor.

There are a total of four elevators in this hospital, and the two elevators opposite only stop on odd-numbered floors, while the elevators we are taking now and the elevator next door only stop on even-numbered floors.

The elevator still has the doctor's identity information, and the elevator I took yesterday was the information of Yang Fan, the director of this hospital.

"Daytime pigeon, that's a nice name." Li Meng looked at the information display board on the wall and muttered.

Hearing her voice, I also looked towards the information board on the wall.

Bai Pigeon, attending physician of the Department of Obstetrics and Gynecology.

Below is a brief introduction about the White Pigeon, including which medical school she graduated from, her qualifications since she started her career, and a bust photo of her alongside it.

After a while, the elevator rang, two doors slowly opened, and I was once again in the obstetrics and gynecology department on the sixth floor.

We still use the most familiar method of investigation cooperation, I go to the management, she goes to the staff.

Stepping out of the elevator, I turned left directly in the T-shaped corridor and walked towards the nurse's station on the left, I learned about Xu Yufen's situation from the head nurse Jiang Rou yesterday, and this time I was still ready to continue to ask her about the situation.

I had just arrived at the nurse's desk when I heard the sound of hurried footsteps behind me, and I was about to turn around to look back when a pink figure flashed past me.

It was a nurse in a pink nurse's uniform, and she walked past me nervously, straight into the doctor's office on my right.

She walked straight up to a doctor who was sitting behind a computer that was blocking the doctor's body and I could only see one of his arms.

"Doctor Bai, the caesarean section patient on Bed 23, has a cracked incision, has developed redness and swelling, and a small amount of discharge is out." The female nurse said seriously.

"It may be that the fat of the incision is liquefied, and the secretions from the incision area are taken for bacterial culture and drug susceptibility test, and the incision part should be changed every day. If there is a bacterial infection in the culture of the secretion, anti-inflammatory treatment with antibiotics that are insensitive and can be used during lactation should be chosen. The doctor spoke.

Judging by the voice, the doctor is a woman, and the nurse calls her Doctor Bai, who should be the daytime pigeon doctor we saw in the elevator.

The female doctor filled in the medical record on the table for the next treatment plan for the patient, then stood up and said, "I'll take a look." ”

The female doctor stood up, and then I could fully see her appearance, she was the day pigeon.

She is an attending physician in the Department of Obstetrics and Gynecology, and I am going to find her to investigate the situation later, which is estimated to be more reliable than looking for Jiang Rou, the head nurse.

The pigeon came out of the doctor's office and habitually tucked the gel pen into her breast pocket, and after one look at me, she walked straight to the ward.

I leaned back on the nurse's table a little bored, quietly waiting for her to come back.

"Officer Qin?"

Suddenly, a familiar voice came from behind him.

When I turned around, Jiang Rou, the head nurse, walked towards me.

I smiled at her.

"Is Officer Qin still here to investigate Xu Yufen?" Jiang Rou walked into the nurse's table and asked me softly.

I shook my head and said with a smile: "No, I'm here to ask Liang Dongsong today." ”

"Dr. Liang?" Jiang Rou was stunned and looked at me with some puzzlement.

"Yes, are you familiar with him?" I nodded and asked seriously.

"It's familiar, he's been retired for several years, what do you want to ask?" Jiang Rou looked at me very puzzled, and it was not difficult to see from her eyes that she was very curious now.

She was wondering why I was so interested in retired doctors and nurses in obstetrics and gynecology.

"How's Dr. Liang going?" I spoke slowly and asked a more general question.

"How's the people?" Jiang Rou was stunned for a moment, and then said lightly: "Others are very good." ”

I pondered for a moment, then asked her a different question: "How is the relationship between Liang Dongsong and Xu Yufen?" ”

"Their relationship is also good, the two of them are seven years apart, one is the deputy chief physician, the other is the chief nurse, and there are frequent exchanges at work. And I also heard that they seem to be old acquaintances, and it seems that they knew each other before they came to work at Sanhe County People's Hospital. I guess they graduated from the same medical university. Jiang Rou looked at me and said slowly.

I frowned suddenly, and asked again: "You said they knew each other before they came to work at Sanhe County People's Hospital?" So which hospital did they work in before? ”

Jiang Rou shrugged her shoulders slightly, and whispered to me: "I don't know about this, I came later, and these are all things I heard, and I don't know the specific situation." ”

I nodded, and after a momentary change, I asked him again, "How long has Dr. Pigeon been working here during the day?" ”

"Doctor Bai, she has also been working for a long time, probably seven or eight years." Jiang Rou said lightly.

"Seven or eight years of work?" I asked, a little puzzled.
