In the car, Li Meng and I exchanged clues that we had investigated.

"I found out some of the past in Xinling County." I spoke slowly.

"What's the past in Xinling County? Haven't we already checked the county records? Li Meng looked at me with some puzzlement and asked softly.

I smiled faintly and said in a cold voice: "There are some dirty things that will not be written in the county chronicle." ”

At this moment, Li Meng was even more puzzled, and muttered: "Dirty things? ”

"In the sixties of the last century, Xinling County opened a heavy factory, which led to serious mercury pollution in Xinling County, and the residents had serious mercury poisoning, and the rate of child deformities was very high. But I think this kind of thing is a bit ridiculous, maybe this information is not accurate, maybe the real situation is more serious than that. I spoke slowly and said lightly.

"It's ridiculous......"

When Li Meng heard the news, her eyes were full of shock, she couldn't believe that this kind of thing could happen, even if these words came out of my mouth, she still couldn't believe it.

I took a deep breath and waved my hand a little helplessly: "For these things, no matter how dirty, as long as it has nothing to do with the case we are currently investigating, we don't want to waste time." After all, this kind of thing, there is no evidence, everything is passed down by word of mouth for forty years, and the credibility is not high. ”

"Indeed, from the current point of view, this matter has little to do with this case." Li Meng muttered.

After a while, Li Meng suddenly felt that something was wrong, and said something that he had always been very puzzled about: "If the killing of Xu Yufen and Liang Dongsong is related to the fire forty years ago, then it is easy to understand that the murderer sewed the two dead into a fist-like posture of burning the fire." But it is precisely because of this that the murderer will tell us through these two murders? Could it be that there is something else hidden in the fire 40 years ago? ”

I nodded, followed her train of thought, and continued: "It's possible, maybe that kind of hidden secret, only we, as police officers, have the ability to continue to investigate." Moreover, didn't you find that the murderer's behavior of killing people and sewing corpses and throwing corpses is abnormal? ”

Li Meng sat up straight suddenly, looked at me with some excitement, and said seriously: "That's right, I've been thinking about this question for a long time, if the murderer just wanted to sew the corpse into a fist-like posture after the fire, then why did he throw the corpse into the water?" Xu Yufen's body was dumped in her bathtub, and Liang Dongsong was abandoned in the tap water tank on the roof of the building. ”

I smiled slightly and said lightly: "Do you know why Liang Dongsong was abandoned in the tap water tank on the rooftop?" ”

"Why?" Li Meng asked me immediately.

"Because Liang Dongsong's home only has a shower, no bathtub." I said coldly.

"Therefore, sewing into a fire-burning fist-like posture and throwing corpses into water are very critical conditions, and they are indispensable." Li Meng nodded and muttered, "If the fist-like posture is a sign of fire, then it is unreasonable to put it in the water." ”

"Indeed, perhaps we have gone into a misunderstanding from the very beginning." I said in a deep voice.

Li Meng fell into deep thought, and she sorted out all the clues of this serial murder case: "Skull contusion and wound, fist-like stitching, immersion in water, fire in Xinling County Hospital, retired staff of the Obstetrics and Gynecology Department of Sanhe County People's Hospital......"

Li Meng muttered for a while, suddenly raised his voice, and said sharply: "Obstetrics and gynecology!" Pregnant woman! Fetus! ”

"Yes, it does." I nodded, agreeing with her.

It's just that all of this was just when the pigeon was going to have a caesarean section for a pregnant woman during the day, and the nurse's sentence "the amniotic water broke" made me suddenly think everything through.

"Therefore, the murderer has to use his own way to tell the police something about the fetus." Li Meng continued.

"If you think about it this way, it seems to be related to the Xinling County Hospital. But what does the murderer have to do with these events? I spoke slowly.

Now it seems that this issue is very critical, the murderer has now killed two people in a row, if this matter has nothing to do with him, he will definitely not pay the price of killing.

"No matter how things develop, the nature of the case will always remain the same, which is a very typical vendetta. While taking revenge, the murderer left clues for the police to investigate the matter. Li Meng analyzed in a deep voice.

"But what can we police do about this? We are not gods, and there are many things that cannot be thoroughly investigated, especially such things that happened more than 40 years ago. I let out a long sigh of frustration and pulled over to the side of the road.

From the Sanhe County People's Hospital, we returned to the scene of Liang Dongsong's crime.

The on-site investigation has been completed, and the technical team is sorting out the physical evidence and preparing to take it away.

"Lao Qin, the scene has been investigated, and no clues have been found, but on the way from Liang Dongsong's door to the rooftop, we found dripping bloodstains, which should be the dripping blood stains in the process of the murderer's transfer of the body and throwing the body." Jiang Tingbai said to me.

I nodded and said lightly, "Close." ”

I decided to set up the location of the case analysis of Liang Dongsong's murder at the Sanhe County Public Security Bureau, which is close to the Sanhe County Hospital, and it is easier to conduct a follow-up investigation into Liang Dongsong's social relations.

The forensic department took Liang Dongsong's body back to the Ningzhou Public Security Bureau for an autopsy, because this was a serial homicide case, and there were many details that needed to be compared with Xu Yufen's body.

Everything else, including trace examination, is being investigated at the Sanhe County People's Hospital.

Yesterday, we found Xu Yufen's body.

Today, we found the body of Liang Dongsong.

Although the time of Liang Dongsong's death cannot be determined, we know that the murderer will definitely commit the crime again until he is arrested.

Lin Zifan went to investigate Liang Dongsong's social relations, Xue Hang went to visit and investigate the surveillance video to find clues to the murderer, and Jiang Tingbai took the technical team to work in the trace inspection department.

Li Meng and I sorted out and analyzed the information of the obstetrics and gynecology staff I had just brought back from Yang Fan, the director of Sanhe County People's Hospital, to find people who matched Xu Yufen and Liang Dongsong, and to predict the murderer's next murder plan.

"Is there anything I can help me with?" Jiang Ke, the head of the criminal police squadron of the Sanhe County Public Security Bureau, walked up to me and asked softly.

"Can you find out the content of Xinling County?" I raised my head, looked at Captain Jiang, pondered for a moment, and slowly spoke.

"Xinling County? What are you looking for? Captain Jiang asked puzzled.

"I need to check the content of the obstetrics and gynecology department of Xinling County Hospital." I said seriously.

Captain Jiang looked at me, thought for a while, and muttered: "When the three counties were merged, all the information of Xinling County, Yimen County, and Ningmen County was indeed handed over to us in a unified manner, and later we made a backup for the county government, which should be able to be checked." ”

"Great! Where is the information? Li Meng asked with some excitement.

Captain Jiang looked at us, blinked, and said lightly: "In the archives." ”
