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

Chapter 122 The murderer had planned the dinner in advance!

Can capsule-sized potassium cyanide powder cause death in a short period of time?

Su Ming's question.

In an instant, the eyes of everyone present brightened up, and they immediately thought of a certain possibility.

Shen Lin was stunned for a moment, and then used her professional knowledge to confirm seriously.

"Naturally."

"Take common drugs in our country as an example. The weight of the powder contained in the capsule is between 0.5 grams and 1 gram."

"Of course, this refers to the weight of the drug powder in the capsule, not the weight of the entire capsule."

"The lethal dose of potassium cyanide is roughly between 0.1 and 0.2 grams, which can poison adults to death in a short period of time."

"If the dose is increased to 0.5 grams, or even more than 1 gram, I think once the capsule shell dissolves, people will inevitably lose consciousness, have cramps in their hands and feet, and die from myocardial infarction in a very short period of time."

"That kind of large dose of potassium cyanide in a short period of time will cause a person to first suffer from cardiac arrest and cause black vision and coma. Naturally, it will be too late to call for help."

"at the same time."

"If the capsule shell surrounding the powder is made of different materials, the time required for it to melt in the stomach will also be different, which can control the time of the murder to a certain extent."

"And the most important thing is..."

"Even though cyanide can kill extremely quickly, because the capsule shell is made of gelatin, it only needs warm water to melt and disappear."

"So even if the victim loses his physical body, the gradually lowering temperature can completely melt the capsule shell, so that the capsule shell cannot be found in the stomach contents during the autopsy."

"Cyanide will be absorbed by the mucosa at the fundus of the stomach and dissolve into the blood very quickly."

"As long as the time when the victim's body is discovered is extended to one hour after death, the symptoms of death due to consumption and injection will be basically the same."

When Shen Lin revealed this professional forensic autopsy knowledge.

Even though his criminal investigation skills had deteriorated, Liu Yang, who was now more adept at officialdom, immediately understood Su Ming's intention in asking about the capsule earlier.

Bai Yu, who was wearing a suit, played with the pipe in his hand and analyzed thoughtfully.

"According to Brother Ming's idea."

"Then the method used in this movie theater poisoning and murder case should be..."

"The murderer did not use a syringe to inject cyanide poison into the victim. Instead, he used capsules to hide the poison."

"You only need to deal with the gelatin shell that wraps the powder, and then you can naturally control the approximate poisoning time of the victim."

"Then."

"The pinprick wound on the victim's buttocks is probably just a false clue to confuse the public, but it feels like we can roughly figure out the scope of the murderer."

"First of all, normal people will not take drugs handed to them by strangers, but now the victim has a high probability of taking the capsule drug and died, which means..."

"The murderer probably knew the victim, and the relationship between the two was very close, so he could exchange the drugs."

"Secondly, it is not difficult to create a needle wound on the victim's buttocks if the victim is a close friend. It can be done during a fight or by hiding the needle in the bed."

"Under this inference."

"Then the murderer of this case is most likely someone who knows the victim well."

"It stands to reason that once a case occurs, the people around the victim must eliminate suspicion as soon as possible, but the special nature of potassium cyanide should have made Xiangcheng Criminal Investigation ignore this at the time."

"because."

"Cyanide kills extremely quickly. In just a few minutes or even seconds, the victim can die of myocardial ischemia."

"In addition, the pinprick wounds on the deceased's buttocks found in the autopsy undoubtedly focused the attention of the police on the seats in the cinema or the people at the scene."

"And the real murderer only needs to have absolute alibi when the victim's capsule opened and died, and then the suspicion can be completely eliminated in the eyes of the police."

"This is a more commonly used case technique in Conan and other crime-solving works."

"But I have to admit that it is indeed very easy to evade police tracking, especially coupled with the fatal toxicity of cyanide."

"There is indeed a possibility of omission..."

heard here.

Liu Yang recalled carefully for a few seconds, then shook his head and frowned.

"wrong."

"I just thought about it. At the beginning, our Xiangcheng Criminal Investigation Team placed its main target near the theater to screen who might commit crimes."

"But for strict consideration, we actually checked whether the victim had taken drugs or sought medical treatment when sick."

"But there was also no result. At least for a few weeks, the victim had no consumption records of seeing a doctor in the hospital."

"There was no residual drug metabolism in the blood after the autopsy."

Regarding Liu Yang’s rebuttal and confusion.

Su Ming didn't think much and immediately told the story.

"Director Liu, there is a detail you forgot."

"I read the file specifically yesterday. The victim was a graduate of the software major, and his family's financial situation was not very good, so he applied to be a poor student."

"Even for my tuition, I applied for a national student loan. I was very frugal in my daily life and food. After I worked as a code farmer, my financial situation improved a little, and I was able to go to the movies and so on."

"But judging from the victim's usual frugality, is there a possibility..."

"Even if it's unfinished cold medicine, he will deliberately save it for the next time he catches a cold."

"If the physical discomfort is due to the same symptom, the victim does not need to buy any more medicines and can just take the remaining medicines."

this moment.

Liu Yang was stunned immediately. At that time, Xiangcheng Criminal Investigation Brigade did not think of this detail at all.

But Su Ming's inference was not over yet. He narrowed his eyes and continued his analysis seriously.

"Compared to cold medicine."

"I'm actually more inclined to believe that the murderer probably disguised potassium cyanide powder as a stomach medicine."

"Because of the victim's coding job, he was destined to work a lot of overtime. He had irregular meals due to his busy work. At the same time, in order to save money during college, he must have skipped breakfast as much as possible."

"According to a professional questionnaire report, among college students, the probability of stomach problems among college students with poor family conditions is much higher than that of students with better conditions."

"The time when stomach pain occurs is mostly in the evening after eating, or in the morning after not eating."

"The deceased was poisoned late at night. I think it is most likely that he took a capsule drug similar to Omelatzo in advance to prevent stomach pain."

"Office workers who suffer from stomachache all year round will basically have a variety of temporary stomach medicines to relieve pain. People like the victim who are used to frugality will naturally be reluctant to go to the hospital every time they have a stomachache. It is normal to buy medicine as a backup."

"But the problem is..."

Speaking of it.

Su Ming paused for two seconds, then tapped the whiteboard lightly and spoke slowly, squinting his eyes.

"Since the victim suffers from stomach pain all year round, he must have exercised some restraint and would not overeat and try to reduce the number of stomach pains as much as possible."

"Then on the day he was poisoned."

"Why did the victim take stomach medicine in advance? Did he guess that he might have stomach pain that night?"

"Or......"

"He already had a stomachache and was reluctant to give up the movie for which he had bought tickets, so he took medicine to survive?"

"So now I very much suspect that on the day he was poisoned, the victim probably had a special dinner or party that he couldn't refuse."

"And the murderer created this incident specifically around this dinner party that he had already announced..."

"Potassium cyanide poisoning case in private theater!"
