Xie Houshen, who was at the police station, only revealed the truth after the patient questioning by the police.
However, the police weren't inclined to believe him at first.
A thorough investigation was necessary.
Xie Houshen could provide only limited information, only a phone number.
When the police called the number, they discovered it was out of service.
It was clear to the police that either Xie Houshen had given them a fake number, or those people had been using a disposable number.
And currently, the police were more inclined to believe the former.
Yet, when the police learned that Xie Houshen indeed had a sister in Nandu, their perspective seemed to shift.
Especially after they found out from her bubble tea shop employer, who said she hadn't shown up for work in several days.
The police began to reassess their ideas about the case.
The credibility of what Xie Houshen had said increased.
But, this proved nothing, as the police were clueless.
