Questions that an <span title="Anthropologist/Sociologist/Psychologist">Anthropologist/Sociologis...</span> might as re: Missing person case?

Question

It's a school project - I need five questions from each type of social scientist. Specifically, this is about the Cedrika Provencher case of the girl missing in Quebec, but they can be generalized or apply to another case. All ideas welcomed.

Answer 1

s*x, murder, money,  who profits from the disappearance of this person?  Did a person abuse her/  kill her/  hold her for ransom?  Motive

or.  she became ill and is lost, she wanted to get away and just left.

Police will question the family, friends and co -workers.

Sometimes they find a body.  sometimes the person is never found.
