Crime Hunt Files: Bloody Angel

He Wei let out a long sigh, "It is still a poison that is explicitly prohibited from production, sale, and use by the state."

"I won't ask why Poisonous Rat Qiang appeared. What I want to know is why you said those words to me when you left. Did you already guess it?"

He Wei asked Cheng Nuo to sit down, and then explained: "Because the appearance of strux vomica in the cake is very inconsistent, even if it is ground into powder or washed with water as we initially deduced, these can change its appearance. Can’t stand the taste.”

"What about poisonous rat poison? It's not against the rules. It is originally a white powdery poison. In addition to the advantage of being tasteless, it is also very difficult to put it into the cake silently."

He Wei didn't say a word. Cheng Nuo's words and the surveillance video were like two flying threads intertwining in his mind.

Poison Rat is strong, white powder, odorless.

Suddenly, He Wei's mind flashed back to the conversation between him and Xiao Min at the crime scene.

"what is this?"

"Moisture-proof powdered sugar, there are many cakes like this now."

He Wei suddenly raised his head and stared at Cheng Nuo, "Moisture-proof sugar powder."

Cheng Nuo was instantly exposed. He opened his mouth in shock, stretched out his index finger and shook it in the air, "You mean the murderer didn't hide the poison in the cake at all, but sprinkled it directly on top of the cake! "

Let the victim watch the poison go into his mouth.

"It's so vicious." Cheng Nuo couldn't believe it. "If your guess is correct, the murderer's psychological quality and abnormality are not what ordinary people can achieve."

He Wei glanced at his watch, stood up on his knees, and said through gritted teeth: "The act of killing is not something that ordinary people can achieve."

"Then what's the next step? The suspects haven't been identified yet."

"It's okay." He Wei counted the time, "Maybe there will be new progress when Feichen comes back from the cake shop."

"Wait." Cheng Nuo stopped He Wei who was about to walk out. He raised another report in his hand, "There is another one, you haven't read it yet."

Howie narrowed his eyes. Cheng Nuo's expression was calm, but reporting the autopsy of a case separately was not something he would do unless something went wrong again.

At [-]:[-] in the morning, Feichen and Chen Zeyang took the surveillance video of the cake shop and split up as soon as they entered the door. On the one hand, he quickly selected the guests who met the requirements in the video, and on the other hand, he went to find He Wei.

He Wei couldn't wait any longer. He immediately stood up and walked to the door of Team [-]'s office. He reached out and patted the door and said, "Everyone, conference room, let's have a meeting."

Everyone quickly followed He Wei with their notebooks. When they opened the door, Cheng Nuo was already standing at the front of the conference table waiting for them.

Cheng Nuo thought about it while holding the document in his hand. After everyone was seated, he picked up the remote control and clicked on the projection behind him.

"The first is information about the deceased."

Four ID photos appeared on the big screen, two men and two women.

Cheng Nuo circled the laser pointer around the first photo in the upper left corner and introduced: "The first one is the deceased Bao Li, female, 33 years old, the owner of Ali Cantonese Claypot Rice Shop. Walking sideways, the second one, Zhao Zhengxing, male, 30 years old, is a chef in the store. The third person, Li Feng, female, 52 years old, is an assistant chef. The fourth person, Zhang Minghua, male, 54 years old, is a dishwasher and is the only one found behind. The body of the cook. The time of death was between [-] and [-]:[-] last night."

After sitting down, Shang Siwen, the only female detective in the third team, asked: "What's the cause of death?"

"Poison, don't you know?" Han Yang turned to look at her, his tone was like gossip.

Before Shang Siwen rolled his eyes, Cheng Nuo immediately answered: "Han Yang is right, poison, so let me ask you, what kind of poison is it?"

In an instant, everyone present looked at Han Yang.

Han Yang only knew that it was poison. He had never heard anyone mention the poison. How could he know? Forget it if I don’t know, but I was so lucky to be called out that I became nervous and subconsciously looked towards the first position on the opposite side, where I happened to meet He Wei’s expressionless face.

Cheng Nuo knew very well about He Wei's position in the bureau. Especially in the third team, it’s almost like a cat if not a mouse.

Stop it when you see it, tease it and run away.

"Okay, everyone, look at the screen and listen to me."

Cheng Nuo looked at the screen, and the photo of dishwasher Zhang Minghua in the lower right corner disappeared.

Cheng Nuo drew a circle on the remaining three photos, "Respiratory failure caused by poisoning, some of which showed punctate hemorrhages in the brain parenchyma and brainstem and necrosis of the contraction zone of ventricular myocardial fibers. The corpse mainly showed signs of asphyxia. Combined with the toxicant analysis results It is judged that he is poisonous and strong."

"Poisonous rat strong?!"

Not only Han Yang, but also all the uninformed people present took a deep breath after hearing this result.

"Didn't the production and sale of Dushuqiang be banned as early as the [-]s? Why does it still appear?"

Feichen also had the same question, "Is it related to the sleeping pills in the daily rental villa case?"

Han Yang exclaimed, "Is he another drug dealer?!"

He Wei said nothing. Compared to the source of the poison, there was another aspect of this case that was even more bizarre.

He looked at Cheng Nuo and signaled him to finish.

Seeing He Wei's attitude, the discussion in the conference room immediately disappeared, and everyone sat upright, waiting for Cheng Nuo to continue.

Cheng Nuo understood, he turned sideways and pointed at the screen and pressed again. The original photo of three people turned into two other people.

"The man on the left is Zhang Minghua, the dishwasher I just introduced. On the right is the only survivor of this poisoning case, Wang Xiaozhi, 28 years old, a waiter like the boss Bao Li. As for why I divided them into two The reason why the team came to introduce them is because the poison in the two of them is different from the previous three people."

……

As soon as these words came out, everyone in the third team pressed the pause button. For a moment, no one could react to what Cheng Nuo said.

Originally, Cheng Nuo wanted to give them some time to think. He Wei raised his chin and reminded him: "Continue."

Cheng Nuo nodded, "Then let me directly conclude that what Wang Xiaozhi and Zhang Minghua were suffering from was not poisonous rat poison, but Nux vomica. It is a traditional Chinese medicine that is also highly toxic."

Speaking, Cheng Nuo clicked the screen twice, "The strychnine in Nux vomica, also called strychnine, prevents the destruction of acetylcholine by cholinesterase. Acetylcholine is retained in the tissues, causing poisoning of the entire central nervous system. Excitation of the nervous system; causing over-limit inhibition in the cerebral cortex, causing a significant increase in the reflex excitement of the spinal cord and special forced spasms, eventually leading to tonic contraction of breathing and death by suffocation."

Chen Zeyang leaned forward and asked, "Are the two poisons on the same cake?"

Recalling last night, the three of them stared at the surveillance video. From the time the cake appeared at about [-] p.m. to nearly [-] p.m., the cake was eaten by the five victims in the store.

In the middle they ate nothing but cake.

The weirdest thing is that the surveillance video ends after everyone has eaten the cake. I still remember that they didn't find any tableware or anything related to the cake at the crime scene. At that time, Howie concluded that the murderer returned to the scene and recovered all the evidence of the crime.

The surveillance was stopped by the murderer.

Stopped before everyone became poisonous.
