The eighteenth episode

Nurse Chen, upstairs in the ward of the provincial hospital, suddenly reported to the major crimes unit that her cousin had never appeared since she was discharged from the hospital. She wondered what had happened. Then Jing Yun immediately remembered the mysterious arson case. The body of a young female has not been confirmed. Could it be Chen Xiaoyan?
