Mu Qiqi searched and observed the deceased's room carefully.
Old Cheng and the others had questioned the deceased's friends and colleagues and came to a unanimous conclusion that Bai Xinyi was a cheerful girl who had a reasonable plan for her life. Everyone had been surprised by her suicide.
Old Cheng couldn't get anything else, so he returned to the crime scene.
"Qiqi, did you get anything?"
"I didn't find anything related to the man on the business card." Mu Qiqi stood up and said, "I'd like to ask, how was the relationship between the deceased and her mother?"
"According to her friends, the deceased's parents divorced in her early years and she lived with her mother. After she graduated from university, she started working at Changrong Electronics. It's been almost three years. Her mother seems to be ill. She also bought a return ticket. Moreover, according to the phone records, she and her mother have been in frequent contact recently."
