After simulating crimes 100,000 times, I became an ace detective

Although the specific structure of the entire drug trafficking organization is still unknown. (っ◔◡◔)っ

But the time when Qiangwei joined the organization and the fact that she knew how to make human skin masks are enough to make her arrest order extremely high.

So.

Instead of continuing to dig out other members of the organization, it is better to go straight to Huanglong and target Qiangwei.

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

The leader of the drug trafficking organization who is secretly spying will be completely attracted to Gusu City, so that he has no time to pay attention and arrange personnel to Liangxi City.

......

At this moment.

Su Ming pointed to the poison code on the whiteboard, sorted out the intelligence and thought slowly.

"This huge drug trafficking organization named Kill arranged members in Gusu City to maintain and develop the drug chain code-named Poison."

"Four years ago."

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

"About this case..."

Speaking of this.

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

"Director Liu."

"As the head of the Xiangcheng Criminal Investigation Team, you should have been in contact with this poisoning case at that time, right?"

"With the drug trafficking organization being dug out in the past few days, many unsolved cases have been brought up again."

"I think...you must have read the files of this poisoning case several times recently, so can you please tell me roughly what happened in the case?"

Compared to other people present.

As the head of the Xiangcheng Criminal Investigation Team, Liu Yang naturally knew more about this case, and then nodded gently, sorted out his thoughts and said.

"The potassium cyanide poisoning case in the private cinema happened on July 25, 2018, which is almost four years ago."

"Although it has been a long time, I still remember the general situation very clearly, because I was the one who led the team to explore clues and find the murderer."

"First of all, the alarm was called at about 1 a.m., which was also the first time the victim's body was found. We drove there immediately after receiving the alarm."

"When we arrived at the scene, the victim had lost the need for rescue. His pupils were cloudy and he was severely hypothermic, but his face was cherry red, and his hands and feet were still cramped. At that time, I suspected that the victim died of cyanide poisoning."

"Because if it was replaced with other deadly chemical poisons, the victim should have the opportunity to shout and seek help and be sent to the doctor, rather than losing the need for rescue as soon as he was found."

"By the way, about these poison drugs."

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

Hearing this.

Shen Lin, who has rich experience in autopsy, adjusted his gold-rimmed half-frame glasses and took over the conversation seriously and affirmatively.

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

"Compared with thallium or ricin, it takes effect more quickly and is more toxic. Only a few milligrams are needed to easily poison an adult. The key is that due to its rapid onset, the pain is much lower."

"Whether it is inhaled, ingested, contacted with the skin or injected, it will cause sodium cyanide poisoning, and injection poisoning is the fastest."

"Depending on the dosage, it only takes ten seconds at the fastest to make the victim lose consciousness and die of cardiac arrest."

"And to verify whether it is cyanide poisoning, it is actually very simple, and it is also the basic requirement of forensic autopsy."

"The complexion of a person who died of cyanide poisoning will be cherry red, and the skin and mucous membranes will also be bright red."

"As for the blood."

"It will not be dark red, but bright red, and the time it takes to coagulate and produce corpse spots will be much shorter than normal."

"If the victim did not make any sound for help at the time, it means that it is very likely that he was 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 check this, and there will be a description in the file."

Liu Yang nodded in agreement, then frowned in confusion.

"But here's the problem."

"According to our inference at the time, the victim died so quickly without even a cry, so injection is undoubtedly the most likely cause."

"At the same time, after the autopsy."

"At the time, our Suzhou City forensic doctor also found a pinhole wound on the buttocks of the deceased."

"The wound on the buttocks naturally seriously suspected that there was a problem with the theater seat. Someone hid a syringe or something else under the seat."

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

"But we carefully searched the chair where the victim sat several times and did not find the existence of the syringe."

"Without a syringe, why did the victim have a pinhole wound on his buttocks, and why the drug took effect so quickly? This is really outrageous."

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

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

"This is why the case is difficult to solve."

"There is no murder weapon, no surveillance, and no suspicious person. The case has come to a standstill and is difficult to progress."

Listening to Liu Yang's description.

Lin Tian habitually sniffed the tobacco-smelling index finger of his left hand, a little puzzled.

"Director Liu."

"I understand that private cinemas don't have surveillance, but why can't they find suspicious people?"

"According to what you just said, there should be more than one victim in the same small theater. Don't other people have motives for the crime?"

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

"Although it is a small theater."

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

"There were a total of 12 people watching that movie. The victim bought a seat in the last row, and the others were in front of him."

"So it was not until the end of the movie and the lights in the theater were turned on that someone noticed the abnormality of the victim."

"Based on our careful interrogation and review, we were able to roughly determine at that time that the remaining 11 people had no intersection with the victim, and simply happened to meet him in this scene."

"It's difficult. There are very few clues in this case. I feel that the murderer has never contacted the victim. The difficulty of solving the case is too great."

The voice fell.

Everyone present fell into thought.

After squinting his eyes and thinking for a few seconds, Su Ming looked at Shen Lin not far away and asked meaningfully.

"Forensic doctor Shen Lin."

"I want to ask, if potassium cyanide is taken orally instead of injected, what dose is needed to kill an adult in a very short time?"

"Will a dose the size of a cold medicine capsule be enough?"
