Arc 143The Headless Corpse Case
Su Qiao investigated a headless woman’s corpse and suspected it was linked to Ding Peixin’s disappearance, while her staged romance with Du Muhan grew into a closer connection. DNA testing ruled out Ding Peixin as the victim, but new leads about Sun Zhihao and Xia Xiaolin kept the investigation open.
- Du Muhan reported that the acid-damaged corpse’s cause of death was unknown, and Su Qiao joined him in the autopsy room to investigate.
- Su Qiao dissected the waterlogged body and identified possible ether inhalation, wire strangulation, and exposure to an industrial chemical.
- Su Qiao asked Du Muhan to pretend to be her boyfriend in front of Tao Junhui, and she told Tao Junhui she was giving Du Muhan a chance.
- Su Qiao connected the corpse’s timing and dumping location to Ding Peixin’s disappearance, but the team questioned the theory because evidence supported Ding’s apparent suicide.
- Su Qiao investigated Sun Zhihao and Auntie Li, noting Sun’s nervousness and lack of grief and Auntie Li’s suspiciously quick answers.
- Du Muhan and Su Qiao discovered they lived in the same apartment complex, and he shared his pets, books, and personal history with her.
- Su Qiao learned that Sun Zhihao had cheated on Ding Peixin and that Ding had depression, but DNA testing showed the corpse was not Ding.
- Su Qiao challenged Su Xiyan’s conduct at work, then joined Xiao Li, Liu Juntao, and Liu Liu to question Gu Xue about Sun Zhihao and Xia Xiaolin.
