Wu Shengnan glanced at Gu and continued, "You might also say that the suspect has some special fetish, so he keeps going back to the crime scene. If it's a special fetish, so much time has passed, and the victim has already been processed into a dried corpse, which barely weighs anything and is very easy to move. The suspect could move his... according to your logic, let's call it a 'work,' he could move his work to a hidden place for both collection and convenient appreciation. More importantly, he would have plenty of time to deal with the crime scene. This way, he wouldn't have to frequently appear in the community, thus avoiding leaving an impression on the security guards, and the crime scene would not be easily discovered. Even if it were found, by then, a long time would have passed, and the victim would be treated, at most, as a missing person."
