What impressed me deeply was "The Death of a Dog"
This is a case in the second part, related to Achen and Yisheng (Zheng Jiaying). A skeleton was unearthed from the reservoir, and after a portrait restoration by the Forensic Department, it turned out to be that of a deceased dog. Achen and Yisheng had fought with a dead dog in the reservoir more than ten years ago, which aroused Ma Guoying's suspicion. At this time, someone even used photos of Achen and the others fighting with the mourning dog to blackmail Achen. Under Guoying's careful planning, they finally found Feng Tian, ??the private detective who blackmailed Achen. From this clue, I found Yang Feng, the wife of Sang Gou, and then learned that Sang Gou had many "mistresses", that he also had sex with other people's wives, and that he had received "threatening letters."
By analyzing the evidence found by Guoying, Ouyang confirmed that Miaoyun was also a woman related to Sanggou, and also found out that Miaoyun's husband had threatened Sanggou. No one would have thought that the person who finally killed Sanggou would be "Miaoyun's son", Sanggou's biological son.
This case was quite touching in the end. Guoying and the others helped Miaoyun's son find evidence of self-defense murder, hoping to get a lighter sentence...
? ? Yanbo put the threatening letter with Comparing the calligraphy written by Zhihui, he found that it was the same person, so Guoying detained Zhihui for investigation. Zhihui finally revealed the secret he had hidden in his heart for many years, but he was so excited that he had to be sent to the hospital for treatment; Miaoyun was even more worried when he arrived at the hospital. Yanbo went to Xiaorou for dinner and saw that she was looking for information on the Internet for Xiaogang to learn boxing. Yanbo even accidentally discovered a clip of Sanggou's boxing match online.
When Shi Zhengji called and said that the test results confirmed that there were no genetic diseases that Zhihui had, Miaoyun became even more confused after hearing this. Zechen found out that Zhengji's small molars were the same as those of the cast of the mourning dog. Zhengji could only tell the story of how he met the mourning dog. Guoying is therefore determined to find evidence for Zhengji that he killed the dog in self-defense. Miao Yun went to the crime team to thank everyone for their efforts. Yan Bo and others also admired Gu Ying's sense of justice.
