I know that in the case of missing/kidnapped children, law enforcement will try to get the parents or a liaison rep in front of the camera and use the child's name, talk about them in great detail, all to make them seem human, a person. This is done because the kidnapper or whomever has the child may see the piece and the impersonal nature of the act may somehow become humanized. The experts believe that if the victim can be given a name, a face, a history (of caring by family and friends), it makes harming the victim harder. Not that it won't happen, because some killers just cannot be stopped no matter what you try to do. But like humans, serial killers come in all types and you're hoping to find some chink in his armor, some remorse, some level of consciousness that you can reach to perhaps influence the killer, either to let the victim go, or to confuse them enough to give you enough time to find the victim. Sadly, I think the stats for missing kids abducted is that 90% are killed within hours of the abduction.

Serial killers are a different breed and again, there are all kinds. I think in Vincent's case, they will find when they profile him that he can feel remorse, which is ultimately what will get him caught. Some other killers, such as Ted Bundy, never ever showed remorse. Well, remorse for getting caught, but none for their victims.
