After obtaining further evidence corroborating the victim's identity, the police then began investigating the victim's acquaintances and checking who he had last seen before his disappearance. The fingerprints from the travel bag were eventually matched to those of a suspect.
最後警方進一步確定死者身分，又依此調查死者生前的交往關係，失蹤前見面的朋友等，比對採到的指紋，終於找出兇嫌。
