After eating until his stomach was full, An Ying burped and followed Yun Pingshi to Mr. Guo's place.
Xiao Yi had already sorted out the situation of Jinling Mansion Academy at Mr. Guo's place and said: "Jinling Mansion Academy is located at the foot of the West Mountain in the north of the city. It is the best academy in the capital and in the country. The students involved this time are mainly a few from Class Jiazi. They are all students who will take the provincial examination next year.”
"Zhu Zhuzhi is the student who brought the rice dumplings. He is the eldest son of the three-bedroom Zhu family in the north of the city. The Zhu family in the north of the city is also a well-established family in the capital. I heard that many of them are officials and have fertile fields and forests, and their families are wealthy. Now the Zhu family's There are more than forty people living in the big house with three rooms. Zhu Zhuzhi has always done well. I heard that he will have no problem passing the provincial examination next year, so he is waiting to take the Jinshi examination."
An Ying muttered: "Well, there are more than forty people in the third room, so the population is quite prosperous."
Xiao Yi chuckled, "The eldest brother of the Zhu family has three rooms for concubines, the second child has four rooms, and the third child not only has three concubines at home, but also has a nostalgia for a brothel."
Lao Guo shook his head and said: "The Zhu family used to be very prosperous. A few years ago, they even had a household secretary. Now they are just resting on their laurels."
Xiao Yi continued: "Shen Pingxiu, one of the students present that day. His grades were good, first class."
Yun Pingshi said: "I know Shen Pingxiu's father. His father has studied for most of his life and has never even passed the provincial examination. His talent is a bit lacking. Usually wealthy people can only afford education, but his family is mediocre. He didn’t get married until he was in his twenties, and he has been studying and taking exams since then, all of which were supported by his wife. The money for Shen Pingxiu’s education came from the Shen family in Huzhou. The Shen family always felt that he had a good future, so they gave some money to subsidize him. "
An Ying said "Oh", thinking that it must be Mrs. Shen's handiwork. She has always liked investment, investing in industries or people.
"The other one is Yang Ye. He works as a handyman in our Criminal Department and does record-keeping work. He was also recommended by the academy. He was also there that day. You all know about Yang Ye's situation. The son of Yang Baotou, the capital government official, I always get first-class grades, and I rely on rewards from the academy and subsidies from our Ministry of Punishment to study."
Xiao Yi said: "I think this person is very suspicious. Liang Su, from the Liang family in Shandong. The Liang family has been doctors for generations, and his ancestor was the imperial physician in the palace. Judging from his family background, he knows medical skills. You see, we basically It is certain that the poison that poisoned Zhu Kexin came from the extraction of oleander. This extraction requires skills, and ordinary people..."
Guo Xi knocked on the table and said, "Xiao Yi, don't jump to conclusions. You should introduce others first."
Xiao Yi reluctantly took out another stack of paper.
"Feng Mo, a native of Baofeng, Yuzhou. He passed the Yuzhou Provincial Examination a few years ago and came to the capital to take the imperial examination but failed, and later entered the Jinling Academy. He works as a farmer in his hometown and has a wife in his hometown. In addition to studying in the academy, he also gives Make some money by copying books in the bookstore."
"The last one is Yang Shen. He is from Quanzhou. He is special. He originally joined the army. Five years ago, he gave up martial arts and studied literature. He ranked third in the Fujian Provincial Examination. After arriving in the capital, he took part in the Jinshi Examination and failed repeatedly. According to someone's introduction Entered Jinling Mansion Academy to study."
An Ying asked while looking at the case file: "How come there is no information about Zhu Kexin who was poisoned to death?"
Xiao Yi was stunned and said: "Zhu Kexin cannot be the murderer, nor is he the real victim. There is no investigation into him. Do you think he poisoned himself?"
An Ying read the case file at a glance and said: "I just think everyone involved in the case needs to be investigated carefully."
Guo Xi tapped his fingers on the table and nodded, "Zhu Kexin is the nephew of Zhu Yu, the imperial censor. He is from Wuxian County, Jiangsu Province, and is a cousin of the Zhu family. When he first came to the capital, he lived with the Zhu family, and later moved out on his own. Jinling Mansion Academy There is not much information about him. I talked with the headmaster of the academy. He originally studied in Wuxian County and had some talent, so his family sent him to the Zhu family, and he was introduced to Jinling Mansion Academy through the Zhu family."
