After 100,000 simulated crimes, I became an ace detective.

Although the specific membership structure of the entire drug trafficking organization is not yet known.

But the fact that Qiangwei joined the organization and knew how to make human skin masks was enough to rank her very high in the order of arrest.

and so.

Instead of continuing to poach other members of the organization, it is better to target Qiangwei first.

Just to prevent Qiangwei from being executed in advance, it is necessary to create enough commotion in Gusu City.

The spying leader of the drug trafficking organization was completely attracted to Gusu City, leaving him no time to pay attention and arrange personnel to Liangxi City.

......

this moment.

Su Ming pointed to the poison code on the whiteboard, sorted out the information and said slowly.

"This huge drug trafficking organization called Kill arranges the members who maintain and develop the drug chain in Suzhou City to be codenamed Poison."

"Xi Qian."

"In order to pass the assessment of that organization, or submit a petition, Poison led a case called [Private Cinema Potassium Cyanide Poisoning Case]."

"About this case..."

Speaking of it.

Su Ming looked at Liu Yang beside him and stretched out his hand to indicate.

"Bureau Liu."

"As the head of the Xiangcheng Criminal Investigation Brigade, you should have been exposed to this poisoning case at that time, right?"

"As drug trafficking organizations have been uncovered in the past few days, many unsolved cases have been brought up again."

"I think... you must have read the file on this poisoning and murder case several times recently, so could you please give me a brief summary of the case?"

Compared to others present.

As the head of the Xiangcheng Criminal Investigation Brigade, Liu Yang was naturally more aware of this case. He then nodded gently and sorted out his thoughts.

"The specific time of the potassium cyanide poisoning case in a private theater was July 2018, 7, which is almost five years ago."

"Although a long time has passed, I still remember the general situation quite clearly, because I was the one leading the team to detect clues and find the murderer."

"First of all, the time for calling the police was around [-] a.m., which also refers to the first time the victim's body was discovered. We drove there immediately after receiving the police report."

"By the time we arrived at the scene, the victim had lost the need for resuscitation. His pupils were cloudy and he had severe hypothermia. However, his complexion was red, and his hands and feet were convulsing. At that time, I suspected that the victim was cyanide poisoning. People die.”

"Because if it were replaced by other deadly chemical poisons, the victim should have the opportunity to shout and seek help and be sent to the hospital, instead of losing the need for rescue as soon as he is discovered."

"By the way, about these poisonous drugs."

"Forensic Doctor Shen should know better than me. Potassium cyanide should be widely used, right?"

heard here.

Shen Lin, who has extensive experience in autopsy, adjusted her gold-rimmed half-rimmed glasses and took over the conversation in a serious and affirmative tone.

"Potassium cyanide is indeed a commonly used poison and euthanasia drug."

"Compared with thallium or ricin, it has a faster onset of action and more severe toxicity. It only takes a few milligrams to easily kill adults. The key is that it has a quick onset of action and is much less painful. "

"Whether it is inhalation, ingestion, contact with skin and mucous membranes, or injection, sodium cyanide poisoning can occur, and injection poisoning has the fastest effect."

"Depending on the dose, it can take as little as ten seconds for the victim to lose consciousness and die of sudden cardiac arrest."

"And it is actually very simple to verify whether there is cyanide poisoning, and it is a basic requirement for forensic autopsy."

"Those who die from cyanide poisoning will have a cherry-red complexion, and their skin and mucous membranes will also turn bright red."

"As for the blood."

"It will not be dark red, but will appear bright red. At the same time, the time for condensation to produce corpse spots will be much shorter than normal."

"If the victim did not make any cry for help at that time, it means that he was probably injected with potassium cyanide and died."

"Then there must be pinholes. I think the forensic doctor in Suzhou City at that time should be able to easily detect this, and it will be described in the file."

Liu Yang nodded in agreement, then frowned in confusion.

"But therein lies the problem."

"According to our inference at the time, injection was undoubtedly the most likely way to cause the victim to die so quickly without even a cry being heard."

"Also after the autopsy."

"At that time, our forensic doctor in Gusu City also found a pinhole wound on the deceased's buttocks."

"The wound on the buttocks naturally raises serious suspicion that there is something wrong with the theater seats. Someone hid a syringe or something else under the seat."

"As a result, the victim accidentally sat on the syringe when he was sitting down. Since potassium cyanide takes effect quickly, there is no time for reaction."

"But we carefully searched the chair where the victim was sitting several times and found no syringe."

"Without a syringe, it's outrageous why the victim had a pinprick wound on his buttocks and how quickly the medication would take effect."

"And there is another very important point that makes this case difficult."

"Private cinemas are different from regular cinemas. There are no cameras installed at all, so it is impossible to check the specific situation of the victim at the time of the crime."

"That's why cases are so difficult to solve."

"The murder weapon could not be found, there was no surveillance, and the suspicious person could not be found, which suddenly brought the case to a deadlock and made it difficult to progress."

Listen to Liu Yang's description.

Lin Tian habitually sniffed his left index finger, which was full of tobacco smell, and said a little puzzled.

"Bureau Liu."

"I understand that there is no surveillance in the private theater, but why can't the suspicious person be found?"

"According to what you just said, there should have been more than one victim in the same small movie theater at that time. Didn't the others have any motive for the murder?"

Liu Yang sighed helplessly, shook his head and answered seriously.

"Although it is a small cinema."

"But in fact, that screening room can accommodate about 20-30 people, and it is specially used to screen films that are banned or removed from the shelves in China."

"There were a total of twelve people watching the movie. The victim bought a seat in the last row, and the rest of the people were in front of him."

"So when the movie ended and all the lights came on, someone noticed something strange about the victim."

"Based on our careful interrogation and review, we were able to roughly determine that the remaining eleven people had nothing to do with the victim. They just met by chance."

"It's very difficult. There are very few clues in this case. I feel that the murderer has never had contact with the victim. It is really difficult to solve the case."

The voice fell.

Everyone present was lost in thought.

Su Ming squinted his eyes and thought for a few seconds, then looked at Shen Lin not far away and asked with meaning.

"Forensic Doctor Shen Lin."

"I would like to ask, if potassium cyanide is taken orally instead of injected, what is the approximate dose required to make an adult die in a very short time?"

“Is a capsule the size of a cold medicine enough?”
