After questioning the two maintenance personnel of the water company where the bodies were found, I got up and walked to Ren Qiushi and Zeng Lan on the side.

After the criminal police squadron of the county public security bureau received the alarm, they came to the scene of the crime as soon as possible and carried out the salvage work of the body.

Fortunately, the weather is not bad today, and we came in time, and the body is basically still the same as when it was found.

It was an elderly male corpse with the deceased completely naked. In order to prevent contamination of the mud on the rooftop, the police in Sanhe County spread a body bag under the body.

The water on the corpse had evaporated dry, and he was curled up and lying on his side in front of us.

Looking at this, I chuckled in my heart, because the posture of the corpse was exactly the same as the body of Xu Yufen that we found yesterday.

Forensic doctor Ren Qiushi and forensic assistant Zeng Lan are conducting preliminary autopsies at the scene.

"The cadaver temperature is low, the skin is pale, which is very noticeable due to the constriction of blood vessels caused by low water temperature. The color of the corpse spots is pink, and the HbO2 (oxyhemoglobin) caused by low water temperature is not easy to decompose, and the oxygen in the water penetrates into the blood vessels, resulting in a higher concentration of HbO2.

The skin on the body surface of the corpse has different degrees of epidermal cuticle maceration, whitening, swelling, and wrinkles, and the hands and feet are the most obvious, and the skin maceration is very severe.

The corpse spots are all concentrated on the left half of the deceased's body, which indicates that the deceased has been lying on the left side of the body after being killed and sunk. ”

After Ren Qiushi described the surface signs of the corpse, he examined the mouth and nose of the deceased.

"No mushroom-like foam was found in the mouth and nose of the deceased, and there was no life reaction, which indicates that the deceased was killed and sunk into the tank. The zombie is very obvious, but there are no obvious signs of giantism, the water in the tank is tap water, and it is early spring, and the water temperature is very low, and it is impossible to tell the specific time of death from the body surface of the corpse. ”

After Ren Qiushi finished speaking, he began to look for the fatal wound.

There were no obvious external injuries on the body surface of the corpse, and Ren Qiushi first reached out to wipe the deceased's head.

The deceased's entire skull had been deformed, and black and white hair swayed from side to side on the collapsed scalp. There was no other trauma to his body, and it can be concluded that he died of severe head injury, judging from the fracture line, the tool that caused the injury was still a blunt instrument like a strip stick.

"Section Chief Ren, look, surgical knot!" Zeng Lan suddenly spoke.

After examining the fatal injury, Ren Qiushi set his eyes on the deceased's body.

The deceased was curled up on his side, and everything was the same as Xu Yufen, his wrists, knees and ankles were sutured with medical sutures, and they were tied with very standard and beautiful surgical knots.

"It can already be determined that it is a serial murder case, and I estimate that this deceased should have died before Xu Yufen." Ren Qiushi said lightly.

All of this was heard by me standing beside me.

Sure enough, what we feared the most happened anyway, it was really a serial murder case.

Yesterday was found the body of a middle-aged and elderly woman, and today it was found that the body of a middle-aged and elderly man was found.

The situation of the two corpses has a high degree of overlap, the only difference is that the middle-aged and elderly male corpse in front of me does not have the wound cut by the sharp blade after all.

"This is definitely not the scene of the first crime, there is no blood at the scene, and no clothes on the deceased have been found, have you found the scene of the first crime?" Ren Qiushi settled down and suddenly asked me.

I was a little embarrassed to ask this question, because not only did I not find the first crime scene, but I also did not even determine the identity of the deceased.

But one thing is certain, the murderer chose to dump the body here, and the first crime scene must have been near here.

Fortunately, after a while, Jiang Ke, the criminal police captain of the Sanhe County Public Security Bureau, walked up to me: "Team Leader Qin, the identity information of the deceased has been confirmed. The deceased's name is Liang Dongsong, 69 years old this year, who used to work in the obstetrics and gynecology department of Sanhe County People's Hospital. ”

"It's obstetrics and gynecology again, yesterday it was a female nurse in obstetrics and gynecology, and today it is a male doctor in obstetrics and gynecology." I muttered.

In fact, it is nothing new that there are male doctors in obstetrics and gynecology, whether it is a natural birth or a caesarean section, male doctors will participate. Men and women are the same in front of the profession, and at critical moments, male doctors are calmer than female doctors.

In a hospital in my hometown, there is a very famous male doctor in obstetrics and gynecology, and he has a mastery - fetal position correction.

If a pregnant woman has an abnormal fetal position, even if there is fetal reversal, as long as he pushes and other actions, the fetal reversal and body position correction can be completed.

I'm not a medical student, and although I don't know how difficult this kind of fetal alignment is, I was very surprised and admired.

Every doctor who saves lives and helps the wounded deserves our admiration.

"Has the deceased's home address been found?" I fixed my mind and asked again.

"It's been found, and here it is." After Captain Jiang finished speaking, he stomped his feet and signaled that the deceased's home was at our feet.

The body was carried into a body bag, where it was later carried into a body truck and taken back to the Ningzhou Public Security Bureau for further autopsy.

Next, we followed Captain Jiang's footsteps and came to the door of room 601.

The technical team was unlocking, and after a while, the door lock was opened, and we walked into the house.

The walls of the doorway and the shoe cabinet were covered with splatters of blood.

We found no visible traces other than bloodstains. It seems that the murderer has no extra actions in this room, and he will leave after killing someone.

Unlike Xu Yufen's crime scene, the murderer did not clean up the bloodstains at the scene. Maybe the murderer felt that he didn't enter the room and there was no need to clean up, or maybe the bloodstain cleaning at the scene of Xu Yufen's crime was just the murderer's casual movements.

The technical team immediately entered the site to investigate the work, and Ren Qiushi also stood beside me, observing the situation in the room.

"It seems to be consistent with our autopsy, where the killer struck the deceased on the head with a blunt object, killing him." Ren Qiushi said lightly.

"Have you found any clothing of the deceased?" I asked.

Jiang Tingbai was leading a team to investigate the house, and after a while, he walked up to me and shook his head: "I didn't find any blood-stained clothes. ”

"Sixty-nine-year-old, you can't be bare-bottomed at home, right? Did he have no clothes on when he was killed? I frowned suddenly, put on the protective equipment used to investigate the scene, and walked into the scene of the crime.

The body was naked, and my first reaction was that the deceased was taking a bath when the murderer committed the murder.

I walked straight into the bathroom in my room, which was very clean and tidy, not even a single water stain.

The bathroom is not big, there is a toilet in front of it, a sink and shower head on the left, and a washing machine on the right.

"Is this old man so open?!" The more I thought about it, the more strange it became.

When Xu Yufen was killed, we found blood-stained clothing at the scene.

But at the scene of the crime this time, the deceased's clothes were missing.

And judging from the splattered blood stains at the door, the murderer did not enter the room at all after committing the murder at the door......