Yun Pan read the case file and said, "Your Excellency, you focus on these six students. I fully agree with this."
Xiao Yi was a little puzzled, "Why? What if it was poisoned by gangsters on the road, or poisoned by people in the academy kitchen? These are all possibilities."
An Ying said slowly: "Mr. Guo has written a supplementary test report for his work in the later file. Judging from the extent of the poisoning, the poisoning will not last more than six hours. And Zhu Zhuzhi left home in the morning. In the academy, the poisoning at home has been eliminated, so they cooked rice dumplings to eat that night. Although Zhu Zhuzhi stopped twice on the way, the rice dumpling gift boxes were watched by the driver, and there was no chance for outsiders to get close. "
"That is to say, the time period for poisoning the rice dumplings can be narrowed down to Zhu Zhuzhi's two hours from noon to dinner, and the only people who can come into contact with the rice dumplings during these two hours are these five people and the people in the kitchen."
Yun Pan nodded with satisfaction and continued: "The people in the kitchen are usually responsible for three meals a day for the entire academy. If you want to poison Zhu Zhuzhi, you can poison Zhu Zhuzhi's meals at any time. There is no need to specifically poison Zhu Zhuzhi. The rice dumplings we brought were poisoned."
"At that time, Zhu Zhuzhi also told the people in the kitchen that this was for the classmates to eat together. The success rate of poisoning at this time was too low. This case is strange. This way of poisoning seems very casual and nothing special. point."
Xiao Yi became even more confused, "Then according to what you say, isn't this just an accident? Is there really a murderer? What if someone in the kitchen accidentally put poison or something, how can we find out?"
Yun Pan also said: "So the young men in Beijing thought the same way at the time. After searching and searching, there was no special direction, so they concluded that the case was an accident."
"But judging from the fact that the murderer deliberately used oleander stems and leaves, this must be a planned poisoning. Now the main suspects are still those students." Guo Xi lowered his head and said meaningfully: "Although They all have a bright future, but their hearts are unpredictable."
Yun Pan said to Guo Xi: "I remember that during the investigation, I said that Zhu Kexin and Zhu Zhuzhi had a very good relationship. They basically ate and slept together. At that time, Zhu Zhuzhi took the cooked rice dumplings to the canteen and called the people who were there at that time. There were about a dozen students in the dining hall. After he picked a rice dumpling, Zhu Kexin happened to come in from outside. Probably because there were no more rice dumplings, he asked for the rice dumplings from Zhu Zhuzhi's hand. The two of them were close, and Zhu Zhuzhi He handed the rice dumpling in his hand to Zhu Kexin."
Yun Pan glanced at An Ying and continued: "An Ying said before that if you want to poison someone, you must ensure that the person will eat it, so it is unlikely that the Zhu family will poison someone. . But I feel that if we push things backwards, no one can guarantee that the rice dumpling Zhu Zhuzhi picked is poisonous."
As soon as these words came out, Guo Xi and An Ying looked at each other. Guo Xi couldn't help but be excited in his words: "Yun Pan's words reminded me. Only Zhu Zhuzhi can guarantee that the rice dumplings he picked are poisonous. That one!"
A flash occurred in Yun Pan's mind, but before he could speak, Master Guo shook his head again and said, "Then how can we guarantee that Zhu Kexin will definitely eat the one in his hand?"
Xiao Yi also said: "Zhu Zhuzhi is the first in the provincial capital to solve the test, and he is also the victim. He will not poison his own rice dumplings and want to poison himself."
An Ying also shook his head and said: "If Zhu Zhuzhi poisoned himself, it would be easier to explain how he ensured that he got the poisoned rice dumplings. But this inference means that Zhu Zhuzhi wanted to poison Zhu Kexin, but how could he be sure that Zhu Kexin Will you ask for the rice dumplings in his hand?
"Although the two have a good relationship, this matter of asking for the rice dumplings from other people's hands must be an accident. Who can guarantee that Zhu Kexin will definitely ask for the rice dumplings from Zhu Zhuzhi's hand? If not, Zhu Zhuzhi will throw them away again Dropping the rice dumplings in your hand will arouse others' suspicion. There are too many loopholes here, and there is no real evidence at all. It is all our own speculation."
"Among these people, Yang Ye has some connections with the Ministry of Justice. Let's ask him first." Guo Xi closed the case file and said to An Ying and others.
