The City Police Department conducted an overnight interrogation led by Xiao Sun, questioning the director of the psychiatric hospital and Zhou Hong. Meanwhile, Wu Shuang led a small team to the district-level hospital in the North District to take custody of Zhang Qiang's attending doctor. Once the doctor was detained at the North District Police Station, Wu Shuang immediately headed to Xuefu Road and found Zhang Qian in the student cafeteria.
"Why is it you guys again?" Today was her payday, so the cafeteria foreman agreed to give her half a day off. She planned to take her child out to play but ran into Wu Shuang at the cafeteria entrance.
"Zhang Qian, we now suspect that you are involved in Zhang Qiang's death. Please come with us!" Upon hearing this, Zhang Qian didn't show much reaction. She placed the money she just received into her bag and tidied her hair.
