Detective Training Manual

Before he spoke, all eyes were focused on him.

"What is it?" several people asked.

Zhao Shengrui panted, and turned the report page to the people in the conference room...

Several close ones frowned and leaned forward to see the words in the report clearly.

"This is...?" they mumbled.

The next few people who were too far away from the eyes yelled anxiously: "What are you writing? Hurry up."

"Whhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh. -Urea]???"

There was a silence...

Half of the people in the room looked at each other dumbfounded: "This...what is this?"

But half of the people seemed to really know what it was, so they frowned, bowed their heads, or pondered.

Edwards and Old Man Gu are naturally part of the contemplation.

Zhou Yan scratched his head. Although some strange medical knowledge appeared in his mind from time to time, he knew nothing about this chemical equation.

So... what is this thing?

I was thinking...

"Insulin promoter." Zhao Shengrui seemed to finally get his breath, and began to read according to the test report: "It is a raw material used to make medicines, mainly used to make hypoglycemic drugs for diabetic patients."

"Glucose-lowering drugs?" Although everyone doesn't know what the equation is, when it comes to hypoglycemic drugs, almost everyone understands what it is, and is slightly surprised.

"Yes, hypoglycemic drugs can promote the pancreas to secrete insulin, and it can also synthesize a small amount of insulin in the human body. The entire interior of the teapot is filled with this concentrated preparation." Zhao Shengrui continued.

Speaking of this, several people raised questions: "Uh, speaking of it, it seems to be conceivable that long-term drinking with this teapot may cause hypoglycemia, but... this kind of thing is not inside the teapot. Well, it won’t come into direct contact with water, can it enter the human body by citation?"

The voice hasn't fallen...

"Yes." Another detective gave the answer categorically: "The density of pottery baked at high temperature is very low, and some pottery has water in it. After a long time, the outer wall will feel wet, so if there are other materials inside, It should be able to penetrate into the water, but the dose is very small."

"Yes, the dose is very small." Zhao Shengrui began to say again: "It is written in the report that the activity threshold of this reagent is exactly between 97-105 degrees!

In other words, if you use this kind of pot to make tea, if you touch the water that has just been boiled, a certain amount of medicine will penetrate into the water.

Long-term drinking will reduce blood sugar, but because the dose is too small, it will not cause coma.

So I suspect that the teacher may have been in a low-carb and low-sugar body environment for so many years. "

"Long-term low glucose will lead to slow secretion of the pituitary gland, insufficient blood oxygen content, reduced hemoglobin activity, low oxygen in the organs, and accelerated exhaustion. The failure will be three years or five years. The body of an elderly person will definitely not be able to persist too much. Long time." A detective who seemed to be a doctor took the stubbornness.

Just after speaking, some people also raised doubts.

"Wait, this is not right. If this is the case, why can't the autopsy show it? This should be regarded as a typical drug poisoning."

"No, if it promotes the secretion of pancreatic islet B cells, there will be no toxic reaction, because insulin is a self-regulating hormone of the human body. There will be no abnormalities in the resulting organ failure, because The deceased is already very old. Regardless of whether it is a blood sugar problem or not, people at this age will not respond well to their organs." This question was answered by Sister Yingli.

Not finished yet...

"Then there is something wrong, too much insulin is secreted under the stimulus of the drug, will the drug remain in the body, and this teapot Zuozhongtang has been used for six or seven years."

A detective in a room doesn't have to hesitate at all if there is any doubt, it will be dug up directly.

And as soon as this sentence was finished, Zhao Shengrui also took the stubbornly.

“Well, that’s what I’m going to say next. It’s written in the report that this preparation will be made into a sulfonylurea secretion accelerator such as [gliquidone], which can only exist in the human body for three times. In about an hour, as long as the person is not suffering from renal failure or severe liver disease, the metabolic rate is 100%. Therefore, even if a diabetic patient takes a large dose of hypoglycemic drugs all year round, his blood sugar will recover within ten minutes as long as the drug is stopped. Because there will be no trace of medicine left in their bodies."

"100% metabolic rate?"

"Yes, this is the characteristic of this medicine. It is not only 100% metabolized, but also consumed within three hours." Zhao Shengrui said again.

Then, another question was raised.

"Then there is something wrong, because if this kind of medicine is mixed into the tea in the Zuozhongtang, it will also form adhesion to the surface of the teacup or teapot, but the first test just now, why can't it be found out... ...."

"This reagent is completely insoluble in water." Zhao Shengrui once again shook the report sheet in his hand and said: "Many people with diabetes who take sulfonylurea secretion promoters will find a phenomenon that the tablets fall into the water for a long time while taking the medicine. After a week or even a few months, they will still remain in the form of a'pill' until you touch them, and they will not disperse.

After drinking tea every day, the teacher will wash the tea set with cold water, because if the tea stains are not cleaned frequently, it will rust on the tea set.

Coupled with the fact that the medicine is insoluble in water ~www.readwn.com~ and has no adsorptive characteristics, this habit has become an act of unconsciously destroying evidence. "

After speaking, everyone frowned.

A kind of medicine taken by diabetic patients, sizzling - although it is very common, it is concentrated, and the temperature and characteristics are used to integrate it into the tea set, combined with the victim's habits, age, and other factors. Come together...

How much information must be aggregated to achieve this kind of murder.

Moreover, this teapot was used in Zuo Zhongtang seven years ago, so at that time, someone had already begun to design to kill him.

A murder, was deliberately filled with a speed of 7 years...

Just thinking about it, suddenly, a person had a question again.

"Wait, it's not right, Zuo Zhongtang should have been to the hospital in the past 7 years. Even if he has not had any disease, he has been tested in general. If he is always in a state of low blood sugar, then take a blood test. No Did you just find out?! Why can it continue without being discovered for so many years?"
