Serious Crime Unit 1

Chapter 980 Falling from the Building (4)
He didn't think about it anymore: "Please lock this bedroom and don't let anyone in. We need to investigate your husband's death. Therefore, I ask you to let us transport Zhang Huai's body to the Municipal Bureau Forensic Center for investigation. Autopsy.”

"Autopsy? Isn't that disembowelment?" She felt very strange.

"Yes, only an autopsy can tell how Zhang Huaiyou died."

"Isn't that cruel?"

"People have no feelings after death. It's not cruel, it's just a psychological problem. After we finish the autopsy, we will sew the body up so that it looks the same." Luo Jin tried his best to keep his tone gentle.

"Why an autopsy?"

"We suspect that Zhang Huaiyou fell to his death accidentally."

"Ah? Was he murdered? How is that possible?"

"We can't be sure at the moment. We won't know until the autopsy results come out."

Zhang Yu thought for a while and said, "Okay, I agree to the autopsy."

Luo Jin took the estazolam he brought back from Zhang Yu's house to a gas chromatograph for testing, and found that it was not estazolam, but a powerful form of triazolam. This surprised Luo Jin. He went online to check triazolam. After reading Triazolam's instructions, it was found that each tablet of triazolam is only 0.25 mg. Patients generally only need to take 0.5 mg, that is, two tablets, to fall asleep.

The specification of estazolam is 1 mg per tablet, which is 75% larger than triazolam. Of course, it is also 75% heavier. If Zhang Huai needs to take two tablets of estazolam before going to bed, then it is equivalent to taking two tablets of estazolam. I took 8 tablets of triazolam, which was much more than the ration.

As long as triazolam is taken in excessive doses, the human body will have toxic and side effects, mainly manifested as depression of the central nervous system, symptoms such as trance, dizziness, unsteadiness, confusion, memory loss, thirst and other symptoms.Zhang Huaiyou should have overdosed on triazolam, which made him dizzy and unsteady and he fell to death. His death was not an accident, but a murder!

However, without an autopsy, it cannot be confirmed that Zhang Huai took an overdose of triazolam, so an autopsy must be performed on Zhang Huai.Luo Jin came to Jiang Yiming's office and explained the situation to him.

"You're saying that someone secretly replaced the estazolam Zhang Huai had taken with triazolam, causing him to become dizzy due to an overdose and fall to his death from the sixth floor?"

"Yes, according to my current guess, that's the case."

"The specifications of each medicine are different, right?"

"Yes, each tablet of estazolam is 1 milligram, and there are also two milligrams, but the estazolam that Zhang Huai took is 1 milligram. Most triazolam is 0.25 milligrams."

"In other words, triazolam is three-quarters smaller than estazolam? With such a big difference in size, didn't Zhang Huai notice it when he took it?" Jiang Yiming didn't quite understand.

"The size of the triazolam I retrieved from the scene was also 1 mg. In other words, the murderer ground a lot of triazolam into powder, added a kneading agent, and poured it into a mold the same size as estazolam. , after it is formed, it is dried, so it has exactly the same specifications as estazolam. Although there are extremely small differences, ordinary people will never be able to tell."

"Is this easy to do?"

"It's not difficult. Most pharmaceutical workers can do this. Of course, if you have the guidance of a technician, you can learn it quickly, and you can also learn it online."

"This murderer is very thoughtful. Did you find any strange fingerprints on the medicine bottle?"

"I gave the medicine bottle to Angkor for inspection. I am not as professional as Angkor in checking fingerprints."

"We assume that the estazolam in Zhang Huai's possession was exchanged by the murderer for triazolam. Then, the murderer should be a relative or friend of Zhang Huai's, right? Otherwise, how could the murderer enter his home?"

"The house Zhang Huai lives in is a dilapidated building. It was the former Xiaokeng Primary School and was converted from two classrooms. He and his wife live on the first floor. There are no anti-theft nets installed on the windows. As long as Zhang Huai has the glass in the bedroom, The window was not closed and anyone could climb in, so it may not be Zhang Huai’s relatives or friends who did it.”

"Is the scene cordoned off?"

"Yesterday I ordered Zhang Yu to seal off the scene and not let anyone in."

"Well done! You first go to the autopsy to see if there is a large amount of triazolam in Zhang Huai's body, and then we will open a case for investigation."

Luo Jin nodded, walked out of Jiang Yiming's office, and returned to the forensic center.He and his assistant Dong Dawei began to dissect the corpse carried by Zhang.Luo Jin first cut open the chest of the corpse, extracted some of the blood, and then took it for testing, leaving Dong Dawei to do the rest.

The test results were not what Luo Jin expected. Zhang Huaiyou's body contained a large amount of triazolam.He told Jiang Yiming the result, and Jiang Yiming thought it was a clever murder case, so he started investigating.

