When the detectives know the victim's identity they will inform their relatives or loved ones of their death and attempt to get more information on the victim's life and possible suspects. The detectives continue their investigation by interviewing witnesses and possible suspects, all the while tracing the victim's last known movements and victim's state of mind (by talking to the victim's family, friends and co-workers). Sometimes they will have someone they suspect of the crime and in checking their alibi they will trace the last known movements and the state of mind of the current suspect by talking to the people in the person(s) life until they are either ruled out or dead certain of the guilt of the person they suspect.
