Door-to-door dragon son-in-law

Chapter 1145 A little tricky
As soon as Wang Dongxue heard that it was bed No. [-], he immediately realized that he was talking about his father, so he hurriedly asked, "Hello, what's the test result of the patient in Ward No. [-]?"

The man looked hesitantly at Wang Dongxue, then at Director Chen, wondering whether he should continue talking.

Director Chen hurriedly urged: "Xiao Liu, if there is any result, just tell me directly, don't dawdle!"

The man hurriedly said: "That's it. The laboratory first detected excessive mercury in the blood of the patients in the No. [-] ward, and then sent the blood samples to the laboratory of the judicial department for further testing of toxic substances. A large amount of 'Mercury Dichloride' was detected!"

"What?!" Director Chen exclaimed, "Mercuric dichloride?! Are you sure it's mercury dichloride?!"

"Sure!" the man said hastily: "The police suspect that someone poisoned, so they are ready to file a case, and they will probably come over soon."

Wang Dongxue turned pale with shock, and blurted out, "Director Chen, what is mercury dichloride?!"

Director Chen explained: "Mercuric dichloride is a highly toxic inorganic substance. This substance is extremely toxic. On average, taking one milligram per kilogram of body weight can reach a semi-lethal dose! An adult male weighing [-] kilograms only needs Eighty milligrams!"

Wang Dongxue asked: "What is a semi-lethal dose?!"

Director Chen said: "The semi-lethal dose is the standard for medical and chemical toxicity monitoring. For example, a hundred mice are used to test the toxicity of mercuric dichloride. At that time, fifty mice died, and this amount is called the semi-lethal dose."

Wang Dongxue exclaimed: "This kind of substance only needs a few tens of milligrams to kill a person?!"

Director Chen nodded, and said lamentably, "This kind of thing is extremely toxic, especially to the kidneys, just like paraquat is extremely harmful to the lungs, there is almost no cure..."

Wang Dongxue became nervous all of a sudden, and blurted out, "Why did my father take this poisonous substance? No one in our family has ever been exposed to such highly toxic chemicals..."

Director Chen said seriously: "Since the police are going to file a case for investigation, it is very likely that someone intentionally poisoned it!"

"Poisoning?!" Wang Dongxue said suspiciously: "My father spent most of his life teaching and educating people. He has peaches and plums all over the world, and he has received countless honors. Whether it is character or morality, he is impeccable. If he hadn't made enemies with anyone, who would have done this to him?!"

Director Chen hurriedly said: "Wang Dong, it's useless to rely on speculation on this kind of thing. We have to rely on the police to conduct in-depth investigations before we can find the murderer behind the scenes!"

Just as he was speaking, the door of the office was pushed open, and several police officers in police uniforms walked in with solemn expressions.

One of the middle-aged men with a square face walked in front, came directly in front of Director Chen, and said, "Hello, I am Sun Wenbin, the deputy captain of the Jinling Criminal Police Brigade. A patient named Wang Chengyuan in the hospital is very likely to be poisoned, would it be convenient for us to meet Wang Chengyuan's family?"

Director Chen immediately pointed to Wang Dongxue and said, "Captain Sun, this is Wang Chengyuan's daughter, Ms. Wang Dongxue."

Sun Wenbin was a little surprised, and immediately put away his surprised expression, and said seriously: "Hello, Ms. Wang, I'm Sun Wenbin, how is your father's situation now?"

Wang Dongxue said hastily: "Captain Sun, my father is in a very bad condition now. His kidneys are failing rapidly in a short period of time, and his life is in danger at any time... Please find out the murderer who poisoned my father!"

Sun Wenbin nodded very seriously, and said, "Ms. Wang, can you please recall for us, does your father have any enemies? Or has he ever had any financial disputes with anyone?"

Wang Dongxue shook his head and said, "My father has been teaching and educating people conscientiously for so many years. He never fights or grabs at work, and is very helpful. There has never been any conflict with anyone."

Sun Wenbin asked again: "Then, has your father eaten any strange food recently, or been exposed to any strange things?"

Wang Dongxue continued to shake his head: "It doesn't seem to be true, everything was normal before he got sick..."

Sun Wenbin then asked: "Do you usually live with your father?"

Wang Dongxue nodded: "Living together."

Sun Wenbin continued to ask: "Then besides you and your father, who else lives with you?"

Wang Dongxue said, "And my mother, we are a family of three."

"Okay." Sun Wenbin nodded, then asked after a pause, "Is there any nanny or hourly worker at home?"

"No." Wang Dongxue said, "I want to find a nanny for them, but my parents have been intellectuals all their lives, and they are not used to having someone take care of them. In addition, they are only in their 50s now, and they can take care of themselves completely, so I never found a nanny, nor did I find a part-time job."

Sun Wenbin asked: "You and your mother don't have any problems, right?"

Wang Dongxue shook his head: "No."

Sun Wenbin nodded and said: "The three of you live together, and you and your mother have no problems, so it can basically be inferred that it is not something happened to the food or water source in your family."

As he said that, he asked again: "Ms. Wang, I need you to recall carefully. During the period before your father's physical signs appeared, was he alone or went out to eat with his friends?"

Wang Dongxue thought about it carefully, and said seriously: "No, for a period of time before my father's physical problems, because it was winter vacation, he was reading at home all the time, and he hardly went out, so he didn't go out to talk to others. We've had a party."

Sun Wenbin couldn't help frowning: "It's a bit strange to say that, according to the test data, there is a large amount of mercury dichloride in your father's body. This highly toxic substance can enter the body through the mouth and nose, and it may also enter through the skin. in vivo."

"However, our experts speculate that such a large toxic dose may take a long time if it is only applied to the skin, so the most likely way is to enter through the mouth and nose, and oral administration is the most likely."

"However, according to what you said, it's unlikely that your father was poisoned by food and drinking water at home, but he didn't go out to eat or have a party..."

"Then, it might be tricky to figure out where he was poisoned!"
