These cases are not much different from the vast majority of cases.
The suspects, Li Baowei and Qin Xiaohui, were actually already under police surveillance from the very beginning.
Although they were not initially identified as suspects, the police had contact with both during the investigation and interviews.
However, during the handling of the case by the Quanzhou Criminal Investigation Team, there was not enough direct evidence, so they did not reach the level of suspecting their involvement.
Even when the major case team got involved later, and found the possibility of suspicion concerning Li Baowei, he almost slipped through the net due to his alibi.
On the other hand, it was the opposite for Qin Xiaohui; throughout the investigation, she provided a considerable amount of information on Wang Jingya.
