Solve the case: Justice makes you stronger

"Rat poison?"

"Is there anything wrong with rat poison?"

Hearing Xu Luo's words, Liang Tian thought about it seriously, but he still couldn't think of what was wrong here.

However, Qin Zhi, who was a forensic doctor, thought about something and seemed to think of something.

Xu Luo glanced ahead and found that the red light was still very long, and turned back to explain to the two women: "There are many types of rat poison, and the legal rat poison circulating on the market now is not so toxic, most of them are anticoagulants of the dicoumarin class, and the way to kill rats is to inhibit the metabolism of vitamin K in their bodies." "，

"Many kinds of coagulation factors are dependent on vitamin K production, so the metabolism of this vitamin is inhibited, and the coagulation function of mice or organisms that eat the drug will be impaired, and even a small wound will be easy to bleed, and excessive bleeding will hang."

The ingredient monitored in the bodies of the four victims is tetramethylenedisulfoxidetetramine, which is the main ingredient of the "850" drug of rats called "strong poisonous rats"! "

"This drug is a neurotoxin that can cause fatal spasms, and it is very powerful, because this drug will remain in the body of animals after poisoning, and some organisms will cause subsequent poisoning after eating the bodies of these animals, so it has been banned from production, that is, it is not circulated on the market."

"It can be seen from here that the poisoning of Zhu Zhongjun's family of four is definitely not an accident."

"After all, it's hard to buy this banned rat poison now!"

Liang Tian and Qin Zhi immediately nodded in understanding.

Indeed, there are so many rat poisons on the market, and as a result, Zhu Zhongjun's family of three just ate this rat poison that has been banned because of this very strong medicine, which is too much of a coincidence.

At this point, the possibility of accidental ingestion can be ruled out, and it is more likely that someone poisoned it.

"But what does this have to do with Zhu Zhongjun's suspicion?" Liang Tian continued to ask.

"There's a lot of suspicion here." It was Qin Zhi who answered Liang Tian.

After hearing Xu Luo's previous explanation, she had already figured everything out.

"Strong poisonous rat strong, also known as rat dead, nicknamed 424, the legendary rat three steps down, rat smells dead, chemical tetramethylene disulfone tetraammonia."

"Under normal conditions, it is a light powder, which can be dissolved in water, with a solubility of about .25mg/ml, decomposed in continuous boiling and aqueous solution, and is easy to decompose when heated, and will release oxide smoke of nitrogen and sulfur, which can also be absorbed through the digestive tract and respiratory tract."

"The lowest lethal dose of this poison for mammalian oral administration is one gram, which has an excitatory effect on the central nervous system, especially the brain stem, which can cause convulsions."

"Clinically, animals are excited to beat and even scream and spasm after poisoning."

"A little in the eyes will stiffen the limbs."

"It's similar to cyanide in trace amounts, and after taking this rat poison, the symptoms of mild poisoning are headache, dizziness, fatigue, nausea, etc.!"

"Severe poisoning is sudden fainting, convulsions all over the body, foaming at the mouth, urinary incontinence, shock and the like."

"The investigation record given to us by the General Bureau of Mirror Investigation of Hangyu City is attached to the autopsy report, I read it, and found that the poison content in the residual food at the scene was not low, and the three deceased swallowed a lot of it, reaching the level of death in half an hour!"

"From here, it's often strange that Zhu Zhongjun is still alive!"

Very, very strange?

was popularized by Qin Zhi for a while, Liang Tian was not annoyed, but listened very carefully, pondered, and recalled the information written on the investigation record.

Soon, she figured it all out.

This long list of rat poison is very poisonous, and it does not need to be very large to kill people, the more the amount, the greater the lethality, and the faster the attack!

The meals used by the four members of the Zhu family that day were all poisonous, and the amount was very sufficient, which could definitely cause death, according to Qin Zhi's meaning, the three of Zhu Zhenshan should have died half an hour after eating lunch.

This amount is very large, and it is estimated that the three of Zhu Zhenshan began to show signs of poisoning not long after eating.

According to the records on the investigation record, as well as the autopsy report of the forensic doctor of the General Administration of Hangyu City Mirror Investigation, it can be determined that the time of death of the three people in Zhu Zhenshan was eleven o'clock, and if you extrapolate it, the time when they had lunch should be half past ten.

Then the period from half past ten to eleven o'clock is the time period when the three people of Zhu Zhenshan have symptoms of poisoning.

The bodies of Zhu Zhenshan's three people, as well as Zhu Zhongjun, who was also poisoned, were found at 1:43, and the ambulance arrived at 1 or 2 o'clock, and at that time, Zhu Jun was sent to the ambulance, began to receive treatment, and finally survived.

According to the abbreviation of the investigation record, the poison content in Zhu Zhongjun's body was half of that of the other three, and this amount would take about an hour to cause death, so he didn't die until 12 o'clock, and was finally rescued.

There's a huge problem here.

According to the detailed extrapolation on the investigation records, the time of Zhu Zhongjun's poisoning should be around 1 o'clock.

And at this time, even if the three of Zhu Zhenshan are not dead, they are not far from death, that is to say, Zhu Zhongjun is still poisoned even though he knows that Zhu Zhenshan and the three people are poisoned, and the amount of poison in the body is much less, which greatly prolongs the survival time0...,

As soon as this is analyzed, the contradictions come out.

Why didn't Zhu Zhongjun call the police when he knew that Zhu Zhenshan and the three people were poisoned or even dying, and even the same poisoning?

When was Zhu Zhongjun at home, and what was he doing when Zhu Zhenshan was poisoned?

Why didn't Zhu Zhongjun call the ambulance, was he committing suicide?

These three questions are the three biggest problems surrounding Zhu Zhongjun, coupled with his strange performance of pretending to be asleep but not cooperating with the investigation of the mirror investigation after he has woken up, as long as the analysis is thorough, this case may be clear.

Thinking of this, Liang Tian suddenly felt a little excited in his heart.

She didn't expect that they had only been in Hangyu City for such a little time, and the case had already made such great progress, and a very suspicious suspect had been locked.

"Xu Luo, you are really amazing!" Liang Tian couldn't help but praise Xu Luo.

What she thought of now, Xu Luo had already guessed after seeing the investigation records, and after seeing Zhu Zhongjun, she completely figured it out.

That's amazing!

"It's alright!" Xu Luo smiled indifferently.

Liang Tian didn't scold him, she was more concerned about another question: "But it's too strange Xu Luo, since you have already seen this?" "

"Then you can completely say it, and use these discoveries to pry open Zhu Zhongjun's mouth, right?"

She still remembered Xu Luo's words, saying that the clues and evidence were not enough, and there were not enough weights to stimulate Zhu Zhongjun to speak, after all, calling would never wake up a person who was pretending to be asleep.

But now it seems that there are many doubts, so you can give it a try.

"The success rate is too low 2.0!"

Xu Luo drove the car carefully, shook his head and said, "Don't underestimate a soldier's willpower and endurance. "

"We are mirror investigators, and it is impossible to force him to speak without evidence, without using unconventional means."

"No matter how suspicious he is, it's just our guess, and he can do it if he doesn't cooperate."

"And once I say it, it's just a scareless!"

"It's better to investigate well, if you can find evidence, you can be beaten to death with a stick!"

"And these points we found are very obvious suspicions on others, but on Zhu Zhongjun, they are helping him clear his suspicions, which makes me think that he is very unlikely to be a murderer."

"Huh?" Liang Tian's eyes widened suddenly, and he asked suspiciously:

"Instead, he helped Zhu Zhongjun clear his suspicions?"

"How so?" _