Jiang Yiming called each team member to a small conference room for a meeting. After explaining the situation to everyone, he asked Wu Jiang: "Old Wu, what are the results of the fingerprints on the medicine bottle?" "There are only two types of fingerprints on the medicine bottle. One is a female's fingerprint, and the other is a male's fingerprint. I compared the male's fingerprint with Zhang Huai's fingerprint, and the result belongs to Zhang Huai's, while the female fingerprint should be Zhang Yu's."

"Are there no other fingerprints?"

"No. If the murderer is not Zhang Yu, then the murderer must have worn gloves to commit the crime."

"Through the autopsy, we have confirmed that this was a murder. Next we must investigate the case. Do you have any good suggestions?"

"I think we should start with Zhang Yu. First of all, there are her fingerprints on the medicine bottle. Secondly, she and Zhang Huai sleep in separate beds. This shows from the side that she and Zhang Huai are not on good terms, and she is somewhat pretty. , so maybe Hongxing is cheating on her." Luo Jin said.

"Well, this is an entry point... However, I think we should investigate Zhang Huai's bedroom. Let's assume that the murderer sneaked into the bedroom through the window and exchanged estazolam for triazolam. Then, his shoe prints It should be left on the floor in the bedroom.”

"If the killer entered the bedroom wearing shoe covers, we wouldn't be able to detect him."

"Zhou Ting, you and Luo went into Zhang Yu's house. Did you find any monitors nearby?"

"I made a preliminary observation and found no monitors nearby."

"Well, as usual, Yingying and Xiaorou will check the distribution of nearby monitors and find suspicious people. Lao Wu and Xiaoke will go to investigate Zhang Huai's bedroom, doors, windows, and exterior walls. Me and Zhou Ting went to ask Zhang Yu and then further investigate her social connections." Jiang Yiming divided the tasks.

Everyone drove two cars to Zhang Yu's house. Zhang Yu was very confused when she saw so many policemen, but she cooperated with the work. She opened the door of Zhang Huai's bedroom and asked Wu Jiang and Xiao Ke to investigate, and then sat opposite Jiang Yiming. , waiting for his inquiry.

"Ms. Zhang, we have now confirmed that Zhang Huaiyou was murdered, so..."

"Huh? Murder? My husband is an honest man who never offends anyone. He is kind and tolerant to others. He has a heart of a bodhisattva. How could someone murder him?" Her eyes were as big as a bull's eye, and she looked incredulous. In an instant, Surprise turned to anger.

"Someone replaced the estazolam in Zhang Huai's medicine bottle with triazolam. Triazolam is a powerful sleeping pill. Overdose of it can cause toxic side effects. The most common ones are dizziness and unsteady standing. Zhang Huai Some people fell down from the sixth floor and died due to dizziness. Have you ever touched that bottle of sleeping pills recently?"

"I can't remember that."

"Think about it carefully. This is very important to us, and it is also very important to you." Jiang Yiming looked at her. This was a habit he had developed when questioning suspects. He wanted to observe whether the other party was lying from their micro-expressions. This kind of The method is very effective.

She lowered her head and began to think. After a few seconds, she suddenly raised her head and said, "I remembered that I touched my husband's medicine bottle more than ten days ago because my husband had to go to work and had no time to go to the hospital to buy medicine. , almost every time I go to the hospital to help him get sleeping pills. The doctor stipulates that he is only allowed to take 30 tablets of estazolam at a time, which is only enough for him to take for half a month, so every half month, I have to go The hospital prescribed sleeping pills for him. After I got the sleeping pills back, I would put the bulk sleeping pills into the pill bottle, so I must have come into contact with the pill bottle."

"Has anyone else entered Zhang Huai's bedroom?"

"Except for me, few people go in. Guests usually sit in my living room and play, and don't go to his bedroom... You said that my husband took an overdose of sleeping pills, which made him dizzy and fell from the sixth floor? "

"Yes, the autopsy results are like this. There is no way to fake it."

"No wonder my husband couldn't get out of bed that day."

"Oh, did you wake him up?"

"Yes, because Hu Ji's house was to be completed that day. After I woke up my husband, he went to work after breakfast. I saw that he seemed to be in a bad mood, so I asked him to take a day off. He firmly disagreed. He said that if he was absent from work, the house would not be completed, so he had to go out to work. If I had known something would happen to him, I would not let him go out to work even if I were to kill him. Alas, it is all my fault for not knowing how to feel sorry for him." She said sadly.

"We judge that the murderer probably changed his sleeping pills on June 6. Were you at home that day?"

"That day was Monday. I had to go to work during the day, so I was definitely not at home. My husband also went to work."

"Did you close the doors and windows when you went out?" Jiang Yiming turned his head and glanced at the door. The door was equipped with a simple spring lock. The door could be opened with a card, which was a headache.

"It should be closed. We are the only family living in the whole school, so I always close the door when I go out."

"Did you go out that night?"

"Oh, we went out to play at Ouyang Di's house. My husband took me there on a motorcycle. Ouyang Di's wife came from Anhui to visit him. He invited us to have dinner at the Sanjiang Hotel. After eating, we went to sing again. I didn’t go home until 11 o’clock.”
