Chapter 1062: Markov Test

Zhuang Mengdie couldn't help but exclaimed, "Huh? This Hongying died at the age of 25. It's a pity that she is so young and beautiful."
Old Zhang said, "Well, so many historians believe that Hongying's death was murder."
Ye Tiandao, "Then who will kill her?"
Lao Zhang sighed, "The most likely thing is that Prince Rui’s Fujin or Side Fujin did it. Hong Ying was known as the number one beauty in the Qing Dynasty at the time, and she was greatly loved when she married into the Prince’s Mansion, which made Prince Rui’s wives and concubines jealous. It is estimated that the female relatives hated her for a long time. So killing her is a delightful thing for the female relatives. Of course these are just speculations by historians, and the specifics need forensic verification."
He Chuyao said, "Can this Hongying's body be dissected?"
Lao Zhang shook his head, "No, it's better not to destroy the broken body. We plan to put her body in a crystal coffin and display it like the female corpse of Mawangdui unearthed in Changsha. So the integrity of the body must be maintained."
Zhuang Mengdie frowned, "Then how can we examine the cause of death of this female corpse without being dissected?"
Old Zhang said, "It's not that the autopsy is not allowed, the blood in the corpse moves, the complexion changes, if it rots, how can it be exhibited? He forensic doctor, we now need you to find out the cause of her death, but, the premise Yes, don't dissect the corpse."
Lao Zhang emphasized the last sentence, Ye Tian, ​​Zhuang Mengdie and He Chuyao looked at each other.
After a while, He Chuyao coughed and coughed, "I have a solution. Isn't the Qing imperial family prevalent in poisoning and killing people? For example, the cruel empress Dowager Cixi poisoned her sister, son, and daughter-in-law one after another. At that time, compare The mainstream poison is arsenic. This Hongying's death may also be killed by arsenic. Using arsenic to kill people has a quick effect. Once taken, immediately fall to the ground and die. Otherwise, give the victim a little bit every day, and after a while, Can successfully kill the victim. The key is that the level of medical skills at that time was low, and many poisons could not be detected."
Zhuang Mengdie said, "He forensic doctor, are you now sure that this Hongying was poisoned to death?"
He Chuyao nodded, "I dare not say 100%, it should be said that I am 80% sure. Before forensic toxicology was officially born, most of the bizarre death cases should be poisoned deaths. The more famous Wu Dalang death case in history, no Is it because Pan Jinlian used arsenic to poison him? Even closer, Emperor Guangxu also died of arsenic poisoning."
Ye Tiandao, "The poisoned one, don't you need to dissect the body to check the contents of the stomach?"
He Chuyao said, "No, I only need a strand of hair from the deceased. For arsenic testing, a strand of hair is enough."
Lao Zhang nodded, "Hair is fine, as long as it doesn't damage the body."
He Chuyao took out a small pair of scissors from the backpack he carried, cut off a strand of hair from the female body, and put it into the evidence bag.
Lao Zhang curiously said, "Comrade forensic doctor, how do you cut her hair? It's not like the relevant department inspected whether Emperor Guangxu died of arsenic poisoning. What kind of neutron activation, X-ray fluorescence analysis, and atomization were used by the atomic energy scientists of the Chinese Academy of Sciences? Fluorescence to check whether her hair seems to contain arsenic?"
He Chuyao smiled and said, "Isn't it just a test of arsenic? It would be so troublesome, and the scientist should be asked to do it himself? If we forensic doctors want to test whether the deceased died of arsenic poisoning, we only need to use the Markov method."
Lao Zhang said in amazement, "Ma's test of arsenic?"
He Chuyao nodded, "Yes, as early as 1836, the chemist James Marcy invented a method to test the minimum dose of arsenic. It is called the Markov test method. The sample to be tested is placed on a zinc plate and placed in a U-shaped test tube. , Add acid to generate hydrogen, and heat the reaction. If there is arsenic, it will condense in the cooling part of the test tube to form an arsenic mirror after combining with hydrogen. This method can measure at least 0.007 mg of arsenic for criminal investigation. The reaction equation is: As2O3 +6Zn+12HCl=2AsH3+6ZnCl2+3H2O."
Old Zhang said, "It turns out that the arsenic in the hair can be detected as early as 1836."
He Chuyao said, "Yes, so we forensic doctors have to examine a large number of corpses. If we need to ask scientists for even small things like arsenic inspection, wouldn't it be too busy for scientists to die?"
Old Zhang said, "When will this experiment be done? It's best to do it immediately. We are now anxious to know the cause of Hongying's death."
He Chuyao said, "I definitely can't do it now. This experiment requires reagent test tubes, which are not available here. Don't worry, wait for me to go back, finish the experiment, and call you."
Lao Zhang nodded, "Okay, then I will wait for your call. We must find out the cause of Hong Ying's death. This is a big mystery in history."
Zhuang Mengdie said, "By the way, do you know how this Mochizuki Gege died?"
Lao Zhang sighed, "Mochizuki Gege, this Mochizuki Gege is even more sad. When he died, he was only 19 years old."
Ye Tiandao, "What about the cause of death? How did those historians analyze Mochizuki Gege's death?"
Old Zhang said, "When Hongying died, Mochizuki Gege was only 6 years old. She was smart and lovable since she was a child. Moreover, she was born a beautiful embryo, and she looked like her mother. This is very wise. The love of the prince. The death of Hongying made Prince Rui very disappointed, so he transferred his love little by little to his daughter Mochizuki Gege, and this love gradually evolved as Mochizuki Gege grew up day by day. A deformed emotion."
Zhuang Mengdie exclaimed, "Deformed emotions? Isn't it a father-daughter love?"
Lao Zhang nodded, "Yes, it's father-daughter love. So, how can the Qing imperial family tolerate this kind of abnormal love. This matter quickly spread throughout the royal family. This abnormal love affair soon spread. In the ears of Prince Rui’s father, Prince Fu, Prince Fu flew into a rage, thinking that Prince Rui and his daughter were unreasonable and messed up the family tradition. So Prince Fu put arsenic in the beauty soup and ordered the maid to give it to Mochizuki Gege. Mochizuki Gege didn't know that the soup was poisonous, and after drinking it, he immediately poisoned him and died. Because of the secret of doing this, even Prince Rui himself did not know the cause of his daughter's death."
Ye Tiandao said, "It turns out that Mochizuki Gege was poisoned to death, not because of illness."
Old Zhang said, "Yes. In the final analysis, Mochizuki Gege’s tragedy is also to blame Prince Rui himself. If he hadn't been obsessed with Hongying too much, how could he have done something that is not embarrassing or embarrassing with his own daughter to attract criticism? It is said that while Prince Rui was dying, the name of Hongying was what he said in his mouth. It can be seen that he loved that Hongying much."
Zhuang Mengdie sighed, "If you love someone to the point of being infatuated, you can only become crazy. Love the house and the black like Prince Rui, it really can only make people sigh."
