The police increased their efforts to solve the case, and the officers in the technical department went all out, using all kinds of advanced technical means to analyze the collected evidence in depth. They sat in front of the computer, their eyes staring at the screen, their fingers tapping rapidly on the keyboard, a line of code and data flashed quickly on the screen.
Through the deep data recovery of Xiong Yufang's cell phone, the police obtained more key information hidden in it. They discovered Xiong Yufang's chat logs with some mysterious people, which were full of cryptic coded messages and transaction details about the channels of purchasing the poison, how to use it, and how to evade police tracing. One of the chat records shows that Xiong Yufang asked the other party for a highly effective and undetectable poison, and the other party replied with the specific name and price of the poison, and told her to be careful when using it to avoid leaving traces. These chat records were like a heavy bomb, exposing Xiong Yufang's crimes.
When tracking Xiong Yufang's online activities, the police found that she frequently browsed a number of illegal websites before the crime, which specialize in providing information on the trading of various prohibited items. She registered an account on one of these sites and communicated with the seller several times, eventually reaching an agreement to buy the poison. The police locked the identity and location of the seller through technical means, and it turned out to be a criminal gang hidden in a remote area, who had long been engaged in illegal drug-trading activities that jeopardized society. The police quickly launched an operation and successfully dismantled the criminal gang, eliminating all those involved. This action not only provided more conclusive evidence for this case, but also eliminated a major hidden danger for the society.
At the same time, the police carried out a more detailed analysis of Xiong Yufang's call records, using voice recognition technology and big data comparison, and found that she had talked to a number of suspicious numbers before and after the poisoning of her child. The time and duration of these calls are highly consistent with the key time nodes of the case. One of the numbers had a brief call with Xiong Yufang a few minutes before the child was poisoned, and the police speculated that the call was likely to be Xiong Yufang confirming whether the poison had been successfully placed.
When investigating Xiong Yufang's finances, the police found that her bank account had several unusual cash withdrawal records around the time of the murder. The time and place of these cash withdrawals were very suspicious and did not match her daily spending habits. The police accessed the bank's surveillance video, which showed that Xiong Yufang was panicked when she was withdrawing cash, looking around, and her behavior was very unusual. The police suspect that she withdrew cash to pay for the purchase of poison or to prepare to abscond after the crime.
In addition, the police found a diary in Xiong Yufang's rental house. This diary records the bits and pieces of her relationship with Xiao Xue, which describes in detail how she planned to cheat Xiao Xue's money and how she carried out the plot to poison the child. She wrote in the diary: "Xiao Xue, this stupid woman, is simply my ATM. As long as I exerted a little bit of tactics, she would obediently give me the money. However, her husband is beginning to suspect me, and I must find a way to get rid of this hidden danger. And her two children are the best bargaining chips I have to control her, as long as they die, Xiao Xue will completely break down, and then everything she has will belong to me." This diary was like a sharp blade, completely tearing open Xiong Yufang's mask of disguise and exposing her ugly heart to the sunlight.
The police also conducted a comprehensive combing of Xiong Yufang's whereabouts before and after the murder, mapping out her detailed course of action by integrating surveillance footage from all corners of the city. Surveillance footage shows that after purchasing the poison, Xiong Yufang carefully hid it and then traveled to Xiao Xue's house. In the vicinity of Xiao Xue's home, she observed for a long time to ensure that no one around noticed her before quietly entering Xiao Xue's home. After the child was poisoned, she quickly left the scene and traveled to a remote location to meet with members of the criminal gang, handing over the remaining poison and obtaining a payment.
With the increasing evidence, Xiong Yufang's criminal facts became clearer and clearer, forming a complete and irrefutable chain of evidence. The police once again interrogated Xiong Yufang, when she saw the police took out these hard evidence, her face became white as paper, her body like chaff constantly trembling. Her eyes were full of fear and despair, knowing that she could no longer deny.
In the interrogation room, Xiong Yufang's psychological defense completely collapsed. She sat paralyzed in a chair, her hands hanging helplessly on both sides of her body, her eyes staring blankly ahead. She began to explain her crime process intermittently, her voice as weak as a mosquito fly. She admitted that she had meticulously planned this poisoning and murder in order to satisfy her greed and selfishness. She approached Xiao Xue from the beginning in order to cheat her out of her money, and when she found out that Xiao Xue's husband started investigating her, she felt an unprecedented fear and decided to take extreme measures to kill Xiao Xue's two children in an attempt to control Xiao Xue and continue to get more benefits from her.
After Xiong Yufang finished explaining the crime, she breathed a sigh of relief as if she was relieved, but was soon overwhelmed by deep remorse. She realized how cruel and unforgivable what she did was, not only ruining the happiness of Xiao Xue's family, but also pushing herself into the abyss of doom. She tearfully begged the police to give her a chance to redeem herself, but she knew that the law was just and she had to pay a heavy price for her crime.
The police carefully compared Xiong Yufang's confession with the evidence collected to ensure that every detail was accurate. They are well aware that the detection of this case is not only related to the justice of the victim and her family, but also to the fairness and justice of the society and the dignity of the law. They used a rigorous attitude and professionalism to draw a stage-by-stage conclusion to this tragedy, but for Xiao Xue's family, the pain of losing their child will never be erased.
