Netherworld Investigator Chapter 507: Restart the old case

lnmao.org, the fastest update to the latest chapter of Sin Hunter (Detective of the Underworld)!

In order to confirm this point, I checked carefully, and it turned out that there were two sets of handprints on the deceased, especially a pair of heavier handprints on the shoulders. From the direction of force, it seems that when a murderer was committing a rape, another helper held the deceased from above.

Rape and murder that are not for the purpose of revenge are often very private. Generally speaking, the murderer will not share the criminal process with others, but this case is abnormally done by two people together.

Is it true that someone is deliberately imitating the case of the year, but it is still not a conclusion, maybe it is just revenge!

At this time, Sun Bingxin walked in and said, "Big Brother Song Yang, I found out that the blood contains a small amount of chlorpromazine hydrochloride."

I was a little surprised: "Why is it so fast this time?"

Sun Bingxin smiled and said: "This tranquilizer was also tested on the last corpse, and the sample was still stored in the laboratory. I compared it with my hand. The result was as lucky as winning the lottery, and it was tested all at once."

As soon as she reminded me, I remembered that the same drug was found in the last corpse, so it is very likely that the two cases were done by the same person.

What I want to determine now is whether the killer used the medicine this time by injection or by taking. If it is the latter, then more medicine ingredients can be found in the stomach and intestines.

I ordered: "Check the stomach contents immediately!"

Sun Bingxin picked up the scalpel. Before going down, I rubbed the scar on the deceased’s abdomen with my finger, and asked Sun Bingxin if it was from a caesarean section. She said it should be.

I did a general check. From the melanin secretion around the scar, it was five or six years old, indicating that the deceased had a five or six-year-old child. I signaled that Sun Bingxin could have the knife.

We found some food residues in the stomach of the deceased. It was not very meaningful, but it proved the time of death. Sun Bingxin took some gastric juice for testing.

The body does not need to be examined again. I burned a few pieces of yellow paper for the deceased and asked the fat police officer: "How was the investigation of the last case?"

The fat police officer replied: "The deceased's name was Xiaofeng. He worked part-time as a prostitute and occasionally had **** with regular customers. We visited the restaurants around the scene and found a Sichuan restaurant that said he had met Xiaofeng. Feng, there was also a man who was travelling with him. He wore a mask and sunglasses. He did not know what he looked like. He was about 1.75 meters tall and of medium build. It was initially determined that this was the suspect. We are investigating the surrounding videos."

I faintly feel that this case is related to the case 20 years ago, and I am preparing to submit a cooperative investigation. Huang Xiaotao gave me a wink and said to the fat police officer: “I didn’t formally introduce myself before. My name is Huang and his surname is Song. We belong to the Nanjiang Special Case Team, an independent criminal agency under the Ministry of Public Security! The purpose of this visit was to investigate the Ryokawa serial murder case that year. The two cases that occurred now seem to be related to that case. If not, If you mind, I hope that both of us can work together, and the credit goes to you afterwards."

The fat police officer smiled embarrassedly: "If you don’t take credit for anything, I’ve already seen that you have a good background. If you can solve this case and still have peace in Liangchuan, I’ll be worthy of myself. The police badge! Don’t hesitate to tell me what help you need, I will give my full support."

Huang Xiaotao looked at me and said: "Song Yang, you can command!"

I nodded: "Comrade police officer, first gather all your subordinates and assign some tasks."

"Okay, I will call now."

The fat police officer went out first, and Sun Bingxin came in. She said that more chlorpromazine hydrochloride was tested in her stomach. It seems that the murderer had prepared a lot of this tranquilizer, which can be used as an investigation direction.

Huang Xiaotao wondered: "This small county has been quiet for 20 years. This imitation crime happened when we came. Is this case really caused by us?"

I said: "It should not be. When the first case happened, we had just arrived. I think the **** of swords knew something beforehand, so he reminded us at this juncture!"

Sun Bing said angrily: "He knows why he didn't stop it! The two girls died like this, it's a pity."

Huang Xiaotao sneered: "He is just a pervert who pretends to be the incarnation of justice, and he is not a hero, so why stop it."

What they said reminded me why the sword **** didn't stop it, could it be said that he thought the two dead were worthy of death!

I suddenly thought of something, and immediately asked: "Has the identity of the second deceased been found out?"

Huang Xiaotao said: "Ask the fat police officer later!"

It’s only 6:30 in the morning, and the police officers haven’t come yet. Huang Xiaotao suggested going out for breakfast first. I want to ask Sun Bingxin to compare the DNA of the two dead. Sun Bingxin asked: "You doubt her Are they related by blood?"

I said: "It's just a guess of mine. I have worked hard for you. I will invite you to dinner later."

Sun Bingxin smiled and said: "You are welcome!"

The pace of life in the small county is really slow. The police officers arrived at nine o’clock one after another. We held a case study meeting. The two sides exchanged information. I asked them to help find a few clues: the two deceased’s Detailed identities; possible surveillance videos and eyewitnesses at the time of the case; whether there are discarded murder weapons around the scene; the source of the chlorpromazine hydrochloride used by the murderer; and all the people involved in the serial homicide case 20 years ago.

After the meeting, Wang Yuanchao went to investigate the identity of the deceased. I plan to meet the injured police officer-Nie Yalong!

Just about to leave, the fat police officer came after him, holding an empty potion bottle in a bag, saying it was an exhibit found in the last murder case.

I took it in my hand in astonishment. The medicine bottle said ‘Tetanus Immune Globulin’. This is a common tetanus vaccine on the market. I asked the fat police where they found it? He said it was found in the handbag that the deceased had left in the room.

Huang Xiaotao said: "The bottle is empty. Is the potion injected into the body of the deceased?"

The first deceased, Xiaofeng, was pushed down from a height and fell to death. His whole body was **** and bloody. I can't guarantee that there was no needle eye, but I can be sure that she did not have tetanus. Because if it is pierced by rusty metal, the wound will be very conspicuous, and I will never miss it.

Sun Bingxin suggested: "Let's have a test. I have saved several blood samples of the last deceased."

So we came to the laboratory, the DNA sequencer was still working, and Sun Bingxin took out the marked blood sample from the refrigerator. The directional test is very fast. The result came out in less than fifteen minutes. Sun Bingxin said: "There is no tetanus vaccine in the blood of the deceased!"

Huang Xiaotao asked: "Are you sure?"

Sun Bingxin replied: "I tested three sets and the results were all negative, absolutely nothing."

I played with the small bottle in my hand. I really couldn't figure out the meaning of this thing in the bag of the dead. I pondered: "Is it the same as that gecko, is it some kind of message that the murderer wants to convey?"

Huang Xiaotao helped her forehead: "The two have nothing in common. Don't think about it. If every clue is meaningful, the case will be solved too well..."

I smiled: "You are right!"
