In that case the questions are: was it suicide or homocide, and, if homocide, who did it?
ETA: In this case, accident would also be possible. For example, getting lost on a hike. Also, after several months, remains would not be pristine...
Until police are confident that all the facts prove the final conclusion, they won't release anything. Once it's out in public, they don't want to retract and say 'oops, changed our minds'.
